ʻO ka magnesium sulfate heptahydrate, ʻike ʻia hoʻi ʻo sulphobitter, paʻakai ʻawaʻawa, paʻakai cathartic, paʻakai Epsom, formula chemical MgSO4·7H2O), he keʻokeʻo a ʻaʻole waihoʻoluʻu acicular a i ʻole oblique columnar crystals, ʻala ʻole, ʻoluʻolu a ʻawaʻawa iki. Ma hope o ka hoʻoheheʻe ʻia ʻana o ka wela, e hoʻoneʻe mālie ʻia ka wai crystalline i ka magnesium sulfate anhydrous. Hoʻohana nui ʻia ia i ka hana ʻana i ka mea momona, ka ʻili, ka paʻi ʻana a me ke kala, catalyst, papermaking, plastics, porcelain, pigments, match, explosives a me nā mea ahi. Hiki ke hoʻohana ʻia no ka paʻi ʻana a me ke kala ʻana i ka lole pulupulu lahilahi a me ke kilika, ma ke ʻano he mea kaumaha no ka pulupulu siliki a me ka mea hoʻopiha no nā huahana kapok, a hoʻohana ʻia e like me ka paʻakai Epsom i ka lāʻau lapaʻau.
Nā waiwai kino:
ʻO ke ʻano a me nā waiwai: no ka ʻōnaehana kristal rhombic, no nā kihi ʻehā granular a rhombic crystal, colorless, transparent, aggregate no keʻokeʻo, rose a i ʻole aniani ʻōmaʻomaʻo. ʻO ke ʻano he fibrous, acicular, granular a pauka paha. ʻAʻala ʻole, ʻono ʻawaʻawa.
Hiki ke hoʻoheheʻe: Hiki ke hoʻoheheʻe ʻia i ka wai, hiki ke hoʻoheheʻe ʻia i ka ethanol a me ka glycerol.
Nā waiwai kemika:
Paʻa: Paʻa i ka ea humid ma lalo o 48.1 ° C. He maʻalahi ke hoʻokipa i ka ea mahana a maloʻo. Ke kiʻekiʻe aʻe ma mua o 48.1 ° C, nalowale ka wai kristal a lilo i ka sulfate magic. I ka manawa like, ua hoʻokahe ʻia kahi magnesium sulfate. Ma 70-80 ° C, lilo ka wai aniani 4, nalowale 5 wai aniani ma 100 ° C, a nalowale 6 wai aniani ma 150 ° C. Ma 200 ° C Magnesium -like wai sulfate, waiho ʻia nā mea dehydrated i loko o kahi ea humid e hoʻopau hou i ka wai. I loko o ka hoʻonā saturated o ka magnesium sulfate, hiki ke lilo ke aniani i hui pū ʻia me ka wai me 1, 2, 3, 4, 5, 6, a me 12 wai. I loko o -1.8 ~ 48.18 ° C saturated aqueous solution, ua hoʻokuʻu ʻia ka magnesium sulfate, a i loko o ka hoʻonā wai saturated o 48.1 a 67.5 ° C, ua hoʻokahe ʻia ka magnesium sulfate. Ke kiʻekiʻe aʻe ma mua o 67.5 ° C, ua hoʻoheheʻe ʻia kahi magnesium sulfate. ʻO ka hoʻoheheʻe malihini ma waena o ° C a me ka magnesium sulfate o ʻelima a ʻehā wai sulfate i hana ʻia. Hoʻololi ʻia ka Magnesium sulfate i magnesium sulfate ma 106 ° C. Ua hoʻololi ʻia ka magnesium sulfate i ka magnesium sulfate ma 122-124 ° C. Hoʻololi ʻia ka magnesium sulfate i ka magnesium sulfate paʻa ma 161 ～ 169 ℃.

Ke noi nui:
1) kahua meaʻai
Ma ke ʻano he mea hoʻoikaika meaʻai. hiki ke hoʻohana ʻia nā lula o koʻu ʻāina no nā huahana waiu, me ka nui o 3 a 7g/kg; ʻO ka nui o ka hoʻohana ʻana i nā wai inu a me nā mea inu waiu he 1.4 ～ 2.8g/kg; ʻO ka nui o ka hoʻohana ʻana i nā mea inu mineral he 0.05g/kg.
2) kahua ʻoihana
Hoʻohana nui ʻia me ka paʻakai calcium no ka wai makuahine. Hiki i ka hoʻohui ʻana i ka wai 4.4g/100L ke hoʻonui i ka paʻakikī ma 1 degere. Ke hoʻohana ʻia, hiki iā ia ke hana i ka ʻawaʻawa a hana i ka ʻala hydrogen sulfide.
Hoʻohana ʻia e like me ka leo, nā mea pahū, ka hana pepa, porcelain, fertilizer, a me nā lāʻau lapaʻau waha, etc., nā mea hoʻohui wai mineral.
3) Kihapai mahiai
Hoʻohana ʻia ka Magnesium sulfate i kahi mea kanu i ka mahiʻai no ka mea ʻo ka magnesium kekahi o nā mea nui o ka chlorophyll. Hoʻohana pinepine ʻia nā hua o nā mea kanu i loko o ka ipuhao a i ʻole ka magnesium, e like me nā ʻōmato, ʻuala, nā rosa, a me nā mea ʻē aʻe. Hoʻohana ʻia ka Magnesium sulfate e like me ka paʻakai ʻauʻau.
Kaʻina hoʻomākaukau:
1) Hana 1:
Hoʻohui ʻia ka sulfuric acid i ka magnesium carbonate maoli (magnesite), hoʻoneʻe ʻia ke kalapona dioxide, recrystallized, hoʻoheheʻe ʻia ʻo Kieserite (MgSO4·H2O) i loko o ka wai wela a hana hou ʻia, i hana ʻia mai ka wai kai.
2) Keʻano 2 (Keʻano hoʻolei wai kai)
Ma hope o ka hoʻoheheʻe ʻia ʻana o ka brine e ke ʻano brine, hana ʻia ka paʻakai kiʻekiʻe, a ʻo kona haku ʻana ʻo MgSO4>. 30 pakeneka. 35%, MgCl2 ma kahi o 7%, KCl ma kahi o 0.5%. Hiki ke hoʻoheheʻe ʻia ka ʻawaʻawa me ka solution MgCl2 o 200g/L ma 48 ℃, me ka hoʻonā NaCl liʻiliʻi a me ka hopena MgSO4 hou aʻe. Ma hope o ka hoʻokaʻawale ʻana, ua hoʻoheheʻe ʻia ka MgSO4 · 7H2O crude e ka hoʻomaha ʻana ma 10 ℃, a loaʻa ka huahana i hoʻopau ʻia e ka recrystallization lua.
