Iityhubhu zovavanyo ze-COD: Imiyalelo kunye nesikhokelo sokuthatha amanyathelo

I-aperture yombala omkhulu wokugaya kwimakethi yenziwa kwi-16mm, kunye nokunyamezelana kwebhotile yeglasi ye-tube ubukhulu becala i- ± 0.2mm, ke ± 0.2mm.

Ukuphakama kweI-tube yovavanyoIngama-90, 100, 110, 125, 13, 150mm. Ngokutsho kwenqanaba le-Regal eyahlukeneyo yomenzi ngamnye, ukuphakama kwahlukile. Phakathi kwabo, ezona zisetyenziswayo zisetyenziswa yityhubhu yovavanyo lwe-100mm.

Izixhobo zovavanyo ze-COD

Izixhobo zeItyhubhu ye-CODzihlala ziphantsi kwe-borosililicate ephantsi, i-borosililicate, kunye ne-borosilicicate ephezulu. Bangasetyenziswa xa kufuneka amabala. Xa kunomgangatho wamanzi omgangatho kunye nombala kuyafuneka, izinto ezikhethiweyo azithathi hlangothi.

Zintathu iindidi zezixhobo zesiciko: I-white polypropylene yokufumana ixesha elinye; I-polycanere ye-polycarcate yokusebenzisa okuphindaphindiweyo; I-Reld Funolin Retin yokusetyenziswa okuphindaphindiweyo kwezityholo zovavanyo ngaphezulu kwe-110mm.

Ngolwazi oluthe kratya malunga neetyhubhu zovavanyo lwe-COD kunye nezicelo zazo kuhlalutyo lwamanzi, zibhekisa kweli nqaku:"Indlela i-COD ye-COD isetyenziswa ngayo kuhlalutyo lwamanzi."

Ukugaya Amanyathelo okhuseleko lwe-tube

1. Sebenzisa isixhobo sokugaya esihambelana ne-tube. I-Bottoms ejikelezileyo ihambelana nezixhobo ezijikelezayo ezijikelezileyo, kwaye iibhotile ezinamafutha zihambelana nezixhobo zokuganga. Ngaphandle koko, ukufudumeza okungalinganiyo kuya kubangela ukuba ityhubhu inyuke. Xa ibeka ityhubhu yovavanyo, kufuneka ibekwe kancinci ukuphepha ukugqabhuka okubangelwa kukungqubana kobundlobongela kwetyhubhu yokugaya kunye nomngxunya wokugaya. Ngokwamava adlulileyo, iityhubhu zokugaya ziqhuma ngenxa yokusebenza okungafanelekanga.

2. Kunqande ukusebenzisa ii-tuby ze-tubes kunye neebds ezinentambo ezimdaka. I-Missisches ayiyi kutywina kwaye ivule. Kuxhomekeka ikakhulu ukuba igudileyo xa ijijekile. Ukugudisa kwaye kuyagudisa kwaye isiciko asibuhlungu kakhulu sokufezekisa iimfuno.

3. Kuphephe ukoyikwa kakhulu. Iityhubhu kunye ne-tubes ziya kuba nokutyibilika xa kuhliswa omnye komnye. Ukucoca ibhotile kulula ukubangela ukukhulisa. I-scratchects ziimpawu ezibuthathaka zamandla etyhubhu.

4. Kunqande ukusebenzisa iibhotile ezonakalisiweyo kunye nezibuko. Ngenxa yokungenelela kwencwadana yezikhokelo ngexesha lokuhamba kunye nemveliso, iimveliso ezinjalo azinakuphepheka. Sukusebenzisa iibhotile kunye nezibuko ezineziphene.

5. Ungabizi ngqo iisampulu zamanzi. Kuya kufuneka ukuba ube neendawo eziguquguqukayo. Indawo yokubila yamanzi iphantsi kakhulu. Elona ninzi lamanzi, kokukhona ingxinezelo kwibhotile iya kuba, kwaye isiciko asiyi kuba nakho ukubamba. Ukuba ufuna ukugaya iisampulu zamanzi ezingaphezulu, nceda usebenzise isiciko esinganyangekiyo kwaye sibuhlungu.

6. Ukuthatha isigqibo sesalathiso se-COD kunye neesampulu zamanzi njengomzekelo, kuba ezinye iindawo zokuhlala ze-sulfuric kufuneka zongezwe kwisampulu yamanzi, ukuba ingabangela isampulu ye-sulfuric acid kwaye ibangele ukubamba ityhubhu. Ke ngoko, isampulu yamanzi kufuneka idityaniswe nokunyaniseka ngaphambi kokugaya ukuthintela ityhubhu yokugaya ukuba ifike kwakhona.

Ukhetho lokuthelekisa

1. Shake kakuhle ngaphambi kokuba uthelekise. Ngaphambi kokubeka ityhubhu yovavanyo kwifotometer, sula ityhubhu yovavanyo icocekile ngendwangu yetyhefu yovavanyo.

2. Khetha isixhobo esilawulwayo kunye nesixhobo sombhobho ngempazamo encinci ukunqanda iimpazamo ezininzi ezibangelwa ngabasebenzi nezixhobo.

3. Ukuba kukho isikrweqe, musa ukulungelelanisa umphezulu wokukrakra kunye nendawo yokuthelekisa.

I-4. Kumgangatho wokugaya i-SpeestRophotometry, imfuneko ye-tube ye-lemidlalo kukuba impazamo ye-Absorbeth iphakathi kwe-± 0.005, i-tubs ye-Bible ye-Bibt kufuneka ibe ngaphakathi kwinqanaba lemposiso kangangoko kunokwenzeka. Ukuba i-20% yeetyhubhu kwi-batch igqitha kuluhlu lwemposiso, iityhubhu zemifanekiso ye-batch aziqinisekanga.

5. Nceda usebenzise amanzi acocekileyo ukuze avavanye impazamo ye-tube.

[Iingcebiso zothelekiso lwe-Familmitic)

Xa ithelekiswa ne-Famimarictric Thaimen, musa ukuvavanya enye kuphela, kuba kulula ukuba neempazamo kwezona xabiso ziphezulu kunye nexabiso elincinci, okanye kusenokwenzeka ukuba umphezulu ovavanyiweyo une-scratchect okanye uthuli. Kungcono ukuvavanya iindawo ezintathu kunye netyhubhu efanayo. Ukuba amaxabiso emihlaba emithathu ngaphakathi ± 0.005, sebenzisa la maxabiso mathathu ukuthatha umndilili njengesiphumo sovavanyo. Oku kuyakuphepha iimpazamo ezibangelwa kukukrala kwaye kuthintela ukuthatha elona xabiso liphezulu lempazamo yeTube. Ukuba ityhubhu efanayo ithathwe ngaphezulu kwamaxesha ama-6 kwaye ayinakufumana amaxabiso amathathu ngaphakathi kwi- ± 0.005, ke kukho ingxaki ngale tyhubhu (i-tifomull ayilunganga).
