Heptahydrate ya manyeziyumu sulfate, izwi kandi nka sulphobitter, umunyu usharira, umunyu wa cathartic, umunyu wa Epsom, formula ya shimi MgSO4·7H2O), ni kristu z'umweru cyangwa zidafite ibara cyangwa zikozwe mu buryo bwa acicular cyangwa oblique, nta mpumuro, akonje kandi asharira gato. Nyuma yo kubora ubushyuhe, amazi ya kristu agenda akurwamo buhoro buhoro muri sulfate ya manyeziyumu idahumeka. Akoreshwa cyane cyane mu gukora ifumbire, uruhu, gucapa no gusiga irangi, gukamura, gukora impapuro, pulasitiki, porcelain, irangi, ibisasu, ibiturika n'ibikoresho bidashya. Ashobora gukoreshwa mu gucapa no gusiga irangi igitambaro cyoroheje cya kotoni na silk, nk'ikintu gipima uburemere bwa kotoni na silk byuzuza ibicuruzwa bya kapok, kandi agakoreshwa nk'umunyu wa Epsom mu buvuzi.
Imiterere ifatika:
Imiterere n'imiterere: ni kristu ya rhombic, ifite impande enye z'urubara cyangwa kristu ya rhombic, idafite ibara, ibonerana, ivanze kugira ngo ikirahuri cyera, iroza cyangwa icyatsi kibisi kibengerane. Ishusho ni fibrous, acicular, granular cyangwa ifu. Ifite impumuro mbi, uburyohe busharira.
Gushonga: Bishongera mu mazi byoroshye, bishongera gato muri ethanol na glycerol.
Imiterere y'ibinyabutabire:
Gutuza: Ihamye mu mwuka ushushe uri munsi ya 48.1 ° C. Biroroshye kuyishyira mu mwuka ushyushye kandi wumye. Iyo irenze 48.1 ° C, itakaza amazi ya kristu maze ikaba sulfate y'igitangaza. Muri icyo gihe, sulfate ya manyeziyumu iragwa. Kuri 70-80 ° C, itakaza amazi 4 ya kristu, itakaza amazi 5 ya kristu kuri 100 ° C, naho amazi 6 ya kristu yatakaye kuri 150 ° C. Kuri 200 ° C sulfate y'amazi ya manyeziyumu, ibintu byakuwemo amazi bishyirwa mu mwuka ushushe kugira ngo byongere binywe amazi. Mu gisubizo cyuzuye cya magnesium sulfate, kristalo ivanze n'amazi hamwe na 1, 2, 3, 4, 5, 6, na 12 amazi ashobora kuba kristu. Muri -1.8 ~ 48.18 ° C amazi yuzuye, sulfate ya manyeziyumu iragwa, naho mu gisubizo cyuzuye cy'amazi kuva kuri 48.1 kugeza 67.5 ° C, sulfate ya manyeziyumu iragwa. Iyo ubushyuhe burenze 67.5 ° C, sulfate ya manyeziyumu irashongeshwa. Hakozwe sulfate ya manyeziyumu hagati ya ° C na sulfate ya manyeziyumu ya sulfate y'amazi itanu cyangwa ane. Sulfate ya manyeziyumu yahinduwe sulfate ya manyeziyumu kuri 106 ° C. Sulfate ya manyeziyumu yahinduwe sulfate ya manyeziyumu kuri 122-124 ° C. Sulfate ya manyeziyumu ihinduka sulfate ya manyeziyumu ihamye kuri 161 ~ 169 ℃.

Porogaramu nyamukuru:
1) Umurima w'ibiribwa
Nk'umuti wongera imbaraga mu biryo. Amategeko agenga igihugu cyanjye ashobora gukoreshwa ku bikomoka ku mata, afite ingano iri hagati ya 3 na 7g/kg; ingano y'ikoreshwa mu binyobwa n'ibinyobwa by'amata ni 1.4 ～ 2.8g/kg; ikoreshwa ntarengwa mu binyobwa by'imyunyu ngugu ni 0.05g/kg.
2) Urwego rw'inganda
Ikoreshwa cyane hamwe n'umunyu wa kalisiyumu mu mazi y'umubyeyi wa divayi. Kongeramo 4.4g/100L y'amazi bishobora kongera ubukana bwa dogere imwe. Iyo ikoreshejwe, ishobora kurura kandi igatanga impumuro ya hydrogen sulfide.
Ikoreshwa nk'inyongeramusaruro z'amazi y'ubutare, ibisasu, gukora impapuro, porcelain, ifumbire, n'ibindi, nk'inyongeramusaruro z'amazi y'ubutare.
3) Ubuhinzi
Sulfate ya Magnesium ikoreshwa mu ifumbire mu buhinzi kuko manyeziyumu ari kimwe mu bintu by'ingenzi bigize chlorophyll. Ibihingwa by'ibimera biri mu nkono cyangwa manyeziyumu bikunze gukoreshwa, nk'inyanya, ibirayi, indabyo z'amaroza, n'ibindi. Sulfate ya Magnesium ifite ubushobozi bwo gushonga cyane ugereranije n'izindi fumbire. Sulfate ya Magnesium nayo ikoreshwa nk'umunyu wo mu bwogero.
Uburyo bwo gutegura:
1) Uburyo bwa 1:
Aside sulfuriki yongerwa muri magnesium carbonate karemano (magnesite), dioxyde de carbone irakurwaho, ikongera gushyirwamo, Kieserite (MgSO4·H2O) ishongeshwa mu mazi ashyushye hanyuma ikongera gushyirwamo, ikozwe mu mazi yo mu nyanja.
2) Uburyo bwa 2 (Uburyo bwo gusohora amazi yo mu nyanja)
Nyuma y’uko amazi y’umunyu ashize umwuka hakoreshejwe uburyo bwa marine, umunyu ushyushye cyane urakorwa, kandi ibigizemo ni MgSO4>. 30%, MgCl2 hafi 7%, KCl hafi 0.5%. Ibinure bishobora gukurwamo umuti wa MgCl2 wa 200g/L kuri 48℃, hamwe n’umuti wa NaCl muto n’umuti wa MgSO4 mwinshi. Nyuma yo gutandukana, MgSO4·7H2O yakuwemo umwuka binyuze mu gukonjesha kuri 10℃, kandi umusaruro warangiye uboneka hakoreshejwe uburyo bwa kabiri bwo kongera gukonjesha.
3) Uburyo bwa 3 (Uburyo bwa aside sulfuriki)
Mu gikoresho cyo gupima, rhombotrite yongewemo buhoro buhoro mu mazi no mu nzoga y’umubyeyi, hanyuma irangizwa na aside sulfurike. Ibara ryahindutse kuva ku ibara ry’ubutaka rijya ku mutuku. pH yagenzuwe igera kuri Be 5, kandi ubucucike bwari 1.37 ~ 1.38 (39 ~ 40° Be). Umuti wo gupima wayunguruwe kuri 80°C, hanyuma pH ihindurwa kuri 4 hamwe na aside sulfurike, hongerwamo kristu zikwiye z’imbuto, hanyuma zikonjeshwa kuri 30°C kugira ngo zihindurwe. Nyuma yo gutandukanya, umusaruro urangiye wumishwa kuri 50 ~ 55°C, hanyuma inzoga y’umubyeyi igasubizwa mu gikoresho cyo gupima. Magnesium sulfate heptahydrate ishobora kandi gutegurwa hakoreshejwe uburyo bwo gupima aside sulfurike nke hamwe na magnesia 65% muri momorrhea binyuze mu kuyungurura, kuvura, gupima, gupima, gutandukanya centrifugal no kuma, ikorwa muri magnesium sulfate.
Igereranya ry'ibinyabutabire by'inyito: MgO+H2SO4+6H2O→MgSO4·7H2O.
Amabwiriza yo kwirinda gutwara abantu:Ipaki igomba kuba yuzuye mu gihe cyo gutwara, kandi imizigo igomba kuba ifite umutekano. Mu gihe cyo gutwara, menya neza ko agakoresho katagomba gusohoka, gusenyuka, kugwa, cyangwa kwangirika. Birabujijwe cyane kuvanga aside n'imiti iribwa. Mu gihe cyo gutwara, igomba kurindwa izuba, imvura n'ubushyuhe bwinshi. Ikinyabiziga kigomba gusukurwa neza nyuma yo gutwara.
Ingamba zo kwirinda mu mikorere:Gufunga no kongera imbaraga mu guhumeka. Umukoresha agomba gukurikiza amabwiriza y’imikorere nyuma y’amahugurwa yihariye. Ni byiza ko abakora akazi bambara udupfukamunwa two kwiyungurura, indorerwamo zo kwirinda uburozi, kwambara imyenda yo gukora irwanya uburozi, n’uturindantoki twa kabutura. Irinde ivumbi. Irinde ko habaho aside. Shyiraho agapfukamunwa gato kugira ngo wirinde ko ipfunyika yangirika. Ifite ibikoresho byo kuvurwa byihutirwa. Ibikoresho birimo ubusa bishobora kuba ibisigazwa byangiza. Iyo ivumbi riri mu kirere rirenze urugero, tugomba kwambara agapfukamunwa ko kwiyungurura. Iyo ubutabazi bwihutirwa cyangwa kwimura abantu, kwambara udupfukamunwa two kwirinda virusi bigomba kwambarwa.
Ibipimo byo kwirinda kubika:Bika mu bubiko bukonje kandi bufite umwuka mwiza. Irinde umuriro n'ubushyuhe. Bika ukwabyo ahantu hadakoreshejwe aside kandi wirinde ko bibikwa mu buryo buvanze. Aho bibikwa hagomba kuba hari ibikoresho bikwiye kugira ngo bikingire amazi.
