橡胶输送带硫化工艺应该注意什么?

来源:http://www.huafengxiangsu.com 时间:2021-07-30 10:43:04 浏览次数:
1.硫化温度低于143℃时,不建议进行板硫化。
1. Plate vulcanization is not recommended when the vulcanization temperature is lower than 143 ℃.
2.硫化不同规格的带子及可连续硫化的带子时,布层相差不超过2层,宽度相差一般不超过200mm,正硫化时间相差不超过2min,建议按照时间长者进行硫化。
2. When vulcanizing tapes of different specifications and continuously vulcanizable tapes, the difference between cloth layers shall not exceed 2 layers, the difference in width shall not exceed 200mm, and the difference in positive vulcanization time shall not exceed 2min. It is recommended to vulcanize according to the longer time.
3.按批号卡片严格检查带坯宽度、厚度以及外观质量情况,根据压缩比配备垫铁。
3. Strictly check the width, thickness and appearance quality of belt blank according to the batch number card, and equip sizing block according to the compression ratio.
4.橡胶输送带硫化过程中一定要严格控制硫化温度、时间和压力。输送带中掺用再生胶降低成本时,应综合考虑再生胶的加工温度,适当调节硫化参数。

4. Vulcanization temperature, time and pressure must be strictly controlled during vulcanization of rubber conveyor belt. When adding reclaimed rubber to the conveyor belt to reduce the cost, the processing temperature of reclaimed rubber should be comprehensively considered and the vulcanization parameters should be adjusted appropriately.
5.橡胶输送带硫化时如果遇到水门漏水、水压突然下降至规定以下时,只允许硫化完该段输送带,压力不恢复正常不得继续硫化。
5. When vulcanizing the rubber conveyor belt, if the water gate leaks and the water pressure suddenly drops below the specified value, it is only allowed to vulcanize the conveyor belt at this section, and the vulcanization shall not continue until the pressure returns to normal.
6.输送带硫化过程中发生问题必须终断30min以上时,应关闭进汽阀门,并用木杠子将带子垫起,使之全部离开热板。
6. When the conveyor belt has problems during vulcanization and must be broken for more than 30min, the steam inlet valve shall be closed, and the belt shall be padded with a wooden bar to make it all leave the hot plate.
7.硫化出板时开车者必须注视平板内的输送带,如果发现起泡应立即戳穿,开出平板后,再用力将泡剖开,以防气泡膨胀使气泡扩大造成严重损失。
7. When vulcanizing the plate, the driver must look at the conveyor belt in the plate. If bubbles are found, they shall be punctured immediately. After opening the plate, the bubbles shall be cut open with force to prevent bubble expansion and serious loss.
8.在正常情况下,带坯装到平板里,偏装现象不得超过50mm,硫化后的带子两侧厚度偏差不得超过0.5mm。
8. Under normal conditions, when the belt blank is installed in the flat plate, the deviation shall not exceed 50mm, and the thickness deviation on both sides of the vulcanized belt shall not exceed 0.5mm.
9.橡胶输送带硫化时使用硅油、汽油作为隔离剂时,硅油:汽油=1:20(质量比)。
9. When silicone oil and gasoline are used as separators during vulcanization of rubber conveyor belt, silicone oil: gasoline = 1:20 (mass ratio).
10.橡胶输送带硫化接头同规格不必串板,可直接进行硫化。但串带子时不得重复硫化三次。两条不同宽度的带子不能并条硫化。
10. The vulcanization joint of the rubber conveyor belt has the same specification and does not need to be connected with the plate, so it can be vulcanized directly. However, the belt shall not be vulcanized for three times. Two tapes of different widths cannot be vulcanized together.
