1. Ishishini lePetroleum
I-sodium carboxymethyl cellulose isetyenziswa ikakhulu kwi-oyile, esetyenziselwa ukwenziwa kodaka, idlala indima ye-viscosity, ilahleko yamanzi, inokuxhathisa ukungcoliseka kwetyuwa enyibilikayo, ukuphucula izinga lokubuyiselwa kweoyile.I-sodium carboxymethyl hydroxypropyl cellulose (NaCMHPC) kunye ne-sodium carboxymethyl hydroxyethyl cellulose (NaCMHEC) zizinto ezilungileyo zokwemba unyango lodaka kunye nokulungiswa kolwelo olugqityiweyo, kunye nesivuno esiphezulu se-pulping, ityuwa elungileyo kunye nokuxhathisa kwe-calcium, i-viscosity enhle yokwandisa amandla kunye nokumelana nokushisa (160 ℃) .Ilungele ukulungiswa kwamanzi amatsha, amanzi olwandle kunye netyuwa ehluthekileyo yokwemba ulwelo, phantsi kobunzima bekhalsiyam chloride inokulungiswa kwiintlobo ezahlukeneyo zoxinaniso (103 ~ 127g/cm3) ulwelo lokomba, kwaye lube ne-viscosity ethile kwaye iphantsi. ilahleko yokuhluza, i-viscosity yayo kunye nomthamo wokulahleka kokucoca kungcono kunokoi-hydroxyethyl cellulose, yizongezo ezilungileyo zokuvelisa ioli.
I-sodium carboxymethyl cellulose yi-cellulose ephuma kwi-cellulose esetyenziswa ngokubanzi kwinkqubo yokusetyenziswa kweoli, ethe yasetyenziswa kulwelo lokomba, ulwelo lwesamente, ulwelo oluqhekezayo kunye nokuphucula umthamo wokuvelisa i-oyile, ngakumbi kulwelo lokugrumba olunomthamo omkhulu, ngakumbi ukukhupha kunye nokuhlalisa kunye i-viscosification.Iselulosi yeHydroxyethyl(HEC) isetyenziselwa ukugrumba, ukugqitywa kunye neenkqubo zokufaka isamente njengento yokuqinisa udaka.Xa kuthelekiswa ne-sodium carboxymethyl cellulose kunye ne-guar gum, i-hydroxyethyl cellulose ineenzuzo zesiphumo esihle sokuqina, isanti emisiweyo eyomeleleyo, isiqulatho setyuwa eninzi, ukumelana nobushushu, ukulahleka kolwelo oluphantsi, ibloko yeglue eyaphukileyo kunye nentsalela ephantsi.
2. Ushishino lokwakha kunye nokwaleka
I-sodium carboxymethyl cellulose, Umxube wodaka lwesakhiwo kunye nodaka lokugquma, lunokusetyenziswa njenge-retarder, i-arhente yokugcina amanzi, i-thickener kunye ne-binder, kwaye ingasetyenziselwa njenge-dispersant, i-arhente yokugcina amanzi kunye ne-thickener ye-plaster, i-mortar kunye ne-flooring materials ye-gypsum kunye ne-samente. emazantsi.Ngumxube okhethekileyo wamatye kunye nodaka lokutyabeka olwenziwe nge-carboxymethyl cellulose kwiibhloko zekonkrithi ezifakwe umoya.Inokuphucula ukusebenza, ukugcinwa kwamanzi kunye nokumelana nokuqhekeka kodaka, kwaye ugweme ukuqhekeka kunye nokuvuleka kweendonga zebhloko.Izinto zokuhombisa umphezulu wokwakha i-Cao Mingqian et al eyenziwe nge-methyl cellulose yinto ehambelana nokusingqongileyo yokuhlobisa umphezulu wezinto, inkqubo yokuvelisa ilula, icocekile, ingasetyenziselwa udonga oluphezulu, umgangatho wethayile wamatye, ingasetyenziselwa ukuhombisa umphezulu. yeekholamu kunye neetafile.
3. Ishishini lemihla ngemihla lemichiza
I-sodium carboxymethyl cellulose, i-tackifier ezinzileyo, idlala indima ekusasazeni ukuzinzisa kokumiswa kwimveliso yokuncamathelisa yemathiriyeli eyomeleleyo yomgubo, ukuqina, ukusasazwa kunye ne-homogenizing kulwelo okanye kwizithambiso ze-emulsion.Ingasetyenziswa njenge-stabilizer kunye ne-viscosifier.I-Emulsifying stabilizer isetyenziswa njenge-emulsifier, i-tackifier kunye ne-stabilizer ye-ointment kunye ne-shampoo.I-sodium carboxymethyl hydroxypropyl cellulose ingasetyenziselwa njenge-adhesive stabilizer ye-toothpaste, kunye neempawu ezintle ze-thixotropic, ukwenzela ukuba i-toothpaste ibe ne-formability enhle, i-deformation yexesha elide, i-uniform kunye ne-taste ethambileyo.I-sodium carboxymethyl hydroxypropyl cellulose ukumelana netyuwa, ukuxhathisa kwe-asidi kuphezulu, umphumo ungcono kakhulu kune-carboxymethyl cellulose, ingasetyenziselwa njenge-tackifier kwi-detergent, i-arhente yokuthintela ukunamathela.Kwimveliso ye-detergent, i-sodium carboxymethyl cellulose isetyenziswa ngokubanzi njengendawo yokuchitha ukungcola komgubo wokuhlamba impahla, i-thickener kunye ne-disperant ye-detergent engamanzi.
4. Ishishini lamayeza kunye nokutya
Kwishishini lamachiza,i-hydroxypropyl carboxymethyl cellulose(HPMC) ingasetyenziselwa njengezinto ezincedisa iziyobisi, ezisetyenziswa ngokubanzi kwi-oral drug skeleton elawulwayo kunye nokukhululwa kwamalungiselelo okukhululwa, njengento yokukhutshwa kwezixhobo zokulawula ukukhutshwa kweziyobisi, njengento yokugubungela i-agent eqhubekayo yokukhululwa, iipellets zokukhululwa eziqhubekayo, ii-capsules zokukhululwa okuqhubekayo. .Eyona isetyenziswa kakhulu yi-methyl carboxymethyl cellulose, i-ethyl carboxymethyl cellulose, efana ne-MC isoloko isetyenziswa ekwenzeni iipilisi kunye nee-capsules, okanye iipilisi zeswekile ezigqunyiweyo.Umgangatho ophezului-cellulose etherszinokusetyenziswa kushishino lokutya, kwaye zizityebi ezisebenzayo, izizinzi, izincedisi, iiarhente zokugcina amanzi kunye neearhente zokuvuthuza amagwebu kumatshini wokutya okwahlukeneyo.Methylcellulose kunyeihydroxypropyl methylcelluloseziye zaqatshelwa
I-metabolism engasebenziyo engenabungozi kwi-physiology.Ukucoceka okuphezulu (99.5% okanye ngaphezulu ubunyulu)carboxymethyl cellulose(CMC) inokongezwa ekutyeni okufana nobisi kunye neemveliso zekhrimu, iziqholo, iijam, iijeli zesikhumba, iinkonkxa, iisyrups zetafile kunye neziselo.I-Carboxymethyl cellulose enobunyulu obungaphezulu kwe-90% ingasetyenziselwa kwimiba enxulumene nokutya, njengokuthutha kunye nokugcinwa kweziqhamo ezitsha.Olu songo lweplastiki lunoncedo lwesiphumo esihle sogcino, ungcoliseko oluncinci, akukho monakalo, kunye nokuveliswa ngokulula koomatshini.
5. Izinto ezisebenzayo zombane kunye nombane
Ngenxa yobunyulu obuphezulu bei-cellulose ether, ukuxhathisa okulungileyo kwe-asidi, ukuxhathisa ityuwa, ngokukodwa umxholo ophantsi wentsimbi kunye neentsimbi ezinzima, i-colloidal elungiselelwe izinzile kakhulu, ifanelekile kwiibhetri ze-alkaline, iibhetri ze-zinc-manganese i-electrolyte thickening stabilizer.Abaninzii-cellulose ethersbonisa iimpawu zekristale yolwelo lwe-thermotropic.IAcetyli-hydroxypropyl celluloseyenza iikristale ze-thermogenic cholesteric liquid ngaphantsi kwe-164 ℃.
