Silica powder BET surface area: Yog li cas li nws tseem ceeb rau cov kev siv hauv tswj hwm tswv yim

Thaum xaiv cov pov tseg silica rau kev siv hauv tsev tsim khoom, tsuas muaj ib qho tshuaj cim uas yog qhov tseem ceeb tshaj plaws, ntawd yog BET surface area. BET surface area yog qhov muaj ntau npaum li cas ntawm qhov qhia qhov ntev ntawm cov pov tseg silica per unit mass, thiab nws muaj kev nyuaj siab rau kev siv pov tseg silica hauv cov khoom rubber, cov khoom kho, cov khoom ceramic, thiab lwm yam khoom ntxiv uas muaj kev nyuaj siab rau kev nyuaj. Hebei Runhuabang New Material Technology Co., Ltd yog ib qho tsev tsim khoom uas siv pov tseg, kho, thiab xa cov khoob tshuaj tsis muaj loj (non-metallic mineral) zoo li cov pov tseg silica rau kev siv hauv tsev tsim khoom zoo.

Paub txog BET Surface Area thiab nws qhov tseem ceeb

BET qhov looj pliag ntawm cov ntaub ntawv yog li no vim tias cov neeg siv cov lus qhia uas qhia txog kev xam qhov looj pliag ntawm cov ntaub ntawv los ntawm kev daws tawm cov hauv qab ntsuas, Brunauer, Emmett thiab Teller. Rau lub tswv yim tshwj xeeb, yuav tshaj plaws qhov looj pliag BET, yuav tshaj plaws qhov ntau ntawm qhov looj pliag uas tuaj yeem siv rau hauv kev sib koom tes ntawm cov ntaub ntawv silica thiab cov ntaub ntawv nyob ib puag ncig. Rau hauv qhov kev lag luam, qhov no muaj kev cuam tshuam rau kev pab nce qhov siab ntawm kev pab, kev paub tswj qhov ntau ntawm cov ntaub ntawv thiab kev paub tswj kev khiav tawm. Kev ua haujlwm ntawm cov khoom tuaj yeem nce siab heev nrog cov ntaub ntawv silica uas muaj qhov looj pliag BET uas tau qhia kom zoo, tsis txhob cuam tshuam rau kev siv haujlwm. Qhov siv cov kev lag luam tshiab, thiab kev tswj cov ntaub ntawv hauv txhua qhov, tau pab Hebei Runhuabang New Material Technology Co., Ltd. ua cov ntaub ntawv silica uas muaj qhov looj pliag BET zoo ib yam thiab tshwj xeeb raws li cov neeg siv tau xav.

Kev cuam tshuam rau rubber Kev pab thiab kev ua haujlwm ntawm cov rooj

Thaum peb txhawj xyuam txog kev tsim rubber, qhov tshwj xeeb tseem ceeb tshaj plaws rau kev txheeb xyuam qhov kev pab tau yog qhov BET surface area. Qhov silica powder uas muaj qhov ntsiab ntau dua yuav muaj ntau dua cov kev sib koom ntawm cov khoom siv thiab cov rubber polymer. Qhov kev sib koom ntau dua no yuav pab ua kom qhov tensile strength, tear resistance thiab abrasion resistance zoo dua. Tiamsis, qhov ntsiab loo li ntau kuj yuav pab ua rau kev sib sib npaj yooj dua thiab ua rau qhov compound viscosity ncaj ncees. Yog li ntawd, kev xaiv qhov BET surface area uas xwm yeem yuav tsum nyob rau hauv qhov sib twg ntawm qhov kev pab tau thiab qhov kev sib npaj. Rau hauv cov tire tread compounds, uas yuav siv los ua kom qhov rolling resistance hloov ntev thiab ua kom qhov wet grip zoo dua, cov silica powder uas muaj qhov BET surface area nyob rau hauv qhov sib twg ntawm moderate thiab high yog siv dav. Hebei Runhuabang New Material Technology Co., Ltd. pab cov neeg tsim rubber xaiv cov silica powder grades uas muaj qhov ntsiab zoo tshaj plaws rau lawv cov kev siv tshwj xeeb los pab tshem cov kev ua haujlwm thiab kev ua haujlwm.

Rog nyob rau hauv cov lus qhia thiab Tshuaj tshuaj Cov lus qhia

Cov kws tsim cov lus qhia thiab tshuaj tshuaj siv cov pov tseg silica rau cov qhov sib txawv li: ua kom muaj ntau dua, tswj cov pov tseg kom tsis tau nyob rau hauv qhov tsoo thiab ua kom muaj qhov rov qhia. Qhov cuam tshuam tsaum ntawd rau cov pov tseg silica nyob rau hauv cov qhov no yog BET cov ntsiab nplooj. Cov pov tseg silica uas muaj BET cov ntsiab nplooj siab yuav muaj qhov cuam tshuam thixotropic zoo dua, uas yog: cov lus qhia yuav yog liquid thaum siv, tab sis tom qab ntawd nws yuav ua kom muaj ntau dua kom tswj kom tsis tau nyob rau hauv qhov tsoo thiab tsis tau tshuaj. Rau cov lus qhia uas muaj qhov rov qhia, cov ntsiab nplooj ntawm cov pov tseg yuav cuam tshuam rau qhov light yuav tshuaj los ntawm cov ntsiab uas tau tshuaj. Cov pov tseg silica uas muaj BET cov ntsiab nplooj uas tau tswj tau zoo yuav muaj qhov cuam tshuam optical zoo tib yam rau txhua lub sijhawm. Hebei Runhuabang New Material Technology Co., Ltd. pab cov kws tshuaj tshuaj tau txais cov kev daws teb zoo tib yam los ntawm kev siv cov pov tseg silica uas muaj cov leej twg zoo thiab tsis muaj kev thim los ntawm kev thim lossis qhov rov qhia.

Qhov txaus siab rau Kev tshuaj thiab kev tshuaj tshuaj

Hauv cov kev lag luam uas xav tau qhov kev daws tawm lossis kev kho, qhov BET surface area yog sib txawv ntau dua. Cov pov tseg silica uas muaj qhov laj thawj siab yuav muaj ntau dua cov chaw ua haujlwm los daws tawm cov khoom tsis zoo, cov dej, thiab cov khoom tsis xav tau lwm yam. Qhov no yog qhov muaj txiaj ntsig rau qhov kho lub oil, kho lub qhov cua, thiab kev lag luam ntawv. Qhov sib sau rau lawv ob qhov yog qhov tshwj xeeb: yam uas laj thawj siab dua, yam uas daws tawm zoo dua.
