Silicone Roj Hmab Tiab Gasket

Silicone Rubber (MQ, VMQ, PVMQ)

Lub cev, silicones yog raws li silicon, lub caij muab los ntawm quartz. Los tsim cov hoob kawm ntawm hluavtaws elastomers, pendant organic pawg xws li methyl, phenyl thiab cov hlua txuas nrog silicon atoms. Qhov sib ntxiv ntawm sab chains tuaj yeem ua kom muaj kev sib txawv hauv cov khoom. Silicones muaj cua kub zoo heev, nws muaj zog thiab muaj zog tiv thaiv kab mob, zoo dielectric stability, thiab ua rau ntau cov roj, tshuaj, thiab cov kuab tshuaj. Thiab rau tag nrho cov elastomers, silicones muaj qhov zoo tshaj plaws cov khoom yooj ywm ntawm qhov tsawg. Tab sis nws kuj muaj qee yam tsis muaj zog xws li lub zog tsis muaj zog, tsis tsim kua muag thiab hnav tsis taus.

Kho qhov system - Peroxide-kho thiab Platinum kho

Kev sib xyaw silicone tebchaw yog feem ntau peroxide-kho. Platinum-cured compounds tau muab cov khoom yooj yim zog thiab tsis tshua muaj neeg tsis muaj zog txaus. Platinum-cured silicones feem ntau yog siv rau hauv kev kho mob lossis lwm yam tsis tshua muaj neeg tsis muaj zog, tab sis lawv yuav tsum tau tsim nyob rau hauv chav tu huv thiab ntau tus nqi ntawm platinum catalyzer ces lawv tseem kim tshaj cov tshuaj tua kab mob.

Lwm Hom Variations

• Silicones tuaj yeem tsim cov khoom "white list" xwb raws li tau teev nyob rau hauv 21.CFR 177.2600 rau kev siv rau hauv cov ntawv uas tus elastomer yuav raug nyob rau hauv kev muag khoom noj los yog dej haus.
• Silicones tuaj yeem xa rau kev tso cai los ntawm National Sanitation Foundation (NSF) rau kev siv cov dej haus.
• Feem ntau cov twj siv hauv Silicones siv nyob rau hauv kev tsav tsheb xws li khau boots, roj lim valve, gasket nyob rau hauv lub teeb ... .etc.
• Cov khoom siv silicone yuav siv tau rau hauv kev kho mob uas yog yuav tsum ua raws li USP CLASS VI.
