Momwe mungagwiritsire ntchito hydroxyethyl cellulose

1. Lowani mwachindunji pa nthawi yopanga

1. Onjezerani madzi oyera ku chidebe chachikulu chokhala ndi makina opangira ubweya wambiri.
2. Yambani kuyambitsa mosalekeza pa liwiro lotsika ndikusefa pang'onopang'ono cellulose ya hydroxyethyl mu yankho mofanana.
3. Pitirizani kuyambitsa mpaka tinthu tating'onoting'ono tanyowa.
4. Kenaka yikani antifungal agents, zowonjezera zamchere monga ma pigment, dispersing aids, ammonia madzi.
5. Onetsetsani mpaka cellulose yonse ya hydroxyethyl itasungunuka kwathunthu (kukhuthala kwa yankho kumawonjezeka kwambiri) musanawonjezere zigawo zina mu ndondomeko, ndikupera mpaka mankhwala omalizidwa.

2. Kukhala ndi chakumwa cha mayi podikirira

Njirayi ndiyoyamba kukonzekera chakumwa cha amayi chokhala ndi ndende yapamwamba, ndikuwonjezera pa utoto wa latex.Ubwino wa njirayi ndikuti umakhala ndi kusinthasintha kwakukulu ndipo ukhoza kuwonjezeredwa mwachindunji ku utoto womalizidwa, koma uyenera kusungidwa bwino.Masitepewo ndi ofanana ndi masitepe 1-4 mu njira 1, kupatula kuti kusonkhezera kwakukulu sikofunikira kuti kusungunuke mu njira yothetsera viscous.

3.Kukonzekera phala kuti mugwiritse ntchito

Popeza zosungunulira za organic ndi zosungunulira zosakwanira za hydroxyethyl cellulose, zosungunulira za organic izi zitha kugwiritsidwa ntchito popanga zinthu ngati phala.Zosungunulira zomwe zimagwiritsidwa ntchito kwambiri ndi zinthu zamadzimadzi zomwe zimapangidwira mu utoto monga ethylene glycol, propylene glycol ndi zopangira mafilimu (monga ethylene glycol kapena diethylene glycol butyl acetate).Madzi a ayezi nawonso samasungunuka bwino, kotero madzi a ayezi nthawi zambiri amagwiritsidwa ntchito limodzi ndi zakumwa zamadzimadzi pokonzekera phala ngati phala.Chogulitsa chofanana ndi phala, hydroxyethyl cellulose, chikhoza kuwonjezeredwa mwachindunji ku utoto, ndipo hydroxyethyl cellulose yakhala ikuchita thovu ndikutupa ndi phala.Akawonjezeredwa ku utoto, amasungunuka nthawi yomweyo ndikukhuthala.Pambuyo powonjezera, m'pofunikabe kusonkhezera mpaka hydroxyethyl cellulose itasungunuka kwathunthu ndi yunifolomu.Nthawi zambiri, mankhwala ngati phala amasakanizidwa ndi magawo asanu ndi limodzi a zosungunulira organic kapena madzi a ayezi ndi gawo limodzi la cellulose ya hydroxyethyl.Pambuyo pa mphindi 6-30, cellulose ya hydroxyethyl imapangidwa ndi hydrolyzed ndikutupa mwachiwonekere.M'chilimwe, kutentha kwa madzi kumakhala kokwera kwambiri, ndipo sikoyenera kugwiritsa ntchito zinthu zofanana ndi phala.
