Abstract
Use is piled the method and composition of sheet glass stain with the periporate powder cushioning material of strong organic acid dipping to reduce buttress.
Description
The present invention is about preventing to pack the technology that sheet glass pollutes, particularly about handle the technology of sheet glass with Powdered cushioning material in general.
United States Patent (USP) the 3rd, 723, in No. 312, Hay has disclosed the glass plate packing method with the mixture separation of the inertia separation material of the sintering Whitfield's ointment of free from dust and a kind of as polystyrene spheres.
In No. the 4011359th, the United States Patent (USP), a kind of liner material of separating sheet glass of disclosures such as Simpkin is to form with the porous of dipping weak acid (as hexanodioic acid) superfine carrier and the big slightly chemically stable plastics (as methyl methacrylate) of particle.
In No. the 4200670th, the United States Patent (USP), Albach has narrated a kind of method of handling the sheet glass of buttress heap, i.e. water and a kind of antipollution material (for example ammonium chloride) and a kind of mechanical separation (for example wood powder) processed in sequence.
By the United States Patent (USP) that be entitled as " reduce glass surface reactive organotin handle " of Helmut Franz in submission on October 9th, 1979, application serial 83084, revealed the chemisorption of organo-tin compound, tin functional group is bonded to glass and organic moiety stretches to that glass is outer to obtain a low-energy surface layer.
The present invention includes a kind of Powdered liner material of having improved and be used to stop the sheet glass of packing to produce stain, comprise the strong acidic organic compound of a kind of usefulness impregnated porous carrier material in small, broken bits (as wood powder).
According to the present invention, a kind of vesicular carrier material in small, broken bits is with strong organic acid dipping, and conventional porous prilled liner material is preferably with water-soluble and be the processing of solid strong organic acid at normal temperatures.
Though also can use the high poly-carrier material of inertia and other inorganic particulate matter such as vermiculite, best vesicular carrier material is cellulosic material (as the Exocarpium cocois (Cocos nucifera L) and the wood powder of ground rice, grinding), preferably common hardwood flour cushioning material.
The used strong organic acid of the present invention will have following characteristics: when they are water-soluble with about 1% weight concentration, its pH is less than 3, best strong organic acid has citric acid, propanedioic acid and tartrate, good especially organic acid is the water miscible organo-tin compound of strong acid, especially the fontanelle compound of organotin, particularly the pH of its 1% aqueous solution is less than 2.5 organic acid, comprise the tin alkyl fontanelle compound, methyl tin chloride particularly, methyl tin chloride for example, dichloride tin methide, and their mixture, their pH is generally less than 2.
Most preferred embodiment of the present invention is to handle with best aqueous solutions of organic acids and carry out drying with a kind of porous particle cushioning material of routine.The cushioning material of acid dipping can be distributed between the sheet glass of desire buttress heap with any routine techniques.For example the wadding with acid treatment can scatter glass surface with the equipment of routine.Yet in the embodiment an of the best, the Powdered backing of acidifying is applied on the glass surface with pulpous state, this method such as inventor serve as the United States Patent (USP) (application serial 229 that topic is submitted to same date with " to the method for sheet glass coated liner thing ", 220) described in, can be as a reference at this.This coating technique makes cushioning material be adsorbed in glass surface more tightly; thereby the loss of minimizing cushioning material and the ununiformity of distribution; this situation is typical in the process of handling sheet glass; according to the present invention; being used to handle the alkalescence that the strongly-acid organic compound of cushioning material can neutralize between the buttress heap glass effectively focuses on; improve protection, prevented pollution.
In a best embodiment of the present invention, the wood powder cushioning material is to handle with a kind of aqueous solution of tin alkyl fontanelle compound.The wood powder cushioning material of routine is dispersed in the aqueous solution of methyl tin chloride, (is typically several minutes) in the time of a fixed length, make methyl tin chloride acidifying wood powder, the wood powder of acid dipping can filter and be dry, or convection drying.This depends on the concentration and the volume of methyl solution of tin, and acid treatment and drying can realize under normal temperature or heating condition.
The present invention can further be understood from following object lesson.
Example 1
The wood powder backing with contain the 1%(weight percent) aqueous solution of methyl tin chloride contacts, wood powder is 40～80 purpose hardwood products, International Filler Corporation provides by New York.Methyl tin chloride contains the dichloride tin methide of 80% weight and the methyl tin chloride of 20% weight, provide with 50% aqueous solution form by the Carstab Corporation of Reading of Russia's last of the twelve Earthly Branches thirty, wood powder is immersed in the acidic solution 5-10 minute, dry at normal temperatures then, the methyl chloride solution of tin is highly acid, pH is 1.45, and the wood powder of acid dipping is applied to glass pane surface with common powder coated device with the spraying technology of routine.The glass straight sheet pile of handling is banked out, and be exposed under the temperature that relative humidity is 100% and 140 (about 60 ℃), check antipollution situation.The buttress heap sheet glass of separating with untreated wood powder backing only just produced stain in 7 days, and did not produce stain at least in 14 days by the buttress heap sheet glass that the wood powder that this example was handled with methyl tin chloride is separated.
Last example explanation can improve anti-soil spot performance by the present invention, other changes of this invention, for example use other strong acid organic substances, some other cushioning material and different concentration and amounts all comprise within the scope of the invention, and these changes are determined it by following claim.
