Izinga le-rock wool insulation board kufanele libe nalezi zimpawu ezilandelayo:

Okokuqala, conductivity ephansi ezishisayo.I-conductivity ye-thermal iyinkomba ebalulekile yokulinganisa ukusebenza kwempahla yendlu eyenziwe ngaphambilini.I-thermal conductivity incane, futhi ibhodi le-thermal insulation rock wool elinokusebenza okungcono kwe-thermal insulation lifaneleka ngokudluliswa kwempahla yamandla amancane.

Okwesibili, i-coefficient yokumuncwa komsindo.Inomphumela omuhle wokumunca umsindo.Ibhodi loboya be-rock insulation elishisayo lincike ikakhulukazi kubuningi beyunithi ngayinye.Uma kukhulu ukuminyana, ukumunca kangcono komsindo.

Iphuzu lesithathu ukuthi kufanele libe ne-hygroscopicity ephansi.Ngemuva kokumunca amanzi, umphumela wokugcinwa kokushisa kwezinto zokulondoloza ukushisa uzoncishiswa kakhulu, ngoba amanzi ane-conductivity ephakeme yokushisa.Ngakho-ke, kunconywa ukuthi amakhasimende akhethe ibhodi loboya bedwala elingangeni manzi.

I-acidity coefficient iyisilinganiso sokuqina kwamakhemikhali e-rock wool.Kuyisilinganiso sobuningi besamba se-silica ne-alumina esilinganisweni se-calcium oxide ne-magnesium oxide ekubunjweni kwefiber.I-acidity coefficient iyinkomba ebalulekile yokuhlola ikhwalithi yemikhiqizo ye-rock wool.I-acidity coefficient iphezulu, ukumelana nesimo sezulu kuhle futhi impilo yinde.Ngesikhathi esifanayo, i-acidity coefficient iyindlela ebalulekile yokuhlukanisa phakathi koboya bedwala noboya be-slag.Impahla eluhlaza yoboya be-slag isekelwe ku-slag futhi i-acidity coefficient ingaphansi kuka-1.5, futhi impahla eluhlaza yoboya bedwala isekelwe ku-basalt, kanye ne-acidity coefficient ≥ 1.6.

Umbala we-rock wool fiber ophonswa izinga lokushisa eliphezulu ngokuvamile umhlophe-mhlophe.Umbala wemikhiqizo ye-rock wool ngokuvamile uphuzi-luhlaza.Kungenxa yokuthi i-rock wool fiber ingeza ingcina ye-organic phenolic ukuze yenziwe ibe yisimo esithile namandla athile, lolu hlobo lwe-adhesive lubhakwa ku-300-400 ° C futhi lusabela ngokubunjwa kwamakhemikhali woboya bedwala ukushintsha umbala woboya bedwala. i-fiber.
