Abstract
The invention discloses a plastic cleaning method, belongs to the technical field of plastic cleaning, and aims to provide the method which is simple to operate and capable of effectively removing stains adhered to plastic. The method sequentially comprises the steps as follows: 1) evenly mixing 1 part of a plastic cleaning agent by weight and 10-15 parts of water by weight to obtain a mixed cleaning fluid; 2) soaking to-be-cleaned plastic in the mixed cleaning fluid obtained in the Step 1) at the temperature of 30-40 DEG C for 1-3 min; 3) washing the plastic clean with water.
Description
Technical field
The present invention relates to a kind of metallo-plastic cleaning agent method, specifically, relate to a kind of method of cleaning plastics, belong to plastic cleaning technical field.
Background technology
Along with plastic products consumption figure constantly increases, waste plastic is on the increase.China's waste plastic is mainly plastic sheeting, plastic knitting product, foamed plastics, plastic package box, plastic bottle, plastic containers, polybag and agricultural mulching etc.If the depositing of these waste plastics, transport, processing and post-processed improper, will certainly welding, the harm common people are healthy.
At present, the market value of China's waste plastic application is to reach more than 1,000 hundred million yuan.Along with the rise in price of plastic raw materials, waste plastic market has been produced to great impetus, waste plastic price also sharp rises, its approached and do not risen before the price of raw material.
The removal process of waste or used plastics mainly comprises that cleaning, pulverizing, granulation, reprocessing utilize four steps.Wherein, cleaning is primary link, does not clean direct pulverizing, granulation, and the product colour of making, quality, fineness are all poor, and applicable scope is little, and added value of product is low, is unfavorable for the development of technics of reclaim of plastic waste industry.The stain of existing waste or used plastics mainly take that vegetable and animals oils, mineral greasy dirt, printing-ink, chemical industry are residual, sugar, mineral precipitation, rust staining, packing material are residual, adhesive sticker etc. is as main, and cleaning process take that to use cleaning agent to clean be Main Means.
Plastic cleaning agent is a kind of solvent that frosting cleans that is specifically designed to, in it is widely used in that plastics recovery processes early stage cleaning process.Conventionally high osmosis auxiliary agent and kinds of surface activating agent, consisting of, is a kind of aqueous cleaning agent, can to frosting, clean fast and effectively, makes it reach the requirement of later stage recycling.
Existing plastic cleaning agent performance is improved, improved the cleaning quality of plastic cleaning agent, guarantee cleaning speed, realize extensive, sustainable suitability for industrialized production, just become matter of utmost importance to be solved by this invention.
Summary of the invention
For the problems referred to above, the object of the present invention is to provide a kind of simple to operately, can effectively remove the method that adheres to spot on plastics.
For this reason, technical scheme provided by the invention is such: the method comprises the steps: successively
1) 1 weight portion plastic cleaning agent and 10-15 weight parts water are mixed, obtain mixing cleaning fluid;
2) need to clean plastics and be immersed in 30-40 ℃ step 1) in mixing cleaning fluid in 1-3min;
3) with clear water, rinsing well;
Wherein:
Step 1) every liter of described plastic cleaning agent consists of following component: NPE 100-200g, oxalic acid 60-80g, AEO 5-10g, APES 1-5g, thiocarbamide 3-7g, propylene glycol monomethyl ether 20-50g, disodium ethylene diamine tetraacetate 5-10g, pentyl acetate 10-20g, surplus is water.
Further, the method of above-mentioned cleaning plastics, every liter of plastic cleaning agent contains following component: NPE 120-180g, oxalic acid 65-75g, AEO 7-9g, APES 2-4g, thiocarbamide 4-6g, propylene glycol monomethyl ether 30-40g, disodium ethylene diamine tetraacetate 7-9g, pentyl acetate 12-18g, surplus is water
Compared with prior art, technical scheme tool provided by the invention has the following advantages:
Overall evaluation of a technical project strong detergency provided by the invention, can effectively remove the spot adhering on plastics, and after rinsing, plastics are clean as new, reduce pollution emissions, and clean with low cost; Can use by large-scale industrial production efficient, environmental protection.
