Khoom Paub meej
Cov khoom no yog ua los ntawm zoo-grained siab- purity graphite substrate, uas tau raug kho los ntawm siab - kub densification. Nws yog ua ke nrog ib qho tshwj xeeb cam khwb cia txhuas- qib anti- oxidation txheej. Cov khoom siv tsis hnov mob chemically nrog molten aluminium, tsis lo rau txhuas, thiab tsis nqus txhuas. Nws yog tsim los ntawm precision machining, haum rau cov txheej txheem xws li txhuas kua degassing, ntws diversion, shaping, thiab txias thiab shaping. Tag nrho cov txheej txheem nruj me ntsis tswj cov hmoov tshauv qis cov ntsiab lus los tiv thaiv impurity paug ntawm cov kua txhuas thiab ua tau raws li cov qauv nruj rau kev tsim khoom loj ntawm automotive precision aluminium castings.
Khoom nta
1. Resistant erosion los ntawm molten aluminium thiab tsis flake lossis hmoov tawm txawm tias tom qab ntev - immersion.
2. Tsis tshua muaj thermal expansion coefficient, tsis deform thaum lub sij hawm siab - kub casting, thiab tuav ruaj khov casting qhov ntev.
3. Tus kheej-lubricating thiab tsis yog- nplaum txhuas nto, du demolding, txo qhov tsis xws luag ntawm cov castings.
4. Uniform thiab ceev cov cua kub conduction, accelerating lub solidification ntawm txhuas cov kua thiab txhim kho cov kev sib raug zoo ntawm txhuas casting.
5. Kev tiv thaiv oxidation zoo heev, nrog lub neej ua haujlwm ntev dua nyob rau hauv siab - qhov cub kub dua li cov khoom siv graphite.
Khoom zoo
Ordinary graphite cov khoom muaj cov hmoov tshauv siab, nws nquag ua raws li txhuas, thiab muaj kev cuam tshuam rau oxidation. Qhov no tuaj yeem ua tau yooj yim ua rau huab cua ntau dhau nyob rau hauv tsheb aluminium castings, qhov chaw ntxhib, thiab cov nqi qis. Cov series ntawm cam khwb cia txhuas- tshwj xeeb graphite qhov chaw hauv cov khoom no tau dhau los ua ob txheej txheem ntawm kev sib khi qhov thiab tiv thaiv - kev kho oxidation. Lawv tsis paug cov kua txhuas thiab muaj cov teebmeem degassing ruaj khov. Qhov no tuaj yeem txo qhov seem ntawm cov cam khwb cia txhuas, txo qhov zaus ntawm cov cuab yeej kaw thiab hloov pauv, txo cov nqi tsim khoom ntawm cov tsheb tuag-casting ntau lawm kab, thiab tsim nyog rau loj - nplai automated cam khwb cia txhuas cov kab ntau lawm.

Teeb meem
-
Graphite qhov chaw lo rau aluminium
Ordinary graphite muaj qhov pores loj. Lub tshuab kaw qhov ua haujlwm tau txais kev pom zoo los tiv thaiv cov kua txhuas los ntawm kev nkag mus thiab adhering.
-
Ntau qhov pores hauv castings: High-purity thiab qis- cov khoom siv sulfur, ua ke nrog cov degassing graphite rotor, ua kom huv huv cov kua txhuas.
-
Lub neej ua haujlwm luv
Exclusive cam khwb cia txhuas los tiv thaiv- oxidation txheej, ncua siab - kub oxidation poob, thiab ncua lub sij hawm kev pab cuam.
