Embodiment

[0023] A boron-coating method with high efficiency and high boron utilization rate. The method specifically includes two steps of preparing a boron-coating liquid and boron-coating. First, when preparing the boron-coating liquid, select two 100ml and one 25ml beakers, respectively Numbering, then select two glass rods, number them separately, wash off industrial oil with alcohol, wash with deionized water, and dry for later use. The size and number of beakers can be adjusted according to specific needs.

[0024] Add 0.16g epoxy resin to No. 1 100ml beaker, then add 30g alcohol, and use No. 1 glass rod to stir fully to make the resin completely dissolve in alcohol; then add 1g nano boron powder to No. 2 100ml beaker, add 10g alcohol, Use No. 2 glass rod to fully stir to make it fully mixed with alcohol. The fat-to-boron ratio selected in this example is 0.16.

[0025] Add 0.0392g of curing agent to No. 1 100ml beaker, use No. 1 glass rod to fully stir and mix it evenly, then po...

Abstract

The invention discloses a boron coating method with high efficiency and high boron utilization rate. The boron coating method comprises the following steps that nano boron powder and an adhesive are correspondingly dissolved by using alcohol, the two solutions are mixed, and diluted by using alcohol to prepare a boron coating liquid; and a base material to be coated with boron is placed in a constant-temperature drying box, the boron coating liquid is horizontally laid on the base material to be coated with boron in a glass rod drainage mode, and boron coating of the base material is completed. According to the method, a certain amount of boron coating liquid containing boron powder with a certain concentration and the adhesive is flatly laid on the base material through liquid surface tension, boron coating is conducted in a constant-temperature drying box drying mode, the boron coating liquid is flatly laid on the base material through liquid tension, the uniformity of a boron film can be guaranteed, after the boron coating liquid is dried, the thickness of the boron film can be effectively controlled, and the utilization rate of the boron powder is close to 100%.

Description

technical field [0001] The invention relates to the field of neutron detection, in particular to a boron coating method with high efficiency and high boron utilization rate. Background technique [0002] Neutron detection and neutron imaging technologies are widely used in aerospace, homeland security, large neutron spectrometers, medical imaging, and neutron radiation protection. Neutrons themselves are not charged, and need to be converted into charged particles by using appropriate detection materials, combined with appropriate detector structure and readout electronics to extract the signal to realize the detection of neutrons. The most commonly used thermal neutron detection materials are 3 He gas, which has the advantages of large thermal neutron reaction cross section, high n / γ discrimination ratio, non-toxicity, high pressure, high neutron detection efficiency and easy realization of large-area detection, is widely used in various neutron detection fields . But th...
