Mpira wa Styrene-Butadiene
Mau oyamba:
Rabara ya styrene-butadiene (SBR), yomwe imadziwikanso kuti polybutadiene rabara, ndi mphira wopangira. Amapangidwa ndi polymerization ya monomers awiri, butadiene ndi styrene. SBR ili ndi kukana kwamphamvu kwambiri, kukana kukalamba komanso kukhazikika, ndipo imagwiritsidwa ntchito kwambiri munthawi zosiyanasiyana.
Kuchuluka kwa ntchito:
Kupanga matayala: SBR ndi imodzi mwama raba omwe amagwiritsidwa ntchito kwambiri popanga matayala. Itha kugwiritsidwa ntchito pamatayala opondaponda, m'mbali ndi thupi kuti apereke kukopa kwabwino komanso kukana kuvala.
Zopangira mphira : SBR imagwiritsidwa ntchito popanga zinthu zosiyanasiyana za mphira, monga zisindikizo, ma hoses, mapaipi, matepi a rabara, etc.
Chokhachokha: Chifukwa SBR ili ndi kukana kovala bwino komanso kukana kutsetsereka, imagwiritsidwa ntchito nthawi zambiri popanga nsapato zamasewera, nsapato zogwirira ntchito ndi ma soles ena.
Zomatira zamafakitale: SBR imagwiritsidwa ntchito ngati gawo la zomatira zamafakitale kumangiriza zida zosiyanasiyana monga zitsulo, mapulasitiki ndi matabwa.
Zida zamasewera :SBR imagwiritsidwanso ntchito kupanga zida zamasewera monga basketball ndi mpira, komanso malo othamangira mayendedwe ndi zida zolimbitsa thupi.
Mwambo jekeseni Anaumba Zopangidwa
Njira Zopangira Zampira Zampira
Kupanga zinthu za labala kumaphatikizapo njira zingapo zovuta kuzisintha zomwe zimasintha mphira kukhala chinthu chomaliza. Njirazi zimasiyana malinga ndi mtundu wa rabara womwe umagwiritsidwa ntchito komanso chinthu chomwe chimapangidwa. Zotsatirazi ndi ntchito zopangira mphira zomwe timapereka kuti zithandizire zosowa zanu:
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.

JekeseniKuumba
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.
