Kapangidwe kakemidwe, magwiridwe antchito ndi ntchito zazikulu zamagulu a rabara wamba

1. Labala lachilengedwe (NR)

Makamaka ndi rabara ya hydrocarbon (polyisoprene), yomwe ili ndi mapuloteni pang'ono, madzi, utomoni wa asidi, shuga ndi mchere wosakhazikika.Kutanuka kwakukulu, kulimba kwamphamvu kwambiri, kukana misozi komanso kutchinjiriza kwamagetsi, kukana kuvala bwino komanso kukana chilala, kusinthika kwabwino, kulumikizana kosavuta ndi zida zina, komanso kuposa ma raba opangidwa ndi zinthu zambiri.Zoyipa zake ndizovuta kukana mpweya ndi ozoni, zosavuta kukalamba komanso kuwonongeka;kukana kosaukamafuta ndi zosungunulira, kukana dzimbiri kutsika kwa zidulo ndi alkalis, ndi kutsika kutentha kukana.Kutentha kwa ntchito: pafupifupi -60℃~ + 80℃.Kupanga matayala, nsapato za mphira, mapaipi, matepi, zotchingira zigawo ndi mawaya ndi zingwe, ndi zina zambiri.mankhwala.Ndiwoyenera makamaka kupanga zotulutsa zotulutsa ma torsional vibration, zotengera kugwedezeka kwa injini, zothandizira makina, zida zoyimitsa mphira-zitsulo, ma diaphragms, ndi zinthu zopangidwa.

2. Rabala ya styrene butadiene (SBR)

Copolymer wa butadiene ndi styrene.Kuchita kwake kuli pafupi ndi mphira wachilengedwe.Ndi mphira wopangidwa ndi cholinga chambiri komanso kutulutsa kwakukulu pakadali pano.Amadziwika ndi kukana kwa abrasion, kukana kukalamba komanso kukana kutentha kwambiri kuposa mphira wachilengedwe, ndipo mawonekedwe ake ndi ofanana kwambiri kuposa mphira wachilengedwe.Zoyipa zake ndi: kutsika pang'ono, kusasunthika kosasunthika komanso kung'ambika;kusagwira bwino ntchito, makamaka kusadzimatira komanso kutsika kwamphamvu kwa rabala wobiriwira.Kupsa mtimamtundu wa chilengedwe: pafupifupi -50℃~＋100℃.Amagwiritsidwa ntchito makamaka m'malo mwa mphira wachilengedwe kupanga matayala, mapepala a rabala, ma hoses, nsapato za rabara ndi zinthu zina zambiri.

3. mphira wa Butadiene (BR)

Ndi mphira wa cis wopangidwa ndi polymerization wa butadiene.Ubwino wake ndi: kukhazikika kwabwino komanso kukana kuvala, kukana kukalamba bwino, kukana kutentha kwambiri, kutsika kwa kutentha kochepa pansi pa katundu wosunthika, komanso kulumikizana kwachitsulo kosavuta.Tkuipa kwake ndi mphamvu zochepa, kukana kugwetsa misozi, kusagwira bwino ntchito komanso kudzimatira.Kutentha kwa ntchito: pafupifupi -60℃~＋100℃.Nthawi zambiri, amagwiritsidwa ntchito limodzi ndi mphira wachilengedwe kapena mphira wa styrene-butadiene, makamaka kupanga matayala.amawerenga, malamba onyamula katundu ndi zinthu zapadera zosagwira kuzizira.

4. Isoprene rabara (IR)

Ndi mtundu wa rabara wa cis wopangidwa ndi polymerization ya isoprene monomer.Kapangidwe kake ndi mawonekedwe amitundu itatu ndi ofanana ndi mphira wachilengedwe, ndipo magwiridwe ake ali pafupi kwambiri ndi mphira wachilengedwe, motero amatchedwa chilengedwe chachilengedwe.mphira.Lili ndi ubwino wambiri wa mphira wachilengedwe.Chifukwa cha kukalamba kwake, mphira wachilengedwe amakhala ndi kutsika pang'ono komanso mphamvu kuposa mphira wachilengedwe, kusagwira bwino ntchito komanso mtengo wokwera.Kutentha kwa ntchito: pafupifupi -50℃~+100℃Itha kulowa m'malo mwa mphira wachilengedwe kupanga matayala, nsapato za rabala, mapaipi, matepi ndi zinthu zina wamba.

5. Neoprene (CR)

Ndi polima wopangidwa ndi emulsion polymerization wa chloroprene monga monoma.Mtundu uwu wa mphira uli ndi maatomu a chlorine mu molekyulu yake, kotero poyerekeza ndi ma rubber ena onse: ali ndi antioxidant yabwino, kukana kwa ozoni, yosayaka, yozimitsa moto, kukana mafuta, kukana zosungunulira, asidi ndi alkali kukana, kukalamba ndi mpweya. kukaniza.Kukhazikika bwino ndi zabwino zina;mphamvu zake zakuthupi ndi zamakina zimakhalanso zabwino kuposa mphira wachilengedwe, kotero zitha kugwiritsidwa ntchito ngati mphira wokhazikika kapena labala wapadera.Zoyipa zazikulu ndi kuzizira kosazizira, mphamvu yokoka yayikulu, kukwera mtengo kwamagetsi, kutsekereza kwamagetsi kosavutikira, kumamatira mosavuta, kupsa, komanso kumamatira nkhungu pokonza.Kuonjezera apo, mphira yaiwisi imakhala ndi stabi wosaukality ndipo si kophweka kusunga.Kutentha kwa ntchito: pafupifupi -45℃~＋100℃.Amagwiritsidwa ntchito makamaka popanga zingwe zazitsulo ndi zophimba zosiyanasiyana zoteteza ndi zophimba zoteteza zomwe zimafuna kukana kwa ozoni komanso kukana kukalamba kwakukulu;mafuta ndi mankhwala kukanamapaipi a ance, matepi ndi linings za mankhwala;mankhwala labala zosagwira lawi kwa migodi mobisa, ndi akamawumba zosiyanasiyana Products, mphete kusindikiza, gaskets, zomatira, etc.
