A brief introduction NFJ misfire fine stone concrete

Misfire misfire of fine stone concrete price no spark fine stone concrete construction of fine stone concrete coating slurry combination layer does not conform to the requirements: in primary has to deal with clean brush again on the slurry, the purpose is to enhance the cohesive force of surface and base, so this is an important working procedure, appropriate to besmear brushs slurry scheduling ( General 0. 4 to 0. Water cement ratio of 5) , brush besmear to brush to uniform shall not leak when, the area is not too big, how far mortar shop brush. Besmear brushs a first generally tend to be large, but spread mortar slow, have to brush up the slurry drying quickly, such not only can't afford to bonding effect, isolation effect instead. Also must use the brush besmear has mixed slurry, cannot adopt surface, after dry and cement water back and forth with a broom to sweep the way, because the water not divide evenly, cement dry rare not divide evenly, also affect the surface not anger fine stone concrete and grassroots bonding quality. Fuse on the precast concrete do not fine stone concrete pavement are also prone to produce empty drum, cracks, precast slab of horizontal, vertical seam must be in accordance with the requirements of structural design in C20. Filling of fine stone concrete vibrating, close-grained, laying uneven thickness of cement mortar, prone to cracks, so usually use no spark fine stone concrete pavement. So be anti-cracking measures are taken. The curing time is not enough, too early: early cement hardening, the curing in water or damp environment, fully hydrated cement particles, increased the strength of cement mortar. If in short curing time under the condition of low intensity, early used here, would be to just hardened surface layer damage and destruction, causing surface dusting, hemp pit. Not only on the surface, there are lines must carefully according to the stated earlier operation process requirement, iron float shall be used to put pressure on the number of times to operate, * hard before final set cement plastering shall not leak, wipe until The Times of grain to flatten, calender. Building technology co. , LTD. , is a collection of anti-static products research and development, production, sales and construction services in one of the high-tech chemical building materials enterprises, the main products are: NFJ metal aggregate, NFJ misfire antistatic wear-resisting surface hardening of the seam an agent, not firing mortar, no spark fine stone concrete, desulfurization dolomite, conductive powder, etc. Series of misfire anti-static floor material. Widely used in petroleum, chemical industry, coal chemical, LPG stations, explosive factory, Arsenal, arms production, assembly and other fire works need not to get angry, anti-static, such as explosion-proof security field.
