The above three materials are introduced:
(1) super absorbent resin is a new functional polymer material. It has high water absorption function of absorbing water hundreds to thousands times heavier than itself, and excellent water retention performance. Once water is absorbed and swelled into hydrogel, it is difficult to separate water even under pressure. Therefore, it is widely used in personal hygiene products, industrial and agricultural production, civil construction and other fields.
(2) Sodium polyacrylate is a new functional polymer material and an important chemical product. The solid product is white (or light yellow) block or powder, and the liquid product is colorless (or light yellow) viscous liquid. Soluble in cold water, warm water, glycerin, propylene glycol and other media, it is stable to temperature change, has the function of fixing metal ions, and can prevent the negative influence of metal ions on products. It is a kind of surfactant with many special properties.
Polyacrylamide product introduction: Polyacrylamide (PAM) is a water-soluble polymer, which is insoluble in most organic solvents and has good flocculation property, which can reduce the friction resistance between liquids. According to ionic characteristics, PAM can be divided into four types: nonionic, anionic, cationic and amphoteric. (Note: Polyacrylamide is different from acrylamide)
Question 2: What kind of bait is this? In 2008, a mysterious bait-"jelly bait" quietly became popular. This bait is composed of a colloidal swelling powder as the main raw material and some auxiliary materials. This kind of colloidal swelling powder has strong water absorption. After blending, a small amount of it is atomized and dispersed after entering water, and then a transparent and shiny micelle is formed on the hook to wrap the hook tip. Because the bait looks like jelly when it comes out, it is called jelly bait.
The colloidal swelling powder I saw first appeared in Lily's Carassius auratus, but I also heard that it was the secret weapon for fishing Wang Hua in the field for many years, so it was impossible to verify who was the first to use it in the bait. Whoever it is is an admirable genius. In 2008, Tianyuan Zhougang Fishing Gear Co., Ltd. introduced a kind of "Goukou Crucian Carp", whose main component is colloidal swelling powder. In June, 2008, Longwanghen Fishing Gear Group launched "Goukou Crucian Carp" and "Jellyfish", which were the top jellyfish bait I saw at the 2009 Bihai (Langfang) Spring Fair. There are also Hong Kong Wuji, Nanbei, Zhongsheng and other companies that have similar jelly bait.
The reason why jelly bait made of colloidal swelling powder can make fishermen love it is to solve or partially solve the problem of repeated swallowing (commonly known as gargling) when eating. Most of the ingredients in the bait made by traditional grains or aquatic products are not absorbent, and it is difficult to find a delicate bait except snow pollen or other high-puffed things similar to snow pollen. The appearance of colloidal swelling powder can replace snow pollen well and play a better role. Colloidal swelling powder has great water absorption, and the ratio of bait to water is about 1: 4. Colloidal swelling powder used to be the size of salt particles, which swells rapidly when it meets water. After absorbing enough water, it can swell to 3 mm square, just like a neat colorless block cut from jelly.
Colloidal swelling powder itself has little viscosity, but it is not sticky when it meets water. In order to hook it, other adhesives need to be added, and after this adhesive is pecked by fish, the colloidal swelling powder can be dispersed. The jelly bait produced by different manufacturers has different effects because of the different adhesives used. Some manufacturers' jelly bait works well, but it is slightly sticky; Some manufacturers' products are not effective, but they solve the problem of sticking hands. At present, the author has not found a product that can perfectly combine the two, which is also the new expectation of the majority of fishermen!
The reason why jelly bait can deal with slippery fish is that after this bait enters the water, the colloidal swelling powder falls off when it meets water, and the glitter in the water can confuse the fish's eyes and attract their attention. Then there is a shiny residue on the hook, which just covers the hook tip. When a fish eats bait, the residual components covering the tip of the hook explode rapidly, and the remaining naked hook can be hooked as long as it touches the fish's mouth. The fish smacked its lips quickly. When it wants to vomit, there is no residue on the hook and it is easy to be hooked. On the contrary, its spit is one of the reasons for being hooked. This is different from the traditional bait, because it is sticky or wire drawing powder effect. When a cunning fish sucks the hook bait, the bait often winds around the hook and spits it out together. This is also the main reason why jelly bait was quietly popular in the arena in 2008. Its direct function is to improve the performance of fishermen and make them happy.
Colloidal swelling powder itself is tasteless, but the taste that fish like in the arena is unknown, so some jelly baits are tasteless after being made. Fishermen need to add flavors according to the situation of fish, such as Liuhe fragrance, Luke fragrance, strawberry fragrance, egg milk fragrance, pig breast milk fragrance, etc ... Some manufacturers have added broad-spectrum flavors, which can be adjusted by adding other flavors appropriately, but the dosage is difficult to grasp, and the effect is sometimes ideal and sometimes unsatisfactory.
Colloidal swelling powder is colorless after entering water, and some manufacturers will add some colors according to the preference of fish, such as yellow and red. However, after experiments, the author thinks that color and colorless have little effect on fish's feeding, mainly because taste plays a decisive role.
When jelly bait first appeared, it could only be wiped but not pulled, but in 2009, new products appeared to pull bait. This jelly bait is not wire drawing powder at work, but a mysterious substance. The appearance of jelly bait has changed the situation that jelly bait is only suitable for fishing slow-slippery fish, and it can also show its talents when fishing fast-slippery fish.
The author used many kinds of jelly bait. After the unused bait is thrown into the water, it can float on the water and get two inspirations. On the one hand, can you catch silver carp and bighead carp? On the other hand, the specific gravity of bait ball is light, so it must be different when setting fishing eyes, and it will be different when looking at the standard phase, which needs to be confirmed and summarized.
Many people who come into contact with jelly bait for the first time suffer from it >>
Question 3: What is the swelling powder for making steamed buns? Expansive powder is a kind of gel, which is a polymer of three materials: super absorbent resin (SAP), polyacrylate (potassium salt or sodium salt) and polyacrylamide. It is a white powdery crystal in natural state and expands several times when it meets water. Introduction of the above three materials: (1) Super absorbent polymer (SAP) is a new high functional fraction. ...
Question 4: What is swelling powder? The swelling powder is a kind of gel (super absorbent resin (SAP), polyacrylate (potassium salt or sodium salt) and polyacrylamide polymer). It is a kind of white powder crystal in nature, which expands several times when it meets water, making the bait loose and increasing the dissolution effect. It is a widely sold agricultural water-retaining agent. The crystal of food-grade pure high-efficiency puffed raw materials is square after absorbing water, and a small amount of puffed powder is added.
Question 5: What is the mysterious white powder added in fishing? Many things are the white powder you mentioned: wire drawing powder, brown powder, swollen powder, sticky powder, cold plum powder, protein sugar, bran,
Question 6: What was put in the bread and why did it swell so much? Bread yeast
In the 10 century BC, the Egyptians mastered the method of making this fermented bread, which was then called sour bread.
Egyptians are tight-lipped about the baking method of fermented bread. They wanted to keep this "patent" secret strictly, but the secret was known by the Romans and Greeks. European countries will bake fermented bread one after another, but no one understands why sour bread is soft.
1680, Levin Hooke observed yeast with a microscope and found that bread fermentation was the result of yeast action. 1870, Dutch Hansen invented the method of making artificial yeast for bread and beer.
People in China make bread very late, but steamed bread is white and mysterious. Steamed steamed bread is also inseparable from yeast. What exactly is yeast?
Yeast is a member of the microbial kingdom. Some of them are spherical and oval, others look like sausages, and most of them reproduce asexually by budding.
Yeast can decompose sugar (glucose) in fruit juice or wort into alcohol and carbon dioxide without oxygen, and turn sugar into wine. It can ferment free sugar in flour and produce carbon dioxide gas. During cooking, carbon dioxide expands when heated, so steamed bread becomes very soft.
Yeast cells contain a variety of vitamins, minerals and nucleic acids. The content of protein is the highest. It has been proved that every 100 kg of dry yeast contains protein, which is equivalent to 500 kg of rice and 2 17 kg of soybean or edible yeast developed by scientists. It looks like pork and beef, and people call it "artificial meat". During the Second World War, Germany produced edible yeast again, and then Britain and other countries rushed to study and produce this kind of "artificial meat". The development and utilization of edible yeast is considered to be the third great achievement after the invention of atomic energy and penicillin in World War II.
Yeast also helps to destroy people. If you have indigestion and loss of appetite, the doctor will prescribe some yeast tablets for you. After eating yeast tablets, your stomach will turn upside down, and those indigestible things in your stomach will be removed.
Yeast is widely distributed in nature, almost everywhere. When we mix dough, yeast comes uninvited and is called the mother of fermentation.
Question 7: The harm of expanded perlite to human body hurts the skin and causes dermatosis ~ ~ ~
Question 8: What is the structure of dense surface and porous inside?
Perlite is a kind of expanded perlite, Xinyang is called expanded powder. Mainly used as a thermal insulation filler for industrial thermal insulation. But in recent ten years, with the improvement of scientific research level of perlite, the application of perlite products has exceeded people's initial expectations, and the series of perlite products has been enriched. Especially in recent years, when perlite is widely used in civil buildings, it is more like a runaway wild horse, running fast in the contemporary society with the theme of energy saving and environmental protection. However, the names of perlite in the market are varied, which confuses perlite beginners. In order to explain the difference of different names, such as: perlite, perlite ore, perlite raw ore, perlite filter aid, floating beads, gardening perlite, perlite insulation board, etc. , you can refer to the "Standard Naming and Standardization Specification for Perlite Products" to understand the specific differences and standardized names.
The similarities and differences between "expanded perlite" and "vitrified beads" are discussed.
Similarities:
1. First of all, both of them are white granular materials made of perlite ore after preheating and instant high-temperature roasting and expansion, that is, the raw materials produced by both of them are the same, both of which are perlite ore.
2. Secondly, both of them are products with high temperature expansion, so they have the same chemical composition, are acid and alkali resistant, colorless, odorless and nontoxic, and belong to Class A refractories promoted by the Ministry of Construction.
3. Finally, both of them have certain micropores in their structures, so they have the characteristics of thermal insulation and sound absorption, and are widely used in building thermal insulation systems.
Difference:
1, structural difference: expanded perlite is open, and vitrified microbeads are closed, so vitrified microbeads are also called closed-cell perlite.
2. The processing equipment is different: the expanded perlite is heated and expanded by a gas producer, and the vitrified beads are expanded by an electric furnace.
3. Different water absorption rates: vitrified beads are not easy to absorb water, while expanded perlite has a large water absorption rate. Once absorbed, the thermal insulation effect of expanded perlite will be greatly reduced.
4. Different bulk densities: generally, expanded perlite is 70- 100kg/ m3, and vitrified beads are110-130kg/m3.
5. Different application ranges: vitrified beads are mainly used for external wall insulation, and expanded perlite is mainly used for roof and floor insulation.
Question 9: Is perlite powder puffed? Expanded perlite micropowder is called expanded perlite micropowder for short. This product is ultra-fine white powder perlite separated from the expanded perlite above the silo during expansion. This product is non-toxic, odorless, nonflammable and acid and alkali resistant, and is widely used for density adjustment of fireworks, fireworks chemicals, pesticides and daily chemicals. Therefore, perlite powder is a nonmetallic mineral product that expands at high temperature (about 1400 degrees Celsius), not expansion, but expansion and expansion are two concepts.
Question 10: Will ordinary silicate dust explode? Ordinary silicate, expanded perlite and leech ordinary silicate dust will not explode because it is not flammable. Explosive dust mainly refers to organic dust (wood dust, sugar dust, cotton dust, flour), coal dust and some metal dust (aluminum dust).
