1. Methylcelculose (MC)
Emva kokuba ikotoni ecocekileyo iphathwa ngeAlkali, i-Selesese i-Ersulose iveliswa ngothotho lwe-methane hloride njengearhente ye-e-hloride njengearhente ye-e-hloride njenge-arhente yokwenyama. Ngokubanzi, inqanaba lokufakwa endaweni le-1.6 ~ 2.0, kwaye i-solinoing nayo yahlukile ngamanqanaba ahlukeneyo okufaka endaweni. Yeyokutshekisha i-enic sete
. Isisombululo se-ACTEAFOOF sizinzile kakhulu kuluhlu lwe-pH = 3 ~ 12. Ihambelana ngokuchanekileyo nesitatshi, i-Gum Gum, njl. Njl. Xa iqondo lobushushu lifikelela kubushushu bendawo, ukumela.
. Ngokubanzi, ukuba isixa esongezelelekileyo sikhulu, ukulunga kuncinci, kwaye i-vickosity inkulu, inqanaba lokugcina amanzi liphezulu. Phakathi kwazo, isixa-mali songezelelo sinefuthe elikhulu kwiqondo lokugcina amanzi, kwaye inqanaba le-viscofity alikho ngqo kwinqanaba leqondo lokugcina amanzi. Inqanaba lokuchithwa ikakhulu lixhomekeke kwinqanaba lokutshintsha komphezulu wesuntswana kunye nobumdaka obuchaphazelekayo. Phakathi kwezi zinto zingentla kwe-Sethes, iMethyl Selelose kunye neHydroxypropyl Methyl Selelose anemilinganiselo ephezulu yokugcina amanzi.
(3) Utshintsho kubushushu luya kuchaphazela kakubi inqanaba lokugcinwa kwamanzi kwi-methyl seluplose. Ngokubanzi, amaqondo obushushu aphezulu, okuphezulu kokugcina amanzi. Ukuba ubushushu obuphango bungaphezulu kwe-40 ° C, ukugcinwa kwamanzi kwe-methyl seluplose kuya kuncitshiswa kakhulu, kuchaphazele kakhulu ukwakhiwa kodaka.
(4) I-Methyl Selelose inefuthe elibonakalayo kulwakhiwo kunye nokubulala. I "Dehlosion" apha zibhekisa kumandla okunetha ezibonakala ziphakathi kwesixhobo somsebenzi wesicelo kunye nodonga, oko kukuthi, ukumelana nodaka. Ukuthambelela kuphezulu, ukumelana nodaka kubukhulu, kwaye amandla afunwa ngabasebenzi kwinkqubo yokusetyenziswa inkulu, kwaye ukusebenza kodaka akunamsebenzi. I-Methyl Seledion ikwinqanaba eliphakathi kwimveliso ye-etelulose etele.
2. Hydroxypropylmethylcelose (hpmc)
I-HydroxyPOpyl Methylcelcelgalose yintlobo ngeentlobo zeselfowuni kwaye isetyenziselwe ukusetyenziswa ngokukhawuleza kwiminyaka yakutshanje. Yinto engeyiyo i-ionic ye-ionic ye-iether exutywe ye-ethet ye-cotton ehlaziyiweyo emva kokuqiniseka, usebenzisa i-propylene oxide kunye ne-methyl chloride njengearhente yokuphendula, ngokuphendula. Inqanaba lokufakwa endaweni yi-1.2 ~ 2.0. Iipropathi zayo zahlukile ngenxa yemilinganiselo eyahlukileyo yemixholo ye-APENGSYL kunye nomxholo we-hydroxypropy.
. Kodwa iqondo lokuhlaselwa layo lokuhlaselwa kwamanzi ashushu liphezulu kakhulu kune-methyl seluplose. Ukunyibilisela emanzini abandayo kuyaphuculwa kakhulu xa kuthelekiswa neMethyl Selelose.
. Ubushushu buchaphazela i-viscofity yayo, njengoko amaqondo obushushu ayanda, i-viscosity ihla. Nangona kunjalo, i-viscosity yayo ephezulu inamaqondo obushushu asezantsi kune-methyl seluplose. Isisombululo sayo sizinzile xa sigcinwe kubushushu begumbi.
.
. I-Caustic Soda kunye namanzi e-lime anempembelelo encinci ekusebenzeni kwayo, kodwa uAlkali unokukhawulezisa ukupheliswa kwayo kwaye kwandise i-viscofity yayo. I-HydroxyPOpyl Methylcelcelcelose iZinzile kwi-SECTs eqhelekileyo, kodwa xa uxinzelelo lwesona sityibilili liphezulu, i-viscosity ye-hydroxypropyl methylcelses isisombululo sithanda ukunyuka kwesisombululo.
. Ezinjenge-polyvinyl utywala, i-starch ether, i-gum yemifuno, njl.
. Ubembiso lwe-Hydroxypropyl Methylceluplose yomhlaba uphakamileyo kune-methylceluplose.
I-3. I-Hydroxythl seluplose (hec)
Yenziwe kwiCotton ehlaziyiweyo ephathwe ngeAlkali, kwaye yasabela kwi-Ethylene oxide njengearhente ye-ether phambi kwe-acetone. Inqanaba lokufakwa endaweni yi-1.5 ~ 2.0. Inombala oqinileyo kwaye kulula ukuyifumana ukufuma.
. Isisombululo sayo sizinzile kubushushu obuphakamileyo ngaphandle kweGelling. Ingasetyenziselwa ixesha elide phantsi kobushushu obuphakathi kudaka, kodwa ukugcinwa kwamanzi kwawo kusezantsi kune-methyl sellyulose.
. I-Alkali inokukhawulezisa ukuchitheka kwayo kwaye yonyusa kancinci. Ukusasazeka kwawo ngamanzi kubi kakhulu kune-methyl seluplose kunye ne-hydroxypropyl methyl sethyulose. .

I-4. I-Carboxymethyl Selelose (CMC)
I-Ionic Seleulose Ether yenziwa kwi-fibers yendalo (umqhaphu, njl.njl) aphathwa njenge-alkali kwaye isetyenziswe njenge-Arhente yoLawulo lwe-ESETHE ngoluvo lonyango. Inqanaba lokufakwa endaweni yi-0.4 ~ 1.4, kwaye intsebenzo yayo ichaphazeleka kakhulu ngumgangatho wokufaka endaweni.
(1) Ibhokisi ye-carboxymethyl seluprose ye-hygroscopic, kwaye iya kuba namanzi amaninzi xa igcinwe phantsi kweemeko ngokubanzi.
. Xa iqondo lobushushu lingaphezulu kwe-50 ° C, i-viscosity ayinakuphikwa.
(3) Uzinzo lwayo luchaphazeleka kakhulu yiPH. Ngokubanzi, inokusetyenziswa ngodaka olusekwe kwiGyppum, kodwa hayi kudaka lwesamente. Xa i-alkaline kakhulu, ilahleka.
(4) Ukugcinwa kwawo amanzi kusezantsi kune-methyl selluplose. Inefuthe lokubuyisa kwi-gyppum-esekwe ngodaka kwaye inciphise amandla ayo. Nangona kunjalo, ixabiso lebhokisi ye-carboxymethyl seluplose iphantsi kakhulu kune-methyl seluplose
