Nzira yekushandisa hydroxyethyl cellulose mu latex pendi
1. Hydroxyethyl celluloseneporiji senge phenology: nekuti hydroxyethyl cellulose hainyunguduke nyore mu organic solvents, mamwe organic solvents anogona kushandiswa kugadzirira poriji. Mvura yechando i solvent yakaipawo, saka inowanzoshandiswa muporiji ine organic liquids. Hydroxyethyl cellulose yemhando ye congee inogona kuwedzerwa zvakananga mu emulsii pendi. Hydroxyethyl cellulose yakazadzwa muchimiro cheporiji. Kana yawedzerwa papendi, inokurumidza kunyunguduka uye kukora. Ramba uchikurunga kusvika hydroxyethyl cellulose yapararira zvachose uye yanyunguduka. Poriji yakajairika inogadzirwa nekusanganisa zvikamu zvitanhatu zve organic solvent kana mvura yechando nechikamu chimwe che hydroxyethyl cellulose. Mushure memaminitsi angangoita 5-30, hydroxyethyl cellulose inonyunguduka uye inoonekwa ichikwira. (Zvinokurudzirwa kuti hunyoro hwemvura muzhizha hwakanyanya kukwira kuti husashandiswe seporiji.)
2. Wedzera hydroxyethyl cellulose zvakananga mu pigment yekukuya: nzira iyi iri nyore uye nguva ipfupi. Nzira dzakadzama ndeidzi dzinotevera:
(1) Wedzera mvura yakachena yakakodzera muVAT yakakwira inofanira kudimbura agitator (kazhinji, zvinowedzera kugadzira firimu uye zvinonyorovesa zvinowedzerwa panguva ino)
(2) Tanga kusanganisa nekumhanya kwakaderera usingamire wobva wawedzera zvishoma nezvishoma hydroxyethyl cellulose zvakaenzana
(3) Ramba uchikurunga kusvika zvidimbu zvese zvapararira zvakaenzana uye zvanyorova
(4) Wedzera mushonga unodzivirira mildew uye gadzirisa kukosha kwePH
(5) Kurunga kusvika hydroxyethyl cellulose yese yanyungudika zvachose (kusimba kwemushonga kunowedzera zvakanyanya), wobva wawedzera zvimwe zvinhu mufomura, wobva wakuya kusvika yava pendi.
3 hydroxyethyl cellulose ine mvura yaamai yakamirira: nzira iyi inotanga yakashongedzwa nehuwandu hwakawanda hwemvura yaamai, wobva wawedzera pendi yelatex, mukana weiyi nzira unochinjika, unogona kuwedzera zvakananga zvigadzirwa zvependi zvakapedzwa, asi pakuchengetwa kwakakodzera. Matanho nenzira dzakafanana nematanho (1) - (4) muNzira 2, kunze kwekuti agitator yekucheka zvakanyanya haidiwi uye mamwe ma agger ane simba rakakwana rekuchengetedza tambo dzehydroxyethyl dzakapararira zvakaenzana mumushonga ndiwo anoshandiswa. Ramba uchikurunga kusvika yanyungudika zvachose kuita mhinduro gobvu. Cherechedza kuti: mushonga wekudzivirira ganda unofanira kuwedzerwa nekukurumidza sezvinobvira mupendi yaamai doro.
Zvinhu zvina zvinoda kutariswa pakushandisa hydroxyethyl cellulose mother liquor
Sezvo hydroxyethyl cellulose iri upfu hwakagadziriswa, zviri nyore kubata nekunyungudutsa mumvura nekutevera matanho ekudzivirira.
(1) Usati wawedzera hydroxyethyl cellulose uye mushure mekuwedzera, unofanira kuramba uchikurunga, kusvika mhinduro yacho yanyatsojeka uye yakajeka.
(2) Zvinodiwa kusveta hydroxyethyl cellulose mutangi rekusveta zvishoma nezvishoma. Usaiise yakawanda kana kuti zvakananga mutangi rekusveta.
(3) Kunyungudika kwehydroxyethyl cellulose zviri pachena kuti kune chekuita nekupisa kwemvura uye pH yemvura, saka kutarisisa kwakakosha kunofanira kupihwa pairi.
(4) Usawedzera zvimwe zvinhu zvinokosha mumusanganiswa usati wanyikwa upfu hwehydroxyethyl cellulose nemvura. Kuwedzera pH mushure mekunyikwa kunobatsira kunyungudika.
(5) Nepose pazvinogoneka, kuwedzera mushonga unodzivirira mildew nekukurumidza.
(6) Pakushandisa hydroxyethyl cellulose ine viscosity yakakura, huwandu hwedoro raamai harifanirwe kupfuura 2.5-3% (nehuremu), zvikasadaro doro raamai rinonetsa kushandisa.
Zvinhu zvinokanganisa viscosity yependi yelatex:
(1) Nekuda kwekukurunga zvakanyanya uye hunyoro hwakawanda pakupararira.
(2) huwandu hwezvimwe zvinhu zvekunakisa zvechisikigo mufomura yependi uye huwandu hwehuwandu hwayohydroxyethyl cellulose.)
(3) huwandu hwechinhu chinobatsira pamusoro pemvura uye mvura mufomura yependi zvinoenderana.
(4 mukugadzirwa kwelatex, huwandu hwe catalyst oxide inosara muhuwandu.
Kuparadzwa kwechinhu chinogokora che microbial.
6 mukugadzira pendi, kurongeka kwematanho ekuwedzera chikobvu kwakakodzera.
Kana mabhurumu emhepo akasara mupendi, viscosity inowedzera.
