Polyaluminium Chloride (Pac) 25% -30% Pochiza Madzi
Polyaluminium Chloride (PAC) ndi chinthu chopangidwa mwaluso komanso chothandiza kwambiri chomwe chimapangidwira kuyeretsa madzi. Imadziwika kuti Polyaluminium, PAC ndi polima yosungunuka m'madzi yomwe imagwira ntchito ngati coagulant. Ndi mawonekedwe ake apadera a AlCl3 ndi Al(OH) 3, zinthuzo ndizosasokoneza komanso zimatsekereza ma colloids ndi tinthu tating'ono m'madzi. Imapambana pakuchotsa zinthu zazing'ono za poizoni ndi ayoni azitsulo zolemera, zomwe zimapangitsa kuti zikhale zoyenera kuyeretsa madzi.

Potaziyamu Carbonate99% Kwa Makampani Opanga Zinthu
Potaziyamu carbonate ili ndi mankhwala a K2CO3 ndi molekyulu yolemera 138.206. Ndi chinthu chachilengedwe chomwe chimagwiritsidwa ntchito ndikugwiritsa ntchito mosiyanasiyana. Ufa woyera wa crystalline uwu uli ndi mphamvu ya 2.428g / cm3 ndi malo osungunuka a 891 ° C, zomwe zimapangitsa kuti zikhale zowonjezera zapadera kwa mafakitale osiyanasiyana. Lili ndi zinthu zina zochititsa chidwi monga kusungunuka m'madzi, kusungunuka kwake kwamadzi, komanso kusasungunuka mu ethanol, acetone, ndi ether. Kuphatikiza apo, hygroscopicity yake yolimba imalola kuti itenge mpweya woipa wa carbon dioxide ndi chinyezi mumlengalenga, ndikusandulika kukhala potassium bicarbonate. Kuti musunge kukhulupirika kwake, ndikofunikira kusunga ndikuyika potaziyamu carbonate mopanda mpweya.

Sodium Cyanide 98% ya mankhwala ophera tizilombo
Sodium cyanide, yomwe imadziwikanso kuti kaempferol kapena kaempferol sodium, ndi gulu lamphamvu lomwe limagwiritsidwa ntchito mosiyanasiyana. Dzina lake lachi China ndi sodium cyanide, kusonyeza kutchuka kwake m'mafakitale osiyanasiyana padziko lonse lapansi. Pulogalamuyi, yokhala ndi mankhwala a NaCN ndi kulemera kwa molekyulu ya 49.007, yakopa chidwi kwambiri chifukwa cha zinthu zake zapadera komanso zosinthika.
Nambala yolembetsa ya CAS ya sodium cyanide ndi 143-33-9, ndipo nambala yolembetsa ya EINECS ndi 205-599-4. Ndi ufa wa crystalline woyera wokhala ndi malo osungunuka a 563.7 ° C ndi malo otentha a 1496 ° C. Kusungunuka kwake m'madzi ndi kachulukidwe kosungunuka ka 1.595 g/cm3 kumapangitsa kuti ikhale yosavuta kugwiritsa ntchito pazinthu zosiyanasiyana. Momwe maonekedwe amawonekera, sodium cyanide imadziwika bwino mu mawonekedwe ake oyera a crystalline ufa, zomwe zimawonjezera kukongola kwa mafakitale aliwonse.
Moni, bwerani mudzakambirane zinthu zathu!
