Abstract
The invention provides a composite scale inhibition scale inhibiting, sterilizing and alga killing agent. The composite scale inhibition scale inhibiting, sterilizing and alga killing agent comprises 0.4-12wt% of polyaspartic acid, 0.4-10wt% of polyacrylic acid, 0.3-7wt% of isothiazolinone, and the balance of water. The composite scale inhibition scale inhibiting, sterilizing and alga killing agent is suitable for high pH value, low alkalinity, medium hardness and low concentration rate systemic air conditioner circulating water, and can effectively inhibit scales, sterilize and kill algae in circulating water treatment.
Description
Technical field
The present invention relates to a kind of industrial circulation water treatment pharmaceutical formulation, specifically a kind of composite scale Biocidal algae-killing agent.
Background technology
In mankind's water, water for industrial use account for very large ratio, and wherein industrial circulating cooling water account for about 75%, saves cooling water and plays a part water conservation very important.The main method of saving cooling water is recycle cooling water, control cycles of concentration well, but low cycles of concentration post-etching control etc., the calcium ion concentration in industrial circulating water and chlorine ion concentration etc. have and will increase, and bring the problem of fouling and corrosion and microorganism thereupon.The seventies to the eighties, processing method height pH water mainly adopted the pH added in hydrochloric acid reduction water, added the medicaments such as organic phosphate simultaneously and processed.Undesirable also not science in method actual motion in this, add excessive acid cause equipment to bore a hole and microorganism uncontrollable etc.Go out the nineties to adopt in 20th century general organic phosphate and chromate one system treatment effect good, environmental pollution is serious, microorganism very shortcoming rambunctious etc.The scale inhibition that only has described in current antisludging agent does not have inhibition and sterilization algae removal effect, and hardness generally reaches 150 ~ 420mg/l (with caco
3meter) basicity at 43 ~ 275mg/l (with caco
3meter), after hardness and basicity raise further, daily scale inhibition erosion slow fruit is very undesirable and cannot take into account sterilization, the ability of sterilization algae removal is taken into account in order to improve antisludging agent further, solution environmental pollution extremely control of microorganisms becomes current one large difficult point, and the present invention goes out a kind of scale inhibition Biocidal algae-killing agent for this Study on Problems exactly.
Summary of the invention
The invention provides a kind of scale inhibition Biocidal algae-killing agent, be applicable to high pH, the air-conditioner circulating water of end basicity, middle hardness, low cycles of concentration system, effective scale inhibition sterilization algae removal in circulating water treatment.
For achieving the above object, the invention provides a kind of composite scale Biocidal algae-killing agent, the percetage by weight of its component and each component is:
Poly-aspartate: 0.4%-12%;
Polyacrylic acid: 0.4%-10%;
Isothiazolinone: 0.3%-7%;
Surplus is water.
As further scheme, the percetage by weight of described its component of composite scale Biocidal algae-killing agent and each component is:
Poly-aspartate: 6.8%;
Polyacrylic acid: 5.2%;
Isothiazolinone: 3.7%;
Surplus is water.
The preparation method of described composite scale Biocidal algae-killing agent, as prepared the composite scale Biocidal algae-killing agent of 150kg, take poly-aspartate 10.2kg, polyacrylic acid 7.8kg, isothiazolinone 5.5kg and water 126.5kg, by poly-aspartate, polyacrylic acid, isothiazolinone is enough puts into water, is stirred to water-bed deposit-free.
Compared with prior art, the invention has the beneficial effects as follows: raw material of the present invention is all marketable material, easily obtain, product cost is very low, process enter medicament added by water per ton cost less than 1.25 yuan, and preparation method is simple, scale inhibition Biocidal algae-killing agent of the present invention is used for low cycles of concentration, high pH, there is good scale inhibition sterilization algae removal and take into account effect, effect can be taken into account with current open type industrial air-conditioning cycle water, scale inhibition performance of the present invention can reach 90.3.% after tested, sterilizing rate can reach 96.7%, and scale inhibition Biocidal algae-killing agent of the present invention can not accelerate carbon steel and copper and stainless corrosion can control microorganism well, therefore this scale inhibition Biocidal algae-killing agent is used for industrial circulating cooling water system, achieve industrial circulating cooling water zero-emission object, the life cycle of cooling water system and control of microorganisms can be extended, ensure carrying out smoothly of enterprise's long-term production safety, reduce enterprise's water for industrial use cost, for energy-saving and emission-reduction contribution etc. is made in country 12 plan.
