Izinkinga zokuphepha kokudla zihlobene nempilo yawo wonke umuntu, ngakho-ke bekulokhu kugxilwe kakhulu emphakathini. Ikakhulukazi eminyakeni yamuva nje, ngezimo zezinto ezibonakalayo zabantu kanye nokuthuthuka okuqhubekayo kwezindinganiso zokuphila, isidingo sokuhlolwa kokudla siqhubeke nokukhula.

Eqinisweni, umsebenzi wokuhlola ukudla kanye nokulandelela ukudla ngokuvamile uhlukaniswe ngezigaba ezimbili: esinye singesezinto zokuhlanzeka, kanti esinye singesezinto ezisezingeni eliphezulu.

Kodwa-ke, kungakhathaliseki ukuthi hlobo luni, kuyadingeka ukuqinisekisa ukunemba kwemiphumela yokuhlolwa, ngaphandle kwalokho ngeke kwenzeke ukuthuthukisa ukuhlaziywa okwengeziwe kanye nokuboniswa. Ngaphezu kwalokho, ngaphandle kwamasampula azohlolwa, uma kunenkinga ngamanzi, ama-reagent, noma izitsha zengilazi enkambisweni yokuhlolwa kokudla elabhorethri, khona-ke ubuqiniso bemiphumela yokuhlolwa kokudla buzobuzwa.

Izinyathelo eziyisisekelo zokuhlola ukuphepha kokudla

Ukuhlolwa kokuphepha kokudla ukusetshenziswa kwemibono eyisisekelo nezindlela zobuchwepheshe okuhlanganisa i-physics, i-chemistry, i-biology kanye neminye imikhakha ukuhlola, ukunquma nokuhlaziya izithako eziyinhloko, isimo, kanye nesimo se-microbiological sezinto zokusetshenziswa, izinto ezisizayo, imikhiqizo eqediwe, imikhiqizo eqediwe, kanye nemikhiqizo engaphansi. Izinyathelo eziyisisekelo zifaka:

① Qoqa amasampula: qinisekisa inhloso yokuhlolwa, wakhe ububanzi bokuhlolwa kanye nezinto ezithile zokusampula.

② Ukulungiswa kwamasampula: Faka amasampula athathwe emabhodleleni esampula ahlanzekile, bese uphawula amabhodlela esampula ngokwezinombolo ezilandelanayo kumasampula. Amamaki enziwe kufanele akwazi ukuhlonza isimo sokuhlolwa kwesampula. Lungiselela ukucubungula isampula kusengaphambili ukuze ulungiselele ijika lesampula kanye nesisombululo sokuthola isampula.

③Amasampula okuhlola: Ngosizo lwezinsimbi ezihlobene, ama-reagent noma izixazululo ezijwayelekile kanye nesisombululo sokuhlola kuzohlolwa ngesikhathi esifanayo. Ngemva kokubala imiphumela yokuhlolwa nokuthola amarekhodi okuqala, umbiko wokuhlola ungabhalwa.

Kule nqubo, amanzi, izinto zokuvuselela, kanye nezinto zengilazi kudlala indima ehlukene.

Amanzi: Amanzi ahlanzekile alungiselelwe ngokukhethekile kanye namanzi acwengekile kuyisici esibalulekile enkambisweni yokuhlola ukudla. Ezintweni zokuhlola ezijwayelekile, njengokulungiswa kwe-reagent kanye nesigaba senqubo yokuhlola, sebenzisa amanzi ajwayelekile acwengekile njengokukhetha okuyinhloko. Kubalulekile ukuqaphela ukuthi lapho kwenziwa ukunqunywa kwezakhi ezithile zokulandelela, ukuzwela kwamanzi acwengekile kudinga ukucutshungulwa futhi ngaphambi kokuba angene esinyathelweni esilandelayo sokuhlolwa kokudla.

Ama-reagent: Ama-reagent esivivinyweni kufanele asetshenziswe ngokufanele ukuze athinte ngqo isayensi kanye nokunemba kwemiphumela yokuhlolwa kokudla. Kufanele kunakwe ngokukhethekile isikhathi sokuphelelwa yisikhathi sama-reagent amakhemikhali. Ukuhlushwa kanye nekhwalithi kudinga ukulinganiswa njalo, futhi ukusetshenziswa kwama-reagent amakhemikhali aphelelwe yisikhathi akuvunyelwe, ngaphandle kwalokho kuzothinta ukunemba komphumela wokuthola. Ngaphezu kwalokho, ukufaka i-tit yesisombululo ngokuhambisana nezincazelo ezifanele kunganciphisa kakhulu ingozi yokwehluleka kwama-reagent.

Izitsha Zengilazi: Njengamanje, amabhodlela engilazi noma imikhiqizo ye-polyethylene isetshenziswa kakhulu ezitsheni zokuhlola ukudla, ezingasetshenziswa ukugcina izidakamizwa, ukuthutha izidakamizwa, kanye nemithi yokuhlola. Njengezitsha zokuhlola, ama-beakers, ama-volumetric flasks, ama-weighbor flasks kanye nama-Erlenmeyer flasks. Kodwa into ebaluleke kakhulu ukuqinisekisa ukuthi ukuhlanzeka kanye nokumelana nokuvuza kwalezi zitsha zengilazi kuhambisana nezindinganiso kanye nemininingwane efanele. Ngakho-ke, isitsha somkhiqizo wokuhlola kumele sihlanzwe kahle ngaphambi kokusetshenziswa ukuqinisekisa ukuthi akukho ukungcola okusele. Indima yezitsha zengilazi cishe iphakathi kwezici ezibaluleke kakhulu zokuhlolwa kokudla.

Yikuphi ukungcola okusele okuvame ukwenzeka ekuhlolweni kokudla? Ingabe kungahlanzwa?

Noma yimuphi umsebenzi wokuhlola ukudla uzokhiqiza cishe noma kancane izinto ezingcolisayo ezitsheni zengilazi, njengezitshalo zamagciwane, izinsalela zezibulala-zinambuzane, i-formaldehyde, izinsimbi ezisindayo, ama-protease, izithasiselo zokudla, izithasiselo zokudla okunempilo, izinsalela ze-reagent ekuhlolweni kokuhlola, i-activator yokuwasha ngesikhathi sokuhlanza, njll. Ngakho-ke, izitsha zengilazi kumele zihlanzwe ngaphambi kokusetshenziswa okulandelayo. Kodwa le nqubo ayigcini nje ekuhlanzweni ngesandla. Njengoba sibheka inani elikhulu, ukuhlukahluka, ukuntuleka kwabasebenzi, kanye nesikhathi esinzima, ake sibheke izinzuzo zalokhu.umshini wokuwasha elebhukukhiqizwe yi-Hangzhou Xipingzhe Instruments Technology Co.,Ltd? Isibonelo, umphumela wokuhlanza awugcini nje ngokuthembeka nokunembile kunokuhlanza ngesandla, kodwa futhi uyaqoshwa, uyaqinisekiswa, futhi uyaphindaphindwa! Kuhlanganiswe nobuhlakaniumshini wokuwasha izingilazi ozenzakalelayoukulawula inqubo yokuhlanza, kusiza kakhulu ekuthuthukiseni ukusebenza kahle kokuhlolwa kokudla kanye nokuqinisekiswa kokuphepha.

Ngamafuphi, ukuthuthukisa ukunemba kwemiphumela yokuhlolwa kokudla yisona siqondiso imboni yokuhlola ukudla eqhubeka nokusifinyelela. Ukuze imiphumela yokuhlola ukuphepha kokudla ihambisane nedatha yangempela yokuhlolwa, noma yiliphi lamanzi, ama-reagent, kanye nezitsha zengilazi kubalulekile. Ikakhulukazi, ukuhlanzwa kwe-umshini wokuwasha izingilaziingathuthukisa njalo ukuhlanzeka ukuze ihlangabezane nezindinganiso ezilindelekile zokuhlolwa kokudla. Kungale ndlela kuphela lapho ingasetshenziswa ngempumelelo njengesisekelo sokubhekisela esiqondile nesifanele. Ngithemba ukuthi abahloli bokudla bazokhumbula lokhu, futhi bangavumeli umsebenzi wokuhlola ukuphepha kokudla uphele noma wonakaliswe ngenxa yokuhlanza izitsha zengilazi.
