Iimpawu ze-hydroxypropyl methylcelculose (hpmc)

I-HydroxyPOpyl Methylcelcelculose (i-HPMC) yindawo ebaluleke kakhulu ye-polymer ye-polymer kunye ne-selsulose. Isetyenziswe ngokubanzi kumayeza, ukwakhiwa, ukutya, i-cosmetics kunye namanye amasimi. I-HPMC inezinto ezithile ezizodwa zomzimba kunye neekhemikhali ngokuguqulwa kweekhemikhali zemolekyuli yemolekyuli, edibana neemfuno ezahlukeneyo zezamashishini.

1. Ubume bemolekyuli kunye neepropathi
Isakhiwo se-geculari se-HPMC sine-skeleton esekwe kwi-selsulose kunye nezinto ezahlukeneyo (i-hydroxypropy ye-methyl). Ngokuguqulwa kwamachiza, amaqela e-Hydroxyl kunye namaqela e-methyl azaziswa kwiimolekyuli ze-HPMC, enika isolula amanzi, ukuthambisa, ukwenza ezinye iipropathi. Ngenxa yesakhiwo sekhemikhali se-HPMC, ayinyibilikisi emanzini nase-organic, kodwa inokwenza isisombululo esibonakalayo emanzini.

Iqela layo le-hydroxypropy yonyusa i-hydrophiility, ngelixa iqela le-METYL liphucula i-hydrophoindity. Ngokuhlengahlengiswa komyinge wale milinganiselo mibini, ukuluka kwamanzi, ukugcinwa kwamanzi kunye nezinye iipropathi zomzimba kunye neekhemikhali ze-HPMC kungatshintshwa ukuhlangabezana neemfuno zesicelo zemimandla eyahlukeneyo.

I-2. Ukungasebenzi kunye nokuntywila
I-HPMC inomoya olungileyo, ngakumbi xa inyibilikisiwe emanzini afudumeleyo, iya kuphinda ibeke isisombululo esifanayo. Inamandla okuqina okuqinileyo kwaye inokufunxa amanzi ukuze idumbe kwaye yenze isisombululo seColloidal esizinzileyo. Oku kwenza ukuba i-HPMC isetyenziswe ngokubanzi kwii-thi chuishers, izilo, i-eulsiberiers kunye neminye imisebenzi, ngakumbi kukukhululwa kwamachiza, ukulungiselela ukuqhuba kunye nomzi mveliso wokutya.

Kumzi-mveliso wamachiza, i-HPMC ihlala isetyenziselwa ukulungiselela amalungiselelo okuhambisa iziyobisi, anokulawula ngokufanelekileyo inqanaba lokukhupha amachiza. Ukubizwa kwayo kunye nokungasebenzi kwayo kwenza ukuba kube lula ukunyibilika kwiphecana le-gestrointenal, kwaye likhuphe kancinci iziyobisi, kwaye landisa ukusebenza ngempumelelo kweziyobisi.

I-3. Ukutyibilika kunye ne-Gel
Inqaku elibonakalayo le-HPMC liqaqanjelwa. Uhlobo lwesisombululo se-HPMC unxulumene ngokusondeleyo noxinzelelo lwayo, ubunzima bemolekyuli kunye nenqanaba le-hydration. Isisombululo esiphakamileyo se-HPMC SPMMC sinophawu olukhulu lwe-HPMC kwaye ilungele izicelo ezifuna ukubonwa okuphezulu, njengababulala, iingubo, iintambo, njl.

I-HPMC ikwanazo neepropathi zokulungisa. Xa uxinzelelo lwesisombululo se-HPMC luphezulu, linokwenza ijeli ebonakalayo, ebaluleke kakhulu kwicandelo lamayeza, ngakumbi kumalungiselelo okukhutshwa kweziyobisi kunye nejeli efana nejeli.

4. Uzinzo kunye neepropathi ze-antioxidant
I-HPMC inozinzo oluhle lweekhemikhali kwaye inokunyamezela uluhlu olubanzi lweenqobo ze-PH (ngokubanzi 4 ukuya ku-10). Ke ngoko, inokugcina ubume bayo kwaye isebenze kwiindawo ezininzi ze-acid kunye ne-alkaline. Xa kuthelekiswa nezinye izinto zeselselese, i-HPMC ineepropathi ze-antioxidant kwaye inokusetyenziswa ngeendlela ezahlukeneyo zokugcina ixesha elide.

Ukuzinza kwemichiza kwenza ukuba i-HPMC isetyenziswe ngokubanzi kwizongezo zokutya, i-cosmetics kunye namalungiselelo amachiza amayeza. Umzekelo, kumzi-mveliso wokutya, i-HPMC isetyenziswa njenge-emulsifier kunye ne-tickener ukuphucula ukuthungwa kunye nokuzinza kwemveliso.

I-5. I-Biomitise kunye nokhuseleko
I-HPMC, njenge-polymer enyibilikayo yamanzi, ineendlela ezintle kwaye isetyenziswa ngokubanzi kwigumbi lamayeza, ukutya kunye nemizi-mveliso yenkcitho. I-HPMC ayithathelwa ngokupheleleyo emzimbeni, kodwa njengefibrey yefayibha yenyibilikisiwe, ikhutshiwe ngenkqubo yokugaya kwaye ithathelwa ingqalelo ngokubanzi njengento engeyiyo ityhefu kunye nokungakhathali. Ihlala isetyenziswa njengesixhobo kwiinkqubo zokuzinikela iziyobisi ukunceda ukuthumela iziyobisi ngendlela ecothayo kunye nokuzinza.

Njenge-sogative yokutya, i-HPMC iqinisekisiwe yiKhomishini yeCodex Alielius njengento ekhuselekileyo yokusetyenziswa. Isicelo sayo sithatyathwa sikhuselekile kwaye singenabungozi emzimbeni womntu.

6. Amasimi esetyenziswayo
I-6.1 Ishishini lamayeza
Kumalungiselelo asechiza, i-HPMC isetyenziswa ngokubanzi njenge-thicker, i-eulsifier, i-stiblimizer kunye nomphathi okhululweyo. Kwiifom zedosi yomlomo, i-HPMC ihlala isetyenziswa kwiicapsules, iitafile kunye namalungiselelo okukhutshwa. Ngenxa yobulungisa bayo obulungileyo kunye nepropathi ehlengahlengiswayo, i-HPMC isetyenziselwa ukulungiselela abathwali ngamachiza, ngakumbi ekuphuhlisweni kweziyobisi ezinzileyo.

6.2 Ishishini lokutya
Kwishishini lokutya, i-HPMC isetyenziselwa ukuqina, ukuzinza, ukwahlulwa, ukwakhiwa kwefilimu kunye nezinye iinkalo. Ihlala isetyenziswa kwimpahla ebhakiweyo, i-gobgeges, ukutya okuthambileyo, ukutya kunye neesosi. I-HPMC inokuphucula ngokufanelekileyo incasa kunye nokuthungwa kokutya kwaye kwandise ubomi beshelufu yokutya.

6.3 I-cosmetics kunye nokhathalelo lomntu
Kwintsimi ye-cosmetics, i-HPMC ihlala isetyenziswa njenge-thickener kunye ne-mulsifier kwiimveliso zonyango, i-shampoo, ijeli yeshawari, izinyo, iicostheste, ezinye iimveliso. Inolusu oluhle kakhulu, inokuphucula ukungqinelana kunye nokuzinza kwemveliso, kwaye akukho lula ukucaphukisa ulusu ngexesha lokusetyenziswa.

6.4 Izicelo zoKwakha kunye neziSeko zeMizi-mveliso
Kumzi-mveliso wokwakha, i-HPMC isetyenziswa njenge-thi cokener ekwakheni izinto ezinjengokuthengiswa kwesamente, ukunamathela kwe-tile, kunye nengubo yodonga. Ingaphucula ukungasebenzi kakuhle kunye nolwelo ngexesha lokwakha, ukwandisa umlinganiso wezixhobo, kwaye iphucule amandla kunye nokuqina emva komile.

Njengezinto ezibalulekileyo zepolymer, i-HPMC ineentlobo ngeentlobo zeepropathi ezizezempilo zomzimba kunye neekhemikhali, ezinjengokungathobeli kwamanzi kakuhle, ukuthambisa, uzinzo kunye ne-bimatise. Uluhlu lwayo lwezicelo lubandakanya amayeza, ukutya, i-cosmetics, ulwakhiwo kunye namanye amashishini, ukubonelela ngemisebenzi yentsebenzo kunye nokusebenza kwentsebenzo kwiimveliso ezikweli candelo. Kwixa elizayo, njengemfuno yabantu yendalo esingqongileyo, esempilweni neyokuphumelela iyaqhubeka ukwanda, amathuba okusebenza e-HPMC asakhusela.
