Umahluko phakathi kwe-HPMC kunye ne-MC, Hec, CMC

I-HydroxyPOpyl Methylcelcelsele (i-HPMC) kunye nee-Declotives, kuquka i-methylcelculose (MC), i-HMC), i-HMC), kunye ne-HMCDYTHTE (i-HMC), isetyenziswa ngokubanzi kumashishini abaluleke kakhulu ekusebenzeni Ukusetyenziswa kumacandelo ahlukeneyo, ukusukela ukusuka kwiindawo zamayeza kunye nokutya kulwakhiwo kunye nokhathalelo lobuqu.

I-selsulose derivetives zibalulekile kumashishini amaninzi ngenxa yeepropathi zawo ezihambelanayo nezicelo. Phakathi kwezi zinto zigxothiweyo, hydroxypropyl Methylcelcelcelsulose (HPMC), Methylcelcelcellulose (MC), i-HCDROXCYETHTE

1. Izakhiwo:

Hydroxypropyl methylcelceltulose (HPMC):
I-HPMC ihambelane ukusuka kwi-sellulose ngokuguqulwa kweekhemikhali ezibandakanya ukufaka endaweni yamaqela e-hydroxyl nge-methyl kunye namaqela e-hydroxypropy. Inqanaba lokufakwa endaweni (DS) libonisa iipropathi zalo, kubandakanya i-viscosity kunye nokuluka. Isakhiwo sekhemikhali se-HPMC sibonisa iipropathi zokwenza ifilimu zefilimu kunye nobuchule bokugcina amanzi, zisenza ilungele izicelo ezahlukeneyo.

Methylcellulose (MC):
I-MC isuselwa kwiselpulose ngokufaka amaqela athabathelayo amaqela amaqela e-methyl. Ngokungafaniyo ne-HPMC, i-MC ingenazithuba ze-hydroxypropy. Iipropathi zayo ziphenjelelwa zizinto ezinje ngenqanaba lokufaka endaweni kunye nobunzima bemolekyuli. I-MC ibonisa ukugcinwa kwamanzi ahle kakhulu kunye neepropathi ezinkulu, zenza ukuba ibe lixabisekile kumashishini njengemigangatho yamayeza kunye nokutya.

I-HYDROXYETHyL seluplose (Hec):
I-hec idityaniswe ngu-Ethersulose ye-sellyuene oxide. Ukuqaliswa kwamaqela e-hydroxyyl kunika iipropathi ezizodwa ezinje ngempumelelo enkulu kunye ne-pseudoplastity. I-Hec isetyenziswa ngokubanzi kwiimveliso zononophelo, iipeyinti, kunye nemibhedesi ngenxa yokulawulwa kwe-gesiology yayo kunye nokwenza ifilimu.

I-Carboxymethyl Selelose (CMC):
I-CMC iveliswa ngokuphendula i-seluplose nge-chlorocetic acid okanye ityuwa yayo yesodium. Amaqela e-carboxymethyl azaziswa, ukuphucula iipropathi ezinje ngokubenzela amanzi, uVeksisity, kunye nozinzo. I-CMC ifumana izicelo zokutya, amayeza, kunye nokuqhuba ioyile ngenxa yokutyibilika kwayo, ukuzinza, kunye nokubopha iipropathi.

2.Properties:

I-Viskosity:
I-HPMC, i-MC, Hec, kunye ne-CMC ibonakalise amanqanaba otyhidiweyo kuxhomekeka kwizinto ezifana nenqanaba lokufakelwa, ubunzima bemolekyuli, kunye nokuxinana. Ngokubanzi, i-HPMC kunye ne-MC ibonelela ngolawulo oluphezulu lwe-viscosity lokuthelekiswa ne-HMC kunye ne-CMC, nge-hec ebonelela ngempumelelo enkulu ekuthandeni.

Ukugcinwa kwamanzi:
I-HPMC kunye mc inezakhono ezilungileyo zamanzi, ezibalulekileyo kwizicelo ezifuna ukugcinwa komswakama nokukhululwa ixesha elide. I-HEC ikwabonisa iipropathi ezifanelekileyo zokugcina amanzi, ngelixa i-CMC ibonelela ngokugcinwa kwamanzi okulinganisela ngenxa yokuluka kwayo.

Imo yefilimu:
I-HPMC kunye ne-HEC yaziwa ngokuba nobuchule bokwenza ifilimu, inika amandla okuphuhliswa kweefilimu ezihambelanayo neziguquguqukayo. I-MC, nangona ikwazi ukwenza iifilimu, zinokukubonisa ukuba brittletlestlestlestletletletlet kunye ne-HEC. I-CMC, ngokuyintloko isetyenziswa njenge-arhente yokuthambisa kunye nokuzinzisa, ineepropathi ezilinganiselweyo zefilimu.

Umoya wobuchule:
Zonke izinto ezine zeselsulose zinyibilikiswe ngamanzi ukuya kwi-vering marnting. I-HPMC, i-MC, kunye ne-CMC inyibilikisa ngokulula emanzini, ngelixa i-HCC ibonakalisa ukuzoma komhlaba, efuna ubushushu obuphezulu bokutshitshiswa. Ukongeza, inqanaba lokufaka endaweni liyiphembelela ukususwa kwezi zinto zigxothiweyo.

3. Iindlela zokusebenzisa:

Amayeza:
I-HPMC kunye ne-MC isetyenziswa ngokufanelekileyo kwiifomu zamayeza njengababhangisi, i-ventergraby, kunye neearhente zokukhutshwa kwe-biorporative ngenxa yepropathi yokukhutshwa kwazo kunye nepropathi yokukhutshwa kwayo. I-HEC ifumana izicelo kwiZisombululo ze-Ophthalmic kunye neefomu eziphezulu ngenxa yokucacisa kunye nolawulo lwe-viscosity. I-CMC iqeshelwe ukumiselwa komlomo kunye neetafile zokuzithandela kunye nokuzinzisayo.

Ishishini lokutya:
I-CMC idlala indima ebalulekileyo kumzi-mveliso wokutya njenge-gickener, i-stabilizer, kunye ne-Statred ye-ice cream kwiimveliso ezinjenge-ice cream, iisosi, kunye nezinto ezibhakayo. I-HPMC kunye ne-MC isetyenziswa ekwenzeni ukutya kwabo ngokutyibilika kwabo, ukugcwala, kunye neepropathi zokubopha amanzi. I-hec ingaqhelekanga kodwa inokusetyenziswa kwizicelo ezikhethekileyo ezifana nokutya okuphantsi kunye neziselo.

Ulwakhiwo:
I-HPMC iqashwe ngokubanzi kwizixhobo zokwakha ezifana nokufakwa kwesamente, imifula ye-tile, kunye neemveliso ezisesikweni, kunye neemveliso ezisesikweni ngenxa yokugcinwa kwamanzi, ukuphuculwa kwemisebenzi, kunye nokunamathela. I-MC ikwasetyenziswa kwizicelo ezifanayo, igalelo ekuphuculeni ukungqinelana kunye nokudibana. I-HEC ifumana ukusetyenziswa okunqalwayo kulwakhiwo ngenxa yendleko zalo eziphezulu xa kuthelekiswa ne-HPMC kunye ne-MC.

Iimveliso zoKhathalelo lobuqu:
I-HEC kunye ne-HPMC zixhaphake kwiimveliso zobuqu njengeziqhwithi, i-lotions, kunye nee-croms njengeiarhente zokubambisa, izilo zokuzinza, kunye ne-Fiblers. Ukuhambelana kwazo kunye noluhlu olubanzi lwezithako ze-cosmetic kunye nokukwazi kwabo ukuphucula ukusebenza kwemveliso kwenza ukuba bazixabiseki kwimisebenzi. I-CMC inokusetyenziswa kwizicelo ze-niche kwishishini lokhathalelo lobuqu ngenxa yokuziqhelanisa nokuzinza kwayo kunye nezinto ezinkulu.

Inokubaluleka:
Ukubaluleka kwe-HPMC kunye neendawo zayo zilele kubuninzi bezinto ezininzi kunye nokuziqhelanisa namashishini ahlukeneyo. Ezi zinto ziphuculiweyo seselfowuni zisebenza njengezinto ezibalulekileyo ekwenzeni, zinegalelo kumgangatho wemveliso, ukusebenza kunye nokusebenza. Iipropathi ezahlukeneyo zenza ukuba zibe nokungabinakho ukubaluleka kumacandelo anje ngamayeza, ukutya, ukwakhiwa, kunye nokhathalelo lomntu, ukuqhuba nokukhula kwentengiso.

I-HYDROXYPOPLL Methylcelcelsulose (HPMC) kunye nee-Deverselcellulose (MC), i-HCDROXYETHTE (HMC), Nika iipropathi ezizodwa kunye nokusebenza ezilungele uluhlu olubanzi lwezicelo. Ngelixa ezi zinto zeselselose zaya kwimvelaphi yesiko ngokubhekisele kwimvelaphi yemichiza kunye nokubenzela amanzi, babonisa iimpawu ezahlukeneyo ngokwendlela yokufakelwa, ukugcinwa kwamanzi, kunye nokuluka. Ukuqonda lo mahluko kubalulekile ekuphenduleni ukusetyenziswa kwazo kumashishini, ukuqalisa kongeza, nokukhula koqoqosho ngokuqhuba.
