丹强丝
DSF (聚丙烯纤维 PP fiber)
|
|
丹强丝一种以聚丙烯为原料，以特殊工艺制造的高强度，低延伸性聚丙烯纤维，可以有效地控制混凝土
塑性，干缩、温度收缩裂纹的产生，改善混凝土的抗渗性能，抗冲击能力，延长混凝土制品的使用寿命
。
The DSF is a high strength for regarding polypropylene as raw material,with special craft
making,fiber of low extension polypropylene,and can avaylably control the concrete,and
fuck,temperature to contract the produce,improving of crack the concrete′s anti the
function,anti to pound at the ability,extension concrete the service life that product. |
主要作用：
1．提高混凝土抵抗拉伸变能力，预防和防止混凝土中各种
裂缝的出现；
2．提高混凝土的抗渗透能力；
3．改善混凝土韧性与抗冲击性，搞冻融能力；
4．使喷射水泥砂浆回弹减少。
|
MAIN FUNCTION：
1． Increase the concrete to resist to pull to stretch to transform the ability,prevention with prevent the concrete inside the emergence of the every kind of crack.
2． The anti-that increase the concrete permeates the ability.
3． Improvement concrete the tenacity and anti-pound,anti-pound to melt the ability.
4． Make jet the cement sand the thick liquid back to play the decrease.
