High density Polyethylene Injection Molding Grade
ʻO HDPE kahi resin thermoplastic non-polar nui loa i hana ʻia ma o ka copolymerization o ka ethylene a me kahi mea liʻiliʻi o ka α-olefin monomer.Hoʻohui ʻia ʻo HDPE ma lalo o ke kaomi haʻahaʻa a no laila ua kapa ʻia ʻo polyethylene haʻahaʻa haʻahaʻa.ʻO ka HDPE ka nui o ke ʻano molekula laina a he liʻiliʻi ka lālā.Loaʻa iā ia kahi kiʻekiʻe o ka crystallization a me ke kiʻekiʻe kiʻekiʻe.Hiki iā ia ke pale i nā wela kiʻekiʻe a loaʻa ka rigidity maikaʻi a me ka ikaika mechanical a me ka anti-chemical corrosion.
ʻO ka papa hoʻoheheʻe ʻia ʻo HDPE he kaulike maikaʻi o ka rigidity a me ka paʻakikī, ka hopena maikaʻi a me ka maikaʻi o ka haʻahaʻa haʻahaʻa haʻahaʻa a me ka maikaʻi o ke koʻikoʻi kaiapuni.ʻO ka resin ka rigidity maikaʻi a me ke kū'ē abrasion, a me ka processability maikaʻi.
Pono e mālama ʻia ka resin i loko o kahi waihona maloʻo a maloʻo a mamao i ke ahi a me ka lā pololei.ʻAʻole pono e hoʻahu ʻia ma ka lewa ākea.I ka wā o ka halihali ʻana, ʻaʻole pono e ʻike ʻia ka mea i ka lā ikaika a i ʻole ka ua a ʻaʻole pono e lawe pū ʻia me ke one, lepo, metala ʻōpala, lanahu a aniani paha.ʻAʻole loa e pāpā ʻia ka lawe ʻana me nā mea ʻawaʻawa, corrosive a me ke ahi.

Hoʻohana ʻia ʻo HDPE injection-molding grade no ka hana ʻana i nā ipu e hiki ke hoʻohana hou ʻia, e like me nā pahu pia, nā mea inu, nā hihia meaʻai, nā hihia mea kanu a me nā hihia hua manu a hiki ke hoʻohana ʻia no ka hana ʻana i nā pā palaka, nā ipu waiwai, nā mea pono home, nā waiwai o kēlā me kēia lā a me ka lahilahi. pā ʻai meaʻai.Hiki ke hoʻohana ʻia i ka hana ʻana i nā barela hoʻohana ʻoihana, nā ʻōpala a me nā mea pāʻani.Ma o ke kaʻina hana extrusion a me ka hoʻoheheʻe ʻana a me ka hoʻoheheʻe ʻana, hiki ke hoʻohana ʻia e hana i nā pāpale o ka wai i hoʻomaʻemaʻe ʻia, ka wai mineral, ka inu kī a me nā hue inu wai.
