Thaum npaj thiab tsim ib qhov kev sim, nws yog ib qho tseem ceeb kom paub txog kev nkag siab ntawm qee qhov kev sim qee yam kev tsim kho kom ua kom muaj kev sim zoo tsim kho. Yog li ntawd, cov ntsiab lus ntawm kev tsim ua kev sim siab li cas? Cov nram qab no yog cov ncauj lus kom ntxaws qhia rau koj los ntawm lub tsev tiag tiag.
Cov kev paub txog kev tshawb nrhiav hauv kev tshawb nrhiav mas yog cov hauv qab no:
1. Ua ntej pib ua haujlwm, nws yuav tsum to taub qhov twg qhov chaw siv roj, lub qhov dej thiab qhov hloov. Thaum tawm hauv qhov kev kuaj, nco ntsoov xyuas cov xim tha xim sab nrauv, tua cov dej, hluav taws xob, thiab cov roj hloov thiab xauv qhov rooj thiab lub qhov rais.
2. Thaum lub helium cylinder qhib, tus neeg teb xov tooj yuav tsum sawv ntawm lub qhov hluav taws xob ntawm lub tsheb tog raj kheej. Lub nkev roj nkev yuav tsum sawv ntsug thiab maj mam qhib lub raj mis valve. Cov nkev no yuav tsum raug kev nyuaj siab los ntawm lub siab ntsws nyem thiab yuav tsum tsis txhob muab pov tseg. Thaum hloov lub kaw lus siab tshuab raj, siv tes los yog tshwj xeeb tw caj npab, thiab tsis txhob siv cov cuab yeej xws li chisels thiab pliers tiv thaiv kev puas tsuaj rau lub valve. Kev siv cov nplaim hluav taws kub, cov nplaum tawg, chaw ua haujlwm muaj roj, ua haujlwm kom zoo, cov neeg ua haujlwm saib xyuas thiab siv. Cov roj hauv lub cylinder yuav tsum tsis txhob muab tag nrho tawm, tawm seem ntawm seem seem. Qhov siab qhov seem yuav tsum yog 2Kg · cm-2, thiab tsawg kawg tsis tshaj 0.5Kg · cm-2.
3. Thaum siv cov khoom siv hluav taws xob (xws li ncu, cov dej kub qhov kub qhov twg, qhov centrifuges, hluav taws xob fais fab, thiab lwm yam), hluav taws xob yuav tsum raug tiv thaiv kom nruj; thiab hloov hluav taws xob yuav tsum tsis txhob hloov nrog tes ntub los yog ntawm ob lub qhov muag. Ua ntej siv, ua ntej siv ib qho xaum xim ntsuam xyuas seb puas muaj cov khoom hluav taws xob tawm, yog tias cov khoom tso pa tawm, tsis tuaj yeem siv.
4. Yuav tsum tau txais kev saib xyuas tshwj xeeb thaum siv cov combustibles, tshwj flammables (xws li ether, acetone, ethanol, benzene, metallic sodium, etc.). Tsis txhob muab ntau rau ntawm lub rooj, tsis txhob tuaj yeem ua tus nplaim taws. Tsuas yog thaum deb ntawm qhov hluav taws kub, los yog tom qab hluav taws kub hnyiab lawm, cov kua hluav taws yuav raug muab pov tseg rau hauv qhov loj. Cov dej kub tsis tshua muaj peev xwm tsis tau tso kom sov rau ntawm qhov hluav taws kub thiab tsuas muaj cua sov los yog cov dej ntub dej uas siv cov kua qaub thim rov qab.
5, kev siv cov concentrated acid, concentrated alkali, yuav tsum tau xyuam xim kom tiv thaiv cov nchuav. Thaum siv lub raj dej los ntsuas cov reagents no, yuav tsum siv pob roj hmab thiab nws yuav tsum tsis txhob nqus ntawm lub qhov ncauj. Yog tias koj ua txhaum ntawm qhov kev ntsuas raug nplua los yog hauv av, koj yuav tsum siv cov ntaub ntub dej los so ntxuav. Yog tias kov cov tawv nqaij yuav tsum tau kho tam sim ntawd.
6, yog tias raug muab pov tseg ntau npaum li cas ntawm cov kua haus, nws yuav tsum raug kho raws li nram no:
(1) Tam sim ntawd kaw tag nrho cov hluav taws hauv tsev thiab hluav taws xob ua cua sov.
(2) Kaw qhov rooj, qhib qhov rais thiab qhov rais.
(3) Siv cov dej ntim kua nplaum los yog phuam, thiab muab cov kua tso rau hauv lub khob loj loj, ces muab tso rau hauv lub lam fwj.
7. Cov khoom ntawm cov khoom kub hnyav thiab cov khoom tawg (xws li ntses yas ntses, xim phosphor, thiab phom taub hau) yuav tsum tsis txhob muab hliv rau hauv cov thoob tsho los yog dab ntxuav tes thiab yuav tsum muab ntim rau hauv cov thawv rau khoom.
8, khib nyiab, qog kua qaub thiab lub hauv paus muaj zog tsis tuaj yeem ncaj qha rau hauv lub dab dej, yuav tsum tau diluted, ces nchuav hauv lub dab ntxuav tes, thiab siv ntau qhov dej los ntxuav lub dab dej thiab cov kav dej.
9, cov tshuaj lom yuav tsum tau ua raws nraim li kev kuaj xyuas kev pom zoo rau kev pom zoo tom qab kev ntsuam xyuas thiab kev pom zoo, kev siv cov kev ua haujlwm nruj heev, tsim nyog ua tom qab siv.
10. Thaum ua hauj lwm nrog roj da dej, yuav tsum tau saib xyuas kom paub tseeb tias qhov ntsuas kub tas li ntsuas nrog tus pas ntsuas kub thiab qhov ntsuas kub tsis tshaj qhov ntsuas kub ntawm cov roj.
