Media bottleiyisitsha sokugcina i-serum, ngokuvamile eyenziwe nge-PET noma i-PETG material ngenqubo yokufutha ngomjovo elula. Okuphakathi wumsoco odingekayo ekukhuleni kwamangqamuzana. Ngokomthombo wawo, ihlukaniswe yaba i-synthetic medium kanye ne-natural medium, kokubili okungagcinwa emabhodleleni emidiya.
Imvelo yemvelo:
Indlela yemvelo esetshenziswa kakhulu i-serum, i-calf serum. I-Serum iqukethe izici ezihlukahlukene zokukhula kwamaseli, izici ezikhuthaza ukunamathela kanye nezinto zazo ezisebenzayo eziningi. Uma isetshenziswa ihlanganiswe ne-synthetic medium, amaseli anganda futhi akhule kahle. I-Serum idinga ukugcinwa emabhodleleni emidiya akhethekile ku-5°C kuya -20°C.
Synthetic medium:
Synthetic medium yakhiwe ngokuqinile ngokohlobo nenani lezinto ezidingwa amaseli. Kunezinhlobo eziningi nezingxenye ezaziwayo, ezisiza ukulawulwa kwezimo zokuhlola. Iqukethe ama-carbohydrate, ama-amino acid, amafutha, usawoti we-inorganic, amavithamini, izakhi zokulandelela kanye nezici zokukhula kwamangqamuzana. Nokho, uma kuqhathaniswa nendawo yemvelo, ezinye izingxenye zemvelo ezingaziwa azikwazi ukuthathelwa indawo yizakhi zamakhemikhali ezaziwayo. Ngakho-ke, indlela eyisisekelo yokwenziwa esetshenziswa kusiko lamaseli kumele futhi yengeze inani elithile lezingxenye zemvelo ezimaphakathi ukuze kunqobe isiko lokwenziwa. Umkhuba ovame kakhulu ukufaka i-calf serum.
Ukwakheka kwebhodlela lemidiya kuyisikwele, kulula ukulibamba, alikwazi ukumelana nokugqwala kwe-asidi ne-alkali, izinga lokushisa le-embrittlement lingu-70 °C, futhi lisenokuqina okuthile. ngo -30 °C. Kuyisitsha esihle sokupakisha, kokubili imidiya yemvelo neyokwenziwa ingagcinwa ebhodleleni lemidiya.
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.
