Txoj kev loj hlob ntawm cov khoom siv rwb thaiv tsev
Jul 17, 2021
Kev tsim hluav taws xob rwb thaiv tsev yog qhov tseem ceeb ntawm kev txuag hluav taws xob, txhim kho kev nyob ib puag ncig thiab siv cov haujlwm. Kev siv lub zog siv hluav taws xob feem ntau suav txog 30-40% ntawm tib neeg kev siv hluav taws xob, thiab feem ntau yog siv hluav taws xob rau cua sov thiab cua txias. Yog li ntawd, kev tsim hluav taws xob txuag hluav taws xob yog qhov tseem ceeb heev. Thiab vim tias txheej txheej tiv thaiv cua sov siv dej ua qhov nruab nrab dilution thiab tsis muaj cov kuab tshuaj organic hloov pauv, nws tsis muaj teeb meem rau tib neeg lub cev thiab ib puag ncig; nws cov nqi tsim khoom tsuas yog kwv yees li 1/5 ntawm cov khoom lag luam txawv teb chaws zoo sib xws, thiab nws yog hom tshiab ntawm cov cua sov rwb thaiv tsev Txheej muaj qhov zoo ntawm cov txiaj ntsig kev lag luam zoo, txuag hluav taws xob thiab tiv thaiv ib puag ncig, tiv thaiv tshav kub thiab ua haujlwm yooj yim, thiab lwm yam, thiab lawv tau nyiam ntau thiab ntau tus neeg' kev saib xyuas thiab nyiam. Thiab qhov chaw ntawm qhov cua sov rwb thaiv tsev tiv thaiv txheej txheej no tau hloov pauv los ntawm kev tsim hluav taws xob rwb thaiv tsev mus rau kev tsim hluav taws xob rwb thaiv tsev, los ntawm txheej tuab mus rau txheej tuab txheej rwb thaiv tsev thev naus laus zis, uas tseem yog cov khoom siv hluav taws xob tseem ceeb nyob rau yav tom ntej Ib ntawm cov lus qhia kev txhim kho. Cov nplaim hluav taws xob rwb thaiv tsev txheej txheej siv cov khoom siv sib xyaw ua ke hollow cov khoom siv los ua lub tshuab nqus tsev txheej hauv txheej kom tsim cov txheej txheem cua sov zoo. Tsis tsuas yog nws muaj nws cov thermal ua haujlwm loj, tsis muaj cua sov ua kom sov, tab sis kuj tseem muaj lub siab kub ua kom sov, txo lub tsev raug lub hnub. Kev nqus ntawm cov cua sov ua kom sov ua kom sov ntawm txheej txheej thiab qhov chaw sab hauv, yog li nws tau pom zoo los ntawm cov kws tshaj lij raws li ib qho ntawm cov ntaub ntawv cog lus siv hluav taws xob zoo.
Niaj hnub no, cov khoom siv hluav taws xob rwb thaiv tsev thoob ntiaj teb tab tom tsim los ntawm kev ua kom muaj txiaj ntsig zoo, txuag hluav taws xob, txheej txheej nyias, rwb thaiv tshav kub, thiab tiv thaiv txheej sab nrauv. Thaum tsim cov khoom siv hluav taws xob cua sov tshiab thiab ua raws cov txheej txheem rwb thaiv tsev cua sov thiab txuag hluav taws xob thev naus laus zis, ntau qhov tseem ceeb tau muab tso rau ntawm kev siv hluav taws xob rwb thaiv tsev. Cov khoom siv rwb thaiv tsev tau tsim thiab tsim ua raws li tus qauv tshwj xeeb, thiab siv zog txhim kho kev rwb thaiv tsev kom zoo thiab txo nqi. Kev tshawb fawb txog txheej txheej txheej rwb thaiv tsev rwb thaiv tsev tau tsim tawm hauv tsev thiab txawv teb chaws. Ntau lub tuam txhab hauv Tebchaws Meskas tau tsim cov hluav taws xob rwb thaiv tsev zoo li txheej txheej, xws li SPM Thermo-Shield ntawm Tebchaws Meskas, Ceramic-Npog tsim los ntawm Thermal Protective Systems, thiab Therma-Npog ntawm JH International Thiab lwm yam khoom lag luam. Hom kev tiv thaiv qhov chaw ntim txheej txheej txheej txheej no tau tsim los raws li txoj haujlwm ua haujlwm ntawm NASA los tswj cov cua sov ntawm qhov chaw thauj mus los. Nws yog qhov tsim nyog rau kev txau siab, tsis muaj kuab paug, thiab muaj cua sov tiv taus hluav taws xob zoo, txheej txheej cua sov tiv thaiv, tsis muaj dej thiab tsis xeb thiab lwm yam khoom. Cov khoom tau tig mus rau kev lag luam dav dav thiab pej xeem cov cua sov. Kuj tseem muaj ntau lub tuam txhab kev lag luam hauv kev txhim kho cov ntaub ntawv no, xws li txheej txheej txheej rwb thaiv tsev tiv thaiv hluav taws xob tiv thaiv hluav taws xob, hnub ci tshav kub cuam tshuam cov hluav taws xob rwb thaiv tsev txheej txheej, dej-raws cov pa hluav taws xob rwb thaiv tsev txheej txheej, rwb thaiv tsev tiv thaiv tshav ntuj, txheej txheej rwb thaiv tsev thermal thiab lwm yam . Nws feem ntau yog siv cov khoom siv ua zaj duab xis nrog huab cua tiv taus zoo, muaj zog tiv taus kev laus, muaj zog tiv taus kev laus, muaj zog adhesion thiab elasticity, thiab zoo sib xws nrog rwb thaiv tsev muab tub lim thiab ua kom pom kev zoo. Xaiv lub teeb, hollow, kub, Fillers nrog cov cua sov tiv taus zoo, muaj kev cuam tshuam zoo thiab hluav taws xob, cov hmoov zoo nplua nrog qhov ntsuas siab tsis zoo, ua tiav saum npoo, ua kom sov siab thiab ua kom pom zoo yog tsim raws li cov duab ci ci, thiab ua ke nrog zaj duab xis tsim cov khoom siv hauv paus, lawv tsim kev xa hluav taws xob tsawg. Cov txheej cua sov tuaj yeem txiav tawm qhov hloov pauv cua sov. Cov txheej txheej kub-insulating cov xim pleev xim ua ke nrog cov khoom ntxeem tau tuaj yeem siv rau pleev xim rau ntau qhov chaw xws li cov tsev, tsheb thiab nkoj, cov khoom siv roj av roj av, cov khoom ntim khoom, khaws cia txias, ntim khoom, kav dej thiab lwm yam.
