Niki PVC Stabilisateur

PVC stabilisateurni inyongeramusaruro zikoreshwa mugutezimbere ubushyuhe bwumuriro wa polyvinyl chloride (PVC) hamwe na copolymers. Kuri plastiki ya PVC, niba ubushyuhe bwo gutunganya burenze 160 ℃, kubora ubushyuhe bizabaho kandi gaze ya HCl izakorwa. Niba bidahagaritswe, uku kubora k'ubushyuhe bizarushaho kwiyongera, bigira ingaruka ku iterambere no gukoresha plastike ya PVC.

Ubushakashatsi bwerekanye ko niba plastiki ya PVC irimo umunyu muke, isabune yicyuma, fenol, amine aromatic, nindi myanda, kuyitunganya no kuyikoresha ntibizagira ingaruka, ariko, kubora kwayo birashobora kugabanuka kurwego runaka. Ubu bushakashatsi buteza imbere gushiraho no gukomeza iterambere rya PVC stabilisateur.

Ibisanzwe bya PVC birimo stabilisateur ya organotine, stabilisateur yumunyu wicyuma, hamwe na stabilisateur yumunyu ngugu. Stabilisateur ya Organotine ikoreshwa cyane mugukora ibicuruzwa bya PVC kubera gukorera mu mucyo, guhangana nikirere cyiza, no guhuza. Imyunyu ngugu yumunyu isanzwe ikoresha calcium, zinc, cyangwa umunyu wa barium, ishobora gutanga ubushyuhe bwiza bwumuriro. Imyunyungugu yumunyu ngugu nka tribasic gurş sulfate, dibasic gurş fosifite, nibindi bifite ubushyuhe bwigihe kirekire kandi bitanga amashanyarazi meza. Mugihe uhisemo PVC stabilisateur ikwiye, ugomba gusuzuma imiterere yimikorere yibicuruzwa bya PVC hamwe nibisabwa bihamye. Stabilisateur zitandukanye zizagira ingaruka kumikorere yibicuruzwa bya PVC kumubiri no mubya shimi, kubwibyo rero birakenewe gutegurwa no kugerageza kugirango habeho stabilisateur. Intangiriro irambuye no kugereranya ibintu bitandukanye bya PVC stabilisateur nibi bikurikira:

Imiterere ya Organotine:Stabilisateur ya Organotine niyo ikora neza cyane kubicuruzwa bya PVC. Ibicuruzwa byabo nibicuruzwa biva muri okiside ya organotine cyangwa chloride ya organotine hamwe na acide cyangwa est est ikwiye.

Stabilisateur ya organotine igabanyijemo sulfure kandi idafite sulfure. Amazi arimo sulferi ihagaze neza, ariko hariho ibibazo muburyohe no kwambukiranya ibintu bisa nibindi bintu birimo sulfure. Stabilisateur itari sulfure ubusanzwe iba ishingiye kuri acide ya kigabo cyangwa igice cya acide ya acide. Bakunda methyl tin stabilisateur ntabwo ikora neza yubushyuhe hamwe nubucyo bwiza.

Stabilisateur ya organotine ikoreshwa cyane mubipfunyika ibiryo nibindi bicuruzwa bya PVC bisobanutse nka hose.

Kuyobora Abayobora:Ubusanzwe ibiyobora byangiza bikubiyemo ibintu bikurikira: dibasic lead stearate, hydrated tribasic lead sulfate, dibasic lead phthalate, na fosifate ya dibasic.

Nka stabilisateur yubushyuhe, ibiyobora ntibishobora kwangiza ibintu byiza byamashanyarazi, kwinjiza amazi make, hamwe n’ikirere cyo hanze cy’ibikoresho bya PVC. Ariko,kuyobora stabilisateurufite ibibi nka:

- Kugira uburozi;

- Kwanduzanya kwanduye, cyane cyane na sulferi;

- Kubyara amashanyarazi ya chloride, azakora imirongo kubicuruzwa byarangiye;

- Umubare uremereye, bivamo uburemere / igipimo cyinshi.

- Kurwanya stabilisateur akenshi bituma ibicuruzwa bya PVC bidahita bihinduka kandi bigahinduka vuba nyuma yubushyuhe bukabije.

Nubwo hari izo ngaruka, kuyobora stabilisateur biracyakoreshwa henshi. Kumashanyarazi, amashanyarazi arayobora. Kwungukira ku ngaruka zayo muri rusange, ibicuruzwa byinshi byoroshye kandi bikomeye bya PVC bigerwaho nkibikoresho byo hanze, kaburimbo ya PVC itagaragara, imiyoboro ikomeye, uruhu rukora, hamwe ninshinge.

Umuyoboro wumunyu wicyuma: Uruvange rw'icyuma ruvanzeni igiteranyo cyibintu bitandukanye, mubisanzwe byakozwe ukurikije porogaramu yihariye ya PVC nabakoresha. Ubu bwoko bwa stabilisateur bwagiye buhinduka kuva hiyongeraho barium succinate na cadmium palm acide yonyine kugeza kuvanga kumubiri wa sabune ya barium, isabune ya kadmium, isabune ya zinc, hamwe na fosifike kama, hamwe na antioxydants, umusemburo, kwagura, plasitike, amabara, imashini ya UV, ibimurika. , imiti igabanya ubukana, amavuta, hamwe nuburyohe bwa artile. Nkigisubizo, hari ibintu byinshi bishobora guhindura ingaruka za stabilisateur ya nyuma.

Stabilisateur yicyuma, nka barium, calcium, na magnesium ntabwo irinda ibara ryambere ryibikoresho bya PVC ariko irashobora gutanga ubushyuhe bwigihe kirekire. Ibikoresho bya PVC byahagaze muri ubu buryo bitangira umuhondo / orange, hanyuma bigahinduka umukara, amaherezo bikirabura nyuma yubushyuhe buhoraho.

Cadmium na zinc stabilisateur byakoreshejwe bwa mbere kuko bisobanutse kandi birashobora kugumana ibara ryumwimerere ryibicuruzwa bya PVC. Ubushyuhe bwigihe kirekire butangwa na cadmium na stabilisateur ya zinc ni bibi cyane kurenza ibyo byatanzwe na barium, bikunda kwangirika gitunguranye rwose nta kimenyetso gito cyangwa kidafite.

Usibye kuba igipimo cyicyuma kigereranya, ingaruka zumunyu wumunyu wicyuma nazo zifitanye isano nuruvange rwumunyu, ibyo bikaba aribyo bintu nyamukuru bigira ingaruka kumitungo ikurikira: amavuta, kugenda, gukorera mu mucyo, ihinduka ryibara ryibara, hamwe nubushyuhe bwa PVC. Hasi hari ibyuma byinshi bivangwa na stabilisateur: 2-Ethylcaproate, phenolate, benzoate, na stearate.

Imyunyu ngugu yumunyu ikoreshwa cyane mubicuruzwa byoroshye bya PVC nibicuruzwa byoroshye bya PVC byoroshye nko gupakira ibiryo, ibikoreshwa mubuvuzi, hamwe nububiko bwa farumasi.
