织物芯输送带硫化连接法
一.作业现场要求(site require)
1.要选择水分、粉尘较少的场所(NO Water and less dust)
2.大雨天在室外不能胶接（特殊情况除外）小雨应当搭建雨棚(Not allowed in big rain, canopy can be built in rain day )
二.胶接前两个检查(the check before work)
1.检查胶浆胶料型号是否对是否在保质期内(check the type of sizing material and its guarantee period)
2.检查硫化机设备是否完好，有无故障(check the status of vulcanizing machine)
三.作业工具(tools)
1.硫化机一套(one vulcanizing machine)
利大于弊
2.角向砂轮、电吹风、卷尺、弹线器、刀、螺丝刀、剪刀、胡桃钳、记号笔、剥头机（没有的可人工剥）、三箱单箱接线盒、水源(grinding wheel, electric hair drier, tape, snapline, knife, screwdriver, scissors, cracker, marking pen)
3.消耗材料consumable material
长睫毛的小窍门
钢丝砂轮片、刷子、清洗剂（汽油或甲苯）、胶料、胶浆。将胶带与加热板隔离的材料。(grinding wheel, brush, cleaning agent(gasoline or methylbenzene), sizing material, adhesive)
四.接头joint
青鸟读后感1.将准备工作做好，开始架硫化机(make ready, t up vulcanizing machine)
架硫化机时，先放好工字钢，再放水压板、下加热板、注意加热板要与支架平行
(firstly, put i-bar. Then put water pressure plate and heating plate. Heating plate should parallel with support)
2.确定接头的长度、角度、中心线、方向(make sure the length, angle, centre line, direction )
a.接头长度 ：标准L=（n-1）s+50单位：mm (length of joint : L=（n-1）s+50mm)
茉莉花开花时间L:接头长度length of joint n：带芯的层数(number of plies) 50：封口胶宽度width of aling compound s：搭接长度splicing length
如下表：

一般情况下接头长度为650mm时就能满足强度要求，所以如没有特殊要求，通常都把接头
长度定为650mm 左右。(Generally, length of joint L is 650mm. it meets the strength requirement. So if there is no special requirement, the length of Joint is 650mm)
b.角度、中心线方向(angle and centre line, direction )
接头时如没有特殊要求一定要接斜头，因为胶带在运转时要经过各种辊筒会产生曲挠力，如胶接为平头胶接，那么运转过程中，所有力会直接作用在输送带的胶接部位的平头处，的端线处，受力面面积狭窄，将会造成过早疲劳或断裂，而斜接头则将所有力分散在点上，受力面面积相对大，能相对延长接头寿命。所以要采取斜接头方式。（斜度为西方历史时间轴72.5°或为带宽的0.35倍）详见下图1
If there is no special requirement, the joint should be sideling in one angle. This can increa the force area in joint and extend the life of joint. (the angle is 72.5° or 0.35 times of belt width). Plea e Figure 1

运行方向(moving direction of belt)
上封口处(top al )
下封口处(bottom al)
接头方向要与运行方向一致，运行方的那个头剥非工作面，另一个头剥工作面
The direction of splice is same with moving direction. peel non-working surface in the head of moving direction. Peel working surface in another head.
3. 剥头peel head
剥头前先把工作面的封口胶剥掉，宽度(2-5)cm，开刀时，覆盖胶应切成45°斜坡，剥布层时要一层一层地剥；开刀时一次只能开一层布，不能伤到下层布，剥离第一层布时可以连覆盖胶一起剥掉，需剥掉的带芯的层数为带芯总层数-1层。
Peel off the aling rubber on working surface. The width is 2-5cm. Cover rubber should
be cut in 45° slope. Peel off one layer of cloth in one time. And don’t hurt the next layer of cloth. Peel off the cover rubber when peel the first layer of cloth. The number of layers, need to cut off, is the number of layers minus one.
注意：剥头时所剥的两个头，运行方向的那个头剥非工作面，另一个头剥工作面。所剥布层之间的距离要相等（布层之间的距离l=接头长度/n-1 n为布层数）
Note: In two head, peel non-working surface in the head of moving direction. Peel working surface in another head. The distance among the layer of cloth is same. (the distance = L length of joint/n-1 n:the number of cloth.)
4.打磨、清洗Polish and clean
剥好头后，要对所剥掉的地方和封口处打磨平整，但不要将覆盖胶打焦，也不要将带芯打磨的发白，不要损伤带芯，打磨好后用吹风机刷子清理杂物，并用清洗剂对打磨的部位进行清洗。
After peel off, polish all peeled and aling areas. Do not remove the cover rubber and do
not polish and whiten the belt core. Do not damage the core. After polishing, clean up with blower brush and detergent.
5.涂胶浆、铺芯胶、封口胶Apply mucilage, core glue and aling glue
清洗烘干后，先在接头的四边涂胶浆，（注意胶浆只能涂在胶上，不能涂在布上）然后再开始涂胶浆，胶浆要涂均匀一遍涂第二遍，待第二遍铺芯胶，芯胶要铺到位，特别是靠近两边边胶处要多放3-4层芯胶，否则硫化好的带体边部容易有海绵。芯胶铺好后按照中心线把两个头合上，先在封口处贴上芯胶然后再用封口胶将上下封口处填满，为了便于拆卸工作面、非工作面在输送带与上下加热板之间放上隔离材料。（如无纺布、报纸、耐热熟料薄膜等）
After drying, apply core glue on the joint, (core glue can only be applied on the glue but not on cloth) and then apply mucilage evenly. Second applying shall be done after it gets dry for the first time. Apply core glue after it gets dry for the cond time. Core glue shall be applied 3 to 4 layers on the two edge sides. Otherwi, the belt edge is easily sponged. Clo the joint according to the center line, apply core glue on the al and fill s
ealing glue. For the convenience of dismantling work platform, put insulation material (e.g., non-woven fabric, paper, refractory clinker film, etc.) between belt and heating plates.
五.加压硫
硫化vulcanization：
我公司输送带硫化温度如下temperature should control as following：
1) EP、NN：140-145℃
耐高温日本化妆品High temperature resistant：150-155℃
2) 硫化时间vulcanization time：
硫化计时从硫化平板温度升到硫化温度时开始计时。
