Ni iki kigira ingaruka ku giciro cya paneli ya pur?

Puf panel ikoreshwa cyane mu bwubatsi, mu bubiko bukonjesha, mu nyubako z'inganda, no mu nyubako za modular, bitewe n'imikorere yazo yo hejuru yo gukingira no kwihuta mu gushyiraho. Nubwo abubatsi n'abubatsi baha agaciro imikorere yabo, ibiciro biratandukana cyane bitewe n'ibintu byinshi bishobora gupimwa.

Ubunini bw'urupapuro n'imikorere yarwo mu gukingira

Ubunini bw'imbere y'agasanduku k'imyenda ka PU bufitanye isano itaziguye n'igiciro cyako. Ubunini busanzwe buri hagati ya mm 40 na mm 250, aho agasanduku gafite ubunini butanga ubushyuhe bwiza (agaciro ka U gake) ariko gasaba ibikoresho fatizo byinshi.

Igikoresho cya Puf cya mm 100 gikunze kugura 20-30% birenga mm 50 bitewe n’ubwiyongere bw’ingano ya polyurethane foam hamwe n’agaciro ka R-value kazamutse, ibyo bikaba bishobora kugabanya cyane imitwaro yo gushyushya no gukonjesha mu gihe cyose inyubako ikora.

Gukoresha neza ubushyuhe bigira ingaruka ku giciro kuko kugera ku bushyuhe buke (hafi 0.022 W/m·K kuri PU) bisaba ifuro rikwiye no kugenzura ubuziranenge.

Ibikoresho by'ingenzi n'ubucucike

Polyurethane ubwayo igira uruhare runini mu ifaranga. Imiterere y’uturemangingo tw’ifuro rya PU ifunze neza itanga ubushyuhe bwiza ugereranije n’ubundi buryo nka EPS (polystyrene yagutse), ariko ibikoresho byayo fatizo—polyols na isocyanates—ni ibikomoka kuri peteroli kandi ibiciro bihindagurika. Amakuru y’inganda agaragaza ko ikiguzi cy’ibikoresho fatizo kigize 60–70% by’amafaranga yose akoreshwa mu gukora pan.

Byongeye kandi, ubucucike bw'ifuro bugira ingaruka ku mikorere n'igiciro. PU ifite ubucucike bwinshi itanga imbaraga nziza za mekanike kandi igatuma ubushyuhe budasaza neza ariko yongera ikiguzi bitewe n'uko ibikoresho bikoreshwa cyane no gutunganya ibintu bigoye. Puf panel ifite ubucucike bwinshi ishobora kugura 15-25% kurusha verisiyo zifite ubucucike buke.

Ibikoresho byo ku ruhande

Udupande twa Sandwich tugizwe n'inkingi ya PU ifatanye hagati y'ibyuma bibiri. Ibi bishobora kuba icyuma cya galvanized, icyuma cyasizwe irangi, cyangwa aluminiyumu. Bamwe mu bakora ibikoresho bikomeye, nka Harbin Dongan Building Sheets Company, batanga utwuma twa puf hamwe n'udupande twa Al-Mg-Mn, dushobora gutuma utwuma twa sandwich tworoha, turwanya ingese, kandi tugakomera.

Icyuma gikozwe mu mabati ni cyo gihendutse cyane kandi gitanga ubushobozi bwo kurwanya ingese, mu gihe icyuma gisizwe irangi rya PVDF cyangwa polyester cyongera ubwiza n'uburanga. Birumvikana ko byongera ikiguzi cyo gukora. Ibyuma bya aluminiyumu byoroshye kandi birwanya ingese ariko bizaba bihenze cyane kurusha icyuma.

Ubunini bw'uruhu rw'icyuma nabwo ni ingenzi. Muri rusange, ubunini bw'uruhu rw'icyuma ni 0.4-0.6 mm. Dongan Company ishobora gutanga ibipande bifite ubunini bw'uruhu rw'icyuma bwa 0.8 mm. Uruhu runini rutuma ibipande by'icyuma bikomera kandi bigatuma bikora neza, bivuze ko igiciro cyabyo kiri hejuru.

Ibipimo by'inkongi z'umuriro n'amahame y'umutekano

Imashini zisanzwe za Puf zikunze kugira amanota ari hagati y’inkongi z’umuriro nka Euro class E. Ariko, imishinga, kimwe n’inyubako za leta, amashuri, amavuriro, isaba umutekano wo hejuru. Imashini zihuye n’imikorere yo hejuru y’inkongi z’umuriro zisaba ibikoresho byihariye bigabanya inkongi z’umuriro cyangwa ibindi bikoresho, nka PIR, bigatuma umusaruro urushaho kuba mwinshi n’igiciro cyawo.

Ibikoresho byo gukora Sandwich Panels

Ibikoresho bikora bigira ingaruka zikomeye ku bwiza bw'ibice bya sandwich. Uburyo bugezweho kandi buhuriweho bushobora gutuma ibikoresho bya polyurethane bivamo ifuro rimwe ndetse n'uruvange rw'icyuma cy'ibikoresho by'ibanze.

Guhindura ibintu n'ibintu byihariye

Udupapuro dusanzwe twa PU turahendutse cyane bitewe n'uko dukorwa mu buryo bwikora. Ingano zihariye, imiterere yihariye, imiterere yihariye y'inkombe, cyangwa irangi rigezweho rya UV, ririnda gushonga, cyangwa irangi ry'inyubako byongera ikiguzi.

Urugero, uretse ibisanzwepaneli za sandwich, Dongan Company ishobora kandi gutanga amasahani yo gushushanyaho sandwich. Abakiriya bashobora guhitamo, cyangwa se bagahindura imiterere y'uruhu rw'icyuma bitewe n'ibyo bakunda n'imiterere y'inyubako. Gukora imiterere yihariye bivuze ko hagomba gukorwa ifumbire y'icyuma itandukanye, kandi ikiguzi cy'ifumbire kizagaragazwa n'igiciro cy'umusaruro urangiye.
