Yintoni i-hydroxypropyl methylcelceluplose eyenziwe ngayo?

I-HydroxyPOpyl Methylcelcelsele (i-HPMC) yi-polymer esetyenziswayo kunye ne-polymer esetyenziswe ngokuguquguqukayo kwimizi-mveliso eyaziwayo, eyaziwa ngokuba yipropathi yayo eyahlukileyo kunye nezicelo. Le phunga isuswe i-seluplose, i-polymer yendalo ifunyenwe kwiindonga zeseli zezityalo. Ukuqonda ubume be-hydroxypropylmethylcelcelcelcelcelose, kuyimfuneko ukuba ube nesakhiwo kunye nesynthesing yale seluplose.

Ulwakhiwo lweSellUX:

I-seluplose yi-carbohydrate equka i-chain yomgca we-β-dlucose edityaniswe yi-β-1,4-Glycosidic Bonds. Ezi nkuqu zeeglucose zibanjwa kunye yi-hydrogen I-SellUlose yeyona nto iphambili yolwakhiwo lweendonga zeseli zezityalo, ukubonelela ngamandla kunye nobungqola bokutyala iiseli.

I-Derivertives ye-hydroxypropyl methylcelceluplose:

I-Hydroxypropyl Methylcelcelsulose idityanisiwe yi-scocials eguqula i-scocial kunye nokwazisa i-hydroxypropy kunye namaqela e-methyl ukuya kwikhonkco eliphambili lesellulose. Imveliso ihlala ibandakanya la manyathelo alandelayo:

Ukuphendula kwe-ether

I-Methylity: Ukunyanga isellulose ngesisombululo se-alkaline kunye ne-methyl chloride ukwazisa amaqela e-methyl (-Ch3) kwiqela le-hydroxyl (-) lesellulose.

I-Hydroxyypropyply: I-Methy-Seledise Seleclose iphinda iphinde isebenze nge-propylene oxide ukuba ingenise amaqela e-hydroxypropyl (-C2chohch3) kwisakhiwo seselselose. Le nkqubo iphucula ukulingana kwamanzi kwaye kutshintsha iipropathi zomzimba weselutiese.

Ukucocwa:

I-selupulose eguqulweyo ke ihlanjululwe ukuze isuse nayiphi na iregents engachazwanga, ngeemveliso okanye ukungcola.

Ukomisa kunye nokugaya:

I-hydroxypropyl ye-hydropyl ye-hydylcelcelgalose yomiswe kwaye iphantsi komgubo ococekileyo elungele ukusetyenziswa kwizicelo ezahlukeneyo.

Izithako ze-hydroxypropyl methylcelcelcelose:

Ukuqulunqwa kwe-hydroxypropyl methylcelcelcelose ibonakaliswa ngumgangatho wokufakwa endaweni yokufaka endaweni ye-hydroxypropy kunye namaqela e-hydyl kuthathe indawo ye-hydroxyl. Amabakala ahlukeneyo e-HPMC anezinqanaba ezahlukeneyo zokufakwa endaweni, echaphazela isothuliso lwabo, uVeksisity kunye nezinye iipropathi.

Ifomula yekhemikhali ye-HydroxyPOpyl Methylcelcelose inokubonakaliswa njengoko (c6h7o2 (o) (OCH2CH (OC) _X, apho kubonisa inqanaba lokufaka endaweni.

m: Inqanaba le-methylid (amaqela e-methyl kwiyunithi ye-glucose)

N: Inqanaba le-hydroxypropypy (i-hydroxypropy yeyunithi nganye ye-glucose)

x: Inani leeyunithi ze-glucose kwi-selsulose chain

Amanqaku kunye nokuSetyenziswa:

Ukuluka: i-HPMC kukunyibilika kwamanzi, kwaye inqanaba lokufaka endaweni ichaphazela iimpawu zalo zokuluka. Yenza isisombululo esicacileyo nesivisisa emanzini, sisenza sibe lilungele iindlela ezahlukeneyo.

I-Viskosity: Uhlobo lwesisombululo se-HPMC luxhomekeke kwizinto ezinje ngobunzima bemolekyuli kunye nesidanga sokufaka endaweni. Le mpahla ibalulekile kwizicelo ezinje ngamayeza afuna ukukhululwa okhuphayo.

Ukuqulunqwa kwefilimu: I-HPMC inokwenza iifilimu ezincinci njengesisombululo, zenza ukuba kube luncedo kwi-carmasces, ukutya kunye namanye amashishini.

I-Stabilibers kunye ne-TICKITER: Kwishishini lokutya, i-HPMC isetyenziswa njengendawo enkulu kunye nokuzinza kwiimveliso ezahlukeneyo, kubandakanya iisosi, iintsana, kunye nezinto ezibhakiweyo.

Izicelo zamayeza: I-HPMC isetyenziswe ngokubanzi kwifomu yamayeza, kubandakanya iitafile, iicapbules, kunye nezisombululo ze-Ophthalmimis, ngenxa yepropathi yakhe elawulwa kunye ne-biomatise.

Ukwakhiwa kunye neengubo Ikwasetyenziswa njenge-thi cokener kunye ne-stabilizer ekupeyinta kunye nokunyanzeliswa.

Iimveliso zononophelo lobuqu: kwishishini lokhathalelo kunye ne-HPMC, i-HPMC ifumaneka kwiimveliso ezinjengeekhrim, i-lotions kunye ne-shampoos, apho ibonelela ngozinzo nozinzo.

I-HydroxylPOpyl MethylcelcelXose ifunyenwe yi-methytrapy kunye ne-hydroxyyprocy yesellulose. Yinto enesiporho esinenjongo ezininzi ngoluhlu olubanzi lokusebenzisa. Iipropathi zayo ezizodwa zenza ukuba zibe yinto exabisekileyo kumashishini anje ngamayeza, ukutya, ukwakhiwa kunye nokhathalelo lobuqu. Utshintsho olulawulwayo lwesellulose lunokulunga kwipropathi ye-HPMC, esenza ukuba ibe yinto ebalulekileyo kwiimveliso ezininzi esidibana nazo kubomi bethu bemihla ngemihla.
