First, the effect of moisture on plastic

Moisture content influences such as polyamide (PA) and polycarbonate (PC) resin such as pro

cessing technology, an important factor in the appearance and characteristics of the product. In

 the injection molding process, if the moisture content is too high for the production of plastic pa

rticles, it will produce some processing problems, and ultimately affect the quality of finished pr

oducts, such as: surface cracking, reflective, as well as impact resistance and tensile strength a

nd other mechanical properties and decreased . Therefore, the control of moisture content for p

roducing high quality plastic products is crucial. Detecting the moisture content of the plastic pr

oduction process is a necessary step. Currently detect moisture analyzer includes an infrared r

apid moisture meter and halogen Moisture Analyzer. Halogen Moisture Analyzer for its heat sou

rce is circular, plastic during the test, the heat more evenly and will not appear scorched plastic 

phenomenon, it is more appropriate plastic water testing.

Second, the principle:

Halogen Moisture Analyzer is heating new rapid water testing equipment. Ring halogen ensure

 uniformly heated, easy to operate, accurate measurement. Moisture in measuring sample at th

e same time, the instrument using ring halogen heating tube form, fast drying sample during the

 drying process, the moisture meter measured continuously and instantly displays the sample lo

st water weight%, after the drying process is complete, the final determination of moisture cont

ent lock the display in the value. Compared with international oven heating, halogen heating at h

igh temperature rapid drying evenly sample, the sample should not damage the surface, its test

 results with the national standard oven method has good agreement with the irreplaceable, an

d the detection rate is much higher in oven method. General sample just a few minutes to compl

ete. The instrument operation simple, the test is accurate, some with LCD display - the screen i

s more clear and bright, clearly visible indication, respectively, to display the value of water, the 

sample initial, final value, measured time, temperature, initial, final value and other data, and ha

ve the computer, printer connectivity.

Our test machine market processes tend Analysis

Our test machine market processes tend Analysis

With the growing demand of the international market, with people's lives, the testing machine industry has been rapid development, but due to technical and other aspects of innovation, there is still a huge gap between domestic and foreign testing machine industry, the lack of core technologies,low-level redundant, product stability and reliability can not be fundamentally resolved, in the high-end precision instruments still heavily dependent on imports, large imports adversely affect the industry.

Metals, non-metallic, high-temperature alloys, high-molecular compound and other materials to achieve the best use of the important factors, in addition to the factors structural design, processing techniques, and its physical properties is an indispensable , testing machine is used for measure the physical properties of the material of choice for equipment and essential tools. With the development and improvement of industrial production requirements of global science and technology, once rare test machine industry is now out of purdah, it said to the people growing market potential and strong momentum of development of this industry, the data show that China's test machine market Total sales of up to 4 billion yuan annually.

Testing Machine market prospects are so good, but lack of universal testing machine manufacturing technology research and development, product updates slow, and the domestic high-end market testing machine has been monopolized by foreign manufacturers. How our test machine how companies break through the bottleneck and create localization testing machine brand, then gradually enter the high-end market, and ultimately achieve sound development of the testing machine industry? I believe many domestic testing machine experts, users and manufacturers are struggling to find the breakthrough!

  

Currently, the test machine mainly for testing and analysis of mechanical properties for strength, stiffness, hardness, elasticity, ductility, toughness, ductility, surface and internal defects and other parameters of the material can be widely correspond to the mining companies, metrology departments, research centers on-site laboratory, and the specific areas related to aerospace, machinery manufacturing, petrochemical, food, pharmaceutical packaging, vehicle manufacturing, wire and cable, textile fibers, plastics, rubber, building materials and other industries.

Moreover, with the extensive application of the testing machine, testing of material properties in the workforce has become quite large. Alone in terms of professional meetings at home and abroad will be held every year very large variety of mechanical conferences such as the International Conference on fracture mechanics, fatigue fracture meetings, conferences and other conventional mechanics.

Tester has been European countries limit the export of cutting-edge scientific research products, therefore, our test machine to create a national brand, and enhance market competitiveness of domestic testing machine is very important. The current face of competition of imported products, we expect domestic tester companies go its own way, make our own machine to test.On how to break the bottleneck in the development of our test machine industry asked Professor Wang Chunsheng case to answer, at present, the development of our country should focus on the test machine industry from the following aspects:

(1) The Government should increase support

Tester is a microcosm of the country's overall level of manufacturing, the government should give enough attention to the testing machine industry and support appropriate to increase R & D investment projects testing machine related topics, concerns and support the development potential of the domestic testing machine manufacturers, guidance and Regular and orderly development of the testing machine industry.

(2) speed up the training of comprehensive talent

Test machine is a mechanical, electrical, mechanics of materials, laboratory standards and computer technology-intensive high-tech products, involving a very wide range of subjects. But now, our country has no such professional counterparts, domestic staff in mechanics from almost all transfer materials, mechanical design, physics and other related professional over, therefore, the government, society, schools multiparty cooperation, speed up the training of specialized integrated talent.

 

(3) improve business ideas, increase R & D investment

Today in the market, business R & D investment is not so much the problem of inadequate, as it is the enterprise management philosophy is more appropriate. Manufacturers to sell goods to make a profit, you can not say no, but not at the price war as the premise, the key is to consider how to improve product quality, performance and price, followed by another increase in R & D investment. Thus forming a virtuous circle, eliminate backward enterprises, the formation of several highly competitive domestic testing machine manufacturing enterprises, and ultimately promote the healthy development of the industry.

Overall, our test machine industry is still promising. Domestic enterprises look to put the long-term, based on the gap between domestic and foreign products, while ensuring the economic benefits, strong R & D of new technology, improve product performance, in order to expand the market. We only have to create a brand belonging to China's test machine, in order to gradually increase domestic tester position in China, and the global market.
