Frequently occurring problems on the surface of ABS sheets: White streaks, bubbles, and cloudy watermarks frequently appear on the sheet surface. There are four main causes: 1. Insufficient raw material drying (ABS is highly hygroscopic, with a moisture content > 0.05%) 2. Excessively high barrel/die temperature, leading to thermal decomposition and gas generation from the material 3. Poor venting, insufficient screw back pressure, and air entrapment in the melt 4. Dead corners in the die flow channel, causing melt retention and degradation.

What are the applications of root control meshes? Root control meshes are used in a wide range of applications, from professional nurseries to home use, from common seedlings to rare varieties, and from lowland seedling cultivation to afforestation in saline-alkali land/barren hills. Why are root control meshes used so widely? Roots grow in separate zones without tangling, with good aeration and drainage, allowing for precise control of the seedling growth environment, improving seedling survival rate and uniformity, and making them suitable for large-scale, refined seedling cultivation.
