Nzira yekushandisa yehydroxyethyl cellulose mu latex pendi
1. Hydroxyethyl cellulose ine porridge yakafanana nephenology: nokuti hydroxyethyl cellulose haisi nyore kunyungudutswa mune zvinonyungudutsa zvinokonzerwa nehupenyu, mamwe organic solvents anogona kushandiswa kugadzira porridge.Mvura yechando zvakare inonyungudutsa yakaipa, saka inowanzoshandiswa muporridge ine organic liquids.Iyo hydroxyethyl cellulose ye congee fomu inogona kuwedzerwa zvakananga mu emulsii pendi.Hydroxyethyl cellulose yakazadzwa mune porridge fomu.Kana yawedzerwa kupende, inokurumidza kunyungudika uye inowedzera.Ramba uchikurudzira kusvika hydroxyethyl cellulose yaparadzirwa zvachose uye yakanyungudika.Porridge yakajairika inogadzirwa nekusanganisa zvikamu zvitanhatu zveorganic solvent kana ice water nechikamu chimwe chehydroxyethyl cellulose.Mushure memaminitsi mashanu kusvika makumi matatu, iyo hydroxyethyl cellulose ino hydrolyze uye inosimuka zvinooneka.(Zvinonzi hunyoro hwemvura muzhizha hwakanyanya kukwira kuti usashandise porridge.)
2. Wedzera hydroxyethyl cellulose zvakananga kune pigment yekukuya: iyi nzira iri nyore uye nguva ipfupi.Detailed nzira ndedzinotevera:
(1) Wedzera yakakodzera mvura yakachena muVAT yepamusoro inofanirwa kucheka agitator (kazhinji, firimu kugadzira additives uye wetting agents anowedzerwa panguva ino)
(2) Tanga kubvongodza nekumhanya kwakaderera pasina kumira uye zvishoma nezvishoma wowedzera hydroxyethyl cellulose zvakaenzana
(3) Ramba uchikurunga kusvikira zvidimbu zvose zvapararira uye zvanyorova
(4) Wedzera mildew inhibitor uye gadzirisa PH kukosha
(5) Shingairira kusvikira yose hydroxyethyl cellulose yakanyungudutswa zvachose (iyo viscosity yemhinduro inowedzera zvakanyanya), wobva wawedzera zvimwe zvikamu mufomu, uye kugaya kusvikira yava pende.
3 iyo hydroxyethyl cellulose naamai mvura yakamirira: nzira iyi inotanga yakashongedzerwa nehuwandu hwepamusoro hwemvura yaamai, uye wobva wawedzera pendi yelatex, iyo yakanakira nzira iyi inoshanduka, inogona kuwedzera zvakananga pendi yakapedzwa zvigadzirwa, asi kune yakakodzera kuchengetedza.Matanho uye nzira dzakafanana nematanho (1) - (4) muMethod 2, kunze kwekuti agitator yakakwirira yekucheka haidiwi uye mamwe chete aggers ane simba rakakwana kuchengetedza hydroxyethyl fibers yakapararira mumhinduro inoshandiswa.Ramba uchikurunga kusvika yanyungudika zvachose kuita mushonga wakakora.Cherechedza kuti: antimildew agent inofanira kuwedzerwa nokukurumidza sezvinobvira mudoro raamai repende.
4 Nyaya dzinoda kutariswa paunenge uchishongedza hydroxyethyl cellulose mai doro
Sezvo hydroxyethyl cellulose iri yakarapwa granular poda, zviri nyore kubata uye kunyungudika mumvura nedziviriro dzinotevera.
(1) Pamberi uye mushure mekuwedzera hydroxyethyl cellulose, inofanira kuramba ichikurudzira, kusvikira mhinduro yacho yakanyatsojeka uye yakajeka.
(2) Izvo zvinodiwa kusefa iyo hydroxyethyl cellulose mutangi inomutsa zvishoma nezvishoma.Usawedzera muhuwandu hukuru kana zvakananga mutangi rinokurudzira.
(3) Kunyungudika kwehydroxyethyl cellulose zviri pachena kuti kune hukama nekupisa kwemvura uye pH kukosha kwemvura, saka kutarisisa kwakanyanya kunofanirwa kubhadharwa kwairi.
(4) Usawedzera zvimwe zvinhu zvakakosha kumusanganiswa usati wanyikwa hydroxyethyl cellulose poda nemvura.Kusimudza pH mushure mekunyura kunobatsira kunyungudika.
(5) Sezvinobvira, kuwedzera kwekutanga kwe mildew inhibitor.
(6) Paunenge uchishandisa high viscosity hydroxyethyl cellulose, kuwanda kwedoro raamai hakufaniri kunge kwakakwirira kudarika 2.5-3% (kuburikidza nehuremu), zvikasadaro doro raamai rakaoma kushanda.
Zvinhu zvinokanganisa viscosity yepende ye latex:
(1) Nekuda kwekukandira kwakanyanya uye hunyoro hwakanyanya kana uchipararira.
(2) huwandu hwemamwe masikirwo akakora mufomula yepende uye chikamu chehuwandu nehydroxyethyl cellulose.)
(3) huwandu hwepamusoro activator uye mvura mune fomula yepende inowirirana.
(4 mukugadzirwa kwe latex, yasara inokonzeresa oxide yehuwandu hwenhamba.
Microbial erosion ye thickener.
6 mukugadzira pende, kurongeka kwematanho ekuwedzera thickener kwakakodzera.
Iyo yakanyanya kusara mabhubhu emhepo mupende, iyo inowedzera viscosity
