Abstract
The invention relates to a PET bottle chip recycling treatment rinsing agent. The PET bottle chip recycling treatment rinsing agent is formed by mixing raw materials of, in part by weight, 10-40 of compound surfactant, 1-20 of adjuvant, 1-15 of chelating agent and 25-85 of pure water, wherein the compound surfactant is the compound of a polyether surfactant and a sulfo surfactant. Compared with the prior art, the rinsing agent uses the compound surfactant for reducing the surface tension between rinse water and PET bottle chips, accelerating flocculating of residual chemical substances of the PET bottle chips and achieving good drying effects in a subsequent dewatering and drying step and uses the adjuvant for adjusting the water and assisting in the playing of the effect of the surfactant for further enabling substances in the rinse water to be not prone to re-attaching to the PET surface. Therefore, the water content can be reduced by 0.2% to 0.6% after mechanical dewatering and the water consumption per ton of PET chips can be reduced to 2 cubic meters-2.5 cubic meters.
Description
Technical field
The present invention relates to a kind of purificant, especially relate to a kind of PET bottle sheet recycling process purificant.
Background technology
The cleaning of recycling PET bottle or other plastics is the wash characteristics belonging to " crust ", and in the process of cleaning, rinsing process often water loss is maximum.Residual in order to what reach on rinse PET bottle sheet completely, in traditional technology, bottle sheet per ton needs water consumption 4 ~ 6M
3.The large factor of rinse water consumption is except the objective condition that apparatus and process designs, and the water quality impact that PET bottle sheet itself has fine surface pore and rinse water causes the principal element of not easily rinse especially.
If rinsing can not be thorough, except the chemical residue in pore cannot be removed, the inorganic salts that may exist in rinse water also can be attached to pet sheet face, thus has influence on the quality of regenerative PET bottle sheet.
Under the background of an above-mentioned existing difficult problem, domestic even external existing correlation technique all cannot with comprehensively, effectively and meet environmental protection, the method for economic principle reaches the object of dealing with problems.
Summary of the invention
Object of the present invention is exactly the PET bottle sheet recycling process purificant providing a kind of to overcome defect that above-mentioned prior art exists and accelerate wash effect, remove residuals, reduce rinsing water consumption.
Object of the present invention can be achieved through the following technical solutions:
A kind of PET bottle sheet recycling process purificant, is mixed by the raw material of following component and weight part:
As preferably, described purificant is mixed by the raw material of following component and weight part:
Described compound surfactant is selected from the composite of polyether surfactant and sulfo group class tensio-active agent, and the composite weight ratio of polyether surfactant and sulfo group class tensio-active agent is 4:1-1:4.
As preferably, described polyether surfactant comprises AESA, polyoxyethylenated alcohol sodium sulfate, alkylpolyoxyethylene sulfuric acid trolamine, ethoxylated dodecyl alcohol sulfosuccinic acid monoesters disodium, block polyether phosphoric acid ester, ethylene/propene block polyether, fatty alcohol-polyoxyethylene ether methyl-monosilane, polyoxyethylene glycerol ether monostearate or castor oil polyoxyethylene ether;
Sulfo group class tensio-active agent comprises hexadecyl diphenyloxide sodium monosulfate, aerosol-OT salt, α-semi-annular jade pendant base succinate or N-methyl oil amido ethylsulfonic acid sodium.
Described assistant agent is one or more in Trisodium Citrate, sodium oxalate or thionamic acid.
Described sequestrant is disodium edta, instant Starso or sodium polyacrylate.
Described purificant is liquor, is useful in the final rinse stage of PET fragment.During use, after diluting 50 times with water, quantitatively add with rinsing water 1 ‰.
Compared with prior art, the present invention has the following advantages and beneficial effect:
Final rinse stage due to PET fragment by washing composition dilution residual for washes and then need remove, and makes it to reduce the residual of washing composition as far as possible.Under general condition, rinsing PET bottle sheet to lotion to remain conformance with standard (<50ppm), depending on using the condition of washing composition, general PET fragment per ton must water consumption 4 ~ 6M
3.Add that each region uses water quality diversity factor large, with the organism or the inorganics that contain higher concentration in water, therefore the possibility of PET bottle sheet by rinse water secondary pollution easily occurs.
And in purificant of the present invention, adopt compound surfactant, can accelerate wads a quilt with cotton with PET bottle sheet residual chemicals closes, and other assistant agents, as the adjustment of water quality, make the material in rinse water not easily again be attached to pet sheet face.Under this effect, rinsing water can be made to be reduced to PET fragment water consumption per ton 2 ~ 2.5M
