Irabha yemveloilungele amanzi, amanzi olwandle, umoya, igesi ye-inert, i-alkali, isixazululo samanzi kasawoti kanye neminye imidiya, kodwa ayimelani nowoyela wamaminerali kanye nezincibilikisi ezingezona ze-polar, izinga lokushisa lokusetshenziswa kwesikhathi eside alidluli ku-90 ℃, ukusebenza okuphansi kwezinga lokushisa kuhle kakhulu. , ingasetshenziswa ngenhla -60 ℃.

  Irabha ye-Nitrileilungele imikhiqizo ye-petroleum, efana ne-petroleum, uwoyela wokugcoba, uwoyela kaphethiloli, njll., izinga lokushisa lokusetshenziswa kwesikhathi eside liyi-120 ℃, njengamafutha ashisayo angamelana no-150 ℃, izinga lokushisa eliphansi lingu -10 ~ -20 ℃.

  Irabha ye-Neopreneilungele amanzi olwandle, i-asidi ebuthakathaka, i-alkali ebuthakathaka, isixazululo sikasawoti, ukumelana kahle kakhulu ne-oxygen nokuguga kwe-ozone, ukumelana nowoyela kungaphansi kwerabha ye-nitrile futhi kungcono kunenye injoloba evamile, izinga lokushisa lokusetshenziswa isikhathi eside elingaphansi kuka-90 ℃, izinga lokushisa eliphezulu lokusetshenziswa alikwenzi. idlula i-130 ℃, izinga lokushisa eliphansi lingu-30~-50 ℃.

Kunezinhlobo eziningi zeIrabha ye-fluorine, banokuphikiswa okuhle kwe-asidi, ukumelana ne-oxidation nokumelana nowoyela, ukumelana ne-solvent. Ingasetshenziswa cishe kuyo yonke imidiya ye-asidi kanye namanye amafutha nezincibilikisi, izinga lokushisa lokusetshenziswa kwesikhathi eside elingaphansi kuka-200 ℃.

Ishidi lenjoloba njenge-gasket ye-flange, esetshenziselwa kakhulu amapayipi noma imigodi evame ukuhlakazwa, izimbobo zezandla, ingcindezi ingeqi ku-1.568MPa. Ngoba kuzo zonke izinhlobo zama-gaskets, ama-gaskets enjoloba athambile kakhulu, asebenza kahle ngokubopha, futhi angadlala umphumela wokuvala ngaphansi kwamandla amancane okulayisha ngaphambilini. Ngenxa yalokhu, lapho ungaphansi kwengcindezi yangaphakathi, kulula ukucindezelwa ngenxa yobukhulu noma ubulukhuni obuphansi be-gasket.

Ishidi lerabha elisetshenziswa ku-benzene, i-ketone, i-ether nezinye izinyibilikisi eziphilayo, ukubonakala kalula ukuvuvukala, ukuzuza isisindo, into ethambile, enamathelayo, okuholela ekuhlulekeni kokuqina. Ngokuvamile, uma izinga lokuvuvukala lidlula ama-30%, alikwazi ukusetshenziswa.

Endabeni yokucindezela okuphansi (ikakhulukazi ngaphansi kwe-0.6MPa) kanye ne-vacuum, ukusetshenziswa kwamaphedi enjoloba kufaneleka kakhulu. Izinto zenjoloba zinokuminyana okuhle nokungena kancane. Isibonelo, irabha ye-fluorine ifaneleka kakhulu ukuvala ama-gaskets ezitsheni ze-vacuum, futhi i-vacuum degree ifinyelela ku-1.3 × 10-7Pa. Uma iphedi yenjoloba isetshenziswa ebangeni le-vacuum degree engu-10-1~10-7Pa, idinga ukubhakwa futhi iphampelwe.
