Ua haujlwm ib puag ncig: Nqus / inert cua (Ar / N₂), siab nqus ntawm 10⁻³ ~ 10⁻⁶ Pa, ultra- kub ntawm 1800–2600℃.
Cov haujlwm tseem ceeb: Tsau graphite cua sov phaj nyob rau hauv lub cub tawg, graphite xav tias rwb thaiv tsev txheej, cov khoom tais, electrodes, cuab yeej fixtures; los yog siv los ua cov ntsia hlau kis tau tus mob (trapezoidal xov), rau kub nias, nqa, thiab hloov pauv hloov; Hloov cov ntsia hlau hlau los daws cov teeb meem xws li hlau siab -kub creep, txias welding sticking, gas emission pollution, thiab oxidation tsis ua hauj lwm.
Cov kev qhia tshwj xeeb: M3–M24, tsis yog - tus qauv kab / ntev; threads yog triangular hniav (fastening) thiab trapezoidal hniav (kev sib kis); nruab nrog graphite ceev thiab graphite gaskets.
Lub tshuab nqus tsev siab uas tsis tshua muaj roj to, siab purity ib puag ncig nrog xoom kuab paug (tseem ceeb rau semiconductors / photovoltaics)
Cov ntsiab lus ruaj khov ntawm cov khoom siv raw yog ntau dua lossis sib npaug rau 99.95%, nrog cov ntsiab lus tsis zoo tsis zoo. Lub tshuab nqus tsev vacuum tsawg dua los yog sib npaug rau 10−8 Pa⋅m3/(m2⋅s), uas tuaj yeem ua tau raws li cov txheej txheem nqus tsev siab ntawm 10−6 Pa.
Nyob rau hauv qhov chaw siab - kub thiab lub tshuab nqus tsev, cov ntsia hlau hlau yuav tso tawm cov pa hlau, cov roj seem thiab cov roj tsis huv, uas yuav ua rau cov khoom siv silicon wafers, wafers, hard alloys, thiab precision workpieces, ncaj qha ua rau cov khoom tawg.
Graphite tsis muaj hlau los nag lossis dej tsis haum. Tag nrho cov txheej txheem tswj xyuas qhov huv ntawm lub cub tawg, ua kom lub purity thiab zoo li zoo ntawm high - khoom kawg los ntawm qhov chaw.
3. Raws li nws tus kheej-lubricating, nws yeej tsis tau daig hauv lub tshuab nqus tsev thiab yuav tsum tsis muaj roj lubricating.
Nyob rau hauv siab - qhov kub ntawm lub tshuab nqus tsev kub, lubricating roj thiab roj (uas yuav carbonize, tso pa roj, thiab paug lub cub tawg chamber) raug txwv. Qhov no yog qhov mob loj tshaj plaws rau cov hlau fasteners:
Thaum cov xov hlau tsis yog lubricated, lawv yooj yim rau vuam txias thiab xauv ua ke ntawm qhov kub thiab txias, ua rau nws tsis tuaj yeem disassemble tom qab. Nws tsuas tuaj yeem raug yuam kom disassembled, ua rau muaj kev puas tsuaj rau cov khoom hauv lub qhov cub.
Graphite muaj cov txheej txheem ntuj tsim nws tus kheej -lubricating khoom. Siv graphite screws nrog graphite ceev, cov txheej txheem kev sib hloov thiab disassembly yog du thoob plaws. Nws yuav tsis tau daig txawm tias tom qab siv sijhawm ntev -, txo qhov nyuaj ntawm cov khoom siv tu thiab sijhawm poob.
Core Advantage
Kev ua tau zoo ntawm cov khoom siv
Siv high-purity graphite ua cov khoom siv hauv paus thiab sib txuas nrog qis-kub sintering tshuab, cov ntsia hlau tuaj yeem tswj cov qauv kev ruaj ntseg ntawm qhov kub ntawm 2500 degree, tshem tawm qhov kev pheej hmoo ntawm thermal stress cracking.
Zoo heev thermal conductivity
Qhov saum npoo yog kho nrog nano- txheej, ua kom cov thermal conductivity thiab txo qhov kev pheej hmoo ntawm cov cua sov hauv zos, ua kom qhov sib xws ntawm qhov kub thiab txias hauv lub tshuab nqus tsev vacuum thiab txhim kho cov txheej txheem kev ruaj ntseg.
Customization thiab adaptation
Jin Cheng Graphite muab tag nrho - cov txheej txheem kev pab cuam los ntawm kev tsim mus rau ntau lawm, txhawb kev hloov kho ntawm cov ntsia hlau qhov ntau thiab tsawg, xov specifications, thiab sealing slots raws li cov neeg siv khoom xav tau, thiab hloov mus rau cov khoom siv lub tshuab nqus tsev loj thoob ntiaj teb.
Qhov tseem ceeb tshaj plaws kom zoo dua
Kev tiv thaiv tsis zoo rau qhov kub thiab txias, tiv taus thermal shock thiab tsis muaj siab -kub creep (qhov tseem ceeb kom zoo dua).
Hauv cov huab cua tsis zoo xws li lub tshuab nqus tsev, nitrogen, thiab argon, nws tuaj yeem ua haujlwm tsis tu ncua ntawm 2200℃rau lub sijhawm ntev, thiab tiv taus luv luv -lub sijhawm ultra- siab kub txog li 2600℃.
Qhov siab tshaj plaws kev khiav hauj lwm kub ntawm zoo tib yam stainless hlau screws tsuas yog 600 mus rau 800 degree. Txawm tias qhov kub ntawm - kub alloys, lawv tsis tuaj yeem tshaj 1400℃rau lub sijhawm ntev. Thaum overheated, lawv yuav maj mam soften, ncab, thiab nkag mus deformation, uas ua rau xoob threads thiab puas.
Graphite, ntawm qhov tod tes, tswj nws cov neeg kho tshuab lub zog txawm tias qhov kub thiab txias thiab muaj qhov thermal expansion coefficient (degree). Nws tuaj yeem tiv taus qhov thermal shock tshwm sim los ntawm kev hloov pauv kub ntawm lub tshuab hluav taws xob ntau zaus, suav nrog cua kub ceev thiab txias, tsis ua rau cov xov hloov pauv, tawg, lossis deformation. Nws yog haum rau 24-teev nruam ntau lawm tej yam kev mob.
