Itekhnoloji ye-seluplose

Itekhnoloji yeI-seluplosekubandakanya ukuguqulwa kweselphulelo, i-polymer yendalo ethathwe kwiindonga zeseli zezityalo, ukuvelisa ubume bepropathi kunye nemisebenzi. Ezona ziqhelekileyo zibandakanya i-HydroxyPOpyl MethylcelceLcelse (i-HPMC), i-BMGMYMETHTLE (CMC), I-HMC), I-HMCYLETHTE Nalu ke isishwankathelo setekhnoloji esetyenzisiweyo kwimveliso ye-seluplose

1. Impahla engekasilwa:
   • Umthombo weSeluplose: Isixhobo esiphambili seSpeyinti seSelecelose Ethen yi-SelelUlose, efunyenwe kwi-pulpulose, efunyanwa kwi-Pulp yeWood okanye umqhaphu. Umthombo we-seluplose uchaphazela iipropathi zemveliso yokugqibela ye-ether.
2. Ukulungiswa kwe-seluplose:
   • Ukutsala: I-Pulp yeWood okanye i-cotton iphantsi kwenkqubo yokutsala ukuze iphule iintsinga zeselselose kwifomu elilawulekayo.
   • Ukucocwa: Iseli ihlanjululwe ukuba isuse ukungcola kunye ne-LIGIN, kukhokelela kwinto ehlanjululwe iseko.
3. Ukulungiswa kweekhemikhali:
   • Ukuphendula kwe-etheriyali Oku kubandakanya ukuqalisa amaqela e-Ether (umzekelo, i-HydroxyEzyl, hydroxypropy, i-carboxymethyl, methyl, okanye i-ithyl) ukuya kumaqela e-cleymer kwi-cleymer chain.
   • Ukukhetha iiRegents: I-Regegents efana ne-ithoylene oxide, i-propylene oxide, i-sodium chlorocetate, okanye i-proloride isetyenziswa ngokusetyenziswa kwezi zinto.
4. Ukulawulwa kweeparamitha zokuphendula:
   • Iqondo lobushushu kunye noxinzelelo: Ukuphendula kwe-etherhesition kuqhutywa phantsi kobushushu obulawulwayo kunye neemeko zoxinzelelo ukufezekisa inqanaba elifunayo lokufakelwa (DS) kwaye uphephe ukuphendula kwecala.
   • Iimeko ze-Alkaline: Ukuphendula kwe-estition ezininzi zenziwa phantsi kweemeko ze-Alkaline, kwaye i-PH yomxube wokuphendula ijongwa ngononophelo.
5. Ukucocwa:
   • Ukungathathi cala: Emva kokuphendula kwe-Etheriya, imveliso ihlala ingenakuphela ukuze isuse imali egqithisileyo okanye iimveliso.
   • Ukuhlamba: I-selupese eguqulweyo ihlanjululwe ukuphelisa iikhemikhali zentsalela kunye nokungcola.
6. Ukomisa:
   • I-ether selsulose ehlanjululwe i-Ether yomiswe ukuze ifumane imveliso yokugqibela kwi-powder okanye kwifom yegranular.
7. Ulawulo lwemeko:
   • Uhlalutyo: Iindlela ezahlukeneyo zohlalutyo, ezinjenge-nuclener realnic (i-NMR) i-Spectrascopy, i-FTRE-GREIRE-GORTERT (i-FTRE) ye-Spectroscopy, kunye ne-ftrmier-ft i-Spectroscopy, kunye neChromatography, zisetyenzisiwe ukuhlalutya isakhiwo se-seluplose.
   • Isidanga sokufakwa endaweni
8. Ukuqulunqwa kunye nokusetyenziswa:
   • Ifomu yokuphela komntu ngamnye: I-Selessese edade zinikezelwe kubasebenzisi bokuphela kumashishini ahlukeneyo, kubandakanya nolwakhiwo, amayeza, ukutya, ukhathalelo lobuqu, kunye neengubo.
   • Amabakala-amaBanga aThengi: Amanqanaba ahlukeneyo eLutulose esuka ekufezekiseni iimfuno ezithile zezicelo ezahlukeneyo.
9. Uphando kunye nezinto ezintsha:
   • Ukuphuculwa okuqhubekayo: Imisebenzi yoPhando kunye noPhuhliso igxile ekuphuculeni iinkqubo zemveliso, ekwandiseni intsebenzo ye-Selelose yooNqaku, kunye nokuhlola izicelo zeNoves.

Kubalulekile ukuba uqaphele ukuba itekhnoloji yokuvelisa i-selsulose ethile inokuthi ihluka ngokusekwe kwipropathi efunekayo kunye nokusetyenziswa. Utshintsho olulawulwayo lweselpulose ngokuphendula kwe-etheriyalition ivumela uluhlu olubanzi lweeselsulose enina, zibethelela kwimizi-mveliso eyahlukeneyo.
