1. Wedzera zvakananga paunenge uchikuya pigment: Iyi nzira ndiyo iri nyore uye inotora nguva shoma.Matanho akadzama ndeaya:
(1) Wedzera mvura yakacheneswa yakakodzera kune vat ye-high-cut agitator (kazhinji, ethylene glycol, wetting agent uye film-forming agent zvose zvinowedzerwa panguva ino)
(2) Tanga kubvongodza uchienderera nekumhanya kwakaderera uye zvishoma nezvishoma wowedzera hydroxyethyl cellulose
(3) Ramba uchikurunga kusvikira zvimedu zvese zvanyikwa
(4) Wedzera antifungal mumiriri, PH inogadzirisa, nezvimwe.
(5) Kurudzira kusvikira yese hydroxyethyl cellulose yanyungudika zvachose (iyo viscosity yemushonga inowedzera zvakanyanya) usati wawedzera zvimwe zvikamu mufomu, uye kugaya kusvika yava pendi.
2. Gadzirirai doro raamai kuti rizoshandiswa: Nzira iyi kugadzirira amai doro zvine mwero wakanyanya kutanga, wozoisa papende yelatex.Kubatsira kweiyi nzira ndeyokuti ine hukuru hukuru uye inogona kuwedzerwa zvakananga kupende yakapedzwa, asi inofanira kuchengetwa zvakanaka.Matanho uye nzira dzakafanana nematanho (1) - (4) muMethod 1, mutsauko ndewekuti hapana chikonzero che-high-shear agitator, uye chete mamwe agitator ane simba rakakwana kuchengetedza hydroxyethyl fibers yakapararira mukati. mhinduro inoshandiswa.Inogona.Ramba uchikurudzira kusvikira yanyungudika zvachose muine viscous solution.Izvo zvinofanirwa kucherechedzwa kuti iyo antifungal agent inofanirwa kuwedzerwa kuna amai doro nekukurumidza.
3. For porridge phenology: Sezvo organic solvents ari urombo solvents for hydroxyethyl cellulose, izvi organic solvents anogona kushandiswa kugadzira porridge.Iyo inonyanya kushandiswa organic solvents senge ethylene glycol, propylene glycol, uye mafirimu-forming agents (akadai sehexylene glycol kana diethylene glycol butyl acetate), mvura yechando zvakare inonyungudutsa isina kunaka, saka mvura yechando inowanzoshandiswa pamwe chete neorganic liquids.Kugadzirira porridge.
Iyo porridge-senge hydroxyethyl cellulose inogona kuwedzerwa zvakananga kupende.Iyo hydroxyethyl cellulose yakazvimba zvizere muporridge.Kana yakawedzerwa kupende, pakarepo inonyunguduka uye inowedzera.Mushure mekuwedzera, inofanira kusimudzwa nguva dzose kusvikira hydroxyethyl cellulose yanyungudutswa zvachose uye yakafanana.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.Muzhizha, hunyoro hwemvura yakawanda yakanyanya, uye haina kukodzera kushandiswa porridge.
4. Nyaya dzinoda kutariswa pakugadzira doro raamai rehydroxyethyl cellulose
Sezvo hydroxyethyl cellulose ipfu yakagadziriswa, zviri nyore kubata uye kunyunguduka mumvura chero bedzi zvinhu zvinotevera zvichionekwa.
1) Pamberi uye mushure mekuwedzera hydroxyethyl cellulose, zvakakosha kuti urambe uchikurudzira kusvikira mhinduro yacho yakanyatsojeka uye yakajeka.
2) Inofanirwa kupepetwa mubhodhoro rinosanganiswa zvishoma nezvishoma, uye usawedzera hydroxyethyl cellulose iyo yakaumbwa kuva mapundu kana mabhora zvakananga mumusanganiswa wekusanganiswa.
3) Tembiricha yemvura uye pH kukosha mumvura zvine hukama hwakakosha nekuparara kwehydroxyethyl cellulose, saka kutarisisa kwakanyanya kunofanirwa kubhadharwa kwairi.
4) Usawedzera mamwe alkaline zvinhu kune musanganiswa musati 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 nekurema), kana zvisina kudaro amai doro richava rakaoma kubata.
