(1) Kuongororwa kwekusviba: Chigadzirwa chakaomeswa chinogadzirwa mumvura ine huremu hwe2°C, uye chinoyerwa neNDJ-1 rotational viscometer;
(2) Chitarisiko chechigadzirwa chacho chakaita seupfu, uye chigadzirwa chacho chinobva changoiswa "s".
Maitiro ekushandisa hydroxypropyl methylcellulose
Wedzera zvakananga panguva yekugadzira, nzira iyi ndiyo nzira iri nyore uye ipfupi inotora nguva, matanho chaiwo ndeaya:
1. Wedzera huwandu hwakati hwemvura inofashaira mumudziyo wakasanganiswa une stress yakanyanya (zvigadzirwa zvehydroxyethyl cellulose zvinonyungudika mumvura inotonhora, saka wedzera mvura inotonhora);
2. Batidza kusanganisa nekumhanya kwakaderera, wobva wasefa zvishoma nezvishoma chigadzirwa chacho mumudziyo wekusanganisa;
3. Ramba uchikurunga kusvika zvidimbu zvese zvanyorova;
4. Wedzera mvura inotonhora yakakwana uye ramba uchikurunga kusvika zvigadzirwa zvese zvanyungudika zvachose (kujeka kwemushonga kunowedzera zvakanyanya);
5. Wobva wawedzera zvimwe zvinoshandiswa mufomura.
Gadzirira doro remumai kuti rishandiswe: Nzira iyi ndeyekugadzira mushonga uyu kuita doro remumai rine huwandu hwakanyanya kutanga, wozowedzera kune chigadzirwa. Zvakanakira ndezvekuti une hunyanzvi hwakakura uye unogona kuwedzerwa zvakananga kune chigadzirwa chapera. Matanho acho akafanana nematanho (1-3) munzira yekuwedzera zvakananga. Mushure mekunge chigadzirwa chanyoroveswa zvizere, rega chimire kuti kutonhora kwechisikigo kunyungudike, wobva wasanganisa zvizere usati washandisa. Zvinofanira kucherechedzwa kuti mushonga wekuuraya fungus unofanirwa kuwedzerwa kune doro remumai nekukurumidza sezvinobvira.
Kusanganisa zvisina kuoma: Mushure mekusanganisa zvese zvaoma, upfu nezvinhu zveupfu (senge simende, upfu hwegypsum, ivhu receramic, nezvimwewo), wedzera mvura yakakodzera, kanda wobva wakurunga kusvika zvanyungudika zvachose.
Kunyungudika kwezvinhu zvinonyungudika mumvura inotonhora: zvinhu zvinonyungudika mumvura inotonhora zvinogona kuwedzerwa zvakananga mumvura inotonhora kuti zvinyungudike. Mushure mekuwedzera mvura inotonhora, chigadzirwa chinonyura nekukurumidza. Mushure mekunyorova kwenguva yakati, tangai kukurunga kusvika zvanyungudika zvachose.
Kungwarira pakugadzirira mhinduro
(1) Zvigadzirwa zvisina kugadziriswa pamusoro (kunze kwehydroxyethyl cellulose) hazvifanirwe kunyungudutswa zvakananga mumvura inotonhora;
(2) Inofanira kuseferwa zvishoma nezvishoma mumudziyo wekusanganisa, usawedzera zvakananga huwandu hwakawanda kana chigadzirwa chakaita bhuroko mumudziyo wekusanganisa;
(3) Tembiricha yemvura uye ph yemvura zvine hukama hwakajeka nekunyungudika kwechigadzirwa, saka kutarisisa kwakakosha kunofanira kupihwa;
(4) Usawedzera zvimwe zvinhu zvine alkaline mumusanganiswa usati wanyikwa upfu hwechigadzirwa nemvura, uye wedzera ph kana wanyikwa, izvo zvichabatsira kunyungudika;
(5) Nepose pazvinogoneka, wedzera mushonga wekuuraya fungus pachine nguva;
(6) Pakushandisa zvigadzirwa zvine viscosity yakakwira, huwandu hwehuremu hwedoro remuzvarirwo harifanirwe kupfuura 2.5-3%, zvikasadaro doro remuzvarirwo richave rakaoma kushandisa;
(7) Zvinhu zvakanyungudutswa ipapo ipapo hazvifanirwe kushandiswa muzvigadzirwa zvekudya kana zvemishonga.
