Modification method of anti-corrosion and anti-crack ulmus pumila board

Abstract

The invention belongs to the technical field of wood treatment, in particular to a method for modifying anti-corrosion and anti-cracking white elm boards. The specific method is as follows: (1) immerse the cut white elm boards in superphosphate aqueous solution for heat preservation and soaking, take them out, and keep the temperature constant Refrigerate; (2) Immerse in boric acid aqueous solution and boil over medium heat, then continue to boil over low heat, take out the freezer and freeze at a constant temperature; (3) Hot press dry until the moisture content is 14%~16%, put it in a reaction kettle, add a treatment agent to The white elm board is submerged, steam-dried, vacuumized, and dried to a moisture content of 40% to 45%; (4) Freezing treatment, dried to a moisture content of 9% to 11%; the modified white elm board is sterilized and antiseptic Performance, not easy to absorb water, good moisture-proof performance, effectively reduce the loss rate of wood boards, and will not crack, warp, or fall off after 50 years of use, and has strong resistance to gravity, and is not easy to crack under high-strength pressure. It has high-efficiency anti-cracking ability.

Description

technical field [0001] The invention belongs to the technical field of wood treatment, in particular to a method for modifying anti-corrosion and anti-cracking white elm boards. Background technique [0002] Wood material, with natural texture and beauty, is widely used in construction, furniture and handicrafts and other fields. White elm material has good processing performance and polishing performance, with rough and uniform texture. It is an ideal material for high-end furniture. It is easy to cut and process, with high density, good gloss and beautiful appearance, but the white elm board is difficult to dry, has a large shrinkage, is easy to warp and crack, and has unsatisfactory anti-corrosion ability, which not only affects the appearance, but also reduces the strength of the board and shortens the life of the board. Service life, this is the fatal shortcoming of the white elm board; Contents of the invention [0003] In view of the problems referred to above, the...

Problems solved by technology

[0002] Wood material, with natural texture and beauty, is widely used in construction, furniture and handicrafts and other fields. White elm material has good processing performance and polishing performance, with rough and uniform texture. It is an ideal material for high-end furniture. It is easy to cut and process, with high density, good gloss and beautiful appearance, but the white elm board is difficult to dry, has a large shrinkage, is easy to warp and crack, and has unsatisfactory anti-corrosion ability, which not only affects the appearance, but also reduces the strength of the board and shortens the life of the board. This is the fatal shortcoming of the white elm board; therefore, it is urgent to invent a modification method of the anti-corrosion and anti-cracking white elm board
