I-fiber ye-fiberKwindlela yokudluliselwa kobushushu kunokubahlulahlulwe kube yimilo eliqela, ukuhanjiswa kwe-radiation ye-pirous silo, i-moya engaphakathi kwi-fiber ye-fiber ye-fiber, apho ugqithiso lobushushu lwe-wirol lungahoywa. Ukuxinana kobushushu obukhulu kunye nobushushu bunolwalamano luxhomekeke kwi-Bulk, kubushushu obuphezulu, ukuthoba ubuninzi betyala, umlinganiselo we-radiation ubushushu bokudluliselwa kwe-radiation radiation. Kwiimveliso ze-fiber ye-fiber, ukuxinana kobuninzi kuhlala kungu-0.25g / cm ', isigaba esiqinileyo sinokubonwa njengokuqhubekayo, ke i-fiber eqinileyo yefibre incinci.
Ukuba nje kwithiyori yokuba ukuxinana kwabantu abaninzi kuyinto encinci, ukuqhubela phambili kwe-shirmal kuyinto enkulu, ububi obuxineneyo buyinto enkulu yokuqhutywa kwe-thermal incinci; Oku akuhambelani neyona meko, njengokhuquzelela ibhola ye-Slag yahlukile, nokuba umntu oxineneyo uyalingana, ukuze i-Porosity yevolumu yeCandelo ayifani, ke kuya kubakho umahluko kwi-ubukrokh ' Nangona kunjalo, izigqibo ezifanelekileyo zingashwankathelwa ngolu hlobo lulandelayo.
1. Ukuqhubela phambili kwe-shirmal yeI-fibers ye-RecrectoryIyancipha ngokunyuka kobugqi, kwaye ukwehla kokuncipha ngokuthe ngcembe, kodwa xa uxinzelelo lufikelela kuluhlu oluthile, ukungabikho komgangatho ongaphezulu kwe-shirmal akusancinane kwaye notyekelo lokunyuka ngokuthe ngcembe.
2. Kubushushu obahlukeneyo, kukho ubukhulu becala ukuqhutywa kwengqondo kunye nobuncinci obuhambelana nobuncinci. Ukuxinana ngokuhambelana nembonakalo esezantsi ye-hormal ye-surmal yonyuka ngokukhulisa ubushushu obukhulayo.
3. Ngobuninzi obunye, ukuqhubela phambili kwe-thermal kuyahluka ngobukhulu beepores.
(1) ubungakanani be-Pore 0.1mm.
I-0c ibe = 0.0244W / (m. K) I-100C xa λ = 0.0314w / (M)
(2) I-Aperture 2mm 2mm.
Kwi-0c = I-0.0314W / (M, k) λ = 0512w / (m) kwi-100c. K) kwi-100c. K)
Ububanzi be-pore ye-1mm, iqondo lobushushu liphuma ukusuka kwi-0c ukuya kwi-500c, ixabiso lokuqhubela phambili kwe-thermal lelo linyusa amaxesha ama-5.3; Ububanzi be-Pored ye-5mm, iqondo lobushushu liphuma ukusuka kwi-0c ukuya kwi-500c, ixabiso layo lokuphumelela linyukele izihlandlo ezili-11.7. Ke ngoko, inkulu le pores kwi-fiber ye-fiber, incinci yokuxinana ngokulinganayo, kwaye ukuqhubeka kwe-thermal kuyanda.
