Ana amfani da rini na tarwatsewa kowace rana, amma nan da nan za ku iya cewa, me yasa ake watsa rini da glacial acetic acid don daidaita PH? (A yanzu ana ƙara Organic acid don daidaita PH, ban da rini 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 tarwatsa dyes, a cikin masana'antu aiwatar da dyes, sau da yawa ƙara wani babban adadin dispersants kamar watsawa wakili NNO, lignin, sodium carbonate, da dai sauransu, sabõda haka, da rini ne weakly alkaline, a cikin
Lokacin yin rini a 130% high zafin jiki, yana da sauƙi don yin amfani da ruwa, yana haifar da launi mai haske da launin launi.
(2) Saboda raguwar bazuwar rini mai tarwatsewa, asarar rukunin chromophore, wannan lamari yakan kasance a cikin rini tare da tsarin azo.
(3) Rukunin phenolic a cikin tsarin kwayoyin halitta na rini yana haifar da amsawar ionic saboda aikin alkali, ana inganta narkewar ruwa, kuma rini yana raunana daidai da haka, sau da yawa saboda ƙara mai rarrabawa a cikin wanka mai rini. , yana haifar da tarwatsawa na rini tare da raunin alkaline.
