No ke aha ʻaʻole paʻa nā pahu polyurethane ke waiho ʻia no ka manawa lōʻihi

Nīnau pinepine nā mea kūʻai mai iā mākou i nā casters polyurethane i hoʻonoho ʻia no ka manawa lōʻihi, hiki ke ʻelemakule, maʻalahi ke wāwahi a me nā mea ʻē aʻe, ʻoiaʻiʻo, ʻaʻole kēia he pilikia caster, he mea maʻamau.

ʻO ka mea mua, polyurethane caster kumu kahiko
He ʻokoʻa nā kumu ʻelemakule o ka polyurethane caster. ʻO ka mea maʻamau, ʻo nā kumu nui o ka polyurethane caster aging e pili ana i ka oxidation, ultraviolet radiation, humidity, high temperature, low temperature, chemical solvents a me nā mea ʻē aʻe o ke kaiapuni, a me ke kaulahao polymer molecular o kona ʻano ponoʻī a me ke kūpaʻa kemika a me nā mea ʻē aʻe.

ʻO ka lua, ka hopena kahiko o ka polyurethane caster
ʻO ka ʻelemakule polyurethane caster, e hoʻololi ʻia kona mau kino kino a me nā mea kemika, i hōʻike ʻia e like me ke kala ʻeleʻele, ka haki ʻana o ka ʻili, ka emi ʻana o ka paʻakikī, ka emi ʻana o ka elasticity. Me ka hoʻonui ʻana o ke kiʻekiʻe o ka ʻelemakule, e nalowale ka hana o nā casters polyurethane i ka hana, a laila e alakaʻi i ka hemahema o ka waiwai. Ma nā noi kūpono, e like me ke kūkulu ʻana i nā mea hoʻopaʻa paʻa, nā huahana ʻili kūlohelohe, nā noho kaʻa a me nā māla ʻē aʻe, hiki i nā pahu polyurethane kahiko ke alakaʻi i nā pōʻino palekana.

ʻO ke kolu, inā ʻo ka ʻelemakule polyurethane e alakaʻi i ka palupalu o nā mea
Ma hope o ka ʻelemakule polyurethane caster, e emi ana ka paʻakikī a me ka elasticity o ka mea, hiki ke alakaʻi i ka palupalu o ka mea, akā ʻaʻole kēia wale ke ala o ka ʻelemakule. No ka laʻana, ʻo ka emi ʻana o nā waiwai paʻa o nā casters polyurethane hiki ke alakaʻi i ka deformation o ka mea ma lalo o ka ikaika. ʻOiaʻiʻo, hoʻololi nā hōʻailona hana kino e like me ka paʻakikī a me ka elasticity o nā casters polyurethane ma mua a ma hope o ka ʻelemakule, ʻo ia kekahi o nā hōʻailona koʻikoʻi o ka pae o ka ʻelemakule.
