ʻO Polyoxymethylene (POM) kahi ʻano polymer linear me ka ʻole o ke kaulahao ʻaoʻao, me ke kiʻekiʻe kiʻekiʻe a me ka crystallinity kiʻekiʻe, nona nā waiwai piha.ʻO ka hiʻohiʻona koʻikoʻi o kēia mea ʻo kona modulus elastic kiʻekiʻe, paʻakikī kiʻekiʻe a me ka rigidity.
ʻO ka POM he plastic crystalline me ka maikaʻi o ka wai i loko o ke kūlana hoʻoheheʻe.Hoʻopili nui ʻia kona viscosity e ka nui o ka shear rate.He mea ʻili ʻili ia,
Wahi a nā ʻano hana kemika o nā kaulahao mole, hiki ke hoʻokaʻawale ʻia ka polyoxymethylene i ka homopolymerization a me ka copolymerization.ʻO ka homopolymer he kiʻekiʻe kiʻekiʻe, crystallinity a me ka ikaika mechanical, ʻoiai ʻo ka copolymer he paʻa wela maikaʻi, hiki ke hoʻoheheʻe ʻia a me ke kūpaʻa a me ka alkaline.
Hoʻohana i ka POM
1. Mea hoʻouna maʻalahi, lima alakaʻi, mea hana kaʻa kaʻa, mea hana.
2. He kūpono loa ka POM no ka hana ʻana i nā pauma kaʻa, nā ʻāpana carburetor, nā paipu aila, nā kīwaha mana, nā bearings he ʻumi tausani kiʻekiʻe, nā kaʻa kaʻa, nā puʻupuʻu, nā lima, dashboard, nā mea hoʻokiʻekiʻe puka makani, nā mea hoʻololi uila, nā pale kāʻei palekana, a pēlā aku no nā kaʻa.ʻO ka hana ʻana i nā ʻāpana ʻaʻahu e like me ka shaft sleeve, gear a me sliding block ka ikaika o POM i hoʻololi ʻia.ʻAʻole liʻiliʻi kēia mau ʻāpana i ka metala, hoʻemi i ka nui o ka aila lubricating, a hoʻonui i ke ola lawelawe o nā ʻāpana.No laila, hiki iā lākou ke hoʻololi i ke keleawe, zinc a me nā metala ʻē aʻe e hana i nā bearings, gears, pull rods, etc.
