Pehea e hoʻomaikaʻi ai i ka hoʻopuehu ʻana o nā mea pale ahi

Me ka hoʻohana ākea o nā mea polymer a me nā huahana mea kūʻai uila i ke ola o kēlā me kēia lā, ke piʻi nei ka nui o ke ahi, a ʻoi aku ka weliweli o ka pōʻino. Ua ʻoi aku ka nui o ka hana ʻana o ka flame retardant o nā mea polymer, i mea e hoʻokō ai i nā koi retardant ahi o nā plastics a me nā huahana rubber, e hōʻemi i ka haumia o ka lepo i hoʻokumu ʻia e ka lapalapa ahi, ua komo mai ka masterbatch flame retardant, a ke pāʻani nei i kahi mea nui. a he kuleana nui i ka hana ʻana i nā huahana hope loa.

Hana ʻia ʻo Flame retardant masterbatch e like me ke kumu kūpono, ma o ka hui pū ʻana o ka flame retardant, lubricant dispersant a me ka mea lawe, ma o ka hoʻomaʻemaʻe ʻana, ka hui ʻana, ka like ʻole a me ka extrusion granulation. Ma kēia, he mea nui ka dispersant, e hoʻohui i kahi hapa o ka dispersant hiki ke lilo i mea maikaʻi loa e hoʻolaha i ka hoʻopuehu ʻana o ke ahi retardant, i maʻalahi ka hoʻopuehu ʻana i ke kaʻina hana, e pale i ka agglomeration o ke ahi retardant, ka ʻoi aku ka maikaʻi o ka hoʻopuehu ʻana, i mea e hoʻokani ai nā molekala e hoʻopaʻa i ke ahi i kahi hopena maikaʻi o ka lapalapa ahi, ma laila e hoʻomaikaʻi ai i ka maikaʻi o ka lapalapa ahi o ka plastic, nā huahana lāʻau, e ʻoki ʻia ke ahi i ka wā mua.

Eia nō naʻe, i ka hoʻomaʻamaʻa ʻana, ʻaʻole hiki i ka nui o nā plastics a me nā ʻāpana pāpaʻi i loaʻa nā ʻāpana pale ahi ke hana i kā lākou mau waiwai pale ahi ma muli o ka hoʻopuehu ʻole ʻia o ka lapalapa ahi i loko o ka mea i loko o ke ahi, e hopena i ke ahi nui a me nā poho koʻikoʻi.

I mea e hoʻoikaika ai i ka hoʻopuehu like ʻana o ka lapalapa ahi a i ʻole ka flame retardant masterbatch i ke kaʻina hana hoʻoheheʻe huahana, e hōʻemi i ka hiki ʻana o ka hoʻopuehu ʻole ʻia e ka hopena o ka lapalapa ahi ʻaʻole hiki ke hoʻokō maikaʻi ʻia, a me ka hoʻomaikaʻi ʻana i ka maikaʻi o nā huahana pale ahi, Ua hoʻomohala ʻo SILIKE i kahi mea hoʻohui silicone SILIMER hyperdispersant i hoʻololi ʻia.

ʻO SILIMER kahi ʻano siloxane i hoʻololi ʻia i ka copolymerized tri-block i haku ʻia me nā polysiloxanes, nā pūʻulu polar a me nā hui kaula kalapona lōʻihi. Hiki i nā ʻāpana kaulahao polysiloxane ke pāʻani i kahi hana kaʻawale ma waena o nā molekele pale ahi ma lalo o ka ʻoki mīkini, e pale ana i ka hoʻohui ʻana o nā molekole pale ahi; ʻO nā ʻāpana kaulahao polar pūʻulu i loaʻa kekahi mau mea paʻa me ka lapalapa ahi, e pāʻani ana i ke ʻano o ka hui ʻana; ʻO nā ʻāpana kaula kalapona lōʻihi he kūpono maikaʻi loa me ka mea kumu.

He kūpono kēia ʻano huahana no nā resins thermoplastic maʻamau, TPE, TPU a me nā elastomers thermoplastic ʻē aʻe, a hiki ke hoʻomaikaʻi i ka hoʻohālikelike ʻana ma waena o nā pigments / filler powders / pauku hana a me nā ʻōnaehana resin, a mālama i ke kūlana dispersion o nā pauka paʻa.

I ka manawa like, hiki iā ia ke hōʻemi i ka viscosity o ka heheʻe, hoʻemi i ka torque o ka extruder, extrusion pressure, hoʻomaikaʻi i ka hana hana o ka mea, me ka lubrication hoʻoponopono maikaʻi, a i ka manawa like hiki ke hoʻomaikaʻi maikaʻi i ka manaʻo o ka ʻO ka ʻili o ka mea, me kahi pae o ka maʻalahi a ʻaʻole pili i nā waiwai mechanical o ka mea, ʻo ia ka mea e hāpai i ka hoʻopuehu like ʻana o nā ʻāpana pale ahi e hoʻoikaika i ka hopena ahi o ka huahana hope e hāʻawi i ka pāʻani piha i ka kiʻekiʻe. -nā hoʻonā maikaʻi.

Eia kekahi, ʻaʻole kūpono kēia ʻano huahana no ka masterbatch retardant flame, akā no ka masterbatch kala a i ʻole nā ​​mea i hoʻopuehu mua ʻia.
