3. Shirya hydroxyethyl cellulose tare da mahaifiyar barasa don amfani da shi daga baya: Wannan hanyar ita ce a fara shirya giya mai yawa tare da maida hankali sosai da farko, sannan a ƙara shi zuwa fenti na latex.Amfanin wannan hanya shine ya fi sauƙi kuma ana iya ƙara shi kai tsaye zuwa fenti da aka gama, amma dole ne a adana shi da kyau..Matakan da hanyar sun yi kama da matakai (1) - (4) a cikin hanyar 2, bambanci shine cewa ba a buƙatar babban mai tayar da hankali ba, kuma kawai wasu masu tayar da hankali waɗanda ke da isasshen iko don kiyaye fiber hydroxyethyl ya tarwatsa daidai a cikin maganin su Can. .Ci gaba da motsawa akai-akai har sai an narkar da shi gaba daya a cikin bayani mai danko.Ya kamata a lura da cewa dole ne a ƙara wakili na antifungal a cikin ruwan innabi mai launi da wuri-wuri.
4 Abubuwan da ke buƙatar kulawa yayin shirya ruwan inabi na hydroxyethyl cellulose
Tun da hydroxyethyl cellulose foda ne da aka sarrafa, yana da sauƙin rikewa da narkar da shi a cikin ruwa muddin ana kula da abubuwa masu zuwa.
(1) Kafin da kuma bayan ƙara hydroxyethyl cellulose, dole ne a ci gaba da motsawa har sai bayani ya zama cikakke kuma bayyananne.
(2) Dole ne a tsoma shi a hankali a cikin tanki mai haɗuwa, kuma kada a ƙara yawan adadin hydroxyethyl cellulose kai tsaye wanda ya kafa dunƙule ko ƙwallo a cikin tanki mai haɗuwa.
(3) Ruwan zafin jiki da darajar pH a cikin ruwa suna da dangantaka mai mahimmanci tare da rushewar hydroxyethyl cellulose, don haka dole ne a biya kulawa ta musamman.
(4) Kada a ƙara wasu abubuwa na alkaline a cikin cakuda kafin a jika foda hydroxyethyl cellulose da ruwa.Haɓaka pH bayan jika yana taimakawa rushewa.
