Q:What is the color of the isobutyl silane impregnant for concrete anticorrosion?
Should be substandard products, ask for inspection reports, manufacturers qualified to prove, or return.
Q:How to control the impregnation conditions to obtain the active components of the various distributions of different catalysts
The amount of active components and additives is an important factor affecting the catalytic performance of the catalyst, the active components, the amount is too small, the activity of course, with the increase in the amount of load, the activity slowly increased, but generally have When the optimum value is greater than this optimum value, the activity is almost constant, and even the metal is sintered due to the excessive load, and the activity and stability of the channel are blocked. Auxiliaries are the same.
Q:Friends, ask you a question, the capacitor of the different impregnation, capacitance What is the difference?
The impregnant determines the dielectric coefficient of the capacitor medium, which determines the capacitance and field strength of the capacitor.
Q:How to determine the load when the load is loaded
A certain amount of material by adding excess water, immersed for a period of time after the filter, calculated by the amount of material to be adsorbed by the amount of water, so as to get the saturated adsorption capacity of the material bolted (station contact TA) recommended the use of insects have resources bingyu0729 ( Station contact TA) take a certain amount of material measured its saturated adsorption volume, then this part is behind the impregnation of the precursor ...
Q:The laboratory was used as a rotary sprinkler for impregnation of the catalyst
Laboratory to buy a dip is pulling method of coating with a CNC pull device, you can set many parameters, rising and lowering speed, coating height, immersion time, the number of coating and so on. Which rise and fall speed can reach 1um / s,
Q:Dipping method and precipitation method to prepare the catalyst
The non-roasting catalyst is easily lost with the solution
Q:How to do the best volume impregnation to prepare a supported catalyst?
Take a certain amount of material measured its saturated adsorption volume, then this part is in the back of the impregnation of the precursor solution, it can not be used to be lost? The amount of catalyst used to do not measure the saturation adsorption volume with water immersion carrier , After the completion of the carrier can also be used. Drying (station contact TA) You may have a problem with this system, CeO2 part of the water, PtCl2 aqueous solution is strong acid, the carrier will dissolve!
Q:What is the silane impregnant
Silane impregnant is a high performance silane product for the anticorrosive effect of reinforced concrete structures on concrete surfaces such as isobutyltriethoxysilane DB-H538, isooctyltriethoxysilane DB-H580, etc. ( China Daoer chemical industry can provide professional). Are relatively stable small molecular structure, painted to the concrete ...
Q:The use of silane impregnants
Silane impregnation simply means that the concrete surface is silane sprayed, first explaining what is silane. In the general seawall project, inland saline soil, freezing and thawing damage more serious, harsh environmental engineering are required to do the concrete structure of the silane impregnation anti-corrosion construction, the silane referred to here generally refers to isobutyl (alkene) triethoxysilane DB-H538 (liquid) search and isooctyl triethoxysilane DB-H580 (paste), and the content requirements are relatively high, respectively, requirements for more than 98.9% and 80%.
Assister, is specialized in the production of rubber vulcanization accelerator (NA-22 (ETU), ZDC, TMTM, MZ, BZ, PZ,), rubber antioxidant MB, antioxidant MMB and antioxygen 2246. Our company takes "quality first, credit superiority, to be No.1" as quality principle and welcome to cooperate with parnters all over the world.
