Problems solved by technology

[0005] Aiming at the shortcomings of the existing glass steel pipes that consume a large amount of resin and have limited mechanical properties, the invention provides a production method for glass steel pipes. The inner surface of the produced glass steel pipes is smooth and free of cracks, delaminations, and pinholes. , impurity, poor glue area, air bubbles and fiber infiltration, etc., the end surface of the pipe is even, no burrs on the edges, and no obvious defects on the outer surface

Embodiment 1

[0043] The production method of glass steel pipe includes the following technical steps:

[0044] 1) Lining:

[0045] Prepare materials according to the type and specifications of the designed materials. The materials should be stacked neatly, safely and cleanly, and the materials should be strictly prevented from getting wet. The storage distance of accelerators and curing agents should not be less than 5 meters;

[0046] Remove the sundries on the surface of the mold, make the outer surface of the mold smooth and smooth, check whether the mold structure is in good condition, and whether the welding seam of the shaft head is open. , the thickness is in line with the design requirements, the mold needs to be waxed once for the first time or for several consecutive uses, and the waxing frequency is increased when demolding is difficult;

[0047] Prepare 50mm specification film according to pipe diameter requirements;

[0048] Apply the film, install the 200mm wide film on the...

Embodiment 2

[0068] The production method of glass steel pipe, compares with embodiment 1:

[0069] In the lining production of step 1), according to the pipe diameter requirements, prepare a 200mm specification film;

[0070] The accelerator is cobalt water, the curing agent is methyl ethyl ketone peroxide, the resin is selected from unsaturated polyester resin, and the inner lining resin is selected from bisphenol A type unsaturated polyester resin; accelerator, curing agent, reinforcing agent The mass ratio to resin is 0.3:3:2:100;

[0071] Other steps are the same as in Example 1.

Embodiment 3

[0073] The production method of glass steel pipe, compares with embodiment 1:

[0074] In the lining of step 1), according to the pipe diameter requirements, prepare a 100mm specification film;

[0075] The accelerator is cobalt water, the curing agent is methyl ethyl ketone peroxide, the resin is selected from unsaturated polyester resin, and the inner lining resin is selected from polyester resin or vinyl ester resin; accelerator, curing agent, reinforcing agent and The mass ratio of resin is 0.3:2:2:100;

[0076] Other steps are the same as in Example 1.

Abstract

The invention discloses a production method of glass steel pipes, which comprises the following technical steps: 1) lining; 2) winding; 3) curing: immediately after the winding is completed, the mold with the pipe is hoisted to the curing station, and the main shaft is started to make the mold in the Curing at a constant speed; 4) Trimming: Check the curing degree of the pipe, and when the Barcol hardness of the outer surface of the pipe is not less than 20, trim the socket, trim the socket, and surface treatment; 5) Demoulding: When the Barcol hardness of the outer surface of the pipe is When it is not lower than 25, demoulding is carried out, the burr of the pipe socket is completely cut off, the burrs at the end of the socket are polished, and the resin is evenly painted until it is cured. The glass steel pipe obtained by the production method of the present invention has a smooth inner surface without cracks, delamination, pinholes, impurities, glue-poor areas, air bubbles and fiber infiltration, etc. obvious flaws.

Description

【Technical field】 [0001] The invention relates to the technical field of FRP pipes, in particular to a production method of FRP pipes. 【Background technique】 [0002] The state supports the development of new building materials to reduce energy consumption and save energy. The use of glass fiber reinforced plastic building materials is an effective way to meet the national energy conservation policy and achieve energy conservation and consumption reduction.
