Injection molding is one of the most widely used methods in plastic processing. This method
applies to all Thermoplastic and parts of the thermosetting polymer, and the number of
finished products is much larger than other conventional metal forming methods. Because
the injection molding proce...
1. Inhibit material degradation
PVC has a large friction heat generation characteristics of materials, materials in the
processing of local overheating and degradation and lead to degradation of materials as
a whole.
2. Modulating resin plasticizing
In plastic thermoplastic processing, the heat...
The lubricant used in plastic processing is to improve the plastic, In particular, the fluidity
and demoulding of the Thermoplastic during processing and forming. The main function of
the lubricant is to reduce the friction between the plastic material and the processing
machinery and the inn...
Color masterbatch can be used for color matching of polyvinyl chloride, polyethylene,
polypropylene, polystyrene and ABS plastics. Its main components are pigments, resins,
dispersants, volume pigments, fluorescent whitening agents, antioxidants, anti-ultraviolet
agents, anti-static agents, to...
At the heart of management is the discovery of humanity and think about what powers can
be activated at the lowest level.
In a mechanical organization, the way to inspire power is simple: fear and greed. If you do
well, you will be given promotions, more power and more bonuses. Is there an addi...
Today Qingdao Sainuo pe wax manufacturers continues to take you to understand the last
part process of PVC pipe abnormal phenomenon causes and solutions.
7. PVC pipe brittle
Cause of occurrence:
(1)Not Enough degree of plasticization;
(2)The screw speed of PVC pipe extruder is too fast;
(3)PVC pi...
Today Qingdao Sainuo pe wax manufacturers continues to take you to understand the second
part process of PVC pipe abnormal phenomenon causes and solutions.
4. There are coke particles or demarcation line in the wall of PVC pipe
Cause of occurrence:
(1)The filter plate is not clean;
(2)Temperatur...
Today Qingdao Sainuo pe wax manufacturers will take you to understand the process of
PVC pipe abnormal phenomenon causes and solutions.
1. There are ripples on the outer surface of PVC pipe
Cause of occurrence:
(1) Uneven overflow around the die of PVC pipe extruder
(2) The temperature of the co...
The main function of polyethylene wax is to reduce the melting point and melt viscosity of
hot melt adhesive, improve the fluidity and wettability of adhesive, increase the adhesive
strength, prevent the hot melt adhesive from caking and reduce the cost. Most hot melts are
to add a certain amo...
There are unavoidably some unexpected situations in industrial production. For example, in
the processing of PVC products in the common accident is a sudden power failure or because
of some unexpected situation caused the sudden stop of the machine. Sudden downtime is
more to test the static s...
Why is it always difficult for us to start doing things well and do well at the end? There are
two kinds of situations: a lack of motivation and a lack of execution.
A lack of motivation is usually a lack of purpose, a belief that nothing is important. The
latter is when you know what you want,...
Last article we learned the first two methods to solve the color masterbatch after use fade, today Qingdao Sainuo
polyethylene wax manufacturer continue to take you to understand the remaining two solutions.
1. Oxidation resistance
After oxidation, some organic pigments degrade or change their c...
Color masterbatch is because of its own performance characteristics can stand out in a large number of dyes, when
it is used not only the color can not fall long, but also very environmentally safe. But some people have reflected
that, why buy the color masterbatch after the use of a short peri...
In the formulation of non-plasticized PVC pipe, the addition of lubricant not only affects the process conditions, but
also directly affects the strength of the pipe. If too much lubricant is added, the discharging speed will be reduced
and the normal operation will be disrupted. The correct cho...
