Ngokuthuthuka okuqhubekayo kwe-biotechnology, ukusebenza kahle okuphezulu erlenmeyer shake flasks kudlala indima ebalulekile ngokuya ngesiko lamaseli. Isiko leseli lidinga indawo ethile, futhi izidingo zezinto ezisetshenziswa amaseli ziphezulu uma kuqhathaniswa. Ngakho-ke iyiphi impahla esetshenziselwa i-erlenmeyer shake flask esebenza kahle kakhulu futhi yiziphi izici zayo?
Into esetshenziselwa ukusebenza kahle kakhulu kwamaflaski e-erlenmeyer shake ngokuvamile i-PETG, okuyi-amorphous copolyester esobala. Imikhiqizo yayo inokucaca okuphezulu. Izindlela zendabuko zokukhipha amabhamuza, umjovo, igalelo, nezindlela zokubumba amabhamuza zingasetshenziswa. Isetshenziswa emakethe yezinto zeshidi, ifilimu yokushwabana esebenza kahle kakhulu, ibhodlela nezinto ezinephrofayili, futhi inezici ezilandelayo:
1. Ukusebenza kwe-Thermoforming
PETG amashidi kulula ukukhiqiza imikhiqizo enomumo oyinkimbinkimbi kanye nezilinganiso ezinkulu zokunwebeka. Ngaphezu kwalokho, ngokungafani nebhodi le-PC kanye ne-acrylic eguquliwe nomthelela, leli bhodi alidingi ukuthi lomiswe ngaphambili ngaphambi kwe-thermoforming. Uma kuqhathaniswa ne-PC board noma i-acrylic, umjikelezo wayo wokubumba mfushane, izinga lokushisa liphansi, futhi isivuno siphezulu.
2. Ukuqina
Ishidi elikhishiwe le-PETG livame ukuqina izikhathi ezingu-15 kuya kwezingu-20 kune-acrylic evamile futhi izikhathi ezi-5 kuya kweziyi-10 ziqine kune-acrylic eguquliwe. Ishidi le-PETG linomthamo owanele wokuzala ngesikhathi sokucubungula, ukuthuthwa nokusetshenziswa, okusiza ukuvimbela ukuqhekeka.
3. Ishidi lokumelana nesimo sezulu
PETG linikeza ukumelana nesimo sezulu esihle kakhulu. Ingakwazi ukugcina ukuqina komkhiqizo futhi ivimbele ukuphuzi. Iqukethe izinto zokumunca i-ultraviolet, ezinganwetshwa ndawonye zibe ungqimba oluvikelayo ukuze kuvikelwe ibhodi emiphumeleni eyingozi yemisebe ye-ultraviolet.
4. Kulula ukucutshungulwa
PETG ishidi lingasaha, lisikwe, libhojwe, libhotshwe, lisikwe, liqhunyiswe, ligaywe futhi libe makhaza ngaphandle kokuphuka. Ukuklwebheka okuncane ebusweni kungaqedwa ngesibhamu somoya oshisayo. I-solvent bonding nayo iwumsebenzi ovamile. Kulula ukusetshenzwa kune-acrylic evamile, i-acrylic eguquliwe eguquliwe noma ibhodi le-PC, futhi ingacutshungulwa ukuze igcwale, i-electroplating, ugesi omile nokunye ukucutshungulwa.
5. I-Chemical resistance
PETG sheet ingamelana nezinhlobonhlobo zamakhemikhali nama-ejenti okuhlanza avamile.
6. Ukuvikelwa komnotho kanye nemvelo
PETG sheet substrates zonke izinto ezihambisana nemvelo, ezihlangabezana nezidingo zokuphatha ukuxhumana nokudla. Ishibhile kunebhodi le-PC, futhi ihlala isikhathi eside kunebhodi le-PC.
Lokhu okungenhla yizimpawu ezibonakalayo zokusebenza kahle kakhulu erlenmeyer shake flasks. Lezi zici ze-PETG zihlangabezana nezidingo zobuchwepheshe be-cell culture yezinto ezisetshenziswayo, futhi iyikhwalithi ephezulu ye-polymer material.
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.
