The laboratory adhesive kneading machine is composed of a pair of blades (usually Z-shaped) that cooperate and rotate with each other to produce strong shear action, allowing semi dry or rubber like viscous plastic materials to react quickly and achieve uniform mixing and stirring.

SPECIFICATION
This is a 2L standard Sigma Mixer, it has 0.5-1.5L batch work volume. Discharged by screw extrusion, based on electrical heater heating in the meanwhile.

Hot melt adhesive kneading machine: Hot melt adhesive, also known as hot melt sealant, is the most advanced high torque kneading machine specially designed for hot melt sealant. It can knead adhesive slurry with viscosity ranging from several hundred thousand to one million poise, heating temperature at 170 ℃, and vacuum degree up to 0.095Mpa. The hot melt adhesive kneading machine not only has the function of screw extrusion discharge, but also solves the problem of raw material storage in the screw feeding port of traditional kneading machines. The hot melt adhesive kneading machine can replace the old production process (combination of open type rubber mixing machine and open type hot mix machine), and the adhesive produced by this kneading machine has excellent effects on air glass butyl hot melt adhesive, automotive sealing, building sealing tape, etc.: 1. Good molding, 2. Bright and beautiful appearance, 3. Eliminating bubbles in the adhesive. The hot melt adhesive kneading machine is an indispensable production tool for manufacturers of butyl hot melt adhesive and butyl tape.

Silicone rubber special kneading machine: This machine is suitable for silicone rubber enterprises to mix, shear, and extrude ultra-high viscosity materials in a vacuum state, making the rubber and filling materials knead and disperse faster, reducing production time and energy consumption, and playing an important role in improving the storage stability of finished rubber and increasing product strength.
Silicone sealant special kneading machine: mainly suitable for high viscosity silicone sealant. Silicone sealant is a type of building sealing material that can withstand the outward movement of joints to achieve airtightness and water tightness, and is embedded in building joints. After the elastic sealant is embedded in the joint, it shows obvious elasticity. When the joint moves outward, the residual stress caused in the sealant is almost proportional to the strain.
