Ukuthetha ngesithintelo sesandi, wonke umntu kufuneka aqhelane nayo.Njengomlindi wendlela, yakhiwe kumthombo wengxolo okanye kumacala omabini endlela.Xa ingxolo idluliselwa kwisithintelo sesandi, iya kubethelwa kwaye iya kubamba inxalenye.Emva koko umqobo wesandi usekelwe ikakhulu kwisiphi isandi sokufunxa.Intoni?Namhlanje, abavelisi bokuthintela isandi baya kukuxelela malunga nayo.
Umenzi wesithintelo sesandi
1. Uboya beglasi
Uboya beglasi obusecentrifugal luhlobo lwemathiriyeli yokugquma i-thermal eyavela ngeminyaka yoo-1980.Lilungu losapho lwefibre yeglasi.Isebenzisa itekhnoloji yokuvuthela ye-centrifugal yezizwe ngezizwe ukufeyitha iglasi etyhidiweyo kwaye itshizwe ngentlaka ye-thermosetting.Izinto ke zinyangwa nge-thermal.
Uboya beglasi ubukhulu becala benziwe ngesanti yequartz, i-feldspar, i-sodium silicate, i-boric acid, njl.njl., Ezenziwe ngobushushu obuphezulu beglasi enyibilikayo yomqhaphu wefiber.
Iimpawu zemveliso yeglasi yekotoni efunxa isandi: ubunzima obulula, i-coefficient yokufunxa isandi esiphakamileyo, ukusebenza kakuhle kwedangatye kunye nokuzinza okuhle kweekhemikhali, kwaye bubungqina bokufuma.
2. I-Aluminiyam ifayibha
Iphaneli ye-aluminiyam ye-aluminiyam efunxa isandi luhlobo lwesinyithi olufunxa isandi esenziwe yi-aluminiyam enamacala amabini anemingxuma edibanisa i-sandwiching ye-aluminiyam yefiber kunye nefoyile ye-aluminiyam.Inomsebenzi ogqwesileyo wokufunxa isandi, ukomelela okuphezulu, izinto ezilula, uthutho olufanelekileyo kunye nokumelana nemozulu elungileyo.
I-aluminium fiber inezi mpawu zilandelayo:
Izinto eziphathekayo ezi-Ultra-thin: Ubukhulu bepaneli ye-aluminium i-fiber sound absorbing panel ngokubanzi phakathi kwe-0.8-2mm, kwaye ubuninzi bomgangatho webhodi yi-1.4-3.2kg / m2.Kulula ukuthutha ngenxa yobukhulu bayo obuncinci kunye nobunzima obulula
1. I-coefficient yokunciphisa ingxolo eyi-35mm engqindilili yi-0.7, kunye ne-1.8mm engqindilili yokunciphisa ingxolo yi-0.9.
Ukuhlobisa: Ibhodi inokupeyintwa ngemibala eyahlukeneyo, umbala mhle kakhulu, unempembelelo yokuhlobisa kunye nokufunxa isandi.
Ukucutshungulwa ngokufanelekileyo: Ipleyiti ye-aluminium inokucutshungulwa kakuhle kakhulu, kulula ukuyibhola, ukugoba kunye nokusika.Xa ulwakhiwo luqhutywa, akusayi kubakho luthuli lwefiber lusasaza kwaye lungcolise imo engqongileyo kwaye luchaphazela impilo yabasebenzi.
2, i-aluminiyam yogwebu
I-aluminiyam i-foam yenziwe nge-aluminiyam ecocekileyo okanye yongezwe kunye nezongezo kwi-aluminium alloy.Inamagwebu kwaye ineempawu zentsimbi kunye nogwebu.
Ipleyiti ye-aluminium ye-foam inomsebenzi omhle kakhulu wokufunxa isandi, i-coefficient ye-avareji yokufunxa isandi ayikho ngaphezu kwe-0.64, kwaye i-coefficient yokunciphisa ingxolo iphakathi kwe-NRCO.75, elunge kakhulu kwingxolo yendlela ehamba phambili esekelwe kwi-frequency ephakathi kunye nephantsi. , kwaye yongamile kunezinye iintlobo zemathiriyeli efunxa isandi.Umphezulu we-aluminium enogwebu unokuzicoca ngokwawo emva kwemvula, ngaphandle kokuchaphazela ukusebenza kwe-acoustic.
