Umgangatho webhodi yokugquma uboya kufuneka ube nezi mpawu zilandelayo:

Okokuqala, i-conductivity ephantsi ye-thermal.I-conductivity ye-thermal iyisalathisi esibalulekileyo sokulinganisa ukusebenza kwezinto zendlu ezenziwe ngaphambili.I-thermal conductivity incinci, kwaye ibhodi yoboya be-thermal yokugquma i-thermal esebenza ngcono yokugquma i-thermal ifanelekile ngokugqithiswa kwemathiriyeli yamandla amancinci.

Okwesibini, i-coefficient yokufunxa isandi.Inesiphumo esihle sokufunxa isandi.Ibhodi yoboya be-thermal yokugquma i-rock ikakhulu ixhomekeke kubuninzi beyunithi nganye yendawo.Okukhona uxinaniso lukhulu, kokukhona ukufunxeka ngcono kwesandi.

Inqaku lesithathu kukuba kufuneka libe ne-hygroscopicity ephantsi.Emva kokufunxa amanzi, umphumo wokugcinwa kobushushu bezinto zokugcina ukushisa ziya kuncitshiswa kakhulu, kuba amanzi ane-conductivity ephezulu ye-thermal.Ngoko ke, kucetyiswa ukuba abathengi bakhethe ibhodi yoboya be-rock engenamanzi.

I-acidity coefficient ngumlinganiselo wokomelela kweekhemikhali zoboya bamatye.Ingumlinganiselo we-mass sum of silica kunye ne-alumina ukuya kwisixa se-calcium oxide kunye ne-magnesium oxide kwi-fiber composition.I-acidity coefficient sisalathiso esibalulekileyo sokuvavanya umgangatho weemveliso zoboya bamatye.I-acidity coefficient iphezulu, ukumelana nemozulu kulungile kwaye ubomi bude.Ngexesha elifanayo, i-coefficient ye-acidity ikwayindlela ebalulekileyo yokwahlula phakathi koboya be-rock kunye noboya be-slag.Izinto eziluhlaza zoboya be-slag zisekelwe kwi-slag kunye ne-acidity coefficient ingaphantsi kwe-1.5, kwaye i-rock wool yoboya isekelwe kwi-basalt, kunye ne-acidity coefficient ≥ 1.6.

Umbala wosinga loboya belitye olahlelwa ngaphandle bubushushu obuphezulu uqhele ukuba mhlophe.Umbala weemveliso zoboya bamatye ngokuqhelekileyo butyheli-luhlaza.Kungenxa yokuba i-rock wool fiber yongeza i-organic phenolic adhesive ukuba yenziwe kwimilo ethile kunye namandla athile, olu hlobo lokuncamathelisa lubhakwa kwi-300-400 ° C kwaye lusabela kunye nokwakheka kwemichiza yoboya bamatye ukutshintsha umbala woboya belitye. ifayibha.
