Hydroxypropyl methylcelculose (hpmc)kwayeMethylcelsulose (MC)Zombini zombini i-selulose isetyenziswa ngokufuthi isetyenziswa kwimizi-mveliso eyahlukeneyo, kubandakanya amayeza, ukutya, i-cosmetics, kunye nolwakhiwo. Ngaphandle kokufana kwazo, ezi zinto zimbini zineepropathi ezahlukileyo zekhemikhali kunye nokusetyenziswa.
1. Isakhiwo sekhemikhali
Zombini i-HPMC kunye ne-MC zizi-seluploses, kodwa umahluko ophambili ulele kumaqela eekhemikhali eziqhotyoshelwe kwi-selsebone.
Methylcelsulose (MC): Oku kwenziwa yimitha ye-sellyulose. Kule nkqubo, amaqela e-methyl (-Ch3) aqhotyoshelwe kumaqela e-hydroxyl yeemolekyuli ezisellulose. Isidanga se-methyty siqhele ukwahluka phakathi kwe-20-30%, kuxhomekeka kwinqanaba le-MC, ephembelela isolula kunye nezinye iipropathi.
Hydroxypropyl methylcelculose (hpmc): I-kimbacell®hpmc yindawo enzima kakhulu. Ukongeza kwi-methyling, ikwahluthwa i-hydroxypropy. Amaqela e-hydroxypropyl Isidanga se-hydroxyprocytion kunye nenqanaba le-methym ye-HPMC linokwahluka kakhulu, elinika amabakala e-HPMC ngeempawu ezahlukeneyo.
| Inqaku | Methylcelsulose (MC) | Hydroxypropyl methylcelculose (hpmc) |
| Isakhiwo sekhemikhali | I-Methyling yeSeluplose | I-Methyling kunye ne-hydroxyyprocyploption yesellulose |
| Amaqela aSebenzayo | Amaqela e-methyl (-Ch3) | Amaqela e-methyl (-Ch3) + + i-hydroxypropy yeqela (-C2chohch3) |
| Inqanaba lokufakwa endaweni (DS) | I-20-30% ye-methyling | Ukuhluka, kunye ne-methyl kunye ne-hydroxyproption yamanqanaba aguqukayo |
2. Ukunyibilikisa
Ukuluka kwenye yezona zinto zibalulekileyo xa uthelekisa i-MC kunye ne-HPMC. Ukwahlulahlula zombini ezi zinto zisuselwayo zeselfowuni zixhomekeke kwinqanaba lokufakwa endaweni yokufaka endaweni yezinto.
Methylcelsulose (MC): I-MC inyibiliza emanzini ashushu kodwa iyenza ijeli ekupholeni. Esi sibonelelo sahlukileyo se-gells xa ishushu kwaye ibuyela kwimeko yolwelo ekuphoseni yenye yezona mpawu zibalulekileyo ze-MC. Ayinyibili emanzini abandayo, kodwa inyibilikiswa emanzini ashushu ngaphezulu komgangatho othile wobushushu (50-70 °), kwaye inkqubo yokuhlisela iguqukele.
Hydroxypropyl methylcelculose (hpmc): I-HPMC, kwelinye icala, inyibilika kumanzi obandayo ashushu. Oku kwenza ukuba kuguqulwe ngakumbi xa kuthelekiswa ne-MC. Ukunyibilisela i-HPMC kuphenjelelwa ngohlobo lokufaka endaweni (umyinge we-methyl ukuya kumaqela e-hydroxypropy) kunye nebakala lokubonisa. Iidigri eziphezulu zokufaka endaweni zithanda ukwenza i-HPMC inyibilikiswe emanzini kumaqondo obushushu asezantsi.
| Ukunyibilikisa | Methylcelsulose (MC) | Hydroxypropyl methylcelculose (hpmc) |
| Ukunyibilikisa emanzini | Inyibilikiswe ngamanzi ashushu (ukuhlanjwa ngokupholisa) | Inyibilikiswa kumanzi ashushu nabandayo |
| Ipropathi yeGep | Iifom zejeli ekupholeni | Ayifuni i-gel, ihlala inyibiliza kuwo onke amaqondo obushushu |
3. I-viscofity
UVenkile udlala indima ebalulekileyo kwizicelo ezininzi, ngakumbi kumashishini amayeza kunye nokutya.
Methylcelsulose (MC)I-viscosity ye-kimbacell ye-kimbacell®mc yezisombululo kukuxhomekeka kubushushu. UVeksiko unyuka xa ushushu, kwaye ubonakalisa intlekele yejezi. Iqondo lokufakwa endaweni ichaphazela i-viscofity, ngamanqanaba aphezulu okufaka endaweni yokonakalisa okuphezulu.
Hydroxypropyl methylcelculose (hpmc): I-HPMC ngokubanzi ineprofayile engaguqukiyo engaguqukiyo xa kuthelekiswa ne-MC. Uhlobo lwe-HPMC lukwaphenjelelwa ngumgangatho wokufaka endaweni, kodwa uhlala uzizinza kumaqondo obubanzi amaqondo obushushu. Ukongeza, i-HPMC inokulungelelaniswa ukuba i-vikossies eyahlukeneyo, ukusuka ezantsi ukuya phezulu, kuxhomekeka kwisicelo esicetywayo.
| I-viscofity | Methylcelsulose (MC) | Hydroxypropyl methylcelculose (hpmc) |
| Ukuziphatha kwe-Viscosity | Inyuka ngemfumba (ukuhlanjwa) | Uhlobo oluzinzileyo lwamaqondo obushushu ohlukeneyo |
| Ukulawulwa kwe-viscofity | Ukulawulwa okunqongopheleyo kwi-viscofity | Ulawulo olukhulu ngakumbi kwi-viscofity esekwe kwinqanaba lebakala kunye nenqanaba lokufaka endaweni |
4. Izicelo
Zombini i-MC kunye ne-HPMC zisetyenziswa kakhulu kwigumbi lokutya lwamayeza, kodwa iipropathi ze-cosmetics, kodwa iipropathi ezithile ezenza zilungele ukusetyenziswa kwezicelo ezithile.
Methylcelsulose (MC):
Amayeza: I-MC ihlala isetyenziswa njengendawo yokubhabha, ihlazo, kunye nearhente yokuhlalisa kwifomu yecwecwe ngenxa yeepropathi zayo zokuhluthwa. Ikwasetyenziswa kwifomu elawulwayo.
Ishishini lokutya: I-MC isetyenziswa njengendawo yokutya, i-enulsifier, kunye nokuzinzisa. Ipropathi yokwakha igesi ixabisekile ekwenzeni iimveliso ezinjenge-ice cream, impahla yesaladi, kunye neemveliso zokubhaka.
Cosmetics: I-MC isetyenziswa kwi-cosmetics yokuqina kwayo, ukuqina, kunye nokuzinzisa iipropathi kwiimveliso ezifana ne-outs, i-shampoos, kunye neekhrim.
Hydroxypropyl methylcelculose (hpmc):
Amayeza: I-HPMC isetyenziswe ngokubanzi njenge-Binder kunye ne-Arhente yokukhutshwa-elawulwayo kwifomu yecwecwe. Ikwasetyenziswa kwiZisombululo ze-Ophthalmic njengeoyile kunye neenkqubo ezisekwe kwijeli.
Ishishini lokutya: I-HPMC isetyenziswa kwi-banglen-yasimahla yokubhaka, njengoko kulingisa i-positity ye-gluten kwinhlama. Ikwasetyenziswa njenge-stibilizer kunye ne-emulsifier ngokutya okwahlukeneyo.
Ukwakhiwa: I-HPMC isetyenziswa njengesongezo kwisamente, udaka, kunye neetekeves. Iphucula ukusebenza ngokukuko, ukugcinwa kwamanzi, kunye nokunamathela.
| Isicelo | Methylcelsulose (MC) | Hydroxypropyl methylcelculose (hpmc) |
| Amayeza | I-Binder, i-irintebgraph, iarhente yokuhamba | I-Binder, ilawulwa-ukukhululwa, i-ophthalmic ilungisiwe |
| Ishishini lokutya | I-thickener, i-eulsifier, i-stibilizer | Ukubhaka kwe-gluten-free ukubhaka, i-stabilizer, i-emulsifier |

| Ukwakhiwa | Kunqabile ukusetyenziswa | Yongezwa kwisamente, udaka, amachaphaza |
5. Ezinye iipropathi
I-hygroscopicicity: I-HPMC ngokubanzi i-hygroscopic (enomtsalane wamanzi) kune-MC, eyenza iluncedo kwizicelo apho kufuneka khona umswakama.
Uzinzo lwe-thermal: I-MC idla ngokubonisa uzinzo lwe-thermal olungcono ngenxa yepropathi yakhe yokuhlutha. I-HPMC, ngelixa uzinzile kuluhlu lobushushu olubanzi, alunakubonelela ngefuthe lokuya kwelinye ilizwe kwi-MC.

Ngelixa zombiniI-HPMCkwayeMCNgaba izicelo zeselwese zinokupheliswa kokusetyenzwa kweesekelo, izakhiwo zabo ezahlukeneyo zekhemikhali kunye neepropathi zizenza zilungele ukusetyenziswa okwahlukileyo. I-MC ibaluleke ngokukodwa kwizicelo ezizuza kwipropathi yayo ye-HPM, ngelixa izithixo ze-HPMC zenza ukuba izithixo zangoku zaziguquguqukayo ziyenza kube ngaphaya kwamashishini, kubandakanya ukwenziwa kokutya kunye namayeza. Ukuqonda lo mahluko kuyanceda ekukhetheni izinto ezifanelekileyo kwizicelo ezithile.
