Yuqori samarali Bundan tashqari, Kompyuter materiali yuqori harorat sharoitida ham yaxshi mexanik xususiyatlarga, barqaror o'lchamlarga va kichik o'tishga ega. Kengaytirilgan UL harorat indeksi 120 ~ 140 ℃ ga etadi (uzoq muddatli tashqi qarish ham juda yaxshi), dielektrik koeffitsienti 3,0-3,2 va yoy qarshiligi 120s. Bu elektron va elektr qismlarini ishlab chiqarish uchun ideal materialdir. Biroq, bu material yuqori haroratda suv ta'sirida parchalanishi oson, shuning uchun u yuqori harorat va yuqori namlik muhitida ishlatilsa, ehtiyot bo'lish kerak. Kompyuter materiali ham yaxshi ishlov berish xususiyatlariga ega va oddiy asbob-uskunalar yordamida inyeksion kalıplama yoki ekstrusion kalıplama yo'li bilan hosil bo'lishi mumkin. maxsus shakldagi hujayra madaniyati kolbasi bo'lib, sutemizuvchilar hujayralari va hasharotlar hujayralarining suspenziya madaniyatida muhim rol o'ynaydi. Materialni tanlash nuqtai nazaridan, ushbu sarf materiali yuqori shaffoflik, kuchli zarba qarshiligi va yuqori haroratga chidamliligi 121 ° C bo'lgan polikarbonatdan (PC) ishlab chiqariladi. molekulyar zanjirdagi guruhlar. Rangsiz va shaffof. Strukturaviy o'ziga xosligi tufayli u beshta asosiy muhandislik plastmassalari orasida tezroq o'sish sur'ati bilan umumiy muhandislik plastmassasiga aylandi. Kompyuter materiali sintez qilinganda, BPA qo'shiladi, lekin BPA hujayra o'sishiga ta'sir qilishining oldini olish uchun yuqori samarali erlenmeyer chayqaladigan shisha hujayralar uchun yaxshi o'sish muhitini ta'minlash uchun BPAsiz kompyuterdan foydalanadi.
PC materiali yuqori samaradorlik
uchun tez-tez ishlatiladigan ishlov berish materialidir. Bundan tashqari, PETG materiali yuqori samarali silkituvchi flakonlar uchun ishlov berish xom ashyosi sifatida ham ishlatilishi mumkin. Mijozlar turli ehtiyojlarga ko'ra tanlashlari mumkin.
erlenmeyer shishalarni silkitadierlenmeyer shake flasks. In addition, PETG material can also be used as a processing raw material for high-efficiency shake flasks. Customers can choose according to different needs.
The FAI climbed 5.9 percent year-on-year in the first 11 months of 2018, quickening from the 5.7-percent growth in Jan-Oct, the National Bureau of Statistics (NBS) said Friday in an online statement.
The key indicator of investment, dubbed a major growth driver, hit the bottom in August and has since started to rebound steadily.
In the face of emerging economic challenges home and abroad, China has stepped up efforts to stabilize investment, in particular rolling out measures to motivate private investors and channel funds into infrastructure.
Friday's data showed private investment, accounting for more than 60 percent of the total FAI, expanded by a brisk 8.7 percent.
NBS spokesperson Mao Shengyong said funds into weak economic links registered rapid increases as investment in environmental protection and agriculture jumped 42 percent and 12.5 percent respectively, much faster than the average.
In breakdown, investment in high-tech and equipment manufacturing remained vigorous with 16.1-percent and 11.6-percent increases respectively in the first 11 months. Infrastructure investment gained 3.7 percent, staying flat. Investment in property development rose 9.7 percent, also unchanged.
