Cov iav Petri cov tais diav feem ntau yog siv cov hlab ntsha hauv cov chaw kuaj mob rau kev cog qoob loo ntawm cov kab mob lossis cov hlwb.

Lub melting point ntawm iav kab lis kev cai tais diav feem ntau ntog nyob rau hauv thaj tsam ntawm 500 mus rau 1500 degrees Celsius; qhov tshwj xeeb melting point nyob ntawm lub iav qhov muaj pes t...

Cov khoom siv tseem ceeb siv rau cov iav raj yog silicate iav, uas yog tsim los ntawm melting raw cov ntaub ntawv-xws li silica xuab zeb (nws lub ntsiab tivthaiv yog silicon dioxide), dej qab zib t...

Cov iav tsom iav yog cov khoom tawg yooj yim; yog li ntawd, lawv cov khoom xa tuaj yuav tsum muaj cov txheej txheem ntim tshwj xeeb.

Cov iav xeem raj tuaj nyob rau hauv ntau yam ntawm specifications thiab qhov ntev; Yog li ntawd, xaiv qhov tsim nyog loj thiab hom raws li qhov kev sim tshwj xeeb yog qhov tseem ceeb.

Raws li ib qho cuab yeej tseem ceeb hauv ob qho tib si hauv chaw kuaj mob thiab kev kho mob, kev tsim cov iav kuaj cov raj yog cov txheej txheem uas ib txhij sib sib zog nqus thiab nyuaj.

Rau kev saib xyuas niaj hnub, cov iav ntsuas cov raj yuav tsum tau yaug tam sim nrog dej huv tom qab siv.

Thaum siv cov iav kuaj cov raj hauv chav kuaj, nws yog ib qho tseem ceeb kom ua raws li cov txheej txheem tseem ceeb thiab kev ceev faj txog kev nyab xeeb.

Raws li ib qho ntawm cov khoom siv hauv chav kuaj iav, cov iav ntsuas cov raj ua lub luag haujlwm tseem ceeb hauv kev tshawb fawb, kev kawm, thiab lub neej txhua hnub.

Ua ntej siv, tshuaj xyuas kev ncaj ncees ntawm lub cev pipette; Cov ntaub ntawv los ntawm Taizhou tus thawj coj saib xyuas cov xwm txheej hauv 2023 qhia tias qee yam khoom tsis muaj npe yuav tsum t...

Yas droppers feem ntau yog tsim los ntawm polyethylene (PE) los yog polypropylene (PP).
