1、要求模具清洁,场地清洁,工具清洁,其次要求车间通风,排风口应设在下方,送风口设在上方,车间通风:夏季温度≤30℃,冬季温度≥15℃,湿度≤75%。根据生产任务单规定的规格,准备好所需要的模具,准备工作包括:核对品种规格,清洁模具内脏及内模外表面。
1. Firstly, mold cleaning, site cleaning, and tool cleaning are required. Secondly, workshop ventilation is required, with exhaust outlets located below and supply outlets located above. Workshop ventilation: temperature ≤ 30 ℃ in summer, ≥ 15 ℃ in winter, and humidity ≤ 75%. Prepare the required molds according to the specifications specified in the production task order. The preparation work includes checking the variety specifications, cleaning the internal and external surfaces of the molds.
裁布:要求玻璃布不要受潮,不受污染。用剪刀或切割机裁剪玻璃布,要适应产品要求的铺放方向:要求正反方向同性的制品,布要纵横交替铺放;要求一个方向机械强度高的FRP制品,可用单向布裁剪和铺放。布要留有搭接余量,对壁厚要求均匀的制品可以对接,不论搭接或对接,接缝都要错开。裁剪时,布要铺平,布的大小,形状由制品尺寸、性能及操作方便酌情处理。
Cloth cutting: It is required that the glass cloth should not be damp or contaminated. Using scissors or cutting machines to cut glass cloth, it is necessary to adapt to the laying direction required by the product: products that require the same direction in both directions should be laid alternately vertically and horizontally; FRP products with high mechanical strength in one direction can be cut and laid with unidirectional cloth. The fabric should have overlap allowance, and products with uniform wall thickness requirements can be connected. Whether overlapping or connecting, the joints should be staggered. When cutting, the fabric should be laid flat, and the size and shape of the fabric should be handled according to the size, performance, and ease of operation of the product.
2、配料:对所有配制的原材料,要有充分认识,明白各自的作用,做到不懂不配,不清楚不配,对所用容器做到一种颜色一种容器,严禁混合使用。根据产品的需要,在大的容器中放入树脂、色浆、填料等,用机械搅拌,搅拌时间由搅拌效果决定。在大料中预先加入促进剂,配小料时再加固化剂;如果填料布含水量>1%,必须在1200烘箱中循环鼓风加热2小时,冷却室温后再用。
2. Ingredients: All prepared raw materials should have a full understanding and understand their respective roles, and be clear about whether they are compatible or not. The containers used should be of one color and one type, and mixing is strictly prohibited. According to the needs of the product, place resin, color paste, fillers, etc. in a large container and stir mechanically. The stirring time is determined by the stirring effect. Add accelerator in advance to the large material, and then add curing agent when preparing small materials; If the moisture content of the filler cloth is greater than 1%, it must be heated by circulating air in a 1200 oven for 2 hours, cooled to room temperature, and then reused.
3、玻璃钢糊制:制作胶衣层,要求涂刷均匀。根据产品性能可用普通树脂加入粉末填料来代替胶衣树脂。胶衣层的制作,采用促进剂,固化剂的固化体系以增加制品柔韧性。
3. Glass fiber reinforced plastic pasting: First, make a gel coating layer, which requires uniform brushing. According to product performance, ordinary resin can be added with powder fillers to replace gel coat resin. The production of the gel coat layer adopts a curing system of accelerators and curing agents to increase the flexibility of the product.
待胶衣初凝,手感软而不粘时,立即铺层糊制,表层用薄布做表面层。制品厚度决定玻璃布的层数。增强层采用促进剂,固化剂的固化体系,来增加制品的强度。

When the gel coat is initially set and feels softbut not sticky, immediately lay a layer of paste and use a thin cloth as the surface layer. The thickness of the product determines the number of layers of glass cloth. The reinforcing layer adopts a curing system of accelerator and curing agent to increase the strength of the product.
4、复合:把糊制的玻璃钢铺层放入模具,用液压机压实固化,固化时间的长短根据环境温度及固化剂的用量而定。
4. Composite: Place the pasted fiberglass layer into the mold, compact and solidify it with a hydraulic press, and the curing time is determined by the environmental temperature and the amount of curing agent used.
5、切边:用脱模工具脱模,按规定尺寸切除毛边。
5. Trimming: Use a demolding tool to demould and cut off burrs according to the specified size.
6、打孔:把切割的制品放在冲床上,冲连接孔。
6. Punching: Place the cut product on a punch and punch the connecting holes.
7、修整:因脱模造成胶衣剥落部分进行修整。
7. Repair: Repair the peeling part of the gel coat caused by demolding.
8、检验:外观表面应平整、光滑、无气泡、无裂纹、色泽要均匀,部件厚度应均匀,边缘应整齐,不得有影响使用的缺陷。
8. Inspection: The appearance surface should be flat, smooth, without bubbles, cracks, and uniform in color. The thickness of the components should be uniform, and the edges should be neat without any defects that may affect their use.
9、包装入库:用草绳(或打包带)把桥架包扎,入成品库。
9. Packaging and storage: Wrap the bridge with straw rope (or packaging tape) and store it in the finished product warehouse.
