Melt pumps come in a variety of types and sizes to fit the needs of your polymer production process.
Benifits of the metering pump melt gear pump
1. Stabilizing the output pressure---the pressure on extruder can be reduced by 30%-50% after using melt pumps.
2. improving the product quality
3. increasing the extrusion output---reducing pressure on screw and chaning the building pressure from "screw to die" to "melt pump to die", so the screw can extrude the products with high efficiency. Mean while the back-pressure on the extruder can be adjusted, reducing the melt residence in screw cylinder, stabilizing the plasticizing process and improving the product's quality and quantity.
4. prolonging the working life---the pressure of extruder screw can be lowered after using the melt pumps, so screw wear can be reduced consumable

GL steel coil is an important alloy material often used in daily life. The galvalume steel coil is composed of aluminum-zinc alloy structure, which is composed of 55% aluminum, 43% zinc and 2% silicon solidified at a high temperature of 600℃. The entire structure is composed of aluminum-iron-silicon-zinc, forming a dense four-element An alloy of crystals.
Characteristics: Aluminium galvanized steel coil has many excellent characteristics: strong corrosion resistance, 3 times that of pure Galvanized Coil; beautiful spangles on the surface, which can be used as building exterior panels.
1. Corrosion resistance:
The corrosion resistance of "aluminized zinc steel coil" is mainly due to the protective function of aluminum and aluminum. When zinc is worn, aluminum forms a dense layer of aluminum oxide, which prevents corrosion-resistant substances from further corroding the interior.
2. Heat resistance:
aluminum-zinc alloy steel coil has good heat resistance and can withstand high temperatures of more than 300 degrees Celsius. It is similar to the high temperature oxidation resistance of aluminum-plated steel sheets. It is often used in chimney pipes, ovens, luminaires and fluorescent lampshades.
3. Heat reflectivity:
The heat reflectivity of Galvanized Steel Coil is very high, which is twice that of galvanized steel. People often use it as a material for heat insulation.
4. Economy:
Because the density of 55%AL-Zn is lower than that of Zn, the area of galvanized steel coil is more than 3% larger than that of coated steel coil with the same weight and the same thickness of gold plating.
use
Construction: roofs, walls, garages, soundproof walls, pipes and modular houses, etc. Automobiles: mufflers, exhaust pipes, wiper accessories, fuel tanks, truck boxes and other home appliances: refrigerator back panels, gas stoves, air conditioners, electronic microwave ovens, LCDs Frames, CRT explosion-proof belts, LED backlights, electrical cabinets and other agricultural applications: pig houses, chicken houses, granaries, greenhouse pipes, etc. Others: thermal insulation covers, heat exchangers, dryers, water heaters, etc.
Precautions for use
Storage: It should be kept indoors such as warehouses, kept dry and ventilated, and do not store it in acidic climates for a long time. When storing outdoors, it is necessary to prevent rain, and avoid condensation caused by oxidation stains. Transportation: To avoid external impact, SKID must be used to support steel coils on transportation tools to reduce stacking and take rain-proof measures. Processing: The same lubricating oil as the aluminum plate is required for the cutting process of COILCENTER. When drilling or cutting galvanized steel sheets, the scattered iron filings must be removed in time.
