Hydroxyethyl Cellulose (HEC) Ili ndi ntchito zambiri, kuphatikizapo: kukhuthala, kuyimitsa, kumanga, kutsekemera, kupanga mafilimu, kukhazikika, kufalitsa, kusunga madzi, ndi kupanga colloids zoteteza. Ndiwosungunuka kwambiri m'madzi otentha kapena ozizira, amatha kupangidwa kukhala njira zothetsera ma viscosities osiyanasiyana, ndipo amatha kukana kwambiri ma electrolyte osungunuka.
njira imodzi)
Onjezani mwachindunji pogaya pigment:
1. Onjezerani madzi oyeretsedwa oyenerera ku chidebe chachikulu chokhala ndi agitator odulidwa kwambiri (kawirikawiri, ethylene glycol, wetting agent ndi filimu yopangira mafilimu akuwonjezeredwa mu sitepe iyi).
2. Yambani kuyambitsa mosalekeza pa liwiro lotsika ndikusefa pang'onopang'ono hydroxyethyl cellulose mu njira yothetsera.
3. Pitirizani kuyambitsa mpaka tinthu tating'onoting'ono tanyowa.
4. Kenaka yikani antifungal wothandizira, zowonjezera zamchere monga pigment dispersing aids, ammonia madzi.
5. Onetsetsani mpaka cellulose yonse ya hydroxyethyl itasungunuka kwathunthu (kukhuthala kwa yankho kumawonjezeka kwambiri) musanawonjezere zigawo zina mu chilinganizo, ndikupera mpaka utoto.

Zokhala ndi mowa wamayi kuti mugwiritse ntchito:
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 kusungirako koyenera kumafunika. Masitepewo ndi ofanana ndi masitepe 1-4 mu njira (1), kusiyana kwake ndikuti palibe chifukwa chothamangitsira kumeta ubweya wambiri, ndipo ma agitators ena okha omwe ali ndi mphamvu zokwanira kusunga cellulose ya hydroxyethyl mofanana omwazika mu yankho angagwiritsidwe ntchito. . Pitirizani kusonkhezera mpaka kusungunuka kwathunthu mu viscous solution. Tiyenera kuzindikira kuti antifungal wothandizira ayenera kuwonjezeredwa kwa mowa wa amayi mwamsanga.

Kwa phenology ngati phala:
Popeza zosungunulira organic ndi osauka solvents kwa hydroxyethyl mapadi, izi zosungunulira organic angagwiritsidwe ntchito pokonzekera phala. Zosungunulira zomwe zimagwiritsidwa ntchito kwambiri ndi zamadzimadzi monga ethylene glycol, propylene glycol, ndi zopangira mafilimu (monga hexanediol kapena Butyl CARBITOL acetate) popanga utoto. Madzi a ayezi nawonso sasungunuka bwino, choncho madzi a ayezi nthawi zambiri amagwiritsidwa ntchito ndi zakumwa za organic pokonzekera phala.
Phala-ngati hydroxyethyl cellulose akhoza kuwonjezeredwa mwachindunji ku utoto. The hydroxyethyl cellulose wakhala mokwanira kutupa mu phala boma. Akawonjezeredwa ku utoto, amasungunuka nthawi yomweyo ndikukhuthala. Pambuyo powonjezera, m'pofunikabe kusonkhezera mpaka hydroxyethyl cellulose itasungunuka kwathunthu ndi yunifolomu.
Nthawi zambiri, phala limasakanizidwa ndi magawo asanu ndi limodzi a organic zosungunulira kapena madzi a ayezi ndi gawo limodzi la hydroxyethyl cellulose. Pambuyo pa mphindi 5-30, cellulose ya hydroxyethyl imapangidwa ndi hydrolyzed ndikutupa mwachiwonekere. M'chilimwe, kutentha kwa madzi kumakhala kwakukulu, ndipo sikuli koyenera phala.
Mfundo zofunika kuziganizira pokonza mowa wa hydroxyethyl cellulose:
Hydroxyethyl cellulose nthawi zambiri ndi ufa wopangidwa ndi granular. Malingana ngati zinthu zotsatirazi zikudziwika, ndizosavuta kuzigwira ndikusungunuka m'madzi.
1. Musanayambe kapena mutatha kuwonjezera hydroxyethyl cellulose, pitirizani kuyambitsa mpaka yankho likuwonekera bwino komanso lomveka bwino.
2. Iyenera kusefedwa mu mbiya yosakaniza pang'onopang'ono. Osawonjezera mwachindunji cellulose ya hydroxyethyl yomwe idapangidwa kukhala zotupa kapena mipira mu mbiya yosakaniza.
3. Kutentha kwa madzi ndi pH mtengo wa madzi ali ndi ubale woonekeratu ndi kusungunuka kwa hydroxyethyl cellulose, kotero chidwi chapadera chiyenera kuperekedwa kwa izo.
4. Musawonjezere zinthu za alkaline kusakaniza ufa wa hydroxyethyl cellulose usanavidwe ndi madzi. Kukweza pH pokhapokha kunyowetsa kumathandizira kusungunuka.
5. Momwe mungathere, onjezerani antifungal wothandizira mwamsanga.
6. Mukamagwiritsa ntchito high-viscosity hydroxyethyl cellulose, kuchuluka kwa mowa wa mayi sayenera kupitirira 2.5-3% (ndi kulemera kwake), apo ayi mowa wa amayi udzakhala wovuta kupirira.
