Double screw extruder generally has two raw material performance molding characteristics, the following we look at these two specific characteristics.

I. Raw material characteristics
What are the raw material characteristics of double screw extruders? Please see I have the following two points to introduce the double screw extruder in detail.

1. Double screw extruder raw material characteristics are specific insulation (especially high-frequency insulation performance) of high quality, milky white hard and brittle, metal material sound falling to the ground, light transmission rate second only to Plexiglas panels, color waterproof, good chemical resistance. With good flame retardant grade material.

2. general compressive strength and stiffness are very good, but the quality of brittle, easy to ground stress brittle crack, is not resistant to benzene. Fuel and other organic solutions. Long-term use of ambient temperature up to 260 degrees, air or 400 degrees of air or N2. in long-term maintenance. According to the modification of glass fiber or other improved materials, impact strength can be significantly increased, temperature resistance and other physical properties are gradually improved, the relative density increases to 1.6-1.9, molding shrinkage is small to 0.15-0.25% suitable for the manufacture of high-temperature resistant parts. Chemical experimental instruments and chemical experimental instruments. Optical equipment and other parts.

II. Forming characteristics
For other natural molding properties, let us look at the molding properties of two characteristics.

1. Indefinite material, moisture absorption is small, but it is desirable to dry after molding.

2. Circulation is in the middle of ABS and PC condensation is fast, closure is small, easy to dissolve, and mold temperature is 100-150 degrees. The main flow channel finish should be large and the overflow channel should be short. Application areas can generally be used in the manufacture of PPS pipes. PPS sheets, etc., are generally used in engineering and construction. Home furniture level.

PS plastic pelletizer basic structure type:1. single screw server 2. water puller head 3. conveyor belt 4. plastic pelletizer.

This generator set is also suitable for.
1. Improvement of modified materials: PP/PA/PBT/ABS/AS/PC/POM/PPS/PET etc. plus glass fiber, and carbon fiber.
2. Blending and gold PCABS/PAABS/CPEABS/PPEPDM/PAEPDM/PPSBS, etc.
3. Adding exchangeability: PE/PP/EVA, etc.
4. Flame retardant masterbatch: PP/PA/ABS/EVA/PBT, etc.
5. Biodegradable masterbatch: PP/PE/PS etc. Tapioca starch, modifier, etc.
