Amazi ya Barium Zinc PVC Stabilisateurni inyongeramusaruro zihariye zikoreshwa mugutunganya polyvinyl chloride (PVC) kugirango zongere ubushyuhe bwumucyo n’umucyo, birinda kwangirika mugihe cyo gukora no kongera igihe cyibikoresho. Hano harambuye birambuye kubigize, gusaba, gutekereza kubitekerezo, hamwe nisoko ryamasoko:
Ibigize hamwe na Mechanism
Izi stabilisateur zigizwe numunyu wa barium (urugero, alkylphenol barium cyangwa 2-etylhexanoate barium) hamwe nu munyu wa zinc (urugero, 2-etylhexanoate zinc), uhujwe nibice bigize synogitike nka fosifite (urugero, tris (nonylphenyl) fosifite) kugirango ushire hamwe na solide (urugero: amavuta yubutare). Bariyumu itanga ubushyuhe bwigihe gito, mugihe zinc itanga igihe kirekire. Ifishi y'amazi ituma kuvanga kimwe muburyo bwa PVC. Ibyavuzwe vuba aha birimo na polyether silicone fosifate ester kugirango irusheho gusiga no gukorera mu mucyo, kugabanya kwinjiza amazi mugihe cyo gukonja.
Ibyiza by'ingenzi
Kutagira uburozi: Nta byuma biremereye nka kadmium, byubahiriza ibiryo-bihuza nibipimo byubuvuzi (urugero, amanota yemewe na FDA muburyo bumwe).
Gutunganya neza: Amazi meza atuma byoroshye gukwirakwizwa mubintu byoroshye bya PVC (urugero, firime, insinga), bigabanya igihe cyo gutunganya no gukoresha ingufu.
Ikiguzi-Cyiza: Kurushanwa hamwe na stabilisateur ya tin organic mugihe wirinda impungenge zuburozi.
Ingaruka zo Guhuza: Iyo bihujwe na calcium-zinc stabilisateur, bakemura ibibazo by "ururimi" mugusohora PVC itajenjetse mukuringaniza amavuta nubushyuhe bwumuriro.
Porogaramu
Ibicuruzwa byoroshye bya PVC: Ikoreshwa cyane muri firime zoroshye, insinga, uruhu rwubukorikori, nibikoresho byubuvuzi kubera kutagira uburozi no kugumana neza.
PVC Rigid: Hamwe nacalcium-zinc stabilisateur, batezimbere gutunganya muma firime no mwirondoro, kugabanya "ururimi" (kunyerera kubintu mugihe cyo gukuramo).
Porogaramu yihariye.
Ibitekerezo bigenga ibidukikije
SHAKA kubahiriza: Ibimera bya Barium bigengwa na REACH, hamwe nibibuza gushonga barium (urugero, 0001000 ppm mubicuruzwa byabaguzi). Amazi menshi ya barium zinc stabilisateur yujuje izo mbibi kubera ubushobozi buke.
Ibindi: Kalisiyumu-zinc stabilisateur igenda yiyongera kubera amabwiriza akomeye y’ibidukikije, cyane cyane mu Burayi. Nyamara, barium zinc stabilisateur ikomeza gukundwa mubushyuhe bwinshi (urugero, ibice byimodoka) aho calcium-zinc yonyine ishobora kuba idahagije.
Imikorere namakuru ya tekiniki
Ubushyuhe bwumuriro: Ibizamini byubushyuhe bihamye byerekana ituze ryagutse (urugero, iminota 61.2 kuri 180 ° C kugirango uhindurwe hamwe na hydrotalcite co-stabilisateur). Gutunganya imbaraga (urugero, gukuramo twin-screw) byunguka mumitungo yabo yo gusiga, kugabanya kwangirika kwimyenda.
Gukorera mu mucyo.
Kwimuka kwimuka.
Inama zo gutunganya
Guhuza: Irinde gukoresha cyane amavuta yo kwisiga ya stearic, kuko ashobora kubyitwaramo umunyu wa zinc, byihuta kwangirika kwa PVC. Hitamogufatanyanka epoxisize amavuta ya soya kugirango yongere ubwuzuzanye.
Umubare: Imikoreshereze isanzwe iri hagati ya 1.5-3 interuro (ibice kuri resin ijana) muri PVC yoroshye na 0.5-22 muburyo bukomeye iyo bihujwe na calcium-zinc stabilisateur.
Inzira yisoko
Abashoferi Gukura: Icyifuzo cya stabilisateur idafite uburozi muri Aziya-Pasifika no muri Amerika ya ruguru biratera imbere udushya muri barium zinc. Kurugero, inganda za PVC mubushinwa ziragenda zifata amazi ya barium zinc stabilisateur kugirango ikore insinga / insinga.
Inzitizi: Kuzamuka kwa stabilisateur ya calcium-zinc (biteganijwe ko CAGR ya 5-7% mubikoresho byinkweto no murwego rwo gupakira) bitera amarushanwa, ariko barium zinc igumana umwanya wacyo mubikorwa byinshi.
Liquid Barium Zinc PVC Stabilisateur itanga impirimbanyi zingirakamaro-zogukoresha neza, ubushyuhe bwumuriro, hamwe no kubahiriza amabwiriza, bigatuma ziba ingenzi mubicuruzwa byoroshye bya PVC byoroshye. Mugihe igitutu cyibidukikije gitera guhinduka kuri calcium-zinc ubundi buryo, imitungo yihariye ituma hakomeza kubaho akamaro kumasoko yihariye. Abashinzwe gutegura bagomba guhuza neza ibisabwa nibikorwa hamwe nubuyobozi bugenga kugirango barusheho kunguka.
