The chemical reaction time of the tendon planting glue
The chemical reaction time of the glue was affected by the temperature of the base material: - When the base material temperature was-5 ° C to 0 ° C, the initial setting time was 20 minutes, the installation time was 30 minutes, and the curing time was 5 hours. - When the temperature of the base material was 0 - 10 ° C, the initial setting time was 15 minutes, the installation time was 20 minutes, and the curing time was 3 hours. - When the base material temperature was 10 - 20 ° C, the initial setting time was 10 minutes, the installation time was 16 minutes, and the curing time was 2 hours. - When the base material temperature was above 20 ° C, the initial setting time was 5 minutes, the installation time was 12 minutes, and the curing time was 1 hour. In addition, it was also mentioned in other materials that when the base material temperature was 5 ° C, the installation time was not less than 60 minutes and the curing time was 90 hours; when the base material temperature was 15 ° C, the installation time was not less than 45 minutes and the curing time was 72 hours; when the base material temperature was 25 ° C, the installation time was not less than 30 minutes and the curing time was 48 hours; when the base material temperature was 35 ° C, the installation time was not less than 20 minutes and the curing time was 24 hours.

The chemical reaction of feelings
The chemical reactions in relationships involved biological processes. The brain releases chemicals such as Dopamine, Pitocin, and Serotonin that make people feel pleasure, attachment, and love. This effect is similar to the addiction caused by drugs. From the perspective of brain science and psychology research, romantic love was a biological program. Caring behavior stemmed from a variety of attractive forces. From a biological point of view, love was dominated by evolutionary forces and acted through hormones, of which Dopamine played a leading role. For example, among couples who have been in a relationship for 20 years, about one-tenth of them will quickly secrete a large amount of adrenaline in their brains after seeing a photo of their lover, which may cause love to fade or break up. The longest shelf life during a relationship could be four years, but many people chose to stick to their love because of responsibilities, children, parents, and other factors. Some people continued to inject new energy into their love to extend the duration of their love. In addition, people with different personalities would have different " chemical reactions " when they were together. For example, fawning personalities and highly sensitive personalities were more sensitive and delicate, and they would attract each other. However, due to different core needs, fawning personalities often suffered when they got along. Moreover, there was the Romeo and Juliet effect. When there were external forces that interfered with the relationship between the two parties, the relationship between the two parties might be stronger.
The chemical reaction of love
Brain science and psychological research showed that love was a biological program. From a biological point of view, love was dominated by the power of evolution, and it was affected by hormones. All caring behaviors stemmed from multiple attractions, and crazy behaviors were to pass on genes to future generations. Dopamine played a leading role. About one-tenth of partners who had been together for 20 years would quickly secrete a large amount of Dopamine in their brains after seeing a photo of their lover. In addition, the feeling of obsession was a hormone that secreted phelethylamin (PPA), which was similar to dopamine-induced intoxication. It was only effective for 18 to 36 months for the same stimulant.

The chemical reaction of love
Here are some statements about the chemistry of love: - " Your magnesite stole my zincate." According to the chemical equation," MG + ZnSO"==" MGSO"+ Zn ", this was a creative statement that expressed love in the homonym of chemical elements. - " Entropy becomes negative, and quotient becomes positive. Even if the world is at absolute zero, I will still love you spontaneously." This was using the concepts of the change of the chemical temperature and the change of the chemical temperature to express the firmness of love. - " Falling in love with you is like the Le Chatelier principle: even if the result is the same, I have also gone against the current." Using the principles of chemistry to describe the attitude in love. - " I'm like the Manganese Dioxygen in the hydrogen peroxide-reaction. Even if the world is broken, my persistence for you will never decrease." Through the reaction of hydrogen Peroxide-Manganese Dioxide-Catabolized Reaction, it expressed the persistence of love. - "I'm willing to be your reducing agent. It doesn't matter how many electrons I give you. I just want to be with you steadily." The chemical concept of reducing agents losing electrons was used to express the expectation of stable love. - " If life is a chemical balance, your every word and action is moving my balance." He compared life to a chemical balance to reflect the other party's influence on his emotions and other aspects. - "The nitrogen dioxide says to the air: I blush at the sight of you. Ever since I fell in love with you, my PH has always been less than 7." Using the characteristics of chemicals and the concept of pH value to express the shyness and excitement in love.
How is the reaction mechanism of a chemical reaction obtained?
Reaction mechanism was used to describe all the basic reactions that a chemical change went through. Although the material transformation of the entire chemical change may be obvious, in order to explore the reaction mechanism of this process, experiments were often needed to verify it. The order of each step in the reaction mechanism was very important. It described the process of each step in detail, including the formation of transition states, the breaking and formation of bonds, and the relative speed of each step. A complete reaction mechanism needed to consider the reagents, catalyst, reaction's chemistry, products, and the amount of each substance. The net reaction obtained by adding all the elementary reactions must be the same as the original reaction, and the rate equation of the total reaction is determined by the slowest step in the reaction mechanism (the rate-controlling step). For example, some chemical reactions looked like a one-step reaction, but in fact, they went through multiple steps. This required the rate equation to be measured through experiments to infer the possible reaction mechanism. In 1903, Arthur J. Lapworth proposed the first organic reaction mechanism by studying the condensation reaction. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Is water absorption a chemical reaction or a physical reaction
Water absorption was usually a physical property that was reflected in physical changes, but some also involved chemical changes. For example, the solid state of soda ash had a strong moisture absorption. It absorbed the surrounding water vapor and dissolved in the absorbed water, forming a concentrated solution of soda ash. This process was a physical change. The concentrated sulfuric acid could absorb the water vapor in the air around it to form a series of water compounds. On the other hand, the concentrated sulfuric acid dissolved in the absorbed water to make itself thinner, which also involved physical changes. However, the concentrated sulfuric acid absorbed the first water molecules in the copper sulfuric acid, which reflected the water absorption (physical property), and the removal of the remaining four water molecules reflected the dehydration (chemical property). The main component of the quicklime drying agent was lime, and its water absorption ability was achieved through a chemical reaction. This water absorption was irreversible. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Is love the result of a chemical reaction?
From the perspective of biology and brain science, love can be seen as the result of a chemical reaction. Research has found that love is a biological program that is produced by a variety of chemicals acting on the brain. When the brain releases chemicals such as Dopamine, Pitocin, and Serotonin, it causes feelings of pleasure, attachment, and love. Romance and passionate love were dominated by evolutionary forces and acted through hormones. The leading hormone was Dopamine, which would promote people to have some behaviors related to love. Its fundamental purpose was to pass on genes to future generations. However, love was not entirely determined by chemical reactions. Social, cultural, personal experiences and other factors would also affect love.

A beautiful sentence of chemical reaction
Here are some beautiful sentences about chemical reactions: 1. The nitrogen dioxide said to the air, I blush at the sight of you. 2. Particles have existed since the birth of the universe, and they created us. I often think that these atoms used fourteen billion years to travel through time and space to create us so that we could meet and complete each other. 3. Although iron is slowly oxided, it is still a chemical reaction. As long as you have this little bit of air around you, it will turn into iron dioxide sooner or later. 4. Although scholars used beautiful words to describe love, for scientists, long-term and loyal love was just a chemical reaction in the brain under the stimulation of various hormones.
