Kugawika kwa Zida Zomwe Zimagwira Ntchito Zophatikizana za Rubber Flexible

Zida zazikulu zamphira yowonjezera yowonjezerandi: silika gel osakaniza, nitrile mphira, neoprene, EPDM mphira, mphira zachilengedwe, mphira fluoro ndi mphira ena.

Thupi katundu yodziwika ndi kukana mafuta, asidi, alkali, abrasion, mkulu ndi otsika kutentha.

1. Labala wachilengedwe

Zolumikizira za mphira zopanga zimakhala ndi kutsika kwambiri, kulimba kwakutali, kukana kwabwino komanso kukana chilala, ndipo zitha kugwiritsidwa ntchito pa kutentha koyambira -60 ℃ mpaka +80 ℃.Sing'anga ikhoza kukhala madzi ndi gasi.

2. mphira wa Butyl

Malo olumikizirana mphira osamva kuvala amagwiritsidwa ntchito pamapaipi afumbi ndi mchenga.Mgwirizano wa rabara wosamva kuvala komanso wosagwirizana ndi dzimbiri ndi gulu la mphira laukadaulo lomwe limapangidwira machitidwe a desulfurization.Ili ndi kukana kwabwino, asidi ndi alkali kukana, kukana kwa dzimbiri, ndipo imatha kulipira bwino kukula kwa axial, kukulitsa kwa radial, kusamuka kwa angular ndi ntchito zina za mapaipi a desulfurization.

3. Chloroprene rabala (CR)

Mgwirizano wa rabara wosamva madzi a m'nyanja, womwe uli ndi mpweya wabwino kwambiri komanso kukana kwa ozoni, chifukwa chake kukana kwake kukalamba kumakhala kwabwino kwambiri.Kutentha kogwira ntchito: pafupifupi -45 ℃ mpaka +100 ℃, ndi madzi a m'nyanja monga sing'anga yayikulu.

4. Nitrile rabara (NBR)

Mafuta osagwirizana ndi mphira.Makhalidwe ake ndi kukana bwino kwa gasi la mafuta.Ntchito kutentha osiyanasiyana: pafupifupi -30 ℃ kuti +100 ℃.Chogulitsa chofananira ndi: cholumikizira mphira chosagwira mafuta, chokhala ndi zimbudzi ngati sing'anga.

5. Ethylene propylene diene monomer (EPDM)

Zolumikizira za mphira za Acid ndi alkali zimagwiritsidwa ntchito kwambiri, zomwe zimadziwika ndi kukana kwa asidi ndi alkali, zomwe zimakhala ndi kutentha pafupifupi -30 ℃ mpaka +150 ℃.Lolingana mankhwala: asidi ndi alkali kusamva mphira olowa, sing'anga ndi zimbudzi.

Fluorine rabara (FPM) yolimbana ndi mphira wolumikizana ndi kutentha kwambiri ndi njira yaulimi yopanga elastomer yopangidwa ndi copolymerization ya fluorine yokhala ndi ma monomers.Makhalidwe ake ndi kukana kutentha kwambiri mpaka 300 ℃.

Kuphatikiza pa omwe atchulidwa pamwambapa, pali mayina odziwika bwino: 310 Heat Expansion Joint,Chigwirizano Chokulitsa Manja

Gulu ndi mawonekedwe a magwiridwe antchito

Pogwiritsa ntchito, pali mitundu itatu yaMtengo wa EPDM(makamaka pamafunika kukana madzi, kukana kwa nthunzi wa madzi, ndi kukana kukalamba), mphira wachilengedwe (makamaka mphira womwe umangofunika kukhazikika), mphira wa butyl (mphira womwe umafunikira kusindikiza bwino), mphira wa nitrile (rabala yomwe imafuna kukana mafuta), ndi silikoni (rabala chakudya kalasi);
Kusindikiza mphira kumagwiritsidwa ntchito kwambiri m'mafakitale monga antistatic, retardant flame, electronics, chemical, pharmaceutical, and food.

Zida zolumikizira mphira zimagawidwa m'mitundu yosiyanasiyana kutengera sing'anga yomwe imagwiritsidwa ntchito, monga mphira wa chloroprene, mphira wa butyl, mphira wa fluoro, mphira wa EPDM ndi mphira wachilengedwe.Malumikizidwe a mphira osinthika amagwiritsidwa ntchito kwambiri polumikizira mapaipi osiyanasiyana, okhala ndi magwiridwe antchito a mayamwidwe odabwitsa, kuchepetsa phokoso, komanso kubweza chipukuta misozi.

Ntchito zolumikizira mphira zimasiyanasiyana malinga ndi zomwe zimagwiritsidwa ntchito.Kusiyanitsa kwa magwiridwe antchito kumaphatikizanso mphira wapadera wa fluororubber ndi silikoni, womwe umatha kukana, kukana kupanikizika, komanso kukana kutentha kwambiri.Imakhala ndi kukana kwa mafuta, kukana kwa asidi ndi alkali, kuzizira ndi kutentha, kukana kukalamba, ndi zina zotero. Ponena za makonda, mphira akhoza kupangidwa kukhala mitundu yosiyanasiyana ya mphira yowonjezera yowonjezera.
