Uphawu loku-1: I-PVC engqongqo yenye yezona zinto zisetyenziswa kakhulu kwiplastiki.Izinto zePVC ziyinto engekho crystalline.

Uphawu lwesi-2: Izizinzi, izithambiso, ii-agent ezincedisayo, ii-pigments, i-anti-impact agents kunye nezinye izongezo zihlala zongezwa kwizinto ze-PVC ekusetyenzisweni ngokwenene.

Uphawu lwe-3: Izinto zePVC zinokutsha, amandla aphezulu, ukumelana nemozulu kunye nokuzinza kwejometri.

Uphawu lwesi-4: I-PVC inokuchasana okunamandla kwi-oxidants, ii-agent zokunciphisa kunye nee-acids ezinamandla.Nangona kunjalo, inokugqweswa yi-acids oxidizing concentrated efana ne-concentrated sulfuric acid kunye ne-nitric acid egxininisiweyo kwaye ayifanelekanga ukudibana ne-hydrocarbons enevumba elimnandi kunye ne-chlorinated hydrocarbons.

Uphawu lwe-5: Ubushushu obunyibilikayo bePVC ngexesha lokucubungula yinkqubo ebaluleke kakhulu ipharamitha.Ukuba le parameter ayifanelekanga, iya kubangela ingxaki yokubola kwezinto.

Uphawu lwe-6: Iimpawu zokuhamba kwePVC zihlupheke kakhulu, kwaye uluhlu lwenkqubo yalo luncinci kakhulu.Ngokukodwa i-molecular weight PVC material inzima kakhulu ukuqhubekeka (olu hlobo lwezinto eziphathekayo ludla ngokufuna ukongeza i-lubricant ukuphucula iimpawu zokuhamba), ngoko ke izinto ze-PVC ezinobunzima obuncinane be-molecular budla ngokusetyenziswa.

Uphawu lwesi-7: Izinga lokucutheka kwePVC lisezantsi kakhulu, ngokubanzi 0.2~0.6%.

I-Polyvinyl chloride, efinyeziweyo njenge-PVC (i-Polyvinyl chloride) ngesiNgesi, i-vinyl chloride monomer (VCM) kwi-peroxides, i-azo compounds kunye nabanye abaqalisi;okanye phantsi kwentshukumo yokukhanya kunye nobushushu ngokwendlela yokusabela ye-radical ye-polymerization yasimahla Iipolymers ezenziwe yi-polymerization.I-Vinyl chloride homopolymer kunye ne-vinyl chloride copolymer zibizwa ngokudibeneyo njenge-vinyl chloride resin.

I-PVC ngumgubo omhlophe kunye nesakhiwo se-amorphous.Iqondo le-branching lincinci, ukuxinana okuhambelanayo malunga ne-1.4, iqondo lokushisa leglasi liyi-77 ~ 90 ℃, kwaye liqala ukubola malunga ne-170 ℃.Uzinzo ekukhanyeni nakubushushu akulunganga, ngaphezu kwe-100℃ okanye emva kwexesha elide.Ukukhanya kwelanga kuya kubola ukuvelisa i-hydrogen chloride, eya kuthi iqhubele phambili i-autocatalyze ukubola, ibangele ukubola, kunye neempawu ezibonakalayo kunye nezomatshini nazo ziya kuncipha ngokukhawuleza.Kwizicelo ezisebenzayo, i-stabilizers kufuneka yongezwe ukuphucula ukuzinza kubushushu nokukhanya.

Ubunzima be-molecular ye-PVC eveliswe kwimizi-mveliso ngokubanzi kuluhlu lwe-50,000 ukuya kwi-110,000, kunye ne-polydispersity enkulu, kwaye ubunzima be-molecular buyanda ngokuhla kweqondo lokushisa kwe-polymerization;ayinayo indawo yokunyibilika esisigxina, iqala ukuthamba kwi-80-85℃, kwaye ibe yi-viscoelastic kwi-130℃, i-160～180℃ iqale ukuguquka ibe yimeko ye-viscous fluid;ineempawu ezilungileyo zoomatshini, amandla okuqina amalunga ne-60MPa, amandla empembelelo yi-5～10kJ/m2, kwaye ineempawu ezibalaseleyo zedielectric.

I-PVC yayiyeyona mveliso inkulu yehlabathi yeeplastiki zenjongo jikelele, kwaye isetyenziswa ngokubanzi.Isetyenziswa kakhulu kwizinto zokwakha, iimveliso zoshishino, iimfuno zemihla ngemihla, ngesikhumba somgangatho, iithayile zomgangatho, isikhumba sokwenziwa, imibhobho, iingcingo kunye neentambo, iifilimu zokupakisha, iibhotile, izinto ezinogwebu, izinto zokutywina, iifayili, njl.

Umzi-mveliso wethu usebenzisa okulungileyongundoizixhobo, ezifana 718, 718H, njalo njalo, izinto ngundo elungileyo, ubomi obude, kunye neemveliso ezisetyenziswa kwimathiriyeli zeplastiki ezahlukeneyo unokuvelisa iimveliso zeplastiki ezikumgangatho ophezulu.
