Otinga

He rauemi matū kore-waro nui te pāriuma whanariki i tukatukahia mai i te konganuku mata barite. Ehara i te mea he pai te mahi whatu me te pumau matū anake, engari he āhuatanga motuhake anō hoki pērā i te rōrahi, te rahi matū me te pānga atanga. Nō reira, he whānuitia te whakamahinga i roto i ngā paninga, kirihou, pepa, rapa, waituhi me te tae me ētahi atu mara. He painga tō te pāriuma whanariki nanometer o te horahanga mata motuhake teitei, te kaha teitei, te marara pai, me ētahi atu. Ka taea e ia te whakaatu i te mahi tino pai ina whakamahia ki ngā rauemi hiato. He kaihanga ngaio a HCMilling (Guilin Hongcheng) obaritemira huringā mīhini. Ā mātoubariteroera poutūmira Ka taea e te mīhini te huri i te paura barite 80-3000 mesh. E whai ake nei he kupu whakataki ki ngā mara tono o te nano barium sulfate.

1. Ahumahi kirihou — i muri i te tukatuka me baritemira hurimīhini

Kua nui haere te aro ki te tāpiri i te nano barium sulfate i tukatukahia e te mīhini huri barite ki te polymer hei whiwhi i ngā rauemi hiato he kaha, he pakari hoki. Hei tauira, ka taea te tāpiri i te barium sulfate ki te polyethylene (PE), te polypropylene (PP), te waikawa polylactic (PLA), te polytetrafluoroethylene (PTFE) me ētahi atu rauemi. Ina koa, kua tino pai ake ngā āhuatanga miihini o te barium sulfate i muri i te whakarerekētanga o te mata.

Mō te nuinga o ngā rauemi whakakotahi pūmua, me te pikinga ake o te nui o te whakarerekētanga, ka piki ake te kaha me te pakari o ngā rauemi whakakotahi i te tuatahi, kātahi ka heke iho. Nā te mea ko te nui rawa o te whakarerekētanga ka arahi ki te mimiti ā-tinana maha-paparanga ki runga i te mata o te nano barium sulfate, ka puta he huihuinga nui i roto i te pūmua, ka pā ki ngā āhuatanga hangarau o ngā rauemi whakakotahi, ā, ka uaua ki te whakamahi i ngā āhuatanga pai o ngā whakakī kore-waro; Mā te iti o te whakarerekētanga ka whakanui ake i ngā hapa atanga i waenga i te nano barium sulfate me te pūmua, ka hua ake he hekenga o ngā āhuatanga hangarau o te whakakotahi.

Haunga te nui o te whakarerekētanga mata i runga ake nei he pānga nui ki ngā āhuatanga ā-pūkaha o te rauemi whakakotahi, he mea nui anō hoki te nui o te barium sulfate. Nā te mea he tino nui te kaha o te nano barium sulfate, ka taea e ia te whai wāhi ki te pupuri i te hononga ina tāpirihia ki te rauemi whakakotahi, ā, ka puta he pānga whakapakari. Heoi, ina nui rawa te ihirangi o te nano barium sulfate (neke atu i te 4%), nā te mea ka kohikohi i roto i te rauemi whakakotahi me te tāpiri o ngā matūriki kore-waro, ka piki ake ngā hapa o te matrix, ka ngawari ake te pakaru o te rauemi whakakotahi, ā, ka kino ake ngā āhuatanga ā-pūkaha o te rauemi whakakotahi. Nō reira, me noho te nui o te barium sulfate tāpiri ki roto i ōna āhuatanga ā-pūkaha e tika ana.

2. Te umanga paninga — i muri i te tukatuka mebaritemira hurimīhini

Hei momo tae, he whānui te whakamahinga o te konupūmā pāriuma i roto i ngā paninga, ā, he mea nui ki te whakapai ake i te matotoru, te ātete ki te pakū, te ātete ki te wai, te ātete ki te wera, te pakeke o te mata me te ātete ki te pānga o ngā paninga. Hei tāpiri, nā te iti o te mimiti hinu me te kaha whakakī nui, ka taea te whakamahi i roto i ngā paninga wai-pūtake, ngā paninga tuatahi, ngā paninga waenga me ngā paninga hinuhinu hei whakaiti i te utu o ngā paninga. Ka taea e ia te whakakapi i te 10% ~ 25% o te hauhā titanium i roto i ngā paninga wai-pūtake. E whakaatu ana ngā hua kua pai ake te mā, ā, kāore i whakaitihia te kaha huna.

Ko ngā āhuatanga o te konupūmā barium tino pai mō ngā paninga ko: 1) he tino pai te rahi o te matūriki, ā, he whāiti te tohatoha o te rahi o te matūriki; 2) He mārama ina whakamararatia ki roto i te otinga kapia; 3) He pai te whakamararatanga i roto i te rauemi turanga paninga; 4) Ka taea te whakamahi hei kaihoko whakamarara me te tae waro; 5) Ka taea te whakapai ake i ngā āhuatanga ā-tinana.

3. Ahumahi pepa — i muri i te tukatuka e bariteroera poutūmira mīhini

E whakamahia ana te pārium sulfate i roto i te umanga hanga pepa nā te mea he pai tōna pumau ā-tinana, ā-matū hoki, he pakeke taurite, he mā te tae, ā, he mimiti hoki i ngā hihi kino.

Hei tauira, he mea noa te pepa waro hei taputapu ako me ngā taputapu tari, engari he ngāwari te tango i te tae o tōna mata, nō reira me nui te kaha mimiti hinu o te barium sulfate, ka pai ake te mimiti waituhi o te pepa; he iti, he ōrite te rahi o te matūriki, ka papatahi ake te pepa, ka iti ake te mau o te mīhini.

4. Te umanga muka matū — i muri i te tukatuka mā bariteroera poutūmira mīhini

Ko te muka viscose, e mōhiotia ana ko te "miro horihori", he rite ki te muka miro tūturu i roto i te taiao, pērā i te ārai-pūmau, te mimiti pai o te makuku, te ngāwari ki te tae, me te ngāwari ki te tukatuka kakahu. He pai te pānga nano o te nano barium sulfate. Ko te muka whakaranu nano barium sulfate/cellulose i hangaia mai i ngā mea e rua hei rauemi mata he momo muka hiato hou, ka taea te pupuri i ngā āhuatanga ahurei o ia wāhanga. Heoi anō, mā te "mahi tahi" i waenganui i a rāua, ka taea te whakakī i ngā ngoikoretanga o te rauemi kotahi me te whakaatu i ngā āhuatanga hou o ngā rauemi hiato.
