Abstract
The present invention provides a kind of noise reduction balancing weight for washing machine, it is related to washing machine counter weight field, by weight, heated after 10 parts of cement mortar, 0.5 part of gypsum mortar, 10 parts of old metal broken particles, 1 part of foaming agent are carried out into uniform stirring, and be poured into mould, after supercooling, solidification both.A kind of noise reduction balancing weight for washing machine provided by the invention, while solving the problems, such as counterweight, washing machine caused noise at work is also reduced, so as to reduce noise nuisance.
Description
Technical field
The present invention relates to balancing weight field, and in particular to a kind of noise reduction balancing weight for washing machine.
Background technology
Washing machine internal is designed with balancing weight, washing machine is had certain weight, for reducing washing machine worked
Vibrations in journey and rock, ensure its stable and balance.
But washing machine can make a noise unavoidably in the course of the work, when washing machine operates, due to washing inner drum and fuselage
Collision is produced among shell, after having been grown when can send bang pop sound, and use, due to wear and tear in machines, gloss oil not
Various abnormal noise and vibrations, can all occur in the reasons such as foot, parts aging, camber of spring.
Noise can give people to bring physiology and psychological harm：Hearing damage, harmful and people cardiovascular system, influence people
Nervous system, make one being irritable and getting angry easily, influence sleep, cause it is tired etc..
Balancing weight is no decrease of noise functions in itself, if a kind of balancing weight for being accompanied with noise reduction can be produced,
And be of practical significance very much.
The content of the invention
Present invention aims at a kind of noise reduction balancing weight for washing machine is provided, to solve the above problems.
The present invention takes following technical scheme to solve the above problems：
The invention provides a kind of noise reduction balancing weight for washing machine, it is characterised in that by weight, by 10 parts of water
Cement mortar, 0.5 part of gypsum mortar, 10 parts of old metal broken particles, 1 part of foaming agent heat after carrying out uniform stirring, temperature 50-
270 DEG C, heat time 30min, and be poured into mould, after supercooling, solidification both.
Preferably, 0.5 part of Cement mortar hardener, the system of the Cement mortar hardener are added in described cement mortar
It is as method：By weight, by 1-2 parts sodium carbonate, 3-5 parts copper sulphate, 15-20 parts stearic acid, 9-12 parts sodium hydroxide, 6-
9 parts of calcium chloride, 0.5-0.8 part sodium fluorides add 500-700 parts water both to be obtained after mixing.
Preferably, described foaming agent is sodium acid carbonate.
Preferably, described heating-up temperature is 135-140 DEG C.
Preferably, described mould is cylinder, and a diameter of 30cm, thickness 5cm, the upper surface of mould is uniformly distributed
Hemispherical hole.
Cement mortar and gypsum mortar all have the property of sound absorption, and gypsum mortar has stronger cementitiousness, and
Cement mortar can make it that the balancing weight for preparing is harder firmly after being sufficiently mixed, at the same cement mortar also have it is larger close
Degree, it is most suitable to make balancing weight, coordinates old metal broken particle using can greatly reduce cost of manufacture.
Described Cement mortar hardener can greatly improve the hardness of cement mortar so that the balancing weight of preparation has anti-
Water, prevent the characteristics of molten, so balancing weight will not produce fragmentation, situation about peeling off because of the environment of humidity at work, prolong significantly
The usage time of balancing weight is grown.
Sodium acid carbonate can discharge carbon dioxide when being heated to more than 50 DEG C, and using this property, sodium acid carbonate is added
Into cement mortar, gypsum mortar, old metal broken particle and be heated to 100 DEG C -140 DEG C balancing weight surfaces that can make shaping into
Hole, increase absorption area.
Mould is cylindrical, a diameter of 30cm, thickness 5cm, and the upper surface of mould has equally distributed hemispherical to cheat, this
The structure of sample also can increase the upper surface area of balancing weight, further increase absorption area.
The beneficial effects of the invention are as follows：
The invention provides a kind of noise reduction balancing weight for washing machine, while solving the problems, such as counterweight, also reduce
Washing machine caused noise at work, so as to reduce noise nuisance.
