The fittest coupled turn number of the screw nut is designed to make sure the strength of coupled teeth and make every turn of the screw thread go on very well and also save material.
And the screw thread with more turns needs to add more material.
So the maximum axial pressure can be calculated according to material's yield strength.

Experiments Raw Materials and Pretreatments.
Three raw materials' main chemical compositions are listed in Table 1.
They can be used as adsorption material, Moreover they are endowed with higher compressive strength, thus can be used as building materials.

Introduction: Polymer Nanocomposites develop rapidly in recent years, nanomaterials add in nanocomposite materials will affect the crystallization behavior of materials, thus affecting the processing properties of the material.[1] At the same time the crystallization process is a key factor to decide the structure of crystalloid and the degree of crystallinity in the forming process, different polymer structure will affect crystallization ability and crystallization speed, while the structure of crystalloid and the degree of crystallinity decide the meterial’s physical, chemical and mechanical properties.
Fig 2.4 shows that the linear deviation grows rather bigger in the late stage of crystallization of nano composite materials with endothermic agent than the pure PET, and the starting time spot advances with the cooling rate increases.
