Detailed introduction

WH (LY-C) Outdoor Thick Steel Structure Fireproof Coating


The outdoor thick steel structure fireproof coating is the first domestic fireproof coating product for outdoor use. Its technical performance is better than the WH type requirements in the GB14907-2002 standard. It has the following characteristics:
People-oriented, green and environmentally friendly, the first fire-resistant coating product in China that has passed China Environmental Labeling Product Certification.
The production time is early, the technology is mature, the technology is advanced, the formula is reasonable, and the weather resistance is excellent.
Excellent fire performance, withstanding the test of the Oriental ethylene construction site fire.
It has a wide range of applications, such as the fire protection of beams and columns of steel frames in railway stations and petrochemical enterprises and the fire insulation of steel pipes, and it is also suitable for the fire treatment of indoor steel structures.

Construction method
(I) Substrate treatment: Before construction, completely remove dust, oil and floating rust on the steel parts to be sprayed, and apply alkali-resistant antirust primer.
(II) Construction method of the ground floor
1. During the construction of I-beam, H-beam and rectangular steel fire-resistant paint with a width of less than 300mm, the fire-resistant paint can be applied after the base material is brushed.
2. In the construction of fire-resistant coatings for I-beams, H-beams, and rectangular steels with a width of more than 300mm, it is necessary to perform screen coating to perform the fire-resistant coating construction. Steel mesh or metal mesh can be selected, and it is fixed by welding steel bars or bonding insulation nails.
Packaging and storage
1. This product powder: Matching glue = 3: 1, in which the packaging is a woven bag lined with plastic bags, each bag is 25kg, and the matching glue is packed in ordinary plastic barrels.
2. The product should be stored in a cool and dry warehouse, and the effective storage period is six months.
3. This product is non-combustible and non-explosive.
