E noʻonoʻo i nā pono a me nā pōʻino ʻole o nā mea hoʻolele polyurethane iron core

ʻO ka hao hao polyurethane caster he ʻano mea hoʻoheheʻe me nā mea polyurethane, i hoʻopaʻa ʻia e hoʻolei i ke kumu hao, ke kila kila a i ʻole ke kila kila, ʻo ia ka mālie, ke kaumaha lohi a me ka waiwai, a kūpono no ka hapa nui o nā kaiapuni.
ʻO ka maʻamau, ʻo ka nui o nā casters ʻoihana ma waena o 4 ~ 8 iniha (100-200mm), me nā huila polyurethane ka mea maikaʻi loa. ʻO nā huila Polyurethane he ʻoi aku ka maikaʻi o ka abrasion, kahi ākea o ka hana hiki ke hoʻololi ʻia, nā ʻano hana like ʻole, ka hoʻohana ākea, a me ke kūpaʻa maikaʻi i ka aila, ozone, ʻelemakule, radiation, haʻahaʻa haʻahaʻa, a me nā mea ʻē aʻe. pili koko.

Hōʻike nui ʻia nā casters polyurethane e nā hiʻohiʻona aʻe:
1. Nui hiki ke hoʻololi i ka hana. Ma o ke koho ʻana i nā mea maka a me ka hoʻoponopono ʻana i ke ʻano, hiki ke maʻalahi i loko o kahi ʻano o nā hoʻololi i kekahi mau hōʻailona hana kino a me ka mechanical, e hoʻokō i nā koi kūikawā o ka mea hoʻohana i ka hana o nā huahana. No ka laʻana, hiki ke hana ʻia nā elastomers polyurethane i loko o nā wili paʻi paʻi palupalu a me nā wili kila paʻakikī e hoʻokō i nā pono o nā mea hoʻohana like ʻole.
2. Ke kū'ē abrasion kiʻekiʻe. Ma ke alo o ka wai, ka aila a me nā ʻano hana hoʻomaʻemaʻe ʻē aʻe, ʻoi aku ka nui o ka pale ʻana o nā casters polyurethane i nā manawa he nui i nā manawa he nui o nā mea lāʻau maʻamau.

3. Nā ʻano hana like ʻole a me ka hoʻohana ākea. Hiki ke hoʻoheheʻe ʻia ka polyurethane elastomer e ka plasticizing, ka hui ʻana a me ka hana vulcanizing (e pili ana i ka MPU); hiki ke hana ʻia i ʻōpala wai, ka hoʻoheheʻe ʻana a i ʻole ka hoʻoheheʻe ʻana, ka potting a me ka centrifugal molding (e pili ana i ka CPU); hiki ke hana ʻia i mea granular a hoʻoheheʻe ʻia e ka injection, extrusion, calendering, blow molding a me nā kaʻina hana ʻē aʻe (e pili ana i ka CPU).
4. Kū'ē i kaʻaila, ka ozone, kaʻelemakule, ka radiation, ka haʻahaʻa haʻahaʻa, ka hoʻouna kani maikaʻi, ka ikaika pipili ikaika, ka biocompatibility maikaʻi a me ka pili koko.

Eia naʻe, loaʻa i nā polyurethane elastomers kekahi mau hemahema, e like me ka wela endogenous kiʻekiʻe, ke kūpaʻa kiʻekiʻe o ka wela ma ka laulā, ʻoi aku ka maikaʻi o ka pale ʻana i ka makū a me ka wela, ʻaʻole kūʻē i nā mea hoʻoheheʻe polar ikaika a me ka waikawa ikaika a me ka media alkali.
