ʻO Polyoxymethylene (POM) he ʻano palakika ʻenekinia me ka hana maikaʻi loa, i ʻike ʻia ma waho e like me "Duracon" a me "Super Steel". Loaʻa i ka POM pale ʻaʻahu kiʻekiʻe ka paʻakikī, ka ikaika a me ka paʻakikī e like me ka metala. Loaʻa iā ia ka lubrication ponoʻī maikaʻi, ka pale luhi maikaʻi a me ka elasticity i nā ʻano mahana a me ka haʻahaʻa. Eia kekahi, loaʻa iā ia ke kūpaʻa kemika maikaʻi. Ua hoʻolauna ʻo Ruiyuan Engineering Plastics i ka POM pale ʻaʻahu kiʻekiʻe ma ke kumukūʻai haʻahaʻa ma mua o nā plastik ʻenekinia ʻē aʻe he nui. Ke pani nei ia i kekahi mau mākeke i noho mau ʻia e nā metala, e like me ke pani ʻana i ka zinc, keleawe, alumini a me ke kila e hana i nā ʻāpana he nui. Mai kona wā i ʻike ʻia ai, ua hoʻohana nui ʻia ka POM pale ʻaʻahu kiʻekiʻe i nā mea uila, nā mīkini, ke ʻano, ka ʻoihana kukui o kēlā me kēia lā, nā kaʻa, nā mea kūkulu hale, ka mahiʻai a me nā ʻoihana ʻē aʻe. Ma nā ʻano noi hou he nui, e like me ka ʻenehana lapaʻau, nā lako haʻuki, a me nā mea ʻē aʻe, hōʻike pū ka POM pale ʻaʻahu kiʻekiʻe i kahi ʻano ulu maikaʻi.

Nā ʻano POM kūpaʻa kiʻekiʻe:

1. ʻO ka POM kūpaʻa kiʻekiʻe he palakika crystalline me kahi kiko heheʻe ʻokoʻa. Ke hiki i kahi kiko heheʻe, e emi koke ka mānoanoa heheʻe.

2. ʻO ka POM kūpaʻa kiʻekiʻe he haʻahaʻa loa ka coefficient friction a me ke kūpaʻa geometric maikaʻi, a kūpono loa ia no ka hana ʻana i nā kia a me nā bearings.

3. Loaʻa i ka POM kūpaʻa kiʻekiʻe ke kūpaʻa wela kiʻekiʻe, no laila hoʻohana ʻia ia i nā lako pipeline (nā valves pipeline, nā hale pamu), nā lako lawn, a pēlā aku.

4. He mea paʻakikī a palupalu ka POM kūpaʻa kiʻekiʻe, nona ke kūpaʻa kolo maikaʻi, kūpaʻa geometric a me ke kūpaʻa hopena ʻoiai i nā mahana haʻahaʻa.

5. ʻO ke kiʻekiʻe o ka crystallization o ka POM pale ʻaʻahu kiʻekiʻe e alakaʻi i kahi helu shrinkage kiʻekiʻe, hiki ke piʻi i ka 2% a i ka 3.5%. Aia nā helu pōkole like ʻole no nā ʻikepili i hoʻonui ʻia.
