Polyvinyl chloride (PVC) o se polymer o le vinyl chloride monomer (VCM) na faʻamalosia e le peroxide, azo compound ma isi tagata na amataina poʻo le maua fua i le faʻaaogaina o le polymerization i lalo o le gaioiga o le malamalama ma le vevela. Vinyl chloride homo polymer ma le vinyl chloride co polymer ua taʻua o le vinyl chloride resin.
O le PVC sa avea ma lapoʻa lautele-faʻamoemoe lautele i le lalolagi ma sa lautele faʻaaogaina. E lautele faʻaaogaina i mea fau fale, oloa gaosi oloa, manaʻoga i aso uma, fola paʻu, foloa poloka, paʻu faʻafoliga, paipa, uaea ma uaea, afifiina ata, fagu, foaming mea, faʻamau faʻamaumauga, alava ma isi.
O le PVC e leai se uiga ole paʻepaʻe paʻepaʻe, e maualalo le tulaga faʻapipiʻi. O lona vevela tioata suiga o 77 ~ 90 ℃, ma amata ona pala i le170 ℃. I le taimi nei e leaga le mautu o le malamalama ma le vevela: o le a faʻaleagaina ma maua hydrogen chloride i luga atu o le 100 ℃ pe a maeʻa se taimi umi o le la faʻaalia, ma atili ai ona otometi catalytic tuʻufaʻatasia, lea e mafua ai ona suia le lanu ma le paʻu i mea faʻaletino ma masini, I faʻaoga aoga , stabilizer poʻo isi mea faʻaopopo e tatau ona faʻaopopo e faʻaleleia atili ai le mautu o le PVC.
E mafai e le kamupani ona ofa i lalo atu o le PVC foaming additives:
| Faʻavasegaina | Oloa | CAS | ITUAIGA COUNTER | TALOSAGA |
| FAʻAALIGA | YIHOO AN245DW | 36443-68-2 35% 7732-18-5 65% | SONOX 2450DW | Faʻaoga tele ile styrene, synthetic rubber, POM homopolymer ma copolymer, PU, PA, PET, MBS, ma le PVC. |
| YIHOO AN333 | 77745-66-5 | JP333E | Phenol-leai ni vailaʻau, faʻaaogaina o fesoasoani fesoasoani faʻamautu i le PVC, faʻaleleia atili le lanu ma le malamalama o oloa a le PVC. E mafai foi ona faʻaaogaina i mea paʻu ma PU e faʻaleleia ai le teteʻeina o oloa i le matua. | |
| YIHOO HP136 | 181314-48-7 | E mafai ona faʻaavanoaina hydrogen olaola e toe faʻafou poloka phenolic antioxidant ma faʻaititia le faʻaopoopo faʻaopoopo o le lua AOs. Fetaui lelei mo maualuga vevela gaosi talosaga, PP, BOPP membrane mea, PC manino mea toe gaosia, polymer styrene, mea paipa PPR, TPU, pipiʻi, ma isi |
Ina ia maua polymer faʻaopoopoga i sili faʻapitoa talosaga, ua faʻatuina e le kamupani se oloa faʻasologa aofia ai lalo talosaga: PA polymerization & fesuiaiga faʻaopoopoga, PU foaming faʻaopoopoga, PVC polymerization & fesuiaʻi faʻaopoopoga, PC faʻaopoopoga, TPU elastomer faʻaopoopoga, maualalo VOC taʻavale teuteu faʻaopoopo mea teuteu ie sooupu faʻaopoopoga, ufiufi faʻaopoopoga, vali teuteu, API ma isi vailaʻau vailaʻau pei o le zeolite ma isi.
E masani lava ona e taliaina e faʻafesoʻotaʻi mai matou mo ni fesili!
