Yas Beaker / Ntsuas khob

Yas Beaker / Ntsuas khob

Siv dav hauv kev sim thiab kev tshawb fawb hauv chemistry, biology, tshuaj, thiab lwm yam.

Khoom nta:

① ruaj khov puag, tsis yooj yim rau ntxeev

② Cov cim meej meej rau kev ntsuas kua yooj yim

③ Kub kub thiab corrosion kuj
④ Tsis yooj yim tawg

⑤ Yooj yim los ntxuav thiab tua kab mob

⑥ Thickened phab ntsa rau lub cev muaj zog thiab ua haujlwm kub zoo
⑦ Muaj nyob rau hauv ob txoj kev xaiv: nrog kov thiab tsis muaj kov

Cov kev ceev faj:

① Zam kom tsis txhob kub siab: Tsis txhob tso lub beaker ncaj qha mus rau siab - qhov chaw kub xws li nplaim taws lossis hluav taws xob rauv taws kom tsis txhob deformation lossis tawg. Yog xav tau cua sov, siv cov cua kub tsis ncaj xws li da dej los yog da dej roj.
② Tshawb xyuas kev ncaj ncees: Ua ntej siv, ua tib zoo xyuas lub beaker rau cov kab nrib pleb, khawb, lossis deformation kom ntseeg tau tias nws muaj kev ncaj ncees thiab tiv thaiv kev tawg thaum lub sijhawm sim.
③ Chemical compatibility: Nkag siab txog cov khoom ntawm cov tshuaj uas xav tau rau kev sim kom paub tseeb tias lawv sib haum nrog cov yas beaker thiab tsis txhob xeb ntawm lub beaker los ntawm cov tshuaj.
④ Kov nrog kev saib xyuas: Thaum lub sijhawm ua haujlwm, tuav lub beaker maj mam kom tsis txhob muaj kev sib tsoo hnyav thiab txo qhov kev pheej hmoo ntawm kev tawg.
⑤ Cov cuab yeej tiv thaiv tus kheej: Hnav cov cuab yeej tiv thaiv tus kheej tsim nyog, xws li hnab looj tes thiab tsom iav kev nyab xeeb, txhawm rau tiv thaiv cov tshuaj lom ntawm daim tawv nqaij lossis qhov muag thiab ua kom muaj kev nyab xeeb ntawm kev sim.
