Yintoni hypromellose eyenziwe?

I-Hypromellose, ekwabizwa ngokuba yi-hydroxypropyl methylcelcelculose (i-HPMC), yi-seslynthetic polymer ethathwe kwi-selulose esuka kwi-sellulose esuka kwi-sellyulose, eyi-Polymer yendalo efumaneka kwiindonga zeseli. Nantsi indlela yenziwa ngayo i-hypromellose:

1. Ukufunyanwa kwe-Selsulose: Inkqubo iqala ngokufumana i-selsulose efuzisiweyo, enokufumaneka kwimithombo yolwazi eyahlukeneyo efana ne-Pulp Pulp, iintsinga zekotoni, okanye ezinye izityalo ezinamaqhina. I-seluplose idla ngokukhutshwa kule mithombo ngothotho lweenkqubo zekhemikhali kunye noomatshini bokufumana izinto zesekofi.
2. Isiseko: Isisele esihlanjululwe phantsi kwenkqubo yokuhlengahlengiswa kwekhemikhali ebizwa ngokuba yi-etheriya, apho i-hydroxypropy ye-hydropyl kunye namaqela e-methyl izizwe zaziswa kwi-SellXose. Olu hlengahlengiso lufezekisiwe ngokuphendula kwiseluplose nge-proplone oxide (ukwazisa i-hydroxypropy) kunye ne-methyl chloride (ukwazisa amaqela e-methyl) phantsi kweemeko ezilawulwayo.
3. Ukuhlanjululwa kunye nokuSebenza: Emva kwe-Etherhesition, imveliso yesiphumo ihlambulukuqa ukucoca ukususa ukungafezekisi kunye neemveliso ezivela kwimpendulo. I-hypromellose ihlanjululwe yenziwa kwiifom ezahlukeneyo ezinjengeepuwuti, iigram, okanye izisombululo, kuxhomekeke kwisicelo sayo.
4. Ulawulo loMgangatho: Ngalo lonke inkqubo yokuphuhlisa, amanyathelo olawulo esemgangathweni amiliselwe ukuqinisekisa ubunyulu, ukungangqinelani, kunye nokusebenza kwemveliso ye-hypromellose. Oku kubandakanya uvavanyo lweeparamitha ezinje ngobunzima bemolekyuli, i-viscosity, ukuluka, kunye nezinye iipropathi zomzimba.
5. Ukupakishwa kunye nokuhanjiswa: Nje ukuba imveliso ye-hypromellose ihlangabezane nemigangatho yomgangatho, ipakishwe kwizitya ezifanelekileyo kwaye ihanjiswa kumashishini ahlukeneyo okusetyenziswa kwiindawo zamayeza, iimveliso zokutya, kunye nezinye iinkqubo.

Ngokubanzi, i-hypromellose yenziwa ngothotho lwezinto ezilawulwayo zekhemikhali kunye namanyathelo okucoca asetyenziswa kwi-seluplose, ekhokelela kwi-polymer esetyenziswe enesitayile kunye nezicelo ezahlukileyo kwimizi-mveliso eyahlukeneyo.
