Unikani ubwino ndi kuipa kwa mafakitale iron core polyurethane casters

Iron core polyurethane caster ndi mtundu wa caster wokhala ndi zinthu za polyurethane, zomangirizidwa ku chitsulo chapakati, pachimake chachitsulo kapena pachimake chachitsulo, chomwe chimakhala chete, cholemera pang'onopang'ono komanso chopanda ndalama, ndipo ndichoyenera malo ambiri ogwirira ntchito.
Nthawi zambiri, kukula kwa makina opangira mafakitale kumakhala pakati pa 4 ~ 8 mainchesi (100-200mm), ndi mawilo a polyurethane kukhala abwino kwambiri. Mawilo a polyurethane ali ndi kukana kwamphamvu kwa abrasion, magwiridwe antchito osiyanasiyana osinthika, njira zosiyanasiyana zosinthira, kugwiritsa ntchito bwino, komanso kukana mafuta, ozoni, ukalamba, ma radiation, kutentha pang'ono, etc., permeability wabwino, zomatira zolimba, biocompatibility yabwino komanso kuyanjana kwa magazi.

Polyurethane casters imadziwika ndi izi:
1. Large chosinthika osiyanasiyana ntchito. Kupyolera mu kusankha zipangizo ndi kusintha chilinganizo, akhoza kusinthasintha mkati osiyanasiyana kusintha mu chiwerengero cha thupi ndi makina ntchito zizindikiro, kukwaniritsa zofunika zapadera za wosuta pa ntchito mankhwala. Mwachitsanzo, ma elastomers a polyurethane amatha kupangidwa kukhala zodzigudubuza zofewa zosindikizira ndi zitsulo zolimba kuti zikwaniritse zosowa za ogwiritsa ntchito osiyanasiyana.
2. Kukana kwapamwamba kwa abrasion. Pamaso pa madzi, mafuta ndi zina zonyowetsa media zogwirira ntchito, kukana kwa ma polyurethane casters kumakhala kangapo kambirimbiri kuposa kwa zida wamba zalabala.

3. Zosiyanasiyana processing njira ndi applicability lonse. Polyurethane elastomer ikhoza kupangidwa ndi plasticizing, kusakaniza ndi vulcanizing ndondomeko (amatanthauza MPU); imathanso kupangidwa kukhala mphira wamadzimadzi, kuponyera kapena kupopera mbewu mankhwalawa, poto ndi centrifugal akamaumba (amatanthauza CPU); imathanso kupangidwa kukhala zinthu zagranular ndikuwumbidwa ndi jekeseni, extrusion, calendering, kuwomba ndikuwumba ndi njira zina (zikutanthauza CPU).
4. Kugonjetsedwa ndi mafuta, ozoni, ukalamba, kuwala kwa dzuwa, kutentha pang'ono, kufalitsa kwabwino kwa mawu, mphamvu zomatira zolimba, biocompatibility yabwino komanso kuyanjana kwa magazi.

Komabe, polyurethane elastomers ndi kuipa zina, monga mkulu amkati kutentha, mkulu kutentha kukana ambiri, makamaka zoipa kukana chinyezi ndi kutentha, osati kugonjetsedwa ndi zosungunulira amphamvu polar ndi asidi amphamvu ndi alkali TV.
