1、要求模具清潔，場(chǎng)地清潔，工具清潔，其次要求車間通風(fēng)，排風(fēng)口應(yīng)設(shè)在下方，送風(fēng)口設(shè)在上方，車間通風(fēng)：夏季溫度≤30℃，冬季溫度≥15℃，濕度≤75%。根據(jù)生產(chǎn)任務(wù)單規(guī)定的規(guī)格，準(zhǔn)備好所需要的模具，準(zhǔn)備工作包括：核對(duì)品種規(guī)格，清潔模具內(nèi)臟及內(nèi)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。用剪刀或切割機(jī)裁剪玻璃布，要適應(yīng)產(chǎn)品要求的鋪放方向：要求正反方向同性的制品，布要縱橫交替鋪放；要求一個(gè)方向機(jī)械強(qiáng)度高的FRP制品，可用單向布裁剪和鋪放。布要留有搭接余量，對(duì)壁厚要求均勻的制品可以對(duì)接，不論搭接或?qū)樱涌p都要錯(cuò)開(kāi)。裁剪時(shí)，布要鋪平，布的大小，形狀由制品尺寸、性能及操作方便酌情處理。

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：對(duì)所有配制的原材料，要有充分認(rèn)識(shí)，明白各自的作用，做到不懂不配，不清楚不配，對(duì)所用容器做到一種顏色一種容器，嚴(yán)禁混合使用。根據(jù)產(chǎn)品的需要，在大的容器中放入樹(shù)脂、色漿、填料等，用機(jī)械攪拌，攪拌時(shí)間由攪拌效果決定。在大料中預(yù)先加入促進(jìn)劑，配小料時(shí)再加固化劑；如果填料布含水量＞1%，必須在1200烘箱中循環(huán)鼓風(fēng)加熱2小時(shí)，冷卻室溫后再用。

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、玻璃鋼糊制：制作膠衣層，要求涂刷均勻。根據(jù)產(chǎn)品性能可用普通樹(shù)脂加入粉末填料來(lái)代替膠衣樹(shù)脂。膠衣層的制作，采用促進(jìn)劑，固化劑的固化體系以增加制品柔韌性。

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.

待膠衣初凝，手感軟而不粘時(shí)，立即鋪層糊制，表層用薄布做表面層。制品厚度決定玻璃布的層數(shù)。增強(qiáng)層采用促進(jìn)劑，固化劑的固化體系，來(lái)增加制品的強(qiáng)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、復(fù)合：把糊制的玻璃鋼鋪層放入模具，用液壓機(jī)壓實(shí)固化，固化時(shí)間的長(zhǎng)短根據(jù)環(huán)境溫度及固化劑的用量而定。

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、切邊：用脫模工具脫模，按規(guī)定尺寸切除毛邊。

5. Trimming: Use a demolding tool to demould and cut off burrs according to the specified size.

6、打孔：把切割的制品放在沖床上，沖連接孔。

6. Punching: Place the cut product on a punch and punch the connecting holes.

7、修整：因脫模造成膠衣剝落部分進(jìn)行修整。

7. Repair: Repair the peeling part of the gel coat caused by demolding.

8、檢驗(yàn)：外觀表面應(yīng)平整、光滑、無(wú)氣泡、無(wú)裂紋、色澤要均勻，部件厚度應(yīng)均勻，邊緣應(yīng)整齊，不得有影響使用的缺陷。

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、包裝入庫(kù)：用草繩（或打包帶）把橋架包扎，入成品庫(kù)。

9. Packaging and storage: Wrap the bridge with straw rope (or packaging tape) and store it in the finished product warehouse.
