Mineral uvolo: ukusebenza kanye GOST

Ukuthandwa omkhulu ka wools amaminerali ngokuyinhloko ngenxa yokubiza kwalo ongaphakeme kanye nokusebenza kakhulu. Lokhu kwaziswa kungasetshenziswa ukuze zihlale zifudumele ezihlukahlukene imiklamo - izindonga, ophahleni kanye phansi kwezindlu zangasese, amapayipi, ama-heater, njll ...

Inqubo yokudala

Njengoba impahla eluhlaza enkulu ekwakhekeni elinama ezifana amaminerali uvolo slabs wasebenzisa umfanekiso oncibilikisiwe rock mlilo, ingilazi, ngokufutha komoya esithandweni slag. Le into eshisayo viscous ihlinzekwa endaweni Centrifuge ekhethekile, lapho (ngenxa afuthwe ngomoya) uguqulwe mass fibrous. Ngaphezu kwalokho binders yethulwe kuwo. Ngokuvamile izindima zabo kukhona resin phenol-formaldehyde. Okulandelayo okunamathelayo "uvolo" iza ngaphansi ezinamasondo, ukwakha ungqimba abushelelezi ke. Ngesikhathi esigabeni sokugcina, le nto ukusika usayizi oyifunayo amapuleti.

Imicu yotshani amaminerali uvolo zingahlelwa ngendlela kunezinxushunxushu futhi perpendicular nomunye. Inketho yokugcina libizwa laminalnym impahla lunesibalo enkulu kanye degree of conductivity ezishisayo, buyimfanelo enamandla okusezingeni eliphezulu. Ngezinye izikhathi amaminerali uvolo slabs ethe njo kolunye uhlangothi obukhulu aluminium ucwecwe.

I degree of umlilo ukumelana

Inzuzo enkulu amaminerali uvolo njengoba kuqhathaniswa nezinye insulators kubhekwa combustibility yayo. Kungenzeka ukusebenzisa lolu zethu ezingokwenyama nangokuvikela evele kabani lokushisa ifinyelela degrees 400 Celsius. Yingakho amabhodi amaminerali kukhona yisivikelo ekahle boilers futhi amaziko ezinhlobo ezehlukene. Ukuqeda basalt Imicu yotshani uqale kuphela ngemuva kwamahora amabili ukuchayeka lokushisa 1000. Lena sibalo umxhwele kakhulu. Ngokuphathelene ezingeni lokushisa elifanele-ke ngaphandle umonakalo okokusebenza zingamelana 750 degrees. Iqembu amabhodi amaminerali combustibility - KM0. Ngo ucwecwe izinhlobo - KM1.

I degree of conductivity ezishisayo

Injongo eyinhloko noboya amaminerali - ukuvikela amakhaya, imishini kanye nezokuxhumana ngenxa yamakhaza. Ngendlela Ayamukelayo conductivity ezishisayo kwale nto kunqunywa GOST 4640-2011. Lokhu kulinganisela iyahlukahluka kuye ngokuthi ezingeni lokushisa elifanele futhi kungaba kusuka 0,038 W / (MK) ngesikhathi lokushisa 10 kuya 0,070 W / (MK) ngesikhathi degrees 300. Ngakho, ikhono ukugcina ukushisa, le nto luphakeme insulators eziningi zanamuhla. Lokhu izinga kungenxa isakhiwo ukungena nakwamanye amazwe ngenombolo enkulu emoyeni izingqimba.

inhlanganiso

Lokhu kwaziswa Inkomba ezifana amaminerali uvolo ekuvikeleni amabhodi, ziyahlukahluka ngaphakathi kahle esikhulu (30-220 kg / m ^3). Ayanda kwabantu ngesikhathi ipuleti, kulapho basakaza umthwalo kungaba ukumelana. Ngenxa yalesi inkomba, noboya amaminerali kungenziwa cishe oluthathwa ngezigaba ezintathu:

• inhlanganiso okuphansi (30-50 kg / m ^3). Lokhu uvolo ikakhulukazi esetshenziselwa zifudumele ezishelelayo ovundlile.
• inhlanganiso okulingene (60-75 kg / m ^3). Lolu hlobo uvame esetshenziswa ukwehlukanisa zonke izinhlobo ukufaka lobuchwepheshe.
• inhlanganiso High (80-175 kg / m ^3). amapuleti ezinjalo ingasetshenziswa izindonga nangokuvikela ngaphakathi noma izakhiwo ngaphandle.
• high density kakhulu (180-200 kg / m ^3). Lolu hlobo ngokuvamile esetshenziselwa zifudumele uphahla.

I kwabantu of a impahla ezifana amaminerali uvolo setshe, - kube inkomba ngokuchaza ikhono lazo ukumelana umthwalo kuphela. I degree of conductivity ezishisayo it has cishe awukho umphumela.

amanzi angangeni

Ukumelana okuphansi ukuze amanzi Ukungena - omunye nemiphumela ethile engathandeki ezimbalwa, ezithinta amaminerali uvolo. GOST ukuqinisekisa ukuhambisana nezimiso impahla ngokuya ukumelana namanzi idinga ukuhlolwa ethize. ipuleti Ngakho ezivela ezindaweni ezahlukene amasampuli (20-30 amagremu). Ngaphezu kwalokho ezibekwe isidlo zobumba futhi calcined at lokushisa 600 ukuze akhiphe amanyela organic. Ungqimba ke kutsho lube impuphu, oswakanyiswe amaconsi ambalwa ethanol, kulandele ukwengeza hydrochloric acid kancane. Ngaphezu kwalokho, umthamo electrode lehliselwa imitha pH. Ngemva kwemizuzu eyishumi sibhebhezela, pH sasibalwa izidakamizwa. Ukumelana Water zalezi zinto kunqunywa isilinganiso pH.

Mineral uvolo (GOST inquma ukumelana kwabo amanzi ezingekho ngaphezu 4.7 pH) sasivumela ukuncela kahle amanzi, ngaleyo ndlela alahlekelwe ezinye yayo izakhiwo ukushisa-nangokuvikela. Nokho, izinga nomswakama ngesisindo kumele singeqi 1%. Ukuze uthuthukise uzinzo umswakama indaba afuthwe ngesibulali hydrophobizing ekhethekile.

umhwamuko permeability

Izinzuzo impahla ezifana amaminerali uvolo, ingase ihlanganise kuhlanganise nekhono ukuba adabule i-molecule yamanzi. Mineral uvolo umusi permeability Coefficient kuyinto 480 * 10-6 g / (h * m * Pa). Uma kuqhathaniswa nezinye izinto zokulawula izinga lokushisa endlini wesimanje yilona eliphezulu ukuwedlula wonke.

Indawo fibre

Mineral uvolo nge ilungiselelo esingalawuleki kwezintambo zesivikelo sesifuba has a gravity ethize ku 120-160 kg / ^M3 kanye namandla e-break 10 KPA. Lolu hlobo ngokuvamile akhiqizwa slabs ubude 120-160 cm kanye ububanzi 50-60 cm. Basalt uvolo nge ilungiselelo perpendicular imicu (inkathi) ezahlukene isisindo ezithile 80-120 kg / ^M3 kanye namandla izinyembezi 80 KPA at ukudabuka. Ubukhulu izingqimba lokhu ezihlukahlukene kukhona 120 x 20 cm. Ezinkulu zenza ukuthi ungangeni uvolo amaminerali uyahluka 30-100 mm.

brand edume kakhulu

Isikhathi esiningi eRussia nangokuvikela izingxenye isakhiwo esisetshenziselwa amaminerali uvolo brand "Technonikol". Lokhu umkhiqizi ukhiqiza kakhulu eliphezulu impahla namazinga omuhle kakhulu GOST. Ngaphezu kwalokho, kubhekwa inzuzo undoubted ka eziphansi.

amaminerali ngokulinganayo ethandwa Rockwool setshe. Imikhiqizo kusukela kule nomkhiqizi ingasetshenziswa zifudumele ka ngokuphelele yimuphi izakhi ezakhayo futhi imishini amandla. Basalt uvolo yalesi brand itholakala bonke osayizi kanye izinsimbi.

Ububanzi bokusebenzisa

Ezisetshenzisiwe amaminerali uvolo slabs ngoba zihlale zifudumele:

• emabhilidini;
• mbumbulu umoya;
• olungaphambili lwesonto usimende;
• uphahla;
• ngaphakathi kwezindonga futhi ngodonga;
• Uphahla lwangaphakathi;
• amapayipi;
• amaziko kanye kushimula;
• boilers;
• imishini ukukhiqizwa nokunye. d.

Mineral uvolo - ukwahlukanisa kuyinto esebenza kahle kakhulu futhi enokwethenjelwa. Inhlanganisela ukusebenza kakhulu nge eziphansi kwenza kube yathandeka kakhulu phakathi Onjiniyela ngabanye, kanye izinkampani ezinkulu ezimbonini.
