Background technology
Plastic extruder filter screen is one of indispensable process equipment of manufacture of polyolefins industry, its major function is
Filtering is in impurity in molten condition polyolefin medium, such as metal fragment.
China's materials industry has been enter into the maturity period after the fast-growing period by the more than ten years, and industry, which will enter, integrates rank
Section, and composite industry has just enter into the growth stage, the following industry entirety level of profitability will show the situation persistently risen steadily.
At the same time, it is also higher and higher to the requirement of product.For example the requirement to product cleanliness factor is also higher and higher, it is especially several recently
Year, more and more clients are almost harsh to product purity requirements, and most typical is exactly the control to product stain.Specific to
Using, such as the extremely requirement of white domestic appliances, LED lamp cover, fascia is zero stain, no pollution unexpectedly, such as 50CM X
There cannot be one 50 μm of pore on the pure white panel of 100CM.Popular says, cannot exactly have on the panel of above-mentioned area
The stain that naked eyes can see.If pure transparent material, such as acrylic, makrolon (PC) etc., it is desirable that it is just harsher,
Because product is entirely transparent, entire moulding cannot be there are one stain.If there are one stains, it is more prone to pass through instead
It reflects and is found, this is proposed very high requirement to blending and modifying producer and injection molding manufacturing enterprise.
For the control of stain, everybody is first it is contemplated that control environment, followed by feed product, finally
It is production technology.But only accomplish that these are also far from enough.Because even production environment is good again or even in dust-free workshop, original
Material material is actually not achieved, production process controls good again, cannot guarantee that final products stain reaches at all close to zero stain
To requirement.Because plastics are in blending heating process inside extruder, due to the heat and screw rod shearing of external barrel, material exists
During fusion plastification, with the accumulation of time, can inevitably cause the fracture or even degradation of molecule segment, generate stain or
Large area darkens obfuscation.
For such case, Current Domestic common practices is, in extruder at mouth mold, adds one layer of filter screen, due to
Strainer is too close, it is easy to block, it is excessively frequent to change strainer.Both the labor intensity of worker had been increased, has also increased production cost.Filter
