JHF polymer fiber expansion agent Bengbu expansion agent price Anhui expansion agent manufacturer

1. Product introduction
JHF polymer fiber expansion agent is a high-performance, multi-functional new material. This product is a multi-component reaction of high molecular polymers, nano-scale inorganic substances, etc. It combines the essence of foreign anti-crack, anti-seepage, corrosion-resistant, high-plastic retention materials, and is refined with three-dimensional special equipment. The product has functions such as reinforcement, micro-expansion, good plasticity, and strong crack and shrinkage resistance, and has high waterproof and crack resistance.

2. Product Technical Parameters
●Impermeability is greater than S35 ●Multi-dimensional powder form ●Moisture content ≤5% ●Fineness: 0.08mm sieve residue 5%
● Coagulation time: initial coagulation ≥ -30 min, final coagulation ≤ +120min ●MgO content ≤5.0% ●K, Na total content ≤1.0%

3. Product use scope:
JHF polymerization The fiber expansion agent can be mixed with ordinary Portland cement, slag Portland cement, composite Portland cement, etc., and is suitable for various plain concrete, reinforced concrete, prestressed concrete projects, repair projects and filling and pouring projects. It is especially suitable for structures with high crack resistance and high anti-seepage requirements, and can be used as structural self-waterproof concrete. Such as dams, anti-seepage walls, reservoirs, tunnels, sewage plants, storage tanks, waterproof and crack-resistant mortars for civil buildings, etc.

4. Dosage
                                                                                                                                                3 -12%, prepare high impermeability concrete with impermeability grade S8-S35 or above.

V. How to use
1. JHF polymer fiber expansion agent is a high-efficiency, non-toxic, harmless and environmentally friendly powdery product. It should be added together with cement, sand and stone when used. In a blender, no need to dissolve with water.
                                                                                                                                      Add the polymer fiber expansion agent, then add clean mixing water, stir evenly, the time should be controlled at 3 minutes, and the slump should be determined by trial preparation in advance.
                                                                                                                                                                                              .

4. After the self-waterproof concrete is poured, water should be stored in time for maintenance or covered with wet straw felt or black film in summer. Water conservation maintenance shall not be less than 7 days. In winter maintenance, attention should be paid to covering and insulation.

5. The transportation and vibration of JHF polymer fiber expansion agent concrete are the same as those of ordinary cement concrete. However, for self-waterproof concrete, more attention should be paid to vibrating and compacting to avoid leakage or excessive vibration. The post-pouring tape must be treated carefully. After cleaning the surfaces on both sides of the post-pouring tape, first apply a waterproof tape with mortar prepared with JHF polymer fiber expansion agent, and then fill it with concrete mixed with JHF polymer fiber expansion agent.

6. Packaging and Storage
This product is packed in a double-laminated woven bag with a film liner, 50kg ± 0.5kg per bag. Pay attention to moisture-proof and sun-proof storage. The shelf life is two years. . </p
