Maitiro Ekupararira HydroxytHyl Cellulose?

HydroxytHyl Cellulose (HEC) iri polymer yakashandiswa zvakanyanya mumuindasitiri akasiyana siyana nekuda kwezvinhu zvakasiyana-siyana zvakadai sekukora, nekuchengetwa kwemvura, uye kugona kwemvura. Kuparadzira hec nenzira yakakodzera kuve nechokwadi chekushandiswa kwayo zvinoshanda sekushandisa senge pendi, zino, mishonga, mishonga yemishonga, uye zvigadzirwa zvekuvaka.

1. Kunzwisisa hydroxyethyl cellulose (Hec):
Hec is is is is is is-ionic, yakadzika-mvura polymer yakatorwa kubva ku cellulose.
Iyo inoumba mhinduro dzakajeka mumvura, kuratidzira pseudoplastic maitiro, zvinoreva viscoity yayo inoderera nekuwedzera shear rate.

2. Kusarudzwa kweSolvent:
Mvura ndiyo yakajairika solvent yekuparadzira hec nekuda kwekunyanyisa kusimba.
Tembiricha uye pH yeSolvent inogona kupesvedzera kuvapararira kwehwanda. Kazhinji, kusarerekera kune zvishoma alkaline ph inosarudzwa.

3. Kugadzirira kuparadzira kwepakati:
Shandisa madhiri kana mvura yakadzvanywa kuti ideredze kusvibiswa kunogona kukanganisa hecperation.
Chengetedza tembiricha yaida yekunyungudika

4. Kupararira Maitiro:
a. Kusanganisa ruoko:
- Inokodzera zvidiki-zvidiki zvekushandisa.
- zvishoma nezvishoma wedzera hec poda kune solvent uchimutsa nguva dzose kuti udzivise kudzivisa.
- chengetedza kunyorova kwakanyorova kwehupfu usati wawedzera kusanganisa kusanganisa.

b. Mechanic Simudza:
-Shandisa chinwiwa chechina chakashongedzwa neine yakakodzera blade kana impeller.
- Gadzirisa kumhanyisa kumhanya kuti uwane yunifomu kupararira pasina kukonzera yakawandisa foam kana mhepo yekukurumidza.

c. Yakakwirira-Shear Kusanganisa:
- shandisa mitezo yakakwirira-inovhenganisa senge homogender kana yakakwira-kumhanya inovharidzira kuparadzaniswa kwakanaka.
- Dzora chiyero chiya yekudzivirira kudzivirira kusvibiswa kwemamorekuru eHec.

d. URTRAROSOPUREVEKI:
- Nyorera Ultrasonic simba kuputsa agglomerates uye kuwedzera kupararira.
- Optimize Samuhati paramita (frequency, simba, nguva) kuti udzivise kana kusvibiswa kwemhinduro.

5. Matipi ekubudirira kupararira:
Ita shuwa hec poda inowedzerwa zvishoma nezvishoma kudzivirira kuumbwa kweropa.
Dzivisa shanduko dzinongoerekana dzaita tembiricha kana pH panguva yekupararira, sezvavanogona kukanganisa her solubility.
Bvumira nguva yakakwana yekupedzisa hydration uye kupararira kweec zvidimbu.
Monitor viscosity panguva yekupararira kuzadzisa iyo inodiwa yekuenderana.
Shandisa zvigadzirwa zvakakodzera uye maitiro zvichienderana nehuwandu uye zvinodiwa zvekushandisa.

6. Hunhu Control:
Ita kuongorora kwekuona kune chero zvimedu zvevasina kusarudzwa kana maGel-kunge mafomu.
Kuyera viscosity uchishandisa viscometer kuti uone kusarudzika pamwe nezvinodiwa mazwi.
Mafambidzana nemiedzo yekuongorora kuti uongorore maitiro ekuyerera uye kugadzikana kwehwanda herparers.

7. Kuchengetera uye kubata:
Chengetedza HEC kupararira mumidziyo yakachena, yakasungwa yakasungwa zvekudzivirira kusvibiswa uye unyoro rinogona.
Ngwarira kuratidzwa kwenguva refu nekunyanyisa kupisa kana zuva rakananga zuva, iro rinogona kushatisa polymer.
Mabhonzo ane ruzivo rwakakodzera kusanganisira batch nhamba, kusangana, uye mamiriro ekuchengetedza.

8. Kuchengetedza Kufunga:
Tevedza nhungamiro dzekuchengetedza kana uchibata hupfu uye mhinduro.
Shandisa zvakakodzera zvekudzivirira pachako (ppe) senge magurovhosi uye mafambiro ekuchengetedza.
Dzivisa kufemerwa kweguruva zvimedu nekushanda munzvimbo ine mhepo-yakadzika kana kushandisa kuchengetedza kwekufema kana zvichidikanwa.
Kuparadzira hydroxylyl cellulose zvinobatsira zvinokwanisika zvinoda kunyatsofungisisa nezve solvent kusarudzwa, kudzikisira nzira, mhando dzekudzora matanho, uye kuchengetedza matanho ekuchengetedza. Nekutevera mirayiridzo iyi, iwe unogona kuve nechokwadi chekuita zvakakwana uye kugadzikana kweHEC kupararira mune dzakasiyana siyana maindasitiri.
