The role of cellulose in concrete
Cellulose fiber is a new type of special fiber for concrete durability developed after chemical synthetic fiber. It is called the third generation of special fiber for concrete in the engineering field. It is made of a special plant species in the alpine region through a series of unique chemical treatment and mechanical processing. It has the characteristics of natural hydrophilicity, high strength and high modulus. Artificially crafted to give the surface
Determination of furfural content
Determination of furfural content The determination of furfural
The company was approved by the State Planning Commission for project approval in 2013; in December 2013, the new factory started construction; in 2014, Shenxian Shuiyuan New Energy Technology Co., Ltd. was formally established. Is the company a subsidiary of Shenxian Shuiyuan, mainly responsible for foreign trade business. It mainly produces
Preparation method of hydroxyethylcellulose
1. Alkali cellulose is a natural macromolecular substance. Each fiber ring contains three hydroxyl groups. The most reactive hydroxyl groups react to form hydroxyethylcellulose. Soak raw cotton linters or fine pulp in 30% liquid alkali, remove and press after 30 minutes. Squeeze until the ratio of alkali to water is 1:2.8, then grind. Put the pulverized alkali cellulose into a reactor, seal it, evacuate it, fill it wit
The role of hydroxyethyl cellulose in latex paint
Hydroxyethyl cellulose is the most commonly used thickener in latex paints. In addition to thickening latex paint, it can also emulsify, disperse, stabilize and retain water. It is characterized by remarkable thickening effect, good color development, film forming and storage stability. Hydroxyethyl cellulose is a non-ionic cellulose derivative that can be used in a wide pH range. It has good compatibility with other materials in th
The Difference Between Hydroxyethyl Cellulose and Hydroxypropyl Methyl Cellulose
1. The characteristics are different Hydroxypropyl methylcellulose: white or white fiber-like powder or granules, belonging to various non-ionic types in the cellulose mixture, this product is a semi-synthetic, inactive viscoelastic polymer.
Chemical Properties of Dibenzoylmethane
Dibenzoylmethane (Dibenzoyl Methane, abbreviated as DBM) is an aryl meta-diketone, a derivative in which the hydrogen on the methyl group of acetylacetone (acac) is replaced by a phenyl group. Obtained from benzylidene acetophenone by bromination and hydrolysis, colorless orthorhombic flaky crystal, easily soluble in chlorohydrin and chloroform, soluble in sodium hydroxide solution, insoluble in sodium carbonate solution,
Furfural production big country - China
China is a big agricultural country. In 2021, the corn output will be 270 million tons, and the annual corncob output will remain at about 55 million tons. Corncobs, as a kind of agricultural waste, were once mostly used as farm fuel. In recent years, with the continuous progress of science and technology in my country, the field of deep processing of corncobs has been continuously expanded, and a series of high value-added products such as

As a new type of PVC auxiliary heat stabilizer, it can absorb ultraviolet light above 290nm, with high light transmittance, non-toxic and tasteless, it can be mixed with solid or liquid calcium/zinc, barium/zinc Used together with other heat stabilizers, it can improve the initial coloring performance, transparency and long-term stability of PVC, effectively improve the "zinc burning" p
Dissolving method of hydroxyethyl cellulose
Hydroxyethylcellulose is insoluble in propylene glycol and glycerin, and only slowly dissolves in water. First disperse the hydroxyethyl cellulose in high-speed stirring alcohols, then add it to high-speed stirring cold water, and gradually heat up. All water-soluble cellulose is pre-dispersed in a water-soluble organic s
Quickly evacuate the personnel from the furfural leakage contaminated area to a safe area and isolate them, strictly restricting access. Cut off the fire source. It is recommended that emergency personnel wear self-contained positive pressure breathing apparatus and fire protection clothing. Cut off the source of furfural leakage as much as possible to prevent it from entering restricted spaces such as sewers and flood drains.
Furfural is a light yellow organic solution with a special odor similar to formaldehyde. It has a pungent odor and is poisonous.

Preparation of Activated Carbon from Furfural Waste Residue
The production of 1 ton of furfural will produce more than 10 tons of furfural wet residue. A large amount of furfural slag has been stacked in the open air for a long time, causing environmental pollution. If the slag is used directly as fuel. The slag contains a small amount of sulfuric acid, which will corrode the boiler. Because the
The use of hydroxypropyl methylcellulose
1. Construction industry: As a water-retaining agent and retarder of cement mortar, it makes the mortar pumpable. In plaster, gypsum, putty powder or other building materials as a binder to improve spreadability and prolong work time. It can be used as paste tile, marble, plastic decoration, paste reinforcement, and can also reduce the amount of cement. The water-retaining performance of HPMC prevents the slurry from cracking due to drying too quickly after application, and enhances the strength after hardening.
