Description

The wet method burning into sand system of continuous winding production line and manufacturing process
Technical field
The present invention relates to chamber for fibre-reinforced plastics sand inclusion pipe winding machine technical field, under being particularly applied to continuous winding process conditions, manufacture fiberglass reinforced plastics wet method sand-inclusion pipeline system and manufacturing process.
Background technology
Produce chamber for fibre-reinforced plastics sand inclusion pipeline in the world at present, mainly contain three kinds of moulding process: definite-length-winding process, continuous winding technique and spun casting technique:
1) definite-length-winding process is on the pipe die that length is certain, adopts spiral winding and/or hoop winding process in pipe die length, successively manufacture a kind of production method of tubing from the inside to the outside.
2) spun casting technique glass fibre, resin, quartz sand etc. is cast in the mould that is rotating by certain requirements with feeding machine, a kind of production method of formation tubing after solidification.
3) continuous winding technique is on the mould exported continuously, resin, continuous fiber, chopped strand and quartz sand is adopted the continuous laying of hoop winding method by certain requirement, and cut into a kind of production method of the pipe material product of an irregular length after solidification.
In domestic market, dominate is that fixed length winding method produces GRP pipe, and its main feature is that cost of investment is low, and turnover is fast, but there is the drawback that automaticity is not high, production efficiency is low, ambient influnence is large simultaneously.
Continuous winding production line has the overall merit that automaticity is high, steady quality, environmental impact factor are little, but there is the feature that cost of investment is high, product cost is high simultaneously.
The producer producing continuous winding production line at present in the world mainly contains AMIANTITTE company of Saudi Arabia and Italian VEM company, and domestic continuous winding production line is still in the imitated stage and prematurity.Initial stage nineties China has introduced in Henan a continuous winding production line, and within 2008, Shanghai Yaohua Fiber Reinforced Glass Plastic Co., Ltd. has introduced a continuous winding production line from VEM company, does not open owing to running into cost bottleneck market situation always.
Occupying high main cause regardless of AMIANTITTE company of Saudi Arabia and Italian VEM company cost is adopt dry method burning into sand to produce GRP pipe, the method of this directly sandblasting again after glue spraying on fiber makes the resin content of screed be in a high position of 25-30% thus have influence on the holistic cost of pipeline, simultaneously owing to being open burning into sand method, cause sand dust to fly upward pernicious gas simultaneously and environment is impacted.
Wet method burning into sand technology be by quartz sand graduation material and resin premixed after to be realized the technique of the coated winding of screed by upper sand device, its feature be resin sand pulp layer mix, closely knit, complete premix in relatively airtight space, the while that environmental impact factor being little, the resin content of screed can drop between 12%-15%.
Due to the particularity of continuous winding production technology, the domestic wet method applied at present on definite-length-winding process can not be applicable to continuous winding production line, by tackling key problem, a whole set of wet method burning into sand system be have developed to this inventor herein, and achieve good effect in process of production.
