Ivela phi irabha ye-silicone yeDose?

 

Ukuze siqonde iindlela ezininzi ezinokusetyenziswa ngazo irabha ye-silicone, kubalulekile ukuqonda imvelaphi yayo. Kule blog, sijonga apho i-silicone ivela khona ukuze siqonde ngakumbi ngeempawu zayo.

 

Ukuqonda iintlobo ezahlukeneyo zerabha

Ukuze uqonde ukuba yintoni i-silicone, kufuneka uqale wazi iintlobo ezahlukeneyo zerabha ezikhoyo. Kwimo yayo ecocekileyo, irabha yendalo idla ngokuqatshelwa njenge-latex kwaye ivela ngqo kumthi werabha. Le mithi yafunyanwa okokuqala eMzantsi Melika kwaye ukusetyenziswa kwerabha ngaphakathi kuyo kususela kwinkcubeko yama-Olmec (i-Olmec ithetha "Abantu beRabha"!).

Nantoni na engadalwanga ngale rabha yendalo yenziwe ngumntu kwaye yaziwa ngokuba yeyokwenziwa.

Into entsha eyenziwe ngokuxuba izinto ezahlukeneyo ibizwa ngokuba yi-synthetic polymer. Ukuba i-polymer ibonisa iimpawu ze-elastic, ichongwa njenge-elastomer.

 

Yenziwa ngantoni i-silicone?

I-Silicone ichongwa njenge-elastomer yokwenziwa kuba yi-polymer ebonisa i-viscoelasticity - oko kukuthi ibonisa zombini i-viscosity kunye ne-elasticity. Ngokwesiqhelo abantu babiza ezi mpawu ze-elastic njengerabha.

I-silicone ngokwayo yenziwe ngekhabhoni, i-hydrogen, i-oksijini kunye ne-silicon. Qaphela ukuba isithako esikwi-silicone sibhalwe ngendlela eyahlukileyo. Isithako se-silicon sivela kwi-silica ephuma kwisanti. Inkqubo yokwenza i-silicon iyinkimbinkimbi kwaye ibandakanya amanqanaba amaninzi. Le nkqubo inzima inegalelo kwixabiso eliphezulu lerabha ye-silicone xa ithelekiswa nerabha yendalo.

Inkqubo yokwenza i-silicone ibandakanya ukukhupha i-silicon kwi-silica ize iyidlulise kwii-hydrocarbons. Emva koko ixutywa nezinye iikhemikhali ukwenza i-silicone.

 

Yenziwa njani irabha yesilicone?

Irabha yesilicone yindibaniselwano yomqolo we-inorganic Si-O, kunye namaqela asebenzayo e-organic aqhotyoshelweyo. I-silicon-oxygen bond inika isilicone ukumelana nobushushu bayo obuphezulu kunye nokuguquguquka kumanqanaba obushushu ahlukeneyo.

I-silicone polymer ixutywe nezihluzi zokuqinisa kunye nezixhobo zokucubungula ukwenza i-gum eqinileyo, enokuthi emva koko idityaniswe kubushushu obuphezulu kusetyenziswa ii-peroxides okanye i-polyaddition curing. Nje ukuba idityaniswe, i-silicone iba yinto eqinileyo, ethambileyo.

Apha kwiSilicone Engineering, zonke izinto zethu zesilicone zinyangwa kusetyenziswa ubushushu obuchaza iimveliso zethu zesilicone njenge-HTV silicone okanye iHigh Temperature Vulcanised. Zonke iiklasi zethu zesilicone ziyaxutywa, zixutywe kwaye zenziwe kwiziko lethu elingama-55,000-sq. ft. eBlackburn, eLancashire. Oku kuthetha ukuba sinokulandeleka ngokupheleleyo kunye noxanduva lwenkqubo yemveliso kwaye sinokuqinisekisa imigangatho ephezulu yolawulo lomgangatho kuyo yonke indawo. Okwangoku sicubungula ngaphezulu kweetoni ezingama-2000 zerabha yesilicone minyaka le nto isenza sikwazi ukukhuphisana kakhulu kwimarike yesilicone.

 

Zithini iingenelo zokusebenzisa irabha ye-silicone?

Inkqubo yokuvelisa kunye nokwakheka kwezinto ezenziwe ngerabha ye-silicone kuyinika ukuguquguquka okukhulu, nto leyo eyenza ukuba ithandwe kakhulu kwiindlela ezininzi. Iyakwazi ukumelana nokuguquguquka okukhulu kobushushu ukusuka kwi--60°C ukuya kwi-300°C ephezulu.

Ikwanayo nokumelana okuhle nokusingqongileyo okuvela kwi-Ozone, i-UV kunye noxinzelelo lwemozulu ngokubanzi okwenza ukuba ilungele ukuvalwa kwangaphandle kunye nokukhuselwa kwizinto zombane ezifana nokukhanyisa kunye neendawo ezivalekileyo. Isiponji se-silicone sisixhobo esikhaphukhaphu nesinokuguquguquka esenza ukuba ilungele ukunciphisa ukungcangcazela, ukuzinzisa amalungu kunye nokunciphisa ingxolo kwiindawo zokuhamba ngobuninzi - okwenza ukuba ithandwe ukusetyenziswa kwiindawo ezifana noololiwe kunye neenqwelo-moya apho intuthuzelo yabathengi incedwa kukusetyenziswa kwerabha ye-silicone.

Olu lushwankathelo nje olufutshane lwemvelaphi yerabha ye-silicone. Nangona kunjalo, kwi-JWT Rubber siyaqonda ukuba kubaluleke kangakanani ukuba uqonde yonke into malunga nemveliso oyithengayo. Ukuba ungathanda ukufumana ulwazi oluthe kratya ukuze uqonde indlela irabha ye-silicone esebenza ngayo kushishino lwakho, nxibelelana nathi namhlanje.
