Aluminium Sulfate
Kenyelletso ea Aluminium sulfate
Aluminium sulfate ke letsoai le nang le foromo ea Al2(SO4)3. E qhibiliha ka metsing 'me e sebelisoa haholo-holo e le ntho e kopanyang ho hloekisa metsi a nooang le limela tsa ho hloekisa metsi a litšila, hape le ho etsa pampiri. Aluminium Sulphate ea rona e na le li-granules tsa phofo, li-flakes le matlapa, hape re ka fana ka maemo a se nang ferric, a tlase-tlase, le a indasteri.
Aluminium sulfate e teng e le bosoeu, likristale tse benyang, granules, kapa phofo. Ka tlhaho, e teng e le mineral alunogenite. Aluminium sulfate ka linako tse ling e bitsoa alum kapa papermaker's alum.

Lisebelisoa tsa Lapeng
Tse ling tsa litšebeliso tse tloaelehileng tsa aluminium sulfate li fumanoa ka tlung. Hangata motsoako o fumanoa ka soda ea ho baka, le hoja ho na le likhang mabapi le hore na ho loketse ho eketsa aluminium lijong. Li-antiperspirant tse ling li na le aluminium sulfate ka lebaka la thepa ea eona ea antibacterial, le hoja ho tloha ka 2005 FDA ha e e hlokomele e le e fokotsang metsi. Qetellong, motsoako ona ke motsoako oa astringent oa lipensele tsa styptic, tse etselitsoeng ho thibela maqeba a manyenyane ho tsoa mali.
Ho lema
Lisebelisoa tse ling tse khahlisang tsa aluminium sulfate ho potoloha ntlo ke ho lema. Hobane aluminium sulfate e na le asiti haholo, ka linako tse ling e eketsoa mobung o nang le alkaline haholo ho leka-lekanya pH ea limela. Ha aluminium sulfate e kopana le metsi, e etsa aluminium hydroxide le motsoako oa diluted sulfuric acid, o fetolang asiti ea mobu. Balemi ba lirapa ba lemang hydrangea ba sebelisa setša sena ho fetola 'mala oa lipalesa (o putsoa kapa o pinki) oa hydrangeas kaha semela sena se na le bothata ba mobu pH.
Phekolo ea Metsi a Aluminium Sulfate
E 'ngoe ea litšebeliso tsa bohlokoa ka ho fetisisa tsa aluminium sulfate ke ho hloekisa metsi le ho hloekisa. Ha e kenngoa metsing, e etsa hore litšila tse nyenyane haholo li kopane ho ba likaroloana tse kholoanyane le tse khōloanyane. Litšila tsena li tla lula tlase ho sejana kapa bonyane li be kholo ho lekana ho li sefa ka ntle ho metsi. Sena se etsa hore metsi a bolokehe ho noa. Ka mokhoa o ts'oanang, aluminium sulfate ka linako tse ling e sebelisoa matamong a ho sesa ho fokotsa maru a metsi.
Masela a ho daea
E 'ngoe ea litšebeliso tse ngata tsa aluminium sulfate ke ho daea le ho hatisa lesela. Ha e qhibiliha ka bongata ba metsi a nang le pH e sa nke lehlakore kapa ea alkaline hanyenyane, motsoako o hlahisa ntho ea gooey, aluminium hydroxide. Ntho ea gooey e thusa dae ho khomarela likhoele tsa lesela ka ho etsa hore metsi a dae a se ke a qhibiliha. Ka hona, karolo ea aluminium sulfate e tšoana le “sefetoleli” sa dae, ho bolelang hore e kopana le sebōpeho sa limolek’hule tsa dae le lesela e le hore dae e se ke ea fela ha lesela le koloba.
Ho Etsa Lipampiri
Nakong e fetileng, aluminium sulfate e ne e sebelisoa ha ho etsoa pampiri, le hoja li-synthetic agents li nkile sebaka sa eona. Aluminium sulfate e thusitse boholo ba pampiri. Ts'ebetsong ena, aluminium sulfate e ne e kopantsoe le sesepa sa rosin ho fetola monyetla oa pampiri. Sena se fetola thepa ea pampiri e monyang enke. Ho sebelisa aluminium sulfate ho bolela hore pampiri e entsoe tlas'a maemo a acidic. Tšebeliso ea li-synthetic sizeing agents e bolela hore pampiri e se nang acid e ka hlahisoa. Pampiri e se nang asiti ha e robehe ka potlako joaloka pampiri e boholo bo nang le asiti.
