Isiko lamaseli ngumsebenzi obucayi kakhulu. Kuyadingeka ukuqinisekisa ukuthi imvelo ayinyumba futhi ayinabo ubuthi, futhi izinga lokushisa lifanelekile, kanye nokudla okwanele. Izinto ezisetshenziswa amaseli ziyisidingo sokuqala sokufeza lezi zimo ezifanele, futhi ukukhetha nokusetshenziswa kwazo kubaluleke kakhulu. I-fektri yamaseli isetshenziswa okuvamile emsebenzini omkhulu wamaseli. Yiziphi izici zempahla yayo yokukhiqiza?
Izisetshenziswa zemboni yamaseli ngokuvamile ziyi-polystyrene yezinga lezokwelapha (isiNgisi: I-Polystyrene, ebizwa ngokuthi i-PS), esetshenziswa kakhulu ukwenza amabhodlela ezokwelapha, isirinji. amathreyi nezinto zokupakisha. I-copolymer yayo ene-diene ne-acrylonitrile yaziwa kakhulu ngokuthi yi-l1#iS resin. Inamandla amahle kakhulu wemishini nokusebenza kokucubungula. Ingasetshenziselwa ukulungisa amagobolondo ezinso zokwenziwa zohlobo lwe-adsorption. Ingenziwa ibe yi-porous carbonized adsorption resin ukuze kukhishwe izinto ezinobuthi egazini lesiguli, njengezidakamizwa ezeqile namanye amasosha omzimba angama-pathogenic kanye ne-immune complexes.
I-Polystyrene impahla inalezi zimpawu ezilandelayo:
1. Ukuthungwa kuqinile futhi amandla omthelela aphansi; ukucushwa okungahleliwe kwe-polystyrene kunokucwebezela okuhle, ukudluliswa kokukhanya okuphezulu nemibala emihle.
2. Izinga lokushisa elithambile lingu-80°C. Ngaphansi kuka-80°C iqinile njengengilazi. Ngaphezu kuka-80°C iba yinto ethambile. Inezici ezifana nerabha. Gwema ukuyisebenzisa emazingeni okushisa aphezulu.
3. Ukusebenza okuhle kokubumba, ngaphakathi kwebanga lokushisa elisetshenziswayo, umkhiqizo oqediwe une-shrinkage encane kanye nokuguqulwa kanye nobukhulu obuzinzile; ukumelana kahle kwamanzi, ukuzinza kwamakhemikhali kunciphisa ngokunyuka kwezinga lokushisa; ngokugxila okuthile kwama-acids angaphili, ama-asidi aphilayo, izixazululo zikasawoti kanye nama-alkali , Utshwala, amafutha emifino, njll. anokumelana okuhle, futhi kancane kancane azophenduka aphuzi, ahlakazeke futhi aqhekeke lapho ebekwe elangeni isikhathi eside.
4. Ukuthintana namafutha kanye nama-ejenti okulawula izinambuzane kuvame ukubonakala kuqhekeka, kushintshe umbala futhi kuncibilike okunamathelayo, futhi kujwayele ukuguga nokubaphuzi ngaphansi kokukhanya, umoya-mpilo, nokushisa.
5. Incibilika kalula kuzincibilikisi zemvelo njenge-chloroform, i-dichloromethane, i-toluene, i-butyl acetate, njll. Gwema ukuthintana nezincibilikisi ezingenhla ngesikhathi sokugcina.
Okungenhla kumayelana nezici zezinto ezisetshenziswa ku-imboni yeselula. I-Polystyrene iyinto esetshenziswa kakhulu ezintweni ezisetshenziswa amaseli. Isibonelo, amapuleti e-cell culture, amaflask e-cell culture, amapuleti e-elisa noma amapuleti e-chemiluminescent azosebenzisa le nto ukuze kuqinisekiswe ukuthi ihlangabezana nezidingo zokukhula kwamaseli.
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.
