Maitiro eSodium Carboxymethylcellulose/ Polyanionic cellulose

Sodium carboxymethylcellulose (CMC) uye polyanionic cellulose (PAC) zvinhu zvinobva mu cellulose zvinoshandiswa zvakanyanya mumaindasitiri akasiyana-siyana, kusanganisira chikafu, mishonga, zvizoro, uye kuchera mafuta. Zvinhu izvi zvinowanzo tevedzera mitemo chaiyo kuti zvive nechokwadi chekuti mashandisirwo azvo akanaka, akachengeteka, uye akafanana. Heano mamwe maitiro anowanzo shandiswa e sodium carboxymethylcellulose uye polyanionic cellulose:

Sodium Carboxymethylcellulose (CMC):

1. Indasitiri yezvekudya:
   • E466: Iyi ndiyo nzira yepasi rose yekuverenga nhamba dzezvinowedzera zvekudya, uye CMC yakapihwa nhamba E E466 neCodex Alimentarius Commission.
   • ISO 7885: Iyi ISO standard inopa matsananguriro eCMC inoshandiswa muzvigadzirwa zvekudya, kusanganisira zvinodiwa pakuchena uye hunhu hwemuviri.
2. Indasitiri yeMishonga:
   • USP/NF: Sangano reUnited States Pharmacopeia/National Formulary (USP/NF) rinosanganisira mifananidzo yeCMC, richitsanangura hunhu hwayo, zvinodiwa pakuchena, uye nzira dzekuyedza mashandisirwo emishonga.
   • EP: European Pharmacopoeia (EP) inosanganisirawo mifananidzo yeCMC, ichitsanangura mwero wayo wehunhu uye zvirevo zvekushandiswa kwemishonga.

Polyanionic Cellulose (PAC):

1. Indasitiri yeKuchera Oiri:
   • API Spec 13A: Tsanangudzo iyi yakapihwa neAmerican Petroleum Institute (API) inopa zvinodiwa zve polyanionic cellulose inoshandiswa sechinowedzera mvura yekuboorera. Inosanganisira tsanangudzo dzekuchena, kugoverwa kwehukuru hwezvinhu, hunhu hwerheological, uye kudzora kusefa.
   • OCMA DF-CP-7: Mutemo uyu, wakaburitswa neOil Companies Materials Association (OCMA), unopa gwara rekuongorora polyanionic cellulose inoshandiswa mukushandisa kuchera mafuta.

Mhedziso:

Mitemo ine basa rakakosha pakuona kuti sodium carboxymethylcellulose (CMC) nepolyanionic cellulose (PAC) zviri mumhando yepamusoro, zvakachengeteka, uye zvinoshanda mumaindasitiri akasiyana-siyana. Kutevedzera mitemo yakakodzera kunobatsira vagadziri nevashandisi kuchengetedza kuenderana uye kuvimbika muzvigadzirwa zvavo nemashandisirwo azvo. Zvakakosha kutarisa mitemo chaiyo inoshanda pakushandiswa kwakagadzirirwa CMC nePAC kuti uve nechokwadi chekudzora mhando uye kutevedzera mitemo.
