Yadda ake amfani da hydroxyethyl cellulose a cikin fenti na latex
1. Ana amfani da hydroxyethyl cellulose don shirya porridge: Tun da hydroxyethyl cellulose ba shi da sauƙi a narke a cikin abubuwan da ake amfani da su na kwayoyin halitta, ana iya amfani da wasu kaushi na halitta don shirya porridge. Ruwan kankara shima rashin ƙarfi ne, don haka ana amfani da ruwan ƙanƙara tare da ruwa mai laushi don shirya porridge. Ana iya ƙara porridge-kamar hydroxyethyl cellulose kai tsaye zuwa fenti na latex. Hydroxyethyl cellulose ya kumbura sosai a cikin tanda. Lokacin da aka ƙara zuwa fenti, yana narkewa da sauri kuma yana taka rawa mai kauri. Bayan ƙarawa, har yanzu yana da mahimmanci don ci gaba da motsawa har sai hydroxyethyl cellulose ya tarwatse kuma ya narkar da shi. Gabaɗaya, ana haɗe porridge tare da sassa shida na kaushi na halitta ko ruwan kankara da wani ɓangare na hydroxyethyl cellulose. Bayan kamar minti 5-30, hydroxyethyl cellulose zai zama hydrolyzed kuma ya kumbura a fili. (An ba da shawarar cewa zafi na ruwa na gabaɗaya ya yi yawa a lokacin rani, don haka bai dace a yi amfani da shi ba.)
2. Ƙara hydroxyethyl cellulose kai tsaye lokacin da ake nika pigment: Wannan hanya mai sauƙi ce kuma tana ɗaukar lokaci kaɗan. Hanyar dalla-dalla ita ce kamar haka:
(1) Ƙara ruwa mai tsafta da ya dace a cikin bututun babban mai tayar da hankali (gabaɗaya, ana ƙara kayan aikin fim da masu jika a wannan lokacin)
(2) Fara motsawa akai-akai a ƙananan gudu kuma a hankali kuma a hankali ƙara hydroxyethyl cellulose
(3) Ci gaba da motsawa har sai dukkanin barbashi sun watse sosai kuma a jika
(4) Ƙara abubuwan da ake ƙara antifungal don daidaita ƙimar PH
(5) Har sai duk hydroxyethyl cellulose ya narke gaba daya (dankin maganin yana ƙaruwa sosai), sannan a ƙara wasu abubuwan da ke cikin dabarar, a niƙa har sai ya zama fenti.
3. Shirya hydroxyethyl cellulose tare da mahaifiyar barasa don amfani: Wannan hanyar ita ce a fara shirya giya mai yawa tare da maida hankali sosai, sa'an nan kuma 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 yana buƙatar adana shi da kyau. . Matakan da hanyoyin sun yi kama da matakai (1) - (4) a cikin hanyar 2, bambancin shine cewa babu buƙatar babban mai tayar da hankali, kuma kawai wasu masu tayar da hankali waɗanda ke da isasshen iko don kiyaye filaye na hydroxyethyl daidai tarwatsa a cikin ana amfani da mafita. 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 sauƙi don rikewa da narke cikin ruwa idan dai an lura da waɗannan al'amura.
(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 nitse a cikin ganga mai gauraya sannu a hankali. Kada kai tsaye ƙara hydroxyethyl cellulose wanda aka kafa zuwa dunƙule da ƙwallaye a cikin ganga mai gauraya da yawa ko kai tsaye.
(3) Zazzabi na ruwa da ƙimar pH a cikin ruwa suna da alaƙa mai mahimmanci ga rushewar hydroxyethyl cellulose, don haka ya kamata a biya kulawa ta musamman.
(4) Kada a ƙara wasu abubuwa na alkaline a cikin cakuda kafin a jika foda hydroxyethyl cellulose da ruwa. Kiwon pH kawai bayan jika zai taimaka a rushe.
(5) Kamar yadda zai yiwu, ƙara wakili na antifungal da wuri-wuri.
(6) Lokacin amfani da high-viscosity hydroxyethyl cellulose, maida hankali na uwa barasa kada ya zama sama da 2.5-3% (ta nauyi), in ba haka ba uwar barasa zai yi wuya a rike.
Abubuwan da ke shafar dankowar fenti na latex:
(1) Zafin ya yi zafi sosai yayin watsawa saboda yawan motsawa.
(2) Matsakaicin adadin sauran masu kauri na halitta da adadin adadin hydroxyethyl cellulose a cikin dabarar fenti. )
(3) Ko adadin surfactant da adadin ruwa a cikin dabarar fenti sun dace.
(4 Lokacin hada latex, adadin saura mai kara kuzari da sauran oxides.
5 Yashwar ƙananan ƙwayoyin cuta na thickeners.
6 Yayin aiwatar da aikin fenti, shin jerin matakai don ƙara masu kauri sun dace?
