Intshayelelo yemveliso:
I-PVC-U yokukhupha amanziumbhobhoisebenzisa i-polyvinyl chloride resin njengeyona nto iphambili ekrwada, yongeza izongezo eziyimfuneko, kwaye yenziwe ngokulungiswa kwe-extrusion. Luluhlu lweemveliso zombhobho wokuhambisa amanzi ngobuchwepheshe obuvuthiweyo kwaye isetyenziswe ngokubanzi ekhaya nakwamanye amazwe. Imveliso ineenzuzo zobomi obude, ukuxhathisa ukubola, njl., engenakulinganiswa nemibhobho yentsimbi; ikhaphukhaphu kulwakhiwo, kulula ukuyiphatha kunye nokuyifaka, kwaye kulula ukuyidibanisa. Isetyenziswa ngokubanzi kwimijelo yolwakhiwo lwabahlali, imisele yamanzi ekhemikhali, kunye nokuhambisa amanzi emvula.

Iimbonakalo:
Imveliso ineenzuzo zobomi obude obungenakulinganiswa kunye nokuchasana nokugqwala kwemibhobho yentsimbi; ikhaphukhaphu kulwakhiwo, kulula ukuyiphatha kunye nokuyifaka, kwaye kulula ukuyidibanisa. Isetyenziswa ngokubanzi kwimijelo yolwakhiwo lwabahlali, imisele yamanzi ekhemikhali, kunye nokuhambisa amanzi emvula.
1. Ukuqina komphezulu kunye namandla okuqina kombhobho zigqwesileyo, kunye nemeko yokhuselekoumbhobhoiphezulu.
2. Iindleko eziphantsi, ubomi benkonzo ende, ubomi benkonzo eqhelekileyo bunokufikelela ngaphezu kweminyaka engama-50, akukho mfuneko yokugcinwa rhoqo kunye nokulungiswa.
3. Umbhobho unokumelana ne-corrosion egqwesileyo kwi-asidi ye-inorganic, iialkali, kunye neetyuwa. Ifanelekile ukukhutshwa kwamanzi amashishini kunye nokuthutha. Ayina rusi okanye isikali, ngoko ke akuyi kubakho ukubola kunye nokuncipha ngaphakathi.
Akulula ukuvalelwa, kwaye udonga lwangaphandle aluyi kungcoliswa ngenxa yokurusaumbhobho, eqinisekisa ubuhle besakhiwo.
4. I-coefficient ye-friction yepayipi incinci, ukuhamba kwamanzi kuhamba kakuhle, akulula ukuvalelwa, kwaye umsebenzi wokulondoloza uncinci.
5. Izinto eziphathekayo zinesalathisi esiphezulu se-oksijini kwaye zizicima.
6. I-coefficient yokwandisa i-linear yombhobho incinci, kwaye inani le-deformation echaphazelekayo yiqondo lokushisa lincinci. I-conductivity ye-thermal kunye ne-elastic modulus incinci, kwaye ukusebenza kwe-anti-freezing kubhetele kunemibhobho yokukhupha isinyithi.
7. Imibhobho kunye nezixhobo zixhunywe ngeglue, indlela yokwakha ilula, ukusebenza kukulungele, kwaye ukufakwa komsebenzi wofakelo kuphezulu.
8. Ayinatyhefu, ayinazo iityuwa ezinetyhefu kunye nezinye iikhemikhali eziyityhefu, kwaye ayinabungozi kumzimba womntu.
