Nguwuphi umahluko phakathi kwe-HPMC ne-CMC?

I-HPMC (Hydroxypropyl Methylcelcelcelse) kunye ne-CMC (i-CMC (i-carboxymethyl iselsulose) zisetyenziswa ngokutsha kwezinto eziqhelekileyo, ezisetyenziswa kakhulu kukutya, ezisetyenziswa kakhulu kukutya, ukwakhiwa kwamanye amasimi.

I-1. Ubume kunye nendlela yokulungiselela

I-HPMC:
Isakhiwo sekhemikhali: I-HPMC yindawo ye-polymer ye-polymer efunyenwe ngokusabela ngokuphendula ngendalo kunye ne-proplone oxide kunye ne-methyl chloride emva konyango lwe-Alkali.

Iyunithi ephambili yesakhiwo yiringi ye-glucose, exhunyiwe yi-1,4-β-glucosidic, kwaye amaqela e-hlucosidic, kwaye amaqela e-hlucosidi atshintshwa yi-Accordy (-Chacchohch₃).
Indlela yokulungiselela: Okokuqala, i-seluplose inyangwa ngesisombululo seSodium hydroxide ukwenza i-Alkali SellUlose, emva koko iphendulwe kwi-proloride ye-proloride kwaye ihlanjululwe kwaye ihlanjwe yafumana i-HPMC.

I-CMC:
Isakhiwo sekhemikhali: I-CMC yi-anaion selsulose efunyenwe ngokuphendula ngokuphendula nge-cleulose nge-chlorocetic acid phantsi kweemeko ze-Alkaline.
Iyunithi ephambili yesakhiwo ikwangumsesane weglucose, edibene ne-1,4-β-glucosidic, kwaye amaqela e-hlucosidic, kwaye amaqela e-hlucosidi atshintshwa yi-carboxymethyl (-ch₂cooh).
Indlela yokulungiselela: I-seluplose iphinda isebenze nge-sodium hydroxide ukuba i-alkali i-alkali, emva koko iphinde iphinde isebenze nge-chlorocetic acid, kwaye ekugqibeleni ihlatywe, ihlazo kunye ne-dribes kunye ne-dribes kunye ne-dminas kunye ne-drish kunye ne-dribes kunye ne-dminas kunye ne-drish kunye ne-dmicks kunye ne-dmina yokuhamba kunye ne-drish kunye ne-drish kunye ne-dribes kunye ne-drish kunye ne-dribes ifumana i-CMC.

2. Iipropathi zomzimba kunye neekhemikhali.

Umoya wobuchule:
I-HPMC: inyibilikiswa emanzini abandayo kunye nezinye izinyibilikisi zezinto eziphilayo, ezingenamanzi ashushu. Xa isisombululo sipholile, ijeli ebonakalayo isenziwa.
I-CMC: inyibilikisa emanzini abandayo kunye namanzi ashushu ukwenza isisombululo se-colloidal ye-viscoidal.

I-Viskosity kunye ne-RUOOLOLOGL:
I-HPMC: inesiphumo esihle sokuziqhelanisa nokuzinquma kwesisombululo esinamandla, kwaye i-pseudoplastic (i-Shearling) i-RIOLOTRTERTRTERTERE.
I-CMC: inophawu oluphezulu kunye neepropathi ezintle zeRheeology kwisisombululo esinamandla, sibonisa iThokotdropy (i-Thsuceling xa sitsiba, sinciphile xa sikhutshiwe) kunye nePseudoplastity.

3. Amasimi esetyenziswayo

I-HPMC:
Umzi-mveliso wokutya: Njengomzi omkhulu, i-stickener, i-eulsifier kunye nefilimu yangaphambili, isetyenziswa kwi-ice cream, iimveliso zobisi, ijelly, njl.
Umzi-mveliso wamachiza: Isetyenziswe njenge-binder, i-Intericran kunye ne-Arhente yokukhutshwa kwethayile yokulungiselela itafile.
Izinto zokwakha: Isetyenziswe kwi-creating cender kunye neemveliso ze-gypsim ukuphucula ukugcinwa kwamanzi kunye nokusebenza.
I-cosmetics kunye neemveliso zononophelo zobuqu: Isetyenziswe kwi-ivores, iikhrim, i-shampoos kunye neegels zeshawari, njl njl.

I-CMC:
Umzi-mveliso wokutya: Njengoko i-thickener, i-stickener kunye ne-emulsifier, isetyenziswe eJam, eJely, i-ice cream kunye neziselo.
Ishishini lamachiza: Isetyenziswe njenge-binder, ihlazo kwiitafile zamachiza kunye nefilimu yangaphambili yeecaphus zamachiza.
Imveliso yepakethi: isetyenziswe njenge-arhente yamandla kunye nearhente yobuqhetseba yokuphucula amandla owomileyo kunye noshicilelo lwephepha.
Umzi-mveliso we-imeyile: isetyenziswe njengearhente yokubonisa kunye nearhente yokugqiba ukuphucula amandla kunye ne-gloss yendwangu.
Umzi mveliso weekhemikhali zemihla ngemihla: Isetyenziswe njenge-tickener kunye nokuzinza kwezinto zokucoca, iimveliso zezinyo kunye nonyango.

4. Ukukhusela kwendalo kunye nokhuseleko

Zombini i-HPMC kunye ne-CMC ayinabungozi kwaye ingakhathali ze-polymer ezingenakuqhutywa zii-enzymes zokugaya emzimbeni womntu kwaye zithathwa njengezongezo zokutya okukhuselekileyo kunye nezixhobo zokutya ezikhuselekileyo. Zitshabalalisiwe ngokulula kwindalo esingqongileyo kwaye zinokungcoliseka okuncinci kwindalo.

I-5. Iindleko kunye nokunikezelwa kwentengiso

I-HPMC isetyenziswa ikakhulu kwimimandla enemisebenzi yentsebenzo ephezulu ngenxa yenkqubo yayo yokulungiselela entsokothi, iindleko eziphezulu zemveliso kunye nexabiso eliphezulu.

Inkqubo yemveliso ye-CMC ilula, iindleko ziphantsi, ixabiso linoqoqosho, kwaye uluhlu lwesicelo lubanzi.

Nangona i-HPMC kunye ne-CMC zizo zombini iitywina zeselfowuni, zibonisa iimpawu ezahlukeneyo kunye nokusetyenziswa ngenxa yezixhobo ezahlukeneyo zekhemikhali, iipropathi ze-physicochemical kunye neendawo zesicelo. Ukukhetha kwayo i-seluplose yokusebenza ukuze isetyenziselwe ukusetyenziswa kuhlala kuxhomekeke kwiimfuno ezithile zesicelo kunye nokuqwalaselwa kwezoqoqosho.
