Ukuphuculwa kwe-hydroxyyl seluplose

Ukuphuculwa kweHydroxyyl seluplose(Hec) kubandakanya ukuqhubekeka kwezinto ezingafunekiyo ukuphucula ubunyulu bayo, ukungqinelana, kunye neepropathi zezicelo ezithile. Nantsi isishwankathelo senkqubo yokuphuculwa kwe-hec:

I-1. Ukukhetha izinto eziphathekayo:

Inkqubo yokuphucula iqala ngokukhethwa kweselsulose ekumgangatho ophezulu njengezixhobo eziluhlaza. I-seluplose inokufumaneka kwimithombo eyahlukeneyo, ezinjengeenkuni zenkuni, ii-cotton ze-cotton, okanye ezinye izinto ezisekwe kwizityalo.

2. Ukucocwa:

Izinto zeselfowuni eziluhlaza zeselfowuni zihlambulula ukucoca ukususa izinto ezinje nge-lign, i-hemicellulose, kunye nezinye izinto ezingezizo zeselula. Le nkqubo yokucoca idla ngokuhlamba, i-bleaching, kunye nonyango lwekhemicamicamicamicamicamicali yokuphucula ubunyulu besellulose.

I-3. Isivumelwano:

Emva kokucocwa, i-seluplose iguqulwe ngemichiza ngokwazisa i-emperchythyl kwi-selsulose i-selselose, ekhokelela ekuqulunqweni kwe-hydroxythl seluplose (hec). I-Etherication Reaction Peection Peetise ibandakanya ukusetyenziswa kwe-Alkali Metal Hydroxides kunye ne-Ethylene oxide okanye i-Ethlone Chlorohydrin.

4. Ukungathathi cala kunye nokuhlamba:

Ukulandela i-ethersication, umxube wokuphendula awunamacala afanelekileyo ukuze ususe ngaphezulu i-alkali kwaye ulungelelanise i-PH. Imveliso engathathi hlangothi ihlanjwe ngokucokisekileyo ukuze isuse iikhemikhali zentsalela kunye neemveliso ezivela kwimpendulo.

5. Ukuthoba kunye nokomisa:

Isisombululo se-HEC se-HEC siyasuswa ukuba sisuse nayiphi na isuntswana okanye ukungcola. Emva kokufakelwa, isisombululo se-HEC sinokugxininiswa, ukuba kukho imfuneko, kwaye somile ukuze sifumane i-powded ehleliweyo okanye i-hec ye-hec.

6. Ulawulo loMgangatho:

Ngayo yonke inkqubo yokuphuculwa, amanyathelo olawulo lomgangatho asetyenziswe ukuqinisekisa ukungqinelana, ubunyulu, kunye nokusebenza kwemveliso ye-hec. Iimvavanyo zoLawulo loMgangatho zinokubandakanya imilinganiselo yokufakelwa, uhlalutyo lwesimo semolekyuli, umxholo wokufuma wokuzimisela, kunye nohlalutyo lomzimba kunye neekhemikhali.

7. Ukupakisha kunye nokuGcina:

Nje ukuba ihlaziyiwe, imveliso yehek ipakishwe kwizitya ezifanelekileyo okanye iingxowa zokugcina nokuhamba. Ukupakishwa ngokufanelekileyo kuyanceda ukukhusela i-hec kungcoliseko, ukufuma, kunye nezinye izinto zokusingqongileyo ezinokuthi zichaphazele umgangatho wayo.

Izicelo:

I-hydroxyEtethyl seluplose (hec) ifumana izicelo ezininzi kumashishini ahlukeneyo, kubandakanya:

• Ulwakhiwo: Isetyenziswe njenge-thiicker, i-Rheoology Sheesifier, kunye neArhente yokugcina amanzi kwiimveliso ezisekwe kwisamente, iipende, iipayiti, kunye nemikhono.
• Inkathalo yobuqu kunye ne-cosmetics: isetyenziswa njenge-tickener, i-stabilizer, kunye nefilimu yangaphambili echibini, iikhrim, ii-shampoos, kunye nezinye iimveliso zononophelo.
• Amayeza: Isetyenziswe njenge-binder, i-istirgran, kunye ne-Arhente yokukhutshwa-elawula iitafile zamachiza asemachiza, i-capsules, kunye nokumiswa komlomo.
• Ukutya: Ukuqeshwa njenge-thi chulener, i-enulssifier, kunye nokuzinza kwiimveliso zokutya ezinje ngeesosi, ukunxiba, kunye neemveliso zobisi.

ISIQINISEKISO:

Ukuphuculwa kwe-hydroxyEtheethyl seluplose (hec) kubandakanya amanyathelo aliqela ukucoca kunye nokuguqula i-row selseses, i-polymer yokusebenza ngokudibeneyo kunye ne-polymer equlunqwa kwizinto ezifana nokwakha, ukhathalelo lobuqu, kunye nokutya. Inkqubo yokuphucula iqinisekisa ukungaguquguquki, ubunyulu, kunye nomgangatho wemveliso yehek, evumela ukusetyenziswa kwayo ngeendlela ezahlukeneyo kunye neemveliso.
