Ibyiza n'ibibi byo gukoresha methyltin stabilizer ku miyoboro ya PVC

Imashini igabanya ubushyuhe bw'ibati ry'umwimerere (thiol methyl tin) 181 (ikoreshwa mu buryo bwose)

Bangtai Group ikora tini y’umwimerere, yamenyekanye ku isoko kubera ubwiza bwayo buhamye n’imikorere yayo myiza, kandi igakemura neza ibibazo abakoresha bakunze guhura na byo mu bicuruzwa byabo: 1. Ubwiza budahamye; 2. Gukoresha ibicuruzwa mu buryo budasobanutse neza; 3. Ubwiza bw’ibicuruzwa ntibufite ishingiro kandi umwanda urenze urugero; 4. Ikibazo cy’imvura igwa ku buso no gukoresha inyongeramusaruro nke ku bicuruzwa birakwiriye cyane cyane ku bicuruzwa byo mu rwego rwo hejuru bya PVC bitunganywa bifite ibisabwa mu buryo bwo hejuru, ubwiza buhanitse, n’ubukorikori buhanitse.

Imikoreshereze n'imikorere: 181 ni umuti urinda ubushyuhe wa thiol methyl tin ukora neza, utangiza ibidukikije, udahumanya, kandi ukoreshwa mu buryo bwose. Ukoreshwa cyane mu dupira twa PVC, mu dupira twa PVC (harimo udupira two gushyushya, udupira two gucapa), mu dupira twa PVC (harimo udupira dukomeye, udupira duto, udupira tw'amabara) no mu yindi miti, ndetse no mu miyoboro itandukanye ibonerana nk'imiyoboro y'icyuma ya PVC n'imiyoboro yongerewe imbaraga z'imitsi y'inka.

Iki gicuruzwa gifite ibara ribonerana, impumuro yoroheje, imihindagurikire mike, ubwiza burambye kandi buhamye, ndetse n'ubudahinduka mu ntangiriro no mu nyuma. Nyuma yo gukoreshwa, iki gicuruzwa gifite imiterere myinshi nko ubwiza bugaragara cyane, ubushyuhe buhamye, ingano nto yongerwamo, ingaruka zikomeye, n'ubwiza buhamye.

Thiol methyl tin ni umuti urinda ubushyuhe cyane kuri polyvinyl chloride (PVC)

Dukurikije inzego mpuzamahanga z’ubuyobozi, methyl tin ifite ubushyuhe buhamye cyane, ifite ubushobozi bwo gusiga irangi ry’umwimerere, kandi igaragara neza mu bikoresho bigabanya ubushyuhe mu mashini zikoresha ikoranabuhanga.

Mu ngaruka nk'izo, ingano ya methyl tin ikoreshwa ni ntoya ugereranyije n'iya butyl tin na octyltin.

Methyltin yemejwe na FDA yo muri Amerika (21 CFR 178 Mu 2010, iki gicuruzwa cyahawe icyemezo na BGA yo mu Budage (IIA, 4C) kandi gishobora gukoreshwa nk'ibikoresho byo gupfunyika ibiryo n'imiyoboro y'amazi, kandi gifite umutekano wizewe.

Ibikoresho bya PVC bikoresha methyl tin bitanga ubushyuhe bifite ubuziranenge bwiza n'ibara ryiza.

Ifite kandi imikorere myiza yo gutunganya kandi ikwiriye uburyo butandukanye bwo gutunganya polyvinyl chloride (PVC), nko gukurura, gusohora, gusya inshinge, no gusya.

Ariko, ugereranyije n'ibindi bintu bitera imbaraga, thiol methyl tin ifite ikiguzi kiri hejuru, ariko umubare w'inyongera ni muto cyane.

Uburyo bukoreshwa:

Filimi ya PVC (firimi yo gupfunyikamo ubushyuhe, firimi yo gucapa, firimi yo gupfunyika, firimi izunguruka, nibindi)

Impapuro za PVC (impapuro zikomeye zibonerana, impapuro za Noheli, impapuro zo kwamamaza, impapuro zivanze, nibindi)

Uduce twa PVC (ibikoresho by'ibinyabutabire, ibikoresho by'itumanaho by'ikoranabuhanga, nibindi)

Ibikoresho by'ubwubatsi bya PVC (mu miyoboro itandukanye nk'imiyoboro y'amazi n'ibikoresho byayo, imiyoboro y'imiti, imiyoboro y'imitsi y'inka, imiyoboro y'uruhu rw'inzoka, nibindi)

Ibikoresho byo gupfunyika ibiribwa bya PVC n'ibikoresho byo mu rugo bya buri munsi

Ibikoresho by’ubuvuzi bya PVC (amaseti yo gusukamo infusion, nibindi) n’ibindi bicuruzwa Bontecn Group China yashinzwe mu 2003 na Longyang Chemical. Ibigo byose by’itsinda bikora mu gukora inyongeramusaruro za PVC n’inyongeramusaruro za kabutike na pulasitiki. Ni itsinda ry’abahanga rihuza ubushakashatsi bwa siyansi, iterambere, kugurisha, serivisi n’ishoramari. Isosiyete yacu ikora ahanini ibintu bihoraho bifite igenzura rikomeye ry’ubuziranenge bw’ibicuruzwa. Mu myaka myinshi ishize, twakoranye n’ibigo bizwi ku rwego mpuzamahanga, kandi ibicuruzwa byacu byoherejwe muri Amerika ya Ruguru, Amerika y’Epfo, Aziya ya Pasifika, Umuryango w’Ubumwe bw’u Burayi n’ahandi, birushaho kumenyekana mu bakiriya bacu.
