How to identify the quality of cement rods produced by China's tower network?
"Q", the main source is the cement manufacturer's production process, that is, whether the formal, the production process is advanced, at present, many illegal building materials on the market cement products from the small shaft kiln quite a lot, but Is the very unstable, is the public enemy of the enemy 4 "cut" is the life of this step to see the length of cement pole, cement is also a shelf life, in general, more than a month of cement strength is a decline, Tears of the cement is the fingers of sticky cement powder when there is a rough feeling that the cement is thicker, not normal, the use of low strength, poor viscosity cement pole quality is good or bad will affect a cement The development of the rod manufacturers, the Chinese tower network to ensure the quality of cement poles at the same time need to put the lowest price of cement pole, cement pole quality and safety related to the future development, but also related to the smooth flow of farmers
"smell", where the "smell" is "listening" means, Cement ingredients, and thus infer the quality of cement poles, at present, some small domestic cement plant for low-cost sales, violation of cement standards, excessive use of cement mixed materials, not strictly in accordance with the standard ratio of raw materials, product performance Can be imagined, the regular manufacturers of cement raw materials listed on the listing of the rigorous, the production of cement with a condensing time is moderate, durable Good features 3
1: "look", from the outside, you need to look at the quality of packaging, and whether it is the use of moisture-proof performance is easy to damage woven bags, to see whether the logo is clear, complete, usually, the regular manufacturers of cement poles should have The following contents, registered trademarks, origin, production license number, the implementation of standards, packaging date, factory number, cement varieties, low quality cement pole will affect the quality of cement pole, and need to observe the cement pole Color, in general, the normal color of the cement pole should be presented in gray, the color depth will appear more impurities 2
