YYT-T453 Zovala zoteteza zotsutsana ndi asidi ndi alkali
Chida ichi chapangidwa mwapadera kuti chiyese mphamvu ya nsalu zoteteza nsalu zochotsa madzi zomwe zimateteza ku asidi ndi alkali.
1. Thanki yowonekera bwino ya semi-cylindrical plexiglass, yokhala ndi mainchesi amkati a (125±5) mm ndi kutalika kwa 300 mm.
2. M'mimba mwake mwa dzenje la singano ndi 0.8mm; nsonga ya singano ndi yathyathyathya.
3. Dongosolo lojambulira lokha, jakisoni wopitilira wa reagent wa 10mL mkati mwa masekondi 10.
4. Nthawi yodziwira yokha ndi dongosolo la alamu; Nthawi yoyesera chiwonetsero cha LED, kulondola 0.1S.
5. Mphamvu: 220VAC 50Hz 50W
GB24540-2009 "Zovala zoteteza, zovala zoteteza mankhwala okhala ndi asidi"
1. Dulani pepala losefera lamakona anayi ndi filimu yowonekera bwino iliyonse yokhala ndi kukula kwa (360±2)mm×(235±5)mm.
2. Ikani filimu yowonekera bwino yoyezedwa mu thanki yolimba yowonekera bwino, iphimbeni ndi pepala losefera, ndipo imamatirane bwino. Samalani kuti musasiye mipata kapena makwinya, ndipo onetsetsani kuti malekezero apansi a mpata wolimba wowonekera bwino, filimu yowonekera bwino, ndi pepala losefera ndi osalala.
3. Ikani chitsanzo pa pepala losefera kuti mbali yayitali ya chitsanzo igwirizane ndi mbali ya payipi, pamwamba pa payipi pakhale pamwamba, ndipo mbali yopindidwa ya chitsanzocho ili 30mm kupitirira kumapeto kwa payipi. Yang'anani chitsanzocho mosamala kuti muwonetsetse kuti pamwamba pake pakugwirizana bwino ndi pepala losefera, kenako konzani chitsanzocho pa payipi yolimba yowonekera bwino ndi chomangira.
4. Yesani kulemera kwa beaker yaying'ono ndikulemba ngati m1.
5. Ikani beaker yaying'ono pansi pa m'mphepete mwa chitsanzo kuti muwonetsetse kuti ma reagents onse omwe akuyenda kuchokera pamwamba pa chitsanzo asonkhanitsidwa.
6. Tsimikizirani kuti chipangizo chowerengera nthawi cha "nthawi yoyesera" chomwe chili pa bolodi chayikidwa pa masekondi 60 (chofunikira chokhazikika).
7. Dinani "chosinthira magetsi" pa panelo mpaka pamalo a "1" kuti muyatse mphamvu ya chipangizocho.
8. Konzani reagent kuti singano yobayira ilowe mu reagent; dinani batani la "aspirate" pa bolodi, ndipo chidacho chidzayamba kugwira ntchito kuti chitulutse.
9. Pambuyo poti madzi alowetsedwa, chotsani chidebe cha reagent; dinani batani la "Inject" pa panel, chidacho chidzalowetsa reagents zokha, ndipo nthawi yoyezera idzayamba nthawi; jakisoniyo imatha patatha masekondi pafupifupi 10.
10. Pambuyo pa masekondi 60, cholemberacho chidzachenjeza, kusonyeza kuti mayeso atha.
11. Dinani m'mphepete mwa mpata wolimba wowonekera bwino kuti chogwirira ntchito chomwe chili m'mphepete mwa chitsanzo chichotsedwe.
12. Yesani kulemera konse kwa m1/ kwa zinthu zogwiritsidwa ntchito zomwe zasonkhanitsidwa mu beaker yaying'ono ndi chikho, ndikulemba detayo.
13. Kukonza zotsatira:
Chizindikiro cha mankhwala oletsa kutupa kwa madzi chimawerengedwa motsatira njira iyi:
I- chizindikiro choletsa madzi,%
m1 - Kulemera kwa beaker yaying'ono, mu magalamu
m1' - unyinji wa ma reagents omwe asonkhanitsidwa mu beaker yaying'ono ndi beaker, mu magalamu
m - kulemera kwa reagent komwe kunagwera pa chitsanzo, mu magalamu
14. Dinani "chosinthira magetsi" pamalo a "0" kuti muzimitse chidacho.
15. Mayeso atha.
1. Pambuyo poyesa, ntchito zotsukira ndi kuchotsa madzi otsala ziyenera kuchitika! Mukamaliza gawo ili, ndi bwino kubwereza kuyeretsa ndi chotsukira.
2. Asidi ndi alkali zonse zimawononga. Ogwira ntchito yoyesera ayenera kuvala magolovesi osapsa ndi asidi/alkali kuti apewe kuvulala.
3. Mphamvu ya chipangizocho iyenera kukhala yokhazikika bwino!
