Dab tsi yog qhov cuam tshuam ntawm fumed silica ntawm nws qhov kev ua tau zoo hauv kev tsim cov silicone hose?
Tus nqi ntawm fumed silica nyob rau hauv silica gel raj yog loj heev, tshwj xeeb tshaj yog nyob rau hauv kub vulcanized silicone roj hmab, thiab nws ntxiv yuav ncav cuag 40 feem pua ~ 50 feem pua. Txawm hais tias precipitated silica tuaj yeem siv los ua cov khoom siv ntxiv ntawm silicone roj hmab, cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob ntawm cov roj hmab silicone uas muaj cov silica precipitated tsis zoo li cov uas muaj fumed silica vim nws cov dej nqus dej thiab cov ntsiab lus impurity; Yog li ntawd, fumed silica plays lub luag haujlwm tseem ceeb hauv daim ntawv thov no.
Fumed silica yog amorphous silica khoom npaj los ntawm hydrolysis ntawm halosilane ntawm qhov kub thiab txias los ntawm oxyhydrogen nplaim taws. Nws qhov loj me me yog nruab nrab ntawm 7 ~ 40nrn, nws qhov chaw tshwj xeeb yog feem ntau ntau dua 1002 / g, thiab cov ntsiab lus ntawm SO2 tsis tsawg dua 99.8 feem pua. Nws yog ib qho tseem ceeb heev inorganic nano hmoov khoom; Vim nws txoj kev ruaj ntseg zoo heev, kev txhawb zog, thickening thiab thixotropy, nws tau siv dav hauv kev lag luam roj hmab, plastics, electronics, coatings, adhesives thiab sealants.
Qhov thib ob, muaj peb yam tseem ceeb ntawm cov txheej txheem roj tshwj xeeb ntawm cov roj hmab ntuj.
1. Cov nyhuv tshwj xeeb fumed silica ntawm compression teeb thiab tsim kua muag lub zog ntawm ntuj roj hmab;
2. Cov nyhuv tshwj xeeb fumed silica ntawm flexural qaug zog ntawm ntuj roj hmab;
3. Cov nyhuv tshwj xeeb fumed silica rau brittleness kub thiab rebound tus nqi ntawm ntuj roj hmab;
Hauv ib lo lus, thaum tus nqi tshwj xeeb fumed silica r 300 hauv cov roj hmab ntuj yog 10 phr, lub zog tensile, elongation ntawm kev tawg thiab deformation ntawm cov roj hmab zoo dua. Raws li lub zog tsim kua muag thiab compression txheej txheem ntawm cov compound, qhov kev ua tau zoo ntawm cov fumed silica r 300 tshwj xeeb yog qhov zoo dua thaum qhov ntau npaum li 10 phr. Tom qab ntxiv 10 qhov chaw ntawm tshwj xeeb fumed silica r 300 rau hauv cov roj hmab ntuj, lub zog flexural qaug zog ntawm cov compound tau zoo tuaj.
Thaum ntxiv 10 qhov chaw tshwj xeeb fumed silica rau hauv cov roj hmab ntuj, tus nqi rov qab thiab brittleness kub ntawm cov roj hmab yog qhov zoo tshaj plaws. Tshwj xeeb fumed silica r 300 tsis tsuas yog muaj kev sib xyaw zoo thiab ua cov yam ntxwv, tab sis kuj tseem txhim kho kev ua haujlwm qaug zog ntawm cov roj hmab ntuj, ua kom muaj kev loj hlob zoo ntawm cov roj hmab, thiab txhim kho cov flexural qaug zog ntawm cov roj hmab ntau dua 50 feem pua.
