Bag filter with a filter on the breaking strength and elongation at break of test conditions

Rate. o3003sO400I5O strength (N) field strength of 32 and pulled down when the cries of the degree of the beauty of building 2. s20s elongation and tensile when the relationship between the degree of left end of the experiment to take 20s as a time, the test results shown in Figure 4. With the tensile elongation rate increases in direct proportion to the increase in basic, it said Chung-Ming La speed changes, the elongation rate is variable. Eg c pour elongation Tsui () Figure 42o. When the growth rate Zhong Zhong Jian degrees amidships and pull between 2.6 and tensile breaking strength of the relationship between degree of left we can see from Figure 5, the tensile breaking strength with the change of speed from the trough-style changes, the speed of the breaking strength can be seen determination is essential. The same sample at different stretching speed, a far cry from the measured values of breaking strength, maximum and minimum difference of as much as 100N. Z Ge Zhen Du 0�� 50200250300 speed (m plus / mln) Figure 5 Zhong Jian breaking strength and pull the United States spent 2.7 degrees and tensile elongation at break of the relationship between the speed shown in Figure 6 shows the fracture rate and pull-Chung Cheung changes extended into the peak-type speed change, said the speed was to determine the fracture Mingla Chung Chung key to growth rate, a direct impact on test results. Nonwovens NOnWOVCnS/tVo1. i3. No. 3Sept. 1999 brick. I} Tridacna gigas North Weaving - Warm squat pan warm letter of Xinjiang group of non-acupuncture, the quality of the online control nonwovens show Qian Fan Ling Lu tame in the production process control, on-line testing the performance of non-woven fabric with a towel in the production process to detect the advantage of defects into cloth. Understanding of process parameters on the performance of non-woven fabric is the basis for identifying and eliminating defects. Non-woven fabric production line to achieve the entire process between the towel and its process automation into the city can be further improved quality and better efficiency. The automation system's main function is to: - on the fiber and the best use of plant resources, to achieve wide-speed operation and low power consumption will urge. To be able to address product quality assurance; - can quickly detect and eliminate the interference factor. Enhance the stability and optimization of the production line production management. Non-woven fabric production line quality monitoring of the overall process automation products, requiring identification of fiber network into a network of processing parameters on the performance of non-woven fabric. In this paper, Li propylene (PP) fiber and high-performance fiber geotextiles acupuncture \The experiment under laboratory conditions, the use of acupuncture machine Dilo needle plate test. Parameters are: the amount of feed,[link widoczny dla zalogowanych], needle density, needle depth and draft value. Changes in these parameters affect the mass per unit area, thickness, strength and permeability characteristics of a stretch. We all know, change is the area with the density changes of acupuncture, acupuncture needle density non-woven fabric will lead to mass per unit area increased. The shrinkage in the area and the increase in quality can be increased to ease the pull Chung. Fiber fineness has little effect on the area of products, so the area is also very small changes in quality. Tong needle-like effect in the acupuncture, the needles change in the shape of the product size is influential. Needles of different shapes of longitudinal changes in particular, but very little horizontal change. At the same time, also affect the choice of needle-fiber network density and per unit area. Because the non-woven fabric with the needle mass per unit area is the increase of the density and fiber network increases with the increase in density, the thickness of the fiber network density increases with the smaller needle. From the 200g / m. The 7dtexPP fiber non-woven fabric of the test needle to draw,[link widoczny dla zalogowanych], fiber network between the thickness and density of acupuncture as a linear function, namely, the thickness of fiber network density decrease with the increase of acupuncture, with the increase in the value of drawing large decrease. ... ..., ... ... ..., ... ... ... ... ..., ..., ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... �� '015. 2 �� 25. 3o0 construction degree (mm, ... Figure 6 and tensile elongation at break in relation to degree 2,8 built under normal circumstances, 20s can guarantee the completion of testing, but not suitable for all test sets. test the length of time and cut not only the size of the sample, more and pull Chung speed and sample materials are directly related. 2.9 sec breaking strength and breaking the determination of growth rate,[link widoczny dla zalogowanych], the premise of the specimen to determine the speed of the test results is the key. breaking strength and elongation at break test results only in a clear tensile Chung speed. it has a practical significance, the test results are only comparable. 3 Conclusion drawing speed not only determines the test time,[link widoczny dla zalogowanych], but decided breaking strength and elongation at break of the determination results. this, pull sad speed should be used as a quantitative value of the test method to be determined. After determining the drawing speed. test of time will naturally be determined. or. breaking strength and elongation of the test results indicate a certain tension in the speed of the breaking strength and elongation at break. In this way, it was more meaningful test results, the results have comparability between. �� Royal
