Aluminum Sulfate
Hoʻolauna o Aluminum sulfate
ʻO ka Aluminum sulfate he paʻakai me ke ʻano Al2(SO4)3. Hiki ke hoʻoheheʻe ʻia i ka wai a hoʻohana nui ʻia ma ke ʻano he coagulating agent i ka hoʻomaʻemaʻe ʻana i ka wai inu a me nā mea kanu hoʻomaʻemaʻe wai, a me ka hana pepa. Loaʻa i kā mākou Aluminium Sulphate nā granules pauka, flakes, a me nā papa, hiki iā mākou ke hoʻolako i ka no-ferric, low-ferric, a me ka papa hana ʻoihana.
Aia ka Aluminum sulfate ma ke ʻano he keʻokeʻo, ʻulaʻula kristal, granules, a i ʻole ka pauka. Ma ke ʻano, aia ia ma ke ʻano he alunogenite mineral. ʻO ka alumini sulfate kekahi manawa i kapa ʻia ʻo alum a i ʻole alum a ka mea hana pepa.

Hoohana Hale
Loaʻa kekahi o nā mea maʻamau o ka alumini sulfate i loko o ka home. Loaʻa pinepine ʻia ka pūhui i ka soda baking, ʻoiai aia kekahi mau hoʻopaʻapaʻa no ka mea kūpono ke hoʻohui i ka alumini i ka meaʻai. Aia kekahi mau antiperspirants i ka alumini sulfate ma muli o kona mau waiwai antibacterial, ʻoiai i ka makahiki 2005 ʻaʻole ʻike ka FDA he mea hoʻemi wai. ʻO ka mea hope loa, ʻo ka hui ka mea astringent i loko o nā penikala styptic, i hoʻolālā ʻia e kāpae i nā ʻoki liʻiliʻi mai ke koko.
Mahiai
ʻO nā hoʻohana hoihoi ʻē aʻe o ka alumini sulfate a puni ka hale ma ka māla. Ma muli o ka ʻakika loa o ka alumini sulfate, hoʻohui ʻia i kekahi manawa i nā ʻāina alkaline e kaulike i ka pH o nā mea kanu. Ke hoʻopili ʻia ka alumini sulfate me ka wai, hana ia i ka alumini hydroxide a me kahi solution sulfuric acid i hoʻoheheʻe ʻia, e hoʻololi i ka ʻakika lepo. Hoʻohana ka poʻe māla e kanu i ka hydrangeas i kēia waiwai e hoʻololi i ka waihoʻoluʻu pua (uliuli a ʻulaʻula) o nā hydrangeas no ka mea ua maʻalahi kēia mea kanu i ka pH lepo.
Aluminum SulfateWater Laau
ʻO kekahi o ka hoʻohana nui ʻana o ka alumini sulfate i ka mālama wai a me ka hoʻomaʻemaʻe. Ke hoʻohui ʻia i ka wai, hoʻohui ia i nā haumia microscopic e hui pū i loko o nā ʻāpana nui a nui aʻe. A laila e hoʻopaʻa ʻia kēia mau puʻupuʻu haumia i lalo o ka ipu a i ʻole e nui ka nui e kānana iā lākou mai ka wai. Mālama kēia i ka wai e inu. Ma ke kumu hoʻokahi, hoʻohana ʻia ka alumini sulfate i nā loko ʻauʻau e hoʻemi i ke ao o ka wai.
Na lole hooluu
ʻO kekahi o ka hoʻohana nui ʻana o ka alumini sulfate ma ke kala a me ka paʻi ʻana ma ka lole. Ke hoʻoheheʻe ʻia i loko o ka wai nui i loaʻa ka pH kūʻokoʻa a i ʻole ka liʻiliʻi alkaline, hoʻopuka ka pūhui i kahi mea gooey, alumini hydroxide. ʻO ka mea gooey e kōkua i nā mea pena e hoʻopili i nā lole lole ma o ka hoʻoheheʻe ʻana i ka wai wai. ʻO ke kuleana o ka alumini sulfate, a laila, ʻo ia ka mea pena "hoʻoponopono," ʻo ia ka mea e hui pū me ke ʻano molekala o ka wai a me ka lole i ʻole e pau ka wai i ka wā e pulu ai ka lole.
Hana Pepa
I ka wā ma mua, ua hoʻohana ʻia ka alumini sulfate i ka hana ʻana i ka pepa, ʻoiai ua hoʻololi ka nui o nā mea synthetic. Ua kōkua ka alumini sulfate i ka nui o ka pepa. Ma kēia kaʻina hana, ua hui pū ʻia ka alumini sulfate me ke kopa rosin e hoʻololi ai i ka absorbency o ka pepa. Hoʻololi kēia i nā waiwai ʻīnika o ka pepa. ʻO ka hoʻohana ʻana i ka alumini sulfate, ʻo ia ka mea i hana ʻia ka pepa ma lalo o nā kūlana acidic. ʻO ka hoʻohana ʻana i nā mea hoʻohālikelike synthetic, ʻo ia ka mea hiki ke hana ʻia ka pepa ʻawaʻawa ʻole. ʻAʻole e haki ka pepa ʻakika ʻole e like me ka nui o ka pepa me ka waikawa.
Pehea wau e koho ai i nā kemika kūpono no kaʻu noi?
Hiki iā ʻoe ke haʻi mai iā mākou i kāu hiʻohiʻona noiʻi, e like me ke ʻano o ka loko wai, nā ʻano wai ʻino ʻoihana, a i ʻole ka hana lapaʻau o kēia manawa.
A i ʻole, e ʻoluʻolu e hāʻawi i ka brand a i ʻole ke ʻano o ka huahana āu e hoʻohana nei. E paipai kā mākou hui loea i ka huahana kūpono loa iā ʻoe.
Hiki iā ʻoe ke hoʻouna mai iā mākou i nā laʻana no ka nānā ʻana i ka hale hana, a e hoʻokumu mākou i nā huahana like a i hoʻomaikaʻi ʻia paha e like me kāu mau pono.
Hāʻawi ʻoe i nā lawelawe lepili OEM a pilikino paha?
ʻAe, kākoʻo mākou i ka hana maʻamau i ka hoʻopaʻa inoa ʻana, ka hoʻopili ʻana, ka hana ʻana, etc.
Ua hōʻoia ʻia kāu huahana?
ʻAe. Ua hōʻoia ʻia kā mākou huahana e NSF, REACH, BPR, ISO9001, ISO14001 a me ISO45001. Loaʻa iā mākou nā palapala hōʻoia ʻāina a hana pū me nā hale hana hoa no ka hoʻāʻo SGS a me ka loiloi kalapona.
Hiki iā ʻoe ke kōkua iā mākou e kūkulu i nā huahana hou?
ʻAe, hiki i kā mākou hui ʻenehana ke kōkua i ka hoʻomohala ʻana i nā formula hou a i ʻole ka hoʻonui ʻana i nā huahana i loaʻa.
Pehea ka lōʻihi o kou pane ʻana i nā nīnau?
E pane i loko o 12 mau hola ma nā lā hana maʻamau, a e hoʻopili ma o WhatsApp/WeChat no nā mea wikiwiki.
Hiki iā ʻoe ke hāʻawi i ka ʻike piha i waho?
Hiki ke hāʻawi i ka ʻike piha e like me ka invoice, ka papa inoa packing, ka bila o ka ukana, ka palapala kumu, MSDS, COA, etc.
He aha ka lawelawe ma hope o ke kūʻai aku?
Hāʻawi i ke kākoʻo ʻenehana ma hope o ke kūʻai ʻana, ka hoʻopiʻi ʻana, ka nānā ʻana i ka logistic, hoʻopuka hou a i ʻole ka uku no nā pilikia maikaʻi, etc.
Hāʻawi ʻoe i ke alakaʻi hoʻohana huahana?
ʻAe, me nā ʻōlelo kuhikuhi no ka hoʻohana ʻana, alakaʻi dosing, nā mea hoʻomaʻamaʻa ʻenehana, etc.
