Kub kub thiab siab purity silica amorphous nruam fiber ntau daim ntaub
Refractory fiber yog ib hom kub resistant inorganic fiber, cov ntsiab lus ntawm silicon dioxide (SiO2) yog siab tshaj 96%, lub softening point yog ze rau 1700 ℃, ntev siv nyob rau hauv 900 ℃, 1450 ℃ nyob rau hauv cov kev mob ntawm kev ua hauj lwm. rau 10 feeb, 1600 ℃ nyob rau hauv cov xwm txheej ntawm lub rooj 15 vib nas this tseem nyob rau hauv zoo.High silicon oxygen refractory fiber ntau daim ntaub muaj cov yam ntxwv ntawm lub zog siab, ua haujlwm yooj yim, siv dav, siv los ua qhov kub thiab txias, ablative tsis kam, rwb thaiv tsev kub, cov khoom txuag hluav taws xob.
High silicon oxygen daim ntaub yog ib yam ntawm tshav kub resistant, mos tshwj xeeb siv lead ua fiber ntaub, nws cov ntsiab lus SiO2 ncav cuag ntau tshaj 96%.Cov khoom lag luam muaj cov yam ntxwv ua kom sov zoo, tuaj yeem siv rau hauv 1000 ℃ ib puag ncig rau lub sijhawm ntev, kev kub ceev tiv thaiv kub txog 1400 ℃, siv Na2O-B2O3-SiO2 ternary system iav raw cov ntaub ntawv, qhov muag kub ntawm cov kua qaub yog 1700 ℃.
Cov ntawv thov: muaj kev kub siab kub rwb thaiv tsev, rwb thaiv tsev, sealing, xub, missiles, spacecraft thermal ablative cov ntaub ntawv, hluav taws kub tiv thaiv suit hluav taws kub cov hnab looj tes tshwj xeeb kub, thiab lwm yam.
Cov yam ntxwv ntawm cov khoom: tsis tshua muaj thermal conductivity, zoo tshuaj stability, tsis tshua muaj thermal shrinkage, non-asbestos cov khoom, tsis muaj kuab paug, ua hauj lwm zoo, kub tsis kam, rwb thaiv tsev kub, thermal preservation, sealing khoom.
