Kushandiswa kwehydroxyethyl cellulose mupende ye latex ndeyotevera: 1. Wedzera zvakananga paunenge uchikuya pigment: iyi nzira iri nyore, uye nguva inoshandiswa ipfupi.Matanho akadzama ndeaya anotevera: (1) wedzera mvura yakachena yakacheneswa (kazhinji, ethylene glycol, wetting agent uye film-forming agent inowedzerwa panguva ino) (2) tanga kubvongodza nekumhanya kwakaderera uchienderera uye zvishoma nezvishoma kuwedzera hydroxyethyl cellulose (3) ramba uchikurunga kusvika zvimedu zvese zvatota (4) wedzera mildew inhibitor;PH regulator, etc. (5) fambisa kusvikira yose hydroxyethyl cellulose yakanyungudutswa zvachose (solution viscosity kuwedzera) isati yawedzera zvimwe zvikamu zvechimiro, ichikuya kusvikira pende.
2.Kushongedzerwa nedoro raamai rinomirira kushandiswa: nzira iyi inotanga yakashongedzerwa nehuwandu hwepamusoro hwedoro raamai, uyezve yakawedzerwa kune latex pendi, nzira iyi ine mukana wekuwedzera kushanduka, inogona kuwedzerwa zvakananga kune zvigadzirwa zvependi, asi inofanira kuva. yakachengetedzwa zvakanaka.Matanho uye nzira dzakafanana nematanho (1) - (4) mune nzira 1, kunze kwekuti shear agitator yakakwirira haidiwi, uye chete agitator ane simba rakakwana kuchengetedza hydroxyethyl fibers zvakafanana akaparadzirwa mumhinduro inodiwa.Ramba uchikurudzira kusvikira yanyungudika zvachose muine viscous solution.Chenjerera kuti: mildew inhibitor inofanira kuwedzerwa kudoro raamai nekukasira.3. Congee ne phenology: se organic solvents ye hydroxyethyl cellulose inonyangadza yakaipa, saka izvi zvinokonzerwa nemagetsi zvinogona kushandiswa kugadzirira congee.Inowanzo shandiswa organic solvents yakadai se ethylene glycol, propylene glycol, uye firimu-forming agents (sehexanediol kana diethylene glycol butyl acetate) , mvura yechando ihwowo husina kunaka hunonyunguduka, saka inowanzoshandiswa nemafuta emvura kugadzira porridge.Porridge-senge hydroxyethyl cellulose inogona kuwedzerwa zvakananga kupende.Hydroxyethyl cellulose yakazadzwa zvizere muporridge.Kana lacquer yawedzerwa, inonyungudika pakarepo uye inowedzera.Mushure mekuwedzera, inofanira kusimudzwa nguva dzose kusvikira hydroxyethyl cellulose yanyungudutswa zvachose uye yakafanana.Kazhinji porridge ine zvikamu zvitanhatu zveorganic solvent kana ice water uye chikamu chehydroxyethyl cellulose musanganiswa, anenge 5-30 maminetsi gare gare, hydroxyethyl cellulose ichave hydrolyzed uye kuzvimba.Zhizha apo hunyoro hwemvura huzhinji hwakanyanya, hahuna kukodzera kugadzirirwa porridge.
3.Four.Ziva paunenge uchigadzira doro raamai rehydroxyethyl cellulose sezvo hydroxyethyl cellulose iri chidimbu chehupfu, chiri nyore kushanda nekunyungudika mumvura nekuteerera kune zvinotevera.1 isati yasvika uye mushure mekuwedzera hydroxyethyl cellulose, musanganiswa unofanirwa kukurudzirwa nguva dzose kusvikira mhinduro yacho yakanyatsojeka uye yakajeka.2 inofanira kusefa mudhiramu rekusanganisa, usave nenhamba huru yemapundu kana mabhora ehydroxyethyl cellulose akawedzerwa zvakananga mudhiramu rekusanganisa.3 iyo solubility yehydroxyethyl cellulose inoenderana nekupisa kwemvura uye pH kukosha mumvura, iyo inofanirwa kutariswa zvakanyanya.4 usawedzera zvimwe zvinhu zvakakosha kumusanganiswa usati hydroxyethyl cellulose poda yazara nemvura.Kuwedzera pH mushure mekunyura kunobatsira kunyungudika.5 sezvinobvira, kutanga kuwedzera anti-mildew agent.6 paunoshandisa high viscosity hydroxyethyl cellulose, amai doro rekugadzirisa hazvigoni kuva rakakwirira kudarika 2.5-3% (gravimeter) , kana zvisina kudaro amai doro rakaoma kushanda.Zvinhu zvinokanganisa viscosity yepende ye latex:
1 Iyo yakawanda zviri mukati memhepo inoputika mupende, iyo inowedzera viscosity.2 huwandu hwepamusoro activator uye mvura inoshandiswa mupendi formula yakakodzera.3 mukugadzirwa kwe latex, huwandu hwezvakasara zvinokonzeresa uye mamwe maokisi.4 huwandu hwemamwe masikirwo akakora mufomula yepende uye chikamu nehydroxyethyl cellulose.5 mukuita pendi, kuwedzera thickener nhanho kutevedzana kwakakodzera.6 nekuda kwekunyanya kubvongodza zvekuti kana waparadzirwa mwando unopisa.7 microbial corrosion yeThickener.
