I-valve yonyawo lwe-PVC
I-PVCivalvu engezansiuhlobo lwevalvu yokonga amandla, evame ukufakwa ekugcineni kwephayiphi lokumunca ngaphansi kwamanzi lephayiphi lamanzi ukuze kuvinjelwe uketshezi olusephayiphini lephayiphi lamanzi ukuthi lungabuyeli emthonjeni wamanzi, ludlala umsebenzi wokungena kuphela kodwa lungaphumi. Kunezindawo eziningi zokungena amanzi kanye nezimbambo zokuqinisa esembozweni sevalvu, okungelula ukuzivimba. Ivalvu engezansi ilula ngesisindo futhi kulula ukuyifaka.
Izindlela zokuxhuma yilezi: uhlobo lokubopha, kanye nesakhiwo somkhiqizo: uhlobo lwebhola elintantayo. Ingasetshenziswa namaphampu ahlukahlukene e-centrifugal kanye namaphampu azibekela wona.
Lo mkhiqizo unesakhiwo esisha kanye nokusebenza kahle kokuvala. Ungamelana ne-asidi, i-alkali kanye nokugqwala. Isikhathi eside sokusetshenziswa. Usetshenziswa kabanzi embonini yamakhemikhali, i-fiber yamakhemikhali, i-chlor-alkali, amandla kagesi, imithi, izibulala-zinambuzane, udayi, ukuncibilikisa, ukudla, ukwelashwa kwendle, ukulima izinhlanzi zasolwandle, kanye neminye imboni.
I-PVC iyimpuphu emhlophe enesakhiwo esingaguquki. Izinga lokuhluma lincane, ubuningi obuhlobene bungaba ngu-1.4, izinga lokushisa lokushintsha kwengilazi lingu-77~90℃, futhi iqala ukubola cishe ku-170℃. Ayinawo ukuqina okuhle ekukhanyeni nasekushiseni, ngaphezu kuka-100℃ noma ngemva kwesikhathi eside. Ukuchayeka elangeni kuzobola ukuze kukhiqizwe i-hydrogen chloride, ezoqhubeka nokwenza ukubola kube ngokuzenzakalelayo, okubangela ukushintsha kombala, futhi izakhiwo zomzimba nezemishini nazo zizokwehla ngokushesha. Ezisetshenzisweni ezisebenzayo, kumele kufakwe iziqinisi ukuze kuthuthukiswe ukuqina kokushisa nokukhanya.
Izici
Izinto:I-PVC

2) Amelana nokushisa okuphezulu, amandla amahle omthelela
3) Ukufakwa okulula nokuthembekile, izindleko zokwakha eziphansi
4) Impahla enhle kakhulu yokuvimbela ukushisa kusukela ekuqhutshweni kokushisa okuncane
5) Ilula, kulula ukuyithutha nokuyiphatha, ilungele ukonga abasebenzi
6) Izindonga zangaphakathi ezibushelelezi zinciphisa ukulahleka kwengcindezi futhi zandise isivinini sokugeleza
7) Ukuvikela umsindo (kuncishiswe ngo-40% uma kuqhathaniswa namapayipi ensimbi agqitshiwe)
8) Imibala ekhanyayo kanye nomklamo omuhle kakhulu kuqinisekisa ukufaneleka kokubili ukufakwa okuveziwe nokufihliwe
9) Ingasetshenziswa kabusha, inobungani nemvelo, ihambisana nezindinganiso ze-GBM
10) Isikhathi eside kakhulu sokusetshenziswa okungenani iminyaka engama-50Izinto
