Ko te Sepiolite he momo kohuke he āhua muka, he hanganga muka e toro atu ana i te pakitara o ngā pūwero maha me te awa o ngā pūwero. Kei roto i te hanganga muka he hanganga paparanga, e titoa ana e ngā paparanga e rua o te hononga Si-O-Si he tetrahedron he silicon oxide, me te octahedron he konupora waikura kei waenganui, e hanga ana i te 0.36 nm × 1.06nm te whānui o te pūwero honikoma. Ko te tono ahumahi Sepiolite e hiahiatia ana.mira huri sepiolite paura hei huri hei paura sepiolite. He kaihanga ngaio a HCMilling (Guilin Hongcheng) o mira huri sepioliteKo te huinga taputapu katoa o ā mātou mira huri sepiolite Kua whānuitia te whakamahi i te raina whakaputa i te mākete. Nau mai ki te ako atu i runga ipurangi. Koinei te kupu whakataki ki te whakamahinga o te paura sepiolite:

1. Ngā āhuatanga o te sepiolite

(1) Ngā āhuatanga mimiti o te sepiolite

He hanganga motuhake toru-ahu te Sepiolite me te horahanga mata motuhake nui me te porosity paparanga, e honoa ana e te tetrahedron SiO2 me te octahedron Mg-O. He maha hoki ngā pokapū waikawa [SiO4] kawakore [MgO6] i runga i tōna mata, nō reira he kaha te mahi adsorption a te sepiolite.

E toru ngā wāhi pokapū hohe o te hanganga tioata Sepiolite:

Ko te tuatahi ko te ngota O i roto i te tetrahedron Si-O;

Ko te tuarua ko ngā ngota wai e mahi tahi ana me te Mg2+ i te taha o te octahedron Mg-O, e hanga ana i ngā hononga hauwai me ētahi atu matū;

Ko te tuatoru ko te hononga hononga Si OH, ka puta mai i te whatinga o te hononga hāora silicon i roto i te tetrahedron SiO2, ā, ka whiwhi i te porotona, i te ngota warowaihā rānei hei whakakapi i te pūmanawa ngaro. Ka taea e te hononga Si OH i roto i te sepiolite te taunekeneke me ngā ngota i piri ki tōna mata hei whakapakari i te piri, ā, ka taea te hanga hononga honohono me ētahi matū rauropi.

(2) Te pumau wera o te sepiolite

He uku kore-waro te Sepiolite, he ātete pumau ki te pāmahana teitei. I roto i te tukanga whakamahana āta haere mai i te pāmahana iti ki te pāmahana teitei, e whā ngā wāhanga whakaheke taumaha kua pā ki te hanganga tioata o te sepiolite:

Ina tae te pāmahana o waho ki te 100 ℃, ko ngā ngota wai ka ngaro i te sepiolite i te wāhanga tuatahi ko te wai zeolite i roto i ngā pūwero, ā, ko te ngaronga o tēnei wāhanga o ngā ngota wai ka eke ki te 11% o te taumaha katoa o te sepiolite.

Ina tae te pāmahana o waho ki te 130 ℃ ki te 300 ℃, ka ngaro i te sepiolite i te wāhanga tuarua te wāhanga tuatahi o te wai honohono me te Mg2+, arā, tata ki te 3% o tōna taumaha.

Ina tae te pāmahana o waho ki te 300 ℃ ki te 500 ℃, ka ngaro i te sepiolite i te wāhanga tuatoru te wāhanga tuarua o te wai honohono me te Mg2+.

Ina eke te pāmahana o waho ki runga ake i te 500 ℃, ka ngaro te wai hanganga (- OH) e honoa ana ki te octahedron i roto i te wāhanga tuawhā. Kua tino whakangaromia te hanganga muka o te sepiolite i tēnei wāhanga, nō reira kāore e taea te whakakore i te tukanga.

(3) Te ātete ki te waikura o te sepiolite

He pai te ātete o te sepiolite ki te waikawa me te kawakore. Ina kei roto i te wairewa me te uara pH <3, >10 rānei, ka waikura te hanganga o roto o te sepiolite. Ina kei waenganui i te 3-10, ka whakaatu te sepiolite i te pumau kaha. E whakaatu ana tēnei he kaha te ātete o te sepiolite ki te waikawa me te kawakore, he take nui tēnei e whakamahia ai te sepiolite hei matua kore-waro hei whakarite i te tae kikorangi rite ki a Maya.

(4) Ngā āhuatanga whakatere o te sepiolite

He kawe whakakorikori iti te utu, ā, he tino whai hua te Sepiolite. Ko te take matua he nui ake te horahanga mata motuhake o te sepiolite me tōna ake hanganga paparanga porous i muri i te whakarerekētanga waikawa, he āhuatanga pai ēnei mō te whakamahinga o te sepiolite hei kawe whakakorikori. Ka taea te whakamahi i te Sepiolite hei kawe hei hanga i tētahi whakakorikori whakaahua me te mahi whakakorikori tino pai me te TiO2, e whakamahia whānuitia ana i roto i te hauwai, te waikura, te denitrification, te desulfurization, me ētahi atu.

(5) Te whakawhiti katote o te sepiolite

Ka whakamahia e te tikanga whakawhiti katote ētahi atu katote whakarewa he kaha ake te pōraira hei whakakapi i te Mg2+ i te pito o te octahedron i roto i te hanganga sepiolite, ā, ka huri i tōna mokowā paparanga me te waikawa o te mata, ka whakarei ake i te mahi mimiti o te sepiolite. Ko ngā katote konupora te nuinga o ngā katote whakarewa o te sepiolite, me te iti o ngā katote konumohe me te iti o ētahi atu katote. Mā te hanganga me te hanganga motuhake o te sepiolite ka ngāwari te whakawhiti a ngā katote i roto i tōna hanganga me ētahi atu katote.

(6) Ngā āhuatanga rheological o te sepiolite

He angiangi te āhua o te Sepiolite, engari ko te nuinga o ēnei he puranga hei paihere me te raupapa koretake. Ina whakarewaina te sepiolite ki te wai, ki ētahi atu whakarewa porotaka rānei, ka tere te marara o ēnei paihere, ka hanumi koretake hei hanga i tētahi whatunga muka matatini me te pupuri whakarewa koretake. Ka hangaia e ēnei whatunga he whakatārewatanga me te rheology kaha me te matotoru teitei, e whakaatu ana i ngā āhuatanga rheological ahurei o te sepiolite.

Hei tāpiritanga, kei te sepiolite anō hoki ngā āhuatanga o te whakamarumaru, te tango tae, te ātete mura me te whānui, he mea nui tēnei mō te whakamahinga i roto i te ao ahumahi.

2. Ngā Whakamahinga Matua o te Sepiolitetukanga paura eSepiolitemira huri

I te tere o te whanaketanga o te ōhanga o Haina, kei te piki haere te hiahia o te mākete mō ngā rauemi e pai ana ki te taiao, he nui te uara tāpiri. He momo rauemi kore-waro te Sepiolite, he pai te pumau nā tōna hanganga tioata motuhake, he kore parahanga, he pai ki te taiao, ā, he iti te utu. I muri i te tukatuka mā te mīhini huri sepiolite, ka taea te whakamahi whānui i roto i ngā momo mara ahumahi, pērā i te hoahoanga, te hangarau uku, te whakarite whakakorikori, te hanga tae, te whakamahine hinu, te tiaki taiao, te kirihou, me ētahi atu, he pānga nui tēnei ki te whanaketanga ahumahi o Haina. I taua wā anō, kua tīmata te iwi ki te aro nui atu ki te tono auaha me te whanaketanga hangarau o te sepiolite, me te whakateretere i te hanganga o tētahi mekameka ahumahi sepiolite matatau hei whakaoti i te korenga o te sepiolite i te mākete. He iti te uara tāpiri o ngā hua.
