I-EPDM Foam board/ishidi lokufa lokusika iphedi/gasket
1. Ukumelana okuphezulu nokuguga
Ukumelana Okuhle kakhulu kwe-ozone - i-EPDM yaziwa ngokuthi "irabha engaqhekezi", futhi inokumelana ne-ozone okungcono kakhulu phakathi kwamarabha enhloso ejwayelekile.
B Ukuzinza okungcono kwe-thermal.
C Ukumelana nokuguga okuhle kakhulu - kungasetshenziswa isikhathi eside ku-130 ℃, futhi kungasetshenziswa ngezikhathi ezithile noma okwesikhashana ku-150 ℃ noma izinga lokushisa eliphakeme.
D Ukumelana nesimo sezulu esihle kakhulu - kubhekisela ekugugeni kwezici ezihlanganisiwe zokukhanya, ukushisa, amaqhwa, umoya, imvula, i-ozone nomoya-mpilo endaweni yemvelo.
2. Ukumelana namakhemikhali okuhle kakhulu: Ngenxa yokuzinza kwamakhemikhali kanye nokungeyona i-polarity ye-EPDM ngokwayo, ayiphenduli ngamakhemikhali ngamakhemikhali amaningi, futhi ayihambisani noma inokuhambisana okuncane nezinto ze-polar.Imelana notshwala, ama-acids (i-formic acid, i-acetic acid), izisekelo ezinamandla, ama-oxidants (njenge-H2O2, i-HCLO, njll.), okokuhlanza, amafutha ezilwane nemifino, ama-ketone, amafutha athile, ne-hydrazine.
3. Ukumelana kwamanzi okuhle kakhulu, ukumelana nokushisa ngokweqile kanye nokumelana nomswakama wamanzi: amanzi ayinto eqinile ye-polar, futhi i-EPDM irabha iwuhlobo lwe-macromolecular alkanehydrazine ene "hydrophobicity".Akukho ukusebenzisana kwamakhemikhali phakathi kwalokhu okubili, ngakho inokumelana okuhle kwamanzi, ukumelana nokushisa ngokweqile kanye nokumelana nomhwamuko wamanzi.
Izinto ezibonakalayo ze-EPDM
Izici zomkhiqizo we-EPDM i-rubber foam sponge: Umkhiqizo uhlukaniswe ngamaseli avaliwe kanye ne-open-cell foam.Iseli elingaphakathi lezinto ezivaliwe ze-foam zihlukaniswa neseli ngefilimu yodonga, engaxhunywanga komunye nomunye.Iwuhlaka oluzimele lweseli, futhi oluyinhloko Iyingqamuzana elincane elifana neseli noma elincane ngokwedlulele;amangqamuzana angaphakathi e-open-cell foam material axhumene nomunye nomunye, futhi abuye axhunywe nesikhumba sangaphandle, okuyisakhiwo samaseli esingazimele, ikakhulukazi amangqamuzana amakhulu noma izimbobo eziqinile.
Impahla yeseli evaliwe: ukumelana nesimo sezulu esihle kakhulu;ukuminyana kwenqwaba encane, amandla aphezulu ezinyembezi;conductivity ephansi ezishisayo;ukumuncwa ukushaqeka okuhle.
Izinto zokuvula: ukumelana nesimo sezulu esihle kakhulu;ukumelana nokushisa okuphezulu, ukumelana okuhle kokushisa okuphansi;ukulondolozwa kokushisa, ukufakwa kahle kokushisa;ukumelana nowoyela we-polar, ukumelana namakhemikhali;ukumelana nokucindezelwa kwamanzi okuphakeme, ukumuncwa okuhle komsindo.
Izinto ezisetshenziswa kumaseli avaliwe: ezisetshenziselwa ukupakisha amathuluzi anembayo, okokusebenza kwezokwelapha, isicabha semoto nezivalo zamafasitela, izinto ezimunca umsindo zenjini nezinto ezimunca ukushaqeka;air-conditioning, ukuvalwa kwesiqandisi kanye nezinto zokuvikela ukushisa.Izinto ezimunca umsindo zezindonga, ukupakishwa okungangenwa yiphunga nokungangeni kwamanzi emikhiqizweni kagesi.
Izinto zokuvula: Njengezinga eliphezulu lokufakwa kwe-thermal, ukumuncwa ukushaqeka, izinto zokumunca umsindo, isetshenziswa ezimotweni, ama-air conditioner, izinto zikagesi, izakhiwo ezilalelwayo, imigwaqo, amabhuloho neminye imikhakha.
Irabha ye-EPDM EPDM inokumelana nesimo sezulu esihle, ukumelana nezinga lokushisa, ukumelana nokuguga, ukuvala uphawu lokudambisa kanye nezinye izici, futhi ingasetshenziswa endaweni yokupholisa umoya emaphakathi, ukufakwa kwepayipi leyunithi yesiqandisi, ama-buffer pads, ukumuncwa komsindo nokunciphisa umsindo neminye imikhakha.
