Ua kapa ʻia ʻo Calcium sulfate dihydrate "natural anhydrous gypsum". Huina kemika CaSO4. Kaumaha Molekala 136.14. ʻO nā kristal orthorhombic. Māmā pili 2.960, kuhikuhipuʻuone hulina 1.569, 1.575, 1.613. ʻO kekahi gypsum anhydrous hiki ke hoʻoheheʻe ʻia: ka helu heheʻe 1450 ℃, ka mānoanoa pili 2.89, index refractive 1.505, 1.548, decomposes ke wela keʻokeʻo. ʻIke ʻia kona hemihydrate ʻo "burned gypsum" a me "platinum calciformis", ʻo ka hapa nui ma ke ʻano o ka pauka keʻokeʻo non-crystalline, me ka mānoanoa pili o 2.75. ʻIke pinepine ʻia kona dihydrate ʻo "gypsum", ʻo ia ke aniani keʻokeʻo a i ʻole ka pauka, me ka mānoanoa pili o 2.32, refractive index 1.521, 1.523, 1.530, a nalowale ka wai aniani a pau ke hoʻomehana ʻia i 163 ℃. Puke Kimia Hiki ke hoʻoheheʻe ʻia i ka wai, waika hydrochloric, ʻakika nitric, hiki ke hoʻoheheʻe ʻia i ka ʻakika sulfuric wela, hiki ʻole ke hoʻoheheʻe ʻia i ka waiʻona. Hiki ke hoʻoheheʻe ʻia nā huahana kūlohelohe i ka alkaline sulfate, sodium thiosulfate, a me ka paʻakai ammonium aqueous solutions. Kaʻina hoʻomākaukau: Loaʻa ka gypsum anhydrous kūlohelohe ma ka hana ʻana iā CaO a me SO3 ma lalo o ka wela ʻulaʻula. Loaʻa ka gypsum anhydrous soluble ma ka hoʻomehana ʻana iā CaSO4·2H2O i ke kaumaha mau ma 200 ℃. Loaʻa ka Hemihydrate ma ka calcining a me ka hoʻoheheʻe ʻana i ka gypsum maka. Loaʻa ka dihydrate ma ka hoʻopili ʻana i ka calcium chloride me ka ammonium sulfate. Nā hoʻohana nui o ka calcium sulfate: Hoʻohana nui ʻia ka gypsum anhydrous kūlohelohe i ka lāʻau lapaʻau; hiki ke hoʻohana ʻia ka gypsum anhydrous soluble e like me ka hoʻonani o loko, a hiki ke hoʻohana ʻia e hana i nā kemika, nā mea inu, a pēlā aku; Hoʻohana nui ʻia ka hemihydrate i nā mea kūkulu hale, a hiki ke hoʻohana ʻia e hana i nā kiʻi gypsum a me nā mea seramika; hoʻohana ʻia kāna dihydrate e hana i ka hemihydrate, nā mea hoʻopihapiha, etc.

Hoohana Hana Hana
1. Mea hoʻopaʻa paona: Calcium sulfate dihydrate maikaʻi ka hana ʻana i ka pālākiō a hiki ke hoʻohana ʻia no ka mālama ʻana i ka wai i nā ʻōnaehana ʻoihana e pale i ka scaling i loko o nā paipu a me nā mea hana a mālama i ka hana maʻamau o ka ʻōnaehana.
2. ʻO nā mea hana ʻenehana: Hiki ke hoʻohana ʻia ka calcium sulfate dihydrate ma ke ʻano he mea maka no ka hoʻomākaukau ʻana i nā mea kemika ʻē aʻe, e like me gypsum, gypsum board, gypsum powder, etc.
3. Nā mea kūkulu hale: I ka ʻoihana kūkulu, hiki ke hoʻohana ʻia ka calcium sulfate dihydrate ma ke ʻano he huahana gypsum i nā mea kūkulu hale no ka hoʻonani a hoʻoponopono ʻana i nā paia, nā kaupaku, etc.
4. Mea hana hoʻoili mining: I ka hana ʻana i ka mining, hiki ke hoʻohana ʻia ka calcium sulfate dihydrate ma ke ʻano he mea kōkua i ka flotation a me ka hoʻomaʻemaʻe kaʻina e hāpai i ka hoʻokaʻawale ʻana a me ka hoʻomaʻemaʻe ʻana i nā ores.
Hoohana Mahiai
1. Mea hoʻomaʻamaʻa lepo: Hiki i ka calcium sulfate dihydrate ke hoʻoponopono i ka pH o ka lepo, hoʻomaikaʻi i ke ʻano o ka lepo, hoʻonui i ka momona o ka lepo, a hoʻoikaika i ka ulu ʻana o nā mea kanu.
2. Mea hoʻohui hānai: Ma ke ʻano he kumu calcium, hiki i ka calcium sulfate dihydrate ke hoʻohui i ka mea calcium i nā holoholona a hoʻoikaika i ka ulu holoholona a me ka ulu ʻana o ka iwi.
3. Pesticide raw mea: I ka mahiʻai, hiki ke hoʻohana ʻia ka calcium sulfate dihydrate ma ke ʻano he mea maka no nā pesticides, no ka hoʻomākaukau ʻana i nā insecticides, fungicides, etc.
Hoʻohana lāʻau
1. ʻO nā mea waiwai lāʻau lapaʻau: Hiki ke hoʻohana ʻia ka calcium sulfate dihydrate ma ke ʻano he lāʻau lapaʻau no ka hoʻomākaukau ʻana i nā mea hoʻohui calcium, antacids a me nā lāʻau ʻē aʻe e mālama i ka osteoporosis, hyperacidity a me nā maʻi ʻē aʻe.
2. Lapaʻau Lapaʻau: Hoʻohana pinepine ia e hana i nā kāʻei plaster no ka hoʻoponopono ʻana i ka haki. Loaʻa iā ia ka plasticity maikaʻi a me ke kūpaʻa a kōkua i ka ho'ōla ʻana i nā haki.
3. Nā mea niho: Ma ke kahua o ka dentistry, hiki ke hoʻohana ʻia ka calcium sulfate dihydrate e hana i nā ʻōpala niho a me nā mea hoʻopiha.
4. ʻO nā ʻaʻahu ʻeha: Loaʻa iā ia kekahi o ka wai a me ka ʻae ʻana o ka ea a hiki ke hoʻohana ʻia no ke kāʻei ʻana i kekahi mau ʻeha.
Hoʻohana meaʻai
1. Mea hoʻohui meaʻai: Hiki i ka calcium sulfate dihydrate ke hoʻoponopono i ka pH o ka meaʻai, hoʻonui i ka paʻakikī a me ka ʻono o ka meaʻai, a pāʻani i kahi coagulant i ka hana ʻana i nā meaʻai e like me ka tofu.
2. Preservatives: Hoʻohana ʻia ia no ka mālama mālama ʻana i ka meaʻai, nā mea inu, a me nā mea ʻē aʻe e hoʻonui i ke ola o ka meaʻai.
