Two Component Acrylic Grout Liquid Waterproof Grouting For Tunnel And Channel

 

Product Description

 Brief Introduction:

 It has been confirmed that acrylamide is toxic and pollutes environment, so, years of deep research, development and application of acrylate has been carried out. Meanwhile , BeiJing LangWei Times Science and Technology Co.,Ltd did a lot of work in this field and finally developed the second generation (AC-II) grouting liquid whose performance is much more reliable.

 

Advantages:

  1.Non-toxic: All raw material, grouting liquid and gel are non-toxic by adding new cross-link agent instead of methylenebisacrylamide in the raw materials.

 2.Environmental friendly: anti-caking ingredients in the liquid lead to a better and safer utilization.

 3.Easy grouting: low viscosity ,sound permeability make it easy to fill tiny crack with low pressure.

 4.Economical cost, easy operation: adjustable curing time and controllable grouting area reduce grouting cost, A+B components simplify grouting preparation.

 5.High anti-permeability: low Gel penetraion coefficient guarantee its excellant anti-permeability.

 6.Resistanse to water pressure:strong Gel can withstand high water pressure.

 7.Water Swelling: repeated expansion in dry and wet environment, good sealing effect.

  8.Durability:stable chemical structure, excellant endulance quality.

  Application:

  1.Mine,laneway, tunnel, channel, tunnel, culvert pipe for water stop

  2.Seepage prevention and leak stoppage for concrete crack

  3.Maintenance the concrete structural joint sealing

  4.Seepage-proofing curtain grouting of dam rock cracks

  5.Soil reinforcement

  6.Construction of shotcrete

  Product component:

  A liquid: Acrylate,accelerant

 B liquid: evocating agent,regulator

 Retarder (use it when you need control the Gel time)

 Composition of AC - II grout

 AC - II grout consists of A, B two components

 A solution includes: a double bond, can produce linear polymer monomer--acrylic; two or two more double bonds, can copolymerize with acrylic and produce mesh or bodily form polymer monomer-- crosslinking agent, and initiator; can produce accelerator of monomer polymerization initiated from free radical by the reaction with initiator; as well as antagonistic resistant agent and water.

 B solution includes: initiator and water which can trigger the above mentioned monomer polymerization. Need to delay coagulation, join the retarder which can prolong the induction period of polymerization in B solution.

 Mix A, B liquid with equal volume, stir evenly, then we get AC - II grout.

Company Information

As an member of Chemical Grouting Sub-Committee, Chinese Hydraulic Engineering Society, the Director Member of Waterproof Sub-Committee and China Construction Industry Association.LANGWEI Conchem is a fast growing international manufacturer of construction chemicals with plants in Beijing, China. The company is specialized in preventative and remedial waterproofing products. 


Preventative waterproofing products are wildly used during new construction and are usually installed by the general contractor. Examples are bentonite strips, hydrophilic mastics and rubbers, which swell in contact with water and hence block water ingress, injection hoses, which can be injected at a later stage to block water and finally cementitious coatings for basement waterproofing and elastomeric membranes for tanks and roofs.

Remedial waterproofing products are mostly used when major (or minor) water leaks happen at a later stage and are usually applied by specialist applicators. Remedial waterproofing products are also often used during construction of tunnels and other underground constructions to prevent infiltrating water from hindering the normal progress of the works. Examples are injection resins based on Polyurethanes (both 1C and 2C) and Poly-acrylates. These products are also used for Soil and Rock Stabilization, together with Organo-minerals.

LANGWEI Conchem also manufactures a series of products for the Protection and Repair of reinforced Concrete. Examples are cementitious grouts and mortars, epoxy injection resins, carbon fibre laminates and epoxy glues.
