Ibikoresho bitera imbaraga bya PVC bya Barium Zincni inyongeramusaruro zihariye zikoreshwa mu gutunganya polyvinyl chloride (PVC) kugira ngo zongere ubushyuhe n'urumuri, birinde kwangirika mu gihe cyo gukora no kongera igihe cyo kubaho kw'ibikoresho. Dore isesengura rirambuye ry'imiterere yabyo, ikoreshwa, amabwiriza y'ibanze, n'uburyo isoko rihagaze:
Imiterere n'uburyo
Izi stabilizers ubusanzwe zigizwe n'umunyu wa barium (urugero, alkylphenol barium cyangwa 2-ethylhexanoate barium) n'umunyu wa zinc (urugero, 2-ethylhexanoate zinc), hamwe n'ibice bihuza ibintu nka phosphites (urugero, tris (nonylphenyl) phosphite) yo gusya no gushonga (urugero, amavuta ya mineral) yo gukwirakwira. Barium itanga uburinzi bw'igihe gito mu bushyuhe, mu gihe zinc itanga ubusugire bw'igihe kirekire. Ishusho y'amazi ituma habaho kuvanga neza mu buryo bumwe mu buryo bwa PVC. Imvange ziheruka kandi zirimo polyether silicone phosphate esters kugira ngo zinoze ubushyuhe n'ubukonje, bigabanya uburyo amazi yinjira mu gihe cyo gukonjesha.
Ibyiza by'ingenzi
Ntibitera uburozi: Bidafite ibyuma biremereye nka cadmium, byubahiriza amabwiriza agenga ibiribwa n'ibipimo by'ubuvuzi (urugero, amanota yemewe na FDA muri bimwe mu bipimo).
Uburyo bwo gutunganya neza: Imiterere y'amazi ituma byoroshye gukwirakwira mu bikoresho byoroshye bya PVC (urugero, filimi, insinga), bigabanya igihe cyo gutunganya n'ikoreshwa ry'ingufu.
Uburyo bwo Kugabanya Ikiguzi: Irushanwa n'ibikoresho bigabanya uburozi bw'amabati mu gihe hirindwa impungenge z'uburozi.
Ingaruka z'ubufatanye: Iyo bihujwe n'ibintu bitera imbaraga za calcium-zinc, bikemura ibibazo byo "guhindura ururimi" mu gusohora PVC mu buryo buhamye binyuze mu kuringaniza ubushobozi bwo gusya no kudahinduka k'ubushyuhe.
Porogaramu
Ibikoresho bya PVC byoroshye: Ikoreshwa cyane mu bikoresho byoroshye, insinga, uruhu rw'ubukorano, n'ibikoresho by'ubuvuzi bitewe nuko idahumanya kandi ikabika neza.
PVC ikomeye: Bihujwe naibintu bitera imbaraga calcium-zinc, binoza uburyo bwo gutunganya amashusho no kuyatunganya, bigagabanya "gutembera kw'ibintu mu gihe cyo kuyasohora".
Porogaramu zihariye: Imiti ibonerana cyane yo gupakira hamwe n'ibicuruzwa birwanya UV iyo ihujwe n'ibirwanya okisidanti nka 2,6-di-tert-butyl-p-cresol.
Ibipimo ngenderwaho ku mabwiriza n'ibidukikije
Iyubahirizwa rya REACH: Ibinyabutabire bya Barium bigenzurwa hakurikijwe REACH, hamwe n'amabwiriza kuri barium ishongesha (urugero, ≤1000 ppm mu bicuruzwa bikoreshwa). Ibyinshi mu bikoresho bigabanya ubushyuhe bya barium zinc byujuje ibi bipimo bitewe n'uko bidashobora gushonga neza.
Amahitamo: Ibikoresho bigabanya ubushyuhe bwa kalisiyumu-zinc birimo kwiyongera bitewe n'amategeko akaze agenga ibidukikije, cyane cyane mu Burayi. Ariko, ibinini bigabanya ubushyuhe bwa barium zinc biracyakunzwe cyane mu bikorwa bishyushye cyane (urugero, ibice by'imodoka) aho kalisiyumu-zinc yonyine ishobora kuba idahagije.
Imikorere n'amakuru ya tekiniki
Guhagarara neza k'ubushyuhe: Ibizamini by'ubushyuhe budahindagurika bigaragaza ko bihoraho (urugero, iminota 61.2 kuri 180°C ku miti irimo hydrotalcite co-stabilizers). Gutunganya ibintu mu buryo budasanzwe (urugero, extrusion y'imitsi ibiri) bigira akamaro mu miterere yabyo yo gusiga amavuta, bigagabanya kwangirika kw'imitsi.
Gukorera mu mucyo: Imiti igezweho irimo ester za silikoni za polyether igira ubushobozi bwo gutanga urumuri rwinshi (≥90% by'ihererekanya ry'amatara), bigatuma ikoreshwa mu gupfunyika.
Urwango rwo kwimuka: Ibikoresho bihamye byo kubungabunga ibidukikije bigaragaza ko nta kwimuka kw'ibiribwa, bikaba ari ingenzi cyane mu bikorwa nko gupakira ibiryo aho kwimuka kw'inyongera ari ikibazo.
Inama ku bijyanye no gutunganya
Guhuza: Irinde gukoresha amavuta akomoka kuri aside stearic cyane, kuko ashobora kugira ingaruka ku munyu wa zinc, bigatuma PVC yangirika vuba. Hitamo gukoresha amavuta akomoka kuri aside stearic.ibintu bifasha mu kubungabunga umutekanonk'amavuta ya soya yahinduwe kugira ngo yongere ubwuzuzanye.
Igipimo: Ikoreshwa risanzwe riri hagati ya 1.5–3 phr (ibice kuri 100 resin) muri PVC yoroshye na 0.5–2 phr mu buryo bukomeye iyo buvanze n'ibikomeza kalisiyumu-zinc.
Inzira Isoko Rikoresha
Ibitera Iterambere: Gushaka ibikoresho bitagira uburozi muri Aziya-Pasifika na Amerika y'Amajyaruguru biri guteza imbere udushya mu miterere ya zinc ya barium. Urugero, inganda za PVC zo mu Bushinwa zikomeje gukoresha ibikoresho bitagira uburozi bya barium zinc mu gukora insinga/insinga.
Imbogamizi: Izamuka rya calcium-zinc stabilizers (iteganijwe kuba hagati ya 5–7% mu bikoresho by'inkweto n'ibipfunyika) riteza ihiganwa, ariko barium zinc igumana umwanya wayo mu bikorwa byiza cyane.
Ibikoresho bikomeza guhindagurika bya Barium Zinc PVC bitanga uburyo bwo kugabanya ikiguzi, ubushyuhe buhamye, no kubahiriza amategeko, bigatuma biba ngombwa mu bicuruzwa bya PVC byoroshye kandi bitoroshye. Nubwo ibidukikije bituma habaho impinduka mu buryo bwa calcium-zinc, imiterere yabyo yihariye ituma bikomeza kugira akamaro ku masoko yihariye. Abakora ibikoresho bagomba kuringaniza neza ibisabwa mu mikorere n'amabwiriza agenga kugira ngo barusheho kubona inyungu.
