V. USAGE METHOD
(1) Preparation: first of all, the Hole Diameter, the hole distance and the hole depth should be designed on the basis of material, composition, shape and requirement of the objects expecting to be cracked. the following is the conventional cracking design parameter.
PS：H-heights
(2) Allowable range of hole diameter,allowable temperature range of rock or concrete, thetemperature of water to be used and temperature of HSCA. Outside concrete iron must be cutted before use HSCA
(3) Mixing：According to the propotion of HSCA, put approximately 28-35%water into container beforehand, and add HSCA. Wear RUBBER GLOVES while stirring, or use machine to stir. If the temperature is below5℃, 40℃ water is suitable.
(4) Filling：Clean the hole forehead, neither water nor materials are allowed. HSCA can be poured dirctly intothe hole, or use the coking gun or groutingpump. Enough quantities for each hole, but do not need to jam the hole. For a horizontal hole, the hole can be easily plugged with HSCA as it reaches a clay like consistancy as it starts setting up. A slight slope makes their use much easier.
(5) Protection: Spring, Summer, Autumn do not needed. In the winder it should be covered by mat.
VI．Cautions
(1) The main component of HSCA is CALCIUM HYDROXIDE(PH≥14). Wear rubber gloves while work with it. Rinse with water, when any portion of the skin comes in contact with HSCA.
(2) Pour the mixture of HSCA into the holes within 10 minutes, otherwise fluidity and fragmentation will be reduced, and it may be blow out of the hole due to the high temperature.
(3) DO NOT look directly into any holes while filling them. Wear PROTECTIVE GLASSES while working with it in case the materail blows out of the hole and hurts workers’ eyes. Rinse with water when eyes come in contact with HSCA, or go to hospital nearby.
(4) Read INSTRUCTION carefully before use our products, and take protective measur as much as possible, in case anyone gets hurt. Connect us when anything is not clear.
VII．CONTIANER AND STORAGE
hsca(high range soundless cracking agent)ca(oh)2 have revolutionized the construction and demolition industries by offering a safer and environmentally-friendly alternative to traditional explosives. These chemical agents are used to break down structures without the hazardous risks associated with conventional demolition methods. The unique composition of hsca(high range soundless cracking agent)ca(oh)2 allows them to expand and exert pressure on materials such as concrete and rock, facilitating their controlled fracture. This innovative approach is particularly beneficial in urban areas where minimizing noise and vibrations is crucial.
