Wasu rini na tarwatsewar ja suna da saurin sake sakewa a ƙarshen rini, koda kuwa hankalinsu ya yi ƙasa da matakin jikewa, musamman lokacin rina launuka masu duhu.Musamman lokacin yin rini da ruwa mai wuya, yana da sauƙin chelate da ions ƙarfe.Sakamakon chelate yana da ƙarancin narkewa a ƙarƙashin yanayin rini kuma zai bar ɗigon shuɗi ko ɗigon launi akan masana'anta.
Abubuwan da ke haifar da recystallization
Auxiliaries, winding oil, alkaline residues, da dai sauransu da aka kara a lokacin kadi.Ana iya guje wa waɗannan matsalolin ta hanyar tacewa kafin yin rini ko ƙara abubuwa masu lalata a cikin wankan rini.Da zarar tabo ta faru, ana iya kawar da shi ta hanyar tsaftacewa ta raguwar alkaline ko maganin acid.
3. Agglomeration da Mayar da hankali
Abubuwan da ke ba da gudummawa
Yana raunana tasirin narkar da mai watsawa, yana rage rikitar da wutar lantarki, kuma yana ƙara yawan haɗuwa da barbashi rini da haɓaka ƙarfin motsin su.Gabaɗaya, mafi girman ƙaddamarwar rini da zafin jiki, kuma tsawon lokacin rini, mafi girman yiwuwar haɓakawa da coke.Rini auxiliaries kamar masu dako da matakan daidaitawa na iya maye gurbin tarwatsawar da aka haɗe a cikin rini cikin sauƙi, ta haka rage tarwatsawar kwanciyar hankali.
