Qhov Sib Tw Ntawm Cov Roj Hmab Thiab Silicone Yog Dab Tsi?

Roj Hmab thiab Silicone

Ob leeg roj hmab thiab silicone yog elastomers. Lawv yog cov ntaub ntawv polymeric uas nthuav tawm tus cwj pwm viscoelastic, uas feem ntau hu ua elasticity. Silicone tuaj yeem sib txawv los ntawm kev sib tw ua ke los ntawm cov qauv siv atomic. Tsis tas li, silicones muaj ntau dua tshwj xeeb tshaj li cov khoom siv rubbers. Rubbers yog ib txwm tshwm sim, lossis lawv tuaj yeem ua ke. Raws li qhov no, silicone yuav txawv ntawm roj hmab.

• Silicone yog ib qho ntawm cov elastomers, los yog ib qho ntawm lub rubbers.

• Lub caj dab ntawm cov silicone muaj silicon thiab cov pa oxygen, thaum pob txha ntawm feem ntau ntawm lwm cov rubbers muaj carbon-carbon bonds.

• Cov pob txha muaj kab mob ntau dua cov cua kub, tshuaj lom neeg, cov kab mob fungus, UV thiab Ozone tawm tsam cov roj hmab.

• Cov pob zeb zoo nkauj dua li txhua kab npuas thaiv rau cua sov thaiv kom sov vim nws cov cua kub tsis haum.

• Cov roj hmab lim dej muaj cov khoom tshwj xeeb, uas cov khoom siv organic tsis muaj. Organic rubbers tau plhaw tensile thiab tsim kua muag thaum sov siab thaum cov khoom no zoo heev nyob rau hauv silicone rubbers ntawm tib lub kub.

Roj Hmab

Feem ntau, tag nrho cov elastomers raug suav hais tias yog rubbers uas qhov ntev yuav hloov pauv ntau ntawm stressing, thiab tuaj yeem xa rov qab mus rau qhov tseem fwv tom qab tshem qhov kev ntxhov siab. Cov ntaub ntawv no qhia tau hais tias lub khob kub hloov vim lawv txoj kev ua qauv zoo nkauj. Muaj ntau hom rubbers los yog elastomers xws li roj hmab hluav taws xob, hluavtaws hluavtaws hluavtaws, styrene butadiene roj hmab, nitrile roj hmab, polychloprene, thiab silicone. Tab sis ntuj roj hmab yog lub roj hmab uas tuaj rau peb lub siab thaum peb xav tias cov rubbers. Cov roj hmab yog tau los ntawm cov yas ntawm Heveabrasiliensis. Cis-1, 4-polyisoprene yog cov qauv ntawm cov roj hmab hluav taws xob. Feem ntau ntawm cov rubbers muaj cov tshuab chiv polymer ntawm carbon. Txawm li cas los xij, silicone rubbers muaj silicon nyob rau hauv polymer chains es tsis txhob carbon.

Silicone

Silicone yog cov roj hmab hluavtaws. Nws yog tsim los ntawm kev hloov kho silicon. Silicone muaj lub caj dab ntawm silicon atoms nrog alternating oxygen atoms. Raws li silicone muaj zog ua hluav taws xob silicon-oxygen bonds, nws yog ntau dua kom sov dua lwm rubbers los yog elastomers. Tsis zoo li hauv lwm elastomers, cov pob txha inorganic ntawm silicone ua rau nws tsis kam mus fungus thiab tshuaj dua. Tsis tas li ntawd, cov roj hmab yog ib qho uas tiv thaiv tau cov kab mob ozone thiab UV vim hais tias cov nyiaj muaj silicon oxygen tsis tshua raug cov kabmob no dua cov pa carbon ntawm cov pob txha ntawm cov pob txha ntawm lwm cov elastomers. Silicone muaj lub zog tensile zog thiab txo lub tawm dua lub zog tshaj cov organic rubbers. Txawm li cas los ntawm kev kub muaj peev xwm, nws qhia tau hais tias zoo nkauj thiab tsim khoom. Qhov no yog vim hais tias cov variation ntawm cov khoom nyob rau hauv silicone yog tsawg dua nyob rau hauv high kub. Silicone yog cov xim ntau dua lwm cov elastomers. Cov no yog ob peb ntawm cov khoom siv ntawm silicone. Txawm li cas los xij, txoj sia nyob ntawm silicone rubbers yog luv dua cov organic rubbers. Nws yog ib qho ntawm qhov tsis zoo ntawm cov roj hmab. Tsis tas li ntawd, nws cov viscosity yog siab; Yog li ntawd, nws ua rau cov teeb meem raug tsim vim kev pluag tsis txaus zog.

Roj Hmab yog siv rau ntau daim ntawv sau npe xws li cookware, electronics, automotive daim ntawv thiab lwm yam, vim hais tias ntawm lawv cov cwj pwm elastic. Raws li lawv yog cov ntaub ntawv tsis muaj dej, lawv siv cov sealants, cov hnab looj tes thiab lwm yam. Rubbers los yog elastomers yog cov khoom zoo heev rau cov kev siv tshuaj insulating.

Ntawm tag nrho cov npuas, cov tshuaj yeeb nkab yog zoo dua rau cov cua sov thaiv kom sov vim nws cov cua kub tsis haum. Silicone roj hmab muaj cov khoom tshwj xeeb, uas cov organic co npab tsis muaj. (Tsab ntawv tshooj no muab los ntawm qhov sib txawv hauv qhov Website)
