Hydroxypropyl methyl seluplose vs methyl seluplose

I-seluplose yeyona nto iphambili kwiindonga zeseli zezityalo kunye nesona sisebenzela i-polymer eninzi emhlabeni. Izibonelelo zeSeletulose zisetyenziswa kuluhlu olubanzi lwezicelo zomsebenzi, kubandakanya nokutya, amayeza kunye nolwakhiwo. Ezona zimbini zithandwayo zeselsuloses zi-hydroxypropyl methylcelcelcelculose (hpmc) kunye ne-methylcelculose (MC). Ezi mveliso zimbini zihlala zisetyenziswa ngokuthe ngcembe, kodwa banomahluko obonakalayo ekufuneka uqwalaselwe.

Yintoni i-hydroxypropyl methylcelcelose?

I-Hydroxypropyl Methylcelcelcelose i-Insulose ye-Ethen, inyibilikiswe amanzi e-ether evela kwi-polymer yendalo. Isakhiwo se-MPMC se-HPMC siyafana ne-sellyulose yendalo, esenza ukuba ibe yindlela enokwenzeka kwizicelo ezininzi zoMzi-mveliso. Iipropathi zayo ezahlukileyo zemolekyuli, kubandakanya ukubenzela ukungcungcutheka kunye nokujonga izinto, kuyenza ilungele ukusetyenziswa kwezinto zokwakha, ukutya, amayeza kunye ne-cosmetics.

Iimpawu ze-HPMC:

Enye yezona zibonelelo zibalulekileyo ze-HPMC kukomelela. I-HPMC inyibilikiswe ngokulula emanzini abandayo, yenze isisombululo esicacileyo, esizinzileyo esizinzileyo, esizinzileyo, i-viscous. Oku kwenza ukuba i-HPMC inamathela ofanelekileyo kumashishini aliqela, kubandakanya nolwakhiwo kunye namayeza.

I-2. UVIKILE:
I-HPMC ine-viscofity ephezulu kwaye ilungele ubutshinga. I-viscosity yayo ephezulu ikakhulu icacisiwe kwi-hydroxylpropy ye-hydroxyl kunye namaqela e-Masxsy, eyandisa amandla ayo okwenza iibhondi ze-hydrogen kwaye kukhuthaza ukusebenzisana kweemolekyuli zamanzi.

3. Ukuqulunqwa kwefilimu:
I-HPMC yiarhente yefilimu ebalaseleyo yefilimu kwaye iqhele ukusetyenziswa kumzi-mveliso wamachiza wepilermaceutical amachiza kunye neecapsules. Oku kudala umqobo ngokuchasene nokufuma kunye nezinye izinto zokusingqongileyo, okunokwenzeka okunokwenzeka ukuba kunciphise ubomi beshels yechiza.

4. Ucoceko oluphezulu:
I-HPMC icocekile kwaye yimveliso yendalo enganayo nayiphi na imichiza eyingozi. Oku kwenza ukuba ilungele ukutya kunye nemizi-mveliso yenkcitho.

Yintoni iMethylceLceLcelup

I-methylcellulose ikwasisisele i-Ether ethathwe kwiintsinga zeselfowuni. Ngumgama we-methyl esutise ye-sellyulose, kunye nesakhiwo sayo semolekyuli sahluke kakhulu kwi-seluplose yendalo, eyenza ingaphantsi kwe-enzyme ukonakaliswa. I-methylcelculose yicandelo elisetyenziswa ngamalungu amaninzi asetyenziswa kwimizi-mveliso eyahlukeneyo kubandakanya ukutya, amayeza, ulwakhiwo kunye ne-cosmetics.

Iimpawu zikaMethylceluplose:

1. Ukuzalwa kwamanzi:
UMethylcelupaluplose uyanyibilika ngokulula emanzini abandayo, enze i-viscous ecacileyo, i-viscous, nesizinzileyo esizinzileyo. Kodwa i-solity yayo isezantsi kune-HPMC. Oku kwenza ukuba kube lula ukusetyenziswa kumashishini afuna inqanaba eliphezulu lomoya, njengokwakha.

I-2. UVIKILE:
UMethylceluplose une-viscofity ephezulu kwaye ulungele ulwelo oluqatha. I-viscofity yayo ichazwe kwi-methyl imisebenzi yayo esebenzisana neemolekyuli zamanzi.

3. Ukuqulunqwa kwefilimu:
UMethylceluplose yiarhente yefilimu ebalaseleyo yefilimu kwaye iqhele ukusetyenziswa kumzi-mveliso wamayeza ukulungiselela ukunqula amachiza amachiza amayeza kunye necapsules. Nangona kunjalo, ukusebenza kwalo kwefilimu kuphantsi kancinci kwi-HPMC.

4. Ucoceko oluphezulu:
UMethylceluplose ucocekile kakhulu kwaye yimveliso yendalo enganayo nayiphi na imichiza eyingozi. Oku kwenza ukuba ilungele ukutya kunye nemizi-mveliso yenkcitho.

Thelekisa phakathi kwe-HPMC kunye ne-MC:

I-1. Ukungasebenzi:
I-HPMC inyibilike kakhulu emanzini kune-methylceltulose. Olu mahluko we-solbaubisity wenza i-HPMC yendlela enokwenzeka kumashishini afuna ukuluka kakhulu, njengokwakha.

I-2. UVIKILE:
Zombini i-HPMC kunye neMethylceltulose zinokufakwa okuphezulu. Nangona kunjalo, i-vickosity ye-HPMC iphakamile kancinane kune-methylcelculose. Oku kwenza ukuba i-HPMC ilungele ukusetyenziswa kumashishini afuna ukundwendwela okuphezulu, njengokutya kunye ne-cosmetics.

3. Ukuqulunqwa kwefilimu:
I-HPMC kunye ne-methylcelceltulose zii-arhente zokwenza ifilimu. Nangona kunjalo, i-HPMC ineepropathi ezingcono zefilimu kune-methylceltulose, eyenza ilungele ukusetyenziswa kumzi-mveliso wamachiza.

I-4. Ukucoceka:
I-HPMC kunye ne-methylcelcelculose zombini zicocekile iimveliso zemvelo ezingenazo naziphi na iikhemikhali eziyingozi.

I-Hydroxypropyl Methylceltulose kunye neMethylcelcelgalose zizinto ezibalulekileyo zeselfowuni ezisetyenzisiweyo kumashishini ahlukeneyo. Zombini iinqobo zokudibanisa zinokuqina okuphezulu, i-viscofity ephezulu, iipropathi ezigqwesileyo zefilimu kunye nokucoceka okuphezulu. Nangona kunjalo, ukuluka kunye nokujonga kwe-HPMC kunqabile kunezo ze-methylcelupalupalsulose, zenza kube lula kwimizi mveliso efuna ukonakala okuphezulu kunye nokubonisa. Ukongeza, i-HPMC ineepropathi ezingcono zefilimu kune-methylceltulose, eyenza ilungele ukusetyenziswa kumzi-mveliso wamachiza. Nangona kunjalo, zozibini iikhomputha zinepropathi eyahlukileyo ebangela ukuba zilungele ukusetyenziswa kumashishini ahlukeneyo, kwaye ukusetyenziswa kwazo kufuneka kuthathelwe ingqalelo ngokusekwe kwisicelo esithile.
