He mea nui ka Barium sulfate i nā kemika inorganic i hana ʻia mai ka barite raw ore. ʻAʻole wale ia he hana optical maikaʻi a me ke kūpaʻa kemika, akā he mau ʻano kūikawā hoʻi e like me ka nui, ka nui quantum a me ka hopena interface. No laila, hoʻohana nui ʻia ia i nā uhi, nā plastics, ka pepa, ka rubber, ka ʻīnika a me ka pigment a me nā ʻoihana ʻē aʻe. Loaʻa i ka nanometer barium sulfate nā pono o ka ʻili kikoʻī kiʻekiʻe, ka hana kiʻekiʻe, ka hoʻopuehu maikaʻi, a pēlā aku. Hiki iā ia ke hōʻike i ka hana maikaʻi loa ke hoʻopili ʻia i nā mea composite. ʻO HCMilling (Guilin Hongcheng) kahi mea hana loea obaritewili wilinā mīkini. ʻO kā mākoubaritewili kū pololeiwili hiki i ka mīkini ke wili i ka pauka barite 80-3000 mesh. Eia ka hoʻolauna ʻana i nā kahua noi o ka nano barium sulfate.

1. ʻOihana palakiko — ma hope o ka hana ʻana me baritewili wilimīkini

ʻO ka hoʻohui ʻana i ka nano barium sulfate i hana ʻia e ka mīkini wili barite i ka polymer e loaʻa ai nā mea composite me ka ikaika a me ka paʻakikī ua huki nui ʻia ka nānā. 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. ʻOi loa aku, ua hoʻomaikaʻi nui ʻia nā waiwai mechanical o ka barium sulfate ma hope o ka hoʻololi ʻana i ka ʻili.

No ka hapa nui o nā hui polymer, me ka hoʻonui ʻia o ka nui o ka mea hoʻololi, e hoʻonui mua ka ikaika a me ka paʻakikī o nā mea hui a laila e emi iho. ʻO kēia no ka mea ʻo ka nui o ka mea hoʻololi e alakaʻi i ka adsorption kino multi-layer ma luna o ka ʻili o ka nano barium sulfate, e hana ana i ka agglomeration koʻikoʻi i loko o ka polymer, e hoʻopilikia ana i nā waiwai mechanical o nā mea hui, a e paʻakikī ai ke pāʻani i nā ʻano maikaʻi loa o nā mea hoʻopihapiha inorganic; 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 ana i ka emi ʻana o nā waiwai mechanical o ka hui.

Ma waho aʻe o ka nui o ka mea hoʻololi ʻili i luna nei he hopena nui ia i nā waiwai mechanical o ka composite, ʻo ka nui o ka barium sulfate he mea nui hoʻi. ʻO kēia no ka mea he nui loa ka ikaika o ka nano barium sulfate, hiki ke pāʻani i kahi kuleana i ka hali ʻana i ka wā e hoʻohui ʻia ai i ka composite, a laila e hana ana i kahi hopena hoʻoikaika. Eia naʻe, i ka wā e kiʻekiʻe loa ai ka nui o ka nano barium sulfate (ʻoi aku ma mua o 4%), ma muli o kona agglomeration i loko o ka composite a me ka hoʻohui ʻana o nā ʻāpana inorganic, hoʻonui ʻia nā hemahema matrix, ka mea e ʻoi aku ka maʻalahi o ka composite i ka haki ʻana, a laila e ʻoi aku ka ʻino o nā waiwai mechanical o ka composite. No laila, pono ka nui o ka hoʻohui ʻana o ka barium sulfate i loko o kona mau waiwai mechanical kūpono.

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

Ma ke ʻano he ʻano pigment, hoʻohana nui ʻia ka barium sulfate i nā uhi a he kuleana koʻikoʻi ia i ka hoʻomaikaʻi ʻana i ka mānoanoa, ke kūpaʻa ʻana i ka abrasion, ke kūpaʻa wai, ke kūpaʻa wela, ka paʻakikī o ka ʻili a me ke kūpaʻa hopena o nā uhi. Eia kekahi, ma muli o kona haʻahaʻa o ka omo ʻana o ka aila a me ka hiki ke hoʻopiha kiʻekiʻe, hiki ke hoʻohana ʻia i nā uhi wai, nā primers, nā uhi waena a me nā uhi ʻaila e hōʻemi i ke kumukūʻai o nā uhi. Hiki iā ia ke pani i ka 10% ~ 25% o ka titanium dioxide i nā uhi wai. Hōʻike nā hopena ua hoʻomaikaʻi ʻia ke keʻokeʻo a ʻaʻole i emi ka mana hūnā.

ʻO nā ʻano o ka barium sulfate superfine no nā uhi ʻana: 1) ka nui o nā ʻāpana liʻiliʻi loa a me ka hoʻolaha ʻana o ka nui o nā ʻāpana; 2) He moakāka ia i ka wā e hoʻopuehu ʻia ai i loko o ka hopena resin; 3) Hoʻopuehu maikaʻi ʻia i loko o ka mea kumu uhi; 4) Hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻopuehu 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 kū pololeiwili mīkini

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

No ka laʻana, he mea maʻamau ka pepa kalapona no ke aʻo ʻana a me nā lako keʻena, akā maʻalahi ka hoʻokaʻawale ʻana i kona ʻili, no laila pono ka barium sulfate e loaʻa kahi waiwai hoʻomoʻa aila kiʻekiʻe, hiki ke hoʻomaikaʻi i ka hoʻomoʻa ʻana o ka ʻīnika o ka pepa; He liʻiliʻi a like ka nui o nā ʻāpana, hiki ke hoʻonui i ka palahalaha o ka pepa a hoʻemi i ke kapa ʻana o ka mīkini.

4. ʻOihana fiber kemika — ma hope o ka hana ʻana e baritewili kū pololeiwili mīkini

ʻO ke olonā viscose, i ʻike ʻia hoʻi ʻo "artificial cotton", ua like ia me ke olonā pulupulu maoli ma ke ʻano, e like me ka anti-static, ka omo maikaʻi o ka makū, ka maʻalahi o ka hoʻoluʻu ʻana, a me ka hana maʻalahi o ka lole. Loaʻa i ka nano barium sulfate ka hopena nano maikaʻi. ʻO ka nano barium sulfate/regenerated cellulose blend fiber i hana ʻia mai nā mea ʻelua ma ke ʻano he mea maka he ʻano hou ia o ka fiber composite, hiki ke mālama i nā waiwai kūikawā o kēlā me kēia ʻāpana. Eia kekahi, ma o ka "synergy" ma waena o lākou, hiki iā ia ke hoʻopiha i nā hemahema o ka mea hoʻokahi a hōʻike i nā waiwai hou o nā mea composite.
