Below performance of the present invention is described further,
Water-based low irritant adhesive remover: a kind of glue removing composition agent, product adopt water-soluble system, can add water by concentration and regulate, and have the little characteristics of smell.Comprise that a certain proportion of AEO and multiple aqueous alcoholic and organic amine are separately or be composited.Product, mixes and stirs through batching through requiring operation with related process in proportion, thermal treatment, and sterilization and anticorrosion, operations such as discharging filling formation are processed, and in the plastics or vial of can safety and environmental protection, and join an applying glue mouth.
Product cooperates rationally, contains a large amount of electrolytical salts, destroys the charge balance of system, can be with a part of organism cohesion, and the disengaging aqueous systems of saltouing plays destruction, cleaning easily for the tackiness agent of some organic molecule materials.And a large amount of amine materials makes that the infiltration wetting ability of this agent is fine, could be that the residual glue that need remove softens fast, and is loosening, comes off, and some sulfonamide derivativess have sequestering action simultaneously! Simultaneously organic amine has weakly alkaline, and good deoiling effect is arranged, and for some unsaturated polyester jointing materials two good destructions is arranged.Can ensure that again there is corrosion inhibition the metallic surface in the time of for the tackiness agent of process metal surfaces.For some carbohydrates and some organic binder bonds the good effect of peeling off is arranged,
Adopted polyoxyethylenated alcohol sodium sulfate and AEO silane at last,, the reasonable combination of TX10; Be main raw; Being equipped with the tensio-active agent of appropriate H LB value. this component tensio-active agent, HLB value preferably contain two nitrogen-atoms 1~7.9 in the molecule; And two primary amine of methylate Ethylene Oxide, oxyethane containing of getting or the organic amine of secondary amine group in order, carbonatoms is no more than 22.In prescription, the scope of the weight ratio of tensio-active agent and basic amine component is generally at 1: 26~1: 12.Being product all possesses good avidity for aqueous binder and the property said tackiness agent, can form the O/W oil-in-water system fast, goes out adhesive material.Fatty alcohol polyethenoxy ether class product pungency is low simultaneously, is not easy to cause discomfort! Product possesses dual washing decontamination simultaneously.Material can be directly goed deep in this agent, removes various residual stains rapidly.
Also have product of the present invention,
One, product cooperation aspect has been considered, soaks, and system is destroyed, gel, and the infiltration parcel such as peels off at a series of residual modes of removing, and has adopted inorganic salt, organic amine, and the proportioning that combines of multifunctional meter surface-active agent.Flexibility than traditional is strong, and specific aim is wide, organic to present employing, and inorganic combination adhesive could both adapt to!
Two, the water-based system of product employing is more stable than the oiliness system of traditional most of clean-out systems, safety, environmental protection! But system has adopted the organic amine with corrosion inhibition, is again that some traditional water-based adhesive removers are not available.
Three, the salt component and the tensio-active agent component that adopt, organic amine replaces ammoniacal liquor, reduces the bad smell that causes because of the ammoniacal liquor volatilization, and smell all reaches low, does not have pungency! From result of use, environmental requirement, personal feeling, the several aspects of Environmental Safety all are superior to conventional traditional glue cleaning material that removes just!
Other character: pH value is 7, is neutral, and is to most surfaces safety, effective especially, easy-to-use to there not being hardened glue.
Function: be used to remove other sticking thing primer that is coated with such as non-setting adhesive, self adhesive foil, double faced adhesive tape, adhesive tape and be detained glue stain or the glue dirt that the back forms, remove various trade mark adhesives fast.Elimination viscosity, degreasing remove glue, release to separate and adhere to oil stain.
Accommodation: suit to remove posters, subsides of carving characters, adhesive tape glue, fit up surplus glue, self-adhesive pad pasting, cuticula cull, ink paint, resin grease, pitch, machine oil, chewing gum, exhibition room identifies and floor dirt etc. can use on surfaces such as glass, pottery, marble, stainless steels.
Method of use: load onto the applying glue mouth, stoste spray or drip and be coated onto the surface.Treat after the several minutes dissolving deliquescing or let the adhesive remover infiltration, start bonding coat with hand then, peel off unnecessary obedient paper, can be at label, many a little solution below mark or the adhesive tape.At last with clean wet cloth scrub.For some unusual aged jellies, wiping or available brush are scrubbed once more.And product appearance had no to be influenced it and belongs to volatile matter.After the product appearance processing, have no smell, be difficult for the injury surface.
