Zovuta za laboratory (1)

Ntchito zotsatirazi ndizoletsedwa kwa omwe akhala mu labotale chaka chonse.Xiao Bian adazikonza lero ndikutumiza mwachangu kwa aliyense kuti aphunzire!

1. Bomba la firiji

Pa m'zigawo kapena dialysis, organic reagents ntchito ndi kuikidwa mu firiji lotseguka.Pamene mpweya wa organic ufika pachimake chovuta kwambiri, umayaka ndi spark yamagetsi pamene kompresa ya firiji yayamba.

Pa October 6, 1986, firiji m’malo ofufuza a Chinese Academy of Sciences inaphulika;

Pa December 15, 1987, firiji mu labotale ya Ningxia Academy of Agricultural Sciences inaphulika;

Pa July 20, 1988, firiji ya "Shasong" m'nyumba ya mphunzitsi wa Nanjing Normal University inaphulika.

M’zaka zochepa chabe, panali kuphulika kwa mafiriji oposa 10.Chomwe chinayambitsa ngoziyo sichinali khalidwe la furiji yokha, koma mankhwala monga petroleum ether, acetone, benzene ndi gasi wa butane anayikidwa mufiriji.Tikudziwa kuti kutentha mufiriji kumakhala kochepa.Ngati mufiriji mankhwala oyaka ndi ophulika okhala ndi mfundo yowira pang'ono ndi nsonga yonyezimira, amatenthetsa mpweya woyaka pansi pa kutentha kochepa.Ngakhale kapu ya botolo itapindika mwamphamvu, kutentha pang'ono kumapangitsa kuti chipolopolo cha botolo chichepetse, valavu ya gasi imamasula kapena ngakhale chipolopolo cha botolo chiphwanyike.Mpweya wosasunthika woyaka moto umasakanikirana ndi mpweya kupanga chisakanizo chophulika ndikudzaza mufiriji.Kuwala kwamagetsi komwe kumapangidwa pamene chosinthira kutentha (kapena zosintha zina zowongolera) zimatsegulidwa kapena kutsekedwa ndizosavuta kuphulika.Choncho, ogwiritsa ntchito firiji sayenera kusunga mankhwala mufiriji.

2. Thirani mowa ndi moto wotseguka

Tsegulani kupotoza koyaka kwa nyali ya mowa ndi pliers, ndikutsanulira mowa mu nyali ya mowa ndi dzanja limodzi, zomwe zingayambitse botolo lonse la mowa kuwotcha ndi kuphulika.

3. Bomba la nayitrogeni yamadzimadzi

Gwiritsani ntchito machubu a centrifuge otsekera magalasi ndi ma buckle kunyamula zitsanzo ndikuziyika m'matangi amadzi a nayitrogeni.Akatulutsidwa, katundu wa khoma la chitoliro asintha, ndipo sangathe kulimbana ndi kuwonjezereka kwa mpweya wa gasi, kapena kupanikizika kuli kosiyana pamene akuwotha mofulumira, kuchititsa kuphulika.

Choncho, anthu omwe amavala magalasi ali ndi ubwino - "Magalasi amoyo wautali!"

Othandizira omwe nthawi zambiri amatulutsa nayitrogeni wamadzimadzi azivala magalasi apulasitiki.

Zowopsa Mwachidule

Ngozi ya paumoyo: Mankhwalawa sangayaka komanso amapumira, ndipo kukhudzana ndi khungu ndi nayitrogeni wamadzimadzi kungayambitse chisanu.Ngati nayitrogeni wopangidwa ndi vaporization ndi wochuluka kwambiri pa kutentha kwabwinobwino, kupanikizika pang'ono kwa okosijeni mumlengalenga kumatsika, zomwe zimayambitsa anoxic asphyxia.

Njira zothandizira zoyamba

Pakhungu: Ngati pali chisanu, pitani kuchipatala.

Kukoka mpweya: choka pamalopo kuti ukhale ndi mpweya wabwino ndikupuma bwino.Ngati kupuma kuli kovuta, perekani mpweya.Ngati kupuma kwasiya, perekani mpweya wochita kupanga nthawi yomweyo ndipo funsani dokotala.

Njira zozimitsa moto

Zowopsa: Kukatentha, kukakamiza kwamkati kwa chidebecho kumawonjezeka, zomwe zingayambitse kusweka ndi kuphulika.

Njira yozimitsira: Chogulitsachi sichikhoza kuyaka, ndipo zotengera zomwe zili pamalo amoto ziyenera kusungidwa bwino ndi madzi a chifunga.The vaporization wa madzi asafe akhoza imathandizira ndi kupopera mbewu mankhwalawa madzi mu mawonekedwe a nkhungu, ndi madzi mfuti sadzawombera madzi asafe.

Kutayikira mwadzidzidzi chithandizo

Chithandizo chadzidzidzi: tulutsani mwachangu ogwira ntchito pamalo otayirapo ndi kupita kumalo olowera mphepo, kuwapatula, ndikuletsa kulowa.Ogwira ntchito zadzidzidzi azivala zopumira zokhala ndi mpweya wabwino komanso zovala zozizira.Osakhudza kutayikira mwachindunji.Dulani gwero lotayikira momwe mungathere.Pewani mpweya kuti usasonkhanitsidwe pamalo ochepera komanso kuphulika ukakumana ndi gwero la kutentha.Gwiritsani ntchito fani yotulutsa mpweya kuti mutumize mpweya wotuluka pamalo otseguka.Zotengera zomwe zikutuluka ziyenera kusamitsidwa bwino, kukonzedwa ndikuwunikiridwa musanagwiritse ntchito.

Kugwira ndi kusunga

Kusamala kwa opareshoni: chatsekedwa ntchito, kupereka zabwino zachilengedwe mpweya wabwino zinthu.Ogwira ntchito ayenera kuphunzitsidwa ndikutsata ndondomeko zoyendetsera ntchito.Ndikoyenera kuti ogwira ntchito azivala magolovesi otsimikizira kuzizira.Pewani kutuluka kwa gasi mumlengalenga wa malo ogwirira ntchito.Ma cylinders ndi zowonjezera ziyenera kusamaliridwa mosamala kuti zisawonongeke.Konzekerani zida zadzidzidzi kuti zitha kutayikira.

Chenjezo posungira: Sungani pamalo ozizira komanso olowera mpweya wabwino, ndipo kutentha sikuyenera kupitirira 50 ℃.

Chitetezo chaumwini

Chitetezo pamapumira: palibe chitetezo chapadera chomwe chimafunikira nthawi zambiri.Komabe, mpweya wa okosijeni ukakhala wochepera 19%, zopumira mpweya, zopumira mpweya ndi masks aatali achubu ayenera kuvala.

Chitetezo m'maso: valani chigoba chachitetezo.

Chitetezo m'manja: valani magolovesi otsimikizira kuzizira.

Chitetezo china: Pewani kutulutsa mpweya wambiri kuti mupewe kuzizira.
