Hoʻopuka ʻo Tongxiang i nā ʻano kiʻekiʻe kiʻekiʻekāʻei conveyor idler rollers, e hoʻokomo i ka ʻōwili HDPE. Aia kahi hoʻolauna pōkole o nā mea hdpe.
ʻO HDPE ka pōkole o ka polyethylene kiʻekiʻe kiʻekiʻe, ʻo ia ka polyolefin thermoplastic i hana ʻia e ka copolymerization o ka ethylene. ʻO HDPE kahi mea waxy keʻokeʻo opaque.ʻOi aku ka māmā ma mua o ka wai, palupalu a paʻakikī, akā ʻoi aku ka paʻakikī ma mua o LDPE.
He ʻano liʻiliʻi nō hoʻi, ʻaʻohe mea ʻawaʻawa a ʻono ʻole.He huahana ia o ka polymerization ma lalo o nā kūlana haʻahaʻa haʻahaʻa i hoʻopili ʻia e Ziegler catalyst, no laila ua kapa ʻia ka polyethylene kiʻekiʻe kiʻekiʻe ka polyethylene haʻahaʻa haʻahaʻa. mahele, a me na mea hoohui.Hoʻohana ʻia nā catalysts e hana i ka polymer kūikawā.Hoʻohui kēia mau mea hoʻololi e hana i nā māka HDPE no nā hoʻohana like ʻole;
Nā pōmaikaʻi o ka HDPE:
1. He kūpaʻa maikaʻi loa ka HDPE i ka hapa nui o nā kemika home a me nā ʻoihana.He kūpaʻa ia i ka corrosion a me ka hoʻoheheʻe ʻia e nā oxidants ikaika, nā paʻakai acid-base a me nā solvents organik.
2. ʻAʻole hygroscopic ka HDPE a loaʻa iā ia nā waiwai wai a me ka mahu.Hiki ke hoʻohana ʻia no ka moisture proof, anti-seepage a i ʻole hoʻopili.

3. He mau waiwai uila ko HDPE, ʻoi aku ka ikaika dielectric kiʻekiʻe, e kūpono ana ia no ka uea a me ke kaula.ʻOi aku ka maikaʻi o ke kūpaʻa ʻana o nā māka kaumaha molekala waena a me ke kiʻekiʻe, ma nā mahana ambient a me nā haʻahaʻa haʻahaʻa o -40F.
4. He maikaʻi ke kaʻina hana a me ka wela o ka HDPE.
5. He kiʻekiʻe kiʻekiʻe ka HDPE o ka pepa, ʻoʻoleʻa a me ka wehe ʻana, ʻo ka paʻakikī he 4 a 5 mau manawa o ka kiʻiʻoniʻoni LDPE.ʻO kona paʻakikī o ka ʻili, ka ikaika tensile, rigidity a me nā ikaika mechanical ʻē aʻe kokoke i PP, ʻoi aku ka paʻakikī ma mua o PP.
6. ʻO ka HDPE he meaʻawaʻawaʻole a me kaʻalaʻole, hiki ke hoʻohanaʻia no ka meaʻai, nā lole, nā lole lole a me nā mea hoʻopili'ē aʻe, ka waiwai.
ʻO nā hemahema o ka HDPE:
1. ʻAʻole maikaʻi kona kūpaʻa ʻelemakule a me ke koʻikoʻi o ke kaiapuni e like me LDPE, ʻoi aku ka maikaʻi o ka oxidation thermal i kāna hana.No laila, hoʻohui ʻia ka polyethylene kiʻekiʻe me ka anti-oxidant a me ka UV absorber i mea e lawa ʻole ai ke hana ʻia i loko o ka ʻili plastik.Mahea.
2. He ha'aha'a ko ka HDPE a me ka pale 'ole i ka oxygen a me nā kinoea 'ē a'e.
3. paʻakikī e paʻi, i ka paʻi ʻana, pono ka mālama ʻana i ka hoʻokuʻu ʻana o ka ʻili, ʻaʻole hiki ke electroplated, ʻeleʻele ka ʻili.
ʻo mākounā mea hana wili uila a me nā mea hoʻolako, inā makemake ʻoe, e hoʻokaʻaʻike mai iā mākou.
