Fa'aaliga 1: PVC malosi o se tasi o mea sili ona fa'aaogaina palasitika.PVC meafaitino o se mea e le fa'a'ai'ai.

Vaega 2: Stabilizers, lubricants, auxiliary process agents, pigments, anti-impact agents ma isi faʻaopoopoga e masani ona faʻaopoopoina i mea PVC i le faʻaaogaina moni.

Vaega 3: PVC mea e leai se mu, malosi maualuga, tetee tau ma sili ona lelei geometric mautu.

Vaega 4: O le PVC e malosi le teteʻe atu i mea faʻamaʻi, faʻaitiitia mea faʻapitoa ma malosi malosi.Ae ui i lea, e mafai ona pala e ala i vailaʻau faʻamaʻi faʻamaʻi e pei ole sulfuric acid faʻamaʻi ma faʻamaʻi nitric acid ma e le talafeagai mo le faʻafesoʻotaʻi ma vailaʻau manogi ma hydrocarbons chlorinated.

Faʻaaliga 5: O le vevela o le PVC i le taimi o le gaosiga o se faʻasologa taua tele.Afai e le talafeagai lenei parakalafa, o le a mafua ai le faʻafitauli o mea faʻaleagaina.

Vaega 6: O uiga tafe o le PVC e matua leaga lava, ma o lona faagasologa e matua vaapiapi.Aemaise lava le maualuga o le mamafa o le PVC meafaitino e sili atu ona faigata ona faʻaogaina (o lenei ituaiga o mea e masani ona manaʻomia e faʻaopopo ai le lubricant e faʻaleleia ai uiga tafe), o le mea lea e masani ona faʻaaogaina le mea PVC ma le mamafa mole mole.

Vaega 7: O le fua fa'aitiitia o le PVC e matua maualalo, masani 0.2 ~ 0.6%.

Polyvinyl chloride, fa'apu'upu'u o le PVC (Polyvinyl chloride) i le Igilisi, o se vinyl chloride monomer (VCM) i peroxyide, azo compounds ma isi initiators;pe i lalo o le gaioiga o le malamalama ma le vevela e tusa ai ma le free radical polymerization reaction mechanism Polymers faia e polymerization.Vinyl chloride homopolymer ma vinyl chloride copolymer o loʻo taʻua faʻatasi o le vinyl chloride resin.

PVC o se paʻepaʻe paʻepaʻe ma se fausaga amorphous.O le tikeri o le lala e laʻititi, o le vavalalata vavalalata e tusa ma le 1.4, o le vevela o le suiga o tioata e 77 ~ 90 ℃, ma e amata ona pala ile 170 ℃.O le mautu i le malamalama ma le vevela e leaga, i luga atu o le 100 ℃ pe a maeʻa se taimi umi.O le pa'u o le la o le a pala e maua ai le hydrogen chloride, lea o le a atili ai ona fa'atosina le pala, fa'apogai ai le liu, ma o mea fa'aletino ma masini o le a vave fa'aitiitia.I faʻaoga faʻaoga, e tatau ona faʻaopoopoina faʻamautu e faʻaleleia ai le mautu i le vevela ma le malamalama.

O le mamafa mole mole o le PVC gaosia e masani lava i le va o le 50,000 i le 110,000, faʻatasi ai ma le polydispersity tele, ma faʻateleina le mamafa o le mole i le faʻaitiitia o le vevela polymerization;e leai se mea faʻamautu faʻamau, amata ona faʻamalulu i le 80-85 ℃, ma avea viscoelastic i le 130 ℃, 160 ~ 180 ℃ amata ona liua i le tulaga vai viscous;o loʻo i ai mea faʻainisinia lelei, o le malosi faʻamalosi e tusa ma le 60MPa, o le malosi o le aʻafiaga o le 5 ~ 10kJ / m2, ma o loʻo i ai mea sili ona lelei dielectric.

O le PVC sa masani ona avea ma gaosiga sili ona tele a le lalolagi o palasitika faʻamoemoe lautele, ma e faʻaaogaina lautele.E faʻaaogaina lautele i mea faufale, oloa gaosi oloa, mea e manaʻomia i aso taʻitasi, paʻu fola, fola fola, paʻu faʻapitoa, paipa, uaea ma uaea, afifiina ata tifaga, fagu, mea faʻafefe, mea faʻamaufaʻailoga, filo, ma isi.

E fa'aoga lelei le matou falegaosimealimumeafaitino, e pei o 718, 718H, ma isi, mea faʻapipiʻi lelei, ola umi, ma oloa faʻaaogaina i mea faʻapipiʻi eseese e mafai ona maua ai oloa palasitika maualuga.
