Pendi giredhi HEC

Pendi giredhiHEC Hydroxyethyl cellulose imhando yepolymer isiri-ionic mvura-inonyungudika, chena kana yero, iri nyore kuyerera, isina kunhuwa uye isinganakidze, inogona kunyungudika mumvura inotonhora uye inopisa, uye chiyero chekunyungudika chinowedzera nekupisa, kazhinji kusanyungudika mune zvakawanda organic. solvents. Iyo ine yakanaka PH kugadzikana uye zvishoma viscosity shanduko muhuwandu hweph2-12. HEC ine yakakwira 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)ndezvekuti 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 senge phenology: Sezvo organic solvents ari akaipa zvinonyungudutsa zvehydroxyethyl cellulose, izvi organic zvinonyungudutsa zvinogona kugadzirwa 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 kusvikira hydroxyethyl cellulose yanyungudutswa zvachose uye yunifomu. Porridge yakajairika inogadzirwa nekusanganisa zvikamu zvitanhatu zveorganic solvent kana ice water nechikamu chimwe chehydroxyethyl cellulose. Mushure memaminitsi 5-30, iyo Paint giredhiHEChydrolyzes uye inooneka inosimuka. Muchirimo, hunyoro hwemvura hwakanyanya kukwira kuti usashandise porridge.

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

Pchenjedzo

1 Pamberi uye mushure mekuwedzera Paint giredhiHEC, inofanira kukurudzirwa nguva dzose kusvikira mhinduro yacho yakanyatsojeka uye yakajeka.

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

3 tembiricha yemvura uye pH kukosha kwemvura zvine hukama huri pachena nekuparara kwePaint giredhiHEChydroxyethyl cellulose, saka kutarisisa kwakakosha kunofanirwa kubhadharwa kwairi.

Usawedzera chimwe chinhu chakakosha kumusanganiswa pamberi pegiredhi rePaintHEChydroxyethyl cellulose poda yakanyoroveswa nemvura. Kusimudza pH mushure mekunyura kunobatsira kunyungudika.

5 .Sezvinobvira, kuwedzera kwekutanga kwe mildew inhibitor.

6 Paunenge uchishandisa yakakwira viscosity Paint giredhiHEC, kuwanda kwedoro raamai hakufaniri kunge kwakakwirira kudarika 2.5-3% (kuburikidza nekurema), kana zvisina kudaro amai 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. Chiyero chemamwe masikirwo akakora mufomula yependi uye chiyero chedosi 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.
