(1) Kutsunga kweviscosity: chigadzirwa chakaomeswa chinogadzirirwa mumushonga wemvura ine uremu hwe2 ° C, uye inoyerwa ne ndj-1 rotational viscometer;
(2) Kuonekwa kwechigadzirwa kune upfu. Chigadzirwa chiriporipocho chinoiswa "s" uye chigadzirwa chegiredhi chemishonga chinoiswa "y". Semuenzaniso, me-4000s ndicho chigadzirwa chekare che me-4000.
01. Mashandisiro e hydroxypropyl methylcellulose
Wedzera zvakananga panguva yekugadzira, nzira iyi ndiyo yakapusa uye ipfupi-inopedza nguva nzira, iwo matanho chaiwo ndeaya:
1. Wedzera imwe mvura inofashaira mumudziyo unobvongodza ine shear stress yakanyanya (hydroxyethyl cellulose zvigadzirwa zvinonyungudika mumvura inotonhora, saka ingowedzera 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 rizoshandiswa: Iyi nzira 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 chanyatsonyorova, rega chimire kuti kutonhora kwepanyama kunyunguduke, uye wobva wanyatso kurunga usati washandisa. Izvo zvinofanirwa kucherechedzwa kuti iyo antifungal agent inofanirwa kuwedzerwa kuna amai doro nekukurumidza.
Dry mixing: mushure mekuoma kwakazara kusanganisa chigadzirwa cheupfu uye zvinhu zvehupfu (zvakadai semende, gypsum powder, dongo redongo, nezvimwewo), wedzera huwandu hwakakodzera hwemvura, kanya uye fambisa kusvikira chigadzirwa chacho chanyunguduka zvachose.
Kuparara kwezvinhu zvinosanganiswa nemvura inotonhora: mvura inotonhora inonyungudika zvigadzirwa zvinogona kuwedzerwa zvakananga kumvura inotonhora kuti iparadzwe. Mushure mekuwedzera kumvura inotonhora, chigadzirwa chichanyura nokukurumidza. Mushure mekunyorova kweimwe nguva yenguva, tanga kubvongodza kusvika yapera zvachose.
02. 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 kuita bhuroka mumudziyo wekusanganisa.
(3) Tembiricha yemvura uye ph kukosha kwemvura zvine hukama huri pachena nekuparara kwechigadzirwa, saka kutarisisa kwakanyanya kunofanirwa kubhadharwa.
(4) Usawedzera mamwe alkaline zvinhu musanganiswa usati chigadzirwa poda yanyikwa nemvura. Kusimudza pH mushure mekunyura kunobatsira kunyungudika.
(5) Sezvingabvira, wedzera antifungal mumiriri pamberi.
(6) Paunenge uchishandisa zvigadzirwa zvepamusoro-viscosity, uremu hwechinwiwa chaamai hahufanire kunge hwakakwirira kupfuura 2.5-3%, kana zvisina kudaro doro raamai richava rakaoma kubata.
(7) Zvigadzirwa zvakanyungudika pakarepo hazvifanirwe kushandiswa muchikafu kana zvigadzirwa zvemishonga.
