Ipayipi Le-Foam Le-Phenolic | Ipayipi Elingashisi Elingashiswa Ngaphambili Le-HVAC, Ukuvikelwa Komlilo kanye Nokugcina Okubandayo
1. Ukubuka Konke Komkhiqizo
Ipayipi le-foam le-phenolic, elaziwa kakhulu ngokuthi igobolondo lepayipi le-phenolic, liyi-GB 8624 Grade A engashisi. Le payipi ye-thermosetting eqinile, eyenziwe nge-foam ehlanganisiwe ye-resin ye-phenolic eguquliwe, iyatholakala nge-aluminium foil noma i-fiberglass surface finishes. Inentuthu ephansi, ayinabo ubuthi kanye nezakhiwo ezigcwele ze-hydrophobic, ihlanganiswe nokuzinza okubanzi kakhulu, isebenza njengesixazululo sepayipi esisezingeni eliphezulu esifakwe i-insulation sezinhlelo ze-HVAC, amapayipi okuvikela umlilo, izindawo zokugcina ezibandayo kanye namaphrojekthi ahlukahlukene okufaka amapayipi ezimbonini asezingeni eliphansi.
2. Izinhlobo Zomkhiqizo Nemininingwane
Lo mkhiqizo uyigobolondo lepayipi eliqinile elibunjwe ngokuphelele, elihlinzekwa ngezinhlobo ezizinamathelayo nezivikelayo ebusweni. Ivumela ukugoqwa okulula nokufakwa ngokuqinile kwamapayipi ayindilinga, okuhambisana nezidingo ezahlukahlukene zokufakwa endaweni.
Ubuso Bobuso: Ibhodi elilula, i-foil ye-aluminium eyodwa/ezinhlangothini ezimbili, i-foil ye-aluminium eqinisiwe, indwangu ye-fiberglass
Ububanzi bepayipi: DN15～DN600 isitokwe, ukukhiqizwa kwesikhunta okwenziwe ngokwezifiso kosayizi abangewona abajwayelekile
Ubukhulu bokushisisa: 15/20/25/30/40/50mm, ubukhulu obungenziwa ngezifiso kusukela ku-20mm kuya ku-100mm
Ubude Obujwayelekile: 1000mm ngengxenye ngayinye, insizakalo yokusika ngokwezifiso iyatholakala
3. Izici Zomkhiqizo Eziyinhloko
Ukuphepha Komlilo Okungashisi Futhi Okuthembekile Kwebanga A
Ihambisana nezindinganiso ze-GB 8624 Grade A ezingashi. Izinto ziphenduka zibe yi-carbon kuphela uma zichayeka elangeni, ngaphandle kokuvuza okuncibilikisiwe, ukusabalala kwamalangabi, intuthu eningi noma ukukhishwa okunobuthi. Ifinyelela isilinganiso sobuningi bentuthu esingu-SDR ≤75, ihlinzeka ngokusebenza okuphansi kwentuthu kanye nokungabi nobuthi ngesikhathi sezehlakalo zomlilo. Kuyindlela ephephile efanelekile esikhundleni samapayipi okushisa e-PU kanye ne-polystyrene avuthayo kumaphrojekthi anezidingo eziqinile zokuvikela umlilo.
Ukushisa Okuphansi Kakhulu Nokusebenza Kahle Kakhulu Kwamandla
Ihlolwe ngokwezindinganiso ze-GB/T 10294, ukuhanjiswa kokushisa kungu-≤0.030 W/(m·K) @ 25℃. Isakhiwo sayo esiqinile samaseli avaliwe sinciphisa ngempumelelo ukudluliselwa kokubanda nokushisa ezindaweni zamapayipi, sihlinzeka ngokufakwa kokushisa okuqhubekayo kanye nokusebenza okonga amandla isikhathi eside kwezinhlelo zamapayipi ezakhiweni nasezimbonini.
Ukuzivumelanisa Nezimo Zokushisa Ezibanzi Kakhulu
Isekela ukusebenza okuzinzile okuqhubekayo ngaphakathi kwebanga lokushisa eliphakathi kuka -196℃ kuya ku- +200℃. Isakhiwo se-thermosetting esiqinile simelana nokuqhekeka okubuthakathaka ngaphansi kwezimo eziphansi kakhulu ze-cryogenic futhi sivimbela ukuguquguquka kokushisa emazingeni okushisa aphakathi, okulungele kokubili ukugcinwa kokuqandisa okujulile kanye nezimo zokuvimbela ukushisa ezivamile.
Ukusebenza Okuphezulu Kokungazinzi Kwamaseli Avaliwe kanye Nokulwa Nokufiphaza
Ngesilinganiso samaseli avaliwe ≥90% (GB/T 10799), izinga lokungangenisi amanzi ≥98% (GB/T 10299) kanye nomthamo wokumuncwa kwamanzi olawulwa ngaphansi kuka-3%, umkhiqizo ubonisa ukusebenza okuphezulu kokungabi namanzi. Uvimba ngempumelelo ukungena komswakama, uvimbela ukukhula kwesikhunta futhi uqede ukuminyana kwamapayipi, ugcina ukusebenza okuzinzile kokuvikela ezindaweni zokusebenza ezinomswakama isikhathi eside.
Ukuzinza Okuphezulu Kobukhulu
Isakhiwo sama-molecule e-thermosetting siqinisekisa izakhiwo zomzimba ezizinzile ngaphansi kwamazinga okushisa ashintshashintshayo. Ngemva kokuguga okungaguquki kwamahora angu-48 ku-70℃, izinga lokushintsha kobukhulu lihlala lingu-≤1%. Limelana ngempumelelo nokuqhekeka, ukuhlukanisa kanye nokugoba, liqinisekisa ukulingana okuhlala njalo kanye nesakhiwo sokuvikela esingaguquki kumapayipi.
Ifomula engena-formaldehyde kanye nempilo yesevisi ende
Njengoba ingenayo i-formaldehyde, i-fluorine kanye nezinto eziyingozi ezishintshashintshayo, le phayiphu yokuvikela ihlanzekile, inobungani nemvelo futhi ihambisana ngokugcwele nezindinganiso zokwakha amakamelo angaphakathi nahlanzekile. Ine-asidi enhle kakhulu, i-alkali kanye nokumelana nokuguga, inikeza impilo yenkonzo engaphezu kweminyaka engama-20 ngaphansi kwezimo zokufakwa ezijwayelekile kanye nokusebenza.
Isakhiwo Esinezimbobo Ezincane Sokunciphisa Umsindo Okuphumelelayo
Isakhiwo sangaphakathi esiyingqayizivele esinezimbobo ezincane sifinyelela i-coefficient yokunciphisa umsindo engu-NRC ≥0.7 ngokwezinga lokuhlola le-ASTM C423. Simunca kahle umsindo wokungqubuzana komoya kanye nomsindo wokudlidliza komshini, sithuthukisa kakhulu ukuthula kokusebenza kwezinhlelo ze-HVAC kanye nezamapayipi ezimboni.
