Methylcellulose Hv Uses

Methylcellulose Hv is commonly used in the construction market as a binder for cement, mortar, joint desliming, etc. It is utilized as a movie previous and also adhesive in the cosmetic, pharmaceutical as well as food industries. Likewise used as fabric printing and dyeing sizing representative, synthetic resin dispersant, layer movie former and also thickener. Antacid cellulose is prepared from pulp, which is then reacted with methyl chloride or dimethyl sulfate in an autoclave, and afterwards refined with cozy water.
Methylcellulose Hv is utilized in thickeners; stabilizers; emulsifiers; excipients; dispersants; adhesives; movie formers, hydrosol replacements. Additionally used in mayonnaise, shortening and specific various other foods. Since this item is indigestible in the body, it can preserve a number of times of water as well as create satiation. It can be used in soda biscuits, waffles, etc to make healing food. When using, very first damp the powder with regarding 1/5 of the required quantity of warm water, after that include cold water (include ice if required) and also stir well. EEC: Authorized for icy foam items, potato chips, sodas, special dietary foods, pastry shop fillings, foam garnishes, sauces, sauces.
Methylcellulose Hv is used as artificial resin dispersant, layer film previous, thickener, building product adhesive, textile printing and also coloring sizing agent, movie previous in pharmaceutical and food industries, etc.
Methylcellulose Hv went through pulse field capillary electrophoresis on kilobase nucleotides in water down methylcellulose remedy, as well as bone marrow cells were cultured in semi-solid methylcellulose medium. In the pharmaceutical industry, it is made use of as a safety colloid and also dispersant, an extender, a stabilizing and also emulsifier, and an adhesive. The liquid suspension is neutral to litmus paper, with different kinds of molecular weights ranging from 4,000 to 180,000, generally having 25-30% of methoxy groups. Solubility: This item is soluble in cold water to create a transparent thick remedy. Due to the presence of a certain quantity of hydrophobic teams, this product is soluble in some organic solvents, as well as in combined solvents of water as well as raw material. Salt resistance: This product is a non-ionic and also non-polymeric electrolyte, so it is reasonably steady in liquid options of steel salts or organic electrolytes. Gelling or rainfall might be created in the visibility of too much electrolyte. Surface task: The aqueous remedy of this product has surface activity, as well as has the features of colloid protective representative, emulsifier and dispersant. Thermal gelation: When heated up to a specific temperature, the methylcellulose liquid remedy ends up being an opaque solution as a result of gelation or rainfall. Nonetheless, it becomes the initial solution state after slowly cooling. The temperature at which coagulation and also rainfall take place relies on the sort of product, the concentration of the option and also the home heating rate. Low ash content: Capitalizing on the thermal gel residential properties of this product, it is cleaned with warm water during the prep work process to achieve the function of refining, so its ash material is really low.

Production Method of Methylcellulose Hv

Alkali fiber is prepared from pulp, and then etherified with methyl chloride. According to various sources, pulp includes cotton pulp, wood pulp, straw pulp, etc. Wood pulp and also cotton pulp (cotton linters) are typically made use of in the sector. The cellulose in the pulp itself is hard for methyl chloride to act, as well as it should be made into alkali cellulose initially. Mix 1 part of cellulose, 0.9-1.2 parts of salt hydroxide and also 0.9-1.2 parts of water (all by weight), as well as saturate it at regarding 30 ° C for 1-2 hours. After that press to remove excess lye to get clumped antacids cellulose. It is shredded to loosen the alkali cellulose tissue and further homogenize it, and after that connect with oxygen in the air. The destruction of alkali cellulose lowers the polymerization and attains the function of changing the thickness of the product. Hereafter aging process, the alkali cellulose is suspended over methyl chloride (generally 10-15 times the weight of the pulp), and also the etherification can be finished by reacting at 60-70 ° C for about 5 hours, and the equivalent reaction stress is about 1.7 MPa. Post-processing of the item includes washing as well as drying of the ended up product. Normally, it is washed in hot water at 80-90 ° C, counteracted by adding a suitable quantity of hydrochloric acid (or sulfuric acid), and also oxalic acid is added to make it complicated with iron and heavy metals, and also it is removed together with salts such as sodium chloride during cleaning. The washed item is dehydrated as well as dried to get the ended up product of Methylcellulose Hv.

What is the Difference Between Hydroxypropyl Methylcellulose and Methylcellulose?

The cellulose ether is obtained from pure cotton fiber through alkali treatment, methyl chloride as etherification agent, and methyl cellulose MC is obtained through a series of reactions. The general degree of substitution is 1.6~2.0, and the solubility of the degree of substitution varies.
1. The water content of Methylcellulose Hv depends on the addition amount, viscosity, particle size and solubility. The addition of water is large, the fineness is small, the viscosity is large, and the water retention performance is good. In the water retention test, the addition amount had the greatest influence on the water retention, while the viscosity had no direct relationship with the water retention. The water content of methyl cellulose ether and hydroxypropyl Methylcellulose Hv were both higher.

2. Methylcellulose Hv is soluble in cold water but not easy to dissolve in hot water, and its aqueous solution has good stability in the range of pH=3~12. It has good compatibility and can be compatible with surfactants such as starch and fatty acid glue. When the gelation temperature reaches a certain level, the phenomenon of gelation occurs.

3. The change of temperature will seriously affect the ability of methyl cellulose to store water. When the temperature is above 40 ℃, the water-retention performance of methyl cellulose decreases significantly, which has a great impact on the structural properties of the mortar.

Hydroxypropyl methyl cellulose HPMC prepares a non-ionic mixed ether through a series of reactions under alkaline conditions, using propylene oxide and methyl chloride as etherifying agents. Generally, the degree of substitution is usually between 1.2 and 2.0, and the ratio of methoxyl content to hydroxypropyl content is different, and its properties are also different.

1. Hydroxypropyl methylcellulose is easily soluble in cold water, but difficult to dissolve in hot water.

2. Hydroxypropyl methylcellulose is stable to acid and alkali, and its aqueous solution is very stable between pH=2~12. Sodium salt and lime water also have little effect on its performance, but can speed up its dissolution. For general salts, hydroxypropyl methylcellulose is stable, but when the concentration of the salt solution is higher, the viscosity of the hydroxypropyl methylcellulose solution is higher.

3. Hydroxypropyl methylcellulose has better resistance to enzymes, and its enzymatic degradation ability in solution is lower than that of methylcellulose.
