Rock crushing agent Fuzhou, Fuzhou concrete expansion for reinforced concrete crushing demolition agent Jiaze SCA Soundless cracking Agent carbatex silent expanders (referred carbatex SCA broken agent) compared with zhayao, its crushing effect of low, long crack occurrence time But many occasions that it is not suitable for use zhayao zhayao best alternative helper. In developing mine construction program, for large, complex when mining is mainly used carbatex SCA broken agent, consider using joint means machinery, or with the control baopo cooperate to improve work efficiency, better reach break purposes. First, drilling construction in rock drilling machines and drilling mainly uses air (Machinery market, many, factory in certain areas there are agents of machinery to co-operate, can assist you in sourcing advisory). Second, stirring method carbatex SCA agent is usually broken bag of 20kg, plus the amount of water is 30 to 35% by weight of broken agent Jiaze SCA, which was added 1. 5 ~ 1.7kg clean water. Add water with the temperature and carbatex SCA broken agent models, the adjusted within the above range. Jiaze SCA broken agent slurry is smooth inflow hole prevail, not more water, otherwise it will reduce the crushing effect and the effect of the indefinite extension of the reaction time. While stirring, first a good amount of water into the bucket, then pour into carbatex SCA broken agent, then start the hand blender to mix evenly, stirring time is generally 40-60s. Small occasion when stirred by a human, to wear rubber gloves, hard Bancheng "club" like paste, be sure to stir without lumps. If left in the bottom of the barrel of carbatex caking agents SCA broken, you should always clean out. Jiaze caking agents SCA broken long home will reduce its performance should not continue to use. During the construction temperature is below 10 ℃, use 40 ~ 50 ℃ hot water with stirring to accelerate the rate of hydration carbatex SCA broken agent. General common winter. Third, the grout mixing well carbatex SCA broken agent slurry to run out in less than 10min. Because of its rapid loss of fluidity, long home to make the grout difficult and long in air easily volatile product potency and thus lose effectiveness. 1. For vertical holes can be directly poured into it, and pound with a thick wire inserted. This avoids too full, the waste material; avoid filling not dense, and reduce the crushing effect; orifice may leave about 5mm gap as well. 2. For horizontal holes, in order to prevent the slurry back out, use water-cement ratio of 0.25 to 0.28 of water and carbatex SCA broken agent mixed into clay, hand twisted strip, into the hole, then sticks pound compacting pressure. Waterproof bags, etc. may also be purchased after loading stuffed hole. Jiaze SCA broken agent fill level hole inclined holes is also very convenient. Slant-hole situation with respect to the horizontal hole is easier to operate and to grasp the free surface and other issues. 3. Rows of holes. For large volume of rock crushing, mostly using plum-shaped rows of holes. In the periphery of the hole near the free surface, easy to crack, but the middle of the hole by four weeks limit, cracking difficult. Therefore, when filling carbatex SCA broken agent, there must be a certain "time difference" before filling the edge of one or two rows of holes, the 10 - 20h, reperfusion three or four rows of holes, more than so forth. The principle of "from near and far, from the outside, layered graded broken." Fourth, conservation 1. In the spring, summer, after cracking agent filling carbatex SCA, is generally not covered (except rain outside), after the occurrence of cracks, can pour seam to accelerate the expansion of the role of carbatex SCA broken agent. 2. In the winter, it can be 40 ~ 50 ℃ hot water with stirring carbatex SCA broken agent, at negative temperature, you can add 1% to 2% of industrial CaCl 2, that is 50 ~ 100gCa-C1 2 was dissolved in 1500mL of water, then add a bag Jiaze SCA broken agent. After filling, use a straw or felt, and other cover insulation. V. carbatex SCA broken agent spray phenomenon and Protection 1. Jiaze SCA broken agent spray phenomenon often occurs in the following situations: carbatex SCA broken agent model (1) Select the inappropriate, such as when the low temperature with high temperature; (2) the construction temperature exceeds carbatex SCA cracking agent temperature range, summer at noon grout; (3) the aperture is too large; (4) the quality of carbatex SCA demolition agent in question (in this case generally a very small chance, because our products are seasonal production, distribution of different customers and I plant has more than 10 years experience, experienced, skillful). 2. The reason Jiaze SCA broken agent spray phenomenon, mainly due to a large amount of heat of hydration Jiaze SCA hydration when broken agent and the surrounding medium heat slowly, when regenerative state surrounding a borehole reaches 100 ℃, carbatex SCA broken agent hydration water will not boil, producing steam pressure, when the pressure exceeds the bond strength carbatex SCA broken agent slurry and the hole wall will produce discharge phenomenon. VI Construction Notes 1. When Jiaze SCA broken agent construction, in order to secure the best to wear protective glasses, carbatex SCA do not close broken agent filling opening after opening look, just in case eye injury occurs spray; 2. Jiaze SCA broken agent is a basic compound, mildly corrosive to the skin, rinse skin immediately after the encounter; 3. In case Jiaze SCA broken agent orifices damage the eyes, immediately wash with water and bengsuan water. (Recommendation nearest medical treatment, the hospital cleaning, must not blind treatment). 4. Jiaze SCA broken agent should be stored in a dry place, keep away from moisture.
