Chitoliro chachikhalidwe cha mpweya chapakati cha mpweya wapakati nthawi zambiri chimapangidwa ndi chitsulo kapena galasi CHIKWANGWANI cholimbitsa pulasitiki chamkati, chokulungidwa ndi zipangizo zotenthetsera kutentha, ndikukulungidwa ndi zojambulazo za aluminiyamu pamtunda wakunja, zomwe zimapangitsa kuti chitoliro cha mpweya chikhale cholemera kwambiri. , ntchito ndi nthawi yomanga ndi kuika, kusawoneka bwino, kuchepa kwa mpweya komanso kugwiritsa ntchito mphamvu zambiri.Poyerekeza ndi ma ducts am'mlengalenga, ma phenolic composite air ducts ali ndi izi:
1. Kutsekemera kwabwino kwa kutentha, komwe kungachepetse kwambiri kutentha kwa mpweya
The matenthedwe madutsidwe wa phenolic gulu mpweya duct ndi 0.016 ~ 0.036w / (m · K), pamene matenthedwe madutsidwe wa kanasonkhezereka zitsulo duct ndi FRP duct ndi lalikulu kwambiri.Kuphatikiza apo, njira yapadera yolumikizirana ndi phenolic composite air duct imatsimikizira kulimba kwa mpweya wabwino kwambiri wa mpweya wabwino, womwe uli pafupi ndi nthawi 8 za chitsulo chachitsulo.Deta ina ikuwonetsa kuti kutentha komweko (kuzizira) kumafalikira, kutayika kwa kutentha kwa chitoliro chachitsulo ndi 15%, kutayika kwa kutentha kwa chitoliro cha FRP ndi 8%, ndi kutaya kwa kutentha kwa mpweya wa phenolic thovu. chitoliro ndi osachepera 2%.
2. Kukhala chete kwabwino.
The interlayer phenolic aluminiyamu zojambulazo kompositi mpweya ngalande khoma ndi perforated phenolic thovu zinthu mbale, amene ali ndi ntchito yabwino kuthetsa phokoso.Pakatikati pa mpweya wa mpweya, phokoso lopangidwa ndi mpweya woyatsira mpweya panthawi yogwira ntchito liri mumtundu wa 50-79db, womwe umafalitsidwa kudzera mu chitoliro cha mpweya kuti apange phokoso lamkati.Phenolic aluminiyamu zojambulazo zopangidwa ndi mpweya duct palokha ndi wabwino kwambiri chitoliro muffler, ndipo palibe chifukwa chokhazika chala zipangizo monga chete chivundikiro ndi mwakachetechete chigongono.
3. Kulemera kwapang'onopang'ono, kungathe kuchepetsa katundu wa nyumba, ndikuyika mosavuta
Kulemera kwa phenolic aluminiyamu zojambulazo gulu mpweya ngalande ndi kuwala, pafupifupi 1.4 makilogalamu / m2, pamene voliyumu kulemera kanasonkhezereka zitsulo pepala mpweya ngalande (0.8 mm wandiweyani) ndi FRP mpweya ngalande (3 mm wandiweyani) ndi 7.08 makilogalamu / m2 ndi 15 ~ 20 kg / m2 motsatana, zomwe zingachepetse kwambiri katundu wa nyumbayo ndipo ndizopindulitsa kwambiri pakuyika njira ya mpweya.Pakuyika, chithandizo chimodzi chokha chimafunikira ma 4m aliwonse kapena kupitilira apo kuti mukhale ndi mphamvu zokwanira zothandizira.Izi zimachepetsa kwambiri mphamvu zonyamula katundu zothandizira ndi zopachika, zomwe zimapangitsa kuti mayendedwe ndi unsembe zikhale zosavuta.
4. Moyo wokhalitsa komanso wautali wautumiki
Mbale yachitsulo yamalata ndiyosavuta kudzimbirira m'malo onyowa, pomwe pulasitiki yolimba yagalasi ndiyosavuta kukalamba komanso kuwonongeka.Choncho, moyo utumiki wa ducts chikhalidwe mpweya si yaitali, pafupifupi 5-10 zaka.Moyo wautumiki wa wosanjikiza wotsekera wokulungidwa ndi ma ducts ampweya, monga ubweya wagalasi, ndi zaka 5 zokha, pomwe moyo wautumiki wa ma phenolic aluminium zojambulazo zopangira mpweya ndi zaka zosachepera 20.Choncho, moyo wautumiki wa phenolic aluminium zojambulazo zopangira mpweya wophatikizika ndi nthawi yoposa katatu kuposa njira yachikhalidwe ya mpweya.Kuphatikiza apo, kugwiritsanso ntchito kaphatikizidwe ka phenolic aluminium zojambulazo kumatha kufika 60% ~ 80%, pomwe njira yachikhalidwe yopangira mpweya siyingagwiritsidwenso ntchito.
5. Chepetsani kutalika kwa pansi
Njira yachikhalidwe yopangira mpweya imafunikira kuti pakhale malo osungiramo zotchingira pamalopo, chifukwa chake pamafunika kutalika kwina komanga, komwe kumapereka zofunika zina za kutalika kwa nyumbayo.Phenolic aluminiyamu zojambulazo kompositi mpweya ngalande safuna pa malo kutchinjiriza kumanga, kotero sikoyenera kusunga malo omanga, amene angathe kuchepetsa pansi kutalika kwa nyumbayo.
