Description

Wet method burning into sand system and the manufacturing process of continuous winding production line
Technical field
The present invention relates to fiberglass reinforced plastics sand-inclusion pipeline wrapping machine technical field, particularly be applied to make under the continuous winding process condition fiberglass reinforced plastics wet method sand-inclusion pipeline system and manufacturing process.
Background technology
Produce the fiberglass reinforced plastics sand-inclusion pipeline at present in the world, mainly contain three kinds of moulding process: fixed length winding process, continuous winding process and spun casting technology:
1) the fixed length winding process is on the certain pipe die of length, adopts spiral winding and/or hoop winding process successively to make a kind of production method of tubing from the inside to the outside in pipe die length.
2) spun casting technology is with feeding machine glass fibre, resin, quartz sand etc. to be cast in the mould that is rotating by certain requirement, solidifies a kind of production method that the back forms tubing.
3) winding process is on the mould of output continuously continuously, adopts resin, continuous fiber, chopped strand and quartz sand the hoop winding method to spread layer continuously by certain requirement, and cuts into a kind of production method of the pipe material product of an irregular length after solidifying.
Dominate is that fixed length winding method is produced GRP pipe in the present domestic market, and its main feature is that cost of investment is low, and turnover is fast, but exists the drawback that automaticity is not high, production efficiency is low, ambient influnence is big simultaneously.
Continuously winding production line has automaticity height, steady quality, overall merit that environmental impact factor is little, but exists cost of investment height, the high characteristics of product cost simultaneously.
The producer that produces at present continuous winding production line in the world mainly contains Saudi Arabia AMIANTITTE company and Italian VEM company, and domestic continuous winding production line still is in imitated stage and prematurity.A continuous winding production line has been introduced in initial stage nineties China Henan, and Shanghai Yaohua Fiber Reinforced Glass Plastic Co., Ltd. had introduced a continuous winding production line from VEM company in 2008, does not open owing to run into cost bottleneck market situation always.
No matter it is to adopt the dry method burning into sand to produce GRP pipe that Saudi Arabia AMIANTITTE company and Italian VEM company cost occupy high main cause, thereby this directly on the fiber after the glue spraying again the method for the sandblast high position that makes the resin content of screed be in 25-30% had influence on the whole cost of pipeline, owing to be open burning into sand method, pernicious gas impacts environment to cause sand dust to fly upward simultaneously simultaneously.
Wet method burning into sand technology is to realize that by last sand device screed coats the technology of twining by quartz sand graduation material and resin premixed back, its feature be the resin mortar layer mix, closely knit, the premix of finishing in airtight relatively space, the resin content of the little while screed of environmental impact factor can drop between the 12%-15%.
Owing to twine the particularity of production technology continuously, the domestic wet method that applies at present on the fixed length winding process can not be applicable to continuous winding production line, this inventor herein is developed a whole set of wet method burning into sand system by tackling key problem, and obtained good effect in process of production.
