Aluminiyamu hydroxide ofukula mphero

Aluminium hydroxide ndi mankhwala omwe amagwiritsidwa ntchito kwambiri, amakhala okhazikika bwino pa mankhwala, samayambitsa poizoni, alibe kukoma, akhala chinthu chofunikira kwambiri pakupanga magetsi, zamagetsi, mapepala, mankhwala ndi mafakitale ena. Chifukwa cha kukonzedwa bwino kwa aluminiyamu hydroxide, kapangidwe ka zamagetsi pamwamba ndi kapangidwe ka kristalo kamasintha, zomwe zimapangitsa kuti pamwamba pake pakhale mphamvu ndi kukula kwake, kotero kuti imakhala ndi mphamvu zapadera pakugwira ntchito kwa mankhwala, magwiridwe antchito amagetsi, mawonekedwe apamwamba ndi zina, ndipo ili ndi ntchito zambiri zapadera. Ufa wa aluminiyamu hydroxide wopangidwa ndi mphero yoyimirira ya aluminiyamu hydroxide si chinthu chogwira ntchito chokha, komanso umapereka mwayi wogwiritsidwa ntchito kwambiri pakupanga zipangizo zatsopano, ndipo umagwira ntchito yofunika kwambiri m'magawo osiyanasiyana azachuma cha dziko.Guilin HongchengMonga opanga mipiringidzo yoyimirira ya aluminiyamu hydroxide, lero kuti muyambe kugwiritsa ntchito msika waukulu wa aluminiyamu hydroxide.

Msika waukulu wa aluminiyamu hydroxide:

1. Makampani oletsa kuyaka: aluminiyamu hydroxide ili ndi kuuma pang'ono, mphamvu zokhazikika zakuthupi ndi zamakemikolo kutentha kwa chipinda, si poizoni, komanso mtengo wotsika wopanga. Aluminiyamu hydroxide imatenthedwa kufika pa 220C ndipo inayamba kutentha kuyaka, kutulutsa madzi ophatikizana. Chifukwa njira iyi yochotsera madzi m'thupi imachedwetsa kuyaka kwa polima ndikuchepetsa liwiro la kuyaka. Imachokera pakuwola kwa kutentha kwakukulu, ndipo imangotulutsa nthunzi yamadzi mu kuwola kwa kutentha, ndipo sipanga mpweya woopsa, woyaka kapena wowononga, aluminiyamu hydroxide yakhala chinthu chofunikira chodzaza moto chosapangidwa ndi zinthu zachilengedwe.

2. Chodzaza ndi chowonjezera cha guluu ndi chotseka: Chodzaza cha aluminiyamu hydroxide chingathandize kukonza magwiridwe antchito, mphamvu, kuyendetsa bwino kutentha komanso kukula kwa mphamvu ya guluu ndi chotseka, ndipo chingachepetse kuchuluka kwa guluu ndikuchepetsa mtengo wa chinthucho. Kugwiritsa ntchito ma binder ku Europe ndi US kukukulirakulira ndi pafupifupi 5% pachaka, ndipo kufunikira kwa zotseka kukukulirakulira ndi 1% ku Europe.

3. Kupaka mapepala: aluminiyamu hydroxide mumakampani opanga mapepala, makamaka amagwiritsidwa ntchito ngati zokutira pamwamba, zodzaza ndi kupanga mapepala osayaka. Kale m'ma 1940 ndi 1950, aluminiyamu hydroxide inayamba kupangidwa ndikugwiritsidwa ntchito ngati utoto wokutira, ndipo yapanga sikelo yokhazikika yopanga, yomwe imagwiritsidwa ntchito kwambiri popanga mapepala okhala ndi makatoni, pepala la kaboni. Ku China, kugwiritsa ntchito aluminiyamu hydroxide mumakampani opanga mapepala ndikochepa, ndi chitukuko ndi kupanga kwa aluminium hydroxide ya ultrafine, kugwiritsa ntchito aluminiyamu hydroxide mumakampani opanga mapepala kudzapitirira kukula. Aluminiyamu hydroxide, monga mtundu watsopano wa utoto wokutira, poyerekeza ndi utoto wachikhalidwe, ili ndi zabwino zambiri: kuyera kwambiri, kukula kwa tirigu wabwino, mawonekedwe abwino a kristalo, magwiridwe antchito abwino ndi choyeretsera, kuyamwa bwino kwa inki. Kugwiritsa ntchito ngati utoto, kumatha kusintha kuyera, kuonekera bwino, kusalala, kuyamwa kwa inki kwa pepala lokutidwa, kungagwiritsidwe ntchito popanga mapepala opaka utoto, pepala lojambula zithunzi ndi pepala lotanthauzira mawu lapamwamba ndi mapepala ena apamwamba.

4. Chothandizira kukangana kwa phula la mano: aluminiyamu hydroxide si poizoni komanso yopanda kukoma, Mohs hardness 2.5-3.5, yofewa komanso yolimba pang'ono, ndi chothandizira kukangana bwino, aluminiyamu hydroxide m'malo mwa zosakaniza zachikhalidwe za choko ndi dicalcium phosphate ikhoza kupangidwa kukhala mankhwala otsukira mano okhala ndi magwiridwe antchito abwino. Kusagwira ntchito kwa phula la aluminium hydroxide kumapangitsa kuti ligwirizane ndi zosakaniza zina mu mankhwala otsukira mano; pakadali pano, imagwiritsidwa ntchito kwambiri mu mankhwala otsukira mano ndi mankhwala ena otsukira mano apamwamba.

5. Mankhwala ndi zina: Aluminium hydroxide ndi chimodzi mwa zigawo zazikulu za mankhwala am'mimba. Aluminium gel ndi mankhwala achikhalidwe ochepetsa asidi m'mimba ndikuchiza mavuto am'mimba. Aluminium chloride yopangidwa kuchokera ku aluminum hydroxide ngati zinthu zopangira ingagwiritsidwe ntchito ngati condensant mu mankhwala ndi zodzoladzola. Kuphatikiza apo, aluminum hydroxide ndi aluminiyamu oxide yake yophikidwa mwapadera yagwiritsidwa ntchito kwambiri mu mankhwala a mankhwala, ma catalysts, mapulasitiki, zokutira, ziwiya zadothi, zinthu zotsutsana ndi mpweya, zinthu zotetezera kutentha, zinthu zopukutira mpweya ndi zina.
