Lisebelisoa tse ka sehloohong tsamotsoako oa ho atolosa rabarake: gel ea silika, rabara ea nitrile, neoprene,EPDM rabara, rabara ea tlhaho, rabara ea fluoro le rabara e meng.
Lintho tsa 'mele li khetholloa ke ho hanyetsa oli, acid, alkali, abrasion, mocheso o phahameng le o tlaase.
1. Rabara ea tlhaho:
Manonyeletso a rabara a maiketsetso a na le elasticity e phahameng, matla a phahameng a bolelele, ho hanyetsa ho apara hantle le ho hanyetsa komello, 'me a ka sebelisoa ka mocheso ho tloha -60 ℃ ho ea +80 ℃. Mocheso e ka ba metsi le khase.
2. Rabara ea Butyl:
manonyeletso a rabara a manganga a sebelisoa liphaepheng tsa lerole le lits'ebetsong tsa lehlabathe. Lenonyeletso la rabara e sa cheng le e thibelang ho bola ke lenonyeletso la rabara le etselitsoeng ka ho khetheha lits'ebetso tsa desulfurization. E na le khanyetso e ntle ea ho roala, ho hanyetsa acid le alkali, ho hanyetsa kutu, 'me e ka khona ho lefella katoloso ea axial, katoloso ea radial, ho falla ha angular le mesebetsi e meng ea liphaephe tsa desulfurization.
3. Rabara ea Chloroprene (CR):
Lenonyeletso la rabara le thibelang metsi a leoatle, le nang le khanyetso e ntle ea oksijene le ozone, ka hona, ho tsofala ha lona ho molemo haholo. Mocheso oa ho sebetsa: hoo e ka bang -45 ℃ ho ea +100 ℃, metsi a leoatle e le oona o ka sehloohong.
4. Rabara ea Nitrile (NBR):
Motsoako oa rabara o hananang le oli. Sebopeho ke ho hanyetsa peterole hantle. Sebaka sa mocheso oa ho sebetsa: hoo e ka bang -30 ℃ ho +100 ℃. Sehlahisoa se ts'oanang ke: motsoako oa rabara o hananang le oli, o nang le likhoerekhoere joalo ka seaplane.
5. Ethylene propylene diene monomer (EPDM):
Manonyeletso a rabara a hanyetsanang le asiti a sebelisoa hangata, a khetholloang ka ho hanyetsa asiti le alkali, ka mocheso o fapaneng o ka bang -30 ℃ ho ea +150 ℃. Sehlahisoa se lumellanang: motsoako oa rabara o hananang le acid le alkali, bohareng ke likhoerekhoere.
Fluorine rabara (FPM) rabara e kopantsoeng ea mocheso o phahameng oa mocheso ke mokhoa oa tlhahiso ea temo oa elastomer o entsoeng ka copolymerization ea fluorine e nang le monomers. Sebopeho sa eona ke ho hanyetsa mocheso o phahameng ho fihlela ho 300 ℃.
Litšobotsi tsa ho khetholla le ts'ebetso
Mabapi le tšebeliso, ho na le mefuta e meraro ea rabara ea EPDM (haholo-holo e hlokehang bakeng sa ho thibela metsi, ho hanyetsa mouoane oa metsi, le ho tsofala ha botsofali), rabara ea tlhaho (haholo-holo e sebelisetsoang rabara e hlokang elasticity feela), rabara ea butyl (rabara e hlokang ts'ebetso e ntle ea ho tiisa). ), rabara ea nitrile (rabara e hlokang ho hanyetsa oli), le silicone (rabara ea boemo ba lijo);
Ho tiisa rabara e sebelisoa haholo liindastering tse kang antistatic, flame retardant, electronics, lik'hemik'hale, meriana le lijo.
Lisebelisoa tsa manonyeletso a rabara li arotsoe ka mefuta e fapaneng ho latela mokhoa o sebelisoang, joalo ka rabara ea chloroprene, rabara ea butyl, fluororubber, rabara ea EPDM le rabara ea tlhaho. Manonyeletso a rabara a feto-fetohang a sebelisoa haholo likhokahanong tse fapaneng tsa liphaephe, tse nang le litšobotsi tsa ts'ebetso ea ho monya ho ts'oenyeha, ho fokotsa lerata, le matšeliso a phalliso.
Mosebetsi oa manonyeletso a rabara o fapana ho latela thepa e sebelisoang. Phapang ea ts'ebetso e boetse e kenyelletsa rabara e khethehileng ea fluororubber le silicone, tse nang le khanyetso ea ho apara, khatello ea khatello le ho hanyetsa mocheso o phahameng. E na le ho hanyetsa oli, ho hanyetsa acid le alkali, ho hanyetsa serame le mocheso, ho hanyetsa botsofali, joalo-joalo Mabapi le ho iketsetsa, rabara e ka etsoa ka mefuta e sa tšoaneng ea motsoako oa ho atolosa rabara.
