Zviyero zveSodium Carboxymethylcellulose/ Polyanionic cellulose

Sodium carboxymethylcellulose (CMC) uye polyanionic cellulose (PAC) zvinhu zvinobva paselulosi zvinoshandiswa zvakanyanya mumaindasitiri akasiyana siyana, kusanganisira chikafu, mishonga, zvizorwa, uye kuchera mafuta. Izvi zvinhu zvinowanzo kuomerera kune chaiwo mwero kuti ive nechokwadi chemhando, chengetedzo, uye kuenderana mukushandisa kwavo. Heano mamwe anowanzo kutaurwa zviyero zve sodium carboxymethylcellulose uye polyanionic cellulose:

Sodium Carboxymethylcellulose (CMC):

1. Indasitiri yeChikafu:
   • E466: Iyi ndiyo yepasi rose manhamba system yezvinowedzera zvekudya, uye CMC inopihwa iyo E466 neCodex Alimentarius Commission.
   • ISO 7885: Iyi ISO chiyero inopa zvakatemwa zveCMC inoshandiswa muzvigadzirwa zvekudya, kusanganisira kuchena maitiro uye zvimiro zvemuviri.
2. Indasitiri yemishonga:
   • USP/NF: The United States Pharmacopeia/National Formulary (USP/NF) inosanganisira monographs yeCMC, ichitsanangura hunhu hwayo, kuchena zvinodiwa, uye nzira dzekuyedza dzekushandisa kwemishonga.
   • EP: Iyo European Pharmacopoeia (EP) inosanganisirawo monographs yeCMC, inodonongodza maitiro ayo emhando uye zvirevo zvekushandiswa kwemishonga.

Polyanionic Cellulose (PAC):

1. Indasitiri Yekuchera Oiri:
   • API Spec 13A: Iyi dhizaini yakapihwa neAmerican Petroleum Institute (API) inopa zvinodiwa zve polyanionic cellulose inoshandiswa seyekuchera mvura yekuwedzera. Inosanganisira zvakatemerwa kuchena, particle size kugovera, rheological properties, uye filtration control.
   • OCMA DF-CP-7: Iyi chiyero, yakaburitswa neOil Companies Materials Association (OCMA), inopa nhungamiro yekuongororwa kwe polyanionic cellulose inoshandiswa mukuchera mafuta.

Mhedziso:

Mayero anoita basa rakakosha mukuona kunaka, kuchengetedzeka, uye kuita kwe sodium carboxymethylcellulose (CMC) uye polyanionic cellulose (PAC) mumaindasitiri akasiyana. Kutevedzera zviyero zvinoenderana kunobatsira vagadziri nevashandisi kuchengetedza kuenderana uye kuvimbika mune zvigadzirwa nemashandisirwo avo. Izvo zvakakosha kuti utarise kune chaiwo mwero anoshanda kune yakanangwa kushandiswa kweCMC nePAC kuve nechokwadi chekutonga kwakanaka kwemhando uye kutevedza kwemitemo.
