Henan mine expansion demolition agent, Henan rock crushing agents wholesale price Note: 1, different types of demolition agent hydration reaction to about 24h, the expansion pressure close to the maximum, but can continue to grow by 2, the expansion pressure water-cement ratio increases with broken agent 3 large and reduce swelling broken agent pressure increases with increasing temperature 4, the expansion pressure crushing agent increases with the aperture parameters are broken object aperture / mm pitch / mm hole depth resist lines / mm Amount / (kg / m3) of soft rock crushing 35 ~ 50 400 ~ 600 H 400 ~ 600 8 ~ 10 in the hard rock crushing 35 ~ 65 300 ~ 600 1.05H 300 ~ 500 10 ~ 15 rock cut 30 ~ 40 200 ~ 400 H 1000 ~ 20005 ~ 15 plain concrete crushing 35 ~ 50 400 ~ 600 0.8H 300 ~ 400 8 ~ 10 reinforced concrete crushing 35 ~ 50 150 ~ 300 H 200 ~ 300 15 ~ 25 cloth eye design principles: center hole spacing aperture depends size and hardness of the rock, if you want the best crushing effect, before the normal construction must be pre-tested. Small aperture, the center distance will be smaller; a large aperture, the center distance will be greater, will accelerate the break time, for example: dia30 min: 35 cm (hole t0 hole), dia 35min: 40 cm, dia 40mm: 45 cm, dia 45 mm: 60 cm. Hole diameter and the crushing effect is directly related to the eyelet is too small, it is not conducive to drug fully effective; eyelets is too large, easy punching. It is recommended drill bit with a diameter of 40mm. When the body is crushed object is isolated, drilling depth of 80% to 90% broken body thickness. Hole more than water and residues with high pressure blown clean. Broken agent is a powder material with clean cold water before use thoroughly mixed. That is according to a pack of drug plus 30% to 34% water (by weight) to deploy Whey, which is about to pour stirred 1.5 L ~ 1.7 L water container, then slowly pour a bag of 5 kg fully broken agent stirred into the slurry flow, such as hand-to wear rubber gloves when mixing. The good mixing broken agent slurry quickly pour hole after drilling with slightly less than tamping rods poke poke tight, after filled immediately with a sponge or cloth head orifice plugged. During operation, all agents must be filled to 100% of the deep hole. Workers in the construction, must ensure teamwork, to do with the Chiang Khong, with the mix drugs, with drenching already steaming hot or agents shall not begin to hole filling, mix less frequently installed in order to ensure the most good construction effect, filling the hole after work is completed, arrange someone to care, unrelated persons should not be near, prevention spray Fasheng time, causing casualties. Drilling → stirring → grout → cracking (product easy to operate, approachable, you teach to use) carbatex silent expansive professional rock mining, concrete crushing agent products manufacturer, the factory has 10 years of production experience , we are very confident in their products, and for you to be able to solve problems in construction above and am very pleased.
