Content brief introduction: Industrial in water gross, cooling water occupies very large proportion, especially petro-chemical enterprise and enterprise of large chemical industry, occupy total water consumption almost 80, 90 ％ , use dc water to undertake cooling, will cause the serious waste of water natural resources, use circular water to undertake cooling commonly so. Such will managing many industrial water, the current society that is in short supply increasingly in fresh water resource especially, have very important real significance. However, when cooling water is used repeatedly, as a result of water evaporate cause deliquescent salt kind condense wait for a reason, bring corrode, the knot dirties and stick the problem such as mud, many more serious than using dc cooling water to want. Can make the current obstruction of heat exchange equipment is increased so, the power consumption of water pump increases, conduct heat loss of efficiency, make craft condition is in abnormal condition, bring huge loss to production, to prevent the happening of these phenomena, can use stabilizing agent of cooling water water quality, realize the repeated usage of cooling water thereby.
In light of the block dirty agent that develops domestic and internationally at present, great majority is phosphor (phosphine) acerbity kind or sulphur is acerbity kind of block dirty agent, phosphor (phosphine) acerbity Cheng Zhenglin acid can promote hydrolyze of kind of block dirty agent the breed of alga of the bacterium in the system, and cannot effective inhibition Ca3(P04)2 and Zn dirty, and solve the problem such as Fe2O3 deposit, be opposite on together with environmental protection again the limitation of P, the application of agent of dirty of this kind of block is restricted certainly, sulphur is acerbity dirty agent has kind of block stronger block CaC03 and Ca3(P04)2 ability, the synthetic condition of agent of dirty of this kind of block is controlled not easily, yield is inferior, make cost raises thereby, also make its application is restricted certainly, current, main to with carboxylic acid kind the respect of block dirty agent that is main monomer develops.
Our complex is the carboxylic acid that a kind of 3 monomer do not contain P kind block dirty agent, through the experiment we discover, agent of dirty of this kind of block divides the common characteristic that has agent of other block dirty: If need those who count Ppm to cast only,expect can prevent all sorts of common furring in circular cooling water effectively generate, still have oneself distinct advantage, the Zn in can very good stable water, to FezOs, stick mud to wait to also have very good dispersive action, can applicable wait for different water quality with tall hardness, tall alkalinity, tall PH, to handle Gao Nong to shrink diploid circular cooling water offerred a likelihood, itself is avirulent, but by biology degradation, satisfy the requirement on environmental protection, processing cost is very low, it is one kind compares the good block dirty dose that can be used at circular cooling water.
