How to understand the universal workability of glue formulation design applications.

As a building decoration glue technology research and development exploration enthusiasts, has been, I for the current domestic large and small glue enterprise formula design applications exist in the generality is not strong or is not universal, etc. , this issue in recent years I have invested a lot of time and energy to visit all parts of the country to conduct research and Explore, and collected all over the country building decoration glue market application of the actual performance characteristics and status quo, after many years, many parties, many experiments and observations after the general conclusion is as follows:
on the building decoration glue (commonly known as: 107/108 /801/901, etc.) product end application construction process process it can only be regarded as "glue putty" in the A part, B part is all over the country ore powder fillers (such as: talcum powder, heavy calcium powder, light calcium powder and ordinary stone powder, etc.) and inorder gel materials such as synthetic (e.g. label cement, calcium powder, gypsum powder, etc.); This brings a difficult problem to the matching between building glue and B component filler, which is mainly reflected in the poor compatibility between A component (glue) and B component (filler) when ticking the use, reaction, state back to coarse "tofu slag", Paste body non-stick, paste under the spread hanging (the more stirring the thinner), false plasticity is poor, no tentacles, post-thickening, batch scraping effort, lighting roll skin, second-time drying, poor filling and so on series of issues, Usually the regional glue enterprises are basically based on the region's commonly used mineral powder filler chemical characteristics after a long period of exploration to improve the match between the enterprise glue and the region's commonly used fillers, found the best balance point and functional matching materials, so, for the most part, local glue matching Local commonly used mineral powder fillers basically do not have too many prominent problems, if the local commonly used mineral powders stop production, from the field to transport mineral powder fillers to match the glue of local enterprises, this time often all kinds of unexpected problems will be highlighted, or in other words, When the local glue transport to the outer region to hook up the mineral powder application of the outer region, all kinds of problems will be highlighted, this is what I mentioned above the regional mineral powder there are different standards containing mineral elements caused by the A, B composition matching when the phenomenon of matching, local enterprise technical personnel often in the field is not commonly used powder filler matching on the top, because upstream raw materials are difficult to grasp downstream, upstream materials are difficult to understand the academic So even if you have mastered some of the elements in the upstream material parameters, you may not understand which element of it and which element of glue is not compatible, even if you study which element of powder and glue which element is not compatible you do not have a good way to improve, because powder is not your production, its various elements are stereotyped, you can not change the powder anything, you only want to break through is to improve how your glue to match his powder, such problems often make many enterprise technicians can not break through for many years.
A high-quality glue products need to reflect the four basic performance are:
first, fastness, both with the main construction substation has a high adhesion and hardness;
With these four basic performance of glue in this person's cognitive conclusion is a good general purpose of the product, but the actual current situation is no enterprise glue can be used throughout the country, are in various regions according to the region's commonly used powder characteristics according to local conditions in the design formula, which also shows that a fixed glue formula can only adapt to local applications and can not achieve national generalization; As far as you say it is in the clouds, my glue painters say it's very useful, yes, if you question me like this I agree, but look at the official ah! Please look carefully and then make your remarks not too late, I am talking about the generality refers to the same glue products can adapt to powder applications throughout the country, I hope you can raise their height, you will see the best scenery

. Here I would also like to give an example, for example: some batch of glue scraping heavy calcium, talcum powder, gypsum powder are very good, bonding gypsum line solidification time is also good, but is the batch scraping label white cement twice to grab dry; One example, another example is another glue batch scraping local any powder is very good batch scraping is bonded gypsum lines can not, because the dry too slow, lines can not be stained, similar examples too many, in this one is not listed.
After many years, many parties, many experimental observations, I on the glue universal formula design concept is:
polyethylene alcohol as the main adhesive material, to environmentally friendly aldehyde-free non-toxic "aldehyde energy clean" instead of environmentally friendly methyl Aldehyde as a polyethylene alcohol glue system trigger polymer, supplemented by a small amount of polyacrylamide as a thickening and improve the construction scraping, this formula is not recommended to intervene in acrylamide and cellulose materials, because acrylamide paste plaster line dry No, cellulose in the polyethylene alcohol system will be layered, so the intervention of these two materials will not achieve the purpose of universality; Ethylene alcohol content, supplemented by appropriate thickeners and smoothing agents to improve construction performance, the above two schemes are more general than ideal, after polymerization reaction of polyethylene alcohol glue antifreeze melt is better than non-polymerized polyethylene alcohol glue, That is, the second option in the winter temperature of low areas to appropriately add antifreeze, otherwise because the temperature is below 0 degrees when the glue is prone to flocculation reaction.
above is that I have made a conceptual analysis of the generality of glue, then what is the workability?
We do research and development or do technology often hear someone say to you, where he got a formula, go back to make the glue is always not ideal state, always feel the formula is still owed something, always feel the performance is almost fire, but do not know what is missing; It's not very good, so when you get his formula you are not in the same province and region, this time A, B components of the problem of matching differentiation is highlighted, but his formula in his local application of outstanding problems is not so obvious (except for the formula without technical content), which fully illustrates the large frame structure of glue formula across the country is basically similar, change is not far from its original, the core technology is a formula in different provinces (regions) when you have to understand what to avoid, increase what, adjust what, This is called technical workability.
see here, one of the things that people are most interested in is how to work around it?
"workable" word is simple to say, but it is not easy to do, first of all you have to understand the performance and function of various materials in glue, and then you also need to understand the construction performance of glue, to understand from the state of analysis of the problem, that is, through glue and powder hook After the state of what phenomenon, or scraping when there is any phenomenon, according to the phenomenon to judge what to add or subtract what to improve, such as: Zhejiang individual areas of the powder hook glue after no degeneration, paste under the stall, false plasticity poor, this state is not conducive to the smoothness of construction and protection Water-like, batch scraping twice when the water is not enough, easy to grab dry and roll skin; Increased", because the paste absorption rate increased, water preservation on the increase, chain problems have been improved, of course, this example is only the tip of the iceberg in the "workarient" technology, there are count of "workarient" technology, Because it is not three words and two words can express comprehensive, so this article is parsed to this, there is a need for deeper communication please add me 15093099808 (telephone with WeChat).
Since the release of this post, just a few days received from all parts of the country's hardcore netizens private letter, most netizens in the private letter unanimously reflected want to see more areas of different powder and glue matching technology workarient cases, in order to better meet the wishes and suggestions put forward by hardcore netizens, I make the following supplementary cases on this related issues as follows:
1, for example, Sichuan Jiang oil city powder and glue hook, batch scraping in the wall, The thinner the scrape, can not play a thick batch effect and fill the pit, this phenomenon is mainly caused by different powder characteristics, improvement methods: the use of anti-flow thickener can be perfectly improved.
2, for example, Zhejiang Lishui has a kind of white cement, hook glue thickening serious, a bucket of stirred good material, scrape less than half of the remaining half of the barrel will be re-glued into the stirring can continue construction, improve the method: the use of glue-specific modifiers in the glue production process to add finished glue mixed evenly.
Three, such as Fujian Zhangzhou, Xiamen Tong'an District, a stone powder, and glue hook mixing, construction less than half of the rise, it seems that the water is consumed, the state is back thick, scraping the skin to dry, feel heavy, difficult to collect light and other phenomena, improvement methods: no matter what system of glue formula, in the production process to add glue-specific meso-agent can be perfectly improved.
4, for example, Henan Puyang area has a private compound of white cement, and glue hook, the first batch scraping normal without any abnormality, when scraping the second time, the wall is dry, simply can not be normal construction, improvement methods: completely improve the glue ratio, must be based on acrylamide co-polygluor water, appropriately improve the glue solid content, replaced with glue-specific thickeners can be perfectly improved.
5, for example, a white cement in Taizhou, Zhejiang Province, and glue hook after the first good batch scraping, the second time on the wall to grab dry, improve the method: acrylamide co-polygel water-based, in the glue production process, the use of a normal temperature crosslinker, first a small number of raw glue with normal temperature crosslinking agent after the backup, and then in each ton of finished glue dilution to add 1 kg of cross-linking good spare raw glue can be perfectly mixed.
, most of the glue in other parts of the country applicable to glue smoothing agent, in the glue production process involved in the smoothing agent can be basically perfectly improved.
