Poly Anionic cellulose, PAC-LV, PAC-HV

Poly anionic cellulose (PAC) ipolmer inonyungudika nemvura inotorwa kubva muselulosi uye yakagadziridzwa nemapoka ecarboxymethyl. Inowana kushandiswa kwakakura mumaindasitiri akasiyana, kusanganisira kuchera mafuta, kuvaka, mishonga yemishonga, uye chikafu. PAC inowanikwa mune akasiyana viscosity mamakisi, ine PAC-LV (Low Viscosity) uye PAC-HV (High Viscosity) ari maviri akajairika akasiyana. Heino kupatsanurwa kweumwe neumwe:

1. Poly anionic Cellulose (PAC):
   • PAC ndeye cellulose inobva kune iyo inopa rheological properties kune aqueous mhinduro.
   • Inoshandiswa seviscosifier, fluid kurasikirwa control agent, uye rheology modifier mune dzakasiyana siyana dzekushandisa.
   • PAC inoshanda zvakanyanya mukudzora zvimisikidzo zvakaita seviscosity, kumiswa kwezvakaoma, uye kurasikirwa kwemvura, zvichiita kuti ive yakakosha mumaindasitiri akasiyana siyana.
2. PAC-LV (Low Viscosity):
   • PAC-LV igiredhi re polyanionic cellulose ine yakaderera viscosity.
   • Inowanzo shandiswa kana ine mwero viscosity uye kudzora kurasikirwa kwemvura kunodiwa mumashandisirwo akadai sekuchera mafuta, kuvaka, uye mishonga.
   • PAC-LV inopa viscosification uye fluid kurasikirwa kwekudzora zvivakwa uku ichichengetedza yakaderera viscosity ichienzaniswa nePAC-HV.
3. PAC-HV (High Viscosity):
   • PAC-HV igiredhi re polyanionic cellulose ine high viscosity.
   • Inoshandiswa kana yakakwira viscosity uye yakanakisa kurasikirwa kwemvura yekudzora inodiwa, kunyanya mukuda maapplication akadai seoiri uye gasi kuchera.
   • PAC-HV inonyanya kushanda mukuchengetedza kugadzikana kwetsime, kutakura kugona kwekuchekwa kwekucheka, uye kudzora kurasikirwa kwemvura mumamiriro ezvinhu akaoma ekuchera.

Applications:

• Oiri neGasi Kuchera: Ose PAC-LV uye PAC-HV akakosha ekuwedzera mumvura-yakavakirwa mvura yekuchera, inobatsira mukudzora viscosity, kurasikirwa kwemvura, uye rheology shanduko.
• Kuvaka: PAC-LV inogona kushandiswa seyakakora uye yekuchengeta mvura mumiriri mune simende maumbirwo akadai semagrouts, slurries, uye madhaka anoshandiswa mukuvaka zvikumbiro.
• Pharmaceuticals: PAC-LV uye PAC-HV inogona kushanda sevasungiri, disintegrants, uye inodzorwa-kuburitsa vamiririri muhwendefa uye capsule maumbirwo mumishonga.
• Indasitiri yeChikafu: PAC inoshandiswa seyakakora, inodzikamisa, uye emulsifier muzvigadzirwa zvekudya, ichipa magadzirirwo uye kuvandudza sherufu-hupenyu kugadzikana.

Muchidimbu, polyanionic cellulose mune ese ari maviri akaderera viscosity (PAC-LV) uye yakakwirira viscosity (PAC-HV) mamakisi anoita basa rakakosha mumaindasitiri akasiyana, achipa rheological control, viscosity modified, uye kurasikirwa kwemvura kurasikirwa zvivakwa zvinoenderana nezvinodiwa zvekushandisa.
