Iimpawu ze-HPMC kunye nemisebenzi

I-HydroxyPOpyl Methylcelceltulose i-polymer ye-Polymer onesiseko esinemizi-mveliso eyahlukeneyo njengamayeza aphezulu njengamayeza ahlukeneyo kunye nemisebenzi yenza isithako esixabisekileyo kwiimveliso ezininzi. Nantsi ukuhlolwa kwe-HPMC:

1. Iimpawu ze-HPMC:

Isakhiwo sekhemikhali: I-HPMC isuselwa kwisellulose, i-polymer yendalo efumaneka kwizityalo. Idityaniswe ngokutshintsha kwe-chemose nge-propylene oxide kunye ne-methyl chloride. Inqanaba lokufakwa endaweni ye-hydroxypropy kunye namaqela e-AFEXYy amisela iipropathi zayo.

Ukunyibilika: I-HPMC inyibilikisa emanzini ngaphezulu koluhlu lobushushu olubanzi. Umobiba uxhomekeke kwinqanaba lokufakwa endaweni kunye nobunzima bemolekyuli yePolymer. Amanqanaba aphezulu okufaka endaweni yokwanda ukunyusa ukuzola kwamanzi.

I-Viscosity: i-HPMC ibonakalisa i-pseudoplastic okanye indlela yokuziphatha ye-shear, intsingiselo yokuba ukubonakala kwayo kuncipha uxinzelelo lwe-Shear. UVenkile weZisombululo ze-HPMC unokuhlengahlengiswa ngokuhlengahlengiswa kweeparamitha ezinje ngobunzima bemolekyuli, isidanga sokufaka kunye nokugxila.

Ukuqulunqwa kwefilimu: I-HPMC yeefom ezicacileyo neziguquguqukayo xa iphoswe kwisisombululo. Iipropati zefilimu zinokuguqulwa ngokuhlengahlengisa uxinzelelo lwe-polymer kunye nobukho beeplasitizezi.

Uzinzo lwe-therm: I-HPMC inozinzo oluhle lobushushu, kunye namaqondo obushushu ahlala ngaphezulu kwe-200 ° C. Oku kwenza ilungele iindlela ezahlukeneyo zokulungisa, kubandakanya ukunyibilika okushushu kunye nenaliti.

I-Hydrophibility: Ngenxa yendalo yayo ye-hydrophilic, i-HPMC inokufunxa kwaye igcine amanzi amakhulu. Le ndawo iluncedo kwizicelo ezinje ngokukhutshwa kweziyobisi kunye nearhente yokuthambisa kwiinkqubo ezinamandla.

Ukuhambelana: I-HPMC iyahambelana nezinye izinto ezahlukeneyo, kubandakanya ezinye iipolisi, iiplasitizeli, kunye nezithako zamachiza ezisebenzayo (APIS). Oku kuhambelana nokuvumela iinkqubo ezintsonkothileyo ukuba zenziwe ngeempawu ezizenziwe ngokwezifiso.

Iipropathi ezingezizo i-ionic: i-HPMC yi-polymer engeyiyo i-ionic, oko kuthetha ukuba ayiphathi nayiphi na intlawulo yombane. Le propati inciphisa unxibelelwano olunee-retages ezihlawuliswayo ekuqulunqweni nasekuphuculeni uzinzo lwayo kwisisombululo.

Imisebenzi ye-2.hpmc:

I-Binders: Kwimigaqo yetafile, i-HPMC isebenza njenge-binder, ikhuthaza ububi phakathi kwamasuntswana kunye nokwandisa amandla omatshini wecwecwe. Ikwanceda iitafile zibulala i-Intences.

Ifilimu yokudibana kwefilimu: i-HPMC isetyenziswa ngokubanzi njengearhente yolawulo lwefilimu kunye ne-capsules. Yenza iyunifomu, ukukhuba okhuselayo okuyimaski imaski kunye nevumba lechiza, iphucula uzinzo, kwaye iququzelele ukuginya.

Ukukhutshwa okuzinzileyo: I-HPMC inokusetyenziselwa ukulawula inqanaba lokukhupha amachiza kwiifom zethamo. Ngokuphathelele ukuba senze i-gel maketer, i-HPMC inokulibazisa ukukhutshwa ngamachiza kwaye unike iziphumo ezizinzileyo zonyango.

I-Viscosity Modifier: Kwiinkqubo ezikhutshelwe, i-HPMC isebenza njenge-viscofier okanye i-thickener. Inika indlela yokuhamba yokuhamba kwe-pseudoplastic, ukuphucula ukwenziwa kozinzo kunye nokusebenza kwesicelo sefomu lemimandla efana nekhrim, i-lotions kunye ne-gels.

Iarhente yokuNyala: I-HPMC isetyenziselwa ukuzinzisa ukumiswa kwamasuntswana angenayo kwifomu yolwelo. Ithintela ukulungisa ngokwandisa i-viscofity yenqanaba eliqhubekayo kunye nokuphucula ukusasazeka kwetyala.

I-Emoulsifier: Kwimisebenzi-emulsion, i-HPMC ihlala iluncedo phakathi kwezigaba zeoyile kunye namanzi, ukuthintela ukwahlulwa kwesigaba kunye nokutsalwa kwenqanaba. Iphucula uzinzo kunye nobomi beshelfu ye-outs kwimveliso enjengeekhrim, ezovimba kunye ne-lotions.

Imo ye-Hydrogel: I-HPMC inokwenza i-hydroguls xa ihlelo le-hydared, iyenza iluncedo ekunxibe iimpahla zenxeba, iilensi zonxibelelwano, kunye neenkqubo zokuhambisa iziyobisi. Ezi hydrogels zibonelela ngendawo enomswakama kwinkanyamba kwaye zinokulayishwa ngamachiza okuhanjiswa kwendawo.

Iarhente yokuthambisa: I-HPMC isetyenziswa njengearhente yokuthambisa kwiimveliso zokutya ezinje ngeesosi, ukunxiba kunye needessert. Inika i-curtir egudileyo kwaye iphucule intanda ngaphandle kokutshintsha i-flavound okanye umxholo wesondlo.

Izongezo zokwakha: Kumzi-mveliso wokwakha, i-HPMC isetyenziswa njenge-arhente yokugcina amanzi kwisifo esekwe kwisamente kunye neeplate. Iphucula ukusebenza, i-adhesion, kunye nokunciphisa ukuqhekeza ukuphuma kwamanzi okucotha amanzi.

Isimo sengqondo sokuguqula umphezulu: i-HPMC inokuguqula iipropathi ezingaphezulu kwamanzi aqinileyo anjengephepha, amabali kunye ne-ceramics. Iphucula ukuprinta, i-adhesion kunye neepropathi zomqobo zengubo kunye neefilimu.

I-HydroxypropyTolmethylcelcelcelcelcelcel Ukuqina kwayo, i-viscosity, ubuchule bokwenza ifilimu kunye nokuhambelana kwenza isithako esifanelekileyo kwizicelo ezininzi kumashishini. Ukusuka kwiicawa zamayeza ukuya ekwakheni, ukutya kwi-cosmetics, i-HPMC iyaqhubeka nokudlala indima ebalulekileyo ekuphuculeni intsebenzo yemveliso kunye nomgangatho. NjengoPhando kunye neTekhnoloji, ukutshintsha kokusetyenziswa kwe-HPMC kunokwanda ngakumbi, ukuqhuba ubuchule bokuqulunqwa koyilo kunye nophuhliso lwemveliso.
