Irabha ye-silicone ewuketshezi olungeziwe (i-ALSR) iyinto ye-polymeric esebenza kahle kakhulu eye yaqashelwa kabanzi emikhakheni eyahlukene yezimboni. Ngokuyisisekelo, yakhiwe njengenhlanganisela efana ne-paste, ene-polydimethylsiloxane eqediwe yi-vinyl esebenza njenge-polymer eyisisekelo, ehlanganiswe nama-agent akhethekile okuxhumanisa kanye nama-catalyst. Lokhu kwakheka okuyingqayizivele kunikeza i-ALSR izakhiwo ezihlukile njengokuguquguquka okuhle kakhulu, ukuzinza kokushisa, kanye nokumelana namakhemikhali, okwenza kube ukukhetha okuthandwayo kwezinhlelo zokusebenza ezidinga ukunemba nokuthembeka. Ngokungafani nezinye izinhlobo zamarabha e-silicone, inqubo yokwelapha ye-ALSR iqhubeka ngokusabela kokwengeza, okubonakala ngokuncishiswa okuphansi, ukungabikho kokukhishwa komkhiqizo olandelanayo, kanye nekhono lokwelapha kokubili ekushiseni kwegumbi kanye nasezingeni lokushisa eliphakeme, ngaleyo ndlela kuthuthukisa ukuzivumelanisa kwayo nezimo ezahlukene zokukhiqiza.
Ukuhlukaniswa kwerabha ye-silicone yokwelapha okungeziwe kusekelwe kakhulu ezindinganisweni ezimbili ezibalulekile: uhlobo lomkhiqizo kanye nokusebenza/ukusetshenziswa. Ngokombono wohlobo lomkhiqizo, ingahlukaniswa ibe irabha ye-silicone eqinile kanye nerabha ye-silicone ewuketshezi. Phakathi kwazo, irabha ye-silicone ewuketshezi, ikakhulukazi uhlobo lokwelapha okungeziwe, ivelele ngokugeleza kwayo ngaphambi kokulungiswa, okuvumela ukuthi ifakwe kalula ezikhumbeni eziyinkimbinkimbi, okuvumela ukukhiqizwa kwezingxenye eziyinkimbinkimbi nezinembile kakhulu. Ngokuphathelene nokusebenza kanye nokusetshenziswa, i-ALSR ihlukaniswe ngohlobo lwenhloso ejwayelekile kanye nohlobo olumelana nokushisa okuphansi. I-ALSR yenhloso ejwayelekile ihlangabezana nezidingo eziyisisekelo zezicelo eziningi zezimboni, njengokuvala, ukubopha, kanye nokubumba, kuyilapho i-ALSR engamelana nokushisa okuphansi iklanyelwe ngqo ukugcina ukuguquguquka kwayo kanye nezakhiwo zayo zemishini ezindaweni ezinzima zokushisa okuphansi, okwenza ifaneleke ukusetshenziswa ezimbonini zezindiza, zezimoto, kanye neziqandisi lapho ukuzinza kokushisa okuphansi kubalulekile khona.
Izinhlobo eziningana ezivamile zamarabha e-silicone angeziwe asetshenziswa kabanzi ekukhiqizweni kwezimboni, kanti irabha ye-silicone ye-dimethyl silicone kanye nerabha ye-silicone ye-methyl vinyl yiyona emele kakhulu. Irabha ye-silicone ye-Dimethyl, eyaziwa ngokushisa kwayo okuhle kakhulu kukagesi, ukumelana nesimo sezulu, kanye nokungangeni kwamakhemikhali, isetshenziswa kakhulu embonini ye-elekthronikhi kanye nekagesi yokukhiqiza ama-insulator, ama-gasket, kanye nezembozo zokuvikela. Irabha ye-silicone ye-Methyl vinyl, ngakolunye uhlangothi, inezakhiwo ezithuthukisiwe ze-vulcanization kanye namandla omshini ngenxa yokwethulwa kwamaqembu e-vinyl, okwenza ifaneleke kakhulu ezinhlelweni zokusebenza ezidinga amandla aphezulu okudonswa kanye nokumelana nokudabuka, njengezimbozo zezimoto, amadivayisi ezokwelapha, kanye nezingxenye zokudla. Ngokuthuthuka okuqhubekayo kobuchwepheshe bezimboni, ububanzi bokusetshenziswa kwerabha ye-silicone ewuketshezi engeziwe iyanda, futhi inhlanganisela yayo eyingqayizivele yezakhiwo izoqhubeka nokushayela ukusungula izinto ezintsha emikhakheni eyahlukene yobuchwepheshe obuphezulu.
