- Yintoni umbandela ofunxa isandi
Izixhobo ezifunxa isandi zinokwenza nayiphi na into efunxa isandi, kodwa iqondo lokufunxa lihluke kakhulu. Uninzi lwazo zizinto ezikhululekileyo kunye nezixhobo, ezifana noboya be-slag, iingubo, njl. Kwaye i-pores ininzi imingxuma evulekileyo enxibelelana enye kwenye ngaphakathi, ephantsi kwe-friction kunye ne-viscous resistance ye-molecules zomoya, kunye nokungcangcazela komatshini wemicu emihle, ukuze amandla omsindo aguqulelwe amandla obushushu.
- Iintlobo zemathiriyeli efunxa isandi
Izinto ezifunxa isandi ngokubanzi zahlulwe zibe ziintlobo ezintathu: uhlobo lwefayibha, uhlobo lwefoam, kunye nohlobo lwamasuntswana.
Iiphaneli eziqhelekileyo zokufunxa isandi kwiimarike ziquka iipaneli zokhuni ezifunxa isandi, iipaneli ezifunxa isandi kwilaphu, iipaneli ezifunxa isandi esinegwebu, iipaneli zokufunxa izandi zefiber yepolyester, iipaneli zoboya zomthi ezifunxa isandi, njl.
Izixhobo zodidi lwefayibha zohlulwe zibe ziindidi ezimbini: iifiber eziphilayo kunye nemicu ye-inorganic. Iintsinga ze-Organic zenziwe ikakhulu nge-cotton yokugquma isandi, uboya be-slag, uboya beglasi, uboya belitye, njl.njl. Phakathi kwazo, uboya beglasi bunokusetyenziswa ukwenza imathi yeglasi. I-cotton ye-sound insulation yeyona nto isetyenziswa ngokuqhelekileyo i-sound-absorbent material, kwaye izibonelelo zayo zezi: ezingatshiyo, ezikwazi ukumelana nobushushu, zikwazi ukumelana ne-corrosion, njl.
Izixhobo zokufunxa isandi sohlobo lwegwebu zineengenelo zobuninzi obuncinci, ukuhanjiswa kwe-thermal, kunye nokuthambile. Ukuba awonelanga, kulula ukuguga kwaye akakwazi ukumelana nomlilo.
Izinto zegranular zinokuthintela ukufuma, ukugcinwa kobushushu, ukuxhathisa kwe-corrosion kunye nokunye.
- Umgaqo wezinto ezifunxa isandi
Izinto ezifunxa isandi (izinto ezifunxa isandi): Nayiphi na imathiriyeli inokufunxa isandi, kodwa iqondo lokufunxa lahluke kakhulu. Ngokubanzi, imathiriyeli ene-avareji yomlinganiso wokufunxa isandi ongaphezulu kwe-0.2 kwezi frikhwensi ezintandathu zingentla zidweliswe njengemathiriyeli efunxa isandi. Izixhobo ezifunxa isandi Uninzi lwezixhobo ezifunxa isandi zikhululekile kunye nezixhobo ezinqabileyo, ezifana noboya be-slag kunye neengubo. Isixhobo salo sokufunxa isandi kukuba amaza omsindo angena nzulu kwiimbobo zezinto, kwaye iipores ziyimingxuma evulekileyo enxibelelana ngaphakathi ngaphakathi. Baphantsi koxinzelelo kunye nokuxhathisa kwe-viscous yeemolekyuli zomoya, kunye nokungcangcazela koomatshini bemicu emihle, ngaloo ndlela beguqula amandla omsindo abe ngamandla obushushu. I-coefficient yokufunxa isandi yolu hlobo lwezixhobo ezifunxa isandi ngokubanzi zikhula ngokuthe ngcembe ukusuka kwi-frequency ephantsi ukuya kwi-frequency ephezulu, ngoko ke isiphumo sokufunxa isandi kwi-frequency ephezulu kunye ne-intermediate frequency ingcono. Umgaqo osebenzayo wezinto ezifunxa isandi: isandi sisuka kwintshukumo yezinto, ebangela ukungcangcazela komoya osecaleni kwenze amaza esandi, kwaye isasazeke kwindawo yomoya. Izinto ezifunxa isandi: Xa isandi sigqithiselwa kumphezulu wesixhobo secandelo, inxalenye yamandla esandi ibonakala, inxalenye yayo ingena kwizinto eziphathekayo, kwaye inxalenye yayo ibangelwa kukungcangcazela kwesixhobo secandelo okanye ukungqubana nesixhobo esisingqongileyo xa isandi sisasaza kuyo. Amandla esandi aguqulwa abe ngamandla obushushu, kwaye amandla esandi ayalahleka, oko kukuthi, isandi sitsalwa yimathiriyeli. I-coefficient yokufunxa isandi: Ukusebenza kwesandi sokufunxa izinto kubonakaliswa yi-coefficient yokufunxa isandi α. Α sisixa-mali selahleko coefficient Eab/E0 kunye ne-coefficient yokungena Ethr/E0. Ukusebenza kwesandi sokufunxa kwesixhobo akuhambelani kuphela nesakhiwo, ubukhulu kunye neempawu zomphezulu wezinto ngokwazo, kodwa zihambelana nesalathiso sesiganeko kunye nokuphindaphinda kwesandi.
- Ukusetyenziswa kwezinto ezifunxa isandi kulwakhiwo
(1) Lawula ixesha lokuphindaphinda komgangatho wesandi seeholo, ezinje ngeeholo zeekonsathi, iithiyetha, iistudio zokurekhoda, iistudio, amagumbi okuvavanya, amagumbi eenkomfa, iiholo ezinemisebenzi emininzi, iigymnasium, iiauditorium, njl. Ngokubanzi, ixesha elifanelekileyo lokuphindaphinda lifumaneka ngokukhetha nokulungiselela izixhobo ezifanelekileyo zokufunxa isandi.
(2) Kwizakhiwo zezithuthi zikawonke-wonke, njengeholo yokulinda yesikhululo seenqwelo-moya, igumbi lokulinda lesikhululo, negumbi lokulinda lesikhululo seenqwelomoya. Ngenxa yokuba kuyimfuneko ukusasaza ngokuqhubekayo ulwazi olufana nokuhamba, ukufika okanye ukulibaziseka kwexesha leenqwelomoya kunye nezitimela kunye neenqanawa. Izinto ezithatha isandi ezifana ne-foam zinokucwangciswa ngokufanelekileyo kwisilingi kunye neendonga. Kwelinye icala, inokuphucula ukucaca kolwazi losasazo; kwelinye icala, inokunciphisa ingxolo yabakhweli kwaye yenze imekobume izolile.
(3) Ukuphelisa iziphene zomgangatho wesandi ezifana ne-echo kunye nokugxila kwisandi eholweni. Xa umahluko wendlela yesandi phakathi kwesandi esithe ngqo kunye nesandi esibonakalisiweyo sifikelela kwi-17m, umahluko wexesha phakathi kwezandi ezimbini ufikelela kuma-50ms, kwaye indlebe yomntu inokuva i-echo. Kwezinye iiholo ezinde, isandi esiphuma kudonga olungasemva sinokuvakala kwindawo yokuhlala ekufutshane nesango leqonga. Inokupheliswa ngokucwangcisa izixhobo zebhodi ezomeleleyo ezifunxa isandi kudonga olungasemva. Umzekelo, udonga olungasemva olune-arc kunye nophahla olunophahla lwesakhiwo luya kuzisa ingqalelo kwiholo. Ukuba ufuna ukugcina imilo ye-trapezoid yasekuqaleni kwigumbi, ungasebenzisa indlela yokucwangcisa izinto ezinamandla ezithatha isandi kule ndawo yangaphakathi ukuphelisa ukugxila kwiholo.
(4) Ukuphucula ukugquma kwesandi sokukhanya kunye neendonga zebhodi ezincinci. Okufana nebhodi yegypsum, ibhodi ye-silicon-calcium, ibhodi ye-FC, ibhodi ye-TK kunye nebhodi yesamente ye-magnesium engenamlilo kunye nezinye iindonga zebhodi ezikhanyayo kunye nezincinci. Ukuzalisa i-interlayer kunye nezixhobo ezixhamlayo ezithatha isandi ezifana noboya beglasi, uboya belitye kunye noboya bamaminerali kunokuphucula kakhulu impembelelo yomsindo wolu hlobo lodonga lwebhodi.
