Product Detail

Khoom cim npe

Qhov zoo ntawm roj av coke feem ntau nyob ntawm qhov xwm ntawm cov khoom siv raw thiab nws cov kev ua haujlwm.Lub ntsiab zoo ntsuas yog:

Purity
Hais txog cov ntsiab lus ntawm sulfur thiab tshauv hauv roj av coke.High-sulfur coke yuav ua rau cov khoom o thaum lub sij hawm graphitization, ua rau cov kab nrib pleb hauv cov khoom carbon.Cov hmoov tshauv siab yuav cuam tshuam cov crystallization ntawm cov qauv thiab cuam tshuam rau kev ua haujlwm ntawm cov khoom siv carbon.

Crystallinity
Hais txog cov qauv ntawm cov coke thiab qhov loj ntawm mesophase spheres.Cov coke tsim los ntawm cov spheres me me muaj cov qauv ntxeem tau xws li daim txhuam cev zoo li, thiab cov coke tsim los ntawm cov spheres loj muaj cov qauv ntom ntom xws li fibrous lossis rab koob zoo li, thiab nws qhov zoo tshaj plaws ntawm daim txhuam cev coke.Nyob rau hauv qhov Performance index, qhov ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom zoo.

Thermal shock resistance
Hais txog qhov tawg tsis kam ntawm cov khoom coke thaum lawv raug thermal shocks dheev nce mus rau qhov kub thiab txias los ntawm qhov kub thiab txias.Cov khoom ntawm koob coke muaj qhov zoo thermal poob siab tsis kam, yog li lawv muaj txiaj ntsig zoo siv.Lub coefficient ntawm thermal expansion sawv cev rau cov cuab yeej no.Qhov qis dua qhov coefficient ntawm thermal expansion, qhov zoo dua thermal shock kuj.

Graininess
Cov ntsiab lus txheeb ze ntawm hmoov coke thiab loj heev granular coke (usable coke) muaj nyob rau hauv cov tshuaj tiv thaiv coke.Feem ntau ntawm cov hmoov coke yog tawg los ntawm kev siv tshuab xws li kev sib txhuam extrusion nyob rau hauv cov txheej txheem ntawm decoking, cia thiab tsheb thauj mus los, yog li nws cov nyiaj kuj yog ib qho kev tshwm sim ntawm txhua yam muaj zog.Cov coke ntsuab tuaj yeem tiv thaiv kom tsis txhob tawg tom qab calcined rau cov laus coke.Lub coke nrog ntau granular coke thiab tsawg hmoov coke muaj ntau dua tus nqi siv.
