2.Dab tsi yog lub hauv paus ntsiab lus thiab cov yam ntxwv ntawm kev kuaj tshuaj ntsev ntsev?
Cov Khoom Siv Tseem Ceeb: Cov Tshuaj Txhaum Tshuaj Ntsuam Chamber.
Test Principles: Tsim kom muaj qhov kub thiab txias ib puag ncig nrog cov tshuaj tsuag tsis tu ncua los yog acidic ntsev. Qhov no feem ntau ntsuam xyuas cov txheej txheem corrosion, adhesion, thiab khawb propagation (kuaj kuaj) muaj peev xwm. Qhov no yog qhov tseem ceeb tshwj xeeb rau kev ntsuas kev tiv thaiv ntug kev ua haujlwm.
Test Standards:
ASTM B117: Cov txheej txheem ua haujlwm rau kev kuaj ntsev tsuag.
ISO 9227: Artificial Atmosphere Corrosion Testing - Kev ntsuas ntsev tsuag.
Cov Kev Ntsuas Kev Ntsuas Feem Ntau: Tom qab qee lub sij hawm sim (piv txwv li, 500h, 1000h), tshuaj xyuas qhov chaw rau blistering thiab xeb, thiab ntsuas qhov dav ntawm corrosion kis (chav tsev: mm) ntawm ib sab ntawm khawb.
3.Dab tsi yog lub hauv paus ntsiab lus tom qab damp kub ua haujlwm kuaj?
Lub hauv paus ntsiab lus ntawm kev xeem: Kev ntsuas ntsuas cov txheej blistering thiab adhesion degradation nyob rau hauv qhov kub thiab txias (piv txwv li, kub 40℃± 2 degree, txheeb ze humidity saum 95%).
Test Standard: ASTM D2247 los yog ISO 6270 (condensation immersion test).
4.Dab tsi yog lub hauv paus ntsiab lus tom qab kev ntsuam xyuas sab nraum zoov?
Lub hauv paus ntsiab lus ntawm kev xeem: Cov qauv yog raug rau ntev - lub sij hawm raug nyob rau hauv qhov tseeb, sawv cev rau sab nraum zoov ib puag ncig (xws li thaj chaw muaj kev lag luam, ntug hiav txwv dej, thaj chaw nyob deb nroog, suab puam, thiab lwm yam). Qhov no yog txoj kev muaj tiag thiab txhim khu kev qha, tab sis lub sijhawm ntev heev (feem ntau ntsuas hauv xyoo).
Qhov chaw tseem ceeb: Ntiaj teb-cov chaw muaj npe nrov xws li Florida (qhov kub thiab txias, muaj zog UV hluav taws xob, cov av noo siab) thiab Arizona (qhuav cua sov, muaj zog UV hluav taws xob) hauv Tebchaws Meskas, thiab Guangzhou, Dunhuang, thiab Mohe hauv Suav teb (xws li cov cua sov, cua sov qhuav thiab plua plav, thiab huab cua txias, raws li).
Test Standards:
ASTM G7: Tus txheej txheem rau kev kuaj lub ntuj aging ntawm cov ntaub ntawv nonmetallic sab nraum zoov.
TS EN ISO 2810 Cov xim thiab cov kua roj vanish - Cov lus qhia rau kev laus ntawm ntuj tsim.
Kev ntsuas ntsuas: Cov qauv raug coj mus sij hawm (xws li, txhua txhua 6 lub hlis, 1 xyoos, 2 xyoos, 5 xyoos) los ntsuas qhov kev ua tau zoo tag nrho, suav nrog cov xim sib txawv, gloss, chalking, mildew, thiab corrosion.
5.Cov qauv ntsuas kev ua tau zoo yog dab tsi?
Kev muab qhab nia thiab kev ntsuam xyuas: Cov qib sib txawv ntawm cov xim -coated coils sib haum rau cov kev xeem sib txawv. Piv txwv li:
Ordinary Polyester (PE) Txheej: Feem ntau yuav tsum tau kuaj QUV Ntau dua lossis sib npaug li 600 teev thiab nruab nrab ntsev tsuag (NSS) Ntau dua lossis sib npaug li 500 teev tsis muaj xeb liab.
Huab cua siab -Resistant Polyester (HDP)/Silicone-Modified Polyester (SMP) Txheej: Feem ntau yuav tsum tau QUV Ntau dua lossis sib npaug li 1000 teev thiab tshuaj tsuag ntsev ntau dua lossis sib npaug li 1000 teev.
Polyvinylidene Fluoride (PVDF) Txheej: Feem ntau yuav tsum tau QUV Ntau dua lossis sib npaug li 2000 teev thiab ntsev tsuag ntau dua lossis sib npaug li 1000 teev, sawv cev rau qib siab tshaj.
Warranty Basis: Zoo-paub xim-coated coil manufacturers (xws li Bluestar, Yieh Phui, Baosteel, thiab lwm yam) muab 10-xyoo, 15-xyoo, 20-xyoo, lossis ntev dua kev lav zoo. Lub hauv paus tseem ceeb rau cov kev lees paub no yog los ntawm kev sib raug zoo thiab kev sib piv ntawm lawv qhov chaw sim nruj nrawm nrawm cov ntaub ntawv kuaj kev laus thiab cov ntaub ntawv pov thawj sab nraum zoov mus ntev.
