Daim duab hauv qab no sib piv cov khoom siv lub cev ntawm cov hlau siv hauv lub ru tsev. Nws yog ib qho tseem ceeb kom paub qhov txawv ntawm cov hlau thiab lawv cov khoom raws li lub hom phiaj sib dhos thiab siv. Nrog rau cov hlau, ib qho teeb meem tshwj xeeb yog lawv qhov yooj yim vim yog cua sov nthuav dav. Copper yog 1.4 npaug ntawm qhov hloov pauv ntau dua li hlau, ua rau nws ntau dua lossis tsawg dua ib yam li cov hlau tsis muaj steel, thiab yog 70% hloov pauv raws li txhuas. Nyob rau hauv qhov siab ntawm lub caij ntuj sov qhov kub ntawm cov nplooj ntawv tooj liab nce mus txog 80 degree ua qhov sib txawv ntawm 90-100 degree nrog nws lub caij ntuj no kub. Lub tshav kub expansion raws li qhov kub thiab txias sib txawv yog 100 x 1.7=170mm. Piv txwv li, ib leeg batten seam ntawm 100m yuav nthuav thiab cog lus los ntawm 170mm. Qhov ntev tshaj plaws ntawm cov tooj liab plating yog tsau ntawm 6m thiab nruab nrab ntawm 5-6m nthuav dav yog coj mus rau qhov sib txawv me me rau tiling.
Raws li Young's modulus, uas yog tus qauv rau kev ncab thiab khoov, tooj liab tuaj ntawm 60% ntawm cov hlau lead ua rau nws cov hlau zoo nkauj. Thaum qhov no ua rau nws yooj yim rau kev ua haujlwm, nws kuj ua rau kev hloov pauv ntawm nws cov duab vim kev nthuav dav thiab kev cog lus thiab kev quab yuam sab nraud. Nws yog 3/4 nyuaj li hlau thiab ib nrab nyuaj li stainless nyiag lub ntsiab lus ntawm qhov chaw tuaj yeem raug puas tsuaj thaum lub sij hawm sib dhos - yuav tsum tau saib xyuas thaum ua haujlwm ntawm cov hlau.
