Hydroxyethyl Cellulose (HEC) Iine mabasa akawanda, anosanganisira: kukora, kumisa, kusunga, emulsifying, firimu-kuumba, kugadzikana, kuparadzira, kuchengetedza mvura, nekugadzira macolloid ekudzivirira.Iyo yakanyanya kunyungudika mumvura inopisa kana inotonhora, inogona kugadzirwa kuita mhinduro mune dzakasiyana siyana viscosities, uye ine yakanakisa kuramba kune yakanyungudika electrolytes.

Wedzera zvakananga paunenge uchikuya pigment:
1. Wedzera mvura yakakodzera yakanatswa kubhakiti guru rakagadzirirwa ne-high-cut agitator (kazhinji, ethylene glycol, wetting agent uye firimu-forming agent inowedzerwa mune iyi danho).
2. Tanga kubvongodza uchienderera mberi nekumhanya kwakaderera uye zvishoma nezvishoma sieve hydroxyethyl cellulose zvakaenzana mumhinduro.
3. Ramba uchikurunga kusvika zvidimbu zvese zvanyorova.
4. Zvadaro wedzera antifungal agent, alkaline additives yakadai se pigment dispersing aids, ammonia mvura.
5. Kurudzira kusvikira yose hydroxyethyl cellulose yakanyungudutswa zvachose (iyo viscosity yemhinduro inowedzera zvakanyanya) isati yawedzera zvimwe zvikamu mufomu, uye kugaya kusvikira yava pende.

Yakashongedzerwa nedoro raamai rekushandisa:
Iyi nzira ndeyekutanga kugadzirira amai doro rine huwandu hwepamusoro, uye wozowedzera kune latex pendi.Kubatsira kweiyi nzira ndeyokuti ine hukuru hunochinja uye inogona kuwedzerwa zvakananga kupende yakapedzwa, asi kuchengetedza kwakakodzera kunodiwa.Matanho acho akafanana nematanho 1-4 mune nzira (1), mutsauko ndewekuti hapana chikonzero che-high-shear agitator, uye chete mamwe agitators ane simba rakakwana kuchengetedza hydroxyethyl cellulose yakapararira mumhinduro inogona kushandiswa. .Ramba uchikurudzira kusvikira yanyungudika zvachose muine viscous solution.Izvo zvinofanirwa kucherechedzwa kuti iyo antifungal agent inofanirwa kuwedzerwa kuna amai doro nekukurumidza.

Kune porridge-senge phenology:
Sezvo organic zvinonyungudutsa zvisingaite zvinonyungudutsa zvehydroxyethyl cellulose, izvi organic solvents zvinogona kushandiswa kugadzira porridge.Zvinonyanya kushandiswa organic zvinonyungudutsa zvinwiwa organic senge ethylene glycol, propylene glycol, uye mafirimu ekare (eg, hexanediol kana Butyl CARBITOL acetate) mukugadzira pendi.Mvura yeaizi zvakare haina kunyungudika, saka mvura yechando inowanzoshandiswa neorganic liquid kugadzira porridge.
Iyo porridge-senge hydroxyethyl cellulose inogona kuwedzerwa zvakananga kupende.Iyo hydroxyethyl cellulose yakazvimba zvakakwana mu porridge state.Kana yawedzerwa papende, inonyungudika pakarepo uye inowedzera.Mushure mekuwedzera, zvichiri kudikanwa kuti urambe uchikurudzira kusvika iyo hydroxyethyl cellulose yanyungudika zvachose uye yunifomu.
Kazhinji, porridge inosanganiswa nezvikamu zvitanhatu zveorganic solvent kana ice water uye chikamu chimwe chehydroxyethyl cellulose.Mushure memaminitsi angangoita 5-30, iyo hydroxyethyl cellulose ichave hydrolyzed uye kuzvimba zviri pachena.Muzhizha, kutonhora kwemvura kwakanyanyisa, uye hazvina kukodzera porridge.
Nyaya dzinoda kutariswa paunenge uchigadzira hydroxyethyl cellulose mai doro:
Hydroxyethyl cellulose kazhinji ihupfu yakagadziriswa uye granular zvinhu.Chero bedzi zvinhu zvinotevera zvichionekwa, zviri nyore kubata uye kunyungudutswa mumvura.
1. Usati wawedzera uye mushure mekuwedzera hydroxyethyl cellulose, ramba uchikurudzira kusvikira mhinduro yacho yakanyatsojeka uye yakajeka.
2. Inofanira kupepetwa muhari yekuvhenganisa zvishoma nezvishoma.Usawedzera zvakananga iyo hydroxyethyl cellulose iyo yakaumbwa kuita mapundu kana mabhora mugomba rekusanganisa.
3. Kupisa kwemvura uye pH kukosha kwemvura kune hukama huri pachena nekuparara kwehydroxyethyl cellulose, saka kunyanya kunofanira kubhadharwa kwairi.
4. Usambofa wakaisa zvimwe zvinhu zvealkaline kumusanganiswa usati wanyikwa hydroxyethyl cellulose poda nemvura.Kusimudza pH chete mushure mekunyorova kunobatsira mukuparara.
5. Sezvinobvira, wedzera antifungal agent nekukurumidza sezvinobvira.
6. Paunenge uchishandisa high-viscosity hydroxyethyl cellulose, kusanganiswa kwedoro raamai hakufaniri kunge kwakakwirira kudarika 2.5-3% (kuburikidza nekurema), kana zvisina kudaro amai doro richava rakaoma kubata.
