Kom nkag siab qhov zoo thiab qhov tsis zoo ntawm cov tawv silicone

Ua ntej tshaj plaws, silicone tawv muaj kev nyab xeeb txaus, thiab silica gel muaj cov yam ntxwv ntawm biocompatibility, physiological inertia, anticoagulant thiab non-carcinogenicity rau tib neeg lub cev, yog li silica gel yog siv dav hauv cov tshuaj niaj hnub thiab tuaj yeem ua rau pob qij txha, tawv nqaij. thiab lwm yam. cov khoom siv tawv nqaij ua los ntawm cov khoom siv silicon tuaj yeem tiv thaiv kev nkag mus ntawm cov kab mob, tiv thaiv qhov raug mob, tiv thaiv kev kis kab mob thiab muaj kev sib raug zoo nrog rau qhov raug mob.Tsis muaj tshuaj lom neeg, txhawb kev loj hlob ntawm daim tawv nqaij, siv cov silica gel ua ib qho ntawm cov khoom siv raw khoom silicone tawv, nws txoj kev nyab xeeb tuaj yeem pom dav dav.

Cov huab cua zoo heev ntawm silicone tawv:

Silicone tawv muaj zog tiv thaiv huab cua, uas yog pom nyob rau hauv kev tiv thaiv hydrolysis thiab lub teeb; tsis kam mus rau hydrolysis: los ntawm kev xeem rau ntau tshaj kaum lub lis piam (kub 70 ± 2 degree, av noo 95 ± 5 feem pua), tsis muaj degradation xws li stickiness, ci ntsa iab thiab brittleness ntawm daim tawv nqaij; zoo tsis kam rau lub teeb (uv) thiab xim ceev: kev ua tau zoo heev hauv kev tiv thaiv lub hnub ci rau kaum xyoo, tseem tuav nws ruaj khov thiab xim tsis hloov.Silicone tawv silicone tawv waterproof kev ua tau zoo kuj yog tshwj xeeb tshaj yog zoo heev, tsis muaj teeb meem dej npaum li cas, ib tug so huv si.Vim yog cov yam ntxwv ntawm silicone, silicone tawv tuaj yeem tso dej rau hauv cov hlaws, cov dej molecules tsis tuaj yeem hla, thiab cov dej ntawm qhov chaw yuav tsis nkag mus rau hauv daim ntaub.Muaj ob qhov tsis zoo ntawm cov tawv silicone, cov khoom siv raw siv los tsim cov tawv silicone yog me ntsis kim dua, thiab lub zog ntawm cov ntaub tawv tawv yog me ntsis qis dua li cov tawv tiag.
