HEC yePaint

HEC ipfupi kune hydroxyethyl Cellulose. Hydroxyethyl celluloseHECichena kana yakachenuruka yero, isinganakidze, isina muchetura, ine fibrous kana upfu hwakasimba yakagadzirwa ne etherification yealkaline cellulose uye ethylene oxide (kana chloroethanol). Iyo isiri-ionic soluble cellulose ether. Senge isiri-ionic surfactant, kunze kwekukora, kumiswa, kusungirirana, kuyangarara, kuumba firimu, kuparadzira, kuchengetedza mvura nekudzivirira.

Chemical features:

1, HEC inogona kunyungudutswa mumvura inopisa kana inotonhora, kupisa kwakanyanya kana kubikira hakuregi, kuitira kuti ive nehupamhi hwekunyungudika uye viscosity properties, uye isiri-thermal gel;

2, iyo isiri-ionic inogona kugarisana nemamwe akawanda-anonyungudika mapolymers, ma surfactants, munyu, yakanakisa colloidal thickener ine high concentration ye electrolyte solution;

3, simba rekuchengetedza mvura rakakwirira zvakapetwa kaviri kupfuura methyl cellulose, ine yakanaka kuyerera inogadziriswa,

4. HEC ine simba rakaipisisa rekupararira kana ichienzaniswa neyakazivikanwa methyl cellulose uye hydroxypropyl methyl cellulose, asi iyo yakasimba kwazvo colloid kudzivirira kugona.

Naizvozvo, hydroxyethyl cellulose inoshandiswa zvakanyanya mu petroleum exploitation, coating, kuvaka, mushonga uye chikafu, machira, kugadzira mapepa uye polymer polymerization reaction uye mamwe minda.

Main zvimiro zveHECnokuda kwepende ye latex

1.Kukora pfuma

Hydroxyethyl cellulose (HEC) ndiyo yakanakira gobvu yekukandira uye zvekuzora. Muchishandiso chinoshanda, kusanganiswa kwekukora kwayo nekumiswa, kuchengetedzwa, kupararira uye kuchengetwa kwemvura kunoburitsa mhedzisiro yakanaka.

1. pseudoplastic

Pseudoplasticity ndiyo pfuma iyo viscosity yemhinduro inodzikira nekuwedzera kwekutenderera kumhanya. HEC ine latex pende iri nyore kushandisa nebrashi kana roller uye inogona kuwedzera kutsetseka kwepamusoro, iyo inogonawo kuwedzera kushanda kwekushanda; Hec-ine shampoos inoyerera uye inonamira, inonyungudika zviri nyore uye inoparadzirwa zviri nyore.

1. Kuramba munyu

HEC yakagadzikana mune yakanyanya kunyura saline mhinduro uye haiparare kuita ionic nyika. Inoshandiswa mu electroplating, inogona kuita kuti plating iwedzere kuzara, kupenya zvakanyanya. Chinonyanya kukosha ndechekushandiswa kwependi yeborate, silicate uye carbonate latex, ichiri neine viscosity yakanaka kwazvo.

4.A membranous

Iyo membrane yekugadzira zvinhu zveHEC inogona kushandiswa mumaindasitiri mazhinji. Mumabasa ekugadzira mapepa, akaputirwa neHEC glazing agent, anogona kudzivirira kupinda kwemafuta, uye anogona kushandiswa kugadzirira zvimwe zvikamu zvekugadzirisa mapepa; HEC inowedzera elasticity yemafibhi panguva yekuruka uye nokudaro inoderedza kukuvadzwa kwemichina kwavari. HEC inoshanda sefirimu yekudzivirira kwenguva pfupi panguva yekuyera uye kudhayira kwejira uye inogona kushambidzwa kubva pamucheka nemvura kana kudzivirira kwayo kusingadiwi.

1. Kuchengetedza mvura

HEC inobatsira kuchengetedza hunyoro hwehurongwa huri munzvimbo yakanaka. Nekuti shoma shoma yeHEC mune aqueous mhinduro inogona kuwana zvirinani kuchengetedza mvura, kuitira kuti sisitimu inoderedza kudiwa kwemvura mukugadzirira. Pasina kuchengetwa kwemvura uye kunamatira, simende dhaka inoderedza simba rayo uye kunamatira, uye ivhu richaderedzawo plastiki pasi pekumanikidzwa kumwe.

Nzira yekushandisa yehydroxyethyl cellulose HECmu latex pendi

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 akashongedzerwa mai mvura kumirira: nzira iyi kutanga akashongedzerwa pamwe yepamusoro pendi yemvura yaamai, uye wobva wawedzera latex pendi, zvakanakira nzira iyi mukuru kuchinjika, anogona zvakananga akawedzera pendi apera zvigadzirwa, asi inofanira kuva zvakakodzera 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 mashanu kusvika makumi matatu, iyo hydroxyethyl cellulose ino hydrolyze uye inosimuka zvinooneka. Muchirimo, hunyoro hwemvura hwakanyanya kukwira kuti usashandise porridge.

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.

Cherechedzai

4.1 Pamberi uye mushure mekuwedzera hydroxyethyl cellulose, inofanira kusimudzwa nguva dzose kusvikira mhinduro yacho yakanyatsojeka uye yakajeka.

4.2. Sefa iyo hydroxyethyl cellulose musanganiswa tangi zvishoma nezvishoma. Usaiwedzere mutangi rekusanganisa muhuwandu hukuru kana zvakananga muhuwandu kana spherical hydroxyethyl cellulose.

4.3 tembiricha yemvura uye pH kukosha kwemvura zvine hukama huri pachena nekuparara kwehydroxyethyl cellulose, saka kutarisisa kwakanyanya kunofanirwa kubhadharwa kwairi.

4.4Usawedzera chimwe chinhu chakakosha kumusanganiswa usati hydroxyethyl cellulose poda yanyikwa nemvura. Kusimudza pH mushure mekunyura kunobatsira kunyungudika.

4.5 Sezvinobvira, kutanga kuwedzera kwe mildew inhibitor.

4.6 Paunenge uchishandisa high viscosity hydroxyethyl cellulose, kuwanda kwedoro raamai hakufaniri kunge kwakakwirira kudarika 2.5-3% (kuburikidza nehuremu), kana zvisina kudaro amai doro rakaoma kushanda.

Zvinhu zvinokanganisa viscosity yepende ye latex

1 Iyo yakawanda yakasara mabhubhu emhepo mupende, iyo inowedzera viscosity.

2 Huwandu hwe activator uye mvura mupendi fomula inowirirana here?

3 mukugadzirwa kwelatex, yakasara inokonzeresa oxide yehuwandu hwehuwandu.

4. Chiyero chemamwe masikirwo anokora mupendi fomula uye chiyero chepimo neHEChydroxyethyl cellulose.)

5 mukugadzira pende, kurongeka kwematanho ekuwedzera thickener kwakakodzera.

6 Nekuda kwekunyanya kuvhiringika uye kunyorova kwakanyanya panguva yekupararira.

7 Microbial erosion ye thickener.
