special effects duang ~ Sisiyuan polypropylene fiber in cement foam plates
Special effects Sisiyuan polypropylene fiber in cement foam plates, better than not know, a more than to know, enlightened, a look surprised. Let's take a look polypropylene fibers which have cause for envy, jealousy, hate and inherent superior characteristics it!
Polypropylene fiber properties
■ most light: density 0.91g / cm3, the smallest of the five-lun, about 34% lighter than polyester;
■ most warm: heat rate 36.49%, the highest five-lun, polyester is 1.7 times;
■ most hydrophobic: Regain almost zero, the hydrophobic moisture - the best performance.
"Three most" really is not blowing, silver home is genuine it! Do not believe, you see the pictures!

Some people say, polyester fibers can also be used in cement foam board, the effect is not bad. That we come to compare chant!
Polypropylene fibers and polyester fibers in the cement foam board in contrast the advantages and disadvantages:
Polypropylene fibers
1. The proportion of light, close to the density of water, easily dispersed uniformly in the foam board;
2. The non-absorbent, based on the characteristics of cement will crack, will not dry cement in the water, slow crack;
3. theoretically calculated, the same weight, the number of polypropylene fiber polyester fiber far greater than the number, the more enhanced the cohesion of cement foam board;
The advantages of better insulation effect, reduced our holding costs.
Polyester
1. The proportion of heavy, too soft, easy to disperse in the cement foam board, causing the fibers can not be evenly distributed foam board, you can not play a real role in cracking;
2. easy to absorb water quickly absorb the cement foam process water, greatly increasing the likelihood of fracture;
3. The use of polyester fiber, the surface uneven cement foam board, easy to crack.
This time is secure in it! Love polypropylene fiber cement foam board. Others want concubine? ? No, cement foam board as long as one child is enough polypropylene fiber of it! Meme da!
