What are the main applications of PU foaming machine: 

1. Flat roof waterproof and thermal insulation. 

2. Wall heat preservation. 

PU foaming machine can be used as wall insulation has more advantages. 

Assembled large wallboard, sprayed between the plate ribs, bonded well and tightly. 

At present, the key to wall reform is thermal insulation technology, foamed polyurethane can make great progress. 

If the hollow block is used, the foamed polyurethane of the PU foaming machine can be sprayed in the hole and filled with full plug. 

The walls of the freezer are best sprayed.

3. The exterior wall of the basement is insulated and waterproof. 

Basement exterior wall insulation and waterproofing, foamed polyurethane is the best part, not only heat preservation, waterproof, but also save other protective layers, two at one go. 

4. Tile roof. 

The foamed polyurethane of the PU foaming machine is sprayed on the lower edge of the watchboard, and the tile base slurry is on the watchboard without sliding. 

PU foaming machine is a convenient operation, smooth appearance lines, soft color products, can replace the old foaming machine, and easy to maintain. 

Introduction to white and black materials of pu foaming machine: 

The PU foaming machine can make foam, but how does it make the foam? the foaming machine itself cannot produce foam out of thin air. It introduces air into the aqueous solution of the foaming agent and disperses it evenly. 

The contact surface of liquid and gas is as large as possible so that the surface active matter in the foaming agent forms a double electric layer on the surface of the liquid film and surrounds the air to form bubbles. 

What are the white and black materials of the pu foaming machine? 

Black material, also known as B material, is MDI or TDI class. 

White material, also known as A material, is polyester or polyether, said (black color is white), should be pure MDI. 

(the white color is black), it should be polyester or polyether combination with black paste. 

The suggestion is still called A material, B material!
