Isingeniso: Iyini irabha ye-silicone?
Irabha ye-Silicone iyirabha yokwenziwa eyenziwe nge-silicon nomoya-mpilo. Isetshenziswa ezinhlelweni ezahlukahlukene, kufaka phakathi ama-seal, ama-gaskets, amapayipi, izinsiza zezokwelapha, kanye nokufakwa kukagesi. Inokumelana nokushisa okuhle kakhulu futhi ingasetshenziswa ezinhlelweni zokushisa eziphezulu. Irabha ye-silicone nayo imelana namakhemikhali amaningi nezincibilikisi. Isetshenziswa ekusetshenzisweni okuhlukahlukene okubandakanya izimila zezokwelapha, okokugcoba, nama-sealants.
I-Silicone Rubber Material: Imvelaphi kanye Nokwakheka
I-Silicone Rubber Material iyirabha yokwenziwa enezinhlelo eziningi zokusebenza. Yasungulwa ekuqaleni yi-Dow Chemical Company ngo-1946. Impahla yenziwe nge-silicon nomoya-mpilo futhi ayisebenzi, okusho ukuthi ayisebenzi nezinye izinto. Lokhu kuyenza ilungele ukusetshenziswa ezimbonini ezahlukahlukene, kufaka phakathi ezokwelashwa, ezezimoto, kanye ne-aerospace. Irabha ye-Silicone isetshenziswa ezinhlelweni ezihlukene, okuhlanganisa: amakesi e-iphone 4s namakesi ocingo, amadeshibhodi emoto, izinto zokukhempa, amagundane ekhompyutha namakhibhodi, okokusebenza kwezemidlalo, izinsiza zezokwelapha nezinto zikagesi nokunye. Irabha ye-Silicone nayo isetshenziswa ezimbonini zemikhiqizo eminingi ehlanganisa amapayipi, amabhande okuthutha kanye nama-valve. Irabha ye-Silicone inezinhlobonhlobo zokusetshenziswa nezakhiwo. Ingabunjwa ibe yizimo ezihlukene futhi inokumelana okuhle nokuhuzuka.
Inqubo Yokukhiqiza Yerabha Ye-Silicone
Irabha ye-Silicone ivamise ukusetshenziswa emishinini yezokwelapha, ekufakweni kokudla, kanye namathoyizi ezingane ngoba ayinabo ubuthi futhi imelana nokushisa. Inqubo yokukhiqiza irabha ye-silicone iqala ngokuhlanganiswa kwe-silanes, okuyizinhlanganisela ze-silicon ne-hydrogen. Lawa ma-silane abe esesabela nge-chlorine ukuze akhe ama-chlorosilane. Ama-chlorosilane abe esesabelana nomoya-mpilo ukuze akhe irabha ye-silicone. Irabha ye-Silicone iyipulasitiki ye-thermoset, okusho ukuthi yakha inethiwekhi exhunywe ngokuphambana yamaketanga e-polymer (amaketanga e-polymer amaketanga amade ama-molecule axhunywe ndawonye ngamabhondi amakhemikhali). Irabha ye-Silicone ayinabo ubuthi futhi imelana nokushisa. Imithombo eyinhloko yobuthi ngamafutha e-silicone asetshenziselwa ukuyenza, kanye nothuli lwe-silicon olusetshenziswa ekudalweni kwayo. Ama-Siloxanes anobuthi obuncane kunamafutha abicah futhi awakhiphi izinhlayiya ezincane emoyeni.
Izakhiwo ze-Silicone Rubber
Irabha ye-Silicone ikhiqizwa ngokwenza i-polymerizing izakhi ze-silicon nomoya-mpilo enqubweni yamakhemikhali ebizwa ngokuthi i-polycondensation. I-Polymerization kwenzeka lapho inani elibalulekile lamandla lisetshenziswa kuma-reactants futhi lidala ama-molecule ahlanganiswe ngamakhemikhali. Inezici eziningi eziyenza ibe yimpahla efanelekile yezinhlelo zokusebenza ezihlukahlukene. Irabha ye-Silicone imelana nokushisa, iyenza ilungele ukusetshenziswa ezinhlelweni zokushisa eziphezulu ezifana ne-cookware, i-bakeware, nezingxenye zezimoto. Futhi ayinabo ubuthi futhi ayiyona i-allergenic, okwenza iphephe ukusetshenziswa lapho uthintana nokudla noma isikhumba. Irabha ye-Silicone nayo iyanwebeka kakhulu, iyenza ilungele ukusetshenziswa kuma-gaskets, seal, nezinye izinhlelo zokusebenza zokuvala. Okokugcina, irabha ye-silicone ayincibiliki ezincibilikisini ezivame kakhulu, okuyenza imelane nokuwohloka okuvela ezintweni zemvelo.
Izicelo ze-Silicone Rubber
Irabha ye-Silicone iyi-polymer yokwenziwa enezinhlelo eziningi zokusebenza. Ivame ukusetshenziswa kumishini yezokwelapha, ngoba ayinabo ubuthi futhi ingamelana nethonya lamakhemikhali. Irabha ye-Silicone nayo ingasetshenziselwa ukwenza izigxivizo nama-gaskets, ngoba iguquguquka futhi imelana kokubili uwoyela namanzi. Ukwengeza, irabha ye-silicone ingasetshenziswa njengesembozo sezintambo zikagesi, ngoba ikwazi ukumelana nokushisa futhi imelana nelangabi.
Isiphetho Se-Silicone Rubber
Irabha ye-Silicone inezinzuzo eziningi kunerabha yendabuko. Ivumelana nezimo, futhi inganwetshwa ngokuqhubekayo ngaphandle kokuphuka. Lokhu kuyenza ifaneleke kangcono ukusetshenziswa emikhiqizweni edinga ukugoba noma ukwelula, njengamapayipi nama-seal. I-silicone nayo mancane amathuba okuthi idabuke noma idabuke, okwenza kube ukukhetha okungcono emikhiqizweni eguge kakhulu. Ngaphezu kwalokho, i-silicone ayinabo ubuthi futhi imelana nokushisa, okwenza kube ukukhetha okuphephile emikhiqizweni ehlangana nokudla noma ukushisa. Ngicela, uma unemibuzo shiya umlayezo kithi.
