Mineral wool: kev ua tau zoo thiab lub GOST

Cov loj loj tej chaw ntawm mineral wools yog feem ntau vim lawv cov uas tsis muaj nqi thiab zoo heev zoo. Qhov no cov ntaub ntawv uas yuav siv tau rau thermal rwb thaiv tsev ntawm ib tug ntau yam ntawm designs - phab ntsa, ru tsev thiab pem teb ntawm private tsev, kav dej, cua sov, thiab lwm yam ...

Tus txheej txheem ntawm kev tsim

Raws li nyoos khoom nyob rau hauv qhov siv thiab ua ib cov ntaub ntawv xws li mineral wool slabs siv molten volcanic pob zeb, iav, moj tej tawg cub tawg slag. Qhov no kub khov yam khoom uas yog nkag rau hauv ib tug tshwj xeeb centrifuge, nyob rau hauv uas (raws li ib tug tshwm sim ntawm tshuab cua) yog hloov mus rau hauv ib tug fibrous loj. Ntxiv binders yog nkag tau rau hauv nws. Feem ntau lawv tus cwj pwm yog cov phenol-formaldehyde cob. Tom ntej no nplaum "wool" los nyob rau hauv lub chais, txoj kev ua ib tus txheej ntawm nws. Thaum lub theem kawg, cov khoom yog txiav mus rau qhov kev kawm loj daim hlau.

Mineral wool fibers yuav teem nyob rau hauv ib tug chaotic yam, thiab lawv mus rau txhua lwm yam. Cov yav tas kev xaiv no yog hu ua laminalnym khoom muaj ib tug ntau dua kev ceev thiab degree ntawm thermal conductivity, muaj siab zog. Tej zaum mineral wool slabs glued mus rau ib sab ntawm cov tuab txhuas ntawv ci.

Lub degree ntawm hluav taws kuj

Lub ntsiab kom zoo dua ntawm mineral wool yog muab piv rau lwm yam insulators yog suav tias yog nws cov combustibility. Tau siv cov khoom siv no rau insulating chaw uas nws kub nce mus txog 400 degrees Celsius. Uas yog vim li cas lub laug cam mineral yog zoo tagnrho insulator rau boilers thiab furnaces ntawm ntau hom. Melting basalt fibers pib tsuas yog tom qab ob teev raug mus rau ib tug kub ntawm 1000 degrees. Qhov no yog ib tug heev impressive duab. Nrog kev xav txog cov ambient kub, ces tsis muaj kev tsim txom cov khoom yuav mas 750 degrees. Pab pawg neeg cov combustibility mineral boards - KM0. Nyob rau hauv ntawv ci ntau yam - KM1.

Lub degree ntawm thermal conductivity

Lub hom phiaj tseem ceeb ntawm cov mineral wool - mus tiv thaiv tsev, cov khoom thiab kev sib txuas lus los ntawm tus mob khaub thuas. Cov thermal conductivity ntawm no cov ntaub ntawv uas yog txiav txim los ntawm lub GOST 4640-2011. Qhov no tus nqi txawv nyob ntawm seb lub ambient kub thiab yuav ua tau los ntawm 0,038 W / (Mk) nyob rau hauv ib tug kub ntawm 10 degrees rau 0,070 W / (Mk) nyob rau hauv 300 degrees. Yog li, muaj peev xwm khaws thaum tshav kub kub, qhov no cov ntaub ntawv uas yog superior rau ntau niaj hnub insulators. Qhov no zoo yog vim lub ntxeem tau qauv nrog ib tug loj tus naj npawb ntawm cov huab cua khaubncaws sab nraud povtseg.

ceev

Qhov no index khoom xws li mineral wool insulating cov laug cam, yuav txawv tsis pub dhau haum loj (30-220 kg / m ^3). Lub siab dua tus ceev ntawm lub phaj, qhov ntau faib lub load nws yuav mas. Rau qhov ntsuas no, cov mineral wool yuav roughly txwv kom muab zais rau hauv peb pawg:

• Tsis tshua muaj ceev (30-50 kg / m ^3). Qhov no wool yog tsuas yog siv rau thermal rwb thaiv tsev ntawm kab rov tav chaw.
• Medium ceev (60-75 kg / m ^3). Cov hom yog feem ntau siv rau cais tawm tag nrho cov xaiv ntawm kev sib.
• High ceev (80-175 kg / m ^3). Tej daim hlau yuav siv tau rau lub insulating phab ntsa hauv los yog sab nraum tsev.
• Heev kev kub ceev (180-200 kg / m ^3). Cov hom yog feem ntau yog siv rau thermal rwb thaiv tsev ntawm ru tsev.

Cov kev ceev ntawm ib cov khoom xws li mineral wool slab, - ib tug qhia defining tsuas yog lawv muaj peev xwm los mus tiv load. Lub degree ntawm thermal conductivity nws twb yuav luag tsis ntxim.

watertight

Tsis tshua muaj kuj mus dej allergic - ib qho ntawm ob peb drawbacks, uas muaj mineral wool. GOST kom paub tseeb raws li cov ntaub ntawv uas specifications nyob rau hauv cov nqe lus ntawm kuj mus dej yuav tsum tau kev ntsuam xyuas. Yog li los ntawm ntau qhov chaw sampled phaj (20-30 grams). Ntxiv lawv muab tso nyob rau hauv ib tug iav tais thiab calcined ntawm ib tug kub ntawm 600 degrees kom tshem tawm organic impurities. Lub loj yog ces av mus rau ib tug hmoov, moistened nrog ib tug ob peb tee ntawm ethanol, ua raws li los ntawm tas li ntawd ntawm ib tug me ntsis hydrochloric acid. Ntxiv mus, lub electrode peev xwm uas nws txo qis pH 'meter'. Tom qab kaum feeb stirring, pH yog ntsuas substance. Dej kuj ntawm cov khoom yog txiav txim los ntawm qhov nruab nrab ntawm lub pH.

Mineral wool (GOST txiav txim lawv cov dej kuj tsis ntau tshaj li 4.7 pH) haum zoo nqus dej, yog li poob ib co ntawm nws cov tshav kub-insulating zog. Txawm li cas los, cov neeg kawm ntawv ntawm av noo by luj yuav tsum tsis txhob ntau tshaj 1%. Yuav kom txhim kho txoj kev stability rau dej cov khoom yog impregnated nrog tshwj xeeb hydrophobizing.

dej vapor permeability

Qhov zoo ntawm ib tug khoom xws li mineral wool, tej zaum yuav muaj xws li xws li muaj peev xwm kis tau los ntawm ib tug dej molecule. Mineral wool vapor permeability coefficient yog 480 * 10-6 g / (h * m * Pa). Piv nrog rau lwm kawm tso cua sov yog lub siab tshaj plaws.

Qhov chaw fiber

Mineral wool nrog ib tug chaotic arrangement ntawm lub fibers muaj ib tug kev nqus nyob rau hauv lub 120-160 kg / ^m3 thiab ib lub zog ntawm so ntawm 10 kPa. Qhov no zoo feem ntau yog ua nyob rau hauv slabs ntev ntawm 120-160 cm thiab ib tug dav ntawm 50-60 cm. Basalt wool nrog ib tug perpendicular arrangement ntawm fibers (caij) sib txawv kev luj ntawm 80-120 kg / ^m3 thiab los kua muag zog ntawm 80 kPa ntawm kev sib tawg. Lub qhov ntev ntawm cov phiaj no ntau yam yog 120 x 20 cm. Cov thickness ntawm cov mineral wool nws sib txawv 30-100 hli.

Feem ntau cov nrov hom

Feem ntau nyob rau hauv Russia rau insulating tsev Cheebtsam siv mineral wool hom "Technonikol". Qhov no chaw tsim tshuaj paus ua heev-zoo khoom uas muaj yav tom ntej cov qauv ntawm GOST. Nyob rau hauv tas li ntawd, nws yog pom tias yuav ua tau ib tug undoubted kom zoo dua ntawm tus nqi qis.

Attendance nrov mineral Rockwool slab. Cov khoom siv los ntawm no chaw tsim tshuaj paus yuav siv tau rau thermal rwb thaiv tsev ntawm kiag li tej constructive ntsiab thiab lub zog cuab yeej siv. Basalt wool ntawm no hom yog muaj nyob rau hauv tag nrho cov ntau thiab tsawg thiab tes taw hnyav li.

Scope ntawm kev siv

Siv mineral wool slabs rau thermal rwb thaiv tsev:

• plag tsev;
• ventilated facades;
• facade plaster;
• ru tsev;
• hauv lub phab ntsa thiab partitions;
• ceilings;
• pipelines;
• furnaces thiab chimney;
• boilers;
• ntau lawm cov khoom thiab hais txog. d.

Mineral wool - rwb thaiv tsev yog ib tug heev npaum thiab txhim khu kev qha. Lub ua ke ntawm zoo heev zoo nrog cov uas tsis muaj nqi ua rau nws tsis tshua muaj nrov ntawm ib tug neeg developers, raws li zoo raws li nyob rau hauv loj industrial tuam txhab uas muag.
