Isitsha se-nitrogen esiwuketshezi yisitsha esikhethekile esisetshenziselwa ukugcina i-nitrogen ewuketshezi ukuze kulondolozwe amasampula ebhayoloji isikhathi eside
Uyazi ukuthi ungayisebenzisa kanjani kahle imigqomo ye-nitrogen ewuketshezi?
Kufanele kunakwe kakhulu i-nitrogen ewuketshezi uma kugcwaliswa, ngenxa yokushisa okuphansi kakhulu kwe-nitrogen ewuketshezi (-196℃), ukunganaki okuncane kungaholela emiphumeleni emibi, ngakho-ke yini okufanele inakwe lapho kusetshenziswa izitsha ze-nitrogen ewuketshezi?

Hlola ngemuva kokuthola iresidi nangaphambi kokusebenzisa
Isheke ngemuva kokuthola irisidi
Ngaphambi kokwamukela umkhiqizo nokuqinisekisa ukwamukelwa kwezimpahla, sicela uhlole abasebenzi bokulethwa ukuthi ngabe iphakheji yangaphandle inezimbobo noma izimpawu zomonakalo, bese uvula iphakheji yangaphandle ukuze uhlole ukuthi isitsha se-nitrogen esiwuketshezi sinazo yini izimbobo noma izimpawu zokushayisana. Sicela usayine izimpahla ngemva kokuqinisekisa ukuthi azikho izinkinga ngokubukeka.
Hlola ngaphambi kokusebenzisa
Ngaphambi kokugcwalisa isitsha se-nitrogen esiwuketshezi nge-nitrogen ewuketshezi, kubalulekile ukuhlola ukuthi igobolondo linamaqhubu noma izimpawu zokushayisana nokuthi ingabe i-vacuum nozzle assembly nezinye izingxenye zisesimweni esihle.
Uma igobolondo lonakele, izinga le-vacuum lesitsha se-nitrogen ewuketshezi lizoncipha, futhi ezimweni ezimbi kakhulu, isitsha se-nitrogen ewuketshezi ngeke sikwazi ukugcina izinga lokushisa. Lokhu kuzokwenza ukuthi ingxenye engenhla yesitsha se-nitrogen ewuketshezi ibe yiqhwa futhi kuholele ekulahlekelweni okukhulu kwe-nitrogen ewuketshezi.
Hlola ingaphakathi lesitsha se-nitrogen esiwuketshezi ukuze ubone ukuthi kukhona yini into yangaphandle. Uma kukhona umzimba wangaphandle, sisuse bese uhlanza isitsha sangaphakathi ukuze usivimbele ekugqwaleni.

Izinyathelo Zokuqapha Zokugcwalisa I-Nitrogen Emanzi
Uma ugcwalisa isitsha esisha noma isitsha se-nitrogen esiwuketshezi esingasetshenziswa isikhathi eside futhi ukuze ugweme ukwehla kwezinga lokushisa okusheshayo nokulimaza isitsha sangaphakathi futhi unciphise isikhathi sokusetshenziswa, kubalulekile ukusigcwalisa kancane kancane ngepayipi lokufaka. Uma i-nitrogen ewuketshezi igcwaliswe ingxenye yesithathu yamandla ayo, vumela i-nitrogen ewuketshezi ime inganyakazi esitsheni amahora angama-24. Ngemva kokuba izinga lokushisa esitsheni selipholile ngokuphelele futhi ibhalansi yokushisa isifinyelelwe, qhubeka nokugcwalisa i-nitrogen ewuketshezi ezingeni elidingekayo loketshezi.
Ungagcwalisi kakhulu i-nitrogen ewuketshezi. I-nitrogen ewuketshezi egcwele izopholisa ngokushesha igobolondo langaphandle futhi ibangele ukuthi i-vacuum nozzle ivuze, okuholela ekungasebenzi kahle kwe-vacuum ngaphambi kwesikhathi.

Ukusetshenziswa Nokugcinwa Kwansuku Zonke Kwesitsha Se-Nitrogen Esiwuketshezi
Izinyathelo zokuzivikela
·Isitsha se-nitrogen esiwuketshezi kufanele sibekwe endaweni enomoya omuhle futhi epholile, gwema ukukhanya kwelanga okuqondile.
·Ungasibeki isitsha endaweni enemvula noma enomswakama ukuze ugweme iqhwa neqhwa epayipini lentamo, ipulaki yesembozo nezinye izesekeli.
·Akuvunyelwe ngokuphelele ukuyitshekisa, ukuyibeka ngokuvundlile, ukuyibeka ibheke phansi, ukuyibeka ndawonye, ukuyigoqa, njll., kubalulekile ukuthi isitsha sigcinwe siqonde ngesikhathi sokusetshenziswa.
·Ungayivuli i-vacuum nozzle yesitsha. Uma i-vacuum nozzle yonakele, i-vacuum izolahlekelwa ukusebenza kwayo ngokushesha.
·Ngenxa yokushisa okuphansi kakhulu kwe-nitrogen ewuketshezi (-196°C), izinyathelo zokuzivikela ezifana nama-goggles namagilavu okushisa okuphansi ziyadingeka lapho kuthathwa amasampula noma kugcwaliswa i-nitrogen ewuketshezi esitsheni.
Ukugcinwa Nokusetshenziswa
·Izitsha ze-nitrogen eziwuketshezi zingasetshenziswa kuphela ukuqukatha i-nitrogen ewuketshezi, ezinye izinto eziwuketshezi azivunyelwe.
·Ungavali isivalo sesitsha.
·Uma uthatha amasampula, nciphisa isikhathi sokusebenza ukuze unciphise ukusetshenziswa kwe-nitrogen ewuketshezi.
·Kudingeka imfundo ejwayelekile yokuphepha yabasebenzi abafanele ukuze kugwenywe ukulahlekelwa okubangelwa ukusebenza okungafanele
·Ngesikhathi senqubo yokusetshenziswa, amanzi amancane azoqongelela ngaphakathi bese exutshwa namagciwane. Ukuze kuvinjelwe ukungcola ukuthi kungagqwali udonga olungaphakathi, isitsha se-nitrogen esiwuketshezi sidinga ukuhlanzwa kanye noma kabili ngonyaka.
Indlela Yokuhlanza Isitsha Se-Nitrogen Ewuketshezi
·Khipha ibhakede esitsheni, susa i-nitrogen ewuketshezi bese ulishiya izinsuku ezingu-2-3. Uma izinga lokushisa esitsheni lenyuka laya cishe ku-0℃, thela amanzi afudumele (ngaphansi kuka-40℃) noma ulixube nensipho engathathi hlangothi esitsheni se-nitrogen ewuketshezi bese ulisula ngendwangu.
·Uma kukhona izinto ezincibilikisiwe ezinamathela phansi kwesitsha sangaphakathi, sicela uzihlanze ngokucophelela.
·Thela amanzi bese ufaka amanzi amasha ukuze uwageze izikhathi eziningana.
·Ngemva kokuhlanza, beka isitsha se-nitrogen esiwuketshezi endaweni ecacile nephephile bese usenza some. Ukomisa umoya ngokwemvelo nokomisa umoya oshisayo kokubili kufanelekile. Uma lokhu kokugcina kwamukelwa, izinga lokushisa kufanele ligcinwe lingu-40℃ no-50℃ futhi umoya oshisayo ongaphezu kuka-60℃ kufanele ugwenywe ngokwesaba ukuthi kuzothinta ukusebenza kwethangi le-nitrogen eliwuketshezi futhi kunciphise isikhathi sokusebenza.
·Qaphela ukuthi phakathi nayo yonke inqubo yokukhuhla, isenzo kufanele sibe mnene futhi sihambe kancane. Izinga lokushisa lamanzi athululelwe akufanele lidlule ku-40℃ futhi isisindo sonke kufanele sibe ngaphezu kuka-2kg.
