Mineral Wool yog dab tsi? Cov yam ntxwv yog dab tsi? Nws Yuav Ua Li Cas?
Mar 28, 2022
Mineral ntaub plaub thiab nws cov khoom yog lub teeb, ruaj, tsis-combustible, tsis-rotten, thiab tsis-worm-noj, thiab lwm yam, thiab yog zoo heev thermal rwb thaiv tsev thiab suab-absorbing ntaub ntawv. Cov paj rwb zoo li luv fibers ua los ntawm silicate melts, xws li slag wool, pob zeb ntaub plaub, iav ntaub plaub, thiab ceramics fibers. Cov pob zeb thaum ntxov tshaj plaws tau los ntawm lub qhov tsua ntawm Hawaii hu ua "Fal's hair". Cov uas muaj hlau slag lossis ya tshauv raws li cov ntaub ntawv tseem ceeb yog hu ua slag wool; cov basalt thiab lwm yam pob zeb ua cov ntaub ntawv tseem ceeb yog hu ua "pob zeb wool". Tom qab crushing cov ntaub ntawv raw rau hauv ib tug me me particle, additives thiab lwm yam khoom xyaw rau batching, thiab ces nkag mus rau hauv lub cub tawg kom yaj, tsim paj rwb, thiab pob. Muaj peb hom paj rwb txheej txheem: tshuab tshuab, txoj kev centrifugal thiab centrifugal tshuab tshuab. Mineral wool thiab adhesives tuaj yeem ua rau ntau yam khoom siv ntxhia tom qab tsim, ziab, kho thiab lwm yam txheej txheem.
Mineral wool thiab nws cov khoom muaj cov yam ntxwv ntawm lub teeb yuag, durability, tsis-combustibility, tsis-rot, mildew, thiab tsis muaj kab. Lawv yog cov zoo heev thermal rwb thaiv tsev thiab suab-absorbing ntaub ntawv. fiber ntau txoj kab uas hla ntawm cov ntxhia wool yuav tsum tsis txhob ntau tshaj 9 microns; cov ntsiab lus ntawm cov pob slag yuav tsum tsis pub tshaj 10 feem pua . Qhov ntom ntom ntawm cov paj rwb nyoos yog 50-100 kg / m³, qhov ntom ntom ntawm cov khoom yog 40-200 kg / m³ rau qhov xav tau thiab 70-500 kg / m³ rau lub rooj tsavxwm. Cov thermal conductivity ntawm cov ntaub plaub thiab cov khoom ntawm chav tsev kub yog feem ntau yog 0.041 txog 0.07 W / (m·K). Siv Dry-process mineral wool boards and felts can be used to make composite boards for interior and exterior walls of the buildings, as well as thermal rwb thaiv tsev thiab suab rwb thaiv tsev ntaub ntawv rau lub ru tsev, pem teb, thiab hauv pem teb. Cov boards ntub thiab ib nrab qhuav tuaj yeem siv los ua cov khoom siv suab nrov rau kev kho kom zoo nkauj sab hauv xws li qab nthab thiab phab ntsa hauv pej xeem thiab pej xeem vaj tse. Mineral wool felts, hlab thiab cov laug cam tuaj yeem siv los ua cov ntaub ntawv thermal rwb thaiv tsev rau cov khoom siv thermal thiab cov nroj tsuag tub yees.
Nrog rau qhov tseem ceeb ntawm kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig, cov ntxhia wool, cov qub tub rog ntawm thermal rwb thaiv tsev, plays lub luag haujlwm tseem ceeb hauv kev lag luam tshiab. Nyob rau hauv lub tsev rwb thaiv tsev nyob rau hauv tag nrho viav vias, daim ntawv thov ntawm cov ntxhia ntaub plaub kuj kub, tshwj xeeb tshaj yog nyob rau hauv lub xyoo tsis ntev los no, hluav taws kub nyob rau hauv lub polystyrene ua npuas ncauj board rwb thaiv tsev hom tau tshwm sim los ntawm lub sij hawm, thiab lub tsev rwb thaiv tsev kev lag luam yeej ib txwm txuas qhov tseem ceeb ntawm kev xaiv. ntawm cov ntaub ntawv rwb thaiv tsev. Mineral wool yog siv ntau thiab ntau nyob rau hauv lub tsev rwb thaiv tsev kev lag luam vim nws thermal rwb thaiv tsev nyhuv thiab zoo tsis-combustibility. Daim ntawv thov thev naus laus zis ntawm cov ntaub ntawv tsis-combustible thermal rwb thaiv tsev yog qhov tseem ceeb ntawm kev tshawb fawb thiab kev loj hlob hauv kev lag luam kev txuag hluav taws xob.
Nyob rau hauv lub tsev kev txuag hluav taws xob, kev tsim kho ntawm cov ntxhia wool feem ntau yog muab faib ua ob pawg, ib qho yog qhuav dai, lwm qhov yog pasting, qhuav dai yog tsuas yog rau kev txhawb nqa sab nrauv phab ntsa ntawm lub tsev kom dai iav ntaub thaiv phab ntsa, pob zeb kab hlau rhuav phab ntsa, thiab lwm yam. ., thiab sau lub keel nrog cov ntaub ntawv thermal rwb thaiv tsev. Pasting yog ua raws li kev tsim kho ntawm polystyrene board. Txij li cov pob zeb hauv av board hnyav dua li lub rooj tsavxwm polystyrene thiab muaj lub zog sab hauv me ntsis, muaj ob peb lub ntsiab lus uas yuav tsum tau them sai sai rau hauv kev tsim kho. Ua ntej, galvanized mesh yuav tsum tau siv los tiv thaiv, thiab Nws yog ib qho tsim nyog yuav tsum siv cov ntsia hlau thermal rwb thaiv tsev los kho nws. Rau cov khoom siv ntxhia wool nrog tus kheej qhov hnyav loj, cov txheej txheem tsim kho yuav tsum tau txiav txim siab kom tsis txhob deformation tshwm sim los ntawm tus kheej qhov hnyav.
