Waxay noqon kartaa marka la furayo wax bannaan ama ay sabab u tahay daadinta haamaha saliidda ama xadhkaha tuubooyinka ee la xidhiidha. Sababtoo ah falcelinta oksaydhka ee saliidda beddelka ayaa dhacda, taas oo la sii dardargelinayo sababtoo ah heerkulka iyo joogitaanka kicinta sida birta, naxaasta iyo xeryahooda macdan ee kala diri ee saliidda beddelka.

Qalabku waxa uu soo saara aashitada biyaha ku milmay & alkali ee muunadda ku jirta isaga oo isticmaalaya biyo la miiray ama xal ethanol ah. Markaa hubi
midabka beddelka dareeraha la soo saaray by methyl orange ama phenolphthalein tilmaame siday u kala horreeyaan, ama go'aami qiimaha pH ee dareeraha la soosaaray iyadoo la isticmaalayo mitir acidity si loo hubiyo in ay jiraan aashitada milmaya iyo alkali ee dareeraha la soosaaray.

Mashiinkayagu wuxuu leeyahay faa'iidooyin hoose:
Naqshad fudud iyo buuxinta shuruudaha GB/T 259.
Awood kuleyliyaha si joogto ah ayaa loo hagaajin karaa. fududahay in la xakameeyo.
