Abahlinzeki ababili banikeza i-potassium permanganate ekuhlanzekeni okungu-99.4%, kodwa amanani abo ayahluka. Iyiphi i-quotation enikeza inani elingcono?
Ukuhlanzeka kuyingxenye eyodwa kuphela yokuthenga. Ibanga lomkhiqizo, imikhawulo yokungcola, ukupakishwa, inani, imigomo yokulethwa nezimo zokukhokha konke kungathinta intengo.
Kubathengi abathenga isitoko ukuze sidayiswe kabusha, umbuzo obalulekile uthi: Kuzobiza malini ukwamukela izinto ezihlangabezana nezidingo zamakhasimende akho?
Intengo ephansi ingase ibonise ukutholakala okusebenzayo. Intengo ephezulu ingase ihlanganise ukucaciswa okuhlukile noma amasevisi. Intengo iyodwa ayiqambi ikhwalithi.
'99.4% ubumsulwa obuncane' busho ubuncane bokuqukethwe kwe-KMnO₄. Ayichazi konke ukungcola, usayizi wezinhlayiyana noma isici sokuphatha.
Cela ukucaciswa okuphelele kanye Nesitifiketi Sakamuva Sokuhlaziya, noma i-COA. Njengereferensi, i-Aozun ishicilelwe Izimpawu ze-potassium permanganate zihlanganisa:
Ipharamitha |
Ukucaciswa |
|---|---|
KMnO₄ ubumsulwa |
≥99.40% |
Indaba engancibiliki emanzini |
≤0.12% |
Okuqukethwe kwe-Chloride |
≤0.01% |
Okuqukethwe kwe-sulfate |
≤0.05% |
Umswakama |
≤0.5% |
Lena imikhawulo ebekiwe. Iqoqo elifanele le-COA kufanele likhombe inkatho futhi linikeze imiphumela yokuhlolwa etholakalayo.
Qinisekisa futhi ibanga. Imikhiqizo yobuchwepheshe, egeleza mahhala kanye ne-reagent yaselabhorethri ingaba nezidingo ezahlukene. Iphesenti lokuhlanzeka lilodwa aliqinisekisi ukuthobelana nebanga elithile noma isitifiketi.
Qhathanisa amapharamitha afanayo, amayunithi nezindlela zokuhlola ngaphambi kokuphatha okunikezwayo okubili njengokulinganayo.
Ukupakishwa kuthinta ukwamukela, ukugcinwa kanye nokulethwa okuqhubekayo. Qinisekisa isisindo senetha ngesigubhu ngasinye, uhlobo lwesiqukathi, ukuvala, amalebula nezinhlelo zephalethi—nokuthi afakiwe yini enanini.
Uma amakhasimende akho ethenga izigubhu ezigcwele, ukufanisa usayizi wephakethe lawo alithandayo kungenza ukwabiwa kwesitoko kube lula futhi kunciphise ukuphatha okwengeziwe.
Ukuze uthole ama-oda avamile, qinisekisa futhi:
Ukuvumelana komkhiqizi, izinga kanye nencazelo okuvunyelwene ngayo
Ukutholakala kwesitoko nesikhathi sokuhola sokukhiqiza
Ukuhlonza iqoqo kanye nama-COA ahambisanayo
Inqubo yokubika izindaba zekhwalithi
Lapho uhlola umphakeli omusha, vumelana ngemibandela yokwamukela futhi urekhode inombolo yesampula yeqoqo ngaphambi kokufaka i-oda lokuthengisa.
Hlola uhlobo lwemali, inani, imigomo yokulethwa, ichweba eliqanjwe igama noma indawo, izimo zokukhokha kanye nokufaneleka kwekhowutheshini.
Inani le-FOB kanye nenani le-CIF limboza izindleko ezihlukene. I-CIF ihlanganisa impahla yasolwandle kanye nomshwalense odingekayo endaweni ebizwa ngokuthi ichweba, kodwa akusho ukulethwa endaweni yakho yokugcina izinto.
Ukuqhathanisa okungokomfanekiso—hhayi amanani emakethe amanje
Cabanga ukuthi kokubili okunikezwayo kuhlangabezana nokucaciswa okufanayo, ukupakishwa kanye nenani le-oda.

Umhlinzeki A unenani lesihloko esiphansi. Ngemva kokwengeza impahla kanye nomshwalense, Umhlinzeki B ungu-USD 40/MT ngaphansi—umehluko we-USD 800 ku-oda lokucabanga elingu-20 MT.
Engeza izindleko zendawo oya kuzo ezikhokhelwa umthengi, imvume yokungenisa, imisebenzi, izintela ezisebenzayo kanye nezinto zokuhamba eziya ezweni ngokuhlukene ukuze ubale izindleko endaweni yakho yokugcina impahla. Gwema ukubala noma yiziphi izindleko kabili.
Ukuze uthole ukucatshangelwa kokuthunyelwa namadokhumenti, bheka yethu Umhlahlandlela we-potassium permanganate wokungenisa nokuthekelisa.
Cha. Umehluko ungase uvele ekucacisweni, ukupakishwa, inani le-oda noma imigomo yokulethwa. Cela umphakeli ukuthi akuchazele ukuthi ikhotheshini ihlanganisani.
Zingase zehluke ngokungcola, usayizi wezinhlayiyana, ukugeleza nokuziphatha kokuhlakazeka. Okuqukethwe kwe-KMnO₄ okuqinisekisiwe okulinganayo kunikeza inani elifanayo lethiyori lekhemikhali esebenzayo; izinzuzo zokusebenza kufanele zisekelwe ukuhlolwa okufanele.
Cela imininingwane egcwele, i-COA yakamuva, i-SDS, imininingwane yokupakisha kanye nemibandela yezohwebo ebhaliwe. Qinisekisa amadokhumenti enqwaba yokuthunyelwa afanele ngaphambi kokuthunyelwa.
Ukuze uthole isilinganiso se-potassium permanganate, sicela unikeze:
Isicelo esihlosiwe kanye nemininingwane edingekayo
Inani kanye nemvamisa yokuthenga elindelekile
Izidingo zokupakisha nephalethi
Indawo okuyiwa kuyo, imigomo yokulethwa ekhethwayo kanye nedethi yokuthunyelwa
Noma yiziphi izidingo zemibhalo eziqondene nekhasimende
Uma uqhathanisa okunye okunikezwayo, faka ukucaciswa kwakho kanye nesisekelo sokulethwa ukuze sikwazi ukucaphuna ngemibandela efanayo.
