(1) Kutsunga kweHPMCviscosity: Chigadzirwa chakaomeswa chinogadzirirwa mumushonga wemvura ine huremu hwe2 °C, uye inoyerwa neNDJ-1 rudzi rwekutenderera viscometer;
(2) Kutaridzika kwechigadzirwa ihupfu, uye chigadzirwa chiriporipo chakaiswa "s" muzita rechiratidzo.
Nzira yekushandisa sei hydroxypropyl methylcellulose?
Inowedzerwa zvakananga panguva yekugadzirwa. Iyi nzira ndiyo yakapfava uye ipfupi inotora nguva. Matanho chaiwo ndeaya:
1. Wedzera humwe huwandu hwemvura inofashaira kune mudziyo unokurudzira une shear stress yakakura (iyo hydroxyethyl cellulose chigadzirwa chinosanganiswa 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 zvanyikwa;
4. Wedzera mvura inotonhorera yakakwana uye ramba uchikurudzira kusvikira zvigadzirwa zvose zvanyungudutswa zvachose (kujekesa kwekugadzirisa zviri pachena kuwedzera);
5. Zvadaro wobva wawedzera zvimwe zvinoshandiswa mukugadzirisa.
Gadzirai doro raamai kuti rishandiswe: Iyi nzira ndeyekugadzirira chigadzirwa mudoro raamai rine huwandu hwepamusoro, uye wozowedzera kune chigadzirwa. Zvakanakira ndezvekuti ine hukuru hwekuchinjika uye inogona kuwedzerwa zvakananga kune yakapedzwa chigadzirwa. Matanho acho akafanana ne (1-3) mune yakananga nzira yekuwedzera. Mushure mekunge chigadzirwa chacho chanyatsonyorova, rega chimire kuti kutonhora kwepanyama kunyunguduke, uye wozonyatso kurunga usati washandisa. Izvo zvinofanirwa kucherechedzwa kuti iyo antifungal agent inofanirwa kuwedzerwa kuna amai doro nekukurumidza.
Dry kusanganisa kushandiswa: Mushure mekuoma zvakakwana kusanganisa chigadzirwa chehupfu uye zvinhu zvehupfu (senge simende, gypsum poda, dongo redongo, nezvimwewo), wedzera huwandu hwakakodzera hwemvura, uye nyatsokanya uye kurunga kusvikira chigadzirwa chanyungudika zvachose.
Kuparara kwezvinhu zvinosanganiswa nemvura inotonhora: mvura inotonhora inonyungudika zvigadzirwa zvinogona kuwedzerwa zvakananga kumvura inotonhora kuti iparadzwe. Mushure mekuwedzera mvura inotonhora, chigadzirwa chichanyura nokukurumidza. Mushure mekunyorova kweimwe nguva yenguva, tanga kubvongodza kusvika yanyungudika zvachose.
Chengetedzo pakugadzirira mhinduro
(1) Zvigadzirwa zvisina kurapwa kwepamusoro (kunze kwehydroxyethyl cellulose) hazvizonyungudiswe zvakananga mumvura inotonhora;
(2) Inofanira kuiswa zvishoma nezvishoma mumudziyo wekuvhenganisa, uye usawedzera zvakananga chigadzirwa chakaumbwa muvharo mumudziyo wekusanganiswa muhuwandu hwakawanda;
(3) Iyo pH kukosha kwekushisa kwemvura nemvura ine hukama hwakakosha nekuparara kwechigadzirwa, uye kutarisisa kwakanyanya kunofanirwa kubhadharwa;
(4) Usawedzera mamwe alkaline zvinhu kune musanganiswa pamberi pechigadzirwa poda yakanyoroveswa nemvura, uye kuwedzera pH kukosha mushure mekunyorova, izvo zvichabatsira kupera;
(5) Sezvinobvira, wedzera antifungal mumiririri pachine nguva;
(6) Paunenge uchishandisa zvigadzirwa zvepamusoro-viscosity, uremu hwechinwiwa chaamai hahufanire kunge hwakakwirira kupfuura 2.5-3%, kana zvisina kudaro doro raamai rakaoma kushanda;
(7) Zvigadzirwa zvakarapwa nekukurumidza hazvifanirwe kushandiswa muchikafu kana zvigadzirwa zvemishonga.
