ʻO ka mīkini CNC ma PU
ʻO nā palakiko kekahi mea maʻamau i hoʻohana ʻia i ka huli ʻana CNC no ka mea loaʻa lākou i nā koho like ʻole, he ʻano pipiʻi ke kumu kūʻai, a he wikiwiki ka manawa hana. ʻO nā palakiko i hoʻohana pinepine ʻia e komo pū me ABS, acrylic, polycarbonate a me nylon.
Wehewehe ʻana o PU (Polyurethane)
He mea elastomeric maʻalahi ka PU i ʻike ʻia no kona maʻalahi, kūpaʻa, a me ke kūpaʻa kemika. Hoʻohana pinepine ʻia ia i nā noi e pono ai ka cushioning, insulation, a me ke kūpaʻa i ka hopena.

ʻIke ʻepekema kaulana e pili ana iā PU
He polymer maʻalahi a hiki ke hoʻololi ʻia ʻo PU (Polyurethane) i hoʻohana nui ʻia ma nā ʻoihana like ʻole. Hoʻokumu ʻia ia ma o ka hopena o nā diisocyanates me nā polyols, e hopena ana i kahi ākea o nā mea polyurethane me nā waiwai a me nā noi like ʻole.
Ua kaulana ʻo PU no kona kūpaʻa maikaʻi loa i ka ʻānai ʻana. Hiki iā ia ke kū i ka friction a me ke komo pinepine ʻana, e kūpono ai no nā noi e pono ai ke kūpaʻa, e like me nā ʻāpana mīkini ʻoihana, nā kāʻei conveyor, a me nā uhi no nā papahele a me nā ʻili.
He mea māmā ka PU, kahi e kūpono ai no nā noi kahi e makemake ʻia ai ka hōʻemi kaumaha. He haʻahaʻa kona density i hoʻohālikelike ʻia me nā mea ʻē aʻe, e like me nā metala a me ke aniani, ʻoiai e hāʻawi mau ana i ka ikaika a me ka hana like. ʻO kēia waiwai e hoʻolilo iā PU i koho kaulana no nā noi e pono ai ka ikaika a me nā ʻano māmā, e like me nā ʻāpana aerospace a me nā lako haʻuki.
Ua kaulana nō hoʻi ʻo PU no kona mau waiwai insulation thermal maikaʻi loa. He haʻahaʻa kona conductivity thermal, e lilo ia i mea insulator kūpono e kūʻē i ka wela a me ke anu. ʻO kēia waiwai e kūpono ai ʻo PU no nā noi e pono ai ka insulation thermal, e like me ka insulation hale, ka refrigeration, a me ka thermal packaging.
