Pendi giredhi HEC

Paint giredhi HEC Hydroxyethyl cellulose imhando yepolymer isiri-ionic mvura-inonyungudika, chena kana yero, iri nyore kuyerera, isinganhuhwi uye isinganakidze, inogona kunyungudika mumvura inotonhora uye inopisa, uye mwero wekunyungudika unowedzera nekupisa, kazhinji isinganyungudika mukati. yakawanda organic solvents.Iyo ine yakanaka PH kugadzikana uye zvishoma viscosity shanduko muhuwandu hweph2-12.HEC ine yakakwirira munyu kuramba uye hygroscopic kugona, uye ine yakasimba hydrophilic mvura kuchengetedza.Mhinduro yayo ine aqueous ine pamusoro pekuita uye yakakwirira viscosity zvigadzirwa zvine yakakwira pseudoplasticity.Inogona kugadzirwa kuita anhydrous transparent film ine simba riri pakati nepakati, isingatapurwe nyore neoiri, isina kukanganiswa nechiedza, ichine HEC inonyungudika mvura firimu.Mushure mekurapa kwepamusoro, HEC inopararira uye haina kubatana mumvura, asi inopera zvishoma nezvishoma.Iyo PH inogona kugadziriswa ku8-10 uye nekukurumidza kunyungudika.

Zvinhu zvikuru

Hydroxyethyl cellulose (HEC) ndeyekuti inogona kunyungudutswa mumvura inotonhora nemvura inopisa, uye haina gel maitiro.Iine huwandu hwakawanda hwekutsiva, solubility uye viscosity.Iine kugadzikana kwakanaka kwekushisa (pasi pe140 ° C) uye haibereki pasi pemamiriro e acidic.kunaya kwemvura.Iyo hydroxyethyl cellulose (HEC) mhinduro inogona kuumba firimu rakajeka, iro riine asiri-ionic maficha asingadyidzane nemaion uye ane kuenderana kwakanaka.

Sechidziviriro colloid, Paint giredhi HEC inogona kushandiswa vinyl acetate emulsion polymerization kuvandudza kugadzikana kwepolymerization system mune yakakura PH renji.Mukugadzira zvigadzirwa zvakapedzwa kugadzira pigment, filler uye zvimwe zvinowedzera zvakapararira zvakapararira, zvakagadzikana uye zvinopa thickening maitiro.Inogona zvakare kushandiswa kune styrene, acrylic, acrylic uye mamwe akamiswa mapolymers seanoparadzira, anoshandiswa mupende yelatex anogona kuvandudza zvakanyanya kukora, kuvandudza mashandiro ekuita.

Nzira yekushandisa hydroxyethyl cellulose HEC mumvurapendi

1. Wedzera zvakananga paunenge uchikuya pigment: iyi nzira ndiyo iri nyore, uye nguva inoshandiswa ipfupi.Matanho akadzama ndeaya:

(1) Wedzera mvura yakacheneswa yakakodzera muVAT yeagitator yakakwira (kazhinji, ethylene glycol, wetting agent uye mugadziri wekugadzira firimu anowedzerwa panguva ino)

(2) Tanga kubvongodza nekumhanya kwakaderera uye zvishoma nezvishoma wedzera hydroxyethyl cellulose

(3) Ramba uchikurunga kusvikira zvidimbu zvose zvanyorova

(4) wedzera mildew inhibitor, PH regulator, nezvimwe

(5) Shingairira kusvikira yose hydroxyethyl cellulose yakanyungudutswa zvachose (iyo viscosity yemhinduro inowedzera zvakanyanya) isati yawedzera zvimwe zvikamu mufomu, uye kugaya kusvikira yava pende.

2. yakashongedzerwa nemvura yaamai yakamirira: nzira iyi inotanga yakashongedzerwa nehuwandu hwepamusoro hwemvura yaamai, uye wobva wawedzera pendi yelatex, mukana weiyi nzira yakanyanya kushanduka, inogona kuwedzerwa zvakananga kupendeka zvigadzirwa, asi inofanira kuva yakakodzera kuchengetedza. .Matanho uye nzira dzakafanana nematanho (1) - (4) muMethod 1, kunze kwekuti agitator yakakwirira yekucheka haidiwi uye chete imwe agitator ine simba rakakwana kuchengetedza hydroxyethyl fibers yakapararira mumhinduro yakakwana.Ramba uchikurunga kusvika yanyungudika zvachose kuita mushonga wakakora.Ziva kuti mildew inhibitor inofanira kuwedzerwa kudoro raamai nekukasika.

3. Porridge yakafanana nephenology: Sezvo organic solvents ari akaipa zvinonyungudutsa zvehydroxyethyl cellulose, izvi organic solvents zvinogona akashongedzerwa porridge.Iyo inonyanya kushandiswa organic solvents senge ethylene glycol, propylene glycol, uye firimu kugadzira agents (senge hexadecanol kana diethylene glycol butyl acetate), mvura yechando zvakare inonyungudutsa isina kunaka, saka mvura yechando inowanzoshandiswa nezvinwiwa organic mu porridge.Gruel - senge hydroxyethyl cellulose inogona kuwedzerwa zvakananga kupende.Hydroxyethyl cellulose yakazadzwa mune porridge fomu.Mushure mekuwedzera lacquer, nyungudika nekukurumidza uye uve nekuita thickening.Mushure mekuwedzera, ramba uchikurudzira kusvika hydroxyethyl cellulose yanyungudika zvachose uye yunifomu.Porridge yakajairika inogadzirwa nekusanganisa zvikamu zvitanhatu zveorganic solvent kana ice water nechikamu chimwe chehydroxyethyl cellulose.Mushure memaminitsi anenge 5-30, iyo Paint giredhi HEC hydrolyzes uye inooneka inosimuka.Muchirimo, mwando wemvura wakanyanya kukwirisa kuti usashandise porridge.

4 .Nyaya dzinoda kutariswa paunenge uchigadzira doro raamai rehydroxyethyl cellulose:

Pchenjedzo

1 Pamberi uye mushure mekuwedzera Paint giredhi HEC, inofanira kusimudzwa nguva dzose kusvikira mhinduro yacho yakanyatsojeka uye yakajeka.

2. Sefa iyo hydroxyethyl cellulose mutangi yekusanganisa zvishoma nezvishoma.Usaiwedzere mutangi rekusanganisa muhuwandu hukuru kana zvakananga muhuwandu kana spherical Paint giredhi HEC.

3 tembiricha yemvura uye pH kukosha kwemvura zvine hukama huri pachena nekuparara kwePaint giredhi HEC hydroxyethyl cellulose, saka kutarisisa kwakanyanya kunofanirwa kubhadharwa kwairi.

Usawedzera chimwe chinhu chakakosha kumusanganiswa pamberi pePaint giredhi HEC hydroxyethyl cellulose poda yakanyikwa nemvura.Kusimudza pH mushure mekunyura kunobatsira kunyungudika.

5 .Sezvinobvira, kuwedzera kwekutanga kwe mildew inhibitor.

6 Paunenge uchishandisa high viscosity Paint giredhi HEC, kuwanda kwedoro raamai hakufanirwe kunge kwakakwira kupfuura 2.5-3% (kuburikidza nehuremu), kana zvisina kudaro mai doro rakaoma kushanda.

Zvinhu zvinokanganisa viscosity yepende ye latex

1.Kunyanya kusara kwemhepo inoputika mupende, iyo inowedzera viscosity.

2.Iyo huwandu hwe activator uye mvura mupendi formula inowirirana here?

3 mukugadzirwa kwelatex, yakasara inokonzeresa oxide yehuwandu hwehuwandu.

4. Kuyerwa kwemamwe masikirwo akakora mufomula yependi uye chiyero chepimo nePaint giredhi HEC.)

5.mukuita pende, kurongeka kwematanho ekuwedzera thickener kwakakodzera.

6.Nekuda kwekunyanya kunetseka uye kunyorova kwakanyanya panguva yekupararira.

7.Microbial erosion of thickener.
