(1) Ana iya amfani da gishiri don inganta rini.

(2), wakili mai daidaita launi na cationic da ma'aunin gyaran launi na ƙarfe don haɓaka saurin sauri.

2, kama da rini na VAT

(1), rini yana buƙatar ragewa zuwa leachite tare da wakili mai ragewa don rina fiber da oxidize akan fiber. Maimakon wakili mai ƙarfi mai ragewa, sodium sulfur wakili ne mai rauni mai rauni. Koyaya, mallakin kai tsaye na leaches zuwa zaruruwa bayan raguwa ya yi ƙasa da na rini na VAT, kuma yanayin haɗar rini ya fi girma.

(2) Halin da acid zai iya haifar da H2S gas, da kuma dauki tare da aluminum acetate iya samar da baki aluminum sulfur hazo.

3, za a iya amfani da mafi girman zafin jiki don inganta yawan yaduwa na rini da inganta matakin shiga.
