Get together the construction of Niao waterproof coating explains
From;    Author:Stand originally

  Construction explains:

1, base material processing: Concrete base material is before finishing, should achieve exterior level (face of counterpoise important place should accomplish flatness to not be more than 2mm/m) . New concrete base material should sufficient conserve (time 28 days of above) , accomplish complete solidify, reach the quality target that project place needs. Base material should sufficient and dry, moisture content is under 8 % . PH is worth < 10.

To steely surface, requirement gush is arenaceous the Sa2.5 level that should reach GB/T8923 to set except rust. Be like condition of be confined to, also can divide rust by hand, but must reach St3 level.

2, can use priming paint of form a complete set according to specific requirement (it is polyurethane normally kind or epoxy resin kind) , the spray that undertakes base material priming paint, roller besmears or brush besmear, with assuring to get together Niao coating is mixed the adherent force of base material.

3, spray gets together when Niao coating works, should use double constituent high pressure, high temperature, bump without gas inside mix, machinery undertakes spray construction from rinsing equipment. Craft pressure is 2000psi (14.0MPa) ~ 2500psi (17.3MPa) , craft temperature is 60 ~ when 70 ℃ , can come true sufficient pulverization and mix, obtain high grade coating.

   Pack:

A constituent 240kg/ bucket; R constituent 200kg/ bucket

  Keep in storage:

As a result of the lively sex of A constituent, generate extremely easily with water reaction not dissolve sex Niao, make viscosity elevatory, emit carbon dioxide, cause bosomy bucket, because this keep in storage is medium,must prevent what water divides enter. After unsealing, apply dry nitrogen protection, store temperature is 10 ~ 30 ℃ . R constituent is suck wet sex colophony extremely easily, dry nitrogen protection is used after opening a bucket. 0 ℃ are the following, a group branch has crystallization separate out, answer to heat to be used later quickly in 70 ℃ . In keep in storage forbidden drench, insolate.

Below appropriate reserve requirement, period of efficacy is a year.

   Note:

A few vapour are contained to volatilize in use process, the attention discharges wind.

Absorb vapour excessive to be able to cause respiratory tract allergy to react, should apparel of a complete set of defend appliance (if defend,take, glove, defend lens) undertake construction is operated.

Once splash an eye, rinse with clear water of going from place to place instantly, at least 15 minutes.

After the skin is contacted, take off the dress that is polluted, rinse the skin with a large number of water.

Absorb vapour excessive to be able to cause respiratory tract allergy to react, should apparel of a complete set of defend appliance (if defend,take, glove, defend lens) undertake construction is operated.
