Te Whakamahinga o te Hauwai Konumohe

Ko te "alumina matū" e pā ana ki te hanga o te ingota konumohe engari ko te alumina, te waikura konumohe me te hauwai konumohe kua rerekētia, ngā hua whānuitia rānei. He rau ngā momo alumina matū, ā, he whānuitia ngā whakamahinga i roto i ngā mara rerekē. Ka whakamāramahia e tēnei tuhinga ngā whakamahinga e pā ana ki te hauwai konumohe.

Ko te hauwai konumohe, e mōhiotia ana ko te alumina waikura, te alumina hauwai, te hauwai alumina, he matū amphoteric noa iho, he wairewa i roto i ngā waikawa me ngā turanga, kāore e wairewa i roto i te wai me te waipiro. Ko te tātai whānui ko Al2O3 • H2O me te ira rewa o te 300 (te ngaronga o te wai). E ai ki te nui o te wai, ka taea te wehewehe i te raupapa hauwai konumohe ki: te alumina trihydrate, te alumina monohydrate, te alumina iti te tioata me te hauwai konumohe amorphous. I tangohia mai i te bauxite, ka taea hoki te hanga mai i te tote konumohe me te hauwai konutai me te wai haukini. E rua ngā momo tioata me te amorphous (kiri).

He iti te kawakore o te hauwai konumohe koretake, he iti te rino, he pai ngā matūriki, ā, he mā te tae. He pai ngā painga o te tauira whaipainga, arā, he pakeke rawa, he ātete ki te wera, he ātete ki te kakahu, he pumau matū pai, kāore e paitini, kāore he reka, kāore e memeha, he maroke, he mimiti wera ina werahia ki runga ake i te 250 DEG C, ā, he pai te whakakore paowa me te ātete ki te mura. Ko ngā wāhi tono matua koia ēnei.

Ko te hauwai konumohe he momo whakakī parakore kore-parakore, he iti te ihirangi poke, ā, ko ngā momo pūmua e whakamahi ana i te hauwai konumohe hei whakakī ko te kapia polyurethane, te kapia epoxy, te polyethylene, te polypropylene, te rapa styrene butadiene, me ētahi atu. Ko te hauwai konumohe hei ārai mura me te pehi paowa kua whakamahia i roto i te kapia kore-mākū mō ngā tau maha.

Ko te tikanga ārai mura mō te tāpiri i te ATH ki te pūmua, hei whakaiti i te kukū wahie; ka tīmata te hauwai konumohe i te 250 DEG C te maroketanga endothermic, ka aukati i te pikinga o te pāmahana pūmua; ka memeha te kohu wai i te kukū hāora, ka puhoi te mura; i te whakaputa i te mata mura o te alumina ka taea te aukati i te haere tonu o te tauhohenga mura.

Ko te hauwai konumohe e whakamahia nuitia ana i roto i te umanga paninga mō ngā paninga mata, ngā whakakī, me te pepa kore e mura. Ka taea e te hauwai konumohe te whakapai ake i te kanapa, te whakaata, te ātete ki te mārama, te maeneene me te āheinga tā o te pepa. Ka taea hoki te whakamahi i te hauwai konumohe hei rauemi mata mō te pepa pania, ā, ka whakakapia te uku e te titania. Ko te rahi o te matūriki hauwai konumohe e whakamahia whānuitia ana ko te 0.7-1.4 mu m.

Pepa ārai ahi: ārai mura, whakawaro ahi, engari kāore e mura. He mea hanga ki te pepa asbestos, he pepa ārai mura rānei kua pania ki te pepa e tika ana (pērā i te konumohe hauwai) me te rongoā.

Kāore te hauwai konumohe i te paitini, kāore hoki he reka, kāore e rewa i te wai, he momo pai mō te waku koretake. Ko te hauwai konumohe i hangaia i roto i te ahumahi, ko te pakeke o te hauwai konumohe he 2.5-3.5, ko te parakore neke atu i te 99%, ko te pH he 8.0-9.5, ko te D50 he 8-15 micron, he utu taurite, he pai mō te waku o te paraihe niho, he hototahi ki te fluoride, he pai te mahi. Ko tētahi o ngā rongoā pai rawa atu mō te whakakoi paraihe niho.

Ko te Mullite (mullite rānei) he raupapa kohuke he mea tito mai i te aluminosilicate. Ko te Mullite anake te matū pūmau e rua ngā huānga i roto i te pūnaha Al2O3 SiO2. He iti noa iho tēnei momo kohuke. He momo ātete kounga teitei, ā, ka taea te hanga i te mullite mā te whakamahana i te silicate konumohe mā te hanga. Ko te nuinga o te whakamahinga o te Mullite i roto i ngā ātete, ngā uku, te whakarewa, te whakarewa, te hikohiko me ētahi atu ahumahi. He āhuatanga ōna o te ātete pāmahana teitei, te kaha teitei me te iti o te kawe wera.

Hei tāpiritanga, ka taea te whakamahi i te hauwai konumohe hei māpere horihori, hei ākete horihori, hei whakakī whāriki; hei hanga i te konumohe whanariki, te konumohe, te alumina, te alumina waikura, te konutai aluminate rauemi matū, hei hanga hua rapa; hei aukati mura; hei whakakī me te tāpiri i ngā piripiri me ngā hiri; hei tātari ngota hangai; hei rongoā waikawa puku, me ētahi atu.

Ko ngā momo konumohe waikura konumohe he konumohe waikura, he boehmite, he alumina amorphous. He pai te piri, te hanga, he ātete ki te pāmahana teitei, he nui te kaha wera, he iti te kawe wera, he pai te ātete ki te waikura me te waikura, he kaha teitei, ā, he maeneene te mata.

Ko te hauwai konumohe tētahi o ngā wāhanga matua o te hinu konumohe puku hei rongoā i te waikawa puku me te waikawa puku, rongoā tuku iho, ngā whakaritenga matū pēnei i te huaora U me ngā kāpū konumohe, ngā papa hauwai konumohe me ētahi atu wāhanga nui, ka taea hoki te whakamahi hei rauemi rongoā. Ko te tikanga o tana waikawa ārai puku ko Al (OH)3+6HCl=2AlCl3+3H2O. E ono ngā alumina wai i hangaia mai i te hauwai konumohe ka taea te whakamahi hei whakapūkara i roto i te mara o te rongoā me te whakapaipai.

Te maimoatanga mata me te piripiri piripiri Ka taea te whakamahi i te Aluminium Hydroxide Gel ki te muka kore-waro, ki te muka waro rānei, mā te whakamahi i tōna ātete pāmahana teitei me te whakaotinga mata, e whakamahia whānuitia ana i roto i te hanga taputapu uku kounga teitei, e whakamahia ana hoki mō te hanga porcelain hiko; i te wa ano he whakakī kore-waro.
