Ivelaphi irabha ye-silicone yedosi?

 

Ukuze siqonde izindlela eziningi irabha ye-silicone engasetshenziswa ngazo, kubalulekile ukuqonda imvelaphi yayo. Kule bhulogi, sibheka ukuthi i-silicone ivelaphi ukuze siqonde kabanzi ngezici zayo.

 

Ukuqonda izinhlobo ezahlukene zerabha

Ukuze uqonde ukuthi iyini i-silicone, okokuqala udinga ukwazi izinhlobo ezahlukene zerabha ezitholakalayo. Ngendlela yayo emsulwa, irabha yemvelo ivame ukuqashelwa njenge-latex futhi empeleni ivela ngqo emthini werabha. Lezi zihlahla zaqala ukutholakala eNingizimu Melika futhi ukusetshenziswa kwerabha ngaphakathi kuzo kuqale emasikweni ama-Olmec (i-Olmec ngokwezwi nezwi isho ukuthi “Abantu Berabha”!).

Ngakho-ke noma yini engakhiwanga ngale njoloba yemvelo yenziwe ngumuntu futhi yaziwa ngokuthi yenziwe ngokwenziwa.

Into entsha eyenziwe ngokuxuba izinto ezahlukene ibizwa ngokuthi i-polymer yokwenziwa. Uma i-polymer ibonisa izakhiwo zokunwebeka, ibizwa ngokuthi i-elastomer.

 

Yenziwa ngani i-silicone?

I-Silicone ibizwa ngokuthi i-elastomer yokwenziwa njengoba iyi-polymer ekhombisa ukuqina kwe-viscos - okusho ukuthi ikhombisa kokubili ukujiya kanye nokuqina. Abantu babiza lezi zimpawu zokujiya ngokuthi irabha.

I-silicone ngokwayo yakhiwe nge-carbon, i-hydrogen, i-oxygen kanye ne-silicon. Qaphela ukuthi isithako esiku-silicone sipelwa ngendlela ehlukile. Isithako se-silicon sivela ku-silica etholakala esihlabathini. Inqubo yokwenza i-silicon iyinkimbinkimbi futhi ihilela izigaba eziningi. Le nqubo enzima inegalelo entengo ephezulu yerabha ye-silicone uma iqhathaniswa nerabha yemvelo.

Inqubo yokwenza i-silicone ihilela ukukhipha i-silicon ku-silica bese iyidlulisa kuma-hydrocarbon. Bese ixutshwa namanye amakhemikhali ukuze kwenziwe i-silicone.

 

Yenziwa kanjani irabha ye-silicone?

Irabha ye-silicone iyinhlanganisela yomgogodla we-Si-O ongaphili, onamaqembu asebenzayo e-organic anamathele. Isibopho se-silicon-oxygen sinikeza i-silicone ukumelana nokushisa kwayo okuphezulu kanye nokuguquguquka phezu kwamazinga okushisa ahlukahlukene.

I-silicone polymer ixutshwa nama-filler okuqinisa kanye nezinsiza zokucubungula ukuze kwakheke i-gum eqinile, engaxhunywa ekushiseni okuphezulu kusetshenziswa ama-peroxide noma i-polyaddition curing. Uma isixhunyanisiwe, i-silicone iba yinto eqinile, enamathelayo.

Lapha kwa-Silicone Engineering, zonke izinto zethu ze-silicone zilungiswa kusetshenziswa ukushisa okuhlukanisa imikhiqizo yethu ye-silicone njenge-HTV silicone noma i-High Temperature Vulcanised. Zonke izinhlobo zethu ze-silicone ziyahlanganiswa, zixutshwe futhi zikhiqizwe esikhungweni sethu esingamamitha-skwele angu-55,000 eBlackburn, eLancashire. Lokhu kusho ukuthi sinokulandeleka okugcwele kanye nokuzibophezela kwenqubo yokukhiqiza futhi singaqinisekisa amazinga aphezulu okuphathwa kwekhwalithi kuyo yonke indawo. Njengamanje sicubungula amathani angaphezu kuka-2000 erabha ye-silicone minyaka yonke okusivumela ukuthi sincintisane kakhulu emakethe ye-silicone.

 

Yiziphi izinzuzo zokusebenzisa irabha ye-silicone?

Inqubo yokukhiqiza kanye nokwakheka kwezinto ezenziwe ngerabha ye-silicone kuyinika ukuguquguquka okukhulu, okuyikho okwenza ithandwe kakhulu ngenxa yokusetshenziswa okuningi. Iyakwazi ukumelana nokushintshashintsha okukhulu kwezinga lokushisa kusukela ku--60°C kuya ku-300°C.

Futhi inokumelana okuhle kakhulu kwemvelo okuvela ku-Ozone, i-UV kanye nokucindezeleka okuvamile kwesimo sezulu okwenza kube kuhle kakhulu ukuvala ngaphandle nokuvikela izingxenye zikagesi ezifana nokukhanyisa kanye nezindawo zokuvala. Isiponji se-silicone siyinto elula futhi eguquguqukayo okwenza kube kuhle kakhulu ekunciphiseni ukudlidliza, ukuzinzisa amalunga kanye nokunciphisa umsindo ngaphakathi kwezinhlelo zokuhamba ngobuningi - okwenza kube yinto ethandwayo ukusetshenziswa ezindaweni ezifana nezitimela nezindiza lapho induduzo yamakhasimende isizwa khona ukusetshenziswa kwerabha ye-silicone.

Lokhu kumane nje kuyincazelo emfushane yemvelaphi yerabha ye-silicone. Kodwa-ke, kwa-JWT Rubber siyaqonda ukuthi kubaluleke kangakanani ukuthi uqonde konke ngomkhiqizo owuthengayo. Uma ungathanda ukuthola okwengeziwe ukuze uqonde ukuthi irabha ye-silicone ingasebenza kanjani embonini yakho, xhumana nathi namuhla.
