Waterproof coating fabric after sewing, the durability and water proofing property is affected for the seam.
Under the premise of the fabric can play a role in waterproof, permeability is a key factor affecting the wearing comfort of human body.
There are many factors that Waterproof and breathable performance will be affected for the waterproof and breathable coating fabric.
The role of surface coating processing is to give good mechanical strength, wear-resisting property, scrub resistance and other apparent performance.

For example, water affects the structural use of wood by changing the mechanical properties (stiffness, strength, creep) and dimensions of the material [3, 4, 5].
The intensity of wood impregnation is influenced by several factors related to the capillary structure of the material.
When interacting, the properties of both components change.

The sulfate content of the corrosive solution and the limestone content in cement are the factors mostly intensifying the attack caused by MgSO4 and Na2SO4/K2SO4 solutions, respectively.
At later stages, formation of silica gel and M─S─H (with no binding properties) is expected [9].
This salt was found to affect the integrity of the material at higher depth, compared to Na2SO4, K2SO4 and MgSO4, while led to faster degradation of mechanical properties and expansion [13].
Time and space factors were not considered for the calculations.
The damage pattern of C─S─H is not affected by the sulfate content of this solution.

Fly ash content, especially CaO and MgO, are the key factors affecting the cracks tendency on the surface of cement paste, due to expansion.

Static analysis and dynamic analysis of CNC machine center based on ANSYS Xiaochen Pang1, a Hong Guo1, b 1Department of Mechanical＆Electronic Engineering, Jiangyin Polytechnic College, Jiangyin Jiangsu,China axcpang@163.com bguohong_72@163.com Key words: CNC machine center; FEA; modal analysis; structure design Abstract: The static characteristic and dynamic characteristic of machine tool is one of the most important factors that affect the performance of machine tool, and it will affect the manufacturing final performance of the machine tool, and it is also an important index to evaluate the machine tool of high performances.
The influencing factors to working accuracy were pointed out and a way was proposed to improve the structure of the machine center.
It is hard to fully disclose the whole property of machine tool by only analyzing individual part.
Especially, dynamic and static stiffness affecting working accuracy and accuracy stability of CNC directly, so it is very important to study the dynamic and static characteristics of complete machine.
Dynamic characteristics analysis The dynamic characteristics of machine tool are the key factors that affect machine performance, and directly affect the final processability of machine tool and are important indicators to evaluate machine performance.

In this analysis, the effect of the interfacial properties between the piezoelectric patches and the host structure on the EMI signatures is considered and thus a coupled structural system consisting of PZT patches, bonding layer and host structure is then investigated.
The effects of various parameters including the material properties of the adhesive, the crack depth and the crack position etc. on the EMI signatures are highlighted.
On the other hand, due to high frequency excitation used in EMI method, minor defects between the PZT patches and the host structure may influence the output EMI signatures significantly [3] and thus the interfacial properties should be considered carefully.
The material properties [6] of PZT wafer and the host structure as well as the adhesive are listed in Table 1 and 2, respectively.
The further parametric study indicates that some parameters such as the crack depth and position affect remarkably EMI signatures.

Major factors affecting the desulfurization such as weight ratio of CaO to total, types of modifiers, desulfurizer particle size, bed temperature were investigated.
In this study, a kind of new desulfurizer, made of ATP and CaO, was prepared, and its properties were studied.

The mechanical properties, such as elastic modules and fracture toughness, of the resulting coating are determined using the indentation tests.
Qiao et al. [6] indicated that worn out of the WC grains and the lifting of entire splats was affecting the sliding wear.
In addition, the effect of carbide size and cobalt content on the microstructure and mechanical properties of HVOF WC-Co coating were examined by Chivavibul et al. [7].
They analyzed the microstructures of the resulting coatings and they showed that the binder phase was a key factor affecting the microstructure of the coating.

After the welding operation, the quality of the welding seam is evaluated by means of its mechanical properties and tightness.
In general these sheets are contaminated with lubricants and the omission of the cleaning process shows up in an observable degradation of seam quality, e.g. mechanical properties and surface discontinuity [2, 3].
Thereby different influencing factors are varied and the results are considered.
The design of the process factors was a quadratic, d-optimal design (22 design runs and 2 replicates) and the model was created with the RSM target (Response Surface Modelling).
These two factors are helpful to evaluate the correlation between the experiment results and the created model.
