Daim ntawv thov ntawm Boron-Nitride nyob rau hauv High Temperature Release Agent

Siv rau kev ua haujlwm ntawm kev sib sib zog nqus-bending, tshwj xeeb-puab, kub-muab, ntshiab-ci thiab lwm yam iav nkhaus, cov nyhuv zoo kawg li. Nws kuj yog tsim rau demoulding, tso tawm thiab lubrication ntawm ntau yam hlau ua xws li hlau forging, tuag-casting, txhuas extruded iav khoom, thiab lwm yam. Nws kuj yuav siv tau nyob rau hauv welding thiab furnace brazing txheej txheem, uas yuav tiv thaiv lub nto ntawm lub workpiece. los ntawm kev puas tsuaj los ntawm splashing ntawm vuam slag. Ua lub luag haujlwm tiv thaiv hauv cov txheej txheem vuam hlau.

yam ntxwv

1. Lubricity zoo: Tom qab tshwj xeeb thiab zoo hmoov sib xyaw, nws tuaj yeem ua tau zoo thiab zoo txuas rau saum npoo ntawm cov pwm, tsim cov nyhuv lubricating zoo. Vim hais tias hexagonal boron nitride yog kiag li du, coefficient ntawm kev sib txhuam ntawm cov hmoov yog tsawg heev, thiab txhua txheej ntawm nws atomic qauv muaj boron thiab nitrogen, thiab tsis muaj BN bonding ntawm cov khaubncaws sab nraud povtseg, yog li cov dav hlau swb ntawm ib leeg, ua rau softness. thiab Lubricant nyhuv, haum heev rau kev kub siab tso tawm tus neeg sawv cev daim ntawv thov.

2. Ntev lub neej ntawm pwm: zoo txo ​​qhov poob ntawm pwm thiab txo lub sij hawm xav tau rau kev tu cov pwm. Thaum lub sij hawm ua cov txheej txheem iav, nws tuaj yeem txo qhov tsis xws luag ntawm cov khoom iav thiab ua rau cov iav yooj yim rau demould.

3. Kev ua haujlwm zoo: cov tshuaj tsuag tshwj xeeb, uas tuaj yeem sib npaug ntawm cov pwm ntawm tes.

4. Qhov kub thiab txias tsis kam: zoo heev thermal shock resistance, txawm tias qhov kub thiab txias yog 1500 degree ceev cua sov thiab txias dua ob peb zaug, nws yuav tsis tawg, txawm tias nws yog rhuab mus rau 2200 degree, nws tseem tuaj yeem siv nrog kev thaj yeeb nyab xeeb.

5. Ceev ceev kom qhuav: tshwj xeeb ceev-qhuav mis, ceev kom qhuav ceev, kev txhim kho ntau lawm efficiency thiab txo nqi.

6. Tsawg coefficient ntawm kev sib txhuam: kev sib txhuam coefficient u tsuas yog 0.16, tsis nce ntawm qhov kub thiab txias, tiv taus kub ntau dua li molybdenum disulfide thiab graphite, thiab tuaj yeem siv mus txog 800 degree hauv oxidizing. huab cua, thiab mus txog 2000 degree nyob rau hauv lub tshuab nqus tsev.

7. Zoo corrosion kuj: sib xws nrog cov hlau dav hlau (hlau, tooj liab, txhuas, txhuas, thiab lwm yam), cov hlau tsis tshua muaj hauv ntiaj teb, cov hlau tseem ceeb, cov khoom siv semiconductor (germanium, silicon, potassium arsenide), iav, molten ntsev (crystal pob zeb, fluoride. , slag), inorganic acids thiab alkalis tsis hnov ​​mob

8. Machinability: Nws Mohs hardness yog 2, yog li nws tuaj yeem ua tiav rau hauv cov khoom siv siab thiab cov khoom siv los ntawm cov txheej txheem machining.

Daim ntawv thov:

Nrog rau kev loj hlob sai ntawm cawv, khoom noj, dej haus thiab lwm yam kev lag luam, qhov kev thov rau ntau yam ntim iav fwj thiab jars tau nce. Lub tshuab txiav txim siab lub raj mis ua tshuab tau dhau los ua tus qauv tseem ceeb ntawm cov iav lub raj mis ntau lawm thiab tau siv dav, thiab kev khiav ceev ntawm lub tshuab txiav txim siab lub raj mis ua tshuab tau nrawm dua thiab nrawm dua, thiab cov kev xav tau rau cov iav pwm lubrication thiab tso tawm tus neeg sawv cev tau nce siab dua thiab siab dua. Cov txheej txheem ib txwm siv ntawm lubricating thiab demolding iav pwm siv phau ntawv los yog siv tshuab txau ntawm cov tsiaj thiab zaub roj, thiab cov nyhuv dav tsis zoo.

Cov khoom siv boron nitride lubricating yog siv los txhim kho lub lubricating thiab demoulding nyhuv. Tam sim no, dav siv boron nitride tso cov neeg ua haujlwm feem ntau muab faib ua peb pawg hauv qab no:

Thawj hom siv dej los ua qhov nruab nrab thiab ntxiv cov nplaum nplaum thiab lwm yam khoom ntxiv los ua cov dej-raws li lubricants, uas yog txhuam rau saum npoo ntawm pwm ib zaug thiab siv tom qab ziab los ua ib zaj duab xis.

Lwm hom siv roj raws li qhov nruab nrab thiab ntxiv cov khoom siv ntxiv los ua cov roj nplua nyeem, uas txuas ntxiv txhuam los yog txau thaum lub sijhawm ua haujlwm ntawm lub tshuab txiav txim siab lub raj mis.

Feem ntau siv boron nitride tso tawm tus neeg sawv cev yog los coated high-viscosity ntxhia roj nrog boron nitride, thiab sib tov dej nyob rau hauv qhov kev txiav txim ntawm ib tug emulsifier los ua ib tug emulsified roj-hom iav pwm lubricating tso tus neeg saib xyuas. Boron nitride: roj: dej=1: 4:10, thaum tus nqi ntawm emulsifier yog 7wt feem pua, cov npaj emulsified roj tso tus neeg sawv cev muaj kev ruaj ntseg zoo, zoo tso tawm kev ua tau zoo, thiab muaj cov yam ntxwv ntawm nyias roj zaj duab xis thiab uniform tis. . Kev siv cov boron nitride lubricating thiab tso tawm tus neeg saib xyuas txhim kho cov txiaj ntsig ntawm lub raj mis ua, txo kev noj cov roj lubricating thiab tso tawm tus neeg sawv cev, thiab ntxuav qhov chaw tsim khoom.

Daim ntawv thov ntawm Boron Nitride Release Agent hauv Hlau Casting, Melting thiab Vuam

tus

Hexagonal boron nitride muaj tshuaj lom neeg ruaj khov thiab tuaj yeem tiv taus cov hluav taws xob hluav taws xob ntawm cov hluav taws xob nuclear. Nws tsis cuam tshuam los ntawm acid thiab alkali. Nyob rau hauv ib qho chaw inert (nitrogen los yog argon), qhov decomposition kub yog siab li 2500 degree C. Nws qhia tau hais tias kev ua tau zoo heev nyob rau hauv huab mob. Zoo heev tshuaj stability.

tus

Hexagonal boron nitride tuaj yeem ua rau boron nitride sib cais rings (Daim duab 3) rau kab rov tav nruam casting ntawm hlau. Hexagonal boron nitride yog ruaj khov heev rau carbon thiab carbon monoxide ntawm 1800 degree C, thiab tsis corroded los ntawm molten iav, silicon, boron, non-oxide slag, molten ntsev (borax, cryolite) nyob rau hauv hlau.

tus

Hexagonal boron nitride tuaj yeem ua rau hauv lub plhaub sib xyaw rau titanium hlau casting. Cov tshuaj stability ntawm titanium hlau tsis zoo. Thaum lub forging yog deformed quab yuam ntawm qhov kub thiab txias, qhov chaw tshiab uas tsim los ntawm cov hlau ntws yog yooj yim heev los lo rau cov tuag, ua rau lub forging thiab tuag yuav tsum scrapped tib lub sij hawm. Lub plhaub txheej txheej ntawm boron nitride tso tawm tus neeg sawv cev yog coated rau saum npoo ntawm pwm kom tsis txhob muaj kev sib cuag ncaj qha ntawm titanium hlau thiab pwm.

tus

Hexagonal boronnitride kuj tseem tuaj yeem siv rau hauv vuam thiab cub tawg txheej txheem, uas tuaj yeem tiv thaiv qhov chaw ua haujlwm los ntawm kev puas tsuaj los ntawm kev sib tsoo ntawm vuam slag, thiab tuaj yeem ua lub luag haujlwm tiv thaiv hauv cov txheej txheem hlau vuam.

Shengyang New Material Co., Ltd. tau cog lus rau kev tsim cov boron nitride thiab boron nitride ua cov khoom lag luam, thiab tuaj yeem kho ntau yam boron nitride insulating ceramic qhov chaw raws li cov neeg siv khoom xav tau. Tiv tauj peb yog tias tsim nyog.
