Unikani ubwino ndi kuipa kwa ma polyurethane casters achitsulo cha mafakitale

Chotsukira cha polyurethane chapakati pa iron ndi mtundu wa chotsukira chokhala ndi zinthu za polyurethane, cholumikizidwa ku chotsukira chapakati pa iron, chotsukira chapakati pa iron kapena chotsukira chapakati pa iron, chomwe ndi chodekha, cholemera pang'onopang'ono komanso chotsika mtengo, ndipo chimagwira ntchito m'malo ambiri ogwirira ntchito.
Kawirikawiri, kukula kwa ma casters a mafakitale kumakhala pakati pa mainchesi 100-200 (100-200mm), ndipo mawilo a polyurethane ndi abwino kwambiri. Mawilo a polyurethane ali ndi kukana kwabwino kwa kukwawa, magwiridwe antchito osiyanasiyana osinthika, njira zosiyanasiyana zokonzera, kugwiritsidwa ntchito kwakukulu, komanso kukana bwino mafuta, ozone, ukalamba, kuwala kwa dzuwa, kutentha kochepa, ndi zina zotero, kulowetsa bwino mawu, mphamvu yolimba yomatira, kuyanjana bwino kwa zinthu zachilengedwe komanso kugwirizana kwa magazi.

Ma polyurethane casters amadziwika kwambiri ndi zinthu zotsatirazi:
1. Kuchuluka kwa magwiridwe antchito osinthika. Kupyolera mu kusankha zinthu zopangira ndikusintha njira, zimatha kusinthasintha mkati mwa kusintha kwina kwa zizindikiro zingapo zakuthupi ndi zamakanika, kuti zikwaniritse zofunikira zapadera za wogwiritsa ntchito pa magwiridwe antchito azinthu. Mwachitsanzo, ma elastomer a polyurethane amatha kupangidwa kukhala ma roller osindikizira ofewa a rabara ndi ma roller olimba achitsulo kuti akwaniritse zosowa za ogwiritsa ntchito osiyanasiyana.
2. Kukana kwabwino kwambiri kwa kukanda. Pakakhala madzi, mafuta ndi zinthu zina zonyowetsa, kukana kwa ma polyurethane casters kumakhala kochulukirapo kangapo kuposa kwa zipangizo wamba za rabara.

3. Njira zosiyanasiyana zopangira ndi kugwiritsa ntchito kwakukulu. Polyurethane elastomer imatha kupangidwa pogwiritsa ntchito njira ya pulasitiki, kusakaniza ndi vulcanizing (kutanthauza MPU); ikhozanso kupangidwa kukhala rabara yamadzimadzi, kupanga kapena kupopera, kuyika mumphika ndi kupanga centrifugal (kutanthauza CPU); ikhozanso kupangidwa kukhala zinthu zopyapyala ndikupangidwa ndi jakisoni, extrusion, calendering, blow molding ndi njira zina (kutanthauza CPU).
4. Yolimba ku mafuta, ozoni, ukalamba, kuwala kwa dzuwa, kutentha kochepa, kutulutsa mawu bwino, mphamvu yamphamvu yomatira, kugwirizana bwino kwa zamoyo komanso kugwirizana kwa magazi.

Komabe, ma elastomer a polyurethane ali ndi zovuta zina, monga kutentha kwambiri kwachilengedwe, kukana kutentha kwambiri, makamaka kukana chinyezi ndi kutentha, kukana ku solvents amphamvu a polar ndi acid ndi alkali media amphamvu.
