Itandukaniro riri hagati ya calcium zinc stabilizer na potassium salt stabilizer

1, Uburyo bw'ibikorwa
Iterambere rya zinc ya kalisiyumu: ribuza PVC kwangirika binyuze mu ngaruka zidasanzwe z'isabune ya kalisiyumu n'isabune ya zinc, mu gihe rikwiza umwuka wa HCl ukorwa no kwangirika kwa PVC. Gukomera kwayo bituruka ku ngaruka zivanze z'ibice byinshi (nk'ubutaka budasanzwe, hydrotalcite, nibindi), bishobora kubuza kwangirika kwa PVC na zinc iyons.
Ituma umunyu w’ibice by’umuhondo ukomeza kwiyongera: kwishingikiriza ku busharire bukomeye bwa Lewis bw’umunyu w’ibice by’umuhondo kugira ngo bihagarike HCl, no kubuza uburyo PVC chain decomposition reaction ihinduka binyuze mu kwimura atome za chlorine zidahindagurika.
2、 Ituze n'ubudahangarwa ku bidukikije
Ituze:
Ibikoresho bigabanya umunyu wa lead bifite ubushyuhe buhamye, bifite ibara ryiza, amavuta meza, kandi birwanya ikirere igihe kirekire.
Ubudahangarwa bw'ibikoresho bigabanya ubushyuhe bwa kalisiyumu mu ntangiriro ni buke, ariko ibintu bivanze nka kalisiyumu isanzwe yo mu butaka birushaho kunoza imikorere binyuze mu ngaruka zifatika, bikagera ku rwego rw'umunyu wa lead.
Kubungabunga ibidukikije:
Umunyu wa lead urimo lead ikoze mu byuma bikomeye, itera kwanduza ibidukikije n’ibyago ku buzima bw’abantu, kandi ntiyubahiriza amabwiriza agenga ibidukikije nka EU RoHS.
Ibikoresho bikomeza ubwiza bwa kalisiyumu ntabwo birimo ibyuma biremereye, byujuje ibisabwa mu bidukikije, kandi bifite ubudahangarwa ku ihumana rya sulfure (nk'uko bitahinduka umukara mu turere tw'imvura ya aside yo mu majyaruguru).
3, Ahantu ho Gukoresha Porogaramu
Ituma umunyu ukomeza gushonga: Bitewe n'igiciro cyayo gito kandi ikaba ifite ubushobozi bwo gukingira amashanyarazi, yakoreshwaga cyane mu nganda nko mu nsinga n'imiyoboro, ariko buhoro buhoro yagabanutse.
Iterambere rya zinc ya kalisiyumu: rikwiriye imirima idafite ibidukikije nko gupfunyika ibiryo, ibikoresho by'ubuvuzi, inzugi n'amadirishya, kandi nta ngaruka zo kwanduzwa n'ibindi iyo ukoresheje umunyu wa lead na organotin stabilizers.
4, Izindi tandukaniro
Ubucucike n'Ikiguzi: Ibikoresho bigabanya ubucucike bwa kalisiyumu bifite ubucucike buke (hafi 40% munsi y'umunyu wa lead), bishobora kongera ingano ya kalisiyumu karubone ikoreshwa mu kugabanya ikiguzi.
Gusiga amavuta: Umunyu wa lead ufite amavuta meza, mu gihe kalisiyumu na zinki bishingikiriza ku mavuta y'inyongera kugira ngo bigenzure inzira yo gushyira pulasitiki mu mwanya wayo.
Ubushobozi bwo kurwanya gutwika zinc: Ibikoresho bikomeza zinc bya kalisiyumu bisaba kongerwamo ibice by'inyongera nka polyols na fosfite kugira ngo hirindwe kwangirika kwa zinc chloride.
muri make
Nubwo ibikoresho bigabanya umunyu wa lead bikora neza cyane, ibidukikije ntibigira ingaruka nziza. Ibikoresho bigabanya umunyu wa kalisiyumu byagabanyije buhoro buhoro icyuho mu mikorere binyuze mu iterambere ry'ikoranabuhanga (nk'ibikomoka ku butaka busanzwe) kandi biba ibindi bisimbura ibidukikije bisanzwe.
