Jakisoni Wopangira Mpira Wopangira Zampira

Compression Molding

Popondereza mphira, mphira wa rabara amalowetsedwa mu nkhungu, ndipo kukakamiza kumagwiritsidwa ntchito kukakamiza zinthuzo kuti zikhale mawonekedwe omwe akufuna. Kutentha kumagwiritsidwa ntchito kuchiritsa mphira. Njirayi imagwiritsidwa ntchito kwambiri popanga zinthu monga ma gaskets, zisindikizo, ndi zida zamagalimoto.

Jekeseni Kumangira

Kumangirira jakisoni kumaphatikizapo kubayidwa mphira wosungunuka mu nkhungu mopanikizika kwambiri. Njirayi ndiyabwino popanga zida zovuta komanso zolondola, kuphatikiza zida zamagalimoto ndi zinthu zogula. Kumangirira ndi kuyikapo ndi mitundu yosiyanasiyana ya njirayi, kuphatikizapo kuphatikiza zitsulo zomalizidwa mu nkhungu musanabaya mphira.

Transfer Kuumba

Kuphatikizira mbali za kuponderezana ndi jekeseni, kuumba kumagwiritsa ntchito kuchuluka kwa mphira mu chipinda chotenthedwa. Plunger imakakamiza zinthuzo kuti zilowe mu nkhungu, zomwe zimapangitsa kuti zikhale zoyenera kupanga zolumikizira magetsi, ma grommets, ndi tizigawo tating'ono tolondola.

Extrusion

Extrusion imagwiritsidwa ntchito popanga mphira wopitilira muyeso wokhala ndi mawonekedwe apambali, monga mapaipi, machubu, ndi mbiri. Labala amakakamizidwa kupyolera mu kufa kuti akwaniritse kasinthidwe komwe akufuna.

Kuchiritsa (Vulcanization)

Kuchiritsa, kapena vulcanization, kumaphatikizapo kulumikiza maunyolo a rabara polima kuti awonjezere mphamvu, kukhazikika, ndi kukana kutentha. Izi zimatheka pogwiritsa ntchito kutentha ndi kukakamizidwa kwa mphira wowumbidwa, ndi njira zodziwika bwino monga nthunzi, mpweya wotentha, ndi machiritso a microwave.

Rubber to Metal Bonding

Njira yapadera, yolumikizana ndi mphira kupita kuchitsulo imapanga zinthu zomwe zimagwirizanitsa kusinthasintha kwa mphira ndi mphamvu yachitsulo. Chigawo cha mphira chimapangidwira kapena kuumbidwa, chimayikidwa pamwamba pazitsulo ndi zomatira, kenako chimatenthedwa ndi kutentha ndi kukakamizidwa kuti vulcanization iwonongeke kapena kuchiritsa. Njirayi imamangiriza mphira ku chitsulo, ndikupanga kulumikizana kolimba komanso kolimba ndikofunikira pamapulogalamu omwe amafunikira kugwetsa kugwedezeka komanso chithandizo chamapangidwe.

Kuphatikiza

Kuphatikizira kumaphatikizapo kusakaniza zinthu za rabara zosaphika ndi zowonjezera zosiyanasiyana kuti apange gulu la rabala lomwe lili ndi zinthu zinazake. Zowonjezera zingaphatikizepo machiritso, ma accelerator, antioxidants, fillers, plasticizers, ndi colorants. Kusanganikirana kumeneku kumachitika mu mphero ziwiri kapena chosakaniza chamkati kuonetsetsa kugawa yunifolomu kwa zowonjezera.

Kugaya

Kutsatira kuphatikizika, pawiri mphira amakumana mphero kapena kusakaniza njira kupitirira homogenize ndi kuumba zakuthupi. Sitepe iyi imachotsa thovu la mpweya ndikutsimikizira kufanana mumagulu.

Pambuyo pokonza

Pambuyo pochiritsa, mankhwala a rabara amatha kupitilira njira zina, kuphatikiza kudula, kuwotcha (kuchotsa zinthu zochulukirapo), komanso kuchiritsa pamwamba (monga zokutira kapena kupukuta) kuti zikwaniritse zofunikira.

Natural Rubber (NR):

Kuchokera ku madzi a latex a mtengo wa rabara (Hevea brasiliensis), mphira wachilengedwe amadziwika chifukwa cha kusungunuka kwake komanso kupirira. Zomwe zimagwiritsidwa ntchito kwambiri ngati matayala, nsapato, ndi zinthu za ogula, zimakhala ndi kukana kutentha ndi mankhwala.

Mpira Wopanga:

Amapangidwa mwachisawawa pogwiritsa ntchito njira zamakina, ma rubber opanga amapereka zinthu zambiri. Mitundu ina yodziwika bwino ndi:

Mpira wa Styrene-Butadiene (SBR)

Amagwiritsidwa ntchito kwambiri pokana ma abrasion komanso kulimba, nthawi zambiri amapezeka mumatayala agalimoto ndi malamba onyamula.

Mpira wa Polybutadiene (BR):

Ndiwofunika kupirira kwambiri komanso kusinthasintha kwa kutentha, komwe kumagwiritsidwa ntchito kwambiri popanga matayala komanso ngati chosinthira pamapulasitiki.

Nitrile Rubber (NBR):

Imawonetsa kukana kwapadera kwamafuta, mafuta, ndi mankhwala, ndikupangitsa kuti ikhale yoyenera kusindikiza, ma gaskets, ndi ma O-rings pamagalimoto ndi mafakitale.

Butyl Rubber (IIR):

Amadziwika kuti sangalowe m'magasi, abwino kumachubu amkati a matayala, zomangira zamkati zamatangi osungiramo mankhwala, ndi zoyimitsa mankhwala.

Neoprene (CR):

Amapereka kukana kwanyengo, ozoni, ndi mafuta, kusankha kotchuka kwa ma wetsuits, ma hoses, ndi ma gaskets amagalimoto.

Ethylene Propylene Diene Monomer (EPDM):

Ndiwofunika kukana kutentha, nyengo, ndi ma radiation a UV, omwe nthawi zambiri amagwiritsidwa ntchito popangira denga, zisindikizo zamagalimoto, komanso kutchinjiriza kwamagetsi panja.

Mpira wa Silicone (VMQ):

Amadziwika bwino kwambiri polimbana ndi kutentha komanso kutentha kwamagetsi, zomwe zimagwiritsidwa ntchito kwambiri pazida zamankhwala, zophikira, zopangira magalimoto, komanso ngati chosindikizira.

Fluoroelastomers (FKM):

Imalimbana kwambiri ndi mankhwala, kutentha kwambiri, ndi mafuta, omwe amagwiritsidwa ntchito kwambiri pamakina omwe amafunikira kukana kwapadera kwamankhwala, monga zisindikizo ndi ma gaskets m'mafakitale amankhwala ndi zakuthambo.

Chloroprene Rubber (CR):

Imadziwikanso kuti Neoprene, imapereka kukana bwino kwa nyengo ndi ozoni. Amagwiritsidwa ntchito nthawi zambiri pamapulogalamu omwe amafunikira kuti azikhala ndi thanzi labwino, monga zovala zonyowa komanso zomangira mafakitale.

Polyurethane (PU):

Kuphatikiza mphira ndi pulasitiki, mphira wa polyurethane amayamikiridwa chifukwa cha kukana kwake kwa abrasion komanso mphamvu yonyamula katundu. Amagwiritsidwa ntchito kwambiri m'mawilo, ma bushings, ndi zida zamakina amakampani.
