Kungani I-Silicone Rubber Isetshenziswa Kabanzi?

Isingeniso

Irabha ye-Silicone isiphenduke into eyisisekelo ezimbonini ezahlukahlukene ngenxa yezakhiwo zayo eziyingqayizivele kanye nokuguquguquka. Kusukela kwezezimoto kuye kwezokwelapha, ukusetshenziswa kwayo kuhlanganisa izinhlobonhlobo zezinkambu, okuyenza ibe yinto ebaluleke kakhulu ekukhiqizeni kwesimanje. Le ndatshana icubungula ngezizathu zokutholwa kwenjoloba ye-silicone, ihlola ukwakheka kwayo kwamakhemikhali, izakhiwo ezingokomzimba, kanye nokusetshenziswa okungokoqobo. Ukwengeza, sizohlola indima yayo kubuchwepheshe obusafufusa kanye negalelo layo ekusimameni. Ukuze uthole ukuqonda okuphelele kwezinhlelo zokusebenza ezihlukahlukene zerabha ye-silicone, vakashela Irabha yeSilicone.

Ukubunjwa Kwamakhemikhali Nesakhiwo

Izisekelo Zerabha Ye-Silicone

Irabha ye-Silicone iyi-elastomer yokwenziwa eyakhiwe ngokuyinhloko i-silicon, umoya-mpilo, i-carbon, ne-hydrogen. Isakhiwo sayo somgogodla siqukethe i-silicon nama-athomu omoya-mpilo ashintshanayo, okwenza kube nokuzinza nokuguquguquka okuphawulekayo. Amaqembu e-organic axhunywe kuma-athomu e-silicon angashintshwa ukuze ahambisane nezakhiwo zezinto ezibonakalayo, njengokumelana nokushisa, ukunwebeka, nokungabi namandla kwamakhemikhali.

Cross-Linking kanye Vulcanization

Esinye sezici ezichazayo zerabha ye-silicone ikhono layo lokuxhumanisa i-cross-link, inqubo ethuthukisa amandla ayo okusebenza kanye nokuzinza kwe-thermal. I-Vulcanization, evame ukutholwa kusetshenziswa i-peroxide noma i-platinum catalysts, iguqula i-silicone polymer ibe inethiwekhi enezinhlangothi ezintathu. Le nqubo ibalulekile ezinhlelweni ezidinga ukuqina okuphezulu nokumelana nezimo ezimbi kakhulu.

Izici Eziyinhloko Zerabha Ye-Silicone

Ukuzinza Okushisayo

Irabha ye-Silicone ibonisa ukuzinza okushisayo, igcina izakhiwo zayo kulo lonke izinga lokushisa elibanzi (-60°C kuya ku-300°C). Lokhu kuyenza ilungele ukusetshenziswa ezinjinini zezimoto, izingxenye ze-aerospace, nemishini yezimboni, lapho ukuchayeka emazingeni okushisa aphakeme kuvame.

Ukumelana Kwamakhemikhali

Esinye isici esivelele senjoloba ye-silicone ukumelana kwayo namakhemikhali, afaka ama-acids, izisekelo, nezincibilikisi. Lesi sakhiwo siqinisekisa ukuphila kwayo isikhathi eside nokwethenjwa ezindaweni zamakhemikhali ezinokhahlo, njengamalabhorethri nezindawo zokucubungula amakhemikhali.

Ukuvumelana nezimo kanye ne-Elasticity

Ukuguquguquka kwenjoloba ye-silicone nokunwebeka kuhlala kungashintshile ngokuhamba kwesikhathi, ngisho nangaphansi kwengcindezi ehlala isikhathi eside noma ukuchayeka emisebeni ye-UV. Lokhu kuyenza ibe into ekhethwayo yama-seal, ama-gaskets, namadivayisi wezokwelapha adinga ukusebenza okungaguquki.

Izicelo ze-Silicone Rubber

Imboni Yezimoto

Emkhakheni wezimoto, irabha ye-silicone isetshenziselwa ama-gaskets enjini, ama-hoses, nezimpawu ngenxa yokumelana kwayo nokushisa namakhemikhali. Ikhono layo lokumelana namazinga okushisa aphezulu nokumelana nokuwohloka kwamafutha liqinisekisa ukwethembeka kwezingxenye zenjini ezibalulekile.

Ukunakekelwa Kwezempilo Nezempilo

Irabha ye-silicone yezinga lezokwelapha iyahambelana nezinto eziphilayo, ayinabo ubuthi, futhi imelana nezinqubo zokuvala inzalo, okuyenza ilungele izimila, ama-catheter, namashubhu ezokwelapha. Imvelo yayo engenzi lutho inciphisa ubungozi bokusabela okubi, iqinisekise ukuphepha kwesiguli.

Izicelo zikagesi nezogesi

Izakhiwo ezinhle kakhulu zokuvikela injoloba ye-silicone kanye nokumelana ne-arcing kagesi kuyenza ibe yisisekelo embonini yezogesi. Ivamise ukusetshenziswa ekufakeni amakhebula, izixhumi, nezingubo zokuvikela zezingxenye ezibucayi.

Amathrendi Asafufusa Nezinto Ezintsha

Ukusimama kanye Nezinye izindlela ezivumelana ne-Eco

Njengoba izimboni ziqhubekela phambili ekusimameni, ucwaningo lugxile ekuthuthukiseni ezinye izindlela zenjoloba ye-silicone evumelana nemvelo. Lezi zindlela ezintsha zihlose ukunciphisa umthelela wemvelo wokukhiqiza nokulahlwa ngenkathi kugcinwa izici eziphezulu zezinto ezibonakalayo.

Amasu Okukhiqiza Athuthukile

Ukufika kokuphrinta kwe-3D nezindlela ezithuthukisiwe zokubumba kunwebise amathuba okusetshenziswa kwerabha ye-silicone. Lobu buchwepheshe buvumela ukudalwa kwamajiyometri ayinkimbinkimbi nezixazululo ezenziwe ngezifiso, ezibhekelela izidingo ezithile zemboni.

Isiphetho

Inhlanganisela eyingqayizivele yezakhiwo zenjoloba ye-silicone, okuhlanganisa ukuzinza kwe-thermal, ukumelana namakhemikhali, kanye nokuguquguquka, kuqinise isikhundla sayo njengento eguquguqukayo kuzo zonke izimboni ezihlukahlukene. Ukusetshenziswa kwayo emikhakheni yezimoto, yezokwelapha, neye-electronics kugqamisa ukubaluleka kwayo kubuchwepheshe besimanje. Njengoba ucwaningo luqhubeka nokuphusha imingcele yamakhono ayo, irabha ye-silicone isilungele ukudlala indima ebaluleke nakakhulu emisha yesikhathi esizayo. Ukuze uhlole kabanzi mayelana nezinhlelo zokusebenza ezihlukene, vakashela Irabha yeSilicone.
