I-HPMC iphucula njani ukugcinwa kwamanzi?

I-HydroxyPOpyl Methylcelcellulose (HPMC) yi-Ionic ye-Ionic Seleclose enesicelo esibalulekileyo kumashishini ahlukeneyo, ngokuyintloko ngenxa yepropathi ekhethekileyo yokugcina amanzi. Olu phawu lubaluleke kakhulu ekuphuculeni intsebenzo kunye nomgangatho weemveliso kumacandelo anjengokwakha, amayeza, ukutya, kunye nokhathalelo lobuqu. Ukuqonda ukuba i-HPMC iphucula njani ukugcinwa kwamanzi kubandakanya ukuvavanya ubume bayo bemichiza, indlela yesenzo, kunye nezicelo ezithile ezahlukeneyo.

Isakhiwo sekhemikhali kunye neepropathi ze-HPMC
I-HPMC isuselwa kwi-seluplose, owona mkhulu we-polymer eninzi emhlabeni. Kutshiwe kakuhle ukubandakanya i-hydroxypropy kunye namaqela e-methyl, ephucula ukubenzela amandla kunye nokusebenza kwayo. Isakhiwo esiphambili se-HPMC siqukethe i-selllose yeselfowuni kunye namaqela e-hydroxyl ezifakwe endaweni ye-APEXY (-OCH3) kunye ne-hydroxypropy (-C2chohch3) amaqela. Olu hlengahlengiso lubonisa ukuluka kwamanzi kunye neepropathi ze-thermo-groberties, eziyimfuneko kulwabiwo lwalo lokugcina amanzi.

Indlela yokugcina amanzi
Imo ye-hydrophilic
I-hydroxyl, i-Mackesxy, kunye namaqela e-hydroxypropy kwi-HPMC i-hydrophilic. Oku kuthetha ukuba batsalela kwaye banxibelelana neemolekyuli zamanzi nge-hydrogen. Xa i-HPMC ixutywe namanzi, yenza isisombululo se-viscous okanye ijeli, kuxhomekeka kuxinzelelo. Amaqela e-hydrophili abambelela kwiimolekyuli zamanzi ngokuqinileyo, ukunciphisa izinga lokuphuma kwamanzi kunye nelahleko yamanzi kwinkqubo.

Ukuphuculwa kwe-viscosity
I-HPMC inyusa ukubonakala kwezisombululo ezinamandla nokuba zigxile kakhulu. Lo viscosity ephezulu uyacotha ukuhamba kweemolekyuli zamanzi, ukunciphisa ngokufanelekileyo ireyithi apho amanzi angasinda khona. Kwizinto zokwakha njengesamente kunye nodaka, i-viscosity eyandisiweyo inceda ukugcina amanzi ngaphakathi komxube onde, obaluleke kakhulu kunyango olufanelekileyo kunye namandla.

Imo yefilimu
I-HPMC inokwenza ifilimu eguqukayo, eqhubekayo xa yomile. Le filimu isebenza njengesithintelo kwilahleko yamanzi, ukurhweba ngemveliso. Kwizicelo ezinjengeengubo, imihlambi, kunye neetafile zamachiza, ukubanakho kwefilimu ekwakukwenza ifilimu kubalulekile ukugcina umxholo wokufuma ofunekayo ngokuhamba kwexesha.

Izicelo ze-HPMC kwimizi-mveliso eyahlukeneyo
Ishishini lokwakha
