ʻO ka ikaika o ka polyamide fiber he 1-2 mau manawa kiʻekiʻe ma mua o ka pulupulu, 4-5 mau manawa kiʻekiʻe ma mua o ka hulu hipa, a he 3 mau manawa kiʻekiʻe ma mua o ka viscose fiber.Eia nō naʻe, ʻilihune ka pale wela a me ka pale māmā o ka fiber polyamide, a ʻilihune hoʻi ka paʻa.ʻAʻole maʻemaʻe nā lole i hana ʻia me ka fiber polyamide e like me nā lole i hana ʻia me ka fiber polyester.Eia kekahi, ʻo ka nylon - 66 a me ka nylon - 6 i hoʻohana ʻia no ka lole i nā hemahema o ka hoʻomaʻamaʻa maikaʻi ʻole a me ke kala.No laila, ua hoʻomohala ʻia kahi ʻano hou o ka fiber polyamide, ka polyamide fiber hou o nylon - 3 a me nylon - 4.Loaʻa iā ia nā hiʻohiʻona o ke kaumaha māmā, ke kūpaʻa wrinkle maikaʻi, ka permeability maikaʻi o ka ea, ka lōʻihi maikaʻi, ka waihoʻoluʻu a me ka hoʻonohonoho wela, etc., no laila ua manaʻo ʻia he mea hoʻohiki loa.
Hoʻohana nui ʻia kēia ʻano huahana.He mea maikaʻi ia e hoʻololi i ke kila, ka hao, ke keleawe a me nā metala ʻē aʻe me nā plastik.He mea ko'iko'i 'enekinia plastic;Hoʻohana nui ʻia ʻo Cast nylon e hoʻololi i nā ʻāpana kūʻokoʻa o nā mea hana mechanical a me ke keleawe a me ka alloy ma ke ʻano he mau ʻāpana kūʻokoʻa o nā lako.He kūpono ia no ka hana ʻana i nā ʻāpana pale ʻaʻahu, nā ʻāpana hoʻoili hoʻoili, nā ʻāpana uila hale, nā ʻāpana hana kaʻa, nā ʻāpana mechanical prevention rod, nā ʻāpana mīkini a me nā mea kemika.E like me ka turbine, gear, bearing, impeller, crank, instrument panel, drive shaft, valve, blade, screw rod, high-press washer, screw, nut, seal ring, shuttle, sleeve, shaft sleeve connector, etc.
