Abstract
The invention provides a soaking solution for stripping a paper bag film, which consists of the following components in parts by weight: 5-15 parts of inorganic base, 5-15 parts of alcohol, 1-6 parts of anionic surfactant, 1-6 parts of nonionic surfactant, 0.05-0.1 part of heavy calcium carbonate and 250-500 parts of water. The paper bag soaked by the soaking solution has the advantages that the paper material can be quickly peeled from the film, and the recycling of the paper material is further realized.
Description
Technical Field
The invention relates to the technical field of cleaning and recycling paper products, in particular to a soaking solution for stripping a paper bag film.
Background
The calcium silicate board is made up by using loose short fibre of inorganic mineral fibre or cellulose fibre as reinforcing material and using siliceous-calcareous material as main body cementing material through the processes of pulping, forming and curing reaction in high-temp. high-pressure saturated steam to form calcium silicate gel body. The calcium silicate board is one of the most advanced cavity wall materials at present, and has the advantages of water resistance and moisture resistance. The composite board has the advantages of durability, low deformation rate, heat insulation and the like, and is particularly suitable for being used as a wallboard and a ceiling board in the interior of a building.
The calcium silicate board is made of silicon material (SiO as main component)2For example, quartz powder, granite, diatomaceous earth, etc.), calcareous material (the main component is CaO, such as lime, calcium carbide mud, cement, etc.), reinforcing fiber material, auxiliary agent, etc. are mixed according to a certain proportion, and the new inorganic building material is made through the processes of copying or mould pressing, steam pressure curing, etc., wherein the reinforcing fiber material includes paper pulp, but if the cost of directly purchasing the paper pulp is higher, if the paper material in the waste paper bag can be recycled, the cost of the calcium silicate board can be greatly reduced.
Disclosure of Invention
The invention provides a soaking solution for stripping a paper bag film, wherein a paper material of a paper bag soaked by the soaking solution can be quickly stripped from the film, so that the paper material is recycled.
In order to achieve the purpose, the technical scheme of the invention is as follows:
a soaking solution for stripping a paper bag film comprises the following components in parts by weight: 5-15 parts of inorganic base, 5-15 parts of alcohol, 1-6 parts of anionic surfactant, 1-6 parts of nonionic surfactant, 0.05-0.1 part of heavy calcium carbonate and 250-500 parts of water.
Preferably, the soaking solution for peeling the paper bag film consists of the following components in parts by weight: 8-12 parts of inorganic base, 6-12 parts of alcohol, 3-5 parts of anionic surfactant, 3-5 parts of nonionic surfactant, 0.06-0.1 part of heavy calcium carbonate and 300-450 parts of water.
More preferably, the soaking solution for peeling the paper bag film is composed of the following components in parts by weight: 10 parts of inorganic base, 9 parts of alcohol, 4 parts of anionic surfactant, 4 parts of nonionic surfactant, 0.08 part of ground calcium carbonate and 395 parts of water.
Further, the inorganic base is one or more than two of sodium hydroxide, potassium hydroxide, sodium carbonate, sodium acetate and potassium bicarbonate.
Further, the alcohol is one or two of ethanol and isopropanol.
Further, the anionic surfactant is one or two of dodecyl benzene sulfonic acid, fatty alcohol acyl sodium sulfate, ethoxylated fatty acid methyl ester sodium sulfonate and secondary alkyl sodium sulfonate.
Further, the nonionic surfactant is one or two of fatty alcohol polyoxyethylene ether, lauryl alcohol polyoxyethylene ether and octanol polyoxyethylene ether.
The soaking solution for stripping the paper bag film has the following advantages:
(1) the film can be assisted to be quickly separated from the paper material through the action of alkali;
(2) the liquid can be accelerated to permeate between the paper material and the film under the action of the alcohol, the anionic surfactant and the nonionic surfactant, so that the film can be quickly peeled;
(3) through the friction effect of the heavy calcium carbonate, the generation of bonding dead angles can be avoided, and the complete stripping of the film is ensured.
(4) The soaking solution can help to realize the quick recovery of paper materials and reduce the production cost of the calcium silicate board.
(5) The soaking solution adopts nontoxic and harmless substances, and the recycled paper material is used for producing the calcium silicate board without generating negative influence on human health.
