ʻO ka masterbatch siliconehe ʻano mea hoʻohui i loko o ka ʻoihana laholio a me ka palakiko. ʻO ka ʻenehana holomua i ke kahua o nā mea hoʻohui silicone ka hoʻohana ʻana i ka polymer silicone kaumaha molekala ultra-kiʻekiʻe (UHMW) (PDMS) i nā resins thermoplastic like ʻole, e like me LDPE, EVA, TPEE, HDPE, ABS, PP, PA6, PET, TPU, HIPS, POM, LLDPE, PC, SAN, etc. A ma ke ʻano he pellets i mea e maʻalahi ai ka hoʻohui pololei ʻana o ka mea hoʻohui i ka thermoplastic i ka wā e hana ana. e hoʻohui ana i ka hana maikaʻi loa me ke kumukūʻai kūpono. He maʻalahi ka hānai ʻana i ka masterbatch silicone, a i ʻole e hui pū, i loko o nā plastics i ka wā e hui pū ai, extrusion, a i ʻole ka hoʻoheheʻe ʻana i ka injection. ʻOi aku ka maikaʻi ma mua o ka ʻaila wax kuʻuna a me nā mea hoʻohui ʻē aʻe i ka hoʻomaikaʻi ʻana i ka slippage i ka wā e hana ai. No laila, makemake nā mea hana plastik e hoʻohana iā lākou i ka hopena.

Nā Kuleana oMea hoʻohui silicone Masterbatchi ka hoʻomaikaʻi ʻana i ka hana ʻana i ka palakiko

ʻO ka silicone masterbatch kekahi o nā koho kaulana loa no nā mea hana i ka hana plastik a me ka hoʻomaikaʻi ʻana i ka maikaʻi o ka ʻili. Ma ke ʻano he ʻano lubricant super. Loaʻa iā ia nā hana nui i ka wā e hoʻohana ʻia ai i ka resin thermoplastic:

A. Hoʻomaikaʻi i ke kahe o ka resin a me ka hana ʻana;

ʻOi aku ka maikaʻi o ka hoʻopiha ʻana i ka ʻōpala a me nā waiwai hoʻokuʻu ʻōpala

E ho'ēmi i ka torque extrude a ho'omaika'i i ka helu extrusion;

B. Hoʻomaikaʻi i nā waiwai o ka ʻili o ka resin

Hoʻomaikaʻi i ka hoʻopau ʻana o ka ʻili plastik, laumania ke kēkelē, a hoʻemi i ke koina friction ʻili, Hoʻomaikaʻi i ke kū'ē ʻana i ke kapa a me ke kū'ē ʻana i ka ʻōpala;

A he kūpaʻa maikaʻi ka silicone masterbatch (ʻo ka mahana decomposition thermal ma kahi o 430 ℃ i loko o ka naikokene) a me ka neʻe ʻole ʻana;

Ka palekana o ke kaiapuni;

Ka pilina palekana me ka meaʻai.

Pono mākou e kuhikuhi aku ua pili nā hana masterbatches silicone āpau iā A a me B (nā helu ʻelua i luna a mākou i helu ai) akā ʻaʻole lāua he mau helu kūʻokoʻa ʻelua akā

hoʻohui kekahi i kekahi, a pili loa.

Nā hopena ma nā huahana hope loa

Ma muli o nā ʻano o ke ʻano molekala o ka siloxane, he liʻiliʻi loa ka nui o ka lāʻau lapaʻau no laila ma ke ʻano holoʻokoʻa ʻaʻohe hopena i ka waiwai mechanical o nā huahana hope loa. ma ke ʻano laulā, koe wale nō ka elongation a me ka ikaika o ka hopena e hoʻonui iki ʻia, me ka ʻole o nā hopena i nā waiwai mechanical ʻē aʻe. I ka nui o ka lāʻau lapaʻau, loaʻa iā ia kahi hopena synergistic me nā mea pale ahi.

Ma muli o kāna hana koʻikoʻi ma ke kūpaʻa wela kiʻekiʻe a me ka haʻahaʻa, ʻaʻohe ona hopena ʻaoʻao ma ke kūpaʻa wela kiʻekiʻe a me ka haʻahaʻa o nā huahana hope loa. ʻoiai e hoʻomaikaʻi ʻia ke kahe o ka resin, ka hana ʻana, a me nā waiwai o ka ʻili a e hoʻemi ʻia ka COF.

ʻAno hana

Nā ʻāpana haku siliconeʻO nā polysiloxane kaumaha molekala kiʻekiʻe loa i hoʻopuehu ʻia i loko o nā resins lawe like ʻole ʻo ia ke ʻano o ka masterbatch hana. Ke kaumaha molekala kiʻekiʻe loanā ʻāpana haku siliconeua hoʻohui ʻia i loko o nā plastics no ko lākou nonpolar a me ka ikehu ʻili haʻahaʻa, loaʻa iā ia ke ʻano e neʻe i ka ʻili plastic i ka wā o ke kaʻina hana hoʻoheheʻe; ʻoiai, ʻoiai he kaumaha molekala nui kona, ʻaʻole hiki ke neʻe loa i waho. No laila kapa mākou ia he lokahi a me ka lokahi ma waena o ka neʻe ʻana a me ka neʻe ʻole ʻana. ma muli o kēia waiwai, ua hoʻokumu ʻia kahi papa lubrication dynamic ma waena o ka ʻili plastic a me ka wili.

Me ka hoʻomau ʻana o ka hana ʻana, ke lawe mau ʻia nei a hana ʻia kēia papa lubrication. No laila ke hoʻomaikaʻi mau ʻia nei ke kahe o ka resin a me ka hana ʻana a ke hoʻemi nei i ke au uila, ka torque o nā lako a me ka hoʻomaikaʻi ʻana i ka hopena. Ma hope o ka hana ʻana o nā wili māhoe, e hoʻolaha like ʻia nā masterbatches silicone i loko o nā plastics a hana i kahi ʻāpana aila 1 a 2-micron ma lalo o ka microscope, e hāʻawi kēlā mau ʻāpana aila i nā huahana i kahi hiʻohiʻona maikaʻi, ka manaʻo lima maikaʻi, ka COF haʻahaʻa, a me ka pale ʻana i ka abrasion a me ke kahakaha ʻana.

Mai ke kiʻi hiki iā mākou ke ʻike e lilo ka silicone i mau ʻāpana liʻiliʻi ma hope o ka hoʻopuehu ʻia ʻana i loko o nā plastics, hoʻokahi mea e pono ai mākou e kuhikuhi aku, ʻo ka dispersibility ke kumu nui no nā masterbatches silicone, ʻo ka liʻiliʻi o nā ʻāpana, ʻo ka hoʻolaha like ʻana, ʻo ka hopena maikaʻi a mākou e loaʻa ai.
