Mu gihe cyo gushyira pulasitiki mu buryo bwa pulasitiki, ibintu bitera imbaraga za calcium zinc bigira electronegativity nyinshi, kandi utudomo twinshi twa PVC resin dufite ubwinshi runaka, bigatuma habaho imbaraga zikomeye zo guhuza.
Ibikoresho bikomeza umunyu bya kalisiyumu bishobora kugabanywamo ibikoresho bikomeza umunyu bya kalisiyumu n'ibikomeza umunyu bya kalisiyumu
Ikoreshwa rya calcium zinc stabilizer rijyanye na resins na plasticizers, rifite ubwisanzure bwiza, imvura nke, ingano nto, kandi ryoroshye gukoresha. Ingaruka mbi nyamukuru ni amavuta make no kwangirika mu gihe bibitswe igihe kirekire.
Ibikoresho bikomeza kalisiyumu zinc bikomeye bigizwe ahanini n'isabune ya aside stearic. Iki gicuruzwa kirangwa n'amavuta meza kandi kibereye gutunganya imiyoboro ikomeye ya PVC n'imiterere yayo.
Ibicuruzwa bitunganywa hakoreshejwe ikoranabuhanga rya microemulsification bitsinda ingorane zavuzwe haruguru. Ibande ku kunoza ibintu bibiri: guhindura ibara rya mbere, gukoresha isabune ya zinc ihagije, no gukoresha ikintu gihuza kugira ngo zinc chloride igire ingaruka mbi, ikaba ubwoko bwinshi bwa zinc; Kugabanya ingano y'isabune ya zinc kugira ngo wirinde gutwika kwa zinc no guhindura ibara rya mbere ukoresheje inyongera bizwi nka low zinc blending. Ntabwo ikoreshwa cyane mu bicuruzwa byoroshye gusa, ahubwo ikoreshwa no mu gutunganya ibikomoka ku bimera bikomeye.
Ibikoresho bikomeza calcium zinc, bitewe n’uburyo bikoresha electronegativity nyinshi, bifite ubufatanye bwihariye ku ngingo zikomeye za resin ya PVC mu gihe cyo gukora plasticization, bigakora complexes zikomeye z’ingufu zihuza ibyuma bigabanya cyangwa bigakemura gukurura imigozi ya ion mu byiciro bitandukanye bya PVC. Ibi bituma ibice bihuza bya PVC byoroha gukwirakwira, kandi amatsinda ya molekile ashobora kugera ku mipaka mito, ibyo bikaba ingirakamaro mu gukora plasticization ya resin ya PVC. Bitera kwiyongera gukabije k’umuvuduko wo gushonga, bigashonga.
Ubushyuhe bw'umubiri buragabanuka, ubushyuhe buriyongera, kandi ubushyuhe bwo gushyira plastike buragabanuka.
Byongeye kandi, kubera ko ibikoresho bisanzwe byo gutunganya PVC byagenewe gutunganywa hakoreshejwe ibikoresho bigabanya umunyu, nubwo hongewemo amavuta ahagije, ntibishobora kubuza resin gukomeza gushonga mu gihe gihagije, bigahungabanya uburinganire bw'amavuta ya mbere. Mu cyiciro cya nyuma cyo gukoreshwa, PVC ishonga ikoresha ingano nini ya lisansi igabanya ubushyuhe mu cyiciro cya homogenization, ariko icyarimwe ntishobora kugera ku bushyuhe n'ubukonje bukwiye kugira ngo ihuze n'ibyo PVC ikomeye ikeneye mu gukora.
