Formula and processing technique for novel halogenide-cumming resistant magnesite greenhouse skeleton

Abstract

The invention relates to a formula and processing technique for a composite material product, in particular to a formula and processing technique of a novel halogenide-cumming resistant magnesite greenhouse skeleton. The formula is characterized by comprising the following components in percentage by weight: 58 percent of craft-level magnesium oxide of which the content of magnesium oxide is 85 percent, 21.6 percent of craft-level magnesium chloride of which the content of magnesium chloride is 56 percent, 2 percent of polyvinyl alcohol, 0.6 to 1.6 percent of organic silicon water repellent, proper amount of 5-mesh-below fiberglass roving, and 17.5 percent of water. The complex formula and the technique of using the organic silicon water repellent to replace magnesium sulfate to realize hygroscopic absorption and inhibit the halogenide-cumming of magnesite products are adopted, so the process is simplified and the cost is lowered. The organic silicon water repellent can form a fine water repellent film on the surfaces of pores in the magnesite product, the inner surfaces of capillaries of magnesite product and the surfaces of the magnesite products. The film can also react with carbon dioxide in air to form a carbonizing film with stronger hydrophobic property.

Description

1. Technical field [0001] The invention relates to a formula and a processing technology of a composite material product, in particular to a formula and a processing technology of a novel anti-refrosting magnesite greenhouse framework. 2. Technical background [0002] As we all know, magnesite products, also known as magnesium oxychloride cement products, have the characteristics of fast setting and hardening, strong cohesive force, weak alkalinity, and high strength. Shortcomings or deficiencies. The latest magnesite greenhouse framework with application number 200520121956.3 only adopts technical measures to reduce self-weight with polystyrene foam core, which does not solve the problem of halogen return and flooding; liquid, the chemical raw materials used reach more than 10 kinds, the composition and process are complicated, and the cost of equipment and process is high; the formula and processing technology of the magnesite cement greenhouse skeleton with the applicati...

The latest magnesite greenhouse framework with application number 200520121956.3 only adopts technical measures to reduce self-weight with polystyrene foam core, which does not solve the problem of halogen return and flooding; liquid, the chemical raw materials used reach more than 10 kinds, the composition and process are complicated, and the cost of equipment and process is high; the formula and processing technology of the magnesite cement greenhouse skeleton with the application number 01123570.5, its moisture absorbent adopts magnesium sulfate, although the product The shortcomings of moisture absorption and frosting have been improved, but it must be added to the mixture of pulp and glass fiber to prevent shrinkage and cracking of the product. The strength of the product has decreased, and it will deform after long-term use. The effect is not good, and it is necessary to improve
