Ubona i-“PVC” ne-“uPVC” kuma-spec sheet futhi kubonakala sengathi ziyashintshana. Lokhu kudideka kungaholela eku-odeni izinto ezingalungile zephrojekthi ebalulekile, okungafaka engcupheni ukwehluleka kwesistimu okubizayo.

Kumapayipi, izinto zokufaka, namavalvu, i-uPVC (Unplasticized Polyvinyl Chloride) ingcono ngoba iqinile futhi iqinile. I-PVC yigama elijwayelekile, kodwa ivame ukubhekisela kupulasitiki eguquguqukayo engafanele ukusetshenziswa kwengcindezi.

Lokhu kungenye yezinto ezivame kakhulu ukudideka embonini yethu, futhi kubaluleke kakhulu. Lapho ngikhuluma nabalingani bami abanjengoDumisani eNingizimu Afrika, ngihlala ngigcizelela ukubaluleka kolimi olucacile. Iqiniso liwukuthi, abantu abaningi embonini bathi “PVC” kanti empeleni basho ukuthi “uPVC.” Njengomkhiqizi, ngikholwa ukuthi kungumthwalo wami ukucacisa lokhu. Ukuqonda lo mehluko olula kusiza uDumisani ukuqondisa amakhasimende akhe ukuba enze ukukhetha okufanele, aqinisekise ukuthi yonke iphrojekthi iphephile futhi iyaphumelela. Ake sikuchaze.

Ingabe i-uPVC ibiza kakhulu kune-PVC?

Usebenza ngesabelomali esincane. Udinga ukwazi ukuthi ukukhetha i-uPVC kuzokhulisa kakhulu izindleko zephrojekthi, noma ukuthi umehluko wentengo mncane kakhulu ukuthi ukhathazeke ngawo.

Izinto zokusetshenziswa ze-uPVC eqinile kanye ne-PVC eguquguqukayo zinezindleko ezifanayo kakhulu. Intengo yomkhiqizo incike kakhulu kwikhwalithi, ukujiya kodonga, kanye nedumela lomkhiqizo kunomehluko phakathi kwe-“uPVC” kanye ne-“PVC”.

Lo mbuzo uncike ekutheni yini enquma izindleko zokugcina zevalvu noma ukufakelwa. Akukhona mayelana no-“u” ku-uPVC. I-polymer eyisisekelo iyafana. Izindleko zangempela yizoikhwalithi yezithakokanyeinqubo yokukhiqizaIvalvu "eshibhile" ishibhile ngesizathu esithile, futhi ayinalutho oluhlobene nohlobo lwe-PVC esetshenziswayo.

Izindleko Zezinto Ezibalulekile vs. Izindleko Zomkhiqizo

Kwa-Pntek, wonke ama-valve ethu okucindezela kanyeizinto zokufakazenziwe nge-uPVC. Uma ubona umehluko wentengo phakathi komkhiqizo wethu kanye nenye indlela eshibhile, kungenxa yalezi zici, hhayi ngenxa yezinto eziyisisekelo ngokwazo.

Intengo Ethinta Izinto	Inketho Ejwayelekile Eshibhile	Inketho ye-Pntek Esezingeni Eliphezulu
Umthombo Wezinto Ezingavuthiwe	Izinto zokugcwalisa noma ze-resin ezisetshenziswe kabusha	I-resin engu-100% ye-Virgin uPVC
Izithasiselo Ezivikelayo	Iziqinisi ze-UV ezisezingeni eliphansi noma ezingenazo nhlobo	Iziguquli ze-UV ezisezingeni eliphezulu kanye nethonya
Ubukhulu Bodonga	Izindonga ezincane (isilinganiso sokucindezela okuphansi)	Izindonga ezijiyile (isb., Ishejuli 40/80)
Ikhwalithi yokulawula	Ukuhlolwa okuncane, ukwakheka okungahambisani	Ukukhiqizwa okuzenzakalelayo, ukuhlolwa okuqinile kobukhulu

Ngakho-ke, ivalvu ye-uPVC esezingeni eliphezulu ingase ibize kakhulu kunevalvu esezingeni eliphansi eyenziwe nge-uPVC. Umbuzo kumthengi onjengoDumisani awuphathelene ne-uPVC uma kuqhathaniswa ne-PVC, kodwa umayelana nekhwalithi uma kuqhathaniswa nentengo ephansi.

Yikuphi okungcono, i-uPVC noma i-PVC?

Kumelwe ukhethe izinto ezifanele zombhobho wamanzi. Ukukhetha okukodwa kuholela ohlelweni oluqinile noluhlala isikhathi eside, kanti okunye kungabangela ukuvuza, ukwanda, kanye nokwehluleka ekugcineni.

Ngokusebenzisa ingcindezi njengamapayipi nama-valve, i-uPVC iyindlela engcono nefanele. Ukuqina kwayo kubalulekile ekulawuleni ingcindezi. I-PVC eguquguqukayo ingcono kuphela uma udinga umkhiqizo ukuthi ugobe, njengepayipi.

Ukuthi enye “ingcono” kufana nokubuza ukuthi isando singcono yini kunesikulufo. Zingamathuluzi ahlukene emisebenzi ehlukene. Ukudideka kukhona ngoba amagama afana kakhulu. Igama elithi “u” ku-uPVC limelela okungafakwanga ipulasitiki. Lokhu kusho ukuthi asizange sifake amakhemikhali abizwa ngokuthi ama-plasticizer. Ngaphandle kwawo, izinto zokwakha ziqinile futhi ziqinile.

Ithuluzi Elifanele Lomsebenzi

Uma ufaka ama-plasticizer, uthola i-PVC eguquguqukayo. Lokhu kusetshenziselwa izinto ezidinga ukugoba. Kunoma yiluphi uhlelo olubamba umfutho wamanzi futhi oludinga ukugcina isimo salo,i-uPVCyiyona ndlela kuphela.

Isicelo	Izinto Ezinhle Kakhulu	Kungani Kungcono
Umzila Omkhulu Wamanzi	i-uPVC	Amandla ayo nokuqina kwayo kuyadingeka ukuze kulawulwe ingcindezi ngaphandle kokukhula noma ukuqhuma.
Ipayipi Lengadi	I-PVC eguquguqukayo	Ukuguquguquka kuyimfuneko ebalulekile. Ipayipi eliqinile ngeke lisize ngalutho.
Umzimba we-Ball Valve	i-uPVC	Kumelwe igcine isimo sayo esiqondile ngaphansi kwengcindezi ukuqinisekisa ukuthi ibhola langaphakathi nezihlalo ziqina kahle.
Ukugqoka Intambo Kagesi	I-PVC eguquguqukayo	Kudingeka igobe kalula emakhoneni ngenkathi ifaka umswakama wentambo yethusi ngaphakathi.

Kumakhasimende kaDumisani angabakhi nabakhi, impendulo ilula: udinga i-uPVC yawo wonke amapayipi akho, izinto zokufaka, nama-valve. Kwa-Pntek, yilokho esikukhethekile kukho—imikhiqizo ye-uPVC yezinga eliphezulu yokuphathwa kwamanzi.

Yiziphi izinkinga zamapayipi e-uPVC?

Uncoma i-upVC yephrojekthi enkulu. Ukuze ugweme izinkinga zesikhathi esizayo futhi ulondoloze idumela lakho, udinga ukwethembeka ngobuthakathaka kanye nokulinganiselwa kwezinto ngaphambi kokuba umsebenzi uqale.

Izinkinga ezinkulu ze-uPVC ukubuthaka emazingeni okushisa abandayo kanye nokuwohloka ngenxa yokuvezwa yi-UV (ekukhanyeni kwelanga) isikhathi eside. Ayikwazi futhi ukusetshenziselwa amanzi ashisayo, njengoba ithambisa futhi ilahlekelwa yisilinganiso sayo sokucindezela.

Akukho mpahla ephelele, futhi umhlinzeki omuhle uhlala ethembekile ngemikhawulo yomkhiqizo. Ukwethembana kwakhelwe ekubonakaleni. Nakuba i-uPVC iyinto emangalisayo, kubalulekile ukwazi ukuthi akufanele isetshenziswe kuphi, nokuthi ungayivikela kanjani.

Ukuqonda Ukulinganiselwa kwe-uPVC

Nazi izinto ezintathu okufanele uzicabangele:

1. Ukucasuka Okuphansi Kwezinga Lokushisa:Ezimweni zokuqandisa, ipayipi noma ivalvu ye-upVC ingaba buthakathaka. Ukushaya okukhulu okuvela efosholweni noma emotweni kungabangela ukuthi iqhekeke. Lokhu akukhathazi kangako esimweni sezulu esifudumele njenge-Indonesia, kodwa yingakho izinhlelo ezindaweni ezibandayo kumele zingcwatshwe ngaphansi komgqa weqhwa noma zigcinwe ebusika ngendlela efanele.
2. Ukuzwela kwe-UV:Lesi yisici esibaluleke kakhulu sokufakwa kwangaphandle. Ukuchayeka ngqo elangeni isikhathi eside kuzophula i-uPVC. Iba nombala oshintsha umbala futhi iqhekeke. Ngenxa yalesi sizathu, amapayipi angaphandle kufanele apendwe ngopende we-latex osekelwe emanzini noma agqitshwe. Sifaka izithibi ze-UV efomini yethu ukuze sinciphise le nqubo, kodwa ukuvikelwa ngokomzimba kuhlale kuyindlela engcono kakhulu yesikhathi eside.
3. Imikhawulo Yokushisa:I-upVC ejwayelekile (Ishejuli 40/80) akufanele isetshenziswe emigqeni yamanzi ashisayo. Izinto ziqala ukuthamba ngaphezu kuka-140°F (60°C). Njengoba ithamba, ilahlekelwa ikhono layo lokubamba ingcindezi. Kumanzi ashisayo, ipulasitiki efanele ukusetshenziswa yi-CPVC (Chlorinated Polyvinyl Chloride).

Ingabe i-PVC ecindezelwe kakhulu ingcono kune-uPVC?

Ubona amagama anjengokuthi “Shejula u-80″ noma “i-PVC enomfutho ophezulu.” Uzibuza ukuthi lokhu kuyinto entsha, eqinile yini ehlukile ku-uPVC osuvele uyijwayele.

Igama elithi “i-PVC enomfutho ophezulu” limane nje lisho ipayipi le-uPVC elinodonga olujiyile, ngokuvamile iShejuli 80. Akuyona into ehlukile. Liseyi-uPVC, kodwa ukujiya kwalo okwengeziwe kuyivumela ukuthi ikwazi ukusingatha ukucindezeleka okuphezulu kwangaphakathi.

Lokhu kungenye imbangela yokudideka okukhulu emakethe. I-“PVC enomfutho ophezulu” kanye ne-“uPVC” akuzona izinto ezimbili ezihlukene ongakhetha kuzo. Ipayipi enomfutho ophezulu yenziwe nge-uPVC. Amandla okusingatha umfutho anqunywa ubukhulu bodonga. Imboni isebenzisa inombolo ethi “Schedule” ukuchaza lokhu.

Isilinganiso Sokucindezela Simayelana Nobukhulu, Hhayi Izinto Ezibonakalayo

Womabili amapayipi e-Schedule 40 kanye ne-Schedule 80 enziwe ngezinto ezifanayo ze-uPVC. Umehluko kuphela inani lezinto ezisetshenzisiwe. Cabanga ngakho njengebhokisi lekhadibhodi elincane uma kuqhathaniswa nelibanzi; womabili ayikhadibhodi, kodwa elilodwa liqine kakhulu.

Isici	Isheduli 40 uPVC	Ishejuli 80 uPVC (“Ukucindezela Okuphezulu”)
Uhlobo Lwezinto	i-uPVC	i-uPVC (into efanayo ncamashi)
Ubukhulu Bodonga	Okuncane kakhulu	Okukhulu
Isilinganiso Sokucindezela	Ngaphansi	Okuphakeme
Umbala Ovamile	Okumhlophe	Okumpunga Okumnyama
Ukusetshenziswa Okuyinhloko	I-DWV yokuhlala, ukunisela ngomfutho ophansi	Imigqa yenqubo yezimboni, imigudu emikhulu yokucindezela okuphezulu

Uma iklayenti licela uDumisani ukuthi alethe “i-PVC enomfutho ophezulu,” empeleni lisuke licela njeIsheduli 80 uPVC. "Kungcono" kuphela uma ingcindezi yohlelo lokusebenza ifuna lokho. Ukusebenzisa i-Sch 80 laphoI-Sch 40kwanele kuphephile, kodwa futhi kubiza ngokungadingekile.

Isiphetho

I-uPVC iyinto eqinile neqinile efanelekile kumapayipi okucindezela kanyeamavalvuNakuba ngokuvamile kubizwa ngokuthi “i-PVC”, ukuqonda ukuthi i-uPVC iyisinqumo esifanele kususa ukudideka futhi kuqinisekisa ukuthembeka kohlelo.
