Abstract
A kind of bactericidal particles for treating water is prepared from the exudative plastic resin (low-density polyethene resin), sterilizing iodine powder and anionic exchange resin.
Description
Technical field
The invention belongs to the sterilant field, relate in particular to a kind of bactericidal plastic particle and working method thereof.
Background technology
Always, the method for disinfection in the water is to use the material that adds soup, ultra-violet sterilization, light-catalysed Ceramic Balls and use the antibiotic drug that adds copper and silver system in plastics from ancient times.It is very big to human body harm to add soup.About ultra-violet sterilization and light-catalysed Ceramic Balls sterilization, if there is not light source just to be difficult to the performance effect, so aspect cost and the big or small aspect of device, relatively lack practicality.In plastics, contain in the antiseptic-germicide material of copper and silver system, no matter the amount of bacterium how much, frequent loss cupric ion of meeting and silver ions are so Hen Nan Zai Long is in the time, along with the performance effect that the environmental change of bacterium number continues, the result keeps effect in can only be between the short-term of bringing into use.
The sterilant that uses in liquid, majority are that the soup that chlorine is and oxygen is is dissolved in the method for using in the water.Most harmful and dangerous.Exist that the skin that makes human body is coarse, the fearful part of aspects such as the ventilation when using and keeping method.In addition, very miscellaneous at management aspect, must regularly in water, drop into soup continually, otherwise just can not keep hygienic state.Use the raw material of the antiseptic-germicide that contains copper, silver system in lower light-catalysed Ceramic Balls of danger and the plastics, sterilization effect is very weak, the long-term lasting effect of shortage.
In contrast, iodine is the functional group in conjunction with anionite-exchange resin owing to exchange group with basic anion, has the character of the Yin Li Jiao Change resin of positively charged.Biological Fine born of the same parents such as bacterium are contained a large amount of nucleic acid in inside, and near the surface, owing to contain acidic amino acid, cytolemma is in electronegative state.Iodine attracts electronegative bacterium, microorganism in conjunction with anionite-exchange resin, according to ion exchange principle, make iodine (I
2) free its germicidal action of performance.
This principle only reacts in the presence of bacterium and microorganism.According to the amount of bacterium, microorganism, the situation that regular iodine runs off so can not take place in the sterilization of carrying out in conjunction with iodine dissociates.It has to continue carrying out fungicidal property in the water system environment is characteristic.
Owing to the particle diameter about 0.5mm of iodine in conjunction with Yin Li Jiao Change resin, and the particle diameter that uses in liquid is very little, so run off in liquid in order to prevent, the sieve mesh of wrapping material and container must be made very thin.Control entering of sterilization object water by making very thin wrapping material and very close-meshed container, avoid iodine in conjunction with the contacting of Yin Li Jiao Change resin and bacterium, thereby effect is greatly reduced.
Also exist two shortcomings on the other hand: if, just can not provide to continue and effective sterilization effect promptly not along with the environment and the bacterium of sterilization object water system are measured, the structure of recycle unit changes intrinsic sterilizing ability, shape, the size of sterilant; Under the situation that the mobile water system is used, because sterilant and sterilization particulate size can hinder current.
Summary of the invention
The present invention is intended to solve the deficiencies in the prior art part and provides the environment of a kind of sterilization effect and object water system, bacterium amount to adapt sterilization longer duration, bactericidal plastic particle satisfactory for result and working method thereof.
The object of the present invention is achieved like this: the present invention is being processed into the sterilization particle with exudative Plastic Resin, the Powdered iodine with sterilizing function and the anionite-exchange resin that combines with described iodine.The polyvinyl resin that exudative Plastic Resin is habitually practised from the cost aspect is favored, and wherein exudative higher new LDPE (film grade) is because its melting point is low, be difficult for making iodine to receive an acclaim in conjunction with Yin Li Jiao Change resin thermal change.
Bactericidal plastic particle of the present invention, it comprises: exudative Plastic Resin, the Powdered iodine with sterilizing function and the Yin Li Jiao Change resin that combines with described iodine.
The present invention also can contain Yan material and dispersion agent or other plastics additives.
Will be inorganic being not easy dispersive in the liquid, solid particulate homodisperse such as organic raw material are for doing the 3rd composition that steady suspension is added.The interfacial agent that has the opposite nature that contains intramolecular hydrophobic group and hydrophilic group in the dispersion agent.Interfacial agent has the water-soluble character of composition that wet goods is not easy to be dissolved in water.
The working method of bactericidal plastic particle of the present invention is characterized in exudative Plastic Resin, the Powdered iodine with sterilizing function and the anionite-exchange resin that combines with described iodine are processed into the sterilization particle.
The present invention also can be processed into the sterilization particle with exudative Plastic Resin, the Powdered iodine with sterilizing function, the Yin Li Jiao Change resin that combines with described iodine and pigment and dispersion agent or other plastics additives.
Sterilization particle of the present invention can be sphere.Each sterilizing ability of deciding weight of described sterilization particle equates.
The present invention is in only limiting to the sterilization zone of water system, bring into play high efficiency sterilization effect in order to make most particles, by coating of particles is become sphere, make the less traction of particle surface, do not stop simultaneously the mutual suspension of most particles, each particulate mobile range is enlarged, can bring into play the sterilizing ability that each particle has to greatest extent.
The present invention further wants to make to be processed into the content of pulverous iodine in conjunction with anionite-exchange resin by increase and decrease, makes being in proportion of spherical bactericidal plastic particle, makes each sterilizing ability of deciding weight of particulate equate to be the bactericidal plastic particle of feature.
Compare the total surface area (total number of particles of particle swarm and 1 numerical value that the particulate surface-area multiplies each other) of 2 kinds of particle swarms of the identical weight that constitutes by the particle that differs in size, inversely proportional according to size and 2 kinds of particulate diameter of spheroid De Quality, total surface area.Because particle surface balancedly is scattered here and there and is processed into pulverous Dian Knot and closes anionite-exchange resin, if content is identical, the big more sterilizing ability of total surface area is strong more.That is to say that compare identical weight, the size 2 class particle swarms of same amount, small sized particles group's a side, because total surface area increases, sterilizing ability also increases.On the other hand, increase by 1 times of particulate diameter, if in order to keep equal sterilizing ability, when not being processed into pulverous iodine combination because of ion exchange resin content exponentially, its sterilization effect just can not be identical.
This thing is told us a reason: the diameter by adjusting spherical bactericidal plastic particle and be processed into the content of pulverous iodine in conjunction with anionite-exchange resin, the sterilization effect of the least cost that can provide conforms changes.
That is to say, even, also can bring into play equal sterilization effect with a spot of particle at the narrow space that the restriction of particle place is set; And during the occasion of using in the mobile water system, by increasing the particulate size, the space between each particle will become greatly, can not overslaugh current and reach germ-resistant purpose.
The present invention is processed into pulverously to have that sterilization effect De Dian Knot closes anionite-exchange resin and the bactericidal plastic particle made in exudative Plastic Resin.Bacteriums such as the bathtub of daily life, wash place, washing implement, water port easily under the water system environment of breeding, by the packing of wrapping material such as deodorization cloth and net box, can kill the bacterium of the water system that contacts with particle effectively.In addition, coating of particles is made sphere,, do not reduce effect by regulating the particulate size and being processed into the content of pulverous iodine in conjunction with anionite-exchange resin, do not increase above the particulate usage quantity that needs, just can bring into play effective germicidal action along with environment change.Promptly by this invention, can provide the bactericidal plastic particle of bringing into play longer duration, harmless sterilization effect along with the variation of water system environment and bacterium amount for the first time.
The sterilization particle of this invention in exudative Plastic Resin, contains at least and has been processed into pulverous iodine in conjunction with anionite-exchange resin, also can contain other plastics additives such as pigment and dispersion agent.
In exudative Plastic Resin, polyvinyl resin preferably, the low exudative higher new LDPE (film grade) of melting point wherein is owing to can not make iodine hand over Change resin thermal change reduction sterilization effect to gain great popularity in conjunction with the moon from son.
The sterilization coating of particles preferably can make the particle surface less traction, does not stop the mutual suspension between most particles, in the sterilization zone of being limit, enlarges each particulate moving range, brings into play the sphere of all sterilizing abilities of each particle to greatest extent.
Spherical sterilization particulate is big or small and be processed into pulverous iodine in conjunction with the content of the moon from son friendship Change resin, and under normally used situation, preferably diameter is greatly about 3～6mm, and content is greatly about about 10%.Wrapping material preferably have the cloth of deodorization effect and net box etc.In the mobile water system is used, in order not hinder current, preferably granular size is at the about 6～12mm of diameter, content about 20%.
