Zopangira mphira zimatengera mphira waiwisi ndipo amawonjezedwa ndi kuchuluka koyenera kwa mankhwala ophatikizira.…
1.Zachilengedwe kapena mphira wopangidwa popanda kuphatikiza othandizira kapena opanda vulcanization amatchulidwa pamodzi kuti mphira yaiwisi.Labala lachilengedwe lili ndi zinthu zabwino zonse, koma zotulutsa zake sizingakwaniritse zosowa zamakampani, komanso sizingakwaniritse zofunikira zina zapadera, kotero pali ntchito zambiri za mphira wopangira.…
compounding agent Pofuna kukonza ndi kukonza zinthu zosiyanasiyana za labala, chinthu chomwe chawonjezeredwacho chimatchedwa compounding agent.Zinthu zophatikizira makamaka zimaphatikiza minga yowononga, zodzaza, zothamangitsira vulcanization, mapulasitiki, anti-kukalamba ndi zotulutsa thovu.
① Udindo wa vulcanizing wothandizira ndi wofanana ndi wochiritsa mu mapulasitiki a thermosetting.Zimapangitsa maunyolo a mphira a maselo kukhala maunyolo opingasa, olumikizidwa moyenera, ndikukhala mawonekedwe a netiweki, potero amawongolera mawonekedwe ndi mawonekedwe a mphira.Sulfide yomwe imagwiritsidwa ntchito kwambiri ndi sulfure ndi sulfide.…
② The filler ndi kukonza makina amakina mphira, monga mphamvu, kuuma, kukana kuvala ndi kulimba.Zodzaza zomwe zimagwiritsidwa ntchito kwambiri ndi kaboni wakuda ndi nsalu, ulusi, ngakhale mawaya achitsulo kapena zomangira zitsulo ngati zida zomangira.Kuonjezera zodzaza kungathenso kuchepetsa kuchuluka kwa mphira yaiwisi komanso kuchepetsa mtengo wa rabala.…
③ Other compounding wothandizira vulcanization accelerators akhoza imathandizira ndondomeko vulcanization ndi kusintha vulcanization zotsatira;plasticizers ntchito kuonjezera mphira plasticity ndi kukonza akamaumba ntchito;antioxidants (antioxidants) amagwiritsidwa ntchito kuteteza kapena kuchedwetsa ukalamba wa rabara.
2.Mawonekedwe ndi ntchito za zinthu za rabara
Zopangira mphira zimakhala ndi mawonekedwe a elasticity, kulimba mtima kwambiri, mphamvu zambiri komanso kukana kuvala kwambiri.Modulus yake yotanuka ndi yotsika kwambiri, 1-10 MPa yokha, ndipo mapindikidwe ake otanuka ndi aakulu kwambiri, mpaka 100% mpaka 1000%.Ili ndi kusinthasintha kwakukulu komanso mphamvu yosungira mphamvu.Kuphatikiza apo, ili ndi kukana kwabwino kwa kuvala, kutsekereza mawu, kunyowa komanso kutsekereza.Komabe, mphira sulimbana ndi kutentha komanso kuzizira (yomata pakatentha kwambiri, imakhala yolimba ikakumana ndi kuzizira), ndipo imasungunuka mu zosungunulira.…
M'makampani, mphira angagwiritsidwe ntchito kupanga matayala, zisindikizo zosasunthika komanso zosunthika, kugwedera ndikugwetsa magawo oletsa kugwedezeka, malamba otumizira, malamba onyamula ndi mapaipi, mawaya, zingwe, zida zotchinjiriza zamagetsi ndi zida za braking.
