Problems solved by technology

[0007] In order to solve the problem of the repaired FRP water pan in the maintenance method of the existing FRP water pan, the wear and tear exposes the original base material and the heterogeneous repair layer; completely solve the problem of cracks and water leakage at the junction of the stainless steel toilet and the FRP water pan; and manually repair the toilet The renovation of embedded parts such as floor drains and floor drains has caused the problem that the exposed decorative surface of the FRP water tray is damaged and untidy and beautiful. This invention proposes a renovation method for FRP water trays.

Embodiment Construction

[0044] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0045] The renovation method of FRP water tray includes the following steps:

[0046] Step 1: Grinding the surface of the FRP water tray to remove the non-slip bosses and the glue-opened, layered, and damaged surface. After polishing, the surface is smooth and smooth, and the inclination meets the requirements of the drawings or prototypes; Water storage, as long as it conforms to the slope of the prototype or drawing, and the water filling test does not need to store water;

[0047] Step 2: Overhaul the pre-embedded pipes, floor drains, and toilets of the FRP water tray. If damaged, perform step 3 to remove and replace the damaged embedded parts; if not damaged, clean and polish the embedded parts, and perform step 3 Four;

[0048] Step 3: Remove and update the embedded parts, the specific steps are:

[0049] a) After dismantling the pre-buried pipes, flo...

Abstract

The invention relates to a glass fiber reinforced plastic water disc renovating method, and belongs to the technical field of overhauling of glass fiber reinforced plastic water discs for rail vehicles. The problems that in the prior art, the color of the overhauled abraded position of the glass fiber reinforced plastic water disc is different from the color of the non-abraded position, cracks exist at the connecting position of a stainless steel toilet stool and the glass fiber reinforced plastic water disc, water leaks, and the problem that manual repairing is carried for renovating of embedded parts such as the toilet stool and a floor drain, and consequently the exposed decoration face of the glass fiber reinforced plastic water disc is damaged and is irregular are solved. The glass fiber reinforced plastic water disc renovating method includes the following steps that polishing is carried out to remove an anti-sliding boss of the glass fiber reinforced plastic water disc, the polished surface is flat and smooth, and the surface gradient meets the drawing paper or prototype requirement; the glass fiber reinforced plastic water disc embedded pipe, the floor drain and the toilet stool are overhauled, if damage occurs, the damaged embedded pieces are removed and renovated, and if damage does not occur, dirty removal polishing treatment is carried out; a new anti-sliding layer is manufactured; the anti-sliding layer is cut according to the size of the to-be-pasted face of the glass fiber reinforced plastic water disc, the exposed embedded piece and the toilet stool; the newly-manufactured anti-sliding layer is pasted to the glass fiber reinforced plastic water disc with the surface polished to be smooth; and the internal surface of the pasted glass fiber reinforced plastic water disc is sprayed with a gel coating.

Description

technical field [0001] The invention belongs to the technical field of maintenance of FRP water pans for rail vehicles, and in particular relates to a method for refurbishing FRP water pans. Background technique [0002] Most of the water trays in the toilets, washing rooms, tea stoves and sanitary ware rooms of railway passenger cars are made of glass fiber reinforced plastics. The wear and tear caused by the operation and maintenance of the vehicles, and the corrosion and other damage caused by the humid environment will seriously damage the glass fiber reinforced plastic water trays. It may lead to water leakage of the glass fiber reinforced plastic water pan. In severe cases, the internal corrosion may cause the surface of the water pan to collapse, which brings great difficulties to maintenance. The maintenance cost of the vehicle is increased, and the repair of the anti-skid boss by the general maintenance method cannot be neat and beautiful, so it is particularly impo...
