ʻO ka Barium sulfate kahi mea koʻikoʻi kemika inorganic i hana ʻia mai ka barite raw ore.ʻAʻole wale ia he hana optical maikaʻi a me ke kūpaʻa kemika, akā loaʻa pū kekahi mau hiʻohiʻona kūikawā e like me ka nui, ka nui quantum a me ka hopena interface.No laila, hoʻohana nui ʻia ia i nā uhi, plastics, pepa, rubber, inika a me ka puaʻa a me nā māla ʻē aʻe.ʻO ka Nanometer barium sulfate ka maikaʻi o ka ʻāpana kikoʻī kiʻekiʻe, ka hana kiʻekiʻe, ka hoʻopuehu maikaʻi, a me nā mea ʻē aʻe.ʻO HCMilling(Guilin Hongcheng) he mea hana ʻoihana obaritewili palaoanā mīkini.ʻO kā mākoubaritewili kūkaʻiwili hiki i ka mīkini ke wili 80-3000 mesh barite pauka.ʻO kēia ka hoʻolauna ʻana i nā kahua noi o ka nano barium sulfate.

1. ʻOihana palaki - ma hope o ka hana ʻana me baritewili palaoamīkini

ʻO ka hoʻohui ʻana i ka nano barium sulfate i hana ʻia e ka barite grinding machine i ka polymer no ka loaʻa ʻana o nā mea hana me ka ikaika kiʻekiʻe a me ka paʻakikī.No ka laʻana, hiki ke hoʻohui ʻia ka barium sulfate i ka polyethylene (PE), polypropylene (PP), polylactic acid (PLA), polytetrafluoroethylene (PTFE) a me nā mea ʻē aʻe.ʻO ka mea nui, ua hoʻomaikaʻi maikaʻi ʻia nā waiwai mechanical o ka barium sulfate ma hope o ka hoʻololi ʻana o ka ʻili.

No ka hapa nui o nā composites polymer, me ka hoʻonui ʻana i ka nui o ka mea hoʻololi, hoʻonui mua ka ikaika a me ka paʻakikī o nā mea hoʻohui a laila emi.ʻO kēia no ka mea ʻo ka nui o ka mea hoʻololi e alakaʻi i ka adsorption kino multi-layer ma ka ʻili o ka nano barium sulfate, e hoʻoulu ai i ka agglomeration koʻikoʻi i ka polymer, e hoʻopilikia ana i nā waiwai mechanical o nā mea hoʻohui, a paʻakikī ke pāʻani i nā hiʻohiʻona maikaʻi loa. nā mea hoʻopiha kino;ʻO kahi liʻiliʻi o ka mea hoʻololi e hoʻonui i nā hemahema interface ma waena o ka nano barium sulfate a me ka polymer, e hopena i ka emi ʻana o nā waiwai mechanical o ka composite.

Ma waho aʻe o ka nui o luna o ka hoʻololi o ka ʻili he hopena nui i nā ʻano mechanical o ka composite, ʻo ka nui o ka barium sulfate kekahi mea nui.ʻO kēia no ka mea nui loa ka ikaika o ka nano barium sulfate, hiki ke hoʻokani i ke kuleana i ka lawe ʻana i ka wā i hoʻohui ʻia i ka composite, no laila e hana i kekahi hopena hoʻoikaika.Eia nō naʻe, ke kiʻekiʻe loa ka maʻiʻo o ka nano barium sulfate (ʻoi aku ma mua o 4%), no ka mea o kāna agglomeration i loko o ka composite a me ka hoʻohui ʻana o nā ʻāpana inorganic, piʻi ka matrix defects, kahi e hoʻonui ai i ka composite i ka haʻihaʻi, pēlā e hana ai i ka ʻoi aku ka maikaʻi o nā waiwai mechanical o ka hui.No laila, pono ka nui o ka barium sulfate i loko o kona mau pono mechanical.

2. ʻOihana uhi - ma hope o ka hana ʻana mebaritewili palaoamīkini

E like me ke ʻano o ka puaʻa, hoʻohana nui ʻia ka barium sulfate i nā uhi a he hana koʻikoʻi i ka hoʻomaikaʻi ʻana i ka mānoanoa, ka pale ʻana i ka abrasion, ke kūpaʻa wai, ka pale wela, ka paʻakikī o ka ʻili a me ka hopena o ka pale ʻana o nā uhi.Eia kekahi, ma muli o ka haʻahaʻa haʻahaʻa o ka ʻaila a me ka nui o ka hoʻopiha piha ʻana, hiki ke hoʻohana ʻia i loko o ka wai wai, nā primers, nā ʻāpana waena a me nā ʻaila hinu e hoʻemi ai i ke kumukūʻai o ka uhi.Hiki iā ia ke hoʻololi i ka 10% ~ 25% o ka titanium dioxide i nā uhi wai.Hōʻike nā hopena i ka hoʻomaikaʻi ʻana i ke keʻokeʻo a ʻaʻole i emi ka mana huna.

ʻO nā hiʻohiʻona o ka superfine barium sulfate no ka uhi ʻana: 1) ka nui o ka nui o nā ʻāpana liʻiliʻi a me ka hāʻawi ʻana i ka nui o nā ʻāpana haiki;2) He akaka ia i ka wā i hoʻopuehu ʻia i loko o ka hopena resin;3) Ka dispersibility maikaʻi i ka uhi ʻana i nā mea kumu;4) Hiki ke hoʻohana ʻia e like me ka dispersing agent i hui pū ʻia me ka pigment organik;5) Hiki iā ia ke hoʻomaikaʻi i nā waiwai kino.

3. ʻOihana pepa - ma hope o ka hana ʻana e baritewili kūkaʻiwili mīkini

Hoʻohana pinepine ʻia ka Barium sulfate i ka ʻoihana hana pepa ma muli o kona kūpaʻa kino a me ke kemika, paʻakikī paʻakikī, keʻokeʻo nui, a me ka absorption o nā kukuna ʻino.

No ka laʻana, he mea aʻo maʻamau ka pepa kalapona a me nā lako keʻena, akā maʻalahi kona ʻili i ka decolor, no laila koi ʻia ka barium sulfate e loaʻa kahi waiwai hoʻoheheʻe ʻaila kiʻekiʻe, hiki ke hoʻomaikaʻi i ka absorption ink o ka pepa;He liʻiliʻi a ʻaʻahu like ka nui o ka ʻāpana, hiki ke hana i ka pepa i ʻoi aku ka palahalaha a hoʻemi i ka ʻaʻahu o ka mīkini.

4. ʻOihana fiber Chemical - ma hope o ka hana ʻana e baritewili kūkaʻiwili mīkini

ʻO ka fiber Viscose, ka mea i kapa ʻia ʻo "ka pulupulu artificial", ua like ia me ka pulupulu pulupulu maoli ma ke ʻano, e like me ka anti-static, maikaʻi ka hoʻoheheʻe ʻana i ka wai, maʻalahi ke kala, a me ka hana textile maʻalahi.ʻO ka nano barium sulfate he hopena nano maikaʻi.ʻO ka nano barium sulfate / regenerated cellulose blend fiber i hanaʻia mai nā meaʻelua e like me nā mea maka heʻano hou o ka fiber composite, hiki ke mālama i nā waiwai kūikawā o kēlā me kēia mea.Eia kekahi, ma o ka "synergy" ma waena o lākou, hiki iā ia ke hana i nā hemahema o ka mea hoʻokahi a hōʻike i nā waiwai hou o nā mea hoʻohui.
