Calcium sulfate hemihydrate CAS 10034-76-1
Kapa ʻia ka calcium sulfate he gypsum maka, gypsum maka paʻakikī, Muriacite, gypsum anhydrous. Nā kristal orthorhombic kala ʻole (ʻano β) a i ʻole nā kristal monoclinic (ʻano α). Kaumaha molekalale pili 136.14. Māmā pili 2.960. Ka helu heheʻe 1193 ℃ (hoʻololi ʻia mai ke ʻano β a i ke ʻano α), 1450 ℃ (ʻano α, a decomposed). Hiki ke hoʻoheheʻe ʻia i ka wai (0.209 ma 20 ℃), hiki ke hoʻoheheʻe ʻia i ka waikawa, ka paʻakai ammonium, ka sodium thiosulfate, ka solution sodium chloride a me ka glycerol. ʻOiai inā hoʻohui ʻia ka wai, ʻaʻole hiki ke lilo hou i ka calcium sulfate dihydrate. Inā maloʻo loa ka ʻaila gypsum maoli ma lalo o 300 ℃, hiki ke hoʻoulu ʻia ka gypsum anhydrous soluble i ka wai; inā hoʻomehana ʻia ka gypsum kūlohelohe ma luna o 600 ℃, hana ʻia ka gypsum anhydrous insoluble. Ke hui ʻia ka calcium sulfate anhydrous a i ʻole ka plaster o Paris me ka nui o ka wai kūpono, paʻa mālie ia. Hoʻohana ʻia ia e like me ka retarder, adhesive, moisture absorbent, polishing powder, pepa hoʻopiha, gas desiccant, plaster bandage, a me ka hana lima. Hoʻohana ʻia ʻo Gypsum ma ke ʻano he mea maka no ka hana ʻana i ka sima, a hiki iā ia ke hoʻololi i ka manawa hoʻonohonoho o ka sima. Hoʻohana ʻia ia ma ke ʻano he coagulant i ka hana tofu, ka meaʻai hū, ka mea hoʻoponopono palaoa, a me ka chelating agent. Aia nā mines gypsum maoli, a ʻo nā huahana o ka ʻoihana phosphate he calcium sulfate. Hoʻopili ka solution ammonium sulfate me ka solution calcium chloride, a hiki i ka kānana, ka holoi ʻana a me ka ua hiki ke hana i kahi huahana maʻemaʻe.

Kaʻina meaʻai:
Hiki ke hoʻohana ʻia ka calcium sulfate ma ke ʻano he lāʻau lapaʻau palaoa (ma ke ʻano he diluent no benzoyl peroxide), me ka nui o ka hoʻohana ʻana he 1.5 grams no ka kilo; hoʻohana ʻia ia ma ke ʻano he coagulant i ka hana ʻai. Hoʻohana ʻia ia no ka hana ʻana i ka tofu, a ma kahi o 14-20 grams no ka lita o ka soybeans e hoʻohui ʻia i ka waiū soy (ʻo ka nui o ka nui e hoʻopuka ai i ka ʻawaʻawa). Hoʻohui ʻia ia i ka palaoa palaoa ma 0.15% a hoʻohana ʻia e like me ka meaʻai hū a me ka mea hoʻoponopono palaoa. Hoʻohui ʻia i nā ʻōmato a me nā ʻuala i hoʻopaʻa ʻia i ka ʻiʻo. Hoʻohana ʻia ʻo ia ma ke ʻano he wai paʻakikī a hoʻonui i ka ʻono no ka hana ʻana i ka pia. Hiki ke hoʻohana ʻia ma ke ʻano he meaʻai meaʻai.
Hana ʻenehana:
1. ʻOihana hana: Hiki ke hoʻohana ʻia ka calcium sulfate i ka ʻoihana kūkulu hale, nā mea hoʻonaninani wela, nā uhi, nā mea hoʻoikaika, a me nā mea ʻē aʻe. Hoʻohana ʻia ia ma ke ʻano he mea ikaika mua i nā admixtures koneki, maʻamau me kahi ʻano o kahi o 3%, e hoʻoponopono i ka manawa hoʻonohonoho a hui ʻia a wili i ka sima. Ke hoʻohui ʻia ka calcium sulfate i ke kaʻa, he hopena ikaika koʻikoʻi kona.
2. ʻOihana hana pepa: Hoʻohana ʻia ka calcium sulfate i ka ʻoihana pepa e pani i kahi hapa a i ʻole ka hapa nui o ka pulp. Hiki ke hoʻohana ʻia ka calcium sulfate me kahi ratio o ka liʻiliʻi a i ʻole like me 50 ma ke ʻano he hoʻopiha piha kiʻekiʻe no ka pepa, hiki ke hoʻonui nui i ka hana pepa, hoʻemi i ka ʻai lāʻau, a kōkua i ka pale ʻana i ke kaiapuni a hōʻemi i ka pollution wai.
3. ʻOihana Kemika: I ka ʻoihana kemika, hiki ke hoʻohana ʻia i mea hoʻoikaika. Hiki ke hoʻohana ʻia nā ʻumi ʻumi calcium sulfate anhydrous i loko o ka granulation plastic e hoʻonui ai i ka ikaika o nā ʻāpana palaka, ke kūpaʻa wela kiʻekiʻe, a e hoʻemi i nā kumukūʻai. I ka hana ʻana o nā plastics e like me polyvinyl chloride, polyethylene, propylene, a me ka polystyrene, hiki iā ia ke hoʻonui i ka hana o nā ʻano like ʻole o ka huahana, hoʻomaikaʻi i ka fineness, dimensional stability, surface finish, tensile strength, bending strength, bending elastic modulus and thermal deformation temperature, a hoʻemi i ka lole lole. Ma ke ʻano he mea hoʻopiha asphalt, hiki ke hoʻonui nui i ka wahi palupalu o ka asphalt.
Mahiai:
Hiki ke hoʻohana ʻia ka calcium sulfate ma ke ʻano he mea kanu i ka mahiʻai e hōʻemi i ka alkalinity lepo a hoʻomaikaʻi i ka hana lepo.
lāʻau lapaʻau:
Loaʻa i ka calcium sulfate nā noi like ʻole i ka ʻoihana lāʻau. Hiki ke hoʻohana ʻia e hoʻomākaukau i nā lāʻau lapaʻau a hāʻawi i nā mea pono a me nā waiwai no nā lāʻau lapaʻau. Eia kekahi, hoʻohana ʻia ka calcium sulfate e hana i nā papa e hōʻoia i ka paʻa a me ka pono o nā papa. I ka manawa like, ua hoʻohui pū ʻia i ka toothpaste e hoʻonui ai i ka haku ʻana a me ka hana o ka toothpaste. Hōʻike kēia mau noi i ke koʻikoʻi o ka calcium sulfate i ka ʻoihana lāʻau lapaʻau, e hāʻawi ana i nā mea nui a me nā waiwai no nā huahana lāʻau.
