Inkcazo:
I-Polyvinyl chloride, efinyeziweyo njenge-PVC S1000, i-polymer eyenziwe yi-polymerization ye-vinyl chloride monomer (VCM) phantsi kwesenzo.
yeeperoxides, iikhompawundi ze-azo kunye nabanye abaqalisi okanye phantsi kwesenzo sokukhanya kunye nobushushu ngokwendlela yokusabela ye-radical polymerization yasimahla.I-Vinyl chloride homopolymer kunye ne-vinyl chloride copolymer zibizwa ngokudibeneyo njenge-vinyl chloride Resin.I-PVC ngumgubo omhlophe kunye nesakhiwo se-amorphous kunye neqondo elincinci le-branching.Ubushushu beglasi yayo yokutshintsha yi-77~90℃, kwaye iqala ukubola malunga ne-170℃.Inozinzo olulambathayo ekukhanyeni nasekufudumeni.Ukubola kuvelisa i-hydrogen chloride, ethi iphinde i-autocatalyze kwaye ibole, ibangele ukubola, kunye nomzimba kunye noomatshini.
iipropati nazo ziyancipha ngokukhawuleza.Kwizicelo ezisebenzayo, i-stabilizers kufuneka yongezwe ukuphucula ukuzinza kubushushu nokukhanya.
I-PVC S1000 Isetyenziswa ikakhulu uku:
1. Iprofayile yePVC
Iiprofayili yindawo enkulu yokusetyenziswa kwePVC kwilizwe lam, ibalwa malunga ne-25% yokusetyenziswa kwePVC iyonke.Ikakhulu isetyenziselwa ukwenza iingcango kunye neefestile kunye nezixhobo zokugcina amandla, kwaye umthamo wabo wesicelo usakhula kakhulu kulo lonke ilizwe.Kumazwe athuthukileyo, isabelo semarike yeengcango zeplastiki kunye neefestile nazo ziphezulu, umzekelo, iJamani yi-50%, iFransi yi-56%, kunye ne-United States yi-45%.
2. Umbhobho we-Polyvinyl chloride
Phakathi kweemveliso ezininzi ze-polyvinyl chloride, iipayipi ze-polyvinyl chloride yindawo yesibini enkulu yokusetyenziswa, ibalwa malunga ne-20% yokusetyenziswa kwayo.Ezweni lam, imibhobho ye-polyvinyl chloride iphuhliswa kwangaphambili kunemibhobho ye-PE kunye nemibhobho ye-PP, eneentlobo ezininzi, ukusebenza kakuhle, kunye uluhlu olubanzi lwezicelo, kwaye zibambe indawo ebalulekileyo kwimarike.
3. Ifilimu yePolyvinyl chloride
Ukusetyenziswa kwe-PVC kwintsimi yefilimu ye-PVC ithatha indawo yesithathu, ibalwa malunga ne-10%.Emva kokuba i-PVC ixutywe kunye ne-additives kunye neplastiki, i-calender ye-three-roll okanye i-four-roll isetyenziselwa ukwenza ifilimu ecacileyo okanye enemibala enobunzima obuchaziweyo.Ifilimu icutshungulwa ngolu hlobo ukuze ibe yifilimu yekhalenda.Inokunqunyulwa kwaye itywinwe ngobushushu ukusetyenzwa kweengxowa zokupakisha, iidyasi zemvula, amalaphu etafile, iikhethini, iithoyi ezivuthekayo, njl njl.Ifilimu eyoluliweyo ye-biaxially ineempawu zokunciphisa ukushisa kwaye ingasetyenziselwa ukupakishwa kwe-shrink.
4. PVC izinto ezinzima kunye neepleyiti
I-stabilizers, i-lubricants kunye ne-fillers zongezwa kwi-PVC.Emva kokuxuba, i-extruder ingasetyenziselwa ukukhupha imibhobho enzima, imibhobho ekhethekileyo kunye nemibhobho edibeneyo yeendlela ezahlukeneyo, ezinokuthi zisetyenziswe njengemibhobho yogutyulo, imibhobho yamanzi okusela, i-wire casings okanye i-staircase handrails. ukwenza iipleyiti ezinzima ezahlukeneyo thicknesses.Ipleyiti inokusikwa kwimilo efunekayo, kwaye emva koko idityaniswe ngomoya oshushu kunye PVC intonga welding ukwenza iiitanki zokugcina imichiza ezahlukeneyo, imibhobho umoya kunye nezikhongozeli.
