Ua tib zoo saib cov ntaub ntawv. Aluminium profiles, tuab, lub zog thiab oxide zaj duab xis siv rau siab {{0}} zoo aluminium alloy qhov rooj thiab qhov rais yuav tsum ua raws li cov qauv hauv lub tebchaws. Phab ntsa tuab yuav tsum siab tshaj 2.0 hli, lub zog tensile yuav tsum ncav cuag 157 Newtons ib square millimeter, lub zog tawm los yuav tsum ncav cuag 108 Newtons ib square millimeter, thiab oxide zaj duab xis thickness yuav tsum ncav cuag 10 microns. Yog tias tsis tau raws li cov qauv saum toj no, aluminium alloy qhov rooj thiab qhov rais yog qhov tsis zoo thiab siv tsis tau.
Qhov thib ob, saib kev ua haujlwm. High- zoo aluminium alloy qhov rooj thiab qhov rais, kev ua haujlwm zoo, kev teeb tsa zoo, kev sib khi zoo, thiab qhib thiab kaw tau yooj yim. Inferior aluminium alloy qhov rooj thiab qhov rais, blindly xaiv cov series thiab specifications ntawm txhuas profiles, ntxhib ua, siv txiav txiav es tsis txhob milling, tsis txhob nruab raws li yuav tsum tau, tsis zoo sealing kev ua tau zoo, tsis yooj yim hloov, tsis tsuas yog huab cua to thiab nag thiab iav tawg, tab sis kuj nyob rau hauv cov cua muaj zog thiab sab nraud quab yuam, nws yog ib qho yooj yim rau khawb los yog khob qhov rooj zawv zawg qhov rooj los yog iav, ua rau neeg puas tsuaj.
Peb saib ntawm tus nqi. Feem ntau, tus nqi siab {{0}}} zoo aluminium alloy qhov rooj thiab qhov rais yog li 30 feem pua siab dua li qhov tsis zoo ntawm aluminium alloy qhov rooj thiab qhov rais vim cov nqi ntau lawm. Qee qhov aluminium alloy qhov rooj thiab qhov rais ua los ntawm txhuas profile nrog phab ntsa tuab ntawm tsuas yog 0.6-0.8 hli, lub zog tensile thiab lub zog tawm los yog qis dua li cov qauv hauv lub tebchaws, thiab nws tsis zoo siv heev. Tsis tas li ntawd, muaj ntau tus neeg ua haujlwm tus kheej ua cov txheej txheem aluminium alloy qhov rooj thiab qhov rais, thiab lawv tsis nkag siab txog cov yam ntxwv ntawm cov qauv thiab kev ua haujlwm ntawm aluminium alloy qhov rooj thiab qhov rais. Txhawm rau txo cov nqi thiab txiav cov ces kaum, siv cov khoom tsis zoo, thiab cov khoom siv zais cia yog qhov loj, yog li nws feem ntau tsis tsim nyog siv. Nws yog qhov zoo tshaj plaws los xaiv cov khoom lag luam los ntawm cov khoom siv aluminium alloy qhov rooj thiab qhov rais manufacturers. Nov yog qhov tshwj xeeb: lub teb chaws tus qauv profile thickness yog 1.4mm. Yog tias tus neeg muag khoom xaiv cov khoom siv nrog phab ntsa tuab ntawm 1.2mm lossis 1.0mm lossis txawm tias nyias, nws yog cov khoom tsis ua raws li tus qauv. Thov xyuam xim thaum yuav khoom.
Plaub saib ntawm cov khoom
Muaj 6 yam tseem ceeb rau kev siv hauv cov ntaub ntawv:
⒈Thickness: There are 70 series and 90 series of aluminum alloy sliding doors and windows, and 70 series can be used for aluminum alloy sliding doors inside the house. The aluminum alloy series number indicates the thickness of the door frame in millimeters of the structural dimension. Common aluminum alloy sliding windows include 55 series, 60 series, 70 series and 90 series. The selection should be determined according to the size of the window hole and the local wind pressure value. The aluminum alloy sliding window used as a closed balcony should not be less than 70 series.
⒉ Strength: The tensile strength should reach 157 Newtons per square millimeter, and the yield strength should reach 108 Newtons per square millimeter. When purchasing, the profile can be bent moderately, and it should be able to return to its original shape after letting go.
3. Chromaticity: tib aluminium alloy profile yuav tsum muaj tib xim thiab luster. Yog tias qhov sib txawv xim yog pom tseeb, nws tsis haum rau kev yuav khoom.
⒋ Flatness: Check the surface of the aluminum alloy profile, there should be no dents or bulges.
⒌Gloss: Aluminum alloy doors and windows should avoid buying profiles with obvious defects such as open bubbles (white spots) and slag (black spots), cracks, burrs, and peeling on the surface.
⒍Oxidation degree: The thickness of the oxide film should reach 10 microns. When purchasing, swipe lightly on the surface of the profile to see if the oxide film on the surface can be wiped off.
