Maitiro ekushandisa hydroxyethyl cellulose mu latex pendi
1. Hydroxyethyl cellulose inoshandiswa kugadzirira porridge: Sezvo hydroxyethyl cellulose isiri nyore kunyunguduka mumagetsi emagetsi, mamwe magadzirirwo emagetsi anogona kushandiswa kugadzira porridge.Mvura yeaizi zvakare haina kunyungudika, saka mvura yechando inowanzoshandiswa neorganic liquid kugadzira porridge.Iyo porridge-senge hydroxyethyl cellulose inogona kuwedzerwa zvakananga kune latex pendi.Iyo hydroxyethyl cellulose yakazvimba zvizere muporridge.Kana yawedzerwa kupende, inonyungudika nekukurumidza uye inoita basa rekukora.Mushure mekuwedzera, zvichiri kudikanwa kuti urambe uchikurudzira kusvikira iyo hydroxyethyl cellulose yakapararira zvachose uye yakanyungudika.Kazhinji, porridge inosanganiswa nezvikamu zvitanhatu zveorganic solvent kana ice water uye chikamu chimwe chehydroxyethyl cellulose.Mushure memaminitsi angangoita 5-30, iyo hydroxyethyl cellulose ichave hydrolyzed uye kuzvimba zviri pachena.(Zvinokurudzirwa kuti hunyoro hwemvura yakawanda hwakanyanya muzhizha, saka hazvina kukodzera kushandiswa porridge.)
2. Wedzera hydroxyethyl cellulose zvakananga paunenge uchikuya pigment: Iyi nzira iri nyore uye inotora nguva shoma.Iyo yakadzama nzira ndeyekutevera:
(1) Wedzera yakakodzera mvura yakachena kune vheti ye-high-cut agitator (kazhinji, zvigadzirwa zvekugadzira firimu uye zvinonyorovesa zvinowedzerwa panguva ino)
(2) Tanga kubvongodza uchienderera mberi nekumhanya kwakaderera uye zvishoma nezvishoma uye zvakaenzana wedzera hydroxyethyl cellulose
(3) Ramba uchikurunga kusvikira zvimedu zvose zvaparadzirwa zvakafanana uye zvanyorova
(4) Wedzera antifungal additives kugadzirisa PH kukosha
(5) Shingairira kusvikira yose hydroxyethyl cellulose yakanyungudutswa zvachose (iyo viscosity yemhinduro inowedzera zvakanyanya), wobva wawedzera zvimwe zvikamu mufomu, uye kugaya kusvikira yava pende.
3. Gadzirira hydroxyethyl cellulose nedoro raamai kuti ushandise: Nzira iyi ndeyekugadzira doro raamai nepamusoro pekutanga, uye wobva wawedzera kupende yelatex.Kubatsira kweiyi nzira ndeyokuti inonyanya kushanduka uye inogona kuwedzerwa zvakananga kupende yakapedzwa, asi inoda kuchengetwa zvakanaka..Matanho uye nzira dzakafanana nematanho (1) - (4) mu nzira 2, mutsauko ndewekuti hapana chikonzero chepamusoro-shear agitator, uye mamwe maagitator ane simba rakakwana kuchengetedza hydroxyethyl fibers yakapararira mu mhinduro inoshandiswa.Inogona.Ramba uchikurudzira kusvikira yanyungudika zvachose muine viscous solution.Izvo zvinofanirwa kucherechedzwa kuti iyo antifungal agent inofanirwa kuwedzerwa kune pendi mai doro nekukurumidza sezvinobvira.
4 Nyaya dzinoda kutariswa pakugadzirira hydroxyethyl cellulose doro raamai
Sezvo hydroxyethyl cellulose ipfu yakagadziriswa, zviri nyore kubata uye kunyunguduka mumvura chero bedzi zvinhu zvinotevera zvichionekwa.
(1) Pamberi uye mushure mekuwedzera hydroxyethyl cellulose, inofanira kuchengetwa ichikurudzira kusvikira mhinduro yacho yakanyatsojeka uye yakajeka.
(2) Inofanira kusefa mudhiri rekuvhenganisa zvishoma nezvishoma.Usawedzera zvakananga iyo hydroxyethyl cellulose yakaumbwa kuita mapundu nemabhora mugomba rekusanganisa muhuwandu hukuru kana zvakananga.
(3) Tembiricha yemvura uye pH kukosha mumvura zvine hukama hwakakosha pakuparara kwehydroxyethyl cellulose, saka kutarisisa kunofanirwa kubhadharwa.
(4) Usawedzera mamwe alkaline zvinhu musanganiswa usati hydroxyethyl cellulose poda yakanyoroveswa nemvura.Kusimudza pH chete mushure mekunyorova kunobatsira mukuparara.
(5) Sezvinobvira, wedzera antifungal mumiririri nekukurumidza sezvinobvira.
(6) Paunenge uchishandisa high-viscosity hydroxyethyl cellulose, kusanganiswa kwedoro raamai hakufaniri kunge kwakakwirira kudarika 2.5-3% (kuburikidza nehuremu), kana zvisina kudaro doro raamai richava rakaoma kubata.
Zvinhu zvinokanganisa viscosity yepende ye latex:
(1) Humidity yakanyanyisa panguva yekupararira nekuda kwekunyanya kubvongodza.
(2) Muyero wemamwe masikirwo akakora uye chiyero cheyero yehydroxyethyl cellulose mune pendi fomula.)
(3) Kana huwandu hwesurfactant uye huwandu hwemvura mufomula yepende yakakodzera.
(4 Paunenge uchigadzira latex, huwandu hwezvasara zvinokonzeresa uye mamwe maokisi.
5 Kukukurwa kwehutachiona hwemakobvu.
6 Panguva yekugadzira pendi, kutevedzana kwematanho ekuwedzera makobvu kwakakodzera here?
7 Kukwira kuri kuita mabubbles emhepo akasara mupende, ndiko kuwedzera kwe viscosity
