Release agent is also called concrete isolation agent or stripping lubricant. Apply to the template is a kind of wall lubrication and isolation effect, make the concrete form removal smoothly from the template, keep the concrete shape intact material. Compared with the traditional mold release material waste engine oil or engine oil, release agent is easy mold release, no pollution, no corrosion concrete surface template, besmear is simple, the price is low wait for an advantage. However, not all types of concrete release agents to use templates made of various materials, to the template of different material and different construction conditions and facing the requirements of the concrete must choose appropriate release agent, can receive good effect. Regarding the release agent selection and question on application technology is introduced as follows:

Template in the concrete surface besmear brushs release agent to reduce the cohesive force and is easy to be out of concrete and template, not because of the low early strength of concrete damage when parting, keep the concrete surface is bright and clean, at the same time can protect the template, to prevent the deformation or corrosion, easy to clean and reduce the repair cost, therefore, the release agent shall meet the following requirements:

1, good stripping performance

Open mold, mold release agent can make the template smooth away from the concrete, concrete surface smooth level off, edges and corners and tidy condition.

2, coating is convenient, quick ChengMo, easy to clean after ripping

Release agent as well to coating and spraying, ChengMo faster (20 minutes)

After mold is easy to remove, such ability does not affect the construction progress and productivity.

3, without affecting the concrete surface decoration effect concrete surface without dipping imprint, the yellow color

4 steel, no pollution, harmless to the concrete

Not affect the grip of concrete and reinforcing steel bar, do not change the setting time of concrete mixture, should not contain any harmful substances on concrete performance.

5, protection template, prolong the service life of the template

Block with release agent should be able to penetrate the surface of wooden, maintenance and caulking effect to the template, and can prevent the template for many times after use due to the variation of horn of edge of wood and produce inflation, uplift, cracking and its fault.

Steel with release agent should be to prevent steel corrosion and the resulting concrete surface produce rusty spot.

6, has a good stability

Concrete demoulding agent should have good stability and long storage period.

7, has good water resistance and weatherability

Site construction and use of release agent should have certain of the outdoor rain erosion resistant ability, namely the brush in the release agent on the template after the rain, mold release properties; For hot curing of concrete member, using heat release agent; In cold climates use mold release agent should have frost resistance.
