(1) Kutsunga kweviscosity: Chigadzirwa chakaomeswa chinogadzirirwa mumushonga wemvura ine uremu hwe2 ° C, uye inoyerwa neNDJ-1 rotational viscometer;
(2) Kuonekwa kwechigadzirwa kune upfu, uye chigadzirwa chekare chinosungirirwa ne "s".
Maitiro ekushandisa hydroxypropyl methylcellulose
Wedzera zvakananga panguva yekugadzira, nzira iyi ndiyo yakapusa uye ipfupi-inopedza nguva nzira, iwo matanho chaiwo ndeaya:
1. Wedzera humwe huwandu hwemvura inopisa mumudziyo wakavhenganiswa neshear stress yakakura (hydroxyethyl cellulose zvigadzirwa zvinonyunguduka mumvura inotonhora, saka wedzera mvura inotonhora);
2. Vhura iyo inofambisa pamhepo yakaderera, uye zvishoma nezvishoma sieve chigadzirwa mumudziyo unofambisa;
3. Ramba uchikurunga kusvika zvidimbu zvese zvatota;
4. Wedzera huwandu hwakakwana hwemvura inotonhora uye ramba uchikurudzira kusvikira zvigadzirwa zvose zvanyungudutswa zvachose (kujekesa kwemhinduro kunowedzera zvakanyanya);
5. Zvadaro wobva wawedzera zvimwe zvigadzirwa mufomu.
Gadzirira doro raamai kuti rishandiswe: Nzira iyi ndeyekuita kuti chigadzirwa chive doro raamai rine huwandu hwepamusoro pekutanga, uye wozowedzera kuchigadzirwa. Zvakanakira ndezvekuti ine hukuru hwekuchinjika uye inogona kuwedzerwa zvakananga kune yakapedzwa chigadzirwa. Matanho acho akafanana nematanho (1-3) mune yakananga nzira yekuwedzera. Mushure mekunge chigadzirwa chacho chanyatsonyoroveswa, rega chimire kuti kutonhora kwepanyama kunyunguduke, uye wobva wawedzera zvakakwana usati washandisa. Izvo zvinofanirwa kucherechedzwa kuti iyo antifungal agent inofanirwa kuwedzerwa kuna amai doro nekukurumidza.
Dry mixing: Mushure mekuoma zvakakwana kusanganisa chigadzirwa cheupfu uye zvinhu zvehupfu (zvakadai semende, gypsum powder, dongo redongo, nezvimwewo), wedzera huwandu hwakakodzera hwemvura, kanya uye kurunga kusvikira chigadzirwa chanyungudika zvachose.
Kunyungudika kwezvinhu zvinonyunguduka zvemvura inotonhora: mvura inotonhorera inonyungudika zvigadzirwa zvinogona kuwedzerwa zvakananga kumvura inotonhora yekuparara. Mushure mekuwedzera mvura inotonhora, chigadzirwa chichanyura nokukurumidza. Mushure mekunyorova kweimwe nguva yenguva, tanga kubvongodza kusvika yapera zvachose.
Chengetedzo pakugadzirira mhinduro
(1) Zvigadzirwa zvisina kurapwa kwepamusoro (kunze kwehydroxyethyl cellulose) hazvizonyungudiswe zvakananga mumvura inotonhora;
(2) Inofanirwa kupepetwa zvishoma nezvishoma mumudziyo wekusanganisa, usawedzera zvakananga huwandu hukuru kana chigadzirwa chakaumbwa mubhokisi mumudziyo wekusanganisa;
(3) Kupisa kwemvura uye ph kukosha kwemvura kune hukama huri pachena nekuparara kwechigadzirwa, saka kunyanya kukoshesa kunofanira kubhadharwa;
(4) Usawedzera mamwe alkaline zvinhu kune musanganiswa pamberi pechigadzirwa poda yakanyoroveswa nemvura, uye wedzera ph kukosha mushure mekunyorova, izvo zvichabatsira kunyungudika;
(5) Sezvinobvira, wedzera antifungal mumiririri pachine nguva;
(6) Paunenge uchishandisa zvigadzirwa zvepamusoro-viscosity, uremu hwehuremu hwedoro raamai haufanire kunge hwakakwira kupfuura 2.5-3%, zvikasadaro doro raamai richava rakaoma kushanda;
(7) Zvigadzirwa zvakanyungudika pakarepo hazvifanirwe kushandiswa muchikafu kana zvigadzirwa zvemishonga.
