Ma cellulose a Poly Anionic, PAC-LV, PAC-HV

Poly anionic cellulose (PAC) ndi polima wosungunuka m'madzi wopangidwa kuchokera ku cellulose ndikusinthidwa ndi magulu a carboxymethyl. Amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana, kuphatikizapo kubowola mafuta, zomangamanga, zamankhwala, ndi zakudya. PAC imapezeka m'makalasi osiyanasiyana owoneka bwino, PAC-LV (Low Viscosity) ndi PAC-HV (High Viscosity) kukhala mitundu iwiri yofanana. Nayi chidule cha chilichonse:

  1. Ma cell anionic cellulose (PAC):
    • PAC ndi chochokera ku cellulose chomwe chimapereka ma rheological ku mayankho amadzi.
    • Amagwiritsidwa ntchito ngati viscosifier, wowongolera kutaya kwamadzimadzi, komanso rheology modifier pamagwiritsidwe osiyanasiyana.
    • PAC ndiyothandiza kwambiri pakuwongolera zinthu zamadzimadzi monga mamasukidwe akayendedwe, kuyimitsidwa kwa zolimba, komanso kutaya kwamadzimadzi, ndikupangitsa kuti ikhale yamtengo wapatali m'mafakitale osiyanasiyana.
  2. PAC-LV (Low Viscosity):
    • PAC-LV ndi kalasi ya polyanionic mapadi ndi otsika mamasukidwe akayendedwe.
    • Amagwiritsidwa ntchito ngati kukhuthala kocheperako komanso kuwongolera kutayika kwamadzimadzi kumafunikira pakugwiritsa ntchito monga kubowola mafuta, kumanga, ndi mankhwala.
    • PAC-LV imapereka viscosification ndi katundu wowongolera kutaya kwamadzi ndikusunga kukhuthala kochepa poyerekeza ndi PAC-HV.
  3. PAC-HV (Kuwoneka Kwambiri):
    • PAC-HV ndi kalasi ya polyanionic cellulose yokhala ndi kukhuthala kwakukulu.
    • Amagwiritsidwa ntchito ngati kukhuthala kwakukulu komanso kuwongolera bwino kwamadzimadzi kumafunika, makamaka pakugwiritsa ntchito movutikira monga kubowola mafuta ndi gasi.
    • PAC-HV ndiyothandiza makamaka posunga bata m'chitsime, kunyamula mphamvu zoboola, ndikuwongolera kutayika kwamadzimadzi pobowola zovuta.

Mapulogalamu:

  • Kubowola Mafuta ndi Gasi: Onse PAC-LV ndi PAC-HV ndi zowonjezera zofunika pamadzi obowola opangidwa ndi madzi, zomwe zimathandizira kuwongolera kukhuthala, kuwongolera kutaya kwamadzimadzi, komanso kusintha kwa rheology.
  • Zomangamanga: PAC-LV itha kugwiritsidwa ntchito ngati chokhuthala ndi kusunga madzi mumipangidwe ya simenti monga ma grouts, slurries, ndi matope omwe amagwiritsidwa ntchito pomanga.
  • Mankhwala: PAC-LV ndi PAC-HV amatha kugwira ntchito ngati zomangira, zosokoneza, komanso zotulutsa zoyendetsedwa ndi mapiritsi ndi makapisozi muzamankhwala.
  • Makampani a Chakudya: PAC imagwiritsidwa ntchito ngati thickener, stabilizer, ndi emulsifier muzakudya, kupereka mawonekedwe ndikuwongolera kukhazikika kwa moyo wa alumali.

Mwachidule, ma cellulose a polyanionic m'magiredi otsika kwambiri (PAC-LV) komanso ma viscosity apamwamba (PAC-HV) amagwira ntchito yofunika kwambiri m'mafakitale osiyanasiyana, kupereka kuwongolera, kusinthika kwamakasitomala, komanso kuwongolera kutayika kwamadzimadzi molingana ndi zofunikira za ntchito.
