From the molecular structure point of view, the reason why the compound has the ability to resist the destruction of external forces mainly depends on the chemical bonding force in the molecule and the van der Waals force and hydrogen bond that the molecule smells(black silicon carbide). It is meaningful to calculate the theoretical strength of the encapsulated compound from a microscopic perspective, it is found that there is a huge gap between the theoretical strength and the actual strength(220 grit aluminum oxide).

They are generally referred to as "cold control", on the other hand, the two stretching processes are different(white aluminium oxide). The potential to increase the actual strength of the polymer is great. There are many factors that affect the actual strength of the dish. When the molecular weight is low, the tensile strength and impact strength are both low(garnet abrasive). There are also some differences in the effect of molecular weight on controlled tensile strength and impact strength.


Because comparing the theoretical calculation results with the actual polymer strength(brown fused alumina), we can understand the gap between them, this gap will guide and promote people to improve the actual strength of polymer research and exploration. For example, aromatic nylon has higher strength and modulus than ordinary nylon, polystyrene is more resistant to aliphatic polyacrylic acid(black aluminum oxide), and double-banded A home carbonate is higher than aliphatic polybasic acid.


If the arrangement direction of the molecular chain is parallel to the force direction, then the chemical bond may be broken or the molecule will slip off when it is broken(pink aluminum oxide); if the arrangement direction of the polymer chain is perpendicular to the force direction, it may be van der Waals For the destruction of force or hydrogen bond, by comparing the values of the theoretical controlled tensile strength (or breaking strength) and the actual strength of the three cases(garnet suppliers).


In general, they can be divided into two categories(brown aluminum oxide): one is related to the material itself, including the chemical structure of the polymer, molecular weight and its distribution, branching and cross-linking, and product Orientation, plasticizers, blends, fillers, stress concentrators, etc(silicon carbide abrasive). The other category is related to external conditions, including temperature and humidity, light, oxidative aging, speed of force, etc., which are separately discussed below.


For example, the controlled tensile strength of low-pressure polyethylene is only 15 to 16 MPa(green silicon carbide), polyoxyethylene marriage has polar groups, tensile strength is 50 MPa, nylon 610 has hydrogen bonding, tensile strength is 60 MPa, polar groups or oxygen bonding The greater the density, the higher the strength, so the tensile strength of nylon 66 is greater than nylon 610, up to 80MPa(glass bead blasting media suppliers). As the molecular weight increases, the tensile strength and impact strength will increase.


If the polar group is too dense or the substitution group is too large, it hinders the movement of the segment and can not achieve forced elastic deformation, which is shown as brittle fracture(brown aluminium oxide). Therefore, although the tensile strength is large, the material becomes brittle(steel grid). The polymer with aromatic heterocycle in the main chain has higher strength and modulus than the aliphatic main chain, so most of the new engineering plastics contain aromatic heterocycle in the main chain.
