ASTM G154 UV Lamp Environment Test Machine Program Controllable

Main feature:

Aging:this machine is to promote the deterioration of vulcanite, and then to calculate the change rate of tensile and elongation. But also the role of ultraviolet radiation to simulate sun and heat, the specimen in the machine in the desks by ultraviolet radiation and temperature effects, over time, observed the extent of the sample resistance to yellowing, discoloration of gray scale can be used as a reference, to determine its yellowing level.Product in the course of radiation or by sunlight during transport, the impact of the container environment change in color caused by the occurrence of the defective product in this machine using the UV lamp 300W, so that experiments can be completed in a shorter time, this machine can be used as the basicresistance to yellowing test, also when the aging test machine and oven use, showing a multi-function machine This machine is equipped with forced hot air circulation control system to ensure uniform temperature distribution.

Working principle

When the internal mixer works, the two rotors rotate relative to each other to clamp the materials from the feeding port into the roll gap, which is squeezed and sheared by the rotor. After passing through the roll gap, the sharp edge of the lower top bolt is divided into two parts, which return to the top of the roll gap along the gap between the front and rear chamber walls and the rotor respectively. During the cycle around the rotor, the material is subjected to shear and friction everywhere, which makes the temperature of the rubber rise sharply, reduces the viscosity, increases the wettability of the rubber on the surface of the compounding agent, and makes the rubber fully contact with the surface of the compounding agent. The compounding agent mass passes through the gap between the rotor and the rotor, the gap between the rotor and the upper and lower top bolts and the inner wall of the internal mixing chamber together with the rubber, is sheared and broken, surrounded by tensile deformed rubber, and is stable in the broken state. At the same time, the convex edges on the rotor make the rubber move along the axial direction of the rotor, play the role of stirring and mixing, and make the compounding agent mix evenly in the rubber. The compounding agent is repeatedly sheared and broken, the rubber material is repeatedly deformed and restored, and the rotor convex edge is continuously stirred to make the compounding agent disperse evenly in the rubber material and reach a certain degree of dispersion. Because the shearing effect of rubber material during mixing by internal mixer is much greater than that of open mixer and the mixing temperature is high, the mixing efficiency of internal mixer is much higher than that of open mixer.
