Embodiment Construction
[0012] The specific implementation of the present invention will be further described below in conjunction with accompanying drawing:
[0013] figure 1 The construction flow chart of the present invention is provided. The steps are as follows:
[0014] Step 1, slurry mixing: calculate the amount required for making components, according to the following ratio: high-strength gypsum powder 100, glass fiber chopped strands and glass fiber roving 5, water reducing agent 0.3%, retarder 0.3 %, water 33. Take out the glass fiber roving and put it into the silo of the CNC nozzle, and put the rest of the ingredients into the mixer for about 20 seconds;
[0015] Step 2, Molding: According to the amount of glass fiber added and the thickness of the product, the amount to be added each time and the number of weaving times are obtained. In this embodiment, the product is a square grid, and its size is as follows: 1500×1500×120mm. According to the calculation, the slurry is poured in fo...

Abstract
The invention relates to a manufacturing method of a glass fiber reinforced gypsum ice grating plate, comprising the following steps of: prepared slurry mixing, moulding in a mould, demoulding, dehydrating and drying, wherein the step of moulding in a mould comprises the steps of: placing a model on a vibrating worktable, coating a layer of demoulding agent in a cavity of the model, pouring a certain amount of prepared slurry in the cavity of the model, heightening a numerical control nozzle or a manual tool to a certain height of a mould, sequentially weaving glass fiber twist-less thick yarn in the reversed space of the mould according to a direction given by the preset program, pouring a layer of the certain amount of prepared slurry after accomplishing one-layer laying, vibrating the worktable during pouring, repeating the program for many times, and improving the height of the control nozzle or the manual tool once after finishing the program every time. The manufacturing method of glass fiber reinforced gypsum ice grating plate, provided in the invention, fills a blank, finishes the history that the ice grating plate can not be made of glass fiber reinforced gypsum, and obtains obvious progress and economic benefit.
Description
technical field [0001] The invention relates to a decorative board for building materials, in particular to a method for manufacturing a glass fiber reinforced gypsum ice grid board. Background technique [0002] At present, with the rapid development of the economy and the improvement of people's living standards, people have put forward aesthetic requirements for most buildings, such as: the interior decoration of large buildings such as concert halls, grand theaters, and auditoriums requires the appearance of decorative panels The shape is unique, the surface is fine, gorgeous and not deformed, and it also requires light weight, high strength, fire prevention, environmental protection, and convenient installation. The preferred material for making such decorative panels is glass fiber reinforced gypsum. The inventor filed an application titled "Glass Fiber Reinforced Gypsum Board and Its Manufacturing Method" on September 29, 2007, and the Chinese Invention Patent Bulleti...
