Kū ʻo UHMW-PE no Ultra High Molecular Weight Polyethylene.ʻO ia ka polyethylene (PE) kiʻekiʻe kiʻekiʻe loa i loaʻa, i hana ʻia no nā hana paʻakikī a me kahi ākea o nā noi.
Hāʻawi ia i ka mālama kālā ma kekahi mau noi paʻakikī.ʻO Ultra High Molecular Weight ka mea huna o nā waiwai kūʻokoʻa o kēia polymer.ʻO kāna polyethylene resin kiʻekiʻe he ʻano kaumaha molekala o 3 a 6 miliona, hoʻohālikelike ʻia me 300,000 a 500,000 no nā resins molecular weight (HMW).ʻO kēlā ʻokoʻa ka mea e hōʻoia ai i ka ikaika o kēia mea e pale aku i ka abrasion a me ka hopena ʻoi aku ka maikaʻi ma mua o nā huahana poly haʻahaʻa haʻahaʻa.ʻO ke kaumaha molekala kiʻekiʻe o UHMW-PE ʻaʻole ia e hoʻoheheʻe ʻia a kahe ʻole e like me ka wai hoʻoheheʻe.No laila, loaʻa nā ʻano hana mai nā ʻenehana metala pauka.ʻAʻole hiki ke hoʻololi a hoʻoheheʻe ʻia ka UHMW-PE e nā ʻenehana hana plastik maʻamau (hoʻoheheʻe injection, hoʻoheheʻe ʻana a i ʻole thermoforming).ʻO ka hoʻoheheʻe ʻana ʻo ia ke kaʻina hoʻololi maʻamau i hoʻohana ʻia me kēia resin no ka mea e hoʻopuka ana i kahi huahana ikaika a paʻa.
Ua ʻike ʻia ʻo UHMW no kona kūpaʻa abrasion kiʻekiʻe, ka lubrication kūlohelohe, ka ikaika hopena kiʻekiʻe, kemika-, corrosion-, a me ka moisture-kū'ē a me ka acoustic impedance.
Ma muli o kona abrasion-, corrosion-, chemical- and moisture-resistant properties, hoʻohana mau ʻia ʻo UHMW i nā noi inā ʻoi aku ka paʻakikī o nā kūlana no nā mea ʻē aʻe.He polymer hana kiʻekiʻe ke kumu kūʻai i hoʻohana ʻia e hana i nā kumu kūʻai haʻahaʻa, nā ʻāpana kiʻekiʻe.
ʻO UHMW kahi mea lubricating ponoʻī e hōʻike ana i ka lole a me nā waiwai abrasion a me ka hoʻohui ʻana i ka ikaika hopena kiʻekiʻe.ʻO kekahi o nā mākeke e hoʻohana i kēia mau hiʻohiʻona, ʻo ia ka lalo o ka snowboard, ka mālama ʻana i ka ʻeke, ka hoʻopili ʻana, ka hana ʻai a me nā kaʻa.
ʻO ke kaumaha molekala kiʻekiʻe ka mea e hāʻawi ai iā UHMW-PE kahi hui kūʻokoʻa o ka ikaika hopena kiʻekiʻe e kūpono i ka friction a me ke kūpaʻa abrasion e ʻoi aku ka maikaʻi ma mua o ke kila kalapona 10 a hiki i ka 1 e kūpono ai i nā noi kahi i hāʻule ʻole ai nā māka kaumaha molekala haʻahaʻa.
ʻEkolu hoʻokolohua hiki iā ʻoe ke hana:
- Hoʻāʻo Burn - e hoʻā me ka pāʻani a honi i ka uahi.Inā honi ia e like me ke kukui kukui - hōʻike ia i ka polyethylene.ʻAʻole kulu ʻo UHMW e like me ka HDPE akā e kulu.
- Oven Test - waiho ia i loko o kahi pā alumini i loko o ka umu 300 degere.E hāʻule a heheʻe paha ka HDPE maʻamau akā ʻaʻole e loli ka UHMW i ka nui a i ʻole ke ʻano.Eia nō naʻe, hiki ke hoʻololi a hoʻololi paha ma muli o ke koʻikoʻi i kūkulu ʻia.
Hōʻike ʻike - Ke ʻoki ʻia me ka ʻili, hāʻawi ka HDPE maʻamau i ka ʻōpala a i ʻole nā faila a ʻo UHMW e hāʻawi i nā kaula a i ʻole.
