Ana amfani da rini mai tarwatsewa kowace rana, amma nan da nan za ku iya cewa, me yasa rinayen tarwatse suke ƙara glacial acetic acid don daidaita PH? (A yanzu ana ƙara Organic acid don daidaita PH, ban da tabo na alkaline.)

Dalili kuwa shine:

Kwanciyar hankali na tarwatsa rini a cikin wanka mai rini yana da alaƙa da ƙimar pH. Musamman a babban zafin jiki da matsa lamba, idan darajar pH na wanka mai launi ba a sarrafa shi sosai ba, sau da yawa zai haifar da bambancin launin launi, manyan dalilai kamar haka.

(1) haifar da accelerated hydrolysis na watsa dyes, a kan aiwatar da rini masana'antu, sau da yawa ƙara wani babban adadin dispersant, kamar diffuser NNO, lignin, sodium carbonate, sabõda haka, rini bayani ne rauni alkaline, a
Lokacin yin rini a 130% high zafin jiki, yana da sauƙi don yin amfani da ruwa, yana haifar da launi mai haske da haske mai haske.
(2) Saboda raguwar bazuwar dyes masu tarwatsewa, asarar rukunin tushe gashi, wannan lamarin galibi yana cikin tsarin azo na rini.
(3) Ƙungiyar phenolic a cikin tsarin kwayoyin halitta na dyes yana haifar da halayen ionic saboda aikin alkali, kuma an inganta narkewar ruwa, yayin da rini na sama ya raunana daidai. Sau da yawa, ruwa mai tarwatsewa na dyes yana da rauni alkaline saboda ƙari na rarrabawa a cikin wankan rini.
