Uma ufuna okokusebenza okuqinile, ukumelana nesimo sezulu okungapendiwa, ungase uthande ukucabangela irabha ye-silicone. Le rabha yokwenziwa inezinzuzo eziningi, okuhlanganisa ukumelana kwayo nokushisa okuphezulu nokuguquguquka kwayo.
Isingeniso
Irabha ye-Silicone ingapendwa ngokusebenzisa ibhulashi lokupenda noma isibhamu se-spray. Ubuso kufanele buhlanzeke futhi bome ngaphambi kokudweba.
Umlando
Irabha ye-Silicone yasungulwa okokuqala elabhorethri ye-General Electric phakathi nawo-1940 nguRussell S. Franklin, umsebenzi wakhe wawuhlobene nokuphayona ucwaningo lwenjoloba ye-polyurethane ngu-Otto Bayer. U-Kohichi Kobayashi, omunye usokhemisi we-GE, wathatha iphrojekthi ngeminyaka yawo-1950 futhi waholela ekuthuthukisweni kwezentengiselwano zamarabha e-silicone ezinhlobonhlobo zezicelo.
Ukubunjwa
Kunezinhlobo eziningi zenjoloba ye-silicone, ngayinye enezakhiwo ezahlukene. Uhlobo oluvame kakhulu yi-polydimethylsiloxane (PDMS), okungamafutha e-silicone anamayunithi aphindaphindayo e-dimethylsiloxane. I-PDMS iwuketshezi olucacile olune-viscosity efana noju. Ingaqiniswa ngokuphulukisa nge-catalyst esekelwe kwi-platinum.
Izici
Enye yezinzuzo eziyinhloko zokusebenzisa irabha ye-silicone ekwenzeni isikhunta izici zayo zokukhulula kalula. Ngokungafani ne-plaster noma ezinye izinto zokubumba, isikhunta se-silicone singacwecwa kalula kude nemodeli ephulukisiwe ngaphandle kokulimaza imodeli. Lesi sici siphinde sivumele ukubunjwa okuningi okuvela ekubunjweni okukodwa - ngemva kokuba isikhunta sihlutshiwe ekubunjweni kokuqala, singasetshenziswa ngokuphindaphindiwe ukuze senze amakhophi aphelele.
Ngaphezu kwezakhiwo zayo ezilula zokukhishwa, irabha ye-silicone nayo inokumelana nokushisa okuphezulu. Lokhu kuyenza ibe yinto ekahle yokwakha isikhunta esizosetshenziswa nezinto ezidinga amazinga okushisa aphezulu ngesikhathi sokuphulukiswa noma ukukhishwa, njengama-epoxy resins.
Izinzuzo
Irabha ye-Silicone ingapendwa ngezizathu eziningi. okokuqala, kuyindlela enhle kakhulu yokufinyelela isiphetho esiqinile, esihlala isikhathi eside. okwesibili, kungasiza ukuvikela i-substrate ekugqwaleni nokunye ukulimala kwemvelo. okwesithathu, ukudweba irabha ye-silicone kungathuthukisa ukubukeka kwayo, kuyenze ibukeke kakhulu.
Okumbi
Kunokungalungi okuningi kokusebenzisa irabha ye-silicone, kufaka phakathi okulandelayo:
-Ayinamandla njengezinye izinhlobo zenjoloba, ngakho-ke ayilungele izinhlelo zokusebenza lapho amazinga aphezulu wamandla edingeka khona.
-Ayikwazi ukumelana nokushisa njengezinye izinhlobo zenjoloba, ngakho-ke ayilungele izinhlelo zokusebenza lapho amazinga okushisa aphezulu ekhathazayo.
-Ayikwazi ukumelana namakhemikhali njengezinye izinhlobo zenjoloba, ngakho-ke ayilungele ukusetshenziswa lapho ukuchayeka kwamakhemikhali kuwukukhathazeka.
Usetshenziswa
Isetshenziswa kaningi njenge- isivikelo sikagesi irabha abicah, ngenxa yamandla ayo aphezulu e-dielectric nokuzinza phezu kwebanga lokushisa elibanzi. Ibuye isetshenziswe njengesithambiso futhi ayizwani nokushisa.
Isiphetho
Ngokusekelwe engxoxweni engenhla, kubonakala sengathi ukudweba irabha ye-silicone kungenzeka, kodwa kunezinto ezibalulekile okufanele uzikhumbule. Okokuqala, uhlobo lwepende oyisebenzisayo kufanele luhambisane nerabha ye-silicone. Okwesibili, kufanele unakekele ukulungisa ubuso berabha ye-silicone yokudweba. Okokugcina, kufanele uhlole upende endaweni encane yerabha ye-silicone ngaphambi Kokuqhubeka nephrojekthi enkulu.
