Hydroxyethyl cellulose

Hydroxyethyl cellulose (HEC) ichena kana yakareruka yeyero, isinganhuhwi, isina-chepfu fibrous kana upfu hwakasimba yakagadzirwa ne etherification yealkaline cellulose uye ethylene oxide (kana chlorohydrin). Nonionic soluble cellulose ethers. Nemhaka yokuti HEC ine zvinhu zvakanaka zvekukora, kumisa, kuparadzira, emulsifying, kusungirirwa, kugadzira firimu, kuchengetedza unyoro uye kupa macolloid ekudzivirira, yakashandiswa zvakanyanya mukuongorora kwemafuta, kuvhara, kuvaka, mishonga uye zvokudya, machira, mapepa uye mapolymers. Polymerization uye mamwe minda. Hydroxyethyl cellulose haina kugadzikana pane yakajairika tembiricha uye kumanikidzwa, kudzivirira hunyoro, kupisa, uye tembiricha yepamusoro, uye ine yakasarudzika munyu mukunyungudika kune dielectrics. Mushonga waro wemvura unobvumirwa kuva nehuwandu hwehuwandu hwemunyu uye wakagadzikana.

Mirayiridzo
Join zvakananga mukugadzira

1. Wedzera mvura yakachena kubhakiti guru rakagadzirirwa ne-high-shear blender.

2. Tanga kubvongodza uchienderera mberi nekumhanya kwakaderera uye zvishoma nezvishoma sieve hydroxyethyl cellulose mumugadziro wakaenzana.

3. Ramba uchikurunga kusvika zvidimbu zvese zvanyorova.

4. Zvadaro wobva wawedzera antifungal agents, alkaline additives akadai pigments, kuparadzira rubatsiro, ammonia mvura.

5. Shingairira kusvikira yose hydroxyethyl cellulose yakanyungudutswa zvachose (viscosity yemhinduro inowedzera zvakanyanya) isati yawedzera zvimwe zvikamu muhutano, uye kugaya kusvikira chigadzirwa chapera.

Akashongedzerwa nedoro ramai

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 inofanira kuchengetwa zvakanaka. Matanho acho akafanana nematanho 1-4 mune nzira 1, kunze kwekuti kukwidza kwepamusoro hakudiwi kunyungudika zvachose mumhinduro ye viscous.

Chenjerera
Sezvo iyo yepamusoro-yakagadziriswa hydroxyethyl cellulose ipfu kana cellulose yakasimba, zviri nyore kubata uye kunyungudika mumvura chero bedzi zvinhu zvinotevera zvichionekwa.

1. Pamberi uye mushure mekuwedzera hydroxyethyl cellulose, inofanira kuramba ichikurudzirwa 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 muhuwandu hukuru kana zvakananga.

3. Kupisa kwemvura uye pH kukosha kwemvura kune hukama hunokosha nekuparara kwehydroxyethyl cellulose, saka kunyanya kunofanira kubhadharwa kwairi.

4. Usambofa wakaisa zvimwe zvinhu zvealkaline kumusanganiswa usati hydroxyethyl cellulose poda yadziyirwa nemvura. Kusimudza kukosha kwePH mushure mekudziya kunobatsira pakuparara.

5. Sezvinobvira, wedzera antifungal agent nekukurumidza sezvinobvira.

6. Paunenge uchishandisa high-viscosity hydroxyethyl cellulose, kusanganiswa kwedoro raamai hakufaniri kunge kwakakwirira kudarika 2.5-3%, kana zvisina kudaro amai doro rakaoma kushanda. Iyo post-yakarapwa hydroxyethyl cellulose kazhinji haisi nyore kuumba mapundu kana mativi, uye haizogadziri insoluble spherical colloids mushure mekuwedzera mvura.
