Zombini iirabha kunye ne-silicone zii-elastomers. Zizinto ze-polymeric ezibonisa indlela yokuziphatha ye-viscoelastic, ebizwa ngokuba yi-elasticity. I-silicone iyakwazi ukwahlulahlula kwiirubber ngesakhiwo seatom. Ukongeza, i-silicones ineempawu ezizodwa ngakumbi kuneerubber eziqhelekileyo. Iirubber zenzeka ngokwendalo, okanye zinokudityaniswa. Ngokusekwe koku, i-silicone inokwahlulwa kwirabha.

Irabha

Ngokubanzi, zonke i-elastomers zithathwa njengeerabha apho ubukhulu bunokutshintshwa ikakhulu ngoxinzelelo, kwaye zinokubuyiselwa kwimilinganiselo yoqobo emva kokususa uxinzelelo. Ezi zinto zibonisa ubushushu bengilazi ngenxa yendlela eyakhiwe ngayo. Zininzi iintlobo zerabha okanye i-elastomers ezinje ngerabha yendalo, i-synthetic poly isoprene, i-styrene butadiene irabha, irabha ye-nitrile, i-polychloprene kunye ne-silicone. Kodwa irabha yendalo yirabha ethi ithi qatha engqondweni yethu xa sijonga iirubber. Irabha yendalo ifunyenwe kwi-latex ye-Heveabrasiliensis. I-Cis-1, i-4-polyisoprene sisakhiwo seerabha yendalo. Uninzi lweerubber luqulathe amakhonkco e-polymer ekhabhoni. Nangona kunjalo, iirubber ze-silicone ziqulathe i-silicon kumatyathanga epolymer endaweni yekhabhoni.

Abicah

Abicah yirabha yokwenziwa. Yenziwe ngokuguqula i-silicon. I-silicone iqukethe umqolo wee-atom ze-silicon ezinokutshintsha kwee-athomu zeoksijini. Njengoko i-silicone inamandla aphezulu e-silicon-oxygen bond, iyakwazi ukumelana nobushushu kunezinye iirubber okanye ielastomers. Ngokungafaniyo nezinye i-elastomers, umqolo ongaphiliyo we-silicone wenza ukumelana kwayo nokungunda kunye neekhemikhali ziphezulu. Ukongeza, irabha yesilicone iyamelana nohlaselo lwe-ozone kunye ne-UV kuba ibhondi yeoksijini yesilicon ayinakuchukunyiswa kolu hlaselo kune-carbon-carbon bond yomqolo kwezinye i-elastomers. Abicah unamandla asezantsi eqine kunye namandla eenyembezi asezantsi kuneerubber zezinto eziphilayo. Nangona kunjalo kumaqondo aphezulu obushushu, ibonisa ukuqina kunye neepropathi ezikrazukileyo. Kungenxa yokuba umahluko weepropathi kwi-silicone incinci kumaqondo obushushu aphezulu. Abicah ihlala yomelele kunezinye elastomers. Ezi zimbalwa zeepropathi eziluncedo ze-silicone. Nokuba kunjalo, ubomi bokudinwa be-silicone rubbers bufutshane kuneerubber ze-organic. Le yenye yezinto ezingeloncedo irabha abicah. Ukongeza, i-viscosity yayo iphezulu; Ke ngoko, ibangela iingxaki zokuvelisa ngenxa yeepropathi zokuhamba kakubi.
Irabha isetyenziselwa usetyenziso oluninzi njenge-cookware, i-elektroniki, usetyenziso lweemoto njl.njl. Nanjengoko zizinto ezingangeni manzi, zisetyenziselwa ukutywina, iiglavu, njl.
Ukusuka kuzo zonke iirubber, i-silicone ilunge ngakumbi kwi-thermal insulation ngenxa yokuxhathisa kwayo ubushushu. Irabha abicah inika iipropati ezikhethekileyo, nto leyo irubber eziphilayo.
