specific Embodiment approach 1
[0046] Embodiment 1: A method for gluing a phenolic resin adhesive tape for manufacturing a bearing cage described in this embodiment is carried out according to the following steps:
[0047] 1. Prepare glue:
[0048] Pour the phenolic resin glue into the glue tank; after the phenolic resin glue is cured at a temperature of 103°C to 107°C for 1.5h to 2.5h, the solid content is 54% to 62%. Under the condition of 158°C-162°C, the gelling time of bonding copper sheets to copper sheets is 60s-90s, the free phenol content of the phenolic resin glue is ≤15%, and the specific gravity of the phenolic resin glue is 1.04-1.07;
[0049] Second, cloth preparation:
[0050] 109 Natural muslin cloth prepared for use in the rubber category;
[0051] 3. Turn on the dryer:
[0052] Turn on the dryer, and set the drying temperature of the three stages at 127°C to 133°C;
[0053] 4. Turn on and adjust the glue machine:
[0054] Turn on and adjust the gluing machine, the gap between the nip ...
specific Embodiment approach 2
[0095] Embodiment 2: This embodiment differs from Embodiment 1 in that: in step 3, the dryer is turned on, and the drying temperature of the three stages is set at 130°C. Others are the same as in the first embodiment.
specific Embodiment approach 3
[0096] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is: open and adjust the gluing machine in step four, the gap between the nip rollers is 0.19mm, adjust the rotation speed of the rollers so that the pointer of the ammeter is at 65A, And make the transmission speed of the transmission cloth 1.7m / min. Others are the same as in the first or second embodiment.
