{{Flavour_quantum_numbers}}
 
In [[particle physics]], the '''baryon number''' is an [[conservation laws|approximate conserved]] [[quantum number]] of a system. It is defined as
::<math>B = \frac{1}{3}\left(n_\text{q} - n_\bar{\text{q}}\right), </math>
where ''n''<sub>q</sub> is the number of [[quark]]s, and ''n''<sub>{{overline|q}}</sub> is the number of [[antiquark]]s. [[Baryon]]s (three quarks) have a baryon number of +1, [[meson]]s (one quark, one antiquark) a baryon number of 0, and antibaryons (three antiquarks) have a baryon number of &minus;1. [[Exotic hadron]]s like [[pentaquark]]s (four quarks, one antiquark) and [[tetraquark]]s (two quarks, two antiquarks) are also classified as baryons and mesons depending on their baryon number.
 
==Baryon number vs. quark number ==
{{See also|Color charge}}
 
Quarks do not only carry [[electric charge]], but also additional [[charge (physics)|charges]] such as [[color charge]] and [[weak isospin]]. Because of a phenomenon known as ''[[color confinement]]'', a [[hadron]] cannot have a net [[color charge]]; that is, the total color charge of a particle has to be zero ("white"). A quark can have one of three "colors", dubbed "red", "green", and "blue".
 
For normal hadrons, a white color can thus be achieved in one of three ways:
*A quark of one color with an antiquark of the corresponding anticolor, giving a [[meson]] with baryon number 0,
*Three quarks of different colors, giving a [[baryon]] with baryon number +1,
*Three antiquarks into an antibaryon with baryon number &minus;1.
 
The baryon number was defined long before the [[quark model]] was established, so rather than changing the definitions, particle physicists simply gave quarks one third the baryon number. Nowadays it might be more accurate to speak of the conservation of '''quark number'''.
 
In theory, [[exotic hadron]]s can be formed by adding pairs of quark and antiquark, provided that each pair has a matching color/anticolor. For example, a pentaquark (four quarks, one antiquark) could have the individual quark colors: red, green, blue, blue, and antiblue.
 
==Particles not formed of quarks==
 
Particles without any quarks have a baryon number of zero. Such particles include [[lepton]]s ([[electron]], [[muon]], [[tau (particle)|tau]] and their [[neutrino]]s) and [[gauge bosons]] ([[photon]], [[W and Z bosons]] and [[gluons]]); or the hypothetical [[graviton]].
 
==Conservation==
{{See also|Conservation law}}
 
The baryon number is conserved in nearly all the [[fundamental force|interactions]] of the [[Standard Model]]. 'Conserved' means that the sum of the baryon number of all incoming particles is the same as the sum of the baryon numbers of all particles resulting from the reaction. An exception is the [[chiral anomaly]]. However, [[sphaleron]]s are not all that common. Electroweak sphalerons can only change the baryon number by 3.
 
The still hypothetical idea of a [[grand unified theory]] allows for the changing of a [[baryon]] into several [[lepton]]s (see [[B − L|''B'' − ''L'']]), thus violating the conservation of both baryon and [[lepton number]]s.<ref>{{cite book |last=Griffiths |first=David |authorlink=David Griffiths (physicist) |title=Introduction to Elementary Particles |edition=2nd |year=2008 |publisher=John Wiley & Sons |location=New York |isbn=9783527618477 |url=http://books.google.com/books?id=Wb9DYrjcoKAC&lpg=PA77&dq=%22In%20the%20grand%20unified%20theories%20new%20interactions%20are%20contemplated%2C%20permitting%20decays%20such%20as%22%20%22in%20which%20baryon%20number%20and%20lepton%20number%20change.%22&pg=PA77#v=onepage&q=%22In%20the%20grand%20unified%20theories%20new%20interactions%20are%20contemplated,%20permitting%20decays%20such%20as%22%20%22in%20which%20baryon%20number%20and%20lepton%20number%20change.%22&f=false |page=77 |quote=In the grand unified theories new interactions are contemplated, permitting decays such as {{SubatomicParticle|link=yes|Proton+}} → {{SubatomicParticle|link=yes|Positron}} +  {{SubatomicParticle|link=yes|Pion0}} or {{SubatomicParticle|link=yes|Proton+}} → {{SubatomicParticle|link=yes|muon antineutrino}} +  {{SubatomicParticle|link=yes|Pion+}} in which baryon number and lepton number change.}}</ref> [[Proton decay]] would be an example of such a process taking place, but has never been observed.

There are a number of chemical procedures that require catalysts for the reactions to be completed. These are responsible for the proper functioning of the chemical reactions, so that the desired results can be achieved.

If you have any type of concerns pertaining to where and exactly how to make use of resina epoxi, you could call us at the web page. Reactive thinners are one of these catalysts which are widely used in different ways and forms to get the most useful results with the help of the same. The use of epoxy resin in different forms can be done only with the help of adding the right amount of diluent in it.

They are used to form adhesive bonds that are strong and even unbreakable at times. It's essential you understand the specific characteristics of diluents so that you know mixing them in what proportion is going to get you what sort of results.

You need to properly understand about the characteristics of these diluents so that you can use them according to your needs and requirements to get the desired reactions in the end.

The first and most visible quality of a diluent is the fact that it increases the solubility of the agent you mix it with. This means that when you mix the reactive, it shall reduce the viscosity or the thickness of the material.

This is what makes it really important when you need to use a thinner form of a particular chemical. It basically helps in reducing the molecular weight of the epoxy resins. They tend to make diluted counterparts of the pure form of the chemical which can be used for various applications.

The next advantage of it is that the vapor they produce resultantly has a low content of pressure. Another great feature of these reactive diluents is that they tend to reduce the substance and the wetting capability of the fillers that are made for using these adhesive joints.

It helps the agent become water and chemical resistant as well and they cannot tend to have harmful effects on it through their set of reactions.

Listed below are a few typical uses of these diluents with epoxy:

Flooring-While creating seamless floors for homes, this strong form of adhesive is used because it one of the most strong and long-staying adhesive that can be counted upon to stay put for a long time.

Another form of application epoxies with diluents is in the leather industry. Each product is careful coated with an efficient layer of epoxy because it helps to render properties such as water resistance, shine, and a finished and smooth look.
