Aluminium Sulfate
Hordhaca aluminium sulfate
Aluminium sulfate waa milix leh qaacidada Al2(SO4)3. Waxay ku milmi kartaa biyaha waxaana inta badan loo isticmaalaa sidii wakiilka xinjirowga ah ee sifaynta biyaha la cabbo iyo biyaha wasakhda ah, iyo sidoo kale soo saarista waraaqaha. Aluminium Sulfate-kayaga waxa uu leeyahay budo budo ah, jajabyo, iyo kiniinno, waxaanu sidoo kale bixin karnaa wax-ferric, ferric hoose, iyo heer warshadeed.
Aluminium sulfate wuxuu u jiraa sida cad, kiristaalo dhalaalaya, granules, ama budo. Dabeecadda, waxay u jirtaa sida macdanta alunogenite. Aluminium sulfate waxaa mararka qaarkood loo yaqaan alum ama warqad sameeyaha.

Isticmaalka Qoyska
Qaar ka mid ah isticmaalka ugu caansan ee aluminium sulfate ayaa laga helaa guriga dhexdiisa. Xarunta waxaa inta badan laga helaa baking soda, inkastoo ay jiraan xoogaa muran ah oo ku saabsan inay ku habboon tahay in lagu daro aluminium cuntada. Qaar ka mid ah dawooyinka lidka ku ah waxay ka kooban yihiin aluminium sulfate sababtoo ah sifooyinka bakteeriyada bakteeriyada, inkasta oo laga bilaabo 2005 FDA aysan u aqoonsanayn qoyaan yareeya. Ugu dambeyntii, xaruntu waa maaddada astringent ee qalin-qoritaan, kuwaas oo loogu talagalay in lagu joojiyo jeexjeexyada yaryar ee dhiig-baxa.
Beerista
Isticmaalka kale ee xiisaha leh ee aluminium sulfate agagaarka guriga ayaa ku jira beerta. Sababtoo ah aluminium sulfate waa mid aad u acidic ah, mararka qaarkood waxaa lagu daraa carrada alkaliinka ah si loo dheellitiro pH ee dhirta. Marka aluminium sulfate la yimaado biyaha, waxay samaysaa aluminium hydroxide iyo xal sulfuric acid ah oo la badhxay, kaas oo beddela asiidhka ciidda. Beeralayda beera hydrangeas waxay dabaqaan hantidan si ay u beddelaan midabka ubaxa (buluug ama casaan) ee hydrangeas maadaama geedkan uu aad ugu nugul yahay pH-ga ciidda.
Aluminium Sulfate Daaweynta Biyaha
Mid ka mid ah isticmaalka ugu muhiimsan ee aluminium sulfate waa daaweynta biyaha iyo nadiifinta. Marka lagu daro biyaha, waxay sababtaa wasakhda yar yar inay isku ururto qaybo waaweyn iyo qaybo waaweyn. Kuruubyada wasakhda ah waxay dagi doonaan gunta weelka ama ugu yaraan way weynaan doonaan si ay uga sifeeyaan biyaha. Tani waxay ka dhigaysaa biyaha kuwo ammaan ah oo la cabbo. Isla mabda'a, aluminium sulfate ayaa sidoo kale mararka qaarkood loo isticmaalaa barkadaha dabaasha si loo yareeyo daruuraha biyaha.
Dharka midabaynta
Mid kale oo ka mid ah isticmaalka badan ee aluminium sulfate ayaa ah midabaynta iyo daabacaadda marada. Marka lagu milmo xaddi badan oo biyo ah oo leh pH dhexdhexaad ah ama waxoogaa alkaline ah, xaruntu waxay soo saartaa walax gooey ah, aluminium hydroxide. Walaxda gooey waxay caawisaa dheeha in ay ku dhegaan fiilooyinka marada iyada oo ka dhigaysa biyaha dheeha kuwo aan milmi karin. Doorka aluminium sulfate, markaa, waa sida dheeha "fixer", taas oo macnaheedu yahay in ay ku darayso qaabka molecular ee dheeha iyo dharka si uusan dheehu u dhammaanin marka maradu qoyan tahay.
Warqad Samaynta
Waagii hore, aluminium sulfate ayaa loo isticmaali jiray samaynta warqadda, in kasta oo walxaha synthetic ay badi beddeleen. Aluminium sulfate waxay caawisay xajmiga warqadda. Habkan, aluminium sulfate ayaa lagu daray saabuunta rosin si loo beddelo nuugista warqadda. Tani waxay beddeshaa sifooyinka khad nuuga ee warqadda. Isticmaalka aluminium sulfate macnaheedu waa in warqadda lagu sameeyay xaalado acidic ah. Isticmaalka walxaha cabbiraadda synthetic waxay ka dhigan tahay in warqad aan aashito lahayn la soo saari karo. Warqada aan aashitada lahayni uma jabto sida ugu dhakhsaha badan ee warqada leh aashitada.
