It holds at high temperature, it is necessary to use the antisludging agent that can be used for a long time at high temperature.In addition, since antisludging agent is built in water heater
In, ordinary user is difficult to self-changeable antisludging agent, when antisludging agent exhausts, it is necessary to which by specialized maintenance, personnel are supplemented.This is wanted
The service life of antisludging agent is asked to have to grow, it is inconvenient to user's bring to reduce frequently supplement antisludging agent.
Secondly antisludging agent particle is placed in the liner of water heater, can occupy the water space of liner, antisludging agent particle
The amount of placement is more, then the antisludging agent service life will be longer, and the space for occupying liner is bigger, it is desirable that in tank body as small as possible
The antisludging agent particle of built-in sufficient amount, but the density of antisludging agent particle packing is excessive, it will cause crossing, water is obstructed, equally
Influence the scale inhibition effect of antisludging agent；
The purpose of the invention is to provide a kind of antisludging agent particle.The purpose is to solve above-mentioned technical problem.Meanwhile this
The antisludging agent particle of invention can prevent Particle Breakage, so that antisludging agent ingredient be avoided to be washed away by water flow.The purpose of the present invention is also
It is to improve the service life of antisludging agent particle.In addition, the present invention also provides a kind of antisludging agents with specific structure.Pass through
Make antisludging agent of the invention that there is specific structure, antisludging agent of the invention can be made uniformly to discharge from antisludging agent particle, improves
Scale inhibition effect extends and uses the time.
The purpose of the present invention also provides a kind of water heater, and the built-in antiscaling device in its liner, antiscaling device is provided with resistance
Dirty agent particle configures the parameters such as the shape, structure, the weight of antisludging agent, the weight of adhesive of antisludging agent particle, protects
Tank body has been demonstrate,proved equipped with the preferable scale inhibition effect that has of antisludging agent particle of antisludging agent particle region unit area and service life and
Occupied space is less.
Technical solution
The present invention provides a kind of antisludging agent particle, the scale inhibition particle includes antisludging agent and adhesive, the antisludging agent
Content be 60%~98%, preferably 60%~95%, the content of described adhesive is 2%~40%, preferably 5%~
40%, solubility of the antisludging agent in 90 DEG C of water below is lower than 5g/100g, at 90 DEG C or less after described adhesive solidification
Water in solubility be lower than the solubility of the antisludging agent, the particle in 90 DEG C of degree with swellbility in being lauched lower than 12%,
It is lower than 1% after described adhesive solidification to be lauched middle degree of hydrolysis for 90 degree.
In antisludging agent particle of the invention, by reducing the content of adhesive, antisludging agent can be increased to greatest extent
Content, to extend the service life of antisludging agent particle.But increase the content of antisludging agent merely, it is strong to will lead to antisludging agent particle
Degree is insufficient, easily broken.For this purpose, and making inventors have found that be lower than the antisludging agent of 5g/100g water by Selective dissolution degree
The solubility of adhesive while controlling antisludging agent particle at 90 DEG C with swellbility in being lauched further below the solubility of antisludging agent
Lower than 12%, and select after solidifying to be lower than at 90 DEG C with degree of hydrolysis in being lauched 1% adhesive, can antisludging agent be dissolved out
When, adhesive still maintains its skeleton structure, to extend the use time of antisludging agent particle.
