Sodium carboxymethyl Cellulose (CMC) est anionic, recta torquem, aqua-solutum Cellulosa aether, inde naturalis cellulosa et chloroacetic acidum a eget. Its aqueous solution has the functions of thickening, film forming, bonding, water retention, colloidal protection, emulsification and suspension, and can be used as flocculant, chelating agent, emulsifier, thickener, water retaining agent, sizing agent, film forming material, etc., which is widely used in food, medicine, electronics, pesticides, leather, plastics, printing, ceramics, daily eget industria et aliis agris.

Sodium carboxymethyl cellulose is generally a powdered solid, sometimes granular or fibrous, white or light yellow in color, no special odor, is a macromolecular chemical substance, has a strong wettability, can dissolve in water, in water to form a viscous solution with high transparency. Insolubilis in generali Organici solutions, ut ethanol, aether, chloroform et benzene, sed potest dissolvi in ​​aqua, directe dissolvi in ​​aqua est relative tardus, sed solubility est adhuc valde magna et aqueus solutio est tamen valde magna et aqueus solutos est adhuc valde magna et aqueus solutos est adhuc valde magna et aqueum solutos est tamen valde magna et aqueus solutos est adhuc valde magna et aqueus solutos est adhuc valde magna et aqueum est quodammodo, et aqueum est admodum et aqueum est, et aqueum est quodammodo et aqueum est quodammodo. Solidum in generali amet est firmum, quia habet quaedam aqua effusio et humiditas, in sicco environment, potest servari diu.

① Production

I. Aqua mediocribus modum

In aqua, carbo processus est relative mane productio processus in industriae praeparatio sodium carboxymethyl cellulosose. In this process, the alkali cellulose and etherifying agent react in an aqueous solution containing free oxygen oxide ions, and water is used as the reaction medium in the reaction process, without organic solvents.

II. Solvendo modum

Solvendo modum est organicum solvendo modum, quod est productio processus developed in ex aqua medium modum ad reponere aquam cum organicum solvendo ut reactionem medium. A processus of alcalization et Afferation of alkali Cellulose et monochloricaacetic acidum in organicum solvendo. Secundum moles reactionem medium, potest dividitur in egenis modum et swimming slurry modum. In moles organicum solventum in Polping modum est multo maior quam qui de egestate modum, et moles organicum solvendo usus est in stolens modum est ratio organicum solvendo in Polping modum est ratio in volumine solvendo in Polping quantum est Ratio est in solvendo in Polping. Cum sodium carboxymethyl cellulosis est paratus a swimming slurry modum, in reactionem solidum est in slurry et suspensionis statum in system, ita natantes slurry modum etiam dicitur suspensionis modum.

III. Slurry modum

Slurry modum est tardus technology ad producendum sodium carboxymethyl cellulosose. Slurry modum potest non tantum producendum excelsum puritatem sodium carboxymethyl cellulosa, sed etiam producendum sodium carboxymethyl Cellulose cum altum substitutionis gradu et uniformis substitutionis. Productio processus de slurry modum est dure ut sequitur: quod bombacio pulpam, quod fuit in pulveris est ad verticalem alkalizing apparatus instructa cum isopropyl alkalized est adiunxit cum mixtio est alkalized et alkalizing est de XX ℃. Post alkalization, in materia est exantlaretur ad vertical ethering apparatus et isopropyl ipsum Vocatus solutio Chloroacetic Acidum est additum et adherentes temperatus est de LXV ℃. Secundum specifica uber usus et qualitas requisita, alcalization concentration, alkalization tempus, moles etheringing agens et exherere et alia processus et alia processus parametri potest esse adaequatum.

② application scope

I. Non solum bonum emulsifying stabilitor et Thickener in cibum applications, sed etiam habet optimum frigore et liquescens stabilitatem, et potest amplio productum saporem et extend repono est.

II. In purgat, CMC potest esse quod an anti-fouling redeposition agente, praesertim ad Hydrophobic synthetica fibra fabricae anti-fouling redeposition effectus, significantly melius carboxymethyl fibra.

III. In oleum EXERCITATIO potest ad protegendum oleum Wells ut luto stabililer, aqua retentione agente, quantum cuiusque oleum bene sit II ~ 3t vadum Wells, altum V ~ 6t.

IV. In textile industria quoddam agente, printing et tincta slurry Thickener, textile printing et rigor metam.

V. Usus est ut membrana anti-settling agente, emulsifier, dispersant, adtritio agente, tenaces, potest facere solidum pars in pingere aequaliter distribuit in solvendo, ita ut pingere non stratified in tempore, ut in puty.

VI. Sicut flocculant in remotionem calcium iones quam sodium gluconate magis efficaciora, ut cationis commutatio, in commutationem facultatem ad 1.6ml / g.

VII. In charta industria usus est sicut charta sizing agente, potest significantly amplio arida vires et infectum viribus chartam et oleum resistentia, atramento effusio et aquae resistentia.

VIII. Sicut hydrosol in stibio, usus est sicut crasso agente in toothpaste, dosis est circiter V%.
