Description

A kind of production method of the glass-fiber reinforced plastic grille with burning into sand layer
Technical field
The present invention relates to glass-fiber reinforced plastic grille technical field, the producer of specially a kind of glass-fiber reinforced plastic grille with burning into sand layer Method.
Background technology
It is to make matrix material, glass fibers using resin that glass-fiber reinforced plastic grille, which is also known as fiberglass reinforced plastics (FRP) grid, Dimension makees reinforcing material, by certain forming method carry out it is compound, assemble.It is resin according to used matrix material Difference, be divided into isophthalic grid, vinyl grid and phenolic aldehyde grid etc.;According to the difference of its forming method, it is divided into molding glass again Glass steel grating and dragging and squeezing glass fiber reinforced plastics grid.Molded Frp Grids are whole by glass fibre weaving, resin-cast molding Body forms, and has fabulous decay resistance;Pultrusion grid is by the way that after continuous fiber impregnating resin, pultrusion is heating and curing, even Continuous shaping assembles again, has higher intensity.
For a long time, offshore drilling platformses are one of main places that phenolic glass reinforced plastic grille largely uses, the U.S. Coast Guard has formulated a series of combustion testing standards, and its main standard is ASTM-E119, and the standard is divided into three-level, two level And one-level, every grade of test request to product are different.
1, grade III Standards are:1. according to naked light ignition temperature curve, high temperature naked light, which burns 1 hour, reaches 927 DEG C, grid Constantly, after ablation cooling in 1 hour, 40kg load can be carried on grid center 305mm × 305mm area.2. burning During, 40kg loads are loaded on grid center 305mm × 305mm area, survey is compared with the reja of regulation requirement Examination, when central point amount of deflection reaches (grid span/10), now ignition temperature difference is no more than 100 DEG C to two grids.
2, secondary standards are:1. grade III Standard must be passed through.2. having surveyed grade III Standard and by rear, grid must endure as 460kg/m2 average load and it is not broken.
3, primary standards are:1. secondary standard must be passed through.2. having surveyed secondary standard and by rear, at grid center 80kg .m impact momentum is born on 305mm × 305mm area and not broken.
Due to simple glass fiber, its softening point is less than 880 DEG C, when environment temperature exceedes its softening point, glass fibre Its due mechanical strength can be lost completely because of softening, i.e., according to strengthening material of the simple glass fiber as phenolic aldehyde grid Material, because of the limitation of glass fibre softening point, phenolic aldehyde grid will be made to lose due mechanical property and strong completely under burning condition Degree, thus elevated temperature strength requirement as defined in ASTM-E119 standard two levels and residual strength requirement can not be met, or even be not added with Under conditions of load, it can be broken because of Action of Gravity Field, so as to which this certification can not be passed through.
