Polyanionic cellulose

Polyanionic cellulose (PAC) inonyungudika nemvura inonyunguduka cellulose inowana kushandiswa kwakapararira mumaindasitiri akasiyana ekushandisa, kunyanya muindasitiri yekuchera oiri negasi. Heino mhedziso ye polyanionic cellulose:

1. Kuumbwa: Polyanionic cellulose inotorwa kubva kune cellulose, yakasikwa polymer inowanikwa mumiti, kuburikidza nekugadzirisa kemikari. Mapoka eCarboxymethyl anounzwa pane cellulose musana, achipa anionic (negatively charged) zvivakwa.

2. Kushanda:

• Viscosifier: PAC inonyanya kushandiswa seviscosifier mumvura-based drilling zvinwiwa. Inopa viscosity kumvura, ichivandudza kugona kwayo kumisa uye kutakura zvakacherwa zvakachekwa kumusoro.
• Fluid Loss Control: PAC inoumba keke rakatetepa, risingapindiki sefa pamadziro echibhorani, ichidzikisa kurasikirwa kwemvura mukuumbwa uye kuchengetedza kugadzikana kwetsime.
• Rheology Modifier: PAC inokanganisa maitiro ekuyerera uye rheological zvimiro zvezvinwiwa zvekuchera, inosimudzira kumiswa kwezvakaoma uye kuderedza kugadzirisa.

3. Zvikumbiro:

• Oiri neGasi Kuchera: PAC ndiyo yekuwedzera yakakosha mumvura-yakavakirwa kuchera zvinwiwa zvinoshandiswa mumafuta uye gasi kuongorora nekugadzira. Inobatsira kudzora viscosity, kurasikirwa kwemvura, uye rheology, kuve nechokwadi chekushanda kwakanaka kwekuchera uye kugadzikana kwetsime.
• Kuvaka: PAC inoshandiswa seyakakora uye yekuchengeta mvura mumiriri mune simende maumbirwo akadai semagrouts, slurries, uye madhaka anoshandiswa mukuvaka zvikumbiro.
• Pharmaceuticals: Mukugadzirwa kwemishonga, PAC inoshanda sebhainda, disintegrant, uye inodzorwa-kuburitsa mumiririri muhwendefa uye capsule maumbirwo.

4. Properties:

• Kunyungudika kweMvura: PAC inonyungudika zviri nyore mumvura, zvichiita kuti zvive nyore kuiswa mumasisitimu ane aqueous pasina kudiwa kwezvimwe zvinonyungudutsa kana zvinoparadzira.
• Kugadzikana Kwepamusoro: PAC inoratidza kugadzikana kwakanyanya kwekushisa uye kwemakemikari, kuchengetedza maitiro ayo ekuita pamusoro pehupamhi hwetembiricha uye pH mamiriro.
• Kushivirira Munyu: PAC inoratidza kugarisana kwakanaka nehuwandu hwemunyu uye mabrines anowanzo sangana munzvimbo dzemafuta.
• Biodegradability: PAC inotorwa kubva kune inodzokororwa chirimwa-based masosi uye ine biodegradable, zvichiita kuti ive nehushamwari.

5. Hunhu uye Zvinotsanangurwa:

• Zvigadzirwa zvePAC zvinowanikwa mumagiredhi akasiyana siyana uye maratidziro akarongedzerwa kune chaiwo maapplication uye kuita zvinodiwa.
• Matanho ekudzora emhando yepamusoro anovimbisa kuenderana uye kutevedzera mashandiro eindasitiri, kusanganisira API (American Petroleum Institute) zvakatemwa zvekuchera zvinwiwa zvinowedzera.

Muchidimbu, polyanionic cellulose inowandisa uye inoshanda zvakasiyana-siyana ine viscosifying, kudzora kurasikirwa kwemvura, uye rheological zvivakwa, zvichiita kuti ive yakakosha kune akasiyana maindasitiri ekushandisa, kunyanya muindasitiri yekuchera oiri uye gasi. Kuvimbika kwayo, kuita, uye kuenderana kwezvakatipoteredza kunobatsira pakushandiswa kwayo kwakapararira munzvimbo dzakaoma dzekuchera.
