Embodiment Construction

[0019] Below in conjunction with embodiment, the present invention will be further described:

[0020] 1. The production method of water-based attapulgite suspending agent is:

[0021] Mix attapulgite clay, bentonite, magnesia, sodium silicate and sodium carboxymethyl cellulose according to the ingredients requirements, and then input them into the immersion pool and add water for immersion, and the immersion time is controlled at 48 hours; the soaked mixture is input to the Extruded by a roller machine into flakes, the thickness of the flakes is controlled at 0.5-1.5mm; the flakes are transported to the cement drying yard for drying, and the water content of the flakes after drying is ≤13%, and they are input into the mill for grinding Powder, particle size ≤0.044 mm, packaged as finished product.

[0022] 2. The ingredients of the water-based attapulgite suspending agent include the following components by weight percentage: 80% of attapulgite clay, 10% of bentonite, 3% of ...

Abstract

The invention relates to a method for producing mellow concave-convex rod suspension. Wherein, it comprises mixing convex-concave rod clay, magnesia, sodium silicate, and macrogol, emerging in emerge pool, compressing in rolling machine, drying, grinding in grinder, and packing. The invention has low cost without using water in preparing casting coat, with suspension rate, non deposit, and high anti-adhesive property.

Description

Technical field: [0001] The invention relates to a suspending agent, in particular to a production method of a water-based attapulgite suspending agent. Background technique: [0002] Water-based suspending agent has the characteristics of high production efficiency, low price and wide application range. It has been widely used in foundry production in my country. However, there are many problems with water-based suspending agent, mainly for the production of High-quality casting coatings are prone to precipitation during long-term storage and transportation, followed by serious coating brush marks, which affect the surface quality of castings. [0003] A good dispersing and suspending agent can not only effectively ensure the dispersion uniformity of each component of the paint and the suspension effect of the paint, but also improve the brushability of the paint, facilitate application, and improve the surface quality of the coating and castings. At present, the main raw m...
