Hoʻohana mau ʻia nā dispersants a me nā lubricants i nā mea hoʻohui i ka hoʻohālikelike ʻana i ka waihoʻoluʻu plastic.Inā hoʻohui ʻia kēia mau mea hoʻohui i nā mea maka o ka huahana, pono lākou e hoʻohui ʻia i ka resin raw material i ka like like i ka hōʻoia ʻana o ka kala, i mea e pale ai i ka ʻokoʻa kala i ka hana ma hope.
ʻO nāʻano o nā mea hoʻopuehu: polyureas momona momona, base stearate, polyurethane, kopa oligomeric, a me nā mea'ē aʻe.Loaʻa i nā lubricants nā waiwai hoʻopuehu maikaʻi, a hiki ke hoʻomaikaʻi i ka wai a me ka hoʻokuʻu ʻana i nā waiwai o nā plastics i ka wā e hoʻoheheʻe ʻia.
Hoʻokaʻawale ʻia nā lubricants i nā lubricants i loko a me nā lubricants waho.Loaʻa i nā lubricants i loko kahi kūpono me nā resins, hiki ke hōʻemi i ka cohesion ma waena o nā kaulahao mole mole resin, hoʻemi i ka viscosity melt, a hoʻomaikaʻi i ka wai.ʻO ka hoʻohālikelike ma waena o ka lubricant waho a me ka resin, pili ia i ka ʻili o ka resin i hoʻoheheʻe ʻia e hana i kahi papa mole lubricating, a laila e hōʻemi i ka friction ma waena o ka resin a me nā mea hana.Hoʻokaʻawale nui ʻia nā Lubricants i nā ʻāpana aʻe e like me ko lākou ʻano kemika:
(1)) Papa puhi e like me ka paraffin, polyethylene wax, polypropylene wax, micronized wax, etc.
(2) ʻO nā ʻakika momona e like me ka waikawa stearic a me ka waikawa stearic kumu.
(3) Fatty acid amides, esters like vinyl bis-stearamide, butyl stearate, oleic acid amide, etc. Hoʻohana nui ia no ka hoʻopuehu ʻana, kahi i hoʻohana ʻia ai ka bis-stearamide no nā thermoplastics a me nā plastic thermosetting, a he hopena lubricating. .
(4) ʻO nā kopa metala e like me ka stearic acid, zinc stearate, calcium stearate, pot stearate, magnesium stearate, lead stearate, a me nā mea ʻē aʻe i loaʻa nā hopena wela a me ka lubricating.
(5) ʻO nā lubricants e pāʻani ana i ka hoʻokuʻu ʻana i ka mold, e like me ka polydimethylsiloxane (methyl silicone oil), polymethylphenylsiloxane (phenylmethyl silicone oil), polydiethylsiloxane (ethyl silicone oil) etc.
I ke kaʻina hana hoʻoheheʻe, i ka wā e hoʻohana ʻia ai ke kala maloʻo, hoʻohui pinepine ʻia nā mea lapaʻau e like me ka ʻaila mineral keʻokeʻo a me ka ʻaila diffusion i ka wā e hui pū ai e pāʻani i ke ʻano o ka adsorption, lubrication, diffusion a me ka hoʻokuʻu ʻana.I ke kala ʻana, pono e hoʻohui pū ʻia nā mea maka i ka hoʻolaha ʻana i ke kala.E hoʻohui mua i ka mea lapaʻau ma luna a palahalaha like, a laila e hoʻohui i ka toner a pālahalaha like.
I ke koho ʻana, pono e hoʻoholo ʻia ka pale wela o ka dispersant e like me ka mahana hoʻoheheʻe ʻana o ka mea palaka.Mai ka hiʻohiʻona o ke kumukūʻai, ma ke kumu, ʻaʻole pono e koho ʻia ka dispersant i hiki ke hoʻohana ʻia i ka mahana wela a me ka haʻahaʻa no ke kūpaʻa wela kiʻekiʻe.Pono ka dispersant wela kiʻekiʻe e kū i luna o 250 ℃.
