Ibhodi Le-Phenolic Foam – Ibanga A Lokufudumeza Okungashisi Kwe-HVAC, Isithiyo Somlilo Wesakhiwo kanye Nokugcina Izinto Ezibandayo
1. Ukubuka konke komkhiqizo
I-foam ye-phenolic iyi-foam eqinile ye-thermosetting yamaseli avaliwe ekhiqizwa ngezinto zokusetshenziswa ze-phenolic resin. Ithola isitifiketi se-Grade A esingashi ngokuhambisana nezindinganiso zokuhlolwa komlilo ze-GB 8624. Inamandla okumelana nomlilo okuvelele, ukuhanjiswa kokushisa okuphansi, ukubekezelela amazinga okushisa okubanzi kanye nezici zokungangeni manzi nokulwa nokuguga, le nto yokuvikela isetshenziswa kabanzi ezindongeni zesakhiwo, imichilo yokuhlukanisa umlilo, ulwelwesi lwamapayipi omoya, izindawo zokugcina ezibandayo kanye nokufakwa kokushisa kwegumbi lokuhlanza kumaphrojekthi okwakha asezingeni eliphezulu.
2. Izinhlobo Zomkhiqizo Nemininingwane
Sakha izinhlobo eziningi eziqediwe ezihambisana nezimo zesayithi ezihlukile: ibhodi elingenalutho elingenalutho, iphaneli ye-phenolic ebheke nge-aluminium foil eyodwa noma ezimbili, ibhodi ye-phenolic ehlanganisiwe yensimbi enombala kanye nebhodi ye-phenolic embozwe ngendwangu ye-fiberglass. Ubukhulu obujwayelekile: 15/20/25/30/40/50mm, ubukhulu obenziwe ngokwezifiso obusukela ku-20mm kuya ku-100mm uma kuceliwe Ubukhulu obujwayelekile: 1200×3000mm, 1000×2000mm, ukusika okwenziwe ngokwezifiso kwasefekthri kanye nosayizi ongajwayelekile kuyamukeleka.
3. Izici Zomkhiqizo Eziyinhloko
Ibanga A alishi futhi lihambisana ngokugcwele namakhodi omlilo
Isilinganiso se-A esingashi ngaphansi kwezidingo zokuhlolwa ze-GB 8624. Uma sibekwe elangeni elivulekile, iphaneli iphenduka i-carbon kuphela ngaphandle kokusha okuqhubekayo, ukwakheka kokuwa okuncibilikisiwe, intuthu eningi noma ukukhishwa kwegesi enobuthi futhi ivimbele ukusabalala komlilo ngempumelelo. Isebenza njengendlela ephephile esikhundleni se-EPS evuthayo, i-XPS kanye ne-PU yokuvikela emisebenzini yokwakha ebalulekile emlilweni.
Ukushisa Okuphansi Kakhulu Ukuze Kuncishiswe Ukulahlekelwa Amandla Kwesikhathi Eside
Ukushisa kuhlala ngaphansi kuka-0.030 W/(m·K) @ 25℃. Ukwakheka kwamaseli avaliwe amancane kunikeza ukuvimba okuthembekile kokushisa, kunciphisa ukubanda nokuvuza kokushisa ukuze kugcinwe imiphumela eqhubekayo yokonga amandla unyaka wonke.
Ukuzivumelanisa Nezimo Zokushisa Ezibanzi Zezimo Zokusebenza Ezihlukahlukene
Igcina isevisi ezinzile yesikhathi eside phakathi kuka -196℃ no +200℃. Akukho ukuncishiswa kokushisa ngaphansi kokushisa okuphezulu noma ukuqhekeka ngaphansi kokushisa okuphansi kakhulu, kufaka kokubili ukugcinwa kokubanda okubandayo kanye nezakhiwo zokushisa ezisezingeni eliphakathi nendawo.
Ukwakheka kwe-Hydrophobic Hydro-Cell okuvaliwe kuvimbela umswakama kanye nokuminyana
Isilinganiso samaseli avaliwe sifinyelela ngaphezu kuka-90%, izinga lokuxosha amanzi ≥98% lapho ukumuncwa kwamanzi ngobuningi kulawulwa ngaphakathi kuka-3%. Impahla enjalo ebonakalayo ivimba ukungena okumanzi nokukhula kwesikhunta, igwema ukuminyana okuphindaphindiwe emigudwini yomoya nasezindongeni ezindaweni ezinomswakama.
Ukuzinza Okuphezulu Kokumelana Nokuguquka
Isakhiwo sama-molecule se-thermosetting sinikeza ukuzinza okuqinile kwesakhiwo. Ukwehluka kwaso ngobukhulu kuhlala kungaphansi kuka-1% ngemva kokuguga kwamahora angu-48 ku-70℃, kumelana nokugoqwa, ukuqhekeka kanye nokuhlukaniswa kwezingqimba phakathi kokushintsha kwezinga lokushisa okuvamile ukuze kuqinisekiswe ukusebenza kahle kokuvikela okuhlala isikhathi eside.
Ifomula ye-Zero Formaldehyde Eco ene-Extended Service Life
Ayinazo izithasiselo ze-formaldehyde ne-fluorocarbon ngaphandle kokukhishwa kwezinto eziyingozi ezishintshashintshayo, iphephile ngokwanele ukufakwa ngaphakathi nasendlini yokuhlanza. Amandla amahle okulwa nokuguga nokulwa nokugqwala enza kube nokwenzeka iminyaka engaphezu kwengu-20 yokusebenza ngaphansi kwezimo zokusebenza ezijwayelekile.
Isakhiwo Esinezimbobo Siletha Ukumuncwa Komsindo Okuphumelelayo
Ukwakheka kwe-intrinsic microporous kufinyelela ku-NRC ≥0.7 okulinganiswe nge-ASTM C423 ngayinye, okumunca umsindo womoya wokungenisa umoya kanye nokudlidliza komshini ukuze kufezwe ukunciphisa umsindo osizayo kwezakhiwo namakamelo emishini.
