Maitiro ekushandisa hydroxyethyl cellulose mu latex pendi
1. Hydroxyethyl cellulose inoshandiswa kugadzira porridge: Sezvo hydroxyethyl cellulose isiri nyore kunyunguduka mune zvinonyungudutsa zvehupenyu, mamwe magadzirirwo emagetsi anogona kushandiswa kugadzira porridge.Mvura yeaizi zvakare inonyungudutsa isina kunaka, saka mvura yechando inowanzoshandiswa pamwe chete nezvinwiwa zvemuchadenga kugadzira porridge.Porridge-senge hydroxyethyl cellulose inogona kuwedzerwa zvakananga kune latex pendi.Hydroxyethyl cellulose yakanyudzwa zvizere muporridge.Kana yawedzerwa kupende, inonyunguduka nekukurumidza uye inoita seyakakora.Mushure mekuwedzera, ramba uchikurudzira kusvika iyo hydroxyethyl cellulose yakapararira uye yakanyungudika.Kazhinji, porridge inogadzirwa nekusanganisa zvikamu zvitanhatu zveorganic solvent kana ice water nechikamu chimwe chehydroxyethyl cellulose.Mushure memaminitsi anenge 5-30, iyo hydroxyethyl cellulose ichave ine hydrolyzed uye kuzvimba zviri pachena.(Yeuchidzo kuti hunyoro hwemvura yakawanda hwakanyanya muzhizha, saka haifanirwe kushandiswa kugadzira porridge.)
2. Wedzera hydroxyethyl cellulose zvakananga paunenge uchikuya pigment: Iyi nzira iri nyore uye inotora nguva pfupi.Iyo yakadzama nzira ndeyekutevera:
(1) Wedzera huwandu hwakakodzera hwemvura yakacheneswa mubhaketi hombe remusanganisi wekugera (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 zvidimbu zvose zvapararira uye zvanyorova
(4) Wedzera anti-mildew additives kugadzirisa kukosha kwePH
(5) Shingairira kusvikira yose hydroxyethyl cellulose yakanyungudutswa zvachose (viscosity yemhinduro inowedzera zvakanyanya), wobva wawedzera zvimwe zvikamu mufomu, uye geda kusvikira pende yagadzirwa.
3. Gadzirira hydroxyethyl cellulose nedoro raamai kuti ugozoshandisa gare gare: Iyi nzira ndeyekugadzirira amai doro rine uwandu hwepamusoro pekutanga, wozowedzera kupende yelatex.Kubatsira kweiyi nzira ndeyokuti inonyanya kushanduka uye inogona kuwedzerwa zvakananga kupende yakapedzwa, asi inofanira kuchengetwa zvakanaka..Matanho uye nzira dzakafanana nematanho (1) - (4) mu nzira 2, mutsauko ndewekuti hapana high-shear agitator inodiwa, uye chete mamwe agitator ane simba rakakwana kuchengetedza hydroxyethyl fiber yakapararira zvakaenzana mumushonga ndiyo Can. .Ramba uchikurudzira nguva dzose 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 iri poda yakagadziriswa, zviri nyore kuibata uye kuinyungudutsa mumvura chero bedzi zvinhu zvinotevera zvakabhadharwa.
(1) Pamberi uye mushure mekuwedzera hydroxyethyl cellulose, inofanira kusimudzwa nguva dzose kusvikira mhinduro yacho yakanyatsojeka uye yakajeka.
(2) Inofanirwa kupepetwa zvishoma nezvishoma mutangi rekusanganisa, uye usawedzera zvakananga huwandu hukuru hwehydroxyethyl cellulose yakagadzira mapundu kana mabhora mutangi rekusanganisa.
(3) Tembiricha yemvura uye pH kukosha mumvura zvine hukama hwakakosha nekuparara kwehydroxyethyl cellulose, saka kutariswa kwakanyanya kunofanirwa kubhadharwa.
(4) Usawedzera zvimwe alkaline zvinhu musanganiswa usati hydroxyethyl cellulose poda yakanyikwa nemvura.Kusimudza pH mushure mekunyorova kunobatsira kupera.
(5) Sezvinobvira, wedzera anti-fungal mumiririri kare.
(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) Nekuda kwekunyanya kubvongodza, hunyoro hunopisa panguva yekupararira.
(2) Huwandu hwemamwe masikirwo anokora mukugadzirwa kwepende uye chiyero chehuwandu kune hydroxyethyl cellulose.
(3) Kana huwandu hwesurfactant uye huwandu hwemvura inoshandiswa mufomu yependi yakakodzera.
(4) Paunenge uchigadzira latex, huwandu hweokisidhi yemukati seyasara inokonzeresa.
(5) Corrosion of thickener by microorganisms.
(6) Mukugadzira pendi, ingave nhanho yekutevedzana yekuwedzera thickener yakakodzera.
7 Kana maturu emhepo achiramba ari mupende, ndipo panobva pawedzera viscosity
