Ukulungiswa kwe-Selese

Ukulungiswa kweI-seluplosekubandakanya ukuguqula imichiza eguqula i-polymer yemvelo ye-Polymer yeNdlu ye-Etherhest. Le nkqubo yazisa amaqela e-Ether kwiqela le-hydroxyl le-selseme ye-selsemer, ekhokelela ekumiselweni kweeseli ezineempawu ezizodwa. Ezona ziqhelekileyo zibandakanya i-HydroxyPOpyl MethylcelceLcelse (i-HPMC), i-BMGMYMETHTLE (CMC), I-HMC), I-HMCYLETHTE Nantsi isishwankathelo ngokubanzi senkqubo yokulungiselela:

1. Ukufunyanwa kwe-seluplose:

• Inkqubo iqala ngokufumana i-selsulose efuzisiweyo, efumaneka kwi-Pulp yeWood okanye umqhaphu. Ukukhetha komthombo weSeluplose kunokuphembelela iipropathi zemveliso yokugqibela ye-Ether ye-Ether.

2. Ukutsala:

• I-selsulose iphantsi kwenkqubo yokutsala ukuze iphule iintsinga zibe yifomu elilawulwayo. Oku kunokubandakanya iindlela zokuhamba ngoomatshini okanye iikhemikhali.

3. Ukucocwa:

• I-selsulose ihlanjululwe ukuba isuse ukungcola, i-LIGIN, kunye nezinye izinto ezingezizo zeselula. Eli nyathelo lokuCoca libalulekile ekufumaneni izinto ezisemgangathweni eziphezulu.

4. Ukuphendula kwe-etheristic

• I-selupese ehlanjululwe yi-Etheriyas, apho amaqela e-Eers aziswa khona kumaqela e-hydroxyl kwikhonkco leselsemer Polymer. Ukukhetha iarhente yokukhuthaza kunye neemeko zokuphendula kuxhomekeke kwimveliso ye-Ether enqwenelekayo.
• Iiarhente eziqhelekileyo ze-EFEER ezibandakanya i-englone oxide, i-propylene oxide, iSodium Chlorocetate, iMethyl Chloride, kunye nezinye.

5. Ukulawulwa kweeparamitha zokuphendula:

• Impendulo yokuphendula ilawulwa ngononophelo ngokweqondo lobushushu, uxinzelelo, kunye ne-PH yokufezekisa inqanaba elifunekayo lokufakelwa (DS) kwaye uphephe ukusabela kwecala.
• Iimeko ze-alkaline zihlala ziqeshwa, kwaye i-PH yomxube wokuphendula ijongiwe kakhulu.

6. Ukungathathi cala kunye nokuhlamba:

• Emva kokuphendula kwe-etheriya, imveliso ihlala ingenakutsalwa ukuze isuse i-regegegents engaphezulu okanye iimveliso. Eli nyathelo lilandelwa ngokuhlamba ngokucokisekileyo ukuphelisa iikhemikhali kunye nokungcola.

7. Ukomisa:

• Isisele esihlanjululwe kwaye sisongelwe ukuba sifumane imveliso yokugqibela ye-selsulose kwi-powder okanye kwifom yegranular.

8. Ulawulo loMgangatho:

• Iindlela ezahlukeneyo zohlalutyo zisetyenziswa kulawulo oluphawulayo, kubandakanya i-hignetic resinance (i-NMR) i-Spectrascopy, i-phrier-rier-i-infrad (fird) ye-Spectrascopy, kunye ne-chromatography.
• Inqanaba lokufakwa endaweni (DS) yiparamitha ebaluleke kakhulu esweni ngexesha lemveliso ukuqinisekisa ukungqinelana.

9. Ukuqulunqwa kunye nokupakisha:

• I-ElerUse Ether Itheutyushwe emva koko ilungiselelwe amabakala ahlukeneyo ukuze ifezekise iimfuno ezithile zezicelo ezahlukeneyo. Iimveliso zokugqibela zipakishwe ukuze zisasazwe.

Ukulungiswa kwe-Selese tal yinkqubo entsonkothileyo yekhemikhali efuna ukulawulwa ngononophelo kwiimeko zokuphendula ukufezekisa iipropathi eziyimfuneko. Ukugxila kwe-selupolose ebhutsi kuvumela ukusetyenziswa kwawo kuluhlu olubanzi lwezicelo kuwo onke amashishini, kubandakanya amayeza, ukutya, ukwakhiwa, nangaphezulu.
