Luhlobo luni lwePolymer yi-HPMC?

I-HydroxyPOpyl Methylcelcelsulose (i-HPMC) yinto eqhelekileyo ye-polymer kunye neselfowuni. Yi-polymer ye-ionic enganyikithi yamanzi eyenziwe ngokutshintsha i-shemilsulose yendalo. Inkqubo yokulungiselela i-HPMC ihlala ibandakanya la manyathelo alandelayo: I-Alkality selUlose yonyango lwe-Alkali, kwaye emva koko isebenze nge-proplene oxide kunye ne-propyl oxide kunye ne-prophelide phantsi kweemeko ze-Alkali ine-HPMC.

Isakhiwo sekhemikhali kunye neepropathi ze-HPMC
Iyunithi esisiseko ye-HPMC yi-β-d-pyranose glucose, ekwakwiyunithi esisisiseko se-selulose. Kwi-HPMC, amanye amaqela e-hydroxyl (--) athatyathelwa amaqela e-Macwitchy (-och₃) kunye ne-hydroxypropoxy amaqela (-och₂₂hhch₃), ke imeko yayo yahlukile kuleyo yeselsowese yendalo. Oku kubekwa endaweni ukuphucula ukubenzela i-HPMC emanzini kunye nezinyibilikisi ezithile zezinto eziphilayo, kwaye zinozinzo oluhle kunye nochungezo olusezantsi.

Xa i-HPMC ichithwe emanzini, inokwenza isisombululo esizinzileyo se-colloidal. I-sloubaz yayo inxulumene nohlobo kunye nenqanaba lokufakwa endaweni yendawo yokuhlala. Ngokubanzi, i-HPMC enemixholo ephezulu ye-methyl inabantu ababandayo emanzini abandayo, ngelixa i-HPMC enenqanaba eliphezulu le-hydropyl inabasebenzi abanobuchule. Ukongeza, izisombululo ze-HPMC zinezinto eziguqukayo ze-Thermoi, oko kukuthi, zinejele xa zishushu kwaye zinyibilike xa zipholile.

IZIXHOBO ZE-HPMC
Ngenxa yobume bayo obukhethekileyo kunye neepropathi ze-physochemical, i-HPMC isetyenziswe ngokubanzi kumasimi amaninzi.

Izinto zokwakha: Kwizinto zokwakha, i-HPMC ihlala isetyenziswa njenge-tickener kunye nearhente yokugcina amanzi ukuphucula ukusebenza kwesamente kunye ne-Gypsim esekwe kunye nomgangatho wemveliso yokugqibela. Ingaphucula i-obethes, ukunyangwa kunye nokuqina kodaka.

Iyeza: Ukusetyenziswa kwe-HPMC kwintsimi yamachiza ikakhulu kubandakanya ukukhululwa kwezinto ezilawulwayo, iigobolondo ze-capsule kunye neebhulethi zetafile. Kuba i-HPMC ayinatyhefu, ayicaphuki kwaye ineendawo ezilungileyo zokuzinza, isetyenziswa ngokubanzi kukukhululwa kunye nokulawulwa kwamalungelo okukhulula amacwecwe.

Ukutya: Kwishishini lokutya, i-HPMC isetyenziswa njenge-thickener, i-stabilizer kunye ne-mulsifier evelisweni, njenge-ice cream, i-jelly, njl. Njl.

I-cosmetics: kwicandelo le-cosmetics, i-HPMC ihlala isetyenziswa njenge-thickener ye-eulsions, iikhrim kunye ne-gels. Ayisinikanga kuphela ukwenziwa kwesinye, kodwa kukwayifilimu eqinisiweyo kumhlaba wolusu, ngaloo ndlela idlala inkolelo yokuthambisa kunye nokukhusela.

I-COARSSGS: I-HPMC isetyenziswa njenge-thi chuokener, isisasazi kunye ne-mulsifier kwi-paressings, enokuphucula ukusebenza kwengubo kunye nokuphucula umgangatho kunye ne-gloss yengubo.

Izibonelelo kunye nokusikelwa umda kwe-HPMC
I-HPMC ineengenelo ezininzi, ezinje ngomhlaba ofanelekileyo, uzinzo lwamachiza, ongenabuthathaka kunye ne-biomatise. Ezi mpawu zenze ukuba zisetyenziswe ngokubanzi kwiindawo ezininzi. Nangona kunjalo, i-HPMC nayo inemida ethile. Umzekelo, phantsi kwemeko yobushushu obuphezulu, i-vickosity ye-HPMC iya kuyehla kakhulu, enokuba yingxaki kwezinye iinkqubo. Ukongeza, i-HPMC inozinzo olugwenxa kwizisombululo ezigxile kwisotyisiseko, ekwakusasaze isicelo sayo kwezinye iindawo ezikhethekileyo.

I-HPMC yi-polymer ebalulekileyo esebenzayo. Ngeepropathi zayo ezizodwa zomzimba kunye nekhemikhali kunye nokusebenza kakuhle kwesicelo, kusetyenziswe ngokubanzi ekwakhiweni, amayeza, ukutya, i-cosmetics kunye neengubo. Nangona ineentsilelo ezithile, intsimi yesicelo ye-HPMC isandise ngophando oluqhubekayo nophuculo. Ngophuhliso lwesayensi kunye netekhnoloji, i-HPMC kulindeleke ukuba idlale indima ebalulekileyo kwimimandla evelayo.
