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

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
Introduction of dibenzoylmethane
Dibenzoyl methane is a non-toxic, 1. 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"
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.
A brief introduction to furfural
Furfural is a light yellow organic solution with a special odor similar to formaldehyde. It has a pungent odor and is poisonous. Furfural is an excellent organic solvent, and it is widely used in refining lubricating oil, improving diesel quality, refining animal and vegetable oils, and making resins and waxes. Furfural is also widely used in medicine, preservatives, fungicides, rust removers and cosmetics industries.
Shandong Hanteng International Trade Co., Ltd. (affiliated to Shandong Water Source New Energy Technology Co., Ltd.) is a professional export-oriented company with a history of many years, mainly engaged in Dibenzoyl Methane (DBM), Furfural, Hydroxyethyl Cellulose (HEC). As one of the largest
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.
Uses of hydroxyethyl cellulose
Hydroxyethyl cellulose is a non-ionic water-soluble cellulose ether product, which is widely used in architectural coatings, petroleum, polymer polymerization, medicine, daily use, papermaking and ink, fabric, ceramics, construction, agriculture and other industries. It has the functions of thickening, bonding, emulsifying, dispersing and stabilizing, and can maintain water, form a film and provide a protective colloid effect. It is easily soluble in cold
Furfural waste for soil improvement
Furfural waste residue is strongly acidic, contains a large amount of organic matter, and also contains nutrients needed for plant growth-nitrogen, phosphorus and potassium, which determines that this waste residue may become a cheap and effective amendment for improving alkalized soil. The actual results show that when furfural waste slag is used as the main agent, gypsum and
