Imigangatho yeSodium Carboxymethylcellulose/ Polyanionic cellulose

I-sodium carboxymethylcellulose (CMC) kunye ne-polyanionic cellulose (PAC) ziphuma kwi-cellulose ezisetyenziswa ngokubanzi kumashishini ahlukeneyo, kuquka ukutya, amayeza, izinto zokuthambisa, kunye nokugrumba ioli. Ezi zixhobo zihlala zihambelana nemigangatho ethile ukuqinisekisa umgangatho, ukhuseleko, kunye nokuhambelana kwizicelo zabo. Nantsi eminye imigangatho eqhele ukubhekiselwa kuyo kwi-sodium carboxymethylcellulose kunye ne-polyanionic cellulose:

I-Sodium Carboxymethylcellulose (CMC):

1. Ishishini lokutya:
   • I-E466: Le yinkqubo yamazwe ngamazwe yokubala iinombolo zezongezo zokutya, kwaye i-CMC inikwe inombolo ye-E466 yiKhomishoni yeCodex Alimentarius.
   • I-ISO 7885: Lo mgangatho we-ISO ubonelela ngeenkcukacha ze-CMC ezisetyenziswa kwiimveliso zokutya, kubandakanya iindlela zokucoceka kunye neempawu zomzimba.
2. Umzi mveliso wamachiza:
   • I-USP/NF: I-United States Pharmacopeia/Ifomula yeSizwe (USP/NF) ibandakanya i-monographs ye-CMC, ichaza iimpawu zayo ezisemgangathweni, iimfuno zokucoceka, kunye neendlela zokuvavanya kwizicelo zamachiza.
   • I-EP: I-European Pharmacopoeia (EP) ikwabandakanya i-monographs ye-CMC, ichaza imigangatho yayo yomgangatho kunye neenkcukacha zokusetyenziswa kwamachiza.

Polyanionic Cellulose (PAC):

1. Umzi-mveliso woKwemba i-oyile:
   • I-API Spec 13A: Le nkcazo ekhutshwe yi-American Petroleum Institute (API) ibonelela ngeemfuno ze-polyanionic cellulose esetyenziswa njenge-drilling fluid additive. Ibandakanya iinkcukacha zokucoceka, ukuhanjiswa kobungakanani besuntswana, iimpawu zerheological, kunye nolawulo lokuhluza.
   • I-OCMA DF-CP-7: Lo mgangatho, opapashwe yi-Oil Companies Materials Association (OCMA), inika izikhokelo zokuvavanya i-polyanionic cellulose esetyenziswa kwizicelo zokugaya ioli.

Isiphelo:

Imigangatho idlala indima ebalulekileyo ekuqinisekiseni umgangatho, ukhuseleko, kunye nokusebenza kwe-sodium carboxymethylcellulose (CMC) kunye ne-polyanionic cellulose (PAC) kumashishini ahlukeneyo. Ukuthotyelwa kwemigangatho efanelekileyo kunceda abavelisi kunye nabasebenzisi bagcine ukuhambelana kunye nokuthembeka kwiimveliso zabo kunye nokusetyenziswa. Kubalulekile ukubhekisa kwimigangatho ethile esebenzayo kusetyenziso olucetywayo lweCMC kunye nePAC ukuqinisekisa ulawulo olululo lomgangatho kunye nokuthotyelwa kwemithetho.
