1, Nitrile rabara
Zigwa za solenoid zimapangidwa kuchokera ku emulsion polymerization wa bunadiene ndi acrylonile, makamaka opangidwa ndi kutentha kochepa emulsion polymerization. Ili ndi mafuta abwino kwambiri, kuvala kwambiri kukana, kutenthetsa kwamphamvu komanso kutsatira kwamphamvu. Zoyipa zake ndi kutentha kwa kutentha kochepa kukana, ozoni osauka a Ozoni, magwiridwe antchito osauka, komanso kuperewera pang'ono.
Kuphatikiza apo, ilinso ndi madzi abwino, mpweya wabwino komanso wotsatsa bwino magwiridwe antchito. Amagwiritsidwa ntchito kwambiri popanga zinthu zosiyanasiyana zosagonjetsedwa ndi mafuta, mafuta osiyanasiyana, ma galoni, zosinthira, zida zopangira, kukopera, mafakitale ndi mafakitale ambiri. Makampani ena.
Nitrile Mbewu (NBR) imakhala ndi madzi abwino kwambiri, chachiwiri chokha ku Polysulfide mu mphira ndi fluorolorubber, ndi kuvala zolimba ndi mpweya. Choyipa cha NBR ndikuti sichingachititse ozone ndi hydrocarbon, lokhala ndi hylegeenatic, atone ndi ester, motero sioyenera kuthirira zinthu.
Kugwiritsa Ntchito Kwambiri: Nbr zimagwiritsidwa ntchito makamaka kupaka mapaipi osagwira Mafuta, matepi, ma diaphragms ambiri ophatikizira, chikho, chotupa cham'madzi, et.
2, epdm mphira
EPDM ndi mtunda wa Ethylene, Propylene ndi Dienegeting Diene. Inali yobisidwa mu 1963. Dziko limadya matani 800,000 pachaka. Makhalidwe akuluakulu a Epdm ndi abwino kukana kukana, ozoni kukana ndi kukana kutukuka. EPDM ndi ya polyolefin ndipo ili ndi magwiridwe antchito abwino. Ethylene Pronsomene Womener (EPDM) ali ndi gawo lotsika kwambiri mu ma ruble onse. Itha kuyamwa kwambiri filler ndi mafuta, ndipo sathandiza kwambiri ntchito yake. Chifukwa chake, mankhwala otsika mtengo amatha kupangidwa.
Kapangidwe kake ndi katundu
Kapangidwe: Ethylene Prodolymer ndi msewu wa ethylene, Propylene ndi Dienezatid diene. Ma neenes ali ndi zida zapadera. Chimodzimodzi mwa zingwe ziwiri zokha zitha kukhala zopambana. Cholumikizira kawiri chimagwiritsidwa ntchito ngati wothandizira. Polymer ina yosasinthika si tcheni chachikulu, koma unyolo mbali. Chiyanjano chachikulu cha EPDM chimadzazidwa kwathunthu. Katunduyu amapanga kutentha kolimba, osagwirizana, osagwirizana, oxygen, makamaka ozoni akunjana. Ethylene Prodolymer, makamaka osagwirizana, kugonjetsedwa ndi yankho la Polar ndi mankhwala, mayamwidwe amadzi otsika magwiridwe antchito.
Mawonekedwe: 1. Katundu wamagetsi; 2. 3. Kuchita Zabwino; 4. Kuchulukitsa kotsika ndi kudzaza kwambiri; 5.. 6. Madzi am'madzi; 7. Anti {{}} nyumba yokalamba; 8.
3, fluororubber (fkm)
Pali mitundu yosiyanasiyana ya fluorine {{}} okhala ndi manyowa molekyu molingana ndi zinthu zosiyanasiyana za fluorine, makamaka kapangidwe kake. Pakadali pano, fluororber yokhala ndi syxafluoria dongosolo ndiye nthawi yoyamba Rustior adatchula m'dzina la "Fluororuberi". Kukana kutentha kwakukulu ndikwabwino kuposa rabara silika. Ili ndi mankhwala abwino a mankhwala, kukana mafuta ambiri ndi ma sol sol osatha (kupatula ma ketone ndi esster), kukana nyengo yabwino ndi ozoni osakanizana; Amagwiritsidwa ntchito kwambiri m'makomweko, b ndi zinthu zina, ndipo zisindikizo mu mankhwala mankhwala, ndi kutentha kwa ntchito kuyambira {4} digiri 260 mpaka 260 digiri. Pakakhala kutentha kochepa, kumatha kugwiritsidwa ntchito kwa - 40, koma mtengo sichabwino. Okwera.
