EPDM ibhodi amagwebu / sheet die ukusika pad / gasket
1. Ukumelana okuphezulu nokuguga
Ukuxhathisa okugqwesileyo kwe-ozone-i-EPDM yaziwa ngokuba yi "rubber engaqhekeziyo", kwaye inokumelana ne-ozone phakathi kweerubha ezinenjongo ngokubanzi.
B Uzinzo olungcono lwe-thermal.
C Ukuchasana nokuguga okugqwesileyo - kunokusetyenziswa ixesha elide kwi-130 ℃, kwaye inokusetyenziswa ngokuphindaphindiweyo okanye ixesha elifutshane kwi-150 ℃ okanye ubushushu obuphezulu.
D Ukuchasana kwemozulu okugqwesileyo - kubhekiselele ekugugeni kwezinto ezidibeneyo zokukhanya, ubushushu, iqhwa, umoya, imvula, i-ozone kunye neoksijini kwindawo yendalo.
2. Ukuchasana kweekhemikhali okugqwesileyo: Ngenxa yokuzinza kweekhemikhali kunye ne-non-polarity ye-EPDM ngokwayo, ayifuni ukusabela ngamachiza kunye neekhemikhali ezininzi, kwaye ayihambelani okanye ayinakho ukuhambelana okuncinci kunye nezinto ze-polar.Ichasene ne-alcohols, i-acids (i-formic acid, i-acetic acid), iziseko ezinamandla, i-oxidants (ezifana ne-H2O2, i-HCLO, njl.), i-detergents, i-oyile yezilwanyana kunye nemifuno, i-ketones, amafutha athile kunye ne-hydrazine.
3. Ukuchasana kwamanzi okugqwesileyo, ukuxhathisa ukufudumala kunye nokumelana nomphunga wamanzi: amanzi yinto eqinile ye-polar, kunye ne-EPDM irabha luhlobo lwe-macromolecular alkanehydrazine ene "hydrophobicity".Akukho ukusebenzisana kweekhemikhali phakathi kwezi zimbini, ngoko inokumelana nokugqwesa kwamanzi, ukumelana nobushushu obugqithisileyo kunye nokumelana nomphunga wamanzi.
Iimpawu zezinto ze-EPDM
Iimpawu zeMveliso ze-EPDM i-rubber foam sponge: Imveliso ihlukaniswe kwi-cell evaliweyo kunye ne-foam evulekile.Iseli yangaphakathi yezinto ezivaliweyo ze-foam zihlukaniswe kwiseli ngefilimu yodonga, engaxhunywanga omnye komnye.Sisakhiwo seseli esizimeleyo, kwaye eyona nto ingundoqo Ifana neseli encinci okanye incinci kakhulu i-micro-cell;iiseli zangaphakathi zezinto ezivulekileyo ze-foam zidibene kunye, kwaye zikwadibaniswa nesikhumba sangaphandle, esisisakhiwo seseli esingaxhomekekiyo, ngokuyininzi iiseli ezinkulu okanye imingxuma erhabaxa.
Izinto zeseli ezivaliweyo: ukumelana nemozulu okugqwesileyo;ubuninzi obuncinci, amandla aphezulu okukrazula;conductivity ephantsi ye-thermal;ukufunxa kakuhle ukothuka.
Izinto zokuvula: ukumelana nemozulu ebalaseleyo;ukumelana nobushushu obuphezulu, ukumelana nobushushu obuphantsi;ukugcinwa kobushushu, ukugquma kakuhle kobushushu;ukuxhathisa i-oyile ye-polar, ukumelana neekhemikhali;ukunyanzeliswa okuphezulu kokumelana namanzi, ukufunxa isandi esilungileyo.
Izinto zeseli ezivaliweyo: ezisetyenziselwa ukupakishwa kwezixhobo ezichanekileyo, izixhobo zonyango, ucango lwesithuthi kunye nezitywina zefestile, i-injini efunxa isandi kunye nezinto ezifunxa ukothuka;i-air-conditioning, ukutywinwa kwefriji kunye nezixhobo zokukhusela ukushisa.Izinto ezifunxa isandi kwiindonga, ukupakishwa komphunga kunye nokupakishwa kwamanzi kwiimveliso zombane.
Izinto zokuvula: Njengomgangatho ophezulu wokufakelwa kwe-thermal, ukufunxa ukothuka, imathiriyeli yokufunxa isandi, isetyenziswa kwiimoto, i-air conditioner, i-electronics, izakhiwo ezivakalayo, iindlela, iibhulorho kunye nezinye iindawo.
Irabha ye-EPDM ye-EPDM inokumelana nemozulu elungileyo, ukumelana nobushushu, ukumelana nokuguga, ukutywinwa kokumanzisa kunye nezinye iimpawu, kwaye ingasetyenziswa kwindawo yomoya ophakathi, ukugqunywa kombhobho wefriji, iipadi ze-buffer, ukufunxa isandi kunye nokunciphisa ingxolo kunye nezinye iinkalo.
