Embodiment 1

[0093] A kind of dipping method that present embodiment provides, it comprises the steps:

[0094] In step S1, the glass fiber mat is arranged in a roll shape;

[0095] Step S2, using high pressure to force the glue solution to flow through the glass fiber felt along the radial direction of the glass fiber felt roll.

[0096] In the above embodiment, more preferably, the glass fiber mat reel is placed horizontally, and the pressure value of the glue solution decreases gradually in the axial direction of the reel and in the direction extending from the middle of the reel to both ends thereof.

[0097] Specifically, in the radial direction of the glass fiber mat reel, the glue solution flows from the inside of the reel to the outside thereof, or the glue solution flows from the outside of the reel to the inside thereof. In the axial direction of the reel, the pressure value of the glue is normally distributed. When dipping, alternately input the glue solution from both ends of...

Embodiment 2

[0102] Such as Figure 1-7 As shown, this embodiment discloses a dipping equipment, which includes: a rubber injection sleeve 20, a pressure barrel 30 and a pump body 40;

[0103] The pressure-bearing barrel 30 is set outside the injection sleeve 20, and an annular cavity for accommodating the glass fiber felt reel is arranged between the two;

[0104] Such as image 3 As shown, the outer circular side of the injection sleeve 20 is provided with an injection hole 24 communicating with the inner and outer sides of the injection sleeve 20;

[0105] Such as figure 2 As shown, the outer circular side of the pressure barrel 30 is provided with a glue discharge hole 31 communicating with the inside and outside of the annular cavity;

[0106] The glass fiber felt is wound on the injection sleeve 20 to form a glass fiber felt roll;

[0107] The pump body 40 communicates with the cylinder cavity of the glue injection sleeve 20 through a pipeline, and is used to inject glue into th...

Abstract

The invention provides a gel dipping method. The method includes the steps that S1, glass fiber felt is arranged like a coil; S2, gel liquor is made to flow through the glass fiber felt in the radialdirection of the glass fiber felt coil under high pressure. The method has the advantages that full-coil production can be realized, and the product length is not limited by the length of a gel dipping device; besides, bubbles in the glass fiber felt are quickly discharged, then the gel liquor uniformly dips the glass fiber felt, and the production efficiency is improved by 30%.

Description

technical field [0001] The invention relates to the technical field of rubber mats, in particular to a dipping method for dipping glass fiber felts. Background technique [0002] Airgel felt is made of silica airgel as the main raw material, which is mixed with ordinary glass fiber. This product improves the 400°C high temperature resistance limit of ordinary glass fiber, and its thermal insulation performance is 3 to 8 times that of traditional materials. It can withstand high temperatures above 700°C and is flat, mechanically resistant, and easy to process. Its thermal conductivity is extremely low. It is a new type of material in the field of industrial thermal insulation applications. [0003] The existing dipping method is mainly to unfold the glass fiber felt roll and lay it flat in the cuboid gel tank as equipment for horizontal gel dipping. The size of the gel tank is 15m*2m*0.65m, which can hold 15m 3 Liquid, the glass fiber mat roll is spread flat in the gel tank...
