Ntxiv rau muaj fluorine dawb thiab alkali hlau, nws muaj cov tshuaj tiv thaiv zoo rau tshuaj, cov kuab tshuaj, hydroxides thiab kua qaub. PTFE cov khoom tuaj yeem ntim nrog iav, lub hom phiaj ntawm uas yog txhawm rau txo cov dej txias thiab nkag ntawm PTFE.
2. Cov roj hmab fluorine: zoo rau cov roj, roj, tshuaj chloride daws, cov roj av uas muaj ntxhiab thiab lipid hydrocarbons thiab cov kua qaub zoo heev, tab sis nws tsis tuaj yeem hloov cov amines, lipids, ketones thiab chav. Pom zoo ua haujlwm kub-40 ℃ ~ 232 ℃.
3. Graphite: cov khoom siv no yog cov khoom siv graphite txhua qhov uas tsis muaj cov khoom ntim tawm los yog cov teeb meem inorganic, thiab tuaj yeem muab faib ua cov khoom siv graphite uas ua rau hlau lossis tsis ua rau cov hlau. Cov khoom siv no tuaj yeem hloov mus ua cov yeeb nkab hlaws pob zeb nrog lub taub ntau tshaj 600MM. Cov tshuaj tiv thaiv zoo rau ntau cov kua qaub, cov hauv paus, ntsev thiab cov organic sib tov thiab cov tshav kub hloov ua kom haum, txawm tias qhov kev ntsuas kub siab. Nws tsis tuaj yeem yaj, tab sis yuav sublimate thaum nws tshaj 3316 ° C. Hauv qab qhov kub siab, cov khoom yuav tsum siv nrog kev ceev faj hauv cov xov xwm oxidizing zoo. Ntxiv nrog rau nws qhov kev siv hauv cov gaskets, cov khoom siv no tseem tuaj yeem siv los ua cov kav hlau tsis muaj qhov txhab rau hauv cov qhov txhab thiab cov txhab txhab kiav txhab.
4. Ntuj roj hmab NR: Nws muaj kev txhim kho zoo corrosion rau qaug zog acids thiab alkalis, ntsev thiab chloride kev daws teeb meem, thiab muaj kev xeb tsis zoo rau cov roj thiab cov kuab tshuaj. Nws tsis pom zoo rau ozone media. Pom zoo kev khiav hauj lwm kub yog -57 ° C ~ 93 ° C.
5. Neoprene CR: Neoprene yog cov roj hmab hluavtaws, haum rau cov kua qaub, alkali thiab ntsev daws cov dej tsis muaj tshuaj tiv thaiv corrosion. Kev xeb zoo tiv thaiv kev lag luam roj thiab roj. Tab sis nyob rau hauv muaj zog oxidizing acids, muaj ntxhiab hydrocarbons thiab chlorinated hydrocarbons, lawv cov tshuaj tiv thaiv corrosion tsis zoo. Pom zoo ua haujlwm kub -51 ℃ ~ 121 ℃.
6. NBR: NBR yog cov roj hmab hluavtaws, haum rau ntau qhov kub ntawm qhov muaj peev xwm tiv tau zoo rau roj, cov kuab tshuaj, tshuaj tsw qab hydrocarbons, alkaline hydrocarbons, roj av thiab roj kev ua haujlwm. Cov tshuaj tiv thaiv zoo rau hydroxides, ntsev thiab ze rau ntawm cov kua qaub nruab nrab. Tab sis nyob rau hauv muaj zog oxidizing nruab nrab, cov tshuaj chlorinated hydrocarbons, ketones thiab lipids muaj qhov tsis zoo corrosion. Cov kev ua haujlwm kub siab pom zoo yog 51 ℃ ~ 121 ℃.
7. Chlorosulfonylated polyethylene hluavtaws roj hmab: nws muaj cov tshuaj tiv thaiv zoo rau cov kua qaub, alkali thiab ntsev daws, thiab tsis cuam tshuam los ntawm huab cua, teeb, huab cua, thiab kev lag luam roj (xws li diesel thiab roj av). Pom zoo ua haujlwm kub -45 ℃ ~ 135 ℃. Rau cov tshuaj uas muaj ntxhiab hydrocarbons, chlorinated hydrocarbons, chromic acid thiab nitric acid.
8. Tej hub fiber, tej hub fiber ua rau ntawm sawb: Nws yog qhov zoo gasket khoom haum rau qhov kub thiab txias siab thiab lub teeb ua flange. Qhov kub siab ua haujlwm pom zoo yog 1093 ° C. Nws tuaj yeem siv los ua cov hlau tsis muaj hlau hauv qhov txhab gasket Winding daim kab xev.
9. cov roj hmab silicone: muaj qhov zoo corrosion tsis kam mus rau huab cua kub. Silicone rubber tsis cuam tshuam dab tsi los ntawm tshav ntuj thiab ozone. Tab sis nws tsis tuaj yeem hloov cov pa, ketones, uas muaj ntxhiab hydrocarbons thiab lipid hydrocarbons.
10. Ethylene-propylene roj hmab lined nrog fluorine twj tso kua mis: Nws muaj qhov zoo corrosion tsis kam mus rau muaj zog acid, alkali, ntsev thiab chloride kev daws teeb meem. Nws tsis tuaj yeem hloov cov roj, cov kuab tshuaj, aromatics thiab hydrocarbons. Pom zoo kev khiav hauj lwm kub -57 ° C ~ 176.
