How to identify Profile Pvc with quality problems

① From an intuitive point of view: the workmanship is relatively rough, and it is generally sold in rolls in the market. It is often not long enough, not heavy enough, and breaks after two folds. The joints are not firm and easy to shift, and it is easy to pierce the skin. This type of Profile Pvc used in the insulation layer generally loses its strength after two months. If the mortar is knocked off and the Profile Pvc is taken out, the Wall Corner yarn will become powder with just a slight grind.

② There is also a kind of Profile Pvc, also called mixed silk yarn. This is a better imitation of Wall Corner, but the waste glass 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 exterior wall insulation.
③ Standard Profile Pvc with good quality uses platinum Wall Corner as the base material, and is more particular about the selection of materials and the weaving process. The coating emulsion used has good alkali resistance. Excellent alkali resistance and high tensile strength in warp and weft directions make the product feel good and have good construction compliance, which can greatly reduce the amount of plastering mortar.
