Maminolo ubweya: ntchito ndi GOST

Kutchuka yaikulu ya wools mchere makamaka chifukwa ndalama zawo otsika ndi ntchito zabwino. Nkhanizi angagwiritsidwe ntchito kutchinjiriza matenthedwe zosiyanasiyana ziwembu - makoma, denga ndi pansi m'nyumba, mapaipi, heaters, etc ...

The ndondomeko ya kulenga

Monga zopangira mu kupanga zinthu ngati mchere ubweya slabs ntchito osungunula chiphala mwala, galasi, kuphulika ng'anjo slag. Izi otentha viscous mankhwala umaperekedwa mu centrifuge yapadera, imene (chifukwa cha kuwomba mphepo) adziwonetsa misa fibrous. binders Komanso tikuuzidwa mu izo. Kawirikawiri maudindo awo ndi utomoni phenol-formaldehyde. Kenako yomata "ubweya" umadza pansi odzigudubuza, chimene chinapanga wosanjikiza yosalala izo. Pa chomaliza, chuma kudula kwa mbale anakhumba kukula.

ulusi mchere ubweya akhoza anakonza m'njira wachisokonezo, ndi perpendicular kwa wina ndi mzake. Njira yamasika amatchedwa laminalnym chuma ali ndi osalimba kwambiri ndi digiri ya madutsidwe ikukhudzana ali mphamvu yapamwamba. Nthawi zina mchere ubweya slabs glued kuti mbali imodzi ya wandiweyani zojambulazo zotayidwa.

Mlingo wa moto kukaniza

Ubwino waukulu wa nkhosa mchere poyerekeza insulators ena amaona combustibility ake. Zotheka kugwiritsa ntchito zinthu izi kwa chimateteza pamalo amene kutentha ukufika madigiri 400 Celsius. N'chifukwa chake matabwa mchere abwino insulator kwa boilers ndi ng'anjo a mitundu yosiyanasiyana. Kusungunuka basalt ulusi anayamba pokhapokha maola awiri kukhudzana ndi kutentha madigiri 1000. Ichi ndi chithunzi chidwi kwambiri. Pankhani kutentha yozungulira, ndiye popanda vuto chuma chingathe kupirira madigiri 750. Gulu la combustibility matabwa mchere - KM0. Mu mitundu zojambulazo - KM1.

Mlingo wa madutsidwe matenthedwe

Cholinga cha ubweya mchere - kuteteza nyumba, zida ndi mauthenga ochokera kwa kuzizira. Yovomerezeka matenthedwe madutsidwe wa nkhaniyi anatsimikiza ndi GOST 4640-2011. mlingo izi mosiyanasiyana malingana ndi kutentha yozungulira ndipo kungakhale kuchokera 0,038 W / (MK) pa kutentha kwa madigiri 10 kuti 0,070 W / (MK) pa madigiri 300. Choncho, luso kusunga kutentha, chuma kuposa insulators zambiri zamakono. Khalidwe limeneli chifukwa kapangidwe porous ndi ambiri zigawo mpweya.

kachulukidwe

Izi chuma index monga matabwa mchere ubweya zokutira zitsulo, siyana mkati mwachilungamo lalikulu (30-220 makilogalamu / mamita ^3). The apamwamba osalimba pa mbale, m'pamenenso anagawira katundu zikhoza kupirira. Pakuti chizindikiro ichi, ubweya mchere akhoza ziri zimagawidwa m'magulu atatu:

• Low kachulukidwe (30-50 makilogalamu / mamita ^3). ubweya Izi makamaka ntchito kwa kutchinjiriza matenthedwe wa pamalo yopingasa.
• Sing'anga osalimba (60-75 makilogalamu / mamita ^3). mtundu nthawi zambiri ntchito kupeza onse a makhazikitsidwe luso.
• Mkulu osalimba (80-175 makilogalamu / mamita ^3). mbale amenewa angagwiritsidwe ntchito makoma chimateteza mkati kapena nyumba kunja.
• kwambiri kachulukidwe (180-200 makilogalamu / mamita ^3). mtundu kawirikawiri ntchito kutchinjiriza matenthedwe za madenga.

The kachulukidwe zakuthupi ngati mchere ubweya slab, - chizindikiro liwulo luso wawo wokha kupirira katundu. Mlingo wa madutsidwe matenthedwe iwo ali pafupifupi ziribe mphamvu.

watertight

Low kukana Zakudza madzi - mmodzi wa zovuta pang'ono, amene ubweya mchere. GOST kutsimikizira kugwilizana ndi specifications nkhani mawu kukaniza madzi amafuna mayesero yeniyeni. Kotero m'malo osiyanasiyana mumtengo mbale (20-30 magalamu). Komanso iwo anayikidwa mu mbale zadothi ndi calcined pa kutentha madigiri 600 kuchotsa zosafunika organic. Unyinji ndiye n'kukhala ngati ufa, wothira madontho ochepa a Mowa, kenako Kuwonjezera asidi pang'ono hydrochloric. Komanso elekitirodi mphamvu ndi adatchithisira pH mita. Patapita mphindi khumi oyambitsa, pH anali anayeza mankhwala. Madzi kukana zakuthupi anatsimikiza ndi chiyerekezo cha pH lapansi.

Maminolo ubweya (GOST Mzimuyo madzi kukana kwawo osapitirira 4.7 pH) amamudziwa kuyamwa madzi, motero kutaya ake katundu kutentha chimateteza. Komabe, mlingo wa chinyezi ndi kulemera sayenera upambana 1%. Kuonjezera kukhazikika chinyezi chuma impregnated ndi hydrophobizing wapadera.

nthunzi ya madzi permeability

Ubwino wa zinthu ngati ubweya mchere, mwina monga kuphatikizapo luso la kudutsa molekyulu madzi. Maminolo ubweya nthunzi permeability koyefishienti ndi 480 * 10-6 g / (h * mamita * Pa). Poyerekeza ndi zina heaters chi ndi yayikulu.

Location CHIKWANGWANI

Maminolo ubweya ndi makonzedwe wachisokonezo ulusi ali ndi mphamvu yokoka zenizeni mu 120-160 makilogalamu / ^M3 ndi mphamvu pa kucha 10 kPa. mtundu kawirikawiri opangidwa ku slabs kutalika kwa 120-160 masentimita ndi m'lifupi mwake 50-60 cm. Basalt ubweya ndi makonzedwe perpendicular ulusi (nyengo) osiyana yeniyeni kulemera kwa 80-120 makilogalamu / ^M3 ndipo misozi mphamvu ya 80 kPa pa chotupa. The miyeso ndi zigawo zosiyanasiyana izi ndi 120 × 20 cm. The makulidwe a ubweya mchere zimasiyanasiyana pakati 30-100 mm.

Kwambiri zopangidwa otchuka

Makamaka mu Russia kwa chimateteza nyumba zikuluzikulu ntchito mchere ubweya mtundu "Technonikol". wopanga ici ulikubala kwambiri apamwamba zakuthupi ndi mfundo zabwino kwambiri GOST. Komanso, amaona kuti kukhala mwayi undoubted wa mtengo wotsika.

Mofanana otchuka mchere Rockwool slab. Zamgululi ku wopanga izi angagwiritsidwe ntchito kutchinjiriza matenthedwe wa zinthu mwamtheradi aliyense moyenera ndipo zida mphamvu. Basalt ubweya wa mtundu limeneli likupezeka zamitundu yonse ndi zolemera.

Kuchuluka kwa ntchito

Ntchito mchere ubweya slabs kwa kutchinjiriza matenthedwe:

• Pansi;
• podutsa mpweya pamakoma;
• wapakamwa pulasitala;
• madenga;
• mkati malinga ndi partitions;
• kudenga;
• mapaipi;
• ng'anjo ndi m'chumunicho;
• boilers;
• zida kupanga ndi zina zotero. d.

Maminolo ubweya - kutchinjiriza ndi kothandiza kwambiri ndi odalirika. Kuphatikiza ntchito kwambiri ndi mtengo wotsika kuvumbitsira kwambiri wotchuka pakati kutukula munthu, komanso makampani akuluakulu mafakitale.
