Umahluko phakathi kwe-methylcelculose ne hydroxlyropyl methylcelcelceluplose

Methylcelsulose (MC)kwayehydroxypropylmethylcelose (hpmc)Zombini ezi ntlobo ziqhelekileyo zeselselose, ezisetyenziswa ngokubanzi kukutya, amayeza, amayeza, e-cosmetics, ulwakhiwo kunye neshishini. Nangona izakhiwo zazo ezisisiseko zekhemikhali zivela kwisellumse, kukho umahluko obalulekileyo kwiipropathi zemichiza, iipropathi zomzimba kunye neendawo zesicelo.

1. Umahluko wamachiza

I-methylcelculose (MC) yenziwa ngokutshintsha inxenye yeqela le-hydroxyl (---) kwimolekyuli yeselselose nge-methyl (-och3) amaqela. Inqanaba le-methyling linokulawulwa, lidla ngokuchazwa njengenqanaba lokufakwa kwengqondo. Ubume be-MC bulula, ubukhulu becala amaqela e-hydroxyl kwi-selselose theinsul itshintshwe ngamaqela amazi.

Hydroxypropyl methylcellulose (HPMC) is based on methylation, and further replaces part of the hydroxyl (-OH) groups on the cellulose molecule with hydroxypropyl (-C3H7OH) groups. Ke ngoko, i-HPMC isungulwa kwe-methylceltulose, kodwa inobuqhetseba ngakumbi. I-HPMC iqulethe amaqela amabini, i-methyl kunye ne-hydroxypropy, ke imeko yayo inzima kakhulu kuneMC.

2. Iipropathi zomzimba kunye nokuluka

Umoya wobuchule:

UMethylceluplose unokwenza isisombululo seColoidal kumanzi abandayo, kodwa akukho lula ukunyibilika emanzini ashushu. Ukuluka kwayo kuchaphazeleke kakhulu bubushushu bamanzi kunye nexabiso lamanzi, ngakumbi xa iqondo lobushushu liphuma, i-slibulaty ye-MC iya kuncipha.

I-HydroxyPOpyl Methylcelcelcelose inolwazi olungcono. Inokwenza isicombululo esizinzileyo kumanzi abandayo, kwaye isothulolo sayo sikwabonisa uzinzo oluhle phantsi kotshintsho lwamanzi pH kunye nobushushu. I-HPMC inomhlaba ophakamileyo wamanzi kwaye unokunyibilika kuluhlu lobushushu olubanzi, ngakumbi kumanzi ashushu.

I-Viskosity:

Isisombululo se-methylcelsulose sinophawu olusezantsi, ngoko ke lisetyenziswa kwezinye izicelo ezifuna uVeksisity osezantsi.

I-Hydroxypropyl Methylcelcelse Isisombululo ngokubanzi, nto leyo eyenza i-HPMC idla ngokusetyenziswa kwezinye izicelo ezifuna ukubonwa ngaphezulu, ezinje ngamalungiselelo okukhululeka amachiza.

Iipropathi zentshutshiso:

I-methylcellulose inento ebalulekileyo yokungalawulekiyo, oko kukuthi, iyakwenza into ethile emva kokufudumeza, kwaye iphinde inyibilike xa iqondo lobushushu lihla. Ke ngoko, ihlala isetyenziswa njengearhente yegeli ekutyeni nasekuhlaleni.

I-HydroxyPOpyl Methylcelcelgalose idla ngokungathi i-genomenon ye-thermal, kwaye idla ngokwenza isisombululo esizinzileyo emanzini kunokuba senze ijeli.

3. Iindawo zesicelo
Ishishini lokutya:
I-methylcelculose isetyenziswa ikakhulu ekutyeni yokuphucula incasa, yonyusa i-viscofity kwaye igcine ubume bokutya. Umzekelo, inokusetyenziswa ngokutya okuphezulu, i-ice cream kunye neemveliso zenyama yenyama. Ngenxa yeepropathi zayo zokuthengisa i-thermal, inokusetyenziswa njenge-arhente yegqwetha ekutyeni.
I-Hydroxypropyl Methylcelcelsulose ayifane isetyenziswe ekutyeni, kodwa inokusetyenziswa kukutya okuthile okusebenzayo, njengabarhafi kunye ne-eulsiber.

Ishishini lamachiza:
UMethylcellulose uhlala usetyenziswa njengokuthanda amachiza, ngakumbi kwiitafile, iicapbules kunye neengubo zamayeza. Ingasetyenziswa njenge-arhente yokukhutshelwa okuzinzileyo ye-Opthalmic amachiza ancedise ekuqaliseni ixesha lesenzo seziyobisi.
I-HydroxyPOpyl Methylcelcelsulose isetyenziswa ngokubanzi kumalungiselelo echiza, ngakumbi kwiitafile, iicaphule kunye namacebo olwenzi. Idlala indima ebalulekileyo ekugcineni kokukhululwa kwamachiza kunye neenkqubo ezilawulwa-zilawulwa. Ukongeza, i-HPMC ikwasetyenziswa rhoqo kwi-Opthathalmic amachiza kunye neearhente zokulungisa i-MUCOSA.

Ishishini lokwakha:
I-methylcelculose isetyenziswa ikakhulu njengearhente ye-tickener kwaye igcina amanzi e-rickener yezinto zokwakha ezifana nesamente kunye ne-gypsum kwishishini lokwakha. Ingaphucula iipropathi eziqhutywa kwaye isebenza kwezi zixhobo.
I-Hydroxypropyl Methylcelcelsulose isetyenziswa ngokubanzi kwizinto zokwakha, ngakumbi ekwakheni iimveliso ezinjengeetrani kunye nokugcinwa okuphezulu kunye nokugcinwa kwamanzi.

Ishishini leCosmetic:

MCihlala isetyenziswa njenge-thi checker, i-hindent kunye ne-mulsifier kwi-cosmetics ukuphucula intuthuzelo yesikhumba kunye neziphumo zokunyathela.

I-HPMCihlala isetyenziswa kwiimveliso zolusu kunye neemveliso zeenwele, ngakumbi kwiimveliso ezinjengee-gells, iikhrim kunye ne-shampoos, ezinokubonelela ngolungelelwano kunye nefuthe elingcono.

Nangona i-methylcelculose (mc) kunye ne-hydroxypropyl methylcelcelcelse (i-HPMC) zizo zombini iiselfowuni zombini, izakhiwo zabo zekhemikhali kunye nezinto ezibonakalayo zahlukile, zikhokelela kwizicelo ezahlukeneyo. I-MC ihlala inophawu olusezantsi kunye neepropathi zentshutshiso, kwaye ilungele ukusetyenziswa njengearhente yegengi kunye ne-tickerer; Ngelixa i-HPMC inobuchule obungcono kwaye ihlala isetyenziswa kwizicelo ezifuna i-viscofity ephezulu kunye nokuzinza okuphezulu, ngakumbi kumashishini okwakha kunye nokwakha. Ngokweemfuno ezahlukeneyo zokusebenzisa, ukukhetha izinto ezifanelekileyo zesellulose kunokuhlangabezana kakuhle neemfuno zezicelo ezithile.
