Kusanthula kwa njira zitatu zopangira alumina hydroxide yopangira

Makampani a aluminiyamu hydroxide amadziwika kuti alumina hydrate, chifukwa cha kuyera kwake kwabwino, chiŵerengero cha refractive chimachepetsa, chosavuta kuchikonza, chokhala ndi mphamvu yabwino yoletsa moto, komanso ntchito yoletsa utsi, kotero kuti aluminiyamu hydroxide ndi yabwino kwambiri yopangira miyala yodzaza.

Zinthu zopangidwa ndi miyala yopangidwa ndi aluminiyamu hydroxide zili ndi makhalidwe awa:

Kulemera kopepuka, mtengo wotsika, kosavuta kukonza, mtundu wabwino, kulimba bwino, kulumikiza kosalala kumatha kuchitika, ndipo njira yake yopangira ndi yosavuta, nthawi yochepa yopangira. Chifukwa chake, idafalikira mwachangu kumadera onse a dziko lapansi, yomwe imadziwika kuti ndi mtundu wa zipangizo zomangira zomwe zimagwiritsidwa ntchito kwambiri.

Pakadali pano, kufunika kwa aluminiyamu hydroxide padziko lonse lapansi pachaka kwa miyala yopangira ndi pafupifupi matani 700,000, ndipo kukula kwa pachaka kuli pafupifupi 10%. Ziwerengero zosakwanira, kufunikira kwa msika wa miyala yopangira ku China pachaka pa 1100 sikweya mita, ndipo mphamvu yopangira ya opanga miyala yopangira pano ndi 7 miliyoni sikweya mita, kuthekera kwa msika ndi kwakukulu.

Chifukwa cha njira yapadera yoyeretsera ndi njira yozama yoyeretsera ya sodium chlorate popanga alumina pogwiritsa ntchito njira yoyeretsera laimu, zinthu zopangidwa ndi aluminiyamu hydroxide zomwe zimapangidwa zimakhala ndi mawonekedwe oyera kwambiri komanso otsika achitsulo, ndipo zili ndi zabwino zapadera. Kutengera kukula kwachangu kwa makampani opanga miyala, mzere wopanga wa aluminiyamu hydroxide filler ukukulitsidwa mwachangu kuti ukulitse gawo la msika kunyumba ndi kunja.

Otsatirawa ndi opanga aluminiyamu hydroxide ya miyala yopangira popanga aluminiyamu hydroxide. Njira zitatuzi zikuyambitsidwa motere:

(1) zinthu zomwe zimapangidwa ndi kulekanitsa kaboni zimakhala ndi kuyera pang'ono, pH yapamwamba komanso SiO2% yapamwamba, komanso kuyera kochepa. Njira yopangira kaboni, kukula kwa tirigu woyambirira wa chinthucho ndi kochepa, pamwamba pa tirigu ndi kolimba kwambiri, kristalo wa kristalo ndi womasuka kwambiri, mulingo wa kristalo ndi wochepa, porosity ndi yayikulu, izi ndizomwe kuchuluka kwa mafuta omwe amayamwa ndi okwera, ndipo kupanga kwake kuyera kwa mbale yamwala yopangidwa ndi miyala ndi kwakukulu.

(2) zinthu zomwe zimapangidwa pogwiritsa ntchito njira yogawa zimakhala ndi kuyera kochepa, kuchuluka kwa kuyamwa kwa mafuta, pH yotsika, SiO2% yotsika ya zinthuzo komanso kuyera kwambiri. Njira yogawanitsa mbewu imapanga zinthu, kukula kwa makristalo kumakhala kwangwiro, pamwamba pa tinthu ta kristalo ndi kowala komanso koyera, makristalo ndi okhuthala kwambiri, digiri ya kristalo ndi yabwino, kusiyana pakati pa tinthu tating'onoting'ono ndi kochepa, izi ndi kuchuluka kwa kuyamwa kwa mafuta a chinthucho ndi kochepa, ndi kupanga kwake mphamvu ya mbale yamwala yopangidwa.

(3) zinthu zopangidwa ndi njira yosakaniza zimakhala ndi kuyamwa mafuta kochepa kwambiri komanso kuyera kochepa kwambiri. Njira yosakaniza zinthu, tinthu tating'onoting'ono ta zinthu zopangira, ndi tinthu tating'onoting'ono ta carbon filler, gradation, kudzaza kwathunthu, kumapangitsa kuti aluminium hydroxide ipangidwe ndi kuchuluka kwa kuyamwa mafuta kuchepe kwambiri, nthawi yomweyo, kukhuthala kwa chinthucho kumakhala kochepa, kosakwana 20000 eps, ndi mtengo wake wotsika, kupanga mbale yamwala yopangira komanso makasitomala safunika kugawa aluminium hydroxide filler, kupatula Labour.
