YYP 121E Air Permeability Tester(cigarette papers,filter plug wrap and filter joiningpaper)
Instrument Introduction:
The permeability tester adopts new technology and is combined with the most common testing method to measure the permeability of paper, cardboard or other sheet-like objects. This instrument is a fully automated device controlled by a single-chip microcomputer. Its testing method meets the requirements of various methods such as Schöberl, Bentsen and Gellray, and is an advanced instrument for testing paper permeability in the papermaking, packaging and cigarette industries in China. Its performance meets international standards.
Working principle:
Based on the principle of the pressure difference method, the pre-treated sample is placed between the upper and lower measurement surfaces. A constant pressure difference is formed on both sides of the sample. Under the action of the pressure difference, the gas flows from the high-pressure side through the sample to the low-pressure side. The permeability of the sample can be calculated based on the area through which the gas flows, the pressure difference, and the flow rate.
Application scope
Paper, cardboard.
Product Function
Test of Air Permeability
Product features
The chips and sensors of this instrument are all imported from the United States. The test results are accurate, repeatable and of high precision.
The design is exquisite: This instrument adopts microcomputer technology and the testing process is fully automated, which is fast and accurate. The results are displayed on a touch screen liquid crystal display, and it also has data recording and processing functions, along with printing output.
The performance is superior: Compared with traditional permeability meters, this instrument has great superiority. For paper with lower permeability, a higher pressure difference can be set, while for paper with higher permeability, a lower pressure difference can be set, making it easy and accurate to measure the results.
It is convenient to use and has high automation: When testing with traditional permeability meters, the process is not only slow but also laborious. In contrast, the testing of this permeability tester is automatic and fast, and the accuracy of the test results is thus guaranteed. Problems such as incorrect operation or low reproducibility of test results, which are caused by poor design and manufacturing technology of the instrument, have been effectively avoided in this instrument.

YY-DH20L Double-planet vacuum defoaming mixer
I. Overview:
YY-DH20L Double-planet Vacuum Defoaming Mixer is an all-round new model that combines the principles and components of traditional dual planetary mixers and high-speed dispersers. It is currently widely used in many fields.
Considering the characteristics of high solid content and high viscosity of power slurry, our company has developed an enhanced power mixer with higher rotation speed and larger torque on the basis of the original planetary power mixer. During the design process, factors such as the rotation speed of the agitator, stirring power, dispersion linear speed, suspension level, liquid flow pattern and the distribution of turbulence intensity in the bucket were fully considered. Its maximum high-speed dispersion linear speed can reach 25m/s, and the enhanced folding blade frame can handle any high-viscosity slurry. The new mixing method – the folding blade frame rotates clockwise in revolution and counterclockwise in rotation, ensuring no dead ends in mixing and no “climbing” phenomenon. In terms of sealing, two sets of mechanical seals plus soft and static seals ensure vacuum degree – theoretically, the sealing performance is enhanced by 30%. The Pt100 temperature sensor is in direct contact with the material, resulting in more accurate measurement and faster response speed, with an error of only ±0.5℃. This machine is composed of a base, beam, column, sealing cover, material cylinder, transmission and electrical control system.
