Zopangira mphira zopangira mphira zimakhala ndi mawonekedwe osiyanasiyana amphasa, monga mphete za mphira, mphasa za PTFE, mphasa zowoneka bwino, mphasa za mpweya, mphasa zosasunthika, mphasa za mphira, mphasa za siponji ndi mphasa za mphira wa hemispherical, mphete zosindikizira, mphasa zosalowa madzi, Ma gaskets a mphira, ma gaskets theka, mapepala odana ndi kugwedezeka, etc.
Zinthu zambiri za mphira ndi mphasa za labala zimapangidwa ndi mphira.Zoonadi, mphira umagawidwanso mu mphira wa ethylene propylene, mphira wachilengedwe (wachilengedwe), mphira wa styrene-butadiene ndi mphira wa butyl.Zina zimagwiritsidwanso ntchito m'mafakitale monga mankhwala, zamagetsi, mankhwala ndi zakudya.Ndiye, mtengo wamtengo wa rabara womwe umagwiritsidwa ntchito kwambiri ndi labala?Kodi ubwino wake ndi wotani?
Ubwino wa zinthu za rabara mat:
1. Mapadi a mphira amatha kupangidwa mosiyanasiyana, kuuma kosiyana, kukhazikika bwino komanso mphamvu, ndi zinthu zomwe zimagwiritsidwa ntchito kwambiri.
2. Mpira wa rabara uli ndi kutentha kwapamwamba kwambiri pa 200 ° C kapena -50 ° C, ndipo akadali ndi elasticity.
3. Ntchito ya dielectric ya mphira ya rabara ndi yabwino kwambiri, ngakhale kutentha kumasintha kwambiri, ntchito yake yotsekemera ikadalipo.ndi
4. Mpira wa rabara umagonjetsedwa ndi ozoni ndi kuwala kwa ultraviolet, ndipo sizovuta kusweka pambuyo pogwiritsira ntchito nthawi yaitali.ndi
5. Mpira wa rabara uli ndi ntchito zabwino monga anti-skid, chitetezo cha chilengedwe, kuvala kukana, kugwedezeka, kugwedeza, kukonza, anti-seepage, kutentha kwa kutentha, etc.
Mwachidule, zopangira mphira ndi ma gaskets a rabara zimakhala ndi ntchito zofananira, monga kusindikiza, kunyamula katundu, kupindika ndi kuyamwa modabwitsa!Ndikoyenera kumadera omwe ali ndi kutentha kochepa komanso kuthamanga kwapansi.Gasket ya rabara imakhala ndi elasticity yayikulu.Malingana ndi mtundu wa rabara, zosowa zosiyanasiyana zapangidwe zingathe kukwaniritsidwa.
M'malo mwake, pakukonza zingwe zomata mphira ndi zinthu zawo za mphira, kapena posungira ndikugwiritsa ntchito, chifukwa cha kuphatikizika kwa zinthu zamkati ndi zakunja, thupi, mankhwala ndi makina azitsulo zosindikizira mphira zimachepa pang'onopang'ono, kapena kutaya.
Chisindikizo cha rabara ndi chankhungu, ndipo kusinthaku kumatchedwa kukalamba kwa rubber seal.(Zimadziwika ndi kusweka, kumamatira, kuuma, kufewetsa, ufa, kusinthika ndi mildew.) Chifukwa cha kusintha kwadzidzidzi kwa kutentha kapena zinthu zina zachilengedwe, mtengo wogwiritsira ntchito mphira wosindikiza mphira umakhudzidwa.
Chifukwa: Popeza pali pafupifupi 10% ya mapuloteni ndi mafuta popanga zingwe zosindikizira mphira, tizilombo tating'onoting'ono tamlengalenga titha kugwiritsa ntchito ngati sing'anga, kotero nkhungu imakula.
二.Njira zochotsera nkhungu pazisindikizo za rabara:
1. Ikhoza kuchiritsidwa ndi yankho la benzoic acid (sodium), ndipo zotsatira za anti-mildew zimakhala bwino.
2. Pukutani ndi zosungunulira (84 mankhwala ophera tizilombo, petulo, toluene, etc.).
3. Kuchotsa kutentha kwakukulu kwa kuphika.
