Maitiro ekushandisa hydroxyethyl cellulose mupendi yelatex
1. Hydroxyethyl cellulose inoshandiswa kugadzira porridge: Sezvo hydroxyethyl cellulose isiri nyore kunyungudika mu organic solvents, mamwe organic solvents anogona kushandiswa kugadzira porridge. Mvura yechando hainawo solvent yakanaka, saka mvura yechando inowanzo shandiswa pamwe chete ne organic liquids kugadzira porridge. Porridge-like hydroxyethyl cellulose inogona kuwedzerwa zvakananga ku latex pendi. Hydroxyethyl cellulose yakanyikwa zvizere muporridge. Kana yawedzerwa papendi, inonyungudika nekukurumidza uye inoshanda se thickener. Mushure mekuwedzera, ramba uchikurunga kusvika hydroxyethyl cellulose yapararira zvachose uye yanyungudika. Kazhinji, porridge inogadzirwa nekusanganisa zvikamu zvitanhatu zve organic solvent kana ice water nechikamu chimwe che hydroxyethyl cellulose. Mushure memaminitsi angangoita 5-30, hydroxyethyl cellulose inozonyungudika uye inozvimba zviri pachena. (Yeuchidza kuti hunyoro hwemvura yakajairika hwakanyanya muzhizha, saka haifanirwe kushandiswa kugadzira porridge.)
2. Wedzera hydroxyethyl cellulose zvakananga paunenge uchikuya pigment: Nzira iyi iri nyore uye inotora nguva pfupi. Nzira yakadzama ndeiyi inotevera:
(1) Wedzera huwandu hwakakodzera hwemvura yakacheneswa mubhaketi hombe remuchina wekusanganisa simbi (kazhinji, zvinhu zvinobatsira kugadzira firimu uye zvinhu zvinonyorovesa zvinowedzerwa panguva ino)
(2) Tanga kukurunga nguva dzose nekumhanya kwakaderera uye zvishoma nezvishoma uye zvakaenzana wedzera hydroxyethyl cellulose
(3) Ramba uchikurunga kusvika zvidimbu zvese zvapararira zvakaenzana uye zvanyorova
(4) Wedzera zvimwe zvinodzivirira ganda kuti ugadzirise kukosha kwePH
(5) Kurunga kusvika hydroxyethyl cellulose yese yanyungudika zvachose (kunaka kwemushonga kunowedzera zvakanyanya), wobva wawedzera zvimwe zvinhu mufomura, wobva wakuya kusvika pendi yagadzirwa.
3. Gadzirira hydroxyethyl cellulose ne mother liquor kuti uzoshandisa gare gare: Nzira iyi ndeyekugadzirira mother liquor ine huwandu hwakanyanya kutanga, wozoiisa mu latex pendi. Chakanakira nzira iyi ndechekuti inochinjika uye inogona kuwedzerwa zvakananga papendi yapera, asi inofanira kuchengetwa zvakanaka. . Matanho nenzira iyi akafanana nematanho (1)-(4) ari munzira yechipiri, musiyano ndewekuti hapana agitator ine shear high-shear inodiwa, uye mamwe agitators ane simba rakakwana rekuchengetedza hydroxyethyl fiber yakapararira zvakaenzana mumushonga ndiwo Can. Ramba uchikurunga nguva dzose kusvika yanyungudika zvachose kuita viscous solution. Zvinofanira kucherechedzwa kuti mushonga we fungal unofanirwa kuwedzerwa mu paint mother liquor nekukurumidza sezvinobvira.
Zvinhu zvina zvinoda kutariswa pakugadzira hydroxyethyl cellulose mother liquor
Sezvo hydroxyethyl cellulose iri upfu hwakagadziriswa, zviri nyore kubata nekunyungudutsa mumvura chero bedzi zvinhu zvinotevera zvichinyatso tariswa.
(1) Usati waisa hydroxyethyl cellulose uye mushure mekuwedzera, inofanira kumutswa nguva dzose kusvika mhinduro yacho yanyatsojeka uye yakajeka.
(2) Inofanira kupetwa zvishoma nezvishoma mutangi rekusanganisa, uye usawedzera zvakananga huwandu hwakawanda hwehydroxyethyl cellulose hwakaita mapundu kana mabhora mutangi rekusanganisa.
(3) Tembiricha yemvura uye pH iri mumvura zvine hukama hwakakosha nekunyungudika kwehydroxyethyl cellulose, saka kutarisisa kwakakosha kunofanira kupihwa.
(4) Usawedzera zvimwe zvinhu zvine alkaline mumusanganiswa usati wanyikwa upfu hwe hydroxyethyl cellulose nemvura. Kuwedzera pH mushure mekunyorovesa kunobatsira kunyungudika.
(5) Nepose pazvinogoneka, wedzera mushonga unodzivirira fungus nekukurumidza.
(6) Pakushandisa high-viscosity hydroxyethyl cellulose, huwandu hwedoro remubereko haufanirwe kupfuura 2.5-3% (nehuremu), zvikasadaro doro remubereko richava rakaoma kubata.
Zvinhu zvinokanganisa viscosity yependi yelatex:
(1) Nekuda kwekukurunga zvakanyanya, hunyoro hunodziya zvakanyanya panguva yekupararira.
(2) Huwandu hwezvimwe zvinhu zvinosimbisa pendi zvakasikwa uye chiyero chehuwandu hwehydroxyethyl cellulose.
(3) Kana huwandu hwesurfactant nehuwandu hwemvura inoshandiswa mupendi hwakakodzera.
(4) Pakugadzira latex, huwandu hwe oxide hwakaita se catalyst inosara hunoonekwa.
(5) Kuora kwechinhu chinogokora netupukanana.
(6) Mukugadzira pendi, kana matanho ekuwedzera thickener akakodzera.
7 Kana mabhubhu emhepo akawanda achiramba ari mupendi, viscosity inowedzera
