Bayan polymerization, latex yana samun daidaito ta hanyar ƙara ƙwayoyin kariya da masu daidaita sinadarai. Wannan matakin yana hana coagulation na barbashi kuma yana tabbatar da daidaiton wargajewar latex. Ana iya gabatar da magungunan coagulation don haifar da coagulation mai sarrafawa na barbashi na latex, wanda ke samar da coagulum mai karko.
Busar da feshi:
Sannan a zuba ruwan da aka tabbatar da cewa yana da ƙarfi a cikin na'urar busar da iska. A cikin ɗakin busar da iskar, ana ƙara yawan ruwan zuwa ƙananan ɗigon ruwa ta amfani da bututun ƙarfe masu ƙarfi. Ana shigar da iska mai zafi a lokaci guda don ƙafe ruwan da ke cikinsa, yana barin ƙwayoyin polymer masu ƙarfi.
