[0033] Table 1 The formula for preparing dry ash cement

[0034]

[0035] (1) Preparation of dry ash binder

[0036] First, prepare the water-reducing agent solution 48 hours in advance according to the proportion of 23.1wt%; then weigh the cement, sea sand, silica fume, water, quartz whiskers and water-reducing agent solution in proportion; pour the sea sand and quartz whiskers into the hourglass ;Pour the water into the mixing bucket, then pour the cement and silica fume, turn on the stirring button, and stir at a speed of 300rpm, after 120s of mixing time; the sea sand automatically flows into the rotating mixing bucket at a constant speed, and stirs at a speed of 300rpm 120s; stop the mixer, pour in the water-reducing agent solution, and use a scraper to scrape off the cement or sea sand that has not been stirred by the mixing blades and the barrel wall; restart the mixer after 60s, and quickly stir at a speed of 1300rpm for 120s, then at a speed of 100rpm Stir slowly ...

Abstract

The invention relates to a dry ash adhesive for adhesively assembling pillar porcelain insulators, a preparation method and application thereof, and belongs to the technical field of pillar porcelain insulators. The dry ash cement for cementing pillar porcelain insulators according to the present invention includes the following raw materials in parts by mass: 1 part of cement, 0.55-0.60 parts of aggregate, 0.24-0.26 parts of water, 0.01-0.025 parts of silica fume, and a water reducer The solution is 0.019-0.023 parts, and the ceramic whisker is 0.001-0.018 parts. The dry ash cement for cementing pillar porcelain insulators according to the invention has a simple and scientific formula design, the prepared cement has a fast final setting time, high early strength, no delamination in the section of the test strip, and stable product quality, which solves the problem of pillar porcelain insulators. Loosening, abnormal noise and pull-out problems caused by dry shrinkage or low strength of the adhesive; the invention also provides a simple and easy preparation method and application, which is beneficial to industrial production.

Description

technical field [0001] The invention relates to a dry ash adhesive used for glue-packing pillar porcelain insulators, a preparation method and application thereof, and belongs to the technical field of pillar porcelain insulators. Background technique [0002] Gluing refers to the method of permanently joining two or more insulating parts and accessories with adhesive. In the current assembly process of pillar porcelain insulators, cement adhesive is used as a filling material for glue connection. [0003] The commonly used glue installation method in China is to fix the flange and porcelain parts on the glue installation frame in advance, measure the positioning and lock the frame body; then mix cement and aggregates such as natural sea sand and other materials to be as fluid as water. Slurry adhesive, commonly known as thin ash, pour the thin ash into the long spout pot, while the worker gently tilts the glue mounting frame with his feet to a certain angle, while holding ...
