Indlela Izinombolo Zokuqala Nezesibili Ze-IP Ezisebenza Ngayo

Ikhodi ye-IP yakhiwe ngamadijithi amabili ahlukene ezinombolo, ngalinye limelela isigaba esihlukile sokumelana nemvelo. Idijithi yokuqala, esukela ku-0 kuya ku-6, ikhombisa izinga lokuvikelwa kwendawo ebiyelwe ekungeneni kwezinto eziqinile zakwamanye amazwe, kusukela kumathuluzi amakhulu neminwe kuya ezinhlayiyeni zothuli ezincane kakhulu. Isilinganiso esingu-6 simelela ukuqina kothuli okuphelele, okudinga ukuhlolwa kwe-vacuum lapho kungekho uthuli olungangena khona endaweni ebiyelwe isikhathi esithile.

Inombolo yesibili, kusukela ku-0 kuya ku-9K, ilinganisa izinga lokuvikelwa ekungeneni kwamanzi. Lesi sikali asiqondile; sihlanganisa izinhlobo ezahlukene zokuchayeka emanzini, okuhlanganisa ukujiya, ukuconsa okuqondile, ukuchelela, amajethi anomfutho ophezulu, kanye nokucwiliswa okuphelele. Isibonelo, inombolo yesibili engu-5 ikhombisa ukuvikelwa kumajethi amanzi anomfutho ophansi (amalitha angu-12.5 ngomzuzu) kusuka kunoma iyiphi indlela, kanti u-6 ubonisa ukuvikelwa kumajethi amanzi anamandla (amalitha angu-100 ngomzuzu kumfutho we-100 kPa).

Okushiwo yi-IP54, IP55, IP65, IP66, IP67, kanye ne-IP68

Ukuze bahlole ukukhethwa kwezinhlelo ze-PA zesandisi-zwi ezingangeni manzi, onjiniyela kumele baqonde izindlela ezithile zokuhlola zezilinganiso ze-IP zezimboni ezivame kakhulu. Ithebula elingezansi lichaza imikhawulo eqondile yalezi zigaba ezijwayelekile.

Isilinganiso se-IP66 ngokuvamile sibhekwa njengesisekelo sezinhlelo zokusebenza zangempela zezimboni nezangaphandle, njengoba siqinisekisa ukusinda emvuleni enamandla kanye nokwehla kwamapayipi aqondile. I-IP67 kanye ne-IP68 zigcinelwe izinhlelo zokusebenza ezikhethekile lapho isipikha singase sicwiliswe khona okwesikhashana noma unomphela, njengase-imibukiso yezimayini evame ukukhukhulekanoma izakhiwo zokubeka imikhumbi olwandle.

Lokho Izilinganiso ze-IP Ezingambozi

Nakuba isilinganiso se-IP sesipikha sezimboni sinikeza idatha ebalulekile mayelana nothuli namanzi, akuyona inkomba ephelele yokuqina kwemvelo iyonke. Inkinga evamile yobunjiniyela ukucabanga ukuthi isilinganiso se-IP esiphezulu sisho ngokuzenzakalelayo ukumelana nazo zonke izingozi zesikhungo. I-IEC 60529 ayihloli ukumelana kwe-enclosure emisebeni ye-ultraviolet (UV), okungalimaza ngokushesha amapulasitiki ajwayelekile e-ABS ezindaweni zangaphandle.

Ngaphezu kwalokho, izilinganiso ze-IP azimbozi ukugqwala kwamakhemikhali noma umthelela ongokwenyama. Isipikha singase singangeni manzi ngokuphelele (IP67) kodwa siqhubeke nokuhluleka kwesakhiwo uma sichayeka emisipheni ene-asidi esitshalweni se-petrochemical. Ngokufanayo, ukumelana nomthelela kulinganiswa ngokwehlukana ngesilinganiso se-IK (IEC 62262). Isipikha sezimboni esisebenza kanzima singadinga isilinganiso se-IK08 (esikwazi ukumelana nomthelela we-5-Joule) ngaphezu kwesilinganiso se-IP66 ukuze sisinde endaweni yokugcina impahla enabantu abaningi.

Ukukhetha Izilinganiso ze-IP Ngokwendawo Yokusebenza

Ukucacisa isilinganiso se-IP sesipikha sezimboni esifanele kudinga ukuhlanganisa izingozi eziqondile zemvelo zendawo yesikhungo esinikeziwe nemingcele yokuhlola ehambisanayo yezinga le-IEC 60529. Ukucacisa ngokweqile kuholela ekusetshenzisweni kwemali okungadingekile, kuyilapho ukucacisa okungaphansi kuqinisekisa ukwehluleka kwehadiwe ngaphambi kwesikhathi. Inqubo yokukhetha kumele ibhekane nezimo zokusebenza ezivamile kanye nezimo zokulungisa ezimbi kakhulu.

Imikhakha ehlukene yezimboni iletha izinselelo ezihlukile ezilawula hhayi nje kuphela isilinganiso se-IP kodwa futhi nokwakheka kwesakhiwo sohlelo lwe-PA lwe-loudspeaker olungangeni manzi. Ngokuhlukanisa izindawo zesikhungo zibe yizimo zokusetshenziswa ezihlukile, onjiniyela bangenza indlela yabo yokuthenga ibe yijwayelekile futhi baqinisekise ukusebenza komsindo okuhambisanayo ezindaweni ezahlukene zokusebenza.

Amacala Okusetshenziswa Kwangaphakathi, Kwangaphandle Okuncane, Okuhlanzwayo, Nasemanzini

Indawo ezungezile inquma ngqo inhlanganisela edingekayo yokuvikelwa kokungena kanye nokwakhiwa kwezinto. Izindawo zokukhiqiza zangaphakathi ezingenazo izinqubo zoketshezi ngokuvamile zidinga ukuvikelwa kwe-IP54 kuphela ukuvikela uthuli olusemoyeni oluzungezile. Izindawo ezingaphandle kancane, njengezicabha zokulayisha noma izindawo zokukhosela zokuhamba, zibhekene nemvula eqhutshwa umoya kanye nokufuma, okudinga okungenani i-IP65.

Ezindaweni ezibucayi, izidingo ziyanda kakhulu. Izindawo zokuhlanza amanzi ezindaweni zokukhiqiza ukudla noma zemithi zibhekana nemijikelezo yansuku zonke yokuhlanzeka kusetshenziswa amanzi ashisa kakhulu, anomfutho ophezulu axutshwe namakhemikhali abangela ukucindezeleka. Lezi zindawo zidinga izilinganiso ze-IP66 noma ze-IP69K. Izindawo zasolwandle, kufaka phakathiamapulatifomu kawoyela asogwini lolwandlekanye namachweba asogwini, abhekene nosongo olwengeziwe lokufafazwa kukasawoti okuqhubekayo kanye nomthelela wamagagasi angaba khona, okufuna ukuvikelwa kwe-IP66 noma i-IP67.

Indlela Yokuqhathanisa Isilinganiso se-IP, Izidingo Zokufaka, kanye Nokufaka

Isilinganiso se-IP sithembeke kuphela njengezinto ezivalekile kanye nehadiwe yokusibeka eyisekelayo. Isipikha esinesilinganiso se-IP66 asisizi ngalutho uma indlu yaso iqhekeka ngaphansi kokucindezeleka kokushisa noma i-bracket yaso yokusibeka igqwala. Lapho kuqhathaniswa izinketho, onjiniyela kumele bahlole ukusebenzisana phakathi kwesilinganiso se-IP kanye ne-enclosure metallurgy. Isibonelo, insimbi engagqwali ejwayelekile engu-304 ingase ibhoboke futhi yehluleke ezindaweni zasolwandle naphezu kokugcina isipikha esinesilinganiso se-IP67; ngakho-ke, insimbi engagqwali engu-316L ene-Pitting Resistance Equivalent Number (PREN) engaphezu kuka-32 iyadingeka.

Izidingo zokufaka zithinta nobuqotho besilinganiso se-IP. Izindawo zokungena ngekhebula ziyizindlela ezivame kakhulu zokwehluleka kwezikhulumi ezingangeni manzi. Abafaki kumele basebenzise izindlala zekhebula ezilinganiswe kahle (isb., izindlala zethusi ze-M20 IP68) futhi baqinisekise ukuthi amabhuleki okufaka awadingi ukubhoboza endlini yesipika evaliwe, okuzokwenza isitifiketi se-IP somkhiqizi singasebenzi ngokushesha.

Indlela Ukuvimbela Ukungenwa Kwamanzi Okungathinta Ngayo Ukusebenza Kwe-Acoustic

Ukufinyelela isilinganiso se-IP sesipikha sezimboni esiphezulu kuvame ukudinga ukuyekethisa komshini okungashintsha ukusebenza kwe-acoustic yeyunithi. Ukuze kufezwe izilinganiso ze-IP66 noma ze-IP67, abakhiqizi kumele bavikele ama-transducer cones athambile ekucindezelweni kwamanzi. Lokhu kuvame ukufezwa ngokusebenzisa ama-acoustic meshes akhethekile e-hydrophobic (njenge-PTFE membranes) noma ngokuvala ngokuphelele umshayeli ngemuva kwephaneli yangaphambili eqinile, ezwakalayo.

Lezi zindlela zokuvimbela amanzi ziletha ngokwemvelo i-acoustic impedance. Amaza omsindo avame kakhulu awanamandla okungena kalula kuma-membrane aminyene angangeni manzi. Ngenxa yalokho, isikhulumi se-horn esilinganiselwe yi-IP66 singase sibhekane nokwehla okungu-2 kuya ku-4 dB ezingeni lokucindezela komsindo (i-SPL) kuma-frequency angaphezu kuka-8 kHz uma kuqhathaniswa nesilinganiso esilinganiselwe. Abaklami besistimu kumele bacabangele lokhu kuncipha kwama-frequency aphezulu ngesikhathi sesigaba sokumodela se-acoustic, okuvame ukukhokhela ngokwandisa izilungiselelo zokuthepha kwe-amplifier noma ukufaka izikhulumi ngobuningi obukhulu ukuze kugcinwe izinhloso ze-Speech Transmission Index (STI) zokukhishwa kwezwi okuphuthumayo.

Indlela Yokuqinisekisa Izimangalo Zesilinganiso se-IP

Nakuba abakhiqizi bevame ukukhangisa ngezilinganiso ze-IP eziphezulu zesikhulumi sezimboni, onjiniyela kanye nochwepheshe bokuthenga kumele baqinisekise ngokuqinile lezi zimangalo ngokusebenzisa imibhalo ejwayelekile kanye nokuhlaziywa kokuqhathanisa. Imakethe yomsindo wezimboni ifaka phakathi ububanzi bekhwalithi yemishini, futhi ukuthatha imininingwane yokumaketha ngenani elibonakalayo kungaletha ubuthakathaka obukhulu ezinhlelweni ze-PA zokuphepha empilweni.

Ukuqinisekiswa kudinga ukuqonda okujulile kwezinqubo zokuhlola zamazwe ngamazwe kanye nekhono lokuhlukanisa phakathi kwezimangalo eziqinisekisiwe kanye nedatha yelabhorethri eqinisekisiwe. Ukusungula inqubo yokuqinisekisa eqinile kuqinisekisa ukuthi uhlelo lwe-PA lwesandisi-zwi olungangeni manzi olulethwa luzosebenza kahle njengoba luhlelwe ngesikhathi sokuphila kwalo.

Imibiko Yokuhlola kanye Nezindinganiso Okufanele Zicelwe

Ukuqinisekisa isilinganiso se-IP, amaqembu okuthenga kufanele agunyaze ukulethwa kwemibiko yokuhlola esemthethweni evela kuma-laboratories agunyaziwe avela eceleni. Ukuziqinisekisa ngumkhiqizi kuvamile ezilinganisweni eziphansi (IP54), kodwa izimangalo ezisezingeni eliphezulu (IP66, IP67, IP68) kumele zisekelwe ekuqinisekisweni okuzimele. I-laboratory yokuhlola kufanele ibe nokugunyazwa okusebenzayo kwe-ISO/IEC 17025, okuqinisekisa ukuthi indawo inemishini elinganisiwe kanye nekhono lobuchwepheshe lokwenza ukuhlolwa kwe-IEC 60529 ngokunembile.

Lapho bebuyekeza umbiko wokuhlola, onjiniyela kufanele baqinisekise izimo ezithile zokuhlola. Ngombiko we-IP66, imibhalo kumele isho ngokusobala ukuthi isipikha safakwa embotsheni engu-12.5mm ekhipha amalitha ayi-100 amanzi ngomzuzu ebangeni elingamamitha angu-2.5 kuya kwangu-3 okungenani imizuzu emi-3, nokuthi ukuhlolwa kwangaphakathi okulandelayo akubonisanga ukungena kwamanzi okuyingozi.

Indlela Izilinganiso ze-IP Eziqhathaniswa Ngayo Nezinye Izitifiketi

Ezimakethe zaseNyakatho Melika, onjiniyela bavame ukuhlangana nezinga le-NEMA 250 eceleni noma esikhundleni sezinga le-IEC 60529 IP. Nakuba kukhona ukufana, lezi zindinganiso ezimbili azikwazi ukushintshaniswa ngokuphelele. Isilinganiso se-IP sesipikha sezimboni silinganisa ngokuqinile ukuvikelwa ezintweni eziqinile namanzi, kuyilapho izilinganiso ze-NEMA zethula ezinye izinto eziguquguqukayo zemvelo ezifana nokumelana nokugqwala, i-icing, kanye nokuphuma kwamafutha.

Isibonelo, isilinganiso se-NEMA 4X sivame ukubhekwa njengokulingana ne-IP66 maqondana nokuvikelwa kothuli namanzi. Kodwa-ke, u-“X” ku-NEMA 4X ubonisa ukumelana nokugqwala okuqinisekisiwe, ngokuvamile okudinga ukuthi indawo ebiyelwe isinde ekuhlolweni okuqinile kokufuthwa kukasawoti kwamahora angu-200. Isipikha se-IP66 esakhiwe ngepulasitiki ejwayelekile ye-ABS singahluleka indinganiso yokugqwala ye-NEMA 4X. Ngakho-ke, lapho kuqinisekiswa imininingwane yezindawo ezigqwala kakhulu, onjiniyela kumele babheke ngale kwesilinganiso se-IP futhi bacele izitifiketi ze-NEMA ezengeziwe noma imiphumela ethile yokuhlolwa kwenkungu kasawoti ye-ASTM B117.

Amafulegi Abomvu Ezicacisweni Zesipikha Esilinganiselwe yi-IP

Ngesikhathi senqubo yokubuyekezwa kwezincazelo, izimpawu eziningana ezibomvu zingabonisa ubunjiniyela obungaphansi kwezindinganiso noma ukumaketha okukhohlisayo mayelana nesilinganiso se-IP sesipikha sezimboni. Isibonakaliso esibomvu esivelele kakhulu sihilela izimangalo ze-IP68 ezingacacile. Ngokusho kwe-IEC 60529, ukujula nobude obuthile bokuhlolwa kokucwiliswa kwe-IP68 kumele kuchazwe umenzi, uma nje kuqine kakhulu kunezinga le-IP67 (imitha eli-1 imizuzu engama-30). Uma ishidi lezincazelo lithi “IP68″” kodwa lehluleka ukusho amapharamitha anjengokuthi “ukucwiliswa kumamitha ama-2 amahora angama-24,” isilinganiso asiphelele futhi asivumelekile.

Esinye isibonakaliso esibalulekile ukuba khona kwezinkinobho zomshini ezingavaliwe noma amabhlogo e-terminal avele esipikheni esibiza i-IP65 noma ngaphezulu. Izipikha zangempela ezingangeni manzi zisebenzisa izindlala zekhebula ezivaliwe kanye namakamelo e-terminal angaphakathi. Uma incwadi yokufaka idinga ukuthi umfakisi avule igumbi eliyinhloko le-acoustic ukuze axhume izintambo, isilinganiso se-IP yasefektri siyaphazamiseka ngesikhathi iyunithi ilungiswa ensimini. Izipikha zezimboni ezisezingeni eliphezulu zihlukanisa ibhokisi le-wiring junction esivalweni esikhulu se-transducer ukuze kulondolozwe uphawu lwemvelo.

Inqubo Yokukhetha Okokugcina Yezikhulumi Zezimboni

Ukukhethwa kokugcina kwesilinganiso se-IP sesipikha sezimboni kudinga indlela ephelele edlula nje ukukhetha inombolo ephezulu kakhulu etholakalayo. Abahlanganisi bezinhlelo kumele bahlanganise idatha yezemvelo, izidingo ze-acoustic, kanye nemikhawulo yesabelomali ukuze bachaze uhlelo lwe-PA lwesipikha olungangeni manzi olunikeza ukuqonda okuthembekile esikhathini eside sokusebenza.

Ukuthengwa kwezimpahla ngendlela ehlelekile akubheki isilinganiso se-IP njengencazelo yomshini nje kuphela, kodwa njengomshayeli oyinhloko we-Total Cost of Ownership (TCO) yesistimu. Inethiwekhi yezipikha ecacisiwe kahle inciphisa ukungenelela kokulungisa, inciphisa isikhathi sokungasebenzi, futhi iqinisekisa ukuthi ukuxhumana nokuphepha kokuphila kuhlala kusebenza ngezikhathi zemicimbi yesikhungo esibi kakhulu.

Indlela Yokulinganisela Indawo, Ukusebenza, kanye Nesabelomali

Isibonelo, i-aIsitifiketi se-ATEX, Isipikha se-horn sensimbi engagqwali esilinganiselwe yi-IP66 singase sibe nentengo ephezulu engu-40% kuya ku-60% kunemodeli ejwayelekile ye-aluminium ye-IP54. Kodwa-ke, ukusebenzisa imodeli ye-IP54 eshibhile endaweni enzima yokuwasha kuzoholela ekuhlulekeni okuphindaphindiwe.

Izindleko zangempela zesipikha esithintekile azihlanganisi nje kuphela ihadiwe yokufaka esikhundleni kodwa futhi nomsebenzi okhethekile odingekayo ekunakekelweni kwezimboni—ngokuvamile okubandakanya i-scaffolding, ama-lift akhethekile, kanye nokuvalwa kwendawo yesikhashana. Ngokutshala imali engu-60% ye-premium kusengaphambili ukuze uthole isilinganiso esifanele se-IP66, izikhungo zivame ukunciphisa izindleko zazo zokulungisa ngaphezu kuka-80% kuyo yonke iminyaka emihlanu yokuphila, okuvumela kalula ukusetshenziswa kwemali yokuqala ngenkathi kuqinisekiswa ukusebenza kohlelo lwe-PA okungaphazamiseki.

Nini Ukucacisa Isilinganiso Esiphezulu se-IP

Nakuba ukufanisa ngokunembile izilinganiso ze-IP nezingozi zemvelo kuyindlela ejwayelekile, kunezimo ezithile lapho ukucacisa ngokweqile ngamabomu isilinganiso se-IP sesipikha sezimboni kuyisinqumo sobunjiniyela esingcono kakhulu. Esinye sezimo ezinjalo sihilela ukuguquguquka kwesakhiwo. Uma ukwakheka kwesitshalo kuvame ukulungiswa kabusha, ukucacisa izipikha ze-IP66 kuyo yonke indawo yokucubungula kuqinisekisa ukuthi imishini ihlala ivikelwe noma ngabe indawo eyomile iguqulwa okwesikhashana ibe yindawo yokuphatha uketshezi.

Ukucacisa ngokweqile kusebenza futhi njengesilinganiso esibalulekile sokuphepha kwezehlakalo zesimo sezulu esibi kakhulu. Ezindaweni zezimboni ezisogwini, imvula ejwayelekile ingase idinge isilinganiso se-IP54 kuphela, kodwa usongo lwemvula enamandla esiphepho noma izikhukhula ezingalindelekile kwenza i-IP66 noma i-IP67 kube ukukhetha okuhlakaniphile. Ukunikeza lesi sivikelo kuqinisekisa ukuthi uhlelo lwesaziso esikhulu luyasinda ezigamekweni ezimbi kakhulu oluklanyelwe ukuxwayisa abasebenzi ngazo.

Izindlela Zokuphila Zokuthembeka Kwesikhathi Eside

Umgomo wokugcina wokucacisa isilinganiso se-IP sesipikha sezimboni esinembile ukukhulisa ukuthembeka kwesikhathi eside. Lapho behlola ihadiwe, onjiniyela kufanele babhekisele isilinganiso se-IP nesilinganiso se-Mean Time Between Failures (MTBF) esishiwo ngumenzi. Isipikha esilinganiselwe i-IP esishiwo kahle, esibekwe endaweni ehambisana nemikhawulo yaso yokuhlola, kufanele sifinyelele i-MTBF engaphezu kwamahora angu-50,000.

Ukuqinisekisa ukuthi lo mjikelezo wokuphila uyafezeka, abaphathi bezikhungo kumele basebenzise izinqubo zokufaka nokulungisa ezijwayelekile. Lokhu kuhlanganisa ukusebenzisa amathuluzi alawulwa yi-torque ukuvikela amabhawodi okuvala ngaphandle kokuchoboza ama-gasket avikela isimo sezulu, ukuhlola izihibe zekhebula ukuze kuvinjelwe amanzi ukuthi angangeni ezindlini zokungena, kanye nokwenza ukuhlolwa okubonakalayo kwaminyaka yonke kwe-acoustic mesh. Ngokuhlanganisa ukuqinisekiswa kwesilinganiso se-IP okuqinile nokuphathwa komjikelezo wokuphila okuhlelekile, izikhungo zezimboni zingasebenzisa izinhlelo ze-PA ze-loudspeaker ezingangeni manzi ezihlinzeka ngamashumi eminyaka okuxhumana okungenaphutha nokusindisa impilo.

Izinto Ezibalulekile Okufanele Uzicabangele

• Sebenzisa isilinganiso se-IP njengencazelo eyinhloko lapho ukhetha izipikha zezimboni zezindawo ezinothuli, ezinomswakama, ezingaphandle, noma ezihlanza amanzi.
• Hlola indawo ngayinye yesitshalo ngokwehlukana ngoba amakamelo okulawula, izindawo zokulayisha, phansi kokucubungula, kanye nezindawo zangaphandle zivame ukudinga amazinga ahlukene okuvikela.
• Cacisa izikhulumi ezingangeni manzi ezinesilinganiso se-IP esiphezulu lapho amajethi amanzi aqondile, umswakama ophezulu, ukugqwala, noma izinhlayiya eziphuma emoyeni zingabangela ukwehluleka kohlelo.
• Izipikha ezilinganiswe kahle nge-IP zinganciphisa ingozi yokwehluleka kwemvelo futhi zithuthukise isikhathi sokusebenza kwesistimu ye-PA eminyakeni eminingi.
• Ukuze uthole izimemezelo zokuphepha kokuphila kanye nemiyalezo yokuphuma, beka phambili ukuqina kwemvelo njengokumbozwa kwezwi kanye nokuzwakala.

imibuzo ejwayelekile ukubuzwa

Kusho ukuthini isilinganiso se-IP sesipikha sezimboni?

Isilinganiso se-IP sibonisa ukuthi isipikha esivalekile simelana kahle kangakanani nezinto eziqinile kanye noketshezi. Inombolo yokuqala ihlanganisa ukuvikelwa kothuli, kanti eyesibili ihlanganisa ukuvikelwa kwamanzi. Kumasistimu e-PA ezimboni, lokhu kusiza onjiniyela ukuthi bafanise izipikha nezimo ezinothuli, ezimanzi, zangaphandle, noma ezihlanza amanzi.

Yisiphi isilinganiso se-IP esingcono kakhulu kuma-loudspeaker angangeni manzi?

Ezindaweni zezimboni ezimanzi noma ezingaphandle, i-IP65 ivame ukuba yisisekelo ngoba imelana nothuli namanzi. Uma kugezwa ngamanzi ngomfutho ophezulu noma kutholakala kakhulu, i-IP66, i-IP67, noma ngaphezulu kungadingeka kuye ngezindlela zokuhlanza, ingozi yokucwiliswa, kanye nezimo zendawo.

Kungani izikhulumi ezinesilinganiso se-IP zibalulekile ezinhlelweni ze-PA eziphuthumayo?

Izinhlelo ze-PA eziphuthumayo kumele zisebenze ngesikhathi sama-alamu, ukuphuma kwabantu, kanye nezigameko zokusebenza. Uthuli, umswakama, ukugqwala, kanye nomswakama kungalimaza izikhulumi ezingakalwanga, kunciphisa ukuzwakala noma kubangele ukwehluleka. Izikhulumi ezikalwa nge-IP ezifanele zithuthukisa isikhathi sokusebenza futhi zinciphise ingozi yokulungisa ezindaweni ezinzima.

Ingabe zonke izindawo zesitshalo zidinga isilinganiso se-IP sesipikha esifanayo?

Cha. Amakamelo okulawula angadinga ukuvikelwa okuphansi, kuyilapho izindawo zokulayisha, izitezi zokucubungula, izindawo zasolwandle, kanye nezindawo zamakhemikhali zidinga izikhulumi ezinezinga eliphezulu. Ukuhlolwa kwendawo ngendawo kusiza ukulawula izindleko ngenkathi kugcinwa ukuxhumana okubalulekile kuthembekile.

Umswakama ungathinta kanjani izikhulumi ze-PA zezimboni?

Umswakama ophezulu ungalimaza othintana nabo, ubuthakathaka amakhoni esipikha, futhi ubangele amaphutha kagesi. Ezindaweni lapho umswakama ojwayelekile uvame ukudlula u-70%, izipikha ezingakalwanga kahle zingase zihluleke ngokushesha kakhulu kunamamodeli angangeni manzi achazwe kahle.
