Ngokuyinhloko asetshenziselwa ukwenza iminyango kanye nezinto zokonga amawindi kanye nezinto zokonga amandla, futhi ivolumu yabo yesicelo isakhula kakhulu ezweni lonke. Emazweni athuthukile, isabelo semakethe seminyango yepulasitiki namafasitela futhi aphezulu kakhulu, njengama-50% eJalimane, ama-56% eFrance, kanye nama-45% e-United States.

Among the many PVC products, PVC pipes are the second largest consumption area, accounting for about 20% of its consumption. Ezweni lami, amapayipi e-PVC athuthukiswa ngaphambili kunamapayipi we-PE kanye namapayipi e-PP, anezinhlobonhlobo eziningi, ukusebenza okuningana, kanye nohlobo olunhlobonhlobo lwemakethe.

PVC consumption in the PVC film field ranks third, accounting for about 10%. Ngemuva kokuthi i-PVC ihlanganiswe nezithasiselo kanye neplasitiki, i-callender ekhipha ama-3 The film is processed in this way to become a calendered film. It can also be processed into packaging bags, raincoats, tablecloths, curtains, inflatable toys, etc. by cutting and heat sealing. Wide transparent films can be used for greenhouses, plastic greenhouses and ground films. The biaxially stretched film can be used for shrink packaging due to its heat shrinkage characteristics.

Add stabilizers, lubricants and fillers to PVC. Ngemuva kokuxuba, i-extruder ingakhipha ama-calibers ahlukahlukene amapayipi anzima, amapayipi akhethekile, namapayipi ahlanganisiwe, asetshenziswa njengamapayipi wendle, amapayipi amanzi okuphuza, ama-stair anderrails noma izitebhisi zezitayela noma izitebhisi zezitebhisi noma izitebhisi zensimbi. The rolled sheets are overlapped and hot pressed to make hard sheets of various thicknesses. Amashidi angasikwa esakhiweni esidingekayo, bese kusetshenziselwa izinduku ze-welding ze-PVC zokuvula amathangi ahlukahlukene okugcina amelana namakhemikhali, ama-air ducts neziqukathi zomoya oshisayo.

Artificial leather with a backing is made by applying PVC paste on cloth or paper, and then plasticizing it at above 100°C. It can also be made by first calendering PVC and additives into a film, and then pressing it with a backing. Isikhumba sokufakelwa ngaphandle kokuxhaswa ngokusekelwa ngqo eshidini elithambile lobukhulu obuthile nge-calender, bese becindezela ngephethini. Isikhumba sokufakelwa singasetshenziswa ukwenza amasudi, izikhwama, isembozo sencwadi, ama-sofa kanye nezihlalo zesihlalo semoto, njll., Kanye nesikhumba esiphansi, esisetshenziswa njengento ephansi yezakhiwo.

Lapho i-PVC ethambile ixubene, inani elifanele lomenzeli we-foaming lingezwa ukwenza ishidi, elivezwe lube yi-foam plastic, olungasetshenziswa njengezinto zokufaka amagwebu, izimbadada, nezinto zokufaka ubufakazi bokushaqeka. Kungenziwa futhi kube amashidi aphansi anamagwebu ama-hard pvc kanye namaphrofayili asuselwa ku-extruder, angathatha isikhundla sokhuni futhi uhlobo olusha lwezinto zokwakha.

PVC is added with impact modifier and organic tin stabilizer, and becomes transparent sheet after mixing, plasticizing and calendering. Kungenziwa iziqukathi ezibunjiwe ezibunjiwe noma ezisetshenziselwa ukufakwa kwe-vacuum blister nge-thermoforming, futhi kuyinto enhle yokufaka impahla nokuhlobisa.
