Ivela phi idosi yerabha yesilicone?

 

Ukuqonda ubuninzi beendlela zokusebenzisa irabha ye-silicone, kubalulekile ukuqonda imvelaphi yayo.Kule bhlog, sijonga apho i-silicone ivela khona ukuze siqonde ngakumbi malunga neempawu zayo.

 

Ukuqonda iintlobo ezahlukeneyo zerabha

Ukuze uqonde ukuba yintoni i-silicone kufuneka uqale wazi iintlobo ezahlukeneyo zeerubha ezikhoyo.Ngeyona ndlela icocekileyo, irabha yendalo ibonwa ngokuqhelekileyo njenge-latex kwaye ivela ngqo kumthi werabha.Le mithi yafunyanwa okokuqala eMzantsi Melika kwaye ukusetyenziswa kwerabha ngaphakathi kuyo kubuyela kwinkcubeko ye-Olmec (i-Olmec ngokoqobo ithetha "Abantu beRubber"!).

Nantoni na engenziwanga kule rabha yendalo ngoko ke yenziwe ngumntu kwaye yaziwa ngokuba yi-synthetic.

Into entsha eyenziwe ngokuxuba imathiriyeli eyohlukeneyo kunye ibizwa ngokuba yipolima yokwenziwa.Ukuba i-polymer ibonisa iimpawu ezinwebekayo, ichongiwe njenge-elastomer.

 

Yintoni eyenziwe nge-silicone?

I-silicone ichongwa njenge-elastomer yokwenziwa njengoko iyipolymer ebonisa i-viscoelasticity - oko kukuthi ibonisa zombini i-viscosity kunye no-elasticity.Ngokwe-Colloquially abantu babiza ezi mpawu ilastiki yirabha.

I-Silicone ngokwayo yenziwe nge-carbon, i-hydrogen, i-oksijini kunye ne-silicon.Qaphela ukuba isithako esiqulethwe ngaphakathi kwe-silicone sipelwa ngokuhlukileyo.Isithako se-silicon sivela kwi-silica ephuma kwisanti.Inkqubo yokwenza i-silicon inzima kwaye ibandakanya izigaba ezininzi.Le nkqubo inzima inegalelo kwixabiso leprimiyamu yerabha ye-silicone xa kuthelekiswa nerabha yendalo.

Inkqubo yokwenza i-silicone ibandakanya ukukhupha i-silicon kwi-silica kwaye idlulise ngee-hydrocarbons.Emva koko ixutywe kunye nezinye iikhemikhali ukwenza abicah.

 

Yenziwa njani irabha ye-silicone?

Irabha ye-Silicone yindibaniselwano ye-inorganic Si-O backbone, kunye namaqela asebenzayo e-organic aqhotyoshelweyo.Ibhondi ye-silicon-oksijini inika i-silicone ukumelana kwayo nobushushu obuphezulu kunye nokuguquguquka ngaphezu kwamaqondo amaninzi.

I-silicone yepolymer ixutywe kunye neefayili eziqinisayo kunye nezixhobo zokucubungula ukwenza i-gum eqinile, enokuthi emva koko idityaniswe kwiqondo lokushisa eliphakamileyo usebenzisa i-peroxides okanye i-polyaddition curing.Nje ukuba idityaniswe i-silicone iba yinto eqinileyo, i-elastomeric.

Apha kubuNjineli beSilicone, zonke izinto zethu ze-silicone zinyangwa kusetyenziswa ubushushu obuchaza iimveliso zethu ze-silicone njenge-silicone ye-HTV okanye i-High Temperature Vulcanised.Onke amabakala ethu e-silicone afakwe, axutywe kwaye enziwa kwi-55,000-sq yethu.iziko eBlackburn, eLancashire.Oku kuthetha ukuba sinokulandelelwa ngokupheleleyo kunye noxanduva lwenkqubo yokuvelisa kwaye sinokuqinisekisa imigangatho ephezulu yolawulo lomgangatho kulo lonke.Okwangoku sisebenza ngaphezulu kwe-2000 yeetoni zerabha ye-silicone ngonyaka ngamnye esivumela ukuba sikhuphisane kakhulu kwindawo yentengiso ye-silicone.

 

Ziziphi iingenelo zokusebenzisa irabha ye-silicone?

Inkqubo yokuvelisa kunye nokwakhiwa kwezinto zerubha ye-silicone inika inani elikhulu lokuguquguquka, nto leyo eyenza ukuba idume ngokusetyenziswa okuninzi.Iyakwazi ukumelana nokuguquguquka okugqithisileyo kweqondo lobushushu ukusuka kwi--60°C ukuya kutsho kuma-300°C.

Ikwanayo nokumelana nokusingqongileyo okugqwesileyo okuvela kwi-Ozone, i-UV kunye noxinzelelo lwemozulu ngokubanzi iyenza ilungele ukutywinwa kwangaphandle kunye nokukhusela izinto zombane ezinjengokukhanya kunye neendawo ezivaliweyo.Isiponji se-Silicone sisixhobo esikhaphukhaphu kunye nezinto eziguquguqukayo zenza ukuba zilungele ukunciphisa ukungcangcazela, ukuzinzisa amalunga kunye nokunciphisa ingxolo ngaphakathi kwezicelo zokuhamba ngobuninzi - okwenza ukuba kudume ukusetyenziswa kwiindawo ezifana nezitimela kunye neenqwelo-moya apho induduzo yabathengi incedwa ngokusetyenziswa kwerabha ye-silicone.

Lo ngumbono nje omfutshane wemvelaphi yerabha ye-silicone.Nangona kunjalo, kwiJWT Rubber siyayiqonda indlela ekubaluleke ngayo ukuba uqonde yonke into malunga nemveliso oyithengayo.Ukuba ungathanda ukufumanisa ngakumbi ukuqonda ukuba irabha ye-silicone inokusebenza njani kwishishini lakho ke qhagamshelana nathi namhlanje.
