Cell fabrikalarikeng miqyosli hujayra madaniyatida ishlatiladigan sarf materiallari. Hujayralar o'sish muhitiga yuqori talablarga ega va o'ziga xos harorat, osmotik bosim, gaz fazasi va pH qiymatini talab qiladi. Shuning uchun hujayra zavodi hujayra o'sishi tashuvchisi sifatida hujayra o'sishi uchun shartlarga javob berishi kerak. , odatda toza ustaxonaning C-sinf standarti ostida ishlab chiqariladi.
Toza ustaxona toza xona yoki toza xona deb ham ataladi, bu esa zarrachalar, zararli havo, bakteriyalar va boshqa narsalarni olib tashlashni anglatadi. ma'lum bir bo'shliqdagi havodagi ifloslantiruvchi moddalar va xona ichidagi harorat, tozalik, ichki bosim va havo oqimi tezligi. Bu havo oqimining taqsimlanishi, shovqin tebranishi va yorug'ligi va ma'lum talablar doirasida statik nazoratga ega bo'lgan maxsus mo'ljallangan xona. Ya'ni, tashqi havo sharoitlari qanday o'zgarmasin, ichki makon dastlab o'rnatilgan tozalik, harorat, namlik va bosim xususiyatlarini saqlab qolishi mumkin. Hujayra zavodining C darajasidagi toza xona standartlari quyidagicha:
1. Toza ish joyidagi havo harorati 20-24 ℃
2 bo'lishi kerak. Toza ishlaydigan hududdagi havoning nisbiy namligi 45% -60%
3 bo'lishi kerak. Xonadagi havo almashinuvi soni: ≥25 marta/soat
4. Differensial bosim: C darajasidagi maydon tashqi havoga nisbatan ≥10Pa ni tashkil qiladi va bir xil darajadagi turli hududlar havo oqimi yo'nalishi bo'yicha
5 bo'yicha ma'lum bir bosim farqini saqlab turishi kerak. Yuqori samarali filtrning qochqinlarni aniqlash darajasi 99,97%
6 dan yuqori. Yoritish: >300lx-600lx
7. Shovqin: ≤75db (dinamik test)
Ishlab chiqarish muhiti uchun qat'iy talablarga qo'shimcha ravishda, cell zavodi mahsulotning sterilligini ta'minlash va hujayra o'sishi sharoitlari ehtiyojlarini qondirish uchun ishlab chiqarilgandan so'ng elektron nurli sterilizatsiyadan ham o'tadi.
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.
