Imathiriyeli ekrwada yokulungiselela umbhobho oqinileyo wePVC owenziwe ngamacangci amabini
Imathiriyeli ekrwada yokulungiselela umbhobho wePVC oqinileyo wodonga olumbini,
Imathiriyeli ekrwada yokuvelisa umbhobho wePVC owenziwe ngamacangci amabini,
I-Polyvinyl Chloride (i-PVC) yi-resin ye-thermoplastic ehambelanayo eyenziwa yi-polymerization ye-vinyl chloride monomer.Ngenxa yomahluko wemathiriyeli ekrwada, kukho iindlela ezimbini zokwenza i-vinyl chloride monomer calcium carbide inkqubo kunye nenkqubo yepetroleum.I-Sinopec PVC ithatha inkqubo yokunqunyanyiswa kabini, ngokulandelelana kwiNkampani yeMichiza yeShin-Etsu kunye neNkampani ye-Oxy Vinyls yaseMelika.Imveliso inokumelana nokugqwala kweekhemikhali, ipropathi egqwesileyo yokugquma umbane kunye nokuzinza okuhle kweekhemikhali.Ngomxholo ophezulu we-chlorine, izinto eziphathekayo zinokutshatyalaliswa komlilo okulungileyo kunye neempawu zokuzicima.I-PVC kulula ukuyiqhuba nge-extrusion, isitofu sokubumba, i-calendering, ukubunjwa kokuvuthela, ukuxinzelela, ukubumba kunye nokubumba kwe-thermal, njl.
Isicelo
I-PVC yenye yezona zinto zisetyenziswa kakhulu kwi-thermoplastic resins.Ingasetyenziselwa ukwenza iimveliso ezinobunzima obuphezulu kunye namandla, njengemibhobho kunye nokufakelwa, iingcango zeprofayili, iifestile kunye namaphepha okupakisha.
Isenokwenza iimveliso ezithambileyo, ezinje ngeefilimu, amaphepha, iingcingo zombane kunye neentambo, iibhodi eziphantsi komhlaba kunye nesikhumba sokwenziwa, ngokongezwa kweeplasticizers.

Imathiriyeli ekrwada esetyenziselwa ukwenza umbhobho oqinileyo wePVC ulungiswa ukusuka
I-PVC (100 pts.wt.),
i-trisalt (6.4-6.8 pts.wt.),
inqanaba elikhokelayo (0.42-0.47 pts.wt.),
i-barium stearate (1.4-1.7 pts.wt.),
iasidi stearic (0.42-0.47 pts.wt.),
iparafini ye-microcrystal (0.36-0.41 pts.wt.),
polyvinyl wax (0.58-0.62 pts.wt.),
I-ACR (401) (1.9-2.1 pts.wt.),
ipolyethylene eneklorini (5.8-6.3 pts.wt.),
superfine calcium carbonate (9-11 pts.wt.)
AC 316 (0.28-0.33 pts.wt.).
Iingenelo zayo kukusebenza okuphezulu kokuthambisa, amandla empembelelo, ukuqina kweringi kunye neTemp yokuthambisa yeVicat, indalo entle yokudiliza, kunye neplastikhi ebalaseleyo yobushushu obuphantsi.
