Moolelo oʻO nā mea hoʻohui Silicone / Silicone masterbatch / Siloxane masterbatcha pehea e hana ai i lokouea & uwea huiʻoihana?

Silicone additives me50% silicone polymer hanaHoʻopuehu ʻia i ka mea lawe e like me ka polyolefin a i ʻole ka mineral, me ke ʻano o ka granular a i ʻole ka pauka, i hoʻohana nui ʻia e like me ke kōkua ʻana i ka ʻoihana uea a me ke kelepona.ʻO nā huahana kaulana e like meSILOXANE MB50Hana ʻia ka series ma ke ʻano he lubricant a i ʻole rheological modifier i ka uea a me ka ʻoihana kelepona a ua hoʻolauna mua ʻia mai Dow Corning i ʻAmelika Hui Pū ʻIa i iwakālua mau makahiki i hala, a laila kaʻO SILICONE MASTERBATCH MB50ʻike ʻia ma ka mākeke me70% hana silicone polymerHoʻopuehu ʻia i loko o ka mea lawe e like me ka silica, me ke ʻano o ka granular pū kekahi, a laila ua ʻike ʻia nā huahana mai Chengdu Silike i ka mākeke mai ka makahiki 2004, me ka ʻike silicone mai 30-70% a me ka granular a i ʻole ka pauka.

Pono nā ʻāpana ʻenehana o ka silicone masterbatch pāʻoihana i kēia ʻike:

(1) Ke hana nei ma ke ʻano he lubricant a i ʻole rheological modifier, ʻo ka ʻike mai 5 a 50%

(2) Pono ka mea lawe me ka silicone a pono e noʻonoʻo ʻia ka substrate kumu nui o ka mea hoʻohana, me ka hōʻailona inoa polymer a me ka helu heheʻe o ka mea lawe, i hiki i nā mea hoʻohana ke kuhikuhi iā ia i ka wā e hoʻolālā ai i ke ʻano.Inā hoʻohana ʻia ka pauda mineral inorganic e like me ka mea lawe, pono e hōʻike ʻia ka inoa pauda.He mea koʻikoʻi ka keʻokeʻo a me ka maikaʻi o nā pauka inorganic no nā mea kūʻai aku, a pono e koho ʻia nā pauka keʻokeʻo a me ka micron e like me ka hiki no ka hana ʻana.

Ke hana ma ke ʻano he lubricants a i ʻole rheological modifiers

No ka mea polyethylene

E like me ka mea i ʻike ʻia, ʻike pinepine ʻia ke ʻano o ka "ʻili manō" i ka wā e hoʻokuʻu ai i ka polyethylene insulated a i ʻole sheathed wires a me nā kaula, ʻoi loa i ka wā e hoʻokuʻu ai i ka linear low-density polyethylene (LLDPE) a i ʻole ultra-low density polyethylene (ULDPE a i ʻole POE).ʻO nā mea polyethylene i hoʻopaʻa ʻia i hoʻokuʻu ʻia (inā he peroxide cross-linking a i ʻole silane cross-linking) i kekahi manawa e ʻike i ke ʻano "ʻili manō", ma muli o ka noʻonoʻo pono ʻole o ka ʻōnaehana lubrication i loko o ke ʻano mea.ʻO ka hoʻomaʻamaʻa honua i kēia manawa ʻo ka hoʻohui ʻana i ka nui o nā fluoropolymers i ke ʻano, akā kiʻekiʻe ke kumukūʻai a ua kaupalena ʻia ka noi.

Me ka liʻiliʻi okiʻekiʻe kiʻekiʻe molecular kaumaha silicone(0.1-0.2%) i ka polyethylene a i ʻole ka polyethylene cross-linked hiki ke pale pono i ka hana ʻana o ka "ʻili manō".I ka manawa like, me kāna hopena lubrication, hiki iā ia ke hōʻemi pono i ka torque extrusion e pale ai i ka hoʻokuʻu ʻana o ka kaʻa ma muli o ka overload.

ʻO ka Silicone i hoʻohana ʻia ma ke ʻano he lubricant, ma muli o kāna hoʻohui liʻiliʻi, pono e puʻunaue like ʻia i loko o ka mea i mea e hana ai i ka wā o ka hana.Ma muli o ka inertness kemika o ka silicone, ʻaʻole ia e hana kemika me nā mea i loko o ke ʻano.Manaʻo ʻia e hoʻohui like ka hale hana kelepona i ke silicone i loko o ke kaʻina hana granulation plasticizing e hoʻomaʻamaʻa i ka hoʻohana ʻana i ka hale hana uea.

No ka meaʻO nā pūhui uwea halogen free flame retardent(HFFR). 

Ma muli o ka loaʻa ʻana o ka nui o nā mea pale ahi (mineral pauka) i loko o nā pūhui uwea HFFR, kahi e hopena ai i ka viscosity kiʻekiʻe a me ka flowability maikaʻi ʻole i ka wā o ka hana ʻana;ʻO ka viscosity kiʻekiʻe ka mea paʻakikī i ke kaʻa e huki i ka wā extrusion, a ʻo ka maikaʻi ʻole o ka wai ka hopena i kahi liʻiliʻi o ke kāpili i hana ʻia i ka wā extrusion.No laila, i ka wā e hoʻokuʻu ai ka hale hana uwea i nā kaula halogen-free, ʻo 1/2-1/3 wale nō ka pono o ke kaula polyvinyl chloride.

Me ka nui o ka silicone i loko o ke ʻano, ʻaʻole wale ka hoʻoili ʻana e like me ka hoʻomaikaʻi ʻana i ka flowability akā loaʻa nō hoʻi kahi ʻoi aku ka maikaʻi o ka lapalapa ahi no ka mea.
