Pendi yegiredhi HEC

Giredhi rependiHEC Hydroxyethyl cellulose imhando yepolymer isinganyungudike mumvura, chena kana yero, inoyerera nyore, haina hwema uye haina kunaka, inogona kunyungudika mumvura inotonhora neinopisa, uye mwero wekunyungudika unowedzera nekupisa, kazhinji isinganyungudike muzvinhu zvakawanda zvinonyungudika. Ine kugadzikana kwakanaka kwePH uye shanduko shoma ye viscosity muhuwandu hweph2-12. HEC ine munyu wakawanda uye kugona kwe hygroscopic, uye ine simba rakasimba rekuchengetedza mvura. Mhinduro yayo yemvura ine basa repamusoro uye zvigadzirwa zve viscosity yakakwira zvine pseudoplasticity yakakwira. Inogona kugadzirwa kuita firimu rinopenya risina mvura rine simba riri pakati nepakati, risingasvibiswi nyore nemafuta, risingakanganiswe nechiedza, richine firimu rinonyungudika re HEC mumvura. Mushure mekugadzirisa pamusoro, HEC inopararira uye haisangani mumvura, asi inonyungudika zvishoma nezvishoma. PH inogona kugadziriswa kuita 8-10 uye inonyungudika nekukurumidza.

Zvivakwa zvikuru

Hydroxyethyl cellulose(HEC)Zviri pachena kuti inogona kunyungudutswa mumvura inotonhora nemvura inopisa, uye haina hunhu hwegel. Ine mhando dzakasiyana dzekuchinja, kunyunguduka uye kusimba. Ine kugadzikana kwakanaka kwekupisa (pasi pe140°C) uye haiburitse mvura kana mamiriro eacidic. Mhinduro yehydroxyethyl cellulose (HEC) inogona kugadzira firimu rinoonekera, rine zvinhu zvisiri zveionic zvisingashande nemaion uye zvine hukama hwakanaka.

Senzira yekudzivirira colloid, Paint grade HEC inogona kushandiswa pakugadzira vinyl acetate emulsion polymerization kuti ivandudze kugadzikana kwe polymerization system muhuwandu hwakakura hwePH. Mukugadzira zvigadzirwa zvakapedzwa, pigment, filler nezvimwe zvinowedzera zvakapararira zvakaenzana, zvakagadzikana uye zvinopa simba rekukora. Inogona zvakare kushandiswa pa styrene, acrylic, acrylic uye mamwe ma suspended polymers se dispersants, inoshandiswa mu latex pendi inogona kuvandudza zvakanyanya kukora, kuvandudza mashandiro e leveling.

Nzira yekushandisa hydroxyethyl cellulose HEC mumvura inoyererapendi

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

(1) Wedzera mvura yakachena yakakodzera muVAT yechinhu chinochera zvakanyanya (kazhinji, ethylene glycol, chinhu chinonyorovesa uye chinhu chinoita firimu zvinowedzerwa panguva ino)

(2) Tanga kukurunga nekumhanya kwakaderera wobva wawedzera zvishoma nezvishoma hydroxyethyl cellulose

(3) Ramba uchikurunga kusvika zvidimbu zvese zvanyorova

(4) wedzera mushonga unodzivirira mildew, PH regulator, nezvimwewo

(5) Kurunga kusvika hydroxyethyl cellulose yese yanyungudika zvachose (kunaka kwemushonga kwawedzera zvakanyanya) usati wawedzera zvimwe zvikamu mufomura, wobva wakuya kusvika yava pendi.

2. yakashongedzwa nemvura inomirira amai: nzira iyi inotanga yakashongedzwa nemvura inoyerera yakawanda, wobva waisa pendi yelatex, mukana weiyi nzira ndeyekuchinjika kukuru, inogona kuwedzerwa zvakananga kuzvigadzirwa zvependi zvakapedzwa, asi inofanira kunge yakachengetwa zvakakodzera. Matanho nenzira dzakafanana nematanho (1) - (4) muNzira 1, kunze kwekuti agitator inocheka zvakanyanya haidiwi uye imwe agitator ine simba rakakwana rekuchengetedza hydroxyethyl fibers yakapararira zvakaenzana mumushonga yakakwana. Ramba uchikurunga kusvika yanyungudika zvachose kuita mhinduro gobvu. Cherechedza kuti mushonga unodzivirira mildew unofanirwa kuwedzerwa kune doro rinoyerera amai nekukurumidza sezvinobvira.

3. Phenology yakaita sePorridge: Sezvo organic solvents isiri organic solvents yakaipa ye hydroxyethyl cellulose, organic solvents idzi dzinogona kugadzirirwa porridge. organic solvents dzinonyanya kushandiswa dzakadai se ethylene glycol, propylene glycol, uye firimu forming agents (senge hexadecanol kana diethylene glycol butyl acetate), mvura yechando hainawo solvent yakanaka, saka mvura yechando inowanzo shandiswa neorganic liquids muporridge. Gruel - yakafanana ne hydroxyethyl cellulose inogona kuwedzerwa zvakananga mupendi. Hydroxyethyl cellulose yazara muchimiro cheporridge. Mushure mekuwedzera lacquer, nyungudutsa pakarepo uye iite thickening effect. Mushure mekuwedzera, ramba uchikurunga kusvika hydroxyethyl cellulose yanyungudika zvachose uye yakaenzana. Porridge yakajairika inogadzirwa nekusanganisa zvikamu zvitanhatu zveorganic solvent kana ice water nechikamu chimwe che hydroxyethyl cellulose. Mushure memaminitsi angangoita 5-30, Paint gradeHECInonyungudutsa mvura uye inokwira zvinooneka. Muzhizha, hunyoro hwemvura hwakanyanya kukwira zvekuti hahushandiswi seporiji.

4. Zvinhu zvinoda kutariswa pakushandisa hydroxyethyl cellulose mother liquor:

Pchenjedzo

1 Usati waisa giredhi rependi uye mushure mekuwedzeraHEC, inofanira kuzungunuswa nguva dzose kusvika mhinduro yacho yanyatsojeka uye yakajeka.

2. Sefa hydroxyethyl cellulose mutangi rekusanganisa zvishoma nezvishoma. Usaiise mutangi rekusanganisa yakawanda kana zvakananga mumhando yependi yakawanda kana kuti yakatenderera.HEC.

3 tembiricha yemvura uye pH kukosha kwemvura zvine hukama hwakajeka nekunyungudika kwegiredhi rependiHEChydroxyethyl cellulose, saka kutarisisa kwakakosha kunofanira kupihwa kwairi.

Usawedzera zvimwe zvinhu zvinokosha mumusanganiswa usati waisa pendi muchikamu chependi.HECUpfu hwehydroxyethyl cellulose hunonyikwa nemvura. Kuwedzera pH mushure mekunyikwa kunobatsira kunyungudika.

5. Nepose pazvinogoneka, kuwedzera mushonga unodzivirira mildew nekukurumidza.

6 Kana uchishandisa pendi ine viscosity yakakuraHEC, huwandu hwedoro raamai harifanirwe kupfuura 2.5-3% (nehuremu), zvikasadaro doro raamai rinonetsa kushandisa.

Zvinhu zvinokanganisa viscosity yependi yelatex

1. Mafuro emhepo akawanda akasara mupendi, ndiko kuwedzera kwe viscosity.

2. Huwandu hwe activator nemvura mufomura yependi zvinoenderana here?

3 mukugadzirwa kwelatex, huwandu hwe catalyst oxide hwasara.

4. Chiyero chezvimwe zvinhu zvinosimbisa ganda zvechisikigo mufomura yependi uye chiyero cheyero yeyero negiredhi rependiHEC.)

5. Pakugadzira pendi, kurongeka kwematanho ekuwedzera chinhu chinogozha kwakakodzera.

6.Nekuda kwekuvhunduka kwakanyanya uye hunyoro hwakawanda panguva yekupararira.

7. Kukukurwa kwechinhu chinogocha ganda nehutachiona.
