Product Overview

Description

Description:

Concrete permeable template cloth structure is divided into layer of surface layer, layer, layer adhesion. Concrete permeable template cloth principle of work: pouring concrete, concrete, concrete in the internal pressure of cloth of water template capillary action and earthquake under the joint action such as good dao, concrete, the bubble and the some of the free of water to the surface by concrete internal migration, and through the concrete permeable template cloth from, and create the intermediate results:

(1) can reduce the component surface concrete bubble, more compact concrete;

(2) the concrete can be made part of the water from cement particles and stay in concrete to head, in which several mm deep concrete surface water-binder ratio was significantly lower;

(3) make component surface form a layer of rich in calcium silicate hydration to the density of the hardening layer. Greatly improving the concrete surface hardness, wear resistance, crack strength, make cold sex, make the permeability of concrete carbonation depth, and chloride diffusion coefficient is also significantly reduce;

(4) reduce the internal and external concrete 

 

Direction :

1. Clean formwork

 

Use wire brush or sand paper to remove rust and impurities on formworks, and wash it with water, then use clean towel wipe it to make sure formworks clean and dry. And keep the formworks smooth and level.

 

2. Cut formwork liner

 

Cut formwork liner based on your formwork size, keep formwork liner 5cm~10cm more than the edge of your formwork.

 

3. Spray glue on formwork

 

Spray glue on the surface of formwork evenly, the glue quantity should be 100~200gsm, the joint and perforate area should be sprayed glue a little more.

 

4. Stick formwork liner on formwork

 

Stick the furry surface of formwork liner on the formwork, the smooth surface of formwork liner should face to concrete. Shove the formwork liner from centre to all around, make sure the formwork bonded with formwork and make sure there is no winkles, if there is winkles please tear it and stick again. After stick formwork liner with formwork smoothly, compact formwork liner with formwork by rolling.

 

5. Splicing of two formwork liners

 

Put two pieces of formwork liners 5cm overlapping, cut off the middle of overlapping liner, take away the cutting off formwork liner, press the joint area. And spray a little more glue on the joint area, make sure the joint area connected and no gap.

 

6. Inspection

 

Inspect whether the formwork liner adhere with formwork firmly or not, make sure there are no wrinkles and bubbles on the surface of formwork liner. Lay up it 24 hours, let glue dry by airing.

 

     1.Quality requirements:

 

1)       Train the operating labors

 

2)       Stick formwork liner in days without rain, temperature from 10~40°C

 

3)       Normally, formwork liner can be reuseable 2~5 times. Inspect the formwork liner before reuse it, if the fabric has been blocked by slurry, then the formwork liner can not be use any more.

 

4)       Protect formwork liner during construction process. Once formwork being damaged, cut and remove the damaged liner, clean formwork of that area, and stick new formwork liner in that area.

 

      2. Safety precautions:

 

1)       No smoke and no fire while spraying glue, to avoid explosion of glue cans.

 

2)       If install formwork and dismantle formwork need be operated aloft, please refer to the aloft work relevant regulations.

 

      3. Special notes:

 

1)       Keep out edge: make sure the edge of formwork liner 5~10cm more than formwork, easy to excessive water drain out.

 

2)       Big size formwork or difficult water discharge formwork should be opened a 5mm hole in the centre of formwork, to make sure excessive water drain out.

 

3)       Avoid vibrating needle contact with formwork liner and damage it.
