    A project can make money, and the focus is on data cost control. In fierce competition, the use of large price wars, there will be opportunities for low-priced products, your prices are not balanced, low-priced I am low, manufacturers make every effort to reduce costs. White materials Polyurethane materials are made of different types of additives, additive formulas, good or bad. Several servings have a direct impact on the cost and quality of the data. For example, the number of flame retardants can be reduced, the cost can be reduced, and the flame retardant grade Also came down, grade or to the information came out. After the fire hazard, even if there is no problem during the construction process, the fire will start after the fire, and the result will be more serious. I advocate that companies not only need to think about capital and choose cheap materials, but also ignore the risk of the next day. As the saying goes, "cheap, no good" is cheap, and the cost must be low. If the quality of other auxiliary materials is not good, or there are no copies, it will directly affect the foaming quality, such as foaming rate, cure rate, water absorption rate, bond strength, dimensional change rate index, and appearance strength. Seriously, a single foaming speed will greatly affect the efficiency and effectiveness of the foam if you do not meet the construction environment during the construction time. Spray guns, two guns do not love foam, gunners do not like to stand here waiting for direct spraying three or four times, and the response is hot Super thick. If fast curing, from the hair, once cured (mainly more than the number of copies of the curing agent), the boss may not see the phenomenon of material quality problems, but the result is a substantial increase in the cost of information. The bad black substance seems to be foaming, no problem, but the black material is not good, it will affect foaming, mobility, adhesion, dimensional stability, and density increase. The appearance of these problems naturally increases the cost. Therefore, cost control is not only the pursuit of low-priced flame-retardant products, but management should be stopped in many ways.
    Ten factors affect consumption of polyurethane spray:
    Density: Density is also called bulk density. It is a performance index of rigid polyurethane foam, which directly affects the density of the foam. The density is too large, the foam volume is small, and the density is too low. Although saving data, it changes other performance indicators and affects quality. Controlling with proper density indicators is an element of the province.
    : Thickness: spray polyurethane foam spray gun, spray, can control the number of times in foam molding and spraying, control the thickness of the data to save some benefits.
    : Angle: The angle coefficient is also large. On the one hand, the spray can be sprayed vertically at reasonable intervals, which has a great advantage in controlling the shape and thickness of the spray.
    , Temperature: polyurethane foam is the reaction of heat and gas, chemical reaction requires sufficient heat. But when the temperature is low, the reverberation heat of the foam is absorbed by the base wall. Some cannot be sent in anymore. It is also caused by the ambient temperature, and then the surface foam does not respond well. To have a good foaming effect, data temperature, substrate temperature, and ambient temperature are very important.
    Data: Good foaming speed must be suitable for the climate at the time, foaming speed is not too fast, curing speed is too slow, foam activity, slow foaming during manual spraying operation, and the number of times of ultra-thickness flatness improvement from time to time. It is also important to document the formulation and the performance qualities of the various ingredients.
    : Equipment: The quality of the equipment mainly depends on the heating continuity of the equipment and the level of failure rate of the mixed data.
    Hand spraying: The strength of the sprayer's entire process is built in the sprayer. It is not that he can control the weather and related information, but he must know what aspects are appropriate for the construction. Only in this way can the degree sprayer dry the well. It is also important to develop a good sense of obligation.
    , Scaffolding and construction: the frame angle is higher than the basket, the labor intensity of the radiant hand, or the basket has more labor, the construction efficiency is higher, but the construction of scaffolding in some coastal cities or commercial areas is relatively suitable, it can effectively prevent Network congestion of wind and avoiding environmental pollution from bubbles.
    2. On-site acceptance: spray polyurethane foam is a kind of free foaming, and its thickness is difficult to control
