Intshayelelo: Yintoni irabha ye-silicone?
Irabha yeSilicone yirabha eyenziwe ngesilicon kunye neoksijini. Isetyenziswa kwiintlobo ngeentlobo zezicelo, kubandakanywa izitywina, i-gaskets, i-hoses, izixhobo zonyango, kunye nokufakelwa kombane. Inokumelana nobushushu obugqwesileyo kwaye ingasetyenziswa kwizicelo zobushushu obuphezulu. Irabha ye-Silicone nayo iyamelana neekhemikhali ezininzi kunye nezinyibilikisi. Isetyenziswa kwizicelo ezahlukeneyo ezibandakanya ukufakelwa kwezonyango, izithambiso, kunye nezitywini.
I-Silicone Rubber Material: Imvelaphi kunye nokuBunjwa
I-Silicone Rubber Material yirabha eyenziweyo enezicelo ezininzi. Yayiphuhliswe okokuqala yiNkampani yeDow Chemical kwi-1946. Izinto eziphathekayo zenziwe nge-silicon kunye ne-oxygen kwaye i-inert, ithetha ukuba ayisebenzi kunye nezinye izinto. Oku kuyenza ilungele ukusetyenziswa kumashishini ahlukeneyo, kubandakanya ezonyango, ezemoto, kunye ne-aerospace. I-rubber ye-Silicone isetyenziswe kwiintlobo ezahlukeneyo zezicelo, kubandakanywa: iimeko ze-iphone 4s kunye neefowuni zeefowuni, iideshibhodi zemoto, izixhobo zenkampu, iigundane zekhompyutheni kunye neebhodibhodi, izixhobo zemidlalo, izixhobo zonyango kunye nezixhobo kunye nokunye. I-rubber ye-silicone iphinda isetyenziswe kwizicelo zoshishino kwiimveliso ezininzi ezibandakanya i-hoses, amabhanti okuhambisa kunye neevalvu. Irabha ye-Silicone ineendlela ezahlukeneyo zokusetyenziswa kunye neempawu. Inokubunjwa kwiimilo ezahlukeneyo kwaye inokumelana nokukrala okulungileyo.
Inkqubo yokwenziwa kweRubha yeSilicone
Irabha ye-silicon isoloko isetyenziswa kwizixhobo zonyango, ukupakishwa kokutya, kunye nezinto zokudlala zabantwana kuba ayinayo ityhefu kwaye iyamelana nobushushu. Inkqubo yokuvelisa i-rubber ye-silicone iqala ngokudibanisa i-silanes, ezixutywe ne-silicon kunye ne-hydrogen. Ezi silane ziphinda zixutywe neklorin ukuze zenze iiklorosilane. I-chlorosilanes ke isabela ngeoksijini ukwenza irabha ye-silicone. Irabha ye-Silicone yiplastiki ye-thermoset, oku kuthetha ukuba yenza inethiwekhi edibeneyo yamakhonkco e-polymer (amatyathanga e-polymer ngamatyathanga amade eemolekyuli adityaniswe kunye ngamabhondi ekhemikhali). Irabha ye-Silicone ayinayo ityhefu kwaye iyamelana nobushushu. Imithombo ephambili yetyhefu yioyile ye-silicone esetyenziselwa ukuyenza, kunye nothuli lwe-silicon olusetyenziswe ekudalweni kwayo. I-Siloxanes inetyhefu encinci kuneoli ye-silicone kwaye ayikhuphi amasuntswana amancinci emoyeni.
Iipropati ze-Silicone Rubber
Irabha ye-Silicone iveliswa ngokwenza i-polymerizing izinto zesilicon kunye neoksijini kwinkqubo yekhemikhali ebizwa ngokuba yi-polycondensation. I-Polymerization yenzeka xa isixa esibalulekileyo samandla sisetyenziswa kwii-reactants kwaye senza iimolekyuli ezibotshwe ngamachiza. Ineempawu ezininzi ezenza kube yinto efanelekileyo yokusetyenziswa kwezinto ezahlukeneyo. Irabha yeSilicone iyamelana nobushushu, iyenza ilungele ukusetyenziswa kubushushu obuphezulu obufana ne-cookware, i-bakeware, kunye neendawo zemoto. Kananjalo ayinayo ityhefu kwaye ayinayo i-allergenic, iyenza ikhuseleke ekusebenziseni ukudibana nokutya okanye ulusu. Irabha yeSilicone ikwanwenwe kakhulu, iyenza ilungele ukusetyenziswa kwigaskets, itywina, kunye nezinye izinto zokutywina. Ekugqibeleni, irabha ye-silicone ayinyibiliki kwiintlobo ezininzi ze-solvents eziqhelekileyo, iyenza ixhathise ukuthotywa kwezinto ezivela kwindalo.
Ukusetyenziswa kweRubber yeSilicone
Irabha yeSilicone yipolymer eyenziweyo enezicelo ezininzi. Ihlala isetyenziselwa izixhobo zonyango, kuba ayinayo inetyhefu kwaye inokumelana neempembelelo zeekhemikhali. I-rubber ye-silicone nayo ingasetyenziselwa ukwenza izitywina kunye ne-gaskets, kuba iguquguqukayo kwaye iyamelana neoli kunye namanzi. Ukongeza, irabha ye-silicone ingasetyenziselwa ukugquma iingcingo zombane, kuba iyakwazi ukumelana nobushushu kwaye iyamelana nomlilo.
Ukuqukunjelwa kweRubha yeSilicone
Irabha ye-Silicone ineenzuzo ezininzi ngaphezu kwerabha yendabuko. Iguquguquka ngakumbi, kwaye inokolulwa ngakumbi ngaphandle kokuphuka. Oku kwenza ukuba ilungele ukusetyenziswa kwiimveliso ezifuna ukugoba okanye ukunweba, njengemibhobho kunye netywina. I-Silicone nayo ayinakukwazi ukukrazula okanye ukukrazula, iyenza ibe lukhetho olungcono kwiimveliso eziphantsi kokugqoka kunye nokukrazula. Ukongeza, i-silicone ayinayo inetyhefu kwaye ayixhathisi ukushisa, okwenza kube yinto ekhuselekileyo yokukhetha iimveliso ezidibana nokutya okanye ukushisa. Ukuba unayo nayiphi na imibuzo, nceda shiya umyalezo kuthi.
