1.Vim li cas ua ntej-coated steel rolls tsis tshua muaj pwm?
Resins: Xws li polyester, silicone- hloov polyester, polyvinylidene fluoride, thiab lwm yam. Cov siab -molecular- hnyav cov organic tebchaw tsis yog cov as-ham rau pwm.
Pigments: Inorganic hais uas muab xim.
Additives: Xws li stabilizers, leveling agents, thiab lwm yam.
Pwm tsis tuaj yeem siv cov tshuaj no ncaj qha los ua zaub mov kom loj hlob thiab tsim tawm. Yog li ntawd, nyob rau hauv ib qho chaw huv, qhuav, ua ntej-coated yob muaj pwm zoo heev.
2.Ntawm qhov xwm txheej dab tsi yuav pwm tshwm rau ntawm cov xim -coated steel rolls?
Pwm kev loj hlob yuav tsum muaj peb yam mob: cov as-ham, noo noo, thiab qhov kub thiab txias. Lub hauv paus ua rau muaj teeb meem pwm nyob rau saum npoo ntawm pre-coated steel coils feem ntau tsis yog txheej nws tus kheej, tab sis theej:
Cov kab mob ntog: Cov plua plav, cov khoom siv organic (xws li paj ntoos thiab cov khib nyiab pov tseg), thiab lwm cov pa phem nyob rau ntawm txheej txheej, muab cov khoom noj rau pwm.
Ntev dampness: Nyob rau hauv kub, av noo, thiab cua tsis zoo ib puag ncig (xws li breweries, zaub mov ua rhiav, hauv qab daus, tropical coastal cheeb tsam, thiab chav dej qab nthab), condensation yooj yim tsim nyob rau saum npoo los yog nws tseem damp rau ncua sij hawm, tsim kom muaj tej yam zoo rau pwm loj hlob.
Tsis muaj kev saib xyuas: Qhov chaw tsis tu ncua tsis tu ncua, ua rau cov av sib xyaw.
3.Dab tsi yog qhov sib txawv ntawm cov tshuaj tiv thaiv kab mob ntawm cov txheej txheem sib txawv?
Dawb polyester: Feem ntau siv thiab raug nqi - zoo, tab sis nyob rau hauv hnyav, ntub ib puag ncig, av yuav tsub kom yooj yim dua ntawm nws qhov chaw.
High-durability polyester/silicone-modified polyester: Offers better hardness and toughness, a denser and smoother surface, making it less prone to dirt adhesion, easier to clean, and superior to plain polyester in terms of mold resistance.
PVDF: Muaj huab cua tiv thaiv zoo heev thiab nws tus kheej- ntxuav cov khoom. Nws nto yog du heev thiab hydrophobic, ua rau nws nyuaj rau cov plua plav thiab cov kab mob sib kis; txawm lawv ua li ntawd los lawv yeej yooj yim ntxuav los ntawm nag. Yog li ntawd, nws muaj zog tshaj los tiv thaiv - pwm muaj peev xwm nyob rau hauv daim ntawv thov uas yuav tsum tau muaj huab cua tsis kam thiab huv.
Cov txheej txheem ua haujlwm tshwj xeeb: Qee lub tuam txhab muab cov tshuaj tua kab mob, uas suav nrog cov tshuaj tua kab mob tshwj xeeb thiab cov tshuaj tiv thaiv kab mob txhawm rau txhawm rau tiv thaiv kev loj hlob ntawm cov kab mob saum npoo av. Cov khoom no muaj qhov zoo tshaj plaws los tiv thaiv- pwm kev ua haujlwm.
4.Dab tsi yog kev ceev faj rau kev siv cov xim rov qab?
Lub nraub qaum ntawm lub pre-coated coil (rov qab txheej) yog qhov tseem ceeb sib npaug. Yog tias siv sab hauv tsev lossis hauv qhov chaw ntub dej, yuav tsum xaiv cov txheej txheem siab - zoo rov qab. Qee qhov qis- cov txheej txheem rov qab tuaj yeem muaj qhov tsis zoo corrosion thiab tuaj yeem ua rau tsis zoo tom qab raug ya raws ntev, muab cov xwm txheej rau pwm loj hlob.
5.Yuav ua li cas resistant xim -coated steel yob rau pwm?
Kev ua tau zoo heev: Cov txheej txheem nws tus kheej yog pwm- tiv taus, zoo dua rau ntau cov khoom siv hauv tsev (xws li ntoo thiab gypsum board).
Ib puag ncig kev vam khom siab: Hauv qhov chaw ntub dej, plua plav nrog cov pa phem, qhov chaw ntawm txhua yam khoom tuaj yeem tsim pwm, thiab xim -coated coils tsis muaj qhov tshwj xeeb.
Kev xaiv txheej txheej yog qhov tseem ceeb: Hauv qhov chaw uas muaj huab cua ntub, xaiv cov txheej txheem nrog cov npoo zoo dua, kev tiv thaiv huab cua zoo dua, thiab tus kheej zoo dua - cov khoom tu (xws li HDP thiab PVDF).
Kev tsim thiab kev saib xyuas yog qhov tseem ceeb:
Tsim: Ua kom muaj qhov cua zoo thiab tso dej kom tsis txhob muaj sijhawm ntev - cov dej sib xyaw lossis cov dej sib xyaw.
Kev txhim kho: Tsis txhob tsim cov kab tuag uas muaj plua plav thiab noo noo tuaj yeem tsim.
Kev Kho: Kev tu lub ntsej muag tsis tu ncua kom tshem tawm cov av thiab cov khoom noj khoom haus zoo tshaj plaws los tiv thaiv pwm. Ib qho qis - rab phom dej siab thiab cov tshuaj ntxuav tes tsis zoo feem ntau txaus.
