建筑網(wǎng)的長度對焊點(diǎn)的影響。 在位移測試曲線上,涂層與篩子之間的剝離力不同:增加了網(wǎng)格距離,即樣品變長了。 分離過程變得越來越模糊,并且在曲線上的重要性越來越小。
The influence of the length of building net on the solder joint. On the displacement test curve, the peeling force between the coating and the sieve is different: the grid distance is increased, that is, the sample becomes longer. The separation process becomes more and more blurred and less important on the curve.
但是,從該曲線可知,隨著網(wǎng)眼間距的增加,測得的實(shí)驗(yàn)力值越來越大,但鍍鋅層與網(wǎng)眼之間的拉力仍為100N左右,變化不大, 目距較小樣品鍍鋅層的剝離力非常明顯,可以簡單觀察到。
However, with the increase of mesh spacing, the measured experimental force increases, but the tension between the galvanized layer and the mesh is still about 100N, which has little change. The peeling force of the galvanized layer of the sample with smaller mesh spacing is very obvious and can be easily observed.
可以看出,隨著網(wǎng)孔距離的增加,焊點(diǎn)的抗拉強(qiáng)度也逐漸增加。 8倍網(wǎng)格距離大于以1毫米/分鐘表示的4倍網(wǎng)格距離的采樣距離。 52N時(shí),力值以1mm / min大于5倍網(wǎng)眼距離樣品的18N,這表明樣品越長,形成的焊點(diǎn)抗拉強(qiáng)度的正值就越大,規(guī)范的規(guī)則是 盡可能選擇。 長度,這是在檢查工作中應(yīng)注意的問題。
It can be seen that with the increase of mesh distance, the tensile strength of the solder joint increases gradually. 8 times the grid distance is greater than the sampling distance of 4 times the grid distance expressed in 1 mm/min. At 52N, the force value is greater than 18N of the sample with a mesh distance of 1 mm/min greater than 5 times. This indicates that the longer the sample is, the greater the positive value of the tensile strength of the solder joints formed. The rule of the specification is to select as much as possible. Length, which should be paid attention to in the inspection work.
鍍鋅層焊點(diǎn)的抗拉強(qiáng)度值在曲線上反映為較大的實(shí)驗(yàn)力值。 該值是在工程驗(yàn)收測試中測得的焊點(diǎn)拉伸值; 鍍鋅層的剝離力在曲線上很顯著。 力值在90到100N之間; (3對“ J”型夾具可用于鍍鋅電焊網(wǎng)在電子測試機(jī)上的固定問題,對于避免損壞焊點(diǎn)非常有用。
The tensile strength of galvanized solder joints is reflected as a larger experimental force on the curve. This value is the tensile value of solder joints measured in engineering acceptance test, and the peeling force of galvanized coating is remarkable on the curve. The force value is between 90 and 100N; (3 pairs of "J" fixtures can be used to solve the fixing problem of galvanized welding net on electronic testing machine, which is very useful for avoiding damage to solder joints.
該建筑網(wǎng)具有保溫,隔音,抗震,防水,施工簡單,重量輕等特點(diǎn),擴(kuò)大了建筑的使用范圍,大大降低了工程造價(jià)。 施工網(wǎng)的長度一般尺度為:1m * 2m2m * 4m大于6m,否則不好生產(chǎn)。
The building network has the characteristics of heat preservation, sound insulation, seismic resistance, waterproof, simple construction and light weight, which enlarges the use scope of the building and greatly reduces the cost of the project. The length of construction network is generally 1 m * 2 m * 4 m larger than 6 m, otherwise it is not good for production.
