Yuqori samarali erlenmeyer silkituvchi kolbalarhujayra madaniyatida keng tarqalgan sarf materiallari hisoblanadi. Ular asosan sutemizuvchilar hujayralari, hasharotlar hujayralari, xamirturush hujayralari, qo'ziqorin hujayralari va boshqa suspenziya hujayralarini etishtirish uchun ishlatiladi. Polikarbonat (PC) qayta ishlash uchun keng qo'llaniladigan xom ashyo hisoblanadi.
Yuqori samarali erlenmeyer silkituvchi kolbalar hujayralarni etishtirishda real vaqtda hujayralarning o'sish holatini kuzatishi kerak, shuning uchun shaffoflik Kompyuter materiali nisbatan yuqori. Bundan tashqari, ushbu material quyidagi xususiyatlarga ega:
1. Mexanik xususiyatlar: yuqori quvvat, charchoqqa chidamlilik, o'lchov barqarorligi va kichik o'tish (yuqori harorat sharoitida juda kam o'zgarish);
2. Issiqlik qarish qarshiligi: yaxshilangan UL harorat indeksi 120 ~ 140 ℃ ga etadi (uzoq muddatli tashqi qarish qarshiligi ham juda yaxshi);
3. Erituvchiga chidamlilik: stress yorilishi yo'q;
4. Suvga barqarorlik: yuqori haroratda suvda parchalanishi oson (yuqori harorat va yuqori namlik muhitida ehtiyot bo'ling);
5. Izolyatsiya ko'rsatkichlari: a'lo (namlik va yuqori haroratda ham barqaror elektr ish faoliyatini saqlab turishi mumkin, bu elektron va elektr qismlarini ishlab chiqarish uchun ideal materialdir);
6. Dielektrik koeffitsienti: 3,0-3,2;
7. Ark qarshiligi: 120s;
8. Kalıplamaning qayta ishlanishi: oddiy uskunani quyish yoki ekstrusion kalıplama.
Yuqoridagilar hyuqori samaradorlik erlenmeyer kolbalarni chayqatish ning moddiy xususiyatlari. Ushbu material uchun ishlatilishi mumkin bo'lgan ishlov berish texnologiyasi inyeksion kalıplama, ekstruziya, qoliplash, puflash va hokazolarni o'z ichiga oladi. Qoliplashdan oldin uni oldindan quritilishi kerak, namlik miqdori 0,02% dan kam bo'lishi kerak va iz namlik yuqori darajada qayta ishlanadi. harorat. Bu mahsulotda oq loyqa rang, kumush sim va pufakchalar paydo bo'lishiga olib keladi. Kompyuter xona haroratida sezilarli darajada majburiy yuqori elastik deformatsiya qobiliyatiga ega.
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.
