He aha ka ʻokoʻa ma waena o ka pā UHMWPE a me ka pā PTFE?

ʻO ka pā UHMWPE a me ka pā PTFE ʻelua i hoʻohana nui ʻia i nā plastic non-metallic ma ka mākeke.ʻO nā hiʻohiʻona maʻamau o nā mea ʻelua he ʻenekinia palaka me ka pale ʻana i ka corrosion, ka lubrication ponoʻī a me ka coefficient friction haʻahaʻa.Hōʻike nā hiʻohiʻona like ʻole ʻoi aku ka maikaʻi o ka pā UHMWPE ma mua o ka pā PTFE, akā ʻaʻole maikaʻi ke kūpaʻa kiʻekiʻe e like me ka pā PTFE.A laila, e hōʻuluʻulu au i nā ʻokoʻa nui ma waena o nā mea ʻelua.

UHMWPE pā a meʻO ka pā PTFEi kēia manawa ʻelua i hoʻohana nui ʻia nā plastic non-metallic ma ka mākeke.ʻO nā hiʻohiʻona maʻamau o nā mea ʻelua he ʻenekinia palaka me ka pale ʻana i ka corrosion, ka lubrication ponoʻī a me ka coefficient friction haʻahaʻa.Hōʻike nā hiʻohiʻona like ʻole ʻoi aku ka maikaʻi o ka pā UHMWPE ma mua o ka pā PTFE, akā ʻaʻole maikaʻi ke kūpaʻa kiʻekiʻe e like me ka pā PTFE.A laila, e hōʻuluʻulu au i nā ʻokoʻa nui ma waena o nā mea ʻelua.

1. Wear resistance: He maikaʻi loa ka pale lole UHMWPE, ʻoi aku ka kiʻekiʻe o ke kaumaha molekala, ʻoi aku ka maikaʻi o ka pale ʻana o ka mea.2. ʻO ke koena friction: no ka mea, loaʻa iā UHMWPE nā waiwai hoʻoluʻu ponoʻī.No laila, hiki iā ia ke hana i ke ʻano sliding a i ʻole ka ʻōwili ʻana me ka ʻole o ka ʻaila lubricating, ʻoi aku ka maikaʻi ma mua o ke kila a me ke keleawe i nā kūlana lubricating.

3. Ka nui o ka hoʻoheheʻe wai o nā mea: ʻO ka pā UHMWPE he haʻahaʻa haʻahaʻa loa.ʻAʻole hiki ke komo i ka wai, ʻaʻole pehu i ka wai, a ʻoi aku ka liʻiliʻi ma mua o ka nylon.4. Ke kū'ē kemika: He kiʻekiʻe kemika o ka pā UHMWPE, a hiki ke kū i ka hana o nā media corrosive like ʻole (acid, alkali, paʻakai) a me nā mea hoʻoheheʻe kūlohelohe e like me ka waikawa, ka alkali, ka paʻakai, a me nā mea ʻē aʻe i loko o kahi ʻano wela a me ka pae hoʻopaʻa.

5. ʻAʻohe mea ʻawaʻawa: ʻO ka pā UHMWPE he mea ʻala ʻole, ʻaʻohe mea ʻawaʻawa, ʻaʻala ʻole, ʻaʻohe corrosive, a loaʻa iā physiological cycling a physiological adaptability.ʻO ka US Food and Drug Administration (FDA) a me ka United States Department of Agriculture (USDA) e ʻae iā ia e hoʻohana ʻia Hoʻohana ʻia i nā manawa e pili ana i ka meaʻai a me ka lāʻau lapaʻau, no laila kūpono ia no nā ʻoihana e koi ana i ka maʻemaʻe kiʻekiʻe. nā kūlana e like me ka meaʻai a me ka lāʻau lapaʻau.
