8、urce: adhesive project group release time: 2010-4-23 11:36:17, click: 477Recently, my companys customers at home and abroad for the Teflon material and other materials (including materials) specific operating methods, requirements, we hereby give more detailed instructions.1, first of all, PTFE mate
9、rial around 200 mesh sandpaper, evenly polished clockwise and negative surface.2, then the PTFE material processing professional agent into a metal container, the amount of volume or quality of the PTFE material slow delivery to the processing agent, and stirring treatment agent to avoid treatment a
10、gent at the same time to cover layered container to avoid volatilization treatment agent. The treated agent shall not be poured into the unused treatment fluid.3, at room temperature for 5-15 minutes after the invasion, can clearly see the surface color is black or blue PTFE can remove PTFE material
11、, remove the lid after treatment agent used to prevent volatilization, and will deal with the surface of PTFE material cleaning with distilled water or cold water, the surface of the material has been cleaned aerosols.4. Clean the PTFE material into the oven or the electric hair dryer to dry its sur
12、face, until the surface is completely dry.5, to its PTFE material surface drying, and then dipped in a little PTFE material, surface cleaning agent B in PTFE material surface repeatedly wipe several times, and then it will blow or oven drying PTFE surface.6, the surface of the drying material evenly
13、 thin scrape coated with a dedicated glue, glue layer thickness in both sides, the total thickness of about 0.15mm. Then the stainless steel material to give fair 2 proper external force pressing and clamping, can be heat curing. Can be synchronized heating up heating, curing, so that the glue curin
14、g more thoroughly, strength and other performance more remarkable.7, if the PTFE material and hard metal and other metal bonding, then the need for metal surface sand or acid treatment. The treated metal surface is wiped several times with the material treating agent B. Then, drying the metal surfac
15、e, and finally in the glue evenly and evenly scraped on both sides of the PTFE and metal, the total thickness of the glue layer is about 0.15mm. Then in a same level with PTFE surface or in a plane rigid material compaction, pressure to achieve a small amount of glue overflow is good.Technical speci
16、fication for laminated glass processingSource: Company adhesives project group release time: 2007-7-10 22:08:27, click: 2035Common problemLaminated glass glue matters should be paid attention to in the doubling operation time:1. This product shall be made of fresh float glass. The sealing strip shal
17、l be made of PUB film or laminated glass glue sealant produced by our factory.2, try to expel bubbles, especially the micro bubbles at the edge of the sealing strip. If the bubbles are not discharged, they can be immediately added or pumped.3, when the temperature is higher (higher than 30 DEG C), s
18、hould not be too long in the sun exposure time (less than 90 minutes), in case the reaction is too intense and tear glass.4, glue should be avoided in the shade and ventilated place to save.5. The cleaned surface should be dry after washing6, the bonding medium may not be mildew and metamorphism7, t
19、he bonded medium can not be weathered;8, air humidity is relatively large, not in advance of the glass clip, put aside, then the interface of the interlayer inside into the water vapor;9, can not be mixed with water or glue other substances appeared in the fog and air bubbles10. Do not mix this glue
20、 with any other glue;11, the use of non glue tools mixed use;12, the vicinity of the processing plant can not have large sulfide and other chemical enterprises;13, the operation must be discharged air;14, fog weather will also be in the glass interlayer in the presence of a large number of water vap
21、or, it is necessary to be cautious15, tempered glass itself flatness is not enough, the glue can not be saturated and degumming phenomenon (the glass itself caused by tension);16, edge banding tape does not match the use of other edge banding tape;17, the saturation of the gel should be a suitable a
22、mount.18, silk, silk, paper, plants and other materials must be dry, can not be water, and can not blackWhy does the laminated glass glue appear after curing?:Air humidity is relatively large, not in advance of the glass clip, put aside, then the interface into the inside of the water vapor;Not in t
23、he inside glue blending water or other substances, appeared in the bubbleHeavy fog also causes a great deal of water vapor in the interlayer of glassThe methyl ester content is too lowThe content of the inhibitor in the methyl ester is too highTempered glass itself is not smooth enoughOperating time
24、, air bubbles are not completely dischargedLaminated glass, wired glass edge sealing operation is not goodNote: 1, if you need to consider the double tempered laminated toughened glass itself such as smoothness, flatness is not ideal, you can use PVB glue for sealing the first seal gap between the g
25、lass (too much space and then use the transparent silicone rubber seal). This process operates the production of ice breaking glass.2, if the use of adhesive tape to seal the glass, you need to pay attention to the following itemsA, glass clean natural drying, the first piece and then use the transp
26、arent tape attached to the glass clean, first section, and then the glass plane fitting, to prevent air residual effects of middle (anaerobic) curing glue.B, if you are using PVB strip produced by our company is sealed, sealed in time need to pay attention to fully fit the rubber strip and the edge
27、of the glass, if the glass itself is not smooth or glue can not be completely fit to use silicone rubber to supplement (also need to be fully cured silicone rubber sealing glue for irrigation) to correct dont avoid edge, curing or curing time is long.Laminated glass degumming:The methyl ester conten
28、t is low, or the ratio of the methyl ester in the glue is too littleThe glue formulation technique was prematureExcessive butyl esterLaminated glass glue yellowing phenomenon:In the production of glue at the time, the proportion of acid plus too muchThere is a lack of glue synthesis technologySugges
29、tions and suggestions on the treatment of metal interface during the use of metal heat resistant adhesiveSource: Company adhesives project group release time: 2007-10-6 20:35:32, click: 909At present, a lot of customers in the bonding of metals and metals, and metals and other materials, the surface
30、 treatment recommendations;1, if the metal is Aluminum Alloy in general can be directly to the 37% concentration of hydrochloric acid treatment can also pay attention to the size and concentration of hydrochloric acid in the safe operation in the process of acid pickling to avoid splashing out to bu
31、rn the skin, if this happens quickly please wash the skin with cold water, and please the process in the ventilation dry place.2, if the metal component requirements are not very fine, you can directly use 20 purpose sandpaper surface treatment3, if the metal is copper can use hydrochloric acid (HCL
32、) (37% concentration), remember not with sulfuric acid (H2SO4) sulfate because the water will spill wounding, metal parts is fine and then rinse with water after the dry sizing. At the same time to stay away from the fireworks and the ventilated and dry environment of pickling.4, if the metal parts
33、and other composite materials link, it is best to the two interface in cleaning, then the bonding effect will be better5, if encountered ABS similar composite, ABS surface must be cleaned out rough, so the bonding effect will be better6, if the metal surface and silicone rubber bonding, then two sur
34、faces are required to deal with, while the silicone rubber surface must be carried out grinding process (metal surface treatment, such as the above method)7. If the metal that needs to be bonded is electroplated metal, the plating layer of the bonding part should be treated,Because the plating layer
35、 intensity is very small (0.20.7KN / CM2) will affect the bonding parts of the tensile and shear strength.It used to be some common treatment:Commonly used surface treatment methods, surface treatment methods are many, the following are introduced:A. alkali paint stripping, aluminum alloy parts, you
36、 can use the following formula:Phosphoric acid, three sodium, -25 sodium silicate, -12 soap, -3, acid, potassium, -3, water, -1800Boil the solution for 27 hours, then rinse and dry.Solvent stripping, room temperature use, simple and convenient, but toxic and flammable. Recipe is as follows:Dichlorom
37、ethane -65 85 -1 6 -2 formic acid phenol - 3 ethanol -2 8 vinyl chloride resin -0.5 2 peregal -O 1 4The formula is suitable for amino, acrylic ester, phenol aldehyde, epoxy resin, polyurethane and so on.B. degreasing degreasing, solvent degreasing, lye degreasing, degreasing (chemical degreasing), e
38、lectrochemical degreasing. Among them, emulsion degreasing formula for-67 -23 -3.6 kerosene terpineol triethanolamine lauric acid -5.4 butyl cellosolve -1.5C. derusting, roughening, derusting, roughening methods are many, there are manual, mechanical and chemical methods. Manual method is simple, po
39、or labor conditions, low efficiency. Mechanical method mainly for sand blasting, convenient and efficient, easy to deformation objects, high elasticity objects are not applicable. The chemical method is the use of chemical methods to dissolve corrosion spalling of metal surface, especially suitable
40、for small and complex parts, and sandblasting equipment condition place.D. chemical treatment increases the bond strength by chemical treatment of the surface material of the glued material. Such as injection primer, surface treatment agent, coupling agent, surface and adhesive bonding, improve bond
41、 strength.Different material surface treatment methods are different, such as iron and steel surface, concentrated hydrochloric acid 1 parts, 1 parts of water, room temperature treatment 510 minutes, wash and dry. Copper and copper alloy surface, iron trichloride (42%) 5 parts, concentrated nitric a
42、cid 6 parts, water 40 parts, room temperature treatment for 510 minutes, washed and dried. Zinc and zinc alloy, concentrated hydrochloric acid 1 parts, 4 water, room temperature treatment for 24 minutes, washed and dried.Opinions and suggestions on storage methods of single component high temperatur
43、e glueSource: Company adhesives project group release time: 2007-10-6 20:55:35, click: 831Recently, many customers have shown that a single component high temperature adhesive is used in the process of increasing the viscosity of the glue. Here, we describe the storage method or skills of the single
44、 component high-temperature glue:The 1 single component high temperature glue in our technology has been doped with mixed amine curing agent, so we need to process stored at room temperature. We generally say that at room temperature refers to the temperature of 25 degrees Celsius, also need to seal
45、 the dry and ventilated environment.2 if it is to purchase large quantities of words or batch sizing, you need to put the glue stored in the freezer (temperature control in 5 degrees) so that the curing time of storage method can delay the glue is its life. Because the single component glue in the h
46、eat absorption process will receive the accumulation of heat and rapid response, so so.3, we are in the sizing process, in the choice of plastic containers, we can choose to open wider vessels, or glue the tiles and a flat surface,In this way, the glue will heat up very quickly, and it will also retard the embarrassment of the glue because of the rapid accumulation of heat and the waste of glue
