Description
Technical field
The present invention relates to mitigation and antiscaling technology field more particularly to a kind of scale inhibition pipe and its production technologies.
Background technique
In plumbing field, as the long-time of pipeline uses, it is easy to produce scale.The especially discharge of domestic water
In water, once generating scale, it can cause harm to the human body.Because scale is a kind of difficulty soluble salt, either calcium carbonate, magnesium carbonate
The scale of the scale or calcium sulfate of form, magnesium sulfate form, it is to cause heart kidney stone, gallbladder that human body, which all can not be absorbed and be decomposed,
The arch-criminal of calculus, cardiovascular disease.Scale not only causes very major injury to human body, in the industrial production, can also endanger each
Kind of heat exchange, heating equipment and pipeline such as cause equipment damage or scrap, or even cause boiler be also at equipment explosion with pressure, the scale
The most basic reason of energy consumption waste.
In this regard, the removal to scale is realized using FOF antisludging agent in the prior art.FOF antisludging agent is one kind by French state
The main component that research institute, family develops is the environment-friendly products of organic salt, with efficient scale, environmentally protective, superpower stabilization
Many advantages, such as property.The scale inhibition principle of FOF antisludging agent is that scale is generally formed since small Crystallization, brilliant
Body is precipitated from supersaturated solution, there is nucleus formation and two links of lattice growth, and each link is divided into three growths
Phase, i.e. initial stage, mid-term, latter stage.That is, nucleus can just gradually form lattice after these three growth periods, lattice
Growth is a slow process, and only on certain activating areas of nucleus, adsorption precipitation ion, lattice could be grown, and
Crystal, that is, scale are being gradually formed by three growth periods.The budding period that FOF is grown in scale, i.e. scale nucleus are formed
Initial stage, the forming process of scale nucleus is just directly participated in and interfered in the form of ion, is distorted its nucleus, thus
The formation of nucleus is hindered in the puberty, and then effectively prevents the formation of crystal.Meanwhile FOF antisludging agent enter water after will not
Change water quality, it is small on raw water pH influence, be conducive to the characteristic for keeping raw water.
However, FOF antisludging agent is used in combination with active carbon at present when removing scale removal using FOF antisludging agent,
It is uneven in the presence of mixing, and the FOF antisludging agent for being attached to activated carbon surface is easy to fall off the problem of forming impurity.Therefore, for
The above problem, it is necessary to further solution is proposed, to avoid the generation of scale.
