Thickening is an important modification effect of cellulose ether on cement-based materials. The effects of cellulose ether dosage, viscosity meter rotation speed, and temperature on the viscosity changes of cellulose ether modified cement slurry were studied. The results showed that as the content of cellulose ether increased, the viscosity of the cement slurry continued to […]
Flexible epoxy coating provides commercial infrastructure with up to four hours of fire protection. PPG announced the launch of PPG STEELGUARD 951 epoxy intumescent fire protection coating in the Americas. This innovative product is designed for advanced manufacturing facilities, including semiconductor plants, electric vehicle battery facilities, data centers and other commercial infrastructure. After a successful launch […]
The water solubility of cellulose ether depends on the type of etherification group and its degree of substitution (DS), and may also be affected by the production process. 1.Types of etherification groups: Cellulose ethers can be monoethers or mixed ethers, and their properties vary to some extent. Low substituted hydrophilic groups, such as hydroxyethyl groups, […]
1.Adulterated Hydroxypropyl Methyl Cellulose (HPMC) is different from pure hydroxypropyl Methyl Cellulose (HPMC). Appearance: Pure Hydroxypropyl Methyl Cellulose (HPMC) looks fluffy and has a small bulk density, ranging from 0.3-0.4g/ml; The adulterated Hydroxypropyl Methyl Cellulose (HPMC) has better fluidity and a heavier feel, which is significantly different from the appearance of the genuine product. Condition: Pure Hydroxypropyl Methyl Cellulose (HPMC) powder is fibrous […]
Making concrete requires a precise mix of cementitious materials, aggregates of various sizes, water, mineral additives, and specific chemical admixtures. This complex process involves determining the right proportions, mixing, compacting, and molding, finally allowing the concrete to harden into a solid stone-like structure. In actual production and construction, the concrete ratio is crucial. By accurately determining […]
Dry-mixed mortar is a new type of building material combined with cement, fine aggregate, fly ash and other mineral admixtures and water-retaining and thickening materials, which has the advantages of stable quality, variety, and ease of construction, and it replaces the traditional mortar with its excellent performance. Raw materials are the main factors affecting the […]
1 The difference between dry mortar and traditional mortar One of the significant differences between dry mortar and conventional mortar is the use of small amounts of chemical additives for modification. If one additive is added to a dry mortar, this is referred to as primary modification; if two or more additives are added, this […]
1 On the setting time of concrete Initial setting: The initial setting time is required from the cement is mixed with water until the slurry begins to lose its plasticity. Final Setting Time: This is the time required for cement, after being mixed with water, to fully lose its plasticity and start to harden and […]
In construction, starch ethers and cellulose ethers are key additives that enhance the properties of mortars. Though they have distinct characteristics, using them together can significantly improve mortar performance. What Are Starch Ethers? starch ethers is a polysaccharide polymer compound composed of glucose, with two types of molecules, straight-chained and branched, known as straight-chained starch […]
Putty powder is a kind of building decoration materials, the main ingredients are talcum powder and glue. Just purchased the blank house surface of a layer of white is putty, usually putty whiteness in more than 90 fineness in more than 330. Putty is used to wall repair a substrate, for the next step in […]
