Hydroxyethyl Cellulose (HEC) isiri-ionic mvura-inonyungudika polima inoshandiswa zvakanyanya mukukoira, zvizorwa, zvekugezesa uye zvekuvakisa. Nekuda kwekukora kwayo kwakanaka, kudzikamisa uye kugadzira firimu, inoda kunyungudika mumvura kuti iite yunifomu mhinduro kana ichishandiswa.
1. Kuparara kwekugadzirira
Zvishandiso zvinodiwa uye zvinhu
Hydroxyethyl cellulose hupfu
Mvura yakachena kana mvura yakasvibiswa
Midziyo yekubatisa (yakadai sekukuchidzira tsvimbo, magetsi emagetsi)
midziyo (yakadai segirazi, mabhakiti epurasitiki)
Zvekungwaririra
Shandisa mvura yakachena kana mvura yakasvibiswa kuti udzivise tsvina inokanganisa kuparara.
Hydroxyethyl cellulose inonzwa tembiricha, uye tembiricha yemvura inogona kugadziridzwa sezvinodiwa panguva yekunyungudika (mvura inotonhora kana nzira yemvura inodziya).
2. Nzira mbiri dzinowanzoshandiswa kuparara
(1) Nzira yemvura inotonhora
Paridza poda zvishoma nezvishoma: Mumudziyo uzere nemvura inotonhora, zvishoma nezvishoma uye zvakaenzanirana chimwaya HEC hupfu mumvura kudzivirira kuwedzera hupfu hwakawandisa panguva imwe chete kukonzera kukaka.
Kukuchidzira nekuparadzira: Shandisa chibatiso kumutsa nekumhanya kwakaderera kuparadzira hupfu mumvura kuita kumira. Agglomeration inogona kuitika panguva ino, asi usanetseka.
Kumira nekunyorova: Rega kupararira kumire kwemaawa 0.5-2 kuti hupfu hunyatsotora mvura nekuzvimba.
Ramba uchikurudzira: Shingairira kusvikira mhinduro yacho yakanyatsojeka kana isina granular kunzwa, iyo inowanzotora 20-40 maminitsi.
(2) Nzira yemvura inodziya (mvura inopisa pre-dispersion method)
Pre-kupararira: Wedzera zvishoma zveHEChupfu kusvika ku50-60 ℃ mvura inopisa uye kurumidzisa nekukasira kuiparadzira. Chenjerera kudzivirira hupfu agglomeration.
Dilution yemvura inotonhora: Mushure mekunge hupfu hwatanga kuparadzirwa, wedzera mvura inotonhora kuti inyungurudze kune yakanangwa uye simbisa panguva imwe chete kuti ikurumidze kuparara.
Kutonhodza uye kumira: Mirira kuti mhinduro itonhore uye umire kwenguva yakareba kuti HEC iparadze zvachose.
3. Makiyi ekugadzirisa maitiro
Dzivisa agglomeration: Kana uchiwedzera HEC, isase zvishoma nezvishoma uye ramba uchikurudzira. Kana maagglomerations awanikwa, shandisa sieve kuparadzira hupfu.
Dissolution tembiricha kutonga: Iyo nzira yemvura inotonhora yakakodzera mhinduro dzinoda kuchengetwa kwenguva yakareba, uye nzira yemvura inodziya inogona kupfupisa nguva yekunyungudika.
Nguva yekuparara: Inogona kushandiswa kana kujeka kwakazara kusvika kuhutano, izvo zvinowanzotora maminetsi makumi maviri kusvika maawa akawanda, zvichienderana nekutsanangurwa uye kuiswa kweHEC.
4. Zvinyorwa
Solution concentration: Kazhinji inodzorwa pakati pe0.5% -2%, uye iyo chaiyo yekumisikidza inogadziriswa zvinoenderana nezvinodiwa chaizvo.
Kuchengetedza uye kugadzikana: HEC mhinduro inofanirwa kuchengetwa mumudziyo wakavharwa kudzivirira kusvibiswa kana kuratidzwa kune yakakwirira tembiricha nharaunda inokanganisa kugadzikana kwayo.
Kuburikidza nematanho ari pamusoro,hydroxyethyl celluloseinogona kunyatsonyungudika mumvura kuti iite yunifomu uye yakajeka mhinduro, iyo yakakodzera kune dzakasiyana siyana dzekushandisa.
