Kufananidzwa kweFluid Kurasika Resistance Property yePolyanionic cellulose Yakagadzirwa neDough process uye Slurry process.

Polyanionic cellulose (PAC) ipolymer inonyungudika mumvura inotorwa kubva muselulosi uye inowanzoshandiswa sechinhu chinodhaka chekurasikirwa kwemvura mumidziyo yekuchera inoshandiswa mukutsvagisa oiri negasi. Nzira mbiri huru dzekugadzira PAC ndiyo nzira yehupfu uye slurry process. Heino kuenzanisa kweiyo fluid kurasikirwa kuramba pfuma yePAC inogadzirwa neaya maitiro maviri:

1. Dough process:
   • Nzira yekugadzira: Mukugadzira mukanyiwa, PAC inogadzirwa nekuita cellulose nealkali, senge sodium hydroxide, kugadzira alkaline cellulose mukanyiwa. Iyi mukanyiwa inobva yaitwa ne chloroacetic acid kuunza mapoka e-carboxymethyl pamusana we cellulose, zvichiita kuti PAC.
   • Particle Size: PAC inogadzirwa nekanyiwa process kazhinji ine yakakura particle size uye inogona kunge iine agglomerates kana aggregates ePAC particles.
   • Fluid Loss Resistance: PAC inogadzirwa nehupfu dhizaini inowanzo ratidza kunaka kwekurasikirwa kwemvura mumvura yekuchera. Nekudaro, iyo yakakura particle saizi uye kugona kuvepo kweagglomerates kunogona kukonzera kunonoka hydration uye kupararira mumvura-based yekuchera zvinwiwa, izvo zvinogona kukanganisa fluid kurasikirwa kudzora kuita, kunyanya mukupisa kwepamusoro uye kudzvinyirira kwakanyanya.
2. Slurry Process:
   • Nzira yekugadzira: Mukuita slurry, cellulose inotanga kuparadzirwa mumvura kuti iite slurry, iyo inozoitwa ne sodium hydroxide uye chloroacetic acid kuburitsa PAC zvakananga mumhinduro.
   • Particle Size: PAC inogadzirwa ne slurry process kazhinji ine diki diki saizi uye yakanyanya kufanana yakapararira mumhinduro kana ichienzaniswa nePAC inogadzirwa nehupfu.
   • Fluid Loss Resistance: PAC inogadzirwa ne slurry process inotaridza kuratidza yakanakisa kurasikirwa kwemvura kuramba mumvura yekuchera. Iyo diki diki saizi uye yunifomu yekupararira inokonzeresa kukurumidza hydration uye kupararira mumvura-based yekuchera zvinwiwa, zvichiita kuti kuve nekunatsiridza kurasikirwa kwemvura kutadza kuita, kunyanya mumamiriro ezvinhu akaoma ekuchera.

ese ari maviri PAC anogadzirwa nekukanyiwa maitiro uye PAC inogadzirwa ne slurry process inogona kupa inoshanda yekurasikirwa kwemvura kurasika mumvura yekuchera. Nekudaro, PAC inogadzirwa neiyo slurry process inogona kupa mamwe mabhenefiti, akadai sekukurumidza hydration uye kupararira, zvichitungamira kune yakakwidziridzwa kurasikirwa kwekudzora mashandiro ekuita, kunyanya munzvimbo dzepamusoro-tembiricha uye yakanyanya-kudzvanywa kwekuchera. Pakupedzisira, sarudzo pakati peidzi nzira mbiri dzekugadzira inogona kuenderana nezvinodiwa zvekuita, kutariswa kwemutengo, uye zvimwe zvinhu zvine chekuita nekudhirowa kwemvura yekuchera.
