Pali mitundu yambiri ya mapepala a mphira, mapepala opangira mphira, mapepala otetezera mphala rabara oyaka moto, ndi zina zotero, zonse zimakhala za mapepala a mphira omwe ali ndi katundu wapadera, monga mapepala a mphira opangira mphira amafunikira kukana kwazing'ono, kuyika mapepala a rabara omwe amafunikira kwambiri电阻率，malawi耐火mphira mapepala ndi可燃性等。Kugwiritsa ntchito mwanzeru mphira kubwezeredwa popanga matabwa apadera pulasitiki awa sanganggowonjezera luso laukadauulo wa zipangizo mphira, komanso mogwira kuchepetsa mtengo wa zipangizo pansi pa maziko kuonetsetsa khalidwe。咱mankhwala。
1.Mbale ya mphira ya导电
Kukana magetsi导电mphira mbale ndi laling'ono kwambiri, ndi ntchito ambiri mphira丁腈kapena mphira neoprene ndi极性lalikulu, ndi kapangidwe mkulu wa乙炔mpweya wakuda，导电ng'anjo wakuda等。Popanga传电mphira pepala ndi腈mphira monga chopangira chachikulu, mphira woponderezedwa wa matayala kapena mphira wopangidwanso ndi腈akhoza kuwonjezeredwa kuti achepetse mtengo wamtengo wapatali wa pepala lopangira labala bwino。Kugwiritsa ntchito bwino ufa wachitsulo kungapangitsenso kusintha kwamagetsi kwa mbale yopangira mphira。Kufunsira kwa pulasitiki kumagwiritsa ntchito mtundu wa磷酸酯bwino。
2.Pulati ya mphira ya绝缘
Labala yopanda polar imakhala ndi电阻yayikulu, magwiridwe antchito abwino amagetsi, monga mphira wa乙丙ndi mphira wa butyl, mphira wachilengedwe amathanso kugwiritsidwa ntchito ngati mphira wamagetsi otsika。Popanga zenizeni, EPDM yobwezeretsedwanso labala ndi mphira wa butyl HYL10Y9Y2Y angagwiritsidwe ntchito ndi mitundu yofananira ya mphira kukonzekera mbale yotsika mtengo yotchingira mphundu, yomwe ingachepetse mtengo ndikuwongolera magwiridwe antchito azinthu za rabara;Kupanga mphira wachilengedwe wa bolodi yamagetsi yotsekereza mphira wocheperako kungakhalenso koyenera kugwiritsa nchito mphira wamatayala wobwezeretsedwanso。
Mukamagwiritsa ntchito mphira wobwezeretsedwa kuti mupange bolodi yotchingira mphira, ndi bwino kusankha njira yolimbikitsira yomwe imapangidwa ndi mpweya wakuda wokhala ndi mawonekedwe otsika ndi dongo，滑石粉，碳酸钙等。Kuti mufewese, sankhani parafini kapena gwiritsani nchito parafini ndi gumaron yolimba, kapena gwiritsani nchito。胺类抗衰老剂akulimbikitsidwa kuti azitha kukalamba, monga kuwonjezera mlingo woyenera wa抗衰老剂H akhoza kupititsa patsogolo kutsekemera kwa magetsi pa bolodi la rabara。
3.阻燃rabara mbale
Labala yokhala ndi卤素，mphete ya苯kapena bondi yolumikizidwa pawiri nthawi zambiri imatha kuyaka bwino, monga mphira wa氯丁橡胶，mphira wa氟，rabala ya silikoni, ndi zina zambiri; rabala wa苯乙烯丁二烯，rabala wa丁二烯ndi mphira wachilengedwe ndi mphira woyaka moto。Kuonjezera zobwezeretsanso malawi monga氯化石蜡，三氧化二锑ndi aluminiyamu氢氧化钠mu rabara yoyaka zimatha kupititsa patsogolo kuwonongeka kwa labala。Zopangira mphira zobwezeretsedwanso mu mphira wobwezerezedwanso wa tayala, mphira wobwezeretsedwa wa EPDM ndi zinthu zina zitha kusakanikirana mumtundu wa rabala woletsa moto, kuchepetsa mtengo wazinthu Zopangira。
4.Valani mbale ya rabala yosamva
kuvala -kukana mphira ndi mkulu kuvala kukana，弹性wabwino, makhalidwe otsika phokoso, zofunika ntchito mphira abrasion kukana, kukana mphamvu, kukana misozi, mphamvu mkulu，弹性wabwino, ambiri ndi mphira zachilengedwe ndi苯丁苯甲酸mphira monga zopangira zazikulu ndi zoyenera。Kugwiritsa ntchito mphira wobwezeretsedwa wa latex, mphira wobwezeretsedwanso matayala, mphira wobwezeretsedwa wa tinronitrile angagwiritsidwe ntchito popanga zinthu potengera kuchepetsa mtengo wazinthu zopangira。
