Nguwuphi umahluko phakathi kwe-methyl seluplose kunye neseluplose?

I-methyl seluplose kunye nesellulose zombini ii-Polysaccharides, okuthetha ziimolekyuli ezinkulu ezenziwe ngee-molekyuli ezilula zeswekile. Ngaphandle kwamagama afanayo kunye neempawu zesakhiwo, ezi zinto zinemimandla enamacandelo afanelekileyo ngokwendlela abo yokwakha iikhemikhali, iipropathi kunye nokusetyenziswa.

I-1. Ubume bemichiza:

Iseli:
I-seluplose yi-polymer yemvelo eyenzeka ngokwendalo edityaniswe ziiyunithi zeglucose ezidityaniswe kunye β-1,4 Glycosidic Bonds. Ezi yunithi ze-glucose zilungiselelwe imixokelelwane emide emide, yenza izakhiwo ezomeleleyo, ezingqongqo. I-SellUlose yeyona nto iphambili kwiindonga zeseli zezityalo kunye ne-algae, zibonelela ngenkxaso yolwakhiwo kunye nobungqola.

I-Methyl Selelise:
I-Methyl Selelose kukukhupha i-sellyulose efunyenwe ngokunyanga isellulose ngesisombululo se-alkaline esomeleleyo kunye ne-methyl chloride. Olu nyango luphumela ekufakweni kwamaqela e-hydroxyl (--o) kwimolekyuli eselfowuni nge-methyl (-C3). Inqanaba lokufakwa endaweni (DS) libhekisa kwinani eliphakathi lamaqela e-hydroxyl Ngokubanzi, i-DS ephezulu ikhokelela ekunyuseni ukubekwa komhlaba kunye nokuncipha kweqondo lokuhlaselwa.

2. Iipropathi:

Iseli:
I-insolloble emanzini kwaye uninzi lwezinyibilikiswa zezinto eziphilayo ngenxa ye-hydrogen yayo enamandla.
Ukuqina okuphezulu kunye nokuqina kwencam, inegalelo kwindima yalo ekuboneleleni ngenkxaso yezityalo.
I-biodegramay kwaye ihlaziyekile, isenza ukuba ibe nobuhlobo.
Isakhono esilinganiselweyo esijikelezayo emanzini.
Ngokubanzi, isellulose ayilungelanga ukusetyenziswa ngokuthe ngqo ngabantu ngenxa yendalo yayo engacacanga.

I-Methyl Selelise:
Inyibilikiswe emanzini ukuya kwiidigri ezahlukeneyo kuxhomekeke kwinqanaba lokufaka endaweni.
Iifom ezibonakalayo kunye ne-viscous izisombululo xa zichithwe emanzini, zisenza zibe luncedo kwizicelo ezahlukeneyo ezifana nezicelo ezinamachaphaza, iingubo, kunye neearhente zokubaleka kwiimveliso zokutya.
Ukwazi ukwenza iiglasi kumaqondo obushushu aphakamileyo, abuyela kwisisombululo ekuphoxekeni. Le propati ifumana izicelo kwiindawo zamachiza, apho isetyenziswa khona njenge-genert matrix yokukhutshwa kweziyobisi.
Ingonakalisi kwaye ngokubanzi ithathelwe ingqalelo ekusetyenzisweni, ihlala isetyenziswa njengendawo yokutya, i-enulsifier, okanye iarhente yokuthambisa.

3. Izicelo:

Iseli:
Icandelo eliphambili lephepha kunye nekhadibhodi ngenxa yamandla ayo kunye nokuqina.
Isetyenziswe kwiindwangu kunye neendwangu, ezinje ngekotoni kunye nelineni, kwipropathi yayo yendalo yendalo.
Umthombo wemisebenzi yokuveliswa kwemveliso yeselselose enjenge-Methyl Selelose, i-carboxeyymethyl seluplose (CMC), kunye neSeluplose Acetate.
Ifunyenwe kwi-fiber ye-fiber ye-fiber, ukubonelela ngesikhumba kwisitulo kwaye sincedise ekugayeni.

I-Methyl Selelise:
Isetyenziswe ngokubanzi kumzi-mveliso wokutya njengearhente yokuthambisa, i-stabilizer, kunye ne-emulsifier kwiimveliso ezinjengesosi, isuphu, kunye needessert.
Izicelo zamayeza zibandakanya ukusetyenziswa kwayo njengeziqwenga zecwecwe, i-thi churener kwiikhrim kunye ne-oyile, kunye nearhente yegesi kulwelo lomlomo.
Isetyenziswe kwizixhobo zokwakha ezifana nodaka kunye nodaka ukuphucula ukusebenza kunye nokunamatheza.
Uqashwe kwiimveliso zononophelo zobuqu njengeziqhwithi kunye ne-sundos zokuziqhelanisa nokuzinzisa.

4. Impembelelo yeNdalo:

Iseli:
I-seluplose ivuseleleka kwaye ixabisekile, isenza ukuba ibe nobuhlobo.
Sisixhobo esizinzileyo njengoko sinokufumana kwizinto ezahlukeneyo ezisekwe kwizityalo, kubandakanya iipulp, umqhaphu, kunye neentsalela zezolimo.
Izixhobo ezisekwe seselfowuni zinokuphinda zisetyenziselwe ukuphinda zisetyenziselwe okanye ziqwalaselwe, ukunciphisa inkunkuma kunye nongcoliseko lwendalo.

I-Methyl Selelise:
I-Methyl Selelose isuselwa kwi-sellyulose, esenza ukuba ibe yindawo enobuhlobo kunye nokusingqongileyo.
Nangona kunjalo, inkqubo yokuhlengahlengiswa kwekhemikhali iyafuneka ukuba ivelise i-methyl sellulose ibandakanya ukusetyenziswa kweekhemikhali ezinjengeAlkalis kunye ne-methyl chloride, enokuba neempembelelo zokusingqongileyo ukuba azilawulwa ngokufanelekileyo.
Iindlela zokulahla inkunkuma ezifanelekileyo kunye neenkqubo zonyango lwenkunkuma ziyimfuneko ukunciphisa nayiphi na impembelelo yokusingqongileyo enxulumene nemveliso kunye nokusetyenziswa kwe-methyl sellulose.

5. ISIQINISEKISO:
I-Methyl Selelose kunye neSeluplose zihambelana nolwahluko olwahlukileyo kwiikhemikhali, iipropathi kunye nokusetyenziswa. Ngelixa i-sellulose isebenza njengecandelo lezakhiwo kwizityalo kwaye ifumane izicelo kumashishini anjenge-pilermase kunye ne-prosel seluplose, i-proses, i-methyl selupelose, i-gesmyl ye-gesieds kwimizi-mveliso eyahlukeneyo kubandakanya ukutya, amayeza, kunye nolwakhiwo. Zombini izivumelwano zibonelela ngeenzuzo ezizodwa kwaye zinegalelo kuluhlu olubanzi lweemveliso kunye nezicelo, kunye nesellulose ukuba zizixhobo zendalo ezizinzileyo nezine-methyl selsulose ebonelela ngokusebenza kakuhle kunye nokusebenza kwizicelo ezithile. Ukuqonda ukungafani phakathi kwe-methyl seluplose kunye nesellulose kubalulekile ekusebenziseni le mijikelezo ngokufanelekileyo ngelixa kuncitshiswa impembelelo yokusingqongileyo.
