Epoxy grout manufacturer information: grouting condensation curing time

The condensation of epoxy grout hardening time, will directly affect the construction quality of epoxy grout. Strictly control the product quality of epoxy grout is always has pay attention to my company, in short, solve the problem encountered in the construction, for the customer service in major construction unit. For the structure reinforcement repair has a wealth of experience! Extensive use in industrial and civil building, but also widely used in roads, Bridges, railway, water conservancy and national defense construction and other major infrastructure projects related to the national economy and people's livelihood. Epoxy grout with excellent mechanical strength and economic applicability, is the foundation of most industrial and civilian floor material. Floor coating for cement floor coating engineering. The composition and principle of curing epoxy, epoxy grout grout is a kind of powdered solid material, when it is mixed with water at room temperature by the steric (physical) chemical, can by plasticity slurry body gradually condense sclerosis, into a sharp stone shape body, so the epoxy grout is a good mineral gel material. Epoxy grout can be bulk materials such as sand, stone, or brick block material cementation for whole, it could in the air like lime and gypsum setting and hardening, also can better hardening in the water, maintain and improve its intensity, so it belongs to the water rigid gelled material segment. Many varieties, classification of epoxy grout multifarious, according to the composition can be divided into Portland epoxy grout, aluminate epoxy epoxy grout grout, sulfate and phosphate, iron aluminate, fluorine aluminate, no clinker epoxy grout, such as epoxy grout varieties. With silicate series epoxy grout and among them the most widely used, for a variety of common construction projects. Industrial floor coating materials mainly for the condensation of epoxy grout hardening silicate is divided into the following phases: (1) the initial period in the early hydration reaction, because of the natural gas hydrates is small, with natural gas hydrates film layer of epoxy grout is separation between particles, mutual attraction is small, the epoxy grout slurry with good plasticity. General exothermic reaction rate of 168 j/g, h, lasts for 5 - - - - - - 10min。 Incubation period (2) gel film layer surrounding the epoxy grout grain growth, formation of point contact between each other, constitute a loose network structure, make the epoxy grout slurry part starts to lose the liquidity and plasticity, at this time as the initial setting, but this also does not have the strength. Exothermic reaction speed of 4. 2 j/g, h, duration of 1 h. (3) condensation gel film rupture ( Due to the internal moisture infiltration film speed is greater than the natural gas hydrates outward through the membrane layer diffusion speed and the osmotic pressure) Further hydration, epoxy grout particles, and make the reaction speed, until the new gel to fix broken film so far. Exothermic reaction rate gradually increased to 211 within 6 h/g, h, duration of 6 h. (4) the hardening phase formation of the gel to fill that gap between particles further wool stoma less and less, make the structure more closely, epoxy grout paste strength and gradually stepped into the stage of hardening. Exothermic reaction rate gradually reduced to 4 within 24 h. Duration of 2 j/g, h, 6 h to several years. After a long time, A few months or even years) Hydration, most of the particles are still remaining has not yet been hydration of the kernel. Epoxy grout stone is, therefore, hardened by gel, not hydration epoxy grout particles and the heterogeneity of pore structure. The main factors influencing the epoxy grout condense sclerosis are: epoxy grout of clinker mineral composition and epoxy grout, fineness of gypsum, mixing with water, coagulation admixtures, curing time, Age) , temperature and humidity, etc. Too little gypsum content must be appropriate, not retarding action; Content too much, too much calcium sulfate by ionization of Ca2 + to produce strong cohesion function, cause coagulating effect, and too much content, the late generation calcium rocky stone will cause the expansion of the epoxy grout stone. Introduce company developed a series of new high-tech environmental protection building materials manufacturers, is the collection research and development, production, sales and service entity company, after ISO90012008 of quality system certification. In order to improve the science and technology, environmental protection products of the company and reasonable solution for the purpose of the customer, integrity is the marketing idea, harmonious win-win occupy the market as the guidance, win customers, the company is committed to the production building products, i. e. , concrete admixtures, bearing epoxy grout, pipe grouting agent, the pressure of slurry, special building materials masterbatch, engineering reinforcement and repair material, steel structure and foundation of secondary grouting, concrete additive, building structure glue, interface agent, etc. The company to product quality to win the market, by the high quality service to win customers, marketing network all over the country more than 20 provinces, municipalities soon, widely used in electric power, metallurgy, petrochemical, Bridges, housing market project, etc.
