Silicone masterbatchhe ʻano mea hoʻohui i loko o ka ʻoihana palaki a me ka plastic. ʻO ka ʻenehana holomua ma ke kahua o nā mea hoʻohui silicone ka hoʻohana ʻana i ka ultra-high molecular weight (UHMW) silicone polymer (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 e hiki ai ke hoʻohui maʻalahi i ka mea hoʻohui i ka thermoplastic i ka wā e hana ai. ka hoʻohui ʻana i ka hana maikaʻi loa me ka uku kūpono. He mea maʻalahi ka silicone masterbatch e hānai, a hui pū paha, i loko o nā plastics i ka wā e hui pū ai, extrusion, a i ʻole ka hoʻoheheʻe ʻana. ʻOi aku ka maikaʻi ma mua o ka ʻaila wax kuʻuna a me nā mea hoʻohui ʻē aʻe i ka hoʻomaikaʻi ʻana i ka paheʻe i ka wā hana. No laila, makemake nā mea hana plastic e hoʻohana iā lākou i ka hopena.

Nā kuleana oPākuʻi Silicone Masterbatchi ka hoʻomaikaʻi ʻana i ka hana ʻana i ka plastik

ʻO ka silicone masterbatch kekahi o nā koho kaulana loa no nā kaʻina hana i ka hana plastik a me ka hoʻomaikaʻi ʻana i ka maikaʻi o ka ʻili. E like me ke ʻano o ka lubricant super. Loaʻa iā ia nā hana nui ke hoʻohana ʻia i ka resin thermoplastic:

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

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

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

B. Hoʻomaikaʻi i nā waiwai ili o ka resin

E hoʻomaikaʻi i ka hoʻopau ʻana i ka ʻili o ka ʻili, hoʻomaʻemaʻe degere, a hoʻemi i ka coefficient friction o ka ʻili, hoʻomaikaʻi i ke kūpaʻa ʻaʻahu a me ka pale ʻana;

A ʻo ka silicone masterbatch maikaʻi ka thermal stability (thermal decomposition wela ma kahi o 430 ℃ i ka nitrogen) a me ka neʻe ʻole;

Palekana kaiapuni;

Pili palekana me ka meaʻai.

Pono mākou e kuhikuhi i nā hana silicone masterbatches a pau iā A a me B (ʻo nā helu ʻelua ma luna a mākou i helu ai) akā ʻaʻole lākou ʻelua mau wahi kūʻokoʻa akā.

hoʻopili kekahi i kekahi, a pili loa.

Nā hopena i nā huahana hope loa

Ma muli o nā hiʻohiʻona o ka molecular structure o siloxane, liʻiliʻi loa ka dosage no laila ʻaʻohe hopena i ka waiwai mechanical o nā huahana hope loa. ma ka ʻōlelo maʻamau, koe naʻe ka elongation a me ka ikaika hopena e piʻi iki, me ka ʻole o nā hopena i nā mea mekini ʻē aʻe. Ma kahi nui nui, he hopena synergistic ia me nā mea pale ahi.

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

ʻAno hana

ʻO nā papa hana silikoniʻO ka polysiloxane kaumaha ultra-kiʻekiʻe i hoʻopuehu ʻia i loko o nā resins halihali like ʻole he ʻano hana masterbatch. Ke kaumaha nui molekala kiʻekiʻesilicone masterbatcheshoʻohui ʻia i loko o nā plastics no kā lākou nonpolar a me ka ikehu haʻahaʻa o ka ʻili, he ʻano ia e neʻe i ka ʻili plastik i ka wā o ka hoʻoheheʻe ʻana; ʻoiai, no ka mea he nui kona kaumaha molekala, ʻaʻole hiki ke neʻe loa i waho. No laila, kapa mākou i ka lokahi a me ka lokahi ma waena o ka neʻe ʻana a me ka neʻe ʻole. Ma muli o kēia waiwai, ua hoʻokumu ʻia kahi papa lubrication ikaika ma waena o ka ʻili plastik a me ka wili.

Ke hoʻomau nei ka hana ʻana, lawe mau ʻia kēia papa lubrication a hana ʻia. No laila ke hoʻomaikaʻi mau nei ka kahe o ka resin a me ka hoʻoili ʻana a me ka hoʻohaʻahaʻa ʻana i ka uila uila, nā mea hana a me ka hoʻomaikaʻi ʻana i ka hopena. Ma hope o ka hana ʻana o ka māhoe-screw, e māhele like ʻia nā masterbatches silicone i loko o nā plastics a hoʻokumu i kahi ʻaila ʻaila 1 a 2-micron ma lalo o ka microscope, e hāʻawi kēlā mau ʻaila aila i nā huahana i kahi hiʻohiʻona maikaʻi, manaʻo lima maikaʻi, COF haʻahaʻa, a ʻoi aku ka nui. abrasion a me ke kuʻi 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 ʻo ka dispersibility ke kī kuhikuhi no nā masterbatches silicone, ʻo ka liʻiliʻi o nā ʻāpana, ʻoi aku ka hoʻohele ʻana, ʻoi aku ka maikaʻi o ka hopena. e loaʻa iā mākou.
