玻璃钢喷淋管道手糊成型工艺是一种简单成熟的成型工艺，其典型工艺过程是：在涂有脱模剂的模具上，将加有固化剂的树脂混合料和玻璃纤维织物手工逐层铺放，浸胶并排除气泡，层合至确定厚度，然后固化形成制件。

Hand lay up molding glass steel pipe spray process is a simple and mature process, the typical process is: in the mould coated with release agent, add curing agent resin mixture and glass fiber fabric hand layer placement, dipping and remove air bubbles, to determine the thickness of laminated. And then cured to form parts.

手糊成型技术的优点是：无需专用设备，投资少；不受制品形状和尺寸的限制，特别适于数量少、整体式及结构复杂的大型制品的制作；可以根据设计要求合理利用增强材料，能随意局部增强，做到以最低成本实现设计要求，而且当设计不合理时能方便地进行修改；操作方便，容易掌握，便于推广。

The advantages of hand lay up molding technology are: no need of special equipment, low investment; from the product shape and size, making products, especially suitable for a large number of small and complex integral structure; can make reasonable use of reinforced materials according to the design requirements, can achieve local enhancement, at the lowest cost to achieve the design requirements, and when the unreasonable design can easily be modified; easy to operate, easy to master, easy to popularize.

手糊工艺的缺点是：制品质量不易控制，人为因素大；制品的强度和尺寸精度较低；劳动条件差，生产效率低。

The disadvantages of hand finishing are: the quality of the product is not easy to control, the human factor is large; the strength and size accuracy of the product is low; the working condition is poor; the production efficiency is low.

玻璃钢喷淋管道喷射成型工艺是手糊成型的改进，属于半机械化成型工艺。它是将混有引发剂和促进剂的两种聚酯树脂分别从喷枪两侧喷出，同时将切断的玻纤粗纱由喷枪中心喷出，使其与树脂均匀混合，沉积到模具上;当沉积到一定厚度时，用辊轮压实，使纤维浸透树脂，排除气泡，固化后成制品。

The spray forming process of glass fiber reinforced plastic spray pipe is improved by hand molding, which belongs to the semi mechanized forming process. It is mixed with two kinds of polyester resin, initiator and accelerator respectively from both sides of the spray gun, the gun by fiberglass roving cut off center jet, which is uniformly mixed with the resin deposition to the mold; when the deposition to a certain thickness, by roller compaction, the fiber impregnated resin, remove air bubbles, into the cured products.

喷射成型的优点是：用玻纤粗纱代替织物，可降低材料成本；生产效率比手糊的高2～4倍；产品整体性好，无接缝，层间剪切强度高，树脂含量高，耐腐蚀、耐渗漏性好；产品尺寸、形状不受限制。

Injection molding has the advantages: instead of fabric with fiberglass roving, the material cost can be reduced; the production efficiency is 2 higher than the hand to 4 times; the product is good, no seams, interlaminar shear strength, high resin content, corrosion resistance, leakage of good products; size and shape are not limited.

喷射成型的缺点是：树脂含量高，制品强度低；产品只能做到单面光滑；污染环境，有害工人健康。

The disadvantages of spray forming are: high resin content and low strength of products; products can only be smooth on one side; pollute the environment and harm the health of workers.
