I-seluplose ehafu: Imveliso kunye nezicelo

Ukuveliswa kwe-Selese

Ukuveliswa kweI-seluplosekubandakanya ukuguqula i-pollyuli yendalo ngokwemichiza yokuphendula. Ezona ziqhelekileyo zibandakanya i-HydroxyPOpyl MethylcelceLcelse (i-HPMC), i-BMGMYMETHTLE (CMC), I-HMC), I-HMCYLETHTE Nantsi isishwankathelo ngokubanzi senkqubo yemveliso:

  1. Ukufunyanwa kwe-selselose:
    • Inkqubo iqala ngokufumana i-selsulose, ithathiwe ivela kwi-pulp okanye umqhaphu. Uhlobo lomthombo weselfowuni lunokuba nefuthe kwipropathi yemveliso yokugqibela ye-ete ye-ether.
  2. Ukutsala:
    • I-selsulose iphantsi kwenkqubo yokutsala ukuze iphule iintsinga zibe yifomu elilawulwayo.
  3. Ukucocwa:
    • I-seluplose ihlanjululwe ukuba isuse ukungcola kunye ne-LIGIN, kukhokelela kwizinto ezihlaziyiweyo zeSelese.
  4. Ukuphendula kwe-ether
    • Isisele esihlanjululwe yi-Etheristias, apho amaqela e-Ether (umzekelo, hydroxyyethl, i-HydroxyEthl, Cardroxymethy, Methyl, okanye i-Gothyl) izizwe ze-selly polymer chain.
    • I-Regeents efana ne-ithodane oxide, i-propylene oxide, i-sodium chirrocetate, okanye i-ceride ye-pheride isetyenziswa ngokusetyenziswa kwezi zinto.
  5. Ukulawulwa kweeparamitha zokuphendula:
    • Ukuphendula kwe-Etherication kulawulwa ngononophelo ngokweendlela zobushushu, uxinzelelo, kunye ne-PH yokufezekisa inqanaba elifunekayo lokufakelwa (DS) kwaye uphephe ukuphendula kwecala.
  6. Ukungathathi cala kunye nokuhlamba:
    • Emva kokuphendula kwe-etheriya, imveliso ihlala ingenakutsalwa ukuze isuse i-regegegents engaphezulu okanye iimveliso.
    • I-sellulose eguqulweyo ihlanjululwe ukuphelisa iikhemikhali zentsalela kunye nokungcola.
  7. Ukomisa:
    • I-ether selsulose ehlanjululwe i-Ether yomiswe ukuze ifumane imveliso yokugqibela kwi-powder okanye kwifom yegranular.
  8. Ulawulo lwemeko:
    • Iindlela ezahlukeneyo zohlalutyo, ezinjenge-nurglocal agonelic (i-NMR) i-SpecTroscopy, i-ft i-pir-rier-rier-gorier) ye-Spectroscopy, kunye neChromatography, ziqeshwa ukuhlalutya isakhiwo kunye neepropathi zeseluplose.
    • Inqanaba lokufakwa endaweni (DS) yiparameter ebalulekileyo elawulwa ngexesha lemveliso.
  9. Ukuqulunqwa kunye nokupakisha:
    • I-Seletulose Teltulose Teltulose Teltulose Teltulose Telwel yodweliswa kumabakala ahlukeneyo ukuhlangabezana neemfuno ezithile zezicelo ezahlukeneyo.
    • Iimveliso zokugqibela zipakishwe ukuze zisasazwe.

Izicelo zeSeluplose

I-Seleulose ehafu ifumana izicelo ezahlukileyo kumashishini aliqela ngenxa yepropathi yabo eyahlukileyo. Nazi ezinye iinkqubo eziqhelekileyo:

  1. Ishishini lokwakha:
    • I-HPMC: isetyenziswe kwiZicelo zodaka kunye nezicelo ezisekwe kwisamente yokugcina amanzi, ukusebenza, kunye nokuphuculwa okunamathelayo.
    • I-hec: iqashwe kwiTile Coheives, i-quages ​​edibeneyo, kwaye inikezela ngeepropathi zayo zokugcina amanzi kunye namanzi.
  2. Amayeza:
    • I-HPMC kunye ne-MC: isetyenziswe kwiifom zamayeza njengababhangisi, ii-sunters, kunye neearhente zokukhutshwa kwemali elawulayo.
    • I-EC: isetyenziswe kwimveliso yamayeza kwiitafile.
  3. Ishishini lokutya:
    • I-CMC: isebenza njenge-thi checker, i-stabilizer, kunye ne-mulsifier kwiimveliso ezahlukeneyo zokutya.
    • I-MC: isetyenziswe kwizicelo zokutya zepropathi yayo yokuthambisa kunye nokugcwala.
  4. Iipeyinti kunye neengubo:
    • I-Hec kunye ne-HPMC: Nika ulawulo lwe-viscosity kunye nokugcinwa kwamanzi kwinkqubo yepeyinti.
    • EC: Isetyenziswe kwi-caress yepropathi yayo yokwakha ifilimu.
  5. Iimveliso zoKhathalelo lobuqu:
    • I-Hec kunye ne-HPMC: ifunyenwe kwi-shampoos, i-lotions, kunye nezinye iimveliso zononophelo zobuqu zokuziqhelanisa nokuzinzisa.
    • I-CMC: isetyenziswe kwi-toothpaste yepropathi yayo emangalisayo.
  6. Izibalo:
    • I-CMC: isetyenziswe njengearhente ye-stice kwizicelo zendwangu ngenxa yokuqulunqa iifilimu kunye nembeko.
  7. Ishishini leoyile negesi:
    • I-CMC: iqeshwe ekuthandeni ulwelo lolawulo lwendalo kunye nokuncitshiswa kwelahleko yelahleko.
  8. Ishishini lePhepha:
    • I-CMC: isetyenziswe njengephepha lokufumana iphepha kunye nokubonisa iarhente yefilimu yefilimu kunye nezamayeza.
  9. Ababukeli:
    • I-CMC: isetyenziswe kwi-adhessivers kwizinto zayo zokugcina amanzi kunye nokugcina amanzi.

Ezi zicelo zibalaselisa ukungahambelani kwe-Selessese enina kunye nokukwazi kwabo ukuphucula iifomu ezahlukeneyo zemveliso kuwo onke amashishini eyahlukeneyo. Ukukhetha i-Ether Sether ixhomekeke kwiimfuno ezithile zesicelo kunye neepropathi eziyinqwenelekayo zemveliso yokugqibela.
