Ukucaciswa

Singoochwephesha ekwenzeni amashiti aphezulu erabha enziwe I-NR, SBR, CR, NBR, EPDM, Viton, Silicone,njl. amashiti ethu erabha enziwa ngokwendlela yomthengi. La maphepha anikezela uzinzo, ukhuseleko kunye namandla. Sivelisa amashiti erabha ngobukhulu obahlukeneyo kunye neepateni. Amashiti erabha aveliswe kuthi asetyenziswa kwizicelo ezahlukeneyo ezinjengeenjongo zokuphamba, iidampu, amabhanti kunye neebhombu. Senza kwaye sithathe isitokhwe iintlobo ezicacileyo zamashiti erabha:Amaphepha eeNjoloba zeNdalo (NR):Ezi shiti zerabha zibonelela ngokubonakalayo kwipropathi ebonakalayo kunye nokuxhathisa kumaqondo obushushu asetyenziselwa ubushushu benkonzo ukuya kuthi ga kwi-80 ° C. Le mveliso sisisombululo esihle kumashishini ahlukeneyo kodwa ayinakuxhathisa kakubi i-ozone esekwe ipetroli ipetroli, ulwelo kunye nokukhanya kwelanga.Amashiti eRuby Styrene-Butadiene Rubber (I-SBR):Ipolymer esetyenziswayo ekwenzeni irabha eyandisiweyo. Kuyinto enoqoqosho kakhulu kwaye ayinazakhiwo zekhemikhali ezizimeleyo. Irabha ye-SBR inokudityaniswa ukubonelela nge-abrasion entle kakhulu, ukunxiba kunye neempawu ezimdaka. I-SBR ingatshintshwa ngokulula irabha yendalo kwizicelo ezininzi ezinokugcina iindleko ezibalulekileyo. Ukunyaniseka kwakhona kuyafana nerabha yendalo. Irabha ye-SBR yinto ephambili kwi-HVAC nakwishishini lokwakha njengoko iguquguqukayo, ibhetyebhetye kwaye yomelele ngokwaneleyo ukuze iphakame. Irabha ye-SBR lukhetho olufanelekileyo xa uthatha isigqibo sokukhetha impahla enezinto ezikhulu zemitshini kunye nokuguquguquka.Amaphepha eeN Rubber zeNeubhine (CR):La maphepha alungele ii-asidi, iialkali kunye namalangatye avulekileyo. Amashiti aneoprene anikezelwa kuthi abalulekiyo kubushushu obuphakamileyo bama-40 ngokuka-120 ° C. Ezi makhishithi zisetyenziswa ngokudibeneyo kwimibutho eyahlukeneyo njengezicoci, iiyunithi zokulungisa kunye namashishini emichiza.Amaphepha eeN Rubber eNitrile (NBR):La maphepha anokungqinelani kakuhle neemveliso zepetroleum kunye namashishini amaninzi anje ngee-oyile ezichasene ne-oyile kunye neegesi. Amashiti erabha e-nitrile agcinwe ngathi anokusebenza ngokulula kubushushu obukhulu be-110 F. Ezi ziqwengana ziqukethe iipropathi ezifanelekileyo zomzimba njengokuxhathisa kwe-abrasion kunye nokumelana nokuguga okuhle.I-Silicone Rubber Sheets(Q):Ezi shiti ziqulathe ukumelana okuhle kweekhemikhali, ii-asidi kunye neealkali. Ezi zigcina iipropathi ze-electrometric ngalo naliphi na ixesha lobushushu. Ime kwi-200 C ngokulula. La maphepha anokuchasana okuphezulu kwe-ozone, imisebe ye-ultraviolet kunye neoksijini kodwa ezo zilungile kumashishini eoyile.Iishiti zeRubber ze-EPDM(I-EPDM):Iishiti zerabha ze-EPDM ezenziwe kuthi zihambelana ngokubalaseleyo kunye nodidi olukhulu lweekhemikhali kunye naphakathi. La mashiti asetyenziswa kakhulu kwimichiza, kwizichumisi nakwimizi-mveliso kumachiza.Amashiti eRubber amaShiti(FPM / FKM):Amashiti e-viton aveliswe kuthi asetyenziselwa amashishini athile obushushu kunye nokumelana neoyile. Ezi zibonakalisa ukuxhathisa okuhle ngokuguga namalangatye.
