Lub cev lub cev:
Cov tsos ntawmnpib tsib xeeyog silvery dawb, nrog zoo luster, ntom ntawm 8.9 g / mm³, melting point ntawm txog 1455 degree, npau taw rau ntawm 2730 degree.
Nws yog qhov nyuaj, ferromagnetic thiab muaj cov zoo, nruab nrab tawv, thiab tuaj yeem yog polished heev.
Tshuaj lom neeg cov khoom:
Qhov tseem ceeb ntawm Nickel yog 2 thiab 3, thiab lub zog ionization yog 7.635 electron volts. Nws tsis yog oxidized nyob rau hauv huab cua, resistant rau muaj zog alkali thiab rog acid corrosion.
Nws tuaj yeem maj mam yaj nyob rau hauv dilute acid, tso hydrogen los ua ntsuab zoo ions positive positive రel ions ni²⁺; Nws tsis muaj kev cuam tshuam rau oxidant daws teeb meem suav nrog nitric acid.
Nickel phaj tuaj yeem tiv taus yaig los ntawm ntau yam kua qaub thiab alkaline daws, xws li sulfuric acid, hydrochloric acid, thiab lwm yam.
Nyob rau hauv cov huab cua kub thiab oxidizing huab cua, ib lub phaj dension olide olide tiv thaiv ob leeg, tiv thaiv cov oxygen los ntawm cov npib tsib xee thiab txhim kho cov khoom antioxidant.

Cov Lus Nug Txog Zhenan
Q: Koj puas tuaj yeem lav qhov kev xa khoom sai?
A: Yog, thaum peb tau txais koj cov lus nug, tsis yog peb yuav ntsuas tus nqi sib tw ntau dua, tab sis peb tuaj yeem tau txais lub sijhawm xa khoom zoo tshaj plaws. Yog li cov khoom xa tuaj sai tuaj yeem lav tau.
Q: Tus nqi thauj khoom yog dab tsi?
A: Tus nqi thauj khoom yog txiav txim siab los ntawm lub chaw nres nkoj, qhov hnyav, tag nrho CBM ntawm cov khoom xa tuaj, peb yuav sim ua kom cov neeg xa khoom lossis nthuav qhia cov neeg sawv cev.
Q: Qhov kev thauj mus los yog dab tsi?
A: Yog tias qhov hnyav tag nrho ntau dua lossis sib npaug ntawm 45kg, nws zoo dua los ntawm Express xws li TNT, DHL, FedEx ,, thiab lwm yam.
Yog tias qhov hnyav tag nrho ntawm 45kg mus rau 100kg, los ntawm kev nthuav qhia lossis los ntawm huab cua mus rau koj lub tshav dav hlau ze tshaj plaws tuaj yeem suav tau.
Yog tias qhov hnyav hnyav dua lossis sib luag rau 100kg, koj tuaj yeem xaiv los ntawm huab cua lossis dej hiav txwv mus rau qhov chaw nres nkoj ze tshaj plaws.
