Identify the quality problems of plaster bead

1. The market price of the worst plaster bead is usually around 1.00 yuan to 1.60 yuan. Its Profile Pvc is usually made of waste glass from beer bottles. The production process is clay crucible drawing, which is a production process prohibited by the state, and the surface coating is not alkali-resistant emulsion.

From an intuitive point of view: the workmanship is relatively rough, and it is generally sold in rolls in the market. It is often insufficient in length and weight, and it breaks after two folds. The joints are not firm and easy to shift, and it is easy to pierce the skin. This type of plaster bead used in the insulation layer generally loses its strength after two months. If the mortar is knocked off and the plaster bead is taken out, the Profile pvc yarn will become powder with a light grind.

2. There is also a kind of imitation platinum plaster bead, also called mixed silk yarn. This is a better imitation of Profile pvc, but the waste glass it chooses is usually some flat broken glass with good transparency, and the fiber diameter is relatively thin. It is sometimes difficult to judge its authenticity from the surface, but its quality does not meet the requirements of real Profile pvc in external wall insulation in any case.

3. Standard Profile pvc with good quality are all made of Profile pvc as the base material, and the selection of materials and the weaving process are very particular. The coating emulsions used have good alkali resistance. The excellent alkali resistance and high tensile strength in the warp and weft directions make the product feel good and have good construction compliance, which greatly reduces the amount of plastering mortar.
