Hydroxypropyl methylcelculose (hpmc)Ngaba i-ionic se-ionsulose i-ete isetyenziswe ngokubanzi kwizinto zokwakha, amayeza, ukutya, izixhobo zokuthambisa kunye nezinye izinto zeshishini. Inezinto ezininzi ezibalaseleyo zomzimba, ezenza zenze kakuhle kwizicelo ezahlukeneyo.
1. Imbonakalo kunye nokuluka
I-HPMC idla ngokuba ngumgubo omhlophe okanye ongekho mhlophe, ongenakuthelekiswa nanto, engenaxabiso kwaye engenabungozi. Ingachithwa kumanzi abandayo kunye nezinyibilikisi ezithile zezinto eziphilayo (ezinjengeenyikima ezixutywe njenge-ethanol / amanzi kunye ne-acetone / amanzi), i-ether ne-Ether kunye ne-chloroform. Ngenxa yobume bayo be-ionic, ayiyi kuphinda enze njani impendulo ye-electrolytic kwisisombululo esinamandla kwaye akasayi kuchaphazeleka kakhulu kwixabiso le-pH.
2. I-Vilosity kunye ne-RheOology
Isisombululo se-HPMC AXCEAUROILY sine-tickeng elungileyo kunye neThixitRopy. Iindidi ezahlukeneyo ze-Nurincel®hpmc zinee-viwossies ezahlukeneyo, kwaye uluhlu oluqhelekileyo luyi-5 ukuya kwi-100000 Mpas (2% le-MPAFOOOR (i-20 ° C). Iso sisombululo sibonisa iPseudoplastic, oko kukuthi, i-Shearting Gutnomenon, kwaye ilungele iimeko zesicelo ezifana nokunxiba, ukuntywila, imingxunya, njl njl. Efuna ukuba i-ratheology elungileyo.
I-3. Ukungcwaba i-thermal
Xa i-HPMC ishushu emanzini, ukucaca kwesisombululo kuyancipha kwaye ijeli yenziwa kwiqondo lobushushu elithile. Emva kokupholisa, i-gel State i-gell iya kubuyela kwisisombululo. Iindidi ezahlukeneyo ze-HPMC zineqondo lobushushu elahlukileyo, ngokubanzi phakathi kwe-50 ne-75 ° C. Le mpahla ibaluleke ngokukhethekileyo kwizicelo ezinje ngodaka lokwakha kunye ne-chiermacelical capsules.
4. Umsebenzi womphezulu
Ngoba iimolekyuli ze-HPMC ziqukethe amaqela e-hydrophobic kunye ne-hydrophobic, babonisa umsebenzi othile kwaye banokudlala imisebenzi ethile, basasaza kunye nokuzisasaza kunye nendima yokuzinzisayo. Umzekelo, kwi-caressings kunye ne-emulsions, i-HPMC inokuphucula uzinzo lwe-emulsion kwaye ikhusele i-sediment yamasuntswana e-pigments.
I-5. Hygroscopicicicity
I-HPMC ine-hygroscoficity ethile kwaye inokufunxa umswakama kwindawo enomswana. Ke ngoko, kwezinye iinkqubo, ingqalelo kufuneka ihlawulwe ukupakisha ukutywinwa ukuthintela ukuthandwa komswakama kunye ne-AgeGlomeration.
I-6. Ukusekwa kwepropathi yefilimu
I-HPMC inokwenza ifilimu enzima nengabonakaliyo, esetyenziswa ngokubanzi ekutyeni, amayeza (anjengeearhente zokuhlalisa) kunye neengubo. Umzekelo, kumzi-mveliso wamayeza, ifilimu ye-HPMC inokusetyenziswa njengecwecweli ekuphuculeni uzinzo kunye nokukhululwa kolawulo lolawulo.
I-7. I-BioMPiatise kunye nokhuseleko
I-HPMC ayinatyhefu kwaye ayinabungozi, kwaye inokukhuseleka ngokukhuselekileyo ngumzimba womntu, ngoko ke isetyenziswa ngokubanzi kumacandelo amayeza nokutya. Njengowona unomdla wemifanekiso, ihlala isetyenziselwa ukuvelisa iitafile ezikhuselekileyo zokukhutshwa, iigobolondo zecapsule, njl.
8. Uzinzo lwePh
I-HPMC iyazinza kwi-PH ye-3 ukuya kwi-11, kwaye ayinakwenzeka ngokulula okanye ichaphazeleke yi-acid kunye neAlkali, ukuze isetyenziswe kwiindidi zeekhemikhali, njengezixhobo zokwakha, iikhemizo zemihla ngemihla kunye neendlela zekhemikhali zemihla ngemihla.
9. Ukuchasana netyuwa
Isisombululo se-HPMC sizinza kwizitya ze-Inorganic kwaye ayisebenzi lula okanye ayisebenzi kakuhle ngenxa yotshintsho kwi-ion yoxinaniso, eyenza ukuba ihlale isebenza kakuhle kwezinye iinkqubo zetyuwa (ezinje ngodaka lwe-ceace).
10. Uzinzo lwe-thermal
I-Nuncel®HPMC inozinzo oluhle kwimimandla yobushushu obuphezulu, kodwa inokude ikhuphe okanye idrafti xa ityhilwe kubushushu obuphezulu ixesha elide. Ingagcina ukusebenza kakuhle ngaphakathi koluhlu oluthile lobushushu (ihlala ingezantsi kwe-200 ° C), ngoko kufanelekile ukulungiselela ukusetyenziswa kobushushu obungaphantsi kobushushu.
11. Uzinzo lwekhemikhali
I-HPMCIsinzile kukukhanya, ii-oxidants kunye neekhemikhali eziqhelekileyo, kwaye azichaphazelekanga ngokulula izinto zangaphandle zekhemikhali. Ke ngoko, inokusetyenziswa kwiimveliso ezifuna ukugcinwa kwexesha elide, ezinjengezinto zokwakha kunye namayeza.
I-Hydroxypropyl Methylcelcelgalose isetyenziswa ngokubanzi kumashishini amaninzi ngenxa yokungazimiseki ngokupheleleyo, ukuqina, ukungqubana kwefilimu, iiprofayili zefilimu kunye nokuzinza kwefilimu kunye nokuzinza kwefilimu kunye nokuzinza kwefilimu kunye nokuzinza kwefilimu kunye nokuzinza kwefilimu. Kumzi-mveliso wokwakha, inokusetyenziswa njengendawo yokuthamba i-cericker; kumzi-mveliso wamayeza, inokusetyenziswa njengokuthabatha amayeza; Kwishishini lokutya, luyinto eqhelekileyo yokutya. Yizi propaties ezikhethekileyo zomzimba ezenza i-HPMC yezinto ezibalulekileyo zePolymer.
