7 Cov Qauv Ntsuas Kev Ntsuas Huab Cua Ua Haujlwm ntawm Cov Txheej Txheem Hmoov Txheej

Muaj 7 tus qauv los ntsuas huab cua tsis kam ntawm hmoov txheej.

• Kev tiv thaiv rau mortar
• Accelerated aging thiab UV durability (QUV)
• Saltspraytest
• Kesternich - kev xeem
• Florida-test
• Humiditytest (tropical kev nyab xeeb)
• Tshuaj tiv thaiv

Kev tiv thaiv rau mortar

Raws li tus qauv ASTM C207. Ib qho mortar tshwj xeeb yuav raug coj los sib cuag nrog cov hmoov txheej thaum 24h ntawm 23 ° C thiab 50% txheeb ze av noo.

Accelerated aging thiab UV durability (QUV)

Qhov kev sim no hauv QUV-weatherometer muaj 2 lub voj voog. Cov coated testpanels yog 8h raug UV-teeb thiab 4h rau condensation. Qhov no rov ua dua thaum 1000h. Txhua 250h cov panels raug kuaj xyuas. Ntawm no cov txheej yog kuaj ntawm cov xim- thiab gloss tuav.

Kev ntsuam xyuas ntsev tsuag

Raws li cov qauv ISO 9227 los yog DIN 50021. Cov hmoov coated panels (nrog ib tug andreas cross scratched nyob rau hauv nruab nrab ntawm cov zaj duab xis) yog muab tso rau hauv ib tug sov so qhov chaw thiab sprayed nrog ntsev. Qhov kev ntsuam xyuas no ntsuas qhov kev tiv thaiv ntawm cov txheej txheem rau corrosion nyob rau hauv ib qho chaw ntsev (xws li ntawm ntug hiav txwv). Feem ntau qhov ntsuas no siv sijhawm 1000h, nrog rau cov tshev ua txhua txhua 250h.

Kesternich - kev xeem

Raws li cov qauv DIN 50018 lossis ISO3231. Muab ib qho kev qhia zoo rau kev tiv thaiv ntawm cov txheej hauv ib puag ncig kev lag luam. Rau ib lub sijhawm tshwj xeeb, lub vaj huam sib luag kuaj tau muab tso rau hauv qhov chaw sov sov, uas muaj sulfur dioxide. Qhov kev sim no tau khiav 24h-lub voj voog nrog tswj txhua 250h.

Florida-test

Nyob rau hauv tsawg kawg yog 1 xyoo cov coated testpanels raug rau tshav ntuj thiab ntub ib puag ncig ntawm Florida, USA. Gloss thiab xim tuav tau raug soj ntsuam.

Kev ntsuas huab cua (tropical climate)

Raws li cov qauv DIN 50017 los yog ISO 6270. Nws raug tua nyob rau hauv ib chav nrog ib puag ncig ntawm saturated humidity, ntawm ib tug txiav txim kub thiab feem ntau nyob rau hauv 1000h. Txhua 250h ib qho kev tswj tau raug tua ntawm cov hmoov coated panels thiab Andreas-cross khawb nrog rab riam los ntawm zaj duab xis hauv nruab nrab. Qhov kev ntsuas no ntsuas qhov qis qis ntawm cov av noo thiab corrosion nyob rau hauv ib puag ncig ntub.

Tshuaj tiv thaiv

Cov tshuaj tiv thaiv feem ntau raug kuaj ntawm cov txheej txheem uas raug saib xyuas, tiv tauj nrog cov tshuaj detergents lossis tshuaj. Cov xwm txheej tsis raug cai. Yog li, cov neeg tsim khoom siv tshuaj kho cov mob hauv kev sib tham nrog tus neeg thov lossis cov neeg siv khoom zaum kawg.

Txhawm rau ntsuas huab cua tsis kam ntawm cov hmoov txheej yog qhov tseem ceeb heev hauv kev siv hmoov txheej.
