3. tare da poridge
Tun da kwayoyin halitta shine rashin ƙarfi na hydroxyethyl cellulose, ana iya amfani da waɗannan magungunan kwayoyin don samar da porridge.Abubuwan da aka fi amfani da su kamar su ethylene glycol, propylene glycol, da masu yin fim (kamar hexane ko diethylene glycol butyl acetate), ruwan kankara shima rashin ƙarfi ne, don haka ana amfani da ruwan kankara tare da ruwa mai ƙarfi Ana sanye da shi. poridge.Za a iya ƙara porridge-kamar hydroxyethyl cellulose kai tsaye zuwa fenti.Hydroxyethyl cellulose an jiƙa sosai a cikin porridge.Idan an ƙara shi a fenti, ya narke nan da nan kuma ya yi kauri.Bayan ƙari, ya zama dole a ci gaba da motsawa har sai hydroxyethyl cellulose ya narkar da shi gaba daya kuma yayi kama da juna.Gabaɗaya, porridge yana haɗe da wani yanki na kaushi mai ƙarfi ko ruwan kankara da wani yanki na hydroxyethyl cellulose.Bayan kamar minti 5 zuwa 30, hydroxyethyl cellulose yana yin ruwa kuma yana tashi sosai.Gabaɗaya, zafi na ruwa a lokacin rani ya yi yawa kuma bai kamata a yi amfani da shi don porridge ba.
4. Tsare-tsare yayin amfani da giya na mahaifiyar hydroxyethyl cellulose
Tun da hydroxyethyl cellulose (HEC)shi ne granule da aka kula da shi, yana da sauƙin sarrafawa da narkewa a cikin ruwa idan dai an lura da abubuwa masu zuwa.
(1) Kafin da kuma bayan ƙari na hydroxyethylcellulose, dole ne a ci gaba da motsawa har sai bayani ya bayyana gaba daya kuma ya bayyana.
(2) Dole ne a sanya shi a hankali a cikin tanki mai haɗuwa.Kada a ƙara hydroxyethyl cellulose wanda aka kafa ya zama toshe da siffa mai siffa kai tsaye cikin tanki mai haɗawa.
(3) Ruwan zafin jiki da ƙimar pH a cikin ruwa suna da alaƙa mai mahimmanci tare da rushewar hydroxyethyl cellulose, kuma dole ne a dauki kulawa ta musamman.
(4) Kada a ƙara wasu abubuwa na alkaline zuwa gauraya kafin foda hydroxyethyl cellulose ya jika da ruwa.Ƙara pH bayan jiƙa yana taimakawa wajen narkewa.
