Normal temperature extruding method of window curtain blade

Abstract

The normal temperature extruding process of window curtain blade includes cutting timber into sheet with proper shape, size and thickness; cleaning; compounding mixture liquid of methyl cellulose, water, calcium carbonate and adhesive in certain proportion; extruding the mixture liquid into forming mold inside a extruder while the timber sheet is fed into the mold to make the mixture liquid be painted to outside of the timber sheet; and stoving in some stoving equipment.

Description

technical field [0001] The present invention is related to venetian blinds, and more specifically refers to a method for extruding curtain blades at normal temperature. Background technique [0002] Press, generally the known curtain blade is to take natural wood or sawdust as its inner core layer, and on the outside of the inner core layer, form the surface layer with artificial chemical raw materials (such as plastics); For changes in different environments such as external temperature and humidity, the outer surface layer resists moisture deformation, and when the outside is heated and wants to warp, the core wood can provide pulling force to prevent the deformation of the outer surface layer , so that the two can check and balance each other, and prolong the service life of the curtain blade. [0003] Press again, see figure 1 The procedure for coating the surface of the curtain blade 1 is to first cut a piece of wood 2 to a suitable shape, size and thickness, and then...

Problems solved by technology

[0004] However, due to the manufacturing process of the aforementioned curtain blades, it is necessary to heat and heat the raw material mixture in the extruder first, so that the mixture can be evenly attached to the wood. In the case of continuous heating, not only will the entire production line be affected by the high temperature of the extruder and raw materials, but the work quality of personnel on the production line will be extremely poor, and the high temperature will not only increase the loss rate of machinery and equipment, but also be used for Equipment that generates high-temperature heating will also increase the cost of manufacturing, and due to the impact of high heat, the moisture in the wood will be lost, causing the wood to become brittle, making the quality and appearance of the finished product poor.
