Uphawu 1: I-PVC eqinileyo yenye yezona zinto zeplastiki zisetyenziswa kakhulu. Izinto ze-PVC azinakristali.

Uphawu 2: Izinto ezizinzisa izinto, izinto zokuthambisa, izinto zokuncedisa ekusetyenzweni kwezinto, ii-pigment, izinto ezilwa nefuthe kunye nezinye izongezo zihlala zongezwa kwizinto zePVC xa zisetyenziswa ngokwenene.

Uphawu 3: Izinto ze-PVC azitshi, zinamandla aphezulu, ziyamelana nemozulu kwaye zizinzile kakhulu ngokwejometri.

Uphawu 4: I-PVC inokumelana okukhulu nee-oxidants, ii-reducing agents kunye nee-asidi ezinamandla. Nangona kunjalo, inokubola zii-asidi ze-oxidizing ezixineneyo ezifana ne-sulfuric acid exineneyo kunye ne-nitric acid exineneyo kwaye ayifanelekanga ukuba idibane nee-hydrocarbons ezinuka kamnandi kunye nee-hydrocarbons ezikhloriniweyo.

Uphawu 5: Ubushushu bokunyibilika kwePVC ngexesha lokucubungula yiparameter yenkqubo ebaluleke kakhulu. Ukuba le parameter ayifanelekanga, iya kubangela ingxaki yokubola kwezinto.

Uphawu 6: Iimpawu zokuhamba kwePVC zimbi kakhulu, kwaye uluhlu lwayo lwenkqubo luncinci kakhulu. Ingakumbi izinto zePVC ezinobunzima obukhulu beemolekyuli kunzima ukuzicubungula (olu hlobo lwezinto ludla ngokufuna ukongeza i-lubricant ukuphucula iimpawu zokuhamba), ngoko ke izinto zePVC ezinobunzima obuncinci beemolekyuli zihlala zisetyenziswa.

Uphawu 7: Izinga lokuncitshiswa kwePVC liphantsi kakhulu, ngokubanzi yi-0.2 ~ 0.6%.

I-Polyvinyl chloride, efinyeziweyo njenge-PVC (i-Polyvinyl chloride) ngesiNgesi, yi-vinyl chloride monomer (VCM) kwi-peroxides, kwi-azo compounds nakwezinye izinto eziqalisileyo; okanye phantsi kwesenzo sokukhanya nobushushu ngokwendlela yokusabela ye-free radical polymerization. Ii-Polymers ezenziwe yi-polymerization. I-homopolymer ye-vinyl chloride kunye ne-vinyl chloride copolymer zibizwa ngokuba yi-vinyl chloride resin.

I-PVC yipowder emhlophe enesakhiwo esingaguqukiyo. Iqondo lokuqhekeka lincinci, uxinano oluhambelanayo lumalunga ne-1.4, ubushushu bokutshintsha kweglasi yi-77~90℃, kwaye iqala ukubola malunga ne-170℃. Uzinzo ekukhanyeni nasekufudumaleni alulunganga, lungaphezulu kwe-100℃ okanye emva kwexesha elide. Ukuvezwa lilanga kuya kubola ukuze kuveliswe i-hydrogen chloride, eya kuthi ibangele ukubola ngokuzenzekelayo, ibangele ukutshintsha kombala, kwaye iimpawu zomzimba nezemishini nazo ziya kuncipha ngokukhawuleza. Kwiindlela ezisebenzayo, kufuneka kongezwe iziqinisi ukuphucula uzinzo ekufudumaleni nasekukhanyeni.

Ubunzima bemolekyuli yePVC eveliswa kwimizi-mveliso ngokubanzi buphakathi kwama-50,000 ukuya kuma-110,000, kunye ne-polydispersity enkulu, kwaye ubunzima bemolekyuli buyanda xa ubushushu bepolymerization buhla; ayinayo indawo yokunyibilika esisigxina, iqala ukuthamba kwi-80-85℃, kwaye iba yi-viscoelastic kwi-130℃, i-160 ~ 180℃ iqala ukuguquka ibe yimeko yolwelo oluxineneyo; ineempawu ezilungileyo zoomatshini, amandla okutsalwa amalunga ne-60MPa, amandla okubetha yi-5 ~ 10kJ/m2, kwaye ineempawu ezilungileyo ze-dielectric.

I-PVC yayiyeyona mveliso inkulu ehlabathini yeeplastiki ezisetyenziswa ngokubanzi, kwaye isetyenziswa kakhulu. Isetyenziswa kakhulu kwizixhobo zokwakha, kwiimveliso zoshishino, kwizinto ezifunekayo imihla ngemihla, kwisikhumba somgangatho, kwiithayile zomgangatho, kwisikhumba esenziwe ngokwenziwa, kwiipayipi, kwiingcingo nakwiintambo, kwiifilimu zokupakisha, kwiibhotile, kwizinto zokufaka igwebu, kwizinto zokuvala, kwiifayibha, njl.njl.

Umzi-mveliso wethu usebenzisa izinto ezilungileyoumngundoizixhobo, ezifana ne-718, 718H, njl.njl., izixhobo zokubumba ezilungileyo, ubomi obude, kunye neemveliso ezisetyenziswa kwizixhobo ezahlukeneyo zeplastiki zinokuvelisa iimveliso zeplastiki ezikumgangatho ophezulu.
