Qhov zoo ntawm kev xav nyob rau hauv kev tsim cia txias cia khoom khoob
Thaum tsim kom muaj qhov txias txias cia khoom, peb xub thawj yuav tsum paub qhov txawv cov chav txias. Nyob rau hauv high txias txias cia, qhov kub thiab txias yuav tsum tswj ntawm 0 ℃ ~ 6 ℃ .Yog muaj ntau hom khoom cia: zaub, txiv hmab txiv ntoo, cov mis tshiab, thiab cov nqaij txias. Nyob rau hauv qis txias cia txias, qhov kub qhov xav tau kev tswj ntawm -18 ℃ ~ -20 ℃. Muaj ntau hom khoom cia: khov nqaij, khov pastry, ice cream thiab khov pob txha. Hauv qhov tseeb, -18 ℃ txias chav no yog sib xws.
1. Xaiv cov khoom siv racking steel
Qhov kub tsis muaj kub muaj qhov yuav tsum tau muaj rau daim ntawv thov hlau. Nws yuav tsum tau muaj kev kub taub hau tsawg thiab muaj zog kom tsis txhob txhav tawg. Feem ntau siv rau hauv kev sib tw ntawm cov pa roj carbon monoxide q2 Q235, muaj Q235A, Q235B, Q235C, Q235D, Q235E qib sib txawv, feem ntau yog vim muaj kev kub ntxhov. Ib qho txhais tau tias tsis muaj kev cuam tshuam, B yog siab tshaj 20 ℃, C yog siab tshaj 0 ℃, D yog saum toj no-20 ℃, E muaj tshaj -40 ℃, E mus txawv txawv, thiab lawv cov khoom sib txawv nyias txawv nyias.
Vim lub microelement sib txawv hauv A / B / C / D, qib zoo dua yog nce siab dua, thiab nws cov kev ua haujlwm hauv qis tsis zoo dua. Feem ntau, Q235D yuav raug siv los ua cov khoom tseem ceeb ntawm kev cia txias cia khoom.
Fasteners yog fabricated los ntawm high nickel chromium (xws li, Cr18Ni9), hlau hlau, lossis hlau tsis yog hlau (xws li tooj liab thiab txhuas), uas ua rau pom tsis muaj qhov ntsuas kub tsawg. Lub thermal expansion coefficient ntawm cov hlau yog 1.2 * 10 -5 / ℃. Lub thermal expansion coefficient ntawm cov pob zeb yog li 0.7 * 10 -5 / ℃. Ob ntawm lawv yog cov nyob ze thiab muaj peev xwm ua tau zoo txuas thaum kub qhov sib txawv yog li ntawm 40 ℃.
