Nk’ibikoresho byo gukingira inyubako mu buryo bworoshye kandi bukoresha ingufu nyinshi, ipantalo ya polyurethane sandwich yabaye igice cy’ingenzi cy’inganda zigezweho, ububiko bw’ibikoresho, n’ububiko bukonje. Ubwo bwoko bw’ipantalo y’inyubako, buhuza imiterere y’icyuma n’ibikoresho bya polyurethane, byitezwe ko buzaba ingenzi cyane mu gihe kizaza.
Imikorere myiza cyane
Akamaro k'ingenzi k'urukuta rwa polyurethane sandwich ni uko rufite ubushobozi bwo gukingira ubushyuhe butangaje. Ibikoresho bya polyurethane foam bifite ubushobozi bwo gukingira ubushyuhe, bifite ubushobozi bwo gutwara ubushyuhe buri hagati ya 0.017-0.025 W/(m·K). Ibi bivuze ko urukuta rufite ubugari bwa santimetero 5 gusa rushobora kugira ubushobozi bwo gukingira ubushyuhe nk'ubw'urukuta rwa sima rufite ubugari bwa metero imwe. Kubera ubushobozi bwarwo bwiza bwo gukingira ubushyuhe, urukuta rwa polyurethane sandwich rwabaye ibikoresho bikunzwe cyane mu kubaka ahantu hakonje ho kubika ibintu.
Gukingira amazi, kudahura n'ubushuhe, no kudahungabana cyane ni inyungu z'inyongera ku mapaneli ya polyurethane sandwich. Igipimo cy'uturemangingo dufunze cy'imbere ya polyurethane foam kirenga 95%, bibuza amazi kwinjira. Igipimo cy'amazi ku mapaneli ya polyurethane sandwich kiri munsi ya 3%. Muri icyo gihe, iyo ubushyuhe bwa 30°C buhindutse, impinduka mu ngero z'amapaneli ziri munsi ya 1%, bigatuma akoreshwa igihe kirekire nta guhindagurika.
Ubushobozi bwo kurwanya umuriro bw'amasashe ya polyurethane bushobora kugera ku cyiciro cya B1. Amasashe ya polyurethane arashya, ariko ahagarara gushya amasegonda 3 gusa nyuma yo gukurwa mu muriro. Nubwo ari make gato ugereranije n'amasashe ya sandwich y'ubwoya bw'amabuye muri urwo rwego, aracyakurikiza ibisabwa by'ibanze mu kwirinda inkongi.
Mu miterere, bitewe n'imiterere ibiri y'ibyuma hejuru no hasi, ibyuma bya polyurethane bifite imbaraga nziza mu miterere. Imbaraga zo gukanda za polyurethane sandwich panels zirenga 150 kPa. Ariko, ibikoresho by'ingenzi ni polyurethane foam, bituma ibyuma byoroshye 30-60% ugereranyije n'ibicuruzwa gakondo. Ibi bituma ibyuma bya polyurethane sandwich panels biba ibikoresho bikunzwe cyane mu bwubatsi bworoshye.
Ubusabe bwinshi mu musaruro
Muri iki gihe, inzira yo gukora amapaneri ya polyurethane sandwich ikora cyane mu buryo bwikora. Inganda zikomeye, nka Harbin Dong'an Building Sheets Co., Ltd., zikoresha imirongo ihoraho yo gukora kugira ngo zihuze inzira yose yo gusuka ifuro, gukosora no kubumba amapaneri.
Gutera ifuro no kuyishyiraho hakoreshejwe umuvuduko mwinshi ni intambwe y'ingenzi mu gukora ifuro rya polyurethane. Ubwiza bw'ifuro bugena mu buryo butaziguye imikorere y'ifuro. Mu gihe cyo gukora, abakora ifuro bagomba kugenzura neza ubushyuhe bw'ikibaho cy'urunigi n'ibikoresho bitera ifuro. Umuvuduko w'umurongo w'umusaruro nawo ni ingenzi, kuko bigira ingaruka ku buryo bungana mu gukora ifuro ry'ibanze.
