16mm zomveka bwino kwambiri glod code
Mafuta a oxygen amafunikira machubu oyesera ndi zida zofunikira pakuwunika kwamadzi, kugwiritsidwa ntchito kwambiri m'matumbo, mafakitale, komanso kuyesedwa kwachilengedwe. Machubu apaderawa adapangidwa kuti azitha kupirira kutentha kwambiri komanso mikhalidwe yovuta ya mankhwala mkati mwa chimbudzi cha mankhwala. Tiyeni tidzilowe m'magulu ofunikira komanso machitidwe abwino ogwiritsa ntchito machubu a cod.

1️⃣ zakuthupi ndi zomangamanga
Chuma cha COD nthawi zambiri chimapangidwa ndi galasi la borosiltite galasi, lomwe limadziwika chifukwa cha kutetezedwa kwake komanso kugwiritsa ntchito mankhwala.
Machubu amasindikizidwa ndi chitseko champhamvu, nthawi zambiri chimakhala ndi PTF.
Njira yachiwiri ya 2️⃣
Ma chubu cha cod amagwiritsidwa ntchito molumikizana ndi chinsinsi cha cod, chomwe chimatentha zitsanzo kuti 150 ° C kwa maola awiri.
Panthawi imeneyi, zinthu zachilengedwe mu sample zimaxidid ndi wothandizira wambiri wa oxidizing (nthawi zambiri potaziyamu diokbomate) pamaso pa sulfuric acid.
Kuchuluka kwa mpweya wofunikira kwa oxidation iyi ndi muyeso wa cod, womwe umatha kuyerekeza umunthu.
3 ️⃣ mitsinje ndi mapulogalamu
Ma tubeni a cod akupezeka m'mitundu yosiyanasiyana kuti ikhale ndi mitundu yosiyanasiyana ya zitsanzo ndipo amayembekeza ma cod.
Mitundu yofala imaphatikizira yotsika (3-150 mg \ / l), sing'anga (20-1500 mg \ / l), ndi kukwera (200-15000 mg \ / l).
Machubu awa amagwiritsidwa ntchito poyesa kuyesa zinyalala zamadzimadzi komanso mafakitale, komanso zitsanzo zamadzi zamadzi.
4 Zochita Zabwino
Nthawi zonse tsatirani malangizo a wopanga zokonzekera zitsanzo, kugaya, ndi kusanthula.
Onetsetsani kuti machubu a cod ndi omasuka ku kuipitsidwa ndipo kuti sampuliyo imasakanizika bwino kusanthula.
Gwiritsani ntchito madzi okwera chifukwa cha kutsimikizira ndikukonzekera kukonzanso kuti muchepetse kusokonekera.
Maganizo a chitetezo
Ma tekisi a cod ali ndi zoopsa, monga mercury ndi chromium, zomwe zimafuna kusamalira bwino.
Valani zida zoyenera zoteteza (PPE) pogwira ntchito ndi machubu a cod, ndikuchita kusanthula mu malo otetezedwa.
Mwa kumvetsetsa mawonekedwe ofunikira komanso machitidwe abwino ogwiritsa ntchito machubu a cod, mutha kuwonetsetsa kuti madzi abwino a COD, omwe amathandizira kuteteza chilengedwe ndi thanzi la anthu.
