I-Hydroxypropyl Methylcelceltulose (HPMC) yinto ebalulekileyo enoluhlu olubanzi lwezicelo kumzi-mveliso wamachiza kunye namanye amashishini anjengokutya, amayeza nolwakhiwo. Ibango le-HPMC sele ikhula ngokuzinzileyo kwiminyaka eninzi ngenxa yepropathi yayo eyahlukileyo efana nokutyibilika, ukubopha, ukwenziwa kwefilimu kunye nokugcinwa kwamanzi. Kweli nqaku, siza kuthetha ngemveliso yemveliso ye-alkaline Lead ye-Hydroxypropyl Methylcelcelgalose (HPMC).
I-Alkali Leaching Indlela yemveliso ye-Hydroxylpyl Methylcelsele (i-HPMC) yinkqubo apho i-selpulose iqala khona nge-proplene oxide kunye ne-methyl chloride phambi kobukho buka-Alkali. Inkqubo yenzeka phantsi kobushushu, uxinzelelo kunye nexesha iimeko ezilawulwayo ze-HPMC eziphezulu.
Inyathelo lokuqala ekuveliseni i-HPMC lisebenzisa indlela yemveliso ye-alkaline le-alkali lilungiselelo lezinto ezibukhali zeSelew. I-seluplose ihlanjululwe okokuqala ngokususa nayiphi na into engcolileyo kwaye iguqulwe ibe yi-alkali selsulose ngonyango nge-alkali efana neSodium hydroxide. Eli nyathelo libalulekile kuba likhula ngokutsha kweselseese kunye ne-regentnts esetyenziswe kumanqanaba alandelayo.
I-Alkali Selelose iphathwa ngomxube we-propylene oxide kunye ne-methyl chloride phantsi kobushushu obulawulwayo kunye noxinzelelo. Ukuphendula phakathi kwe-Alkali Selese kunye neziphumo zeRegent kukhokelela ekumiselweni kwemveliso, ongumxube we-hydroxypropyl methylceluplose kunye nezinye iimveliso.
Umxube uhlanjwa, uhlatywe kwaye wahluma ukuze asuse ukungafezeki njengokuvuselelwa okungasebenziyo kunye neemveliso. Isisombululo esineziphumo emva koko sijongiwe kukuphazamiseka ukufumana imveliso ephezulu ye-HPMC.
I-Alkali Leaching Indlela yemveliso ye-HydroxyPOpyl Methylceltulose ineenzuzo ezininzi xa kuthelekiswa nezinye iindlela zemveliso ezinjenge-etheriya. Enye yezibonelelo kukuba yinkqubo enobuhlobo obuyingqongileyo. Ngokungafaniyo nezinye iinkqubo, indlela yokufumana i-Alkali Leaching ayisebenzisi izinyibilikisi ezingekalo ezinobungozi kwindalo kunye nempilo yabantu.
Olunye inzuzo yale ndlela kukuveliswa kweemveliso eziphezulu ze-HPMC eziphezulu. Iimeko ezihlaziyiweyo ezilawulwayo Qinisekisa ukuba imveliso yokugqibela ingumgangatho ongaguqukiyo kwaye ilungele iintlobo ezahlukeneyo zezicelo.
Ukusetyenziswa kwe-HPMC kumzi-mveliso wamayeza kubalulekile ekuvelisweni kweetafile, iicapbules kunye nezinye iifom zedosi. I-HPMC inokusetyenziswa njenge-binder, i-intercrant, iarhente yokuhamba, njl. Njl.
I-HPMC ikwasetyenziswa njenge-thi checker, i-emulsifier kunye nokuzinza kumzi-mveliso wokutya. Ukusetyenziswa kwe-HPMC kwiimveliso zokutya kuqinisekisa ukuthungwa okungaguqukiyo, i-viscosity kunye nomgangatho.
Kumzi-mveliso wokwakha, i-HPMC isetyenziswa njengesamente yesamente yokuphucula ukusebenza, ukugcinwa kwamanzi kunye nokugcinwa kwamanzi kunye neempawu zokwenza ububi besamente. Ukusetyenziswa kwe-HPMC kuqinisekisa ukuba iimveliso zokwakha zikumgangatho ophezulu kwaye zifezekise imigangatho efunekayo.
Isishwankathelo, i-Alkali Leaching Indlela yemveliso ye-Hydroxylpyl I-MethylcelXelose (HPMC) yinkqubo yokuvelisa iimveliso ezikumgangatho we-HPMCC kwaye isetyenziswa kwimizi-mveliso eyahlukeneyo njengamayeza, ukutya kunye nolwakhiwo. Ukusetyenziswa kwe-HPMC kwezi zicelo kuqinisekisa ukuba imveliso iphakathi kumgangatho ophezulu kwaye ifezekisa imigangatho eyimfuneko. Le ndlela yemveliso inobuhlobo obunobuhlobo kwaye ivelise imveliso ephezulu ye-HPMC ephezulu.
