[0005] 2. This kind of board uses zinc powder to generate air bubbles in the manufacturing process to make the inside of the board have pores, so as to achieve the effect of heat preservation, sound insulation and light weight. This method is difficult to control the process and the production cost is high.

Embodiment Construction

[0042] The raw material weight percentage of the ionizing ray shielding protective plate of the present invention is shown in Table 1.

[0043]

[0044] Combined reference figure 1 , The method of manufacturing ionizing ray shielding protection board according to the raw material ratio in Table 1, includes the following steps:

[0045] Step A, prepare raw wood pulp

[0046] A1. Put the raw wood pulp cardboard into the hydraulic loosening machine and add water to loosen it;

[0047] A2. Refined by a refiner to obtain raw wood pulp;

[0048] A3. The raw wood pulp is sent to the slurry storage tank for slurry storage and homogenization.

[0049] Step B, mixing pulping

[0050] B1. Cement, rare earth composite powder, barium sulfate powder, mica, siliceous lime, expanded perlite and the raw wood pulp (equivalent to raw wood pulp cardboard) of step A are respectively measured according to the proportions in Table 1 and then poured into a hydraulic beater to mix. Mixed pulp

Abstract

The invention relates to a plate with an ionizing ray (X-ray or gamma-ray) radiation protecting function and provides an ionizing ray shielding protective plate. The protective plate comprises the following raw materials in percentage by weight: 7-10 percent of raw wood pulp material, 10-15 percent of cement, 2-5 percent of rare earth composite powder, 60-80 percent of barium sulfate powder and asmall amount of auxiliary materials (mica, aedelforsite and expanded perlite). A manufacturing method of the protective plate comprises the following steps of: preparing raw wood pulp; pulping by mixing; sizing; preparing a molded blank; reshaping and stacking; preparing a molded plate; initially curing; performing steam curing; drying the plate; performing post processing; and the like. The ionizing ray shielding protective plate has dual X-ray and gamma-ray protecting effects, high intensity and light weight, and can be used for replacing a lead plate. The raw materials used in the manufacturing method are sufficient, the foaming procedure in the production process is eliminated, the equipment and the process are simple, and the manufacturing cost is low.

Description

Technical field [0001] The invention relates to an ionizing ray shielding protection board, in particular to a board with the function of shielding and protecting X-ray or γ-ray radiation. Background technique [0002] Commonly used medical equipment includes X-ray detectors and gamma-ray treatment instruments. In some industrial productions, gamma-ray meters are commonly used as detection tools. When using these equipment, necessary shielding and protective measures should be adopted to prevent ionizing rays (X-rays or gamma rays). Radiation) to the outside world to avoid unnecessary human injury. [0003] The traditional X-ray protective board mainly uses the lead in the board to prevent X-ray radiation. The board itself contains the highly toxic substance lead, and has a high density and heavy weight, which is very inconvenient for transportation and construction. To this end, the relevant technicians have designed an X-ray shielding decorative board as disclosed in the patent-...
