Experiment § Vacuumed Potting Polyurethane with High Hardness and High Toughness
FZ090 series is polyurethane molding potting resin which mixing ratio is 1:2. It exhibits low viscosity: Part A is <1000 cps, 25℃; Part B is <300 cps, 25℃ that is convenient for mixing and potting. When vacuumed, evenly mix Part A and Pat B, then potting into silica gel mold and demolding with heat-curing that can get polyurethane roll over molded product. To compare with steel, the cost of using silica gel mold is lower and can adjust the finished product, especially for initial development. FZ090 series take hardness and toughness into acount to avoid the problem of brittle crack. (Figure 1, 2) Cured product exhibits similarproperties with ABS. To maintain hardness and toughness roll over molded products, we choose high functional group and low equivalent resinto enhance crosslinking density to enhance Tg= 125℃ and Shore D= 80. It is important to choose the type of resin to maintain toughness with high hardness. To enhance the efficiency of rollover molding, this series offers faster reaction rate. It can fast demold without deforming within 25 minutes and its surface dry time is 5 minutes at 70℃. Although mixing under vacuumed environment with less CO2 when reacts with water vapor, but producing more bubbles. With excellent defoaming property of FZ090 series, it is beneficial to apply on vacuumed potting. (Figure 3) This series product can product different color and similar to colorless formula. We can also customized adjust. If you are interested in our products, welcome to contact us. Author: Ms. Ching-An, Lei
Activity § Recent Public Welfare
Everwide has donated money to support plantation plan for many years. We continue to participating to contribute our share for sustainable environment, also answers the call of ESG. (Figure 1, 2) Besides of the concern for environment protection, we deeply realize the importance fo cultural inheritance. To make the kids have more ways to understand Taiwan, we particularly donated money to invite “FORMOSA 3D” to performance tour at Yunlin County Shiliu Junior High School. The director spent 10 years to record ten endangered Taiwanese landscapes and 100 traditional artisans who may be forgotten to make everyone can remember Taiwanese history culture and natural resources. (Figure 3-5) We hope to take actual actions to deliver “Goods” to everywhere and to make this world a better place.
Knowledge § What is Reactive Type Inorganic Adhesive? (1)
Reactive type inorganic adhesive requires mixing curing agent to achieve the purpose of bonding. Curing temperature is about room temperature to 300 ℃. This kind of product will add framework materials, such as ceramics powder to enhance the mechanical property and heat resistance. The two typical types are “silicate” and “phosphate” which can resist over 1,000℃. Water will not “directly” react, but may “indirectly” react. Besides, this are examples that will not cure but cause other reactions. No matter what kind of circumstances. Water has a significant impact on the resin.
Living § A Big Crowd of People in Chiayi
For hot showing of movie “KANO”, tourism in Chiayi has become famous overnight. Even now, tourists come one after the other on consecutive holidays. Crowded Wenhua Road Night Market is the best example. (Figure 1) When it comes to delicacy in Chiayi, the most representative dish is turkey rice. There are many turkey rice restaurants that each one has its own loyal supporters. My favorite one is “A Hong Shi Turkey Rice.” Their turkey rice and pork knuckle rice are delicious since the meat is soft and tasty. When eating with specially made sauce, it makes people leave a rich aftertaste. (Figure 2) After dinner, you can take a walk in “Lan Pond Dam” where are graceful and romantic landscapes called “musical fountain” and “Moonlight Lake.” It is recommended to increase exposure value when picturing for better shooting effect. (Figure 3) Besides, deciduous cypress in reorganized “Minxiong Forest Park” deserves a look in Minxiong, Chiayi. (Figure 4) Last of all, I recommend my alma mater “National Chung Cheng University” with sunset in Tranquility Lake, rainbow in fountain, Golden bell tree, Madagascar Almond Avenue are voted as the most beautiful university. (Figure 5) There are a large number of landscapes and delicacy in Chiayi. There is no harm in planning to take a pleased trip in Chiayi and enjoy the delicacy, shopping, experiencing the charm of humanities and arts. Author: Dr. Zheng-Yang, Ye
