Polyanionic Cellulose (PAC)

Polyanionic Cellulose (PAC) chinhu chinobva mu cellulose chinonyungudika mumvura chinoshandiswa zvakanyanya mumaindasitiri akasiyana-siyana nekuda kwehunhu hwayo hwe rheological uye kugona kwayo kudzora kurasikirwa kwemvura. Chinobva mu cellulose yechisikigo kuburikidza nekuchinja kwakawanda kwemakemikari, zvichikonzera polymer ine anionic charges pamwe ne cellulose backbone. Heano mamwe mapoinzi akakosha nezve Polyanionic Cellulose:

1. Maumbirwo eKemikari: PAC yakafanana neselulosi asi ine mapoka eanionic carboxyl (-COO-) akabatana neseri yecellulose. Mapoka aya eanionic anopa PAC hunhu hwayo hwakasiyana, kusanganisira kunyungudika kwemvura uye kugona kudyidzana nemamwe mamorekuru kuburikidza nekubatana kwemagetsi.
2. Mashandiro: PAC inonyanya kushandiswa senzira yekugadzirisa rheology uye kudzora kurasikirwa kwemvura mukuchera mvura yekuongorora mafuta negasi. Inobatsira kudzora viscosity uye kuyerera kwemvura yekuchera, inovandudza kusungirirwa kwemvura yakasimba, uye inoderedza kurasikirwa kwemvura muzvikamu zvine maburi. PAC inowedzerawo kuchenesa maburi uye inodzivirira kusagadzikana kwezvitubu panguva yekuchera.
3. Mashandisirwo: Kushandiswa kukuru kwePAC kuri muindasitiri yemafuta negesi, uko kunoshandiswa mukugadzira madhaka ekuboora. Inowanzoshandiswa mukugadzira madhaka emvura nemafuta kuti iite kuti kuchera kushande zvakanaka uye kuve nechokwadi chekuti kuchera kunoshanda zvakanaka. PAC inoshandiswawo mune mamwe maindasitiri nekuda kwekukora kwayo, kugadzikana, uye hunhu hwekuchengetedza mvura mukugadzira kwakasiyana-siyana.
4. Mhando: PAC inowanikwa mumhando dzakasiyana uye kusviba kuti ienderane nezvinodiwa zvekushandisa. Mhando dzakajairika dzePAC dzinosanganisira magiredhi ekusviba akaderera ekudzora kurasikirwa kwemvura uye magiredhi ekusviba akakwirira ekugadzirisa kusviba uye kumisa zvinhu zvakasimba mumvura dzinosviba. Sarudzo yemhando yePAC inoenderana nezvinhu zvakaita semamiriro emvura, nzvimbo yekusviba, uye zvirevo zvemvura.
5. Zvakanakira: Kushandiswa kwePAC kune zvakanakira zvakawanda mumabasa ekuboora, zvinosanganisira:
   • Kudzora kurasikirwa kwemvura zvinobudirira kuchengetedza kugadzikana kwemugodhi uye kudzivirira kukuvara kwekuumbwa.
   • Kugadziriswa kwakavandudzwa kwezvidimbu zvemaboorerwo nesimbi dzakaoma, zvichiita kuti maburi acheneswe zviri nani.
   • Hunhu hwe rheological hwakavandudzwa, zvichiita kuti mvura ishande zvakanaka mumamiriro akasiyana-siyana ekudzika kwevhu.
   • Kuenderana nezvimwe zvinowedzerwa uye zvikamu zvemvura yekuboorera, zvichiita kuti zvive nyore kugadzirisa nekugadzirisa kugadzirwa kwayo.
6. Kufunga Nezvezvakatipoteredza: Kunyange zvazvo PAC ichishandiswa zvakanyanya mukuchera mvura, kukanganisa kwayo nharaunda uye kuora kwayo kunofanira kufungwa nezvako. Kuedza kuri kuitwa kugadzira dzimwe nzira dzisingakuvadzi nharaunda panzvimbo pePAC uye kuderedza kukanganiswa kwayo nenharaunda mukuchera.

Polyanionic Cellulose (PAC) chinhu chinoshandiswa pakugadzira mafuta negesi, uko chinoita basa guru mukuvandudza mashandiro emvura inocherwa uye kuona kuti kuchera kwacho kunoshanda zvakanaka. Hunhu hwayo hwakasiyana hwe rheological, kugona kwayo kudzora kurasikirwa kwemvura, uye kuenderana kwayo zvinoita kuti ive chinhu chakakosha mukugadzira madhaka ekucherwa.
