Uma ufana nabantu abaningi, cishe ucabanga ngerabha ye-silicone njenge-insulator. Kodwa bewazi ukuthi irabha ye-silicone empeleni iyaqhuba? Kunjalo, le nto eguquguqukayo ingaqhuba ugesi!
Iyini irabha ye-silicone?
Irabha ye-Silicone iyi-elastomer eyakhiwe nge-silicone-yona ngokwayo i-polymer-ne-oxygen. Ama-Silicone ayizinto ezingasebenzi, ezenziwe ngabantu ezinezinhlobo ezihlukahlukene kanye nokusetshenziswa. Ngokuvamile, zidalwe ngokubopha i-silicon-isici semvelo esigcwele isihlabathi nedwala-namanye ama-athomu, njenge-oxygen, i-carbon, ne-hydrogen.
Yiziphi izakhiwo zenjoloba ye-silicone?
-Irabha ye-Silicone iyi-elastomer eyakhiwe nge-silicone-yona ngokwayo i-polymer-nezokwelapha, izigcwalisi, nezithasiselo.
-Izinjoloba ze-Silicone zisetshenziswa kakhulu embonini, futhi kukhona ukwakheka okuningi.
-Irabha ye-Silicone ngokuvamile ayisebenzi, izinzile, futhi imelana nezimo ezimbi kakhulu namazinga okushisa asuka ku-−55 kuya ku-+300 °C kuyilapho isalondoloza izici zayo eziwusizo.
-Ngenxa yalezi zakhiwo, irabha ye-silicone ingatholakala ezinhlelweni zezimoto njengama-gaskets, seal, namapayipi; izinhlelo zikagesi ezifana nokufakwa kukagesi kanye nezintambo nezintambo ezingashisi ukushisa; izinhlelo zokusebenza zasemkhathini njengama-aviation greases, ama-sealant, izinto zokunamathisela, okokunamathela, ama-spacers/amashimu, ama-encapsulation potting compounds; izicelo zezokwelapha njengama-catheter, amashubhu, izimvu zamanzi/ama-gaskets; kanye nezinhlelo zokusebenza zasekhishini njenge-bakeware (amapani e-muffin), izitsha zokupheka (ama-spatula), njll.
Funda kabanzi:
Yenziwa kanjani irabha ye-silicone?
Ukuze benze irabha ye-silicone, abakhiqizi bengeza i-ejenti yokwelapha kanye ne-accelerator ku-silicone enguketshezi, bese beyixuba futhi bayishise kuze kube yilapho i-silicone carbonizes. Izinhlobo ze-vulcanizing ejenti ezisetshenziswa ku-silicone yerabha vulcanization ikakhulukazi ama-oxides, ama-hydroxides nama-Lewis acids ezinsimbi.
Yiziphi izinzuzo zenjoloba ye-silicone?
Ziningi izinzuzo zenjoloba ye-silicone, okuhlanganisa ukuqina kwayo, ukunethezeka, nokuphepha. Lokhu kuyenza ilungele izinhlelo zokusebenza ezahlukahlukene, kufaka phakathi:
-I-Cookware: Ngenxa yokuthi irabha ye-silicone ikwazi ukumelana namazinga okushisa aphezulu, ivame ukusetshenziswa ku-cookware, njengamacansi okubhaka kanye nesikhunta sekhekhe. Ayinanti futhi, okwenza kube lula ukuyihlanza.
-I-Electrical insulation: Irabha ye-Silicone iyisivikeli esingcono kakhulu sikagesi, okwenza ilungele ukusetshenziswa kwezinhlelo zikagesi ezihlukahlukene.
-Ama-Sealants: Irabha ye-silicone ingasetshenziswa ukuvala izikhala nemifantu ukuze kuvinjwe amanzi noma umoya ukuthi ungangeni.
-Izimoto: Irabha ye-Silicone ivame ukusetshenziswa ezinhlelweni zezimoto ngoba ikwazi ukumelana namazinga okushisa aphezulu nokudlidliza.
Yiziphi ukusetshenziswa kwerabha ye-silicone?
Izicelo zerabha ye-silicone zifaka:
-Automotive: amafasitela nezicabha seal, gaskets, hoses, O-rings
-I-elekthronikhi: ukwahlukanisa, ama-potting compounds, amakhiphedi
-Ukuthuthukiswa kwekhaya: ukuguqulwa kwesimo sezulu, ukukhwabanisa
-Ezokwelapha: amashubhu, ama-seal, ama-gaskets
Iyini imikhawulo yerabha ye-silicone?
Nakuba irabha ye-silicone inezinzuzo eziningi, kunemikhawulo ethile okufanele uyiqaphele, ehlanganisa:
-Ayikwazi ukumelana ne-UV futhi izowohloka ngokuhamba kwesikhathi lapho ichayeke elangeni
-Ayikwazi ukumelana nowoyela nophethiloli
-Akunconyelwe ukusetshenziswa ekusetshenzisweni kokushisa okuphezulu (ngaphezulu kuka-200 ° C noma 392 ° F)
- Ayinamandla njengezinye izinhlobo zenjoloba, ngakho-ke ingase ingafaneleki kuzo zonke izinhlelo zokusebenza
Indlela yokwenza kabusha irabha ye-silicone?
Ukuze kusetshenziswe kabusha irabha ye-silicone, kufanele iqale ihlanzwe futhi ikhishwe noma yikuphi ukungcola. Indlela ejwayeleke kakhulu yokwenza lokhu iwukuhlanza nge-ultrasonic, esebenzisa amaza omsindo we-high-frequency ukususa ukungcola, uwoyela, nokunye ukungcola ezintweni. Uma irabha ye-silicone isihlanziwe, ingahlukaniswa ibe yizicucu ezincane futhi incibilike ukuze iguqulwe ibe yimikhiqizo emisha.
Indlela yokulahla irabha ye-silicone?
Uma unemikhiqizo eyenziwe ngerabha ye-silicone okudingeka uyilahle, kunezindlela ezimbalwa zokwenza. Ungaphinda usebenzise irabha ye-silicone, uyilahle endaweni yokulahla imfucumfucu, noma uyishise.
ukugaywa kabusha: Ungaphinda usebenzise irabha ye-silicone ngokuyichoboza ibe yimpushana bese uyisebenzisa njengenhlanganisela kukhonkolo noma itiyela.
indawo yokulahla udoti: Ungakwazi ukulahla irabha ye-silicone endaweni yokulahla udoti, kodwa izothatha indawo futhi ingase ingaboli amakhulu eminyaka.
ukushiswa: Ungashisa irabha ye-silicone, kodwa izokhipha intuthu enobuthi emkhathini.
