Aluminium sulfate
Kutanga kweAluminium sulfate
Aluminium sulfate munyu une fomula Al2(SO4)3.Iyo inonyungudika mumvura uye inonyanya kushandiswa seyakagadzika mumiriri mukucheneswa kwemvura yekunwa uye zvidyarwa zvekuchenesa mvura, uye zvakare mukugadzira mapepa.Yedu Aluminium Sulphate ine poda granules, flakes, uye mahwendefa, isu zvakare tinokwanisa kupa isina-ferric, yakaderera-ferric, uye giredhi remaindasitiri.
Aluminium sulfate iripo sechena, makristasi anopenya, magranules, kana hupfu.Muzvisikwa, iripo semineral alunogenite.Aluminium sulfate dzimwe nguva inonzi alum kana papermaker's alum.

Zvishandiso Zvemumba
Zvimwe zvezvinonyanya kushandiswa zvealuminium sulfate zvinowanikwa mukati memba.Komboni yacho inowanzowanikwa mukubika soda, kunyangwe paine gakava pamusoro pekuti zvakakodzera here kuwedzera aluminium pakudya.Mamwe antiperspirants ane aluminium sulfate nekuda kweayo antibacterial properties, kunyangwe kubva muna 2005 iyo FDA isingazvizive seinoderedza kunyorova.Chekupedzisira, komboni iyi ndiyo ine astringent ingredient muma styptic penzura, ayo akagadzirirwa kumisa madiki madiki kubuda ropa.
Kurima bindu
Kumwe kushandiswa kunonakidza kwealuminium sulfate kutenderedza imba kuri mukurima.Nekuti aluminium sulfate yakanyanya acidic, dzimwe nguva inowedzerwa kune yakanyanya alkaline ivhu kuenzanisa pH yezvirimwa.Kana aruminiyamu sulfate ikasangana nemvura, inoumba aruminiyamu hydroxide uye yakanyungudutswa sulfuric acid mhinduro, inoshandura acidity yevhu.Varimi veminda vanodyara hydrangeas vanoshandisa ichi chivakwa kuti vachinje ruvara rweruva (ruvara rwebhuruu kana pink) ye hydrangeas sezvo chirimwa ichi chinobata zvakanyanya ivhu pH.
Aluminium SulfateWater Kurapa
Imwe yeanonyanya kukosha kushandiswa kwealuminium sulfate iri mukurapa kwemvura uye kuchenesa.Kana yawedzerwa kumvura, inokonzera tsvina yemicroscopic kuungana kuita zvidimbu zvihombe uye zvakakura.Zvimedu zvetsvina izvi zvinozogara pasi pegaba kana kuti zvakakura zvekutozvisefa kunze kwemvura.Izvi zvinoita kuti mvura ive isina njodzi pakunwa.Pane imwecheteyo musimboti, aluminium sulfate dzimwe nguva inoshandiswa mumadziva ekushambira kuderedza kusviba kwemvura.
Micheka Dyeing
Imwe yekushandiswa kwakawanda kwealuminium sulfate ndeyekudhaya uye kudhinda pamachira.Kana yanyungudutswa muhuwandu hwemvura ine isina kwayakarerekera kana zvishoma alkaline pH, musanganiswa unoburitsa gooey substance, aluminium hydroxide.Iyo gooey substance inobatsira madhayi kunamira kumachira eshinda nekuita kuti dhayi isanyungudika mvura.Basa realuminium sulfate, zvino, rakaita se “mugadzirisi wedhayi,” zvichireva kuti inosanganiswa nechimiro chemolecular yedhayi nemucheka kuitira kuti dhayi irege kupera kana jira ranyorova.
Kugadzira Mapepa
Munguva yakapfuura, aluminium sulfate yaishandiswa mukugadzira mapepa, kunyange zvazvo majekiseni ekugadzira ainyanya kuitsiva.Aluminium sulfate yakabatsira pakukura kwepepa.Mukuita uku, aluminium sulfate yakasanganiswa nesipo yerosin kushandura kunyura kwepepa.Izvi zvinoshandura inki-inobata zvimiro zvebepa.Kushandisa aluminium sulfate zvinoreva kuti bepa rakagadzirwa pasi pemamiriro ane acidic.Iko kushandiswa kwemasynthetic sizing agents kunoreva kuti mapepa asina acid anogona kugadzirwa.Bepa risina asidi hariparare nekukurumidza sepepa rakaenzana neasidhi.
