1. Thaum muab piv rau tus nqi-kev ua tau zoo ntawm cov xim galvanized-coated coils, qhov taw qhia tseem ceeb twg yuav tsum tau txiav txim siab ua ntej?
Thawj kauj ruam hauv kev sib piv tus nqi-kev ua tau zoo tsis yog saib ntawm tus nqi tsev, tab sis yog nyob ntawm "tag nrho lub neej- nqi mus ncig" rau ib cheeb tsam. Cov ntsiab lus tseem ceeb yog "qhov hnyav ntawm txheej txheej galvanized" thiab "hom thiab thickness ntawm txheej." Piv txwv li, rau 0.5 hli tuab xim-coated coils, ib yam khoom uas muaj galvanized txheej hnyav ntawm 120 grams ib square meter (ob -sided) tej zaum yuav muaj xeb- pov thawj lifespan ob peb zaug ntev dua ib yam khoom nrog galvanized txheej hnyav ntawm 60 grams ib square meter, tab sis tus nqi sib txawv tsuas yog ib puas tonnes. Yog li ntawd, tus nqi -kev ua tau zoo yuav tsum tsis yog tsuas yog txiav txim siab ntawm tus nqi ib tuj lossis ib lub 'meter' xwb, tab sis kuj los ntawm kev suav cov nqi nruab nrab txhua xyoo tshaj li qhov kev pab cuam lub neej. Rau cov chaw ntug dej hiav txwv lossis thaj chaw uas muaj kev lag luam loj heev, xaiv cov khoom uas muaj txheej txheej galvanized ntau dua (xws li 180 grams ib square meter) thiab fluorocarbon txheej, txawm hais tias thawj chav tsev nqi siab dua, yuav tsum tsis muaj kev saib xyuas rau ntau tshaj kaum xyoo, uas ua rau tag nrho cov nqi siab dua -effectiveness.
2. Dhau li ntawm galvanized txheej thiab txheej, lub zog thiab thickness ntawm lub substrate puas cuam tshuam rau tus nqi -kev ua tau zoo?
A: Lub zog ntawm lub substrate txiav txim siab lub load - bearing peev thiab cua uplift kuj ntawm cov qauv. Piv txwv li, rau qib Q235 zoo tib yam thiab cov qauv S350 lossis S550 qib xim -coated coils ntawm tib lub thickness, lub zog tawm los ntawm lub tom kawg yog ntau dua 1.5 npaug ntawm qhov qub. Qhov no txhais tau hais tias nyob rau hauv tsim loads, siv ib tug siab - lub zog substrate tso cai rau txo nyob rau hauv lub thickness ntawm daim ntawv los yog lub purlin qhov sib nrug, yog li txo tag nrho cov steel noj. Thaum sib piv tus nqi-kev ua tau zoo, "cov khoom siv tus nqi yuav tsum muaj ib kilonewton-meter load-bearing peev" yuav tsum raug xam. Yog tias qhov siab -cov ntawv muaj zog raug nqi 800 yuan ntau dua ib tuj, tab sis cov tuab tuaj yeem txo los ntawm 0.6 hli mus rau 0.5 hli, ces tus nqi steel ib square meter yog qis dua, thiab lub ru tsev sib dua thiab nyab xeeb dua -qhov no yog ib qho piv txwv ntawm tus nqi - kev ua kom zoo dua.
3. Yuav ua li cas los sib piv tus nqi -kev ua tau zoo ntawm ntau hom xim txheej (xws li polyester, silicone- hloov polyester, thiab fluorocarbon)?
A: Tus nqi tuaj yeem ntsuas los ntawm "huab cua-resistant lifespan unit price". Cov txheej txheej polyester zoo tib yam yog qhov pheej yig tshaj plaws, tab sis kev lees paub sab nraum zoov feem ntau tsuas yog 5 mus rau 7 xyoo, tom qab ntawd fading, chalking, thiab txawm tias tev tuaj yeem tshwm sim. Silicone-hloov polyester txheej yog kwv yees li 10% mus rau 20% kim dua, tab sis muaj kev tiv thaiv ntawm 10 mus rau 15 xyoo, haum rau cov nroj tsuag kev lag luam. Fluorocarbon coatings yuav raug nqi 1.5 mus rau 2 npaug ntau dua li cov polyester zoo tib yam, tab sis muaj kev lav phib xaub ntau dua 20 xyoo thiab cov xim zoo nkauj thiab gloss. Thaum sib piv, xam cov "cov nqi txheej uas yuav tsum tau muaj rau txhua xyoo lav": yog tias cov polyester zoo tib yam raug nqi 20 yuan ib square meter nrog 5- xyoo warranty, qhov ntawd yog qhov nruab nrab ntawm 4 yuan ib xyoo; fluorocarbon raug nqi 40 yuan ib square meter nrog 20- xyoo warranty, uas yog qhov nruab nrab ntawm 2 yuan ib xyoo. Kom meej meej, fluorocarbon muab kev ua haujlwm ntev dua -tus nqi- ua tau zoo. Rau ib ntus lossis luv luv- lub tsev lub sijhawm, polyester zoo tib yam yog kev lag luam ntau dua; rau cov tsev mus tas li, fluorocarbon yog qhov kev xaiv ua haujlwm siab.
4. Thaum muab cov nqi sib piv -kev ua tau zoo, cov nqi zais thiab kev pheej hmoo dab tsi yog yooj yim saib tsis tau?
A: Muaj plaub lub ntsiab lus yooj yim saib xyuas. Ua ntej, kev ua haujlwm poob: Cov nplooj ntawv tiag tiag muaj qhov dav me me thiab cov duab tiaj tus, ua rau qis qis qis thaum lub sij hawm molding; thaum cov ntawv tsis sib xws feem ntau muaj qhov dav thiab khoov tsis sib xws, ua rau muaj peev xwm ntau tshaj 5% pov tseg ib 10 meters thaum lub sij hawm molding. Thib ob, kev thauj mus los thiab kev cia khoom: Tsawg- xim zoo-coated coils muaj kev khawb tsis zoo; Txawm tias me me pob thaum lub sij hawm thauj mus los yuav ua rau nws kim heev xim puas, yuav tsum tau repainting los yog scrapping. Thib peb, kev txhim kho kev ua haujlwm zoo: Cov nplooj ntawv tiag tiag nrog cov zaj duab xis lubricating yog ib qho yooj yim rau punch thiab rivet, thaum cov ntawv tsis zoo nrog cov npoo ntxhib yog qhov yooj yim rau jamming laum khoom, txo kev tsim kho ceev thiab nce nqi zog. Plaub, tom qab-cov nqi kho vaj tsev: Ib zaug xeb lossis faded, repainting ib square meter nqi tsawg kawg yog 30 mus rau 50 yuan, deb tshaj qhov pib nqi sib txawv. Tsuas yog los ntawm kev muab cov nqi zais cia rau hauv kev suav suav tuaj yeem ua tus nqi tiag tiag -kev ua tau zoo.
5. Puas muaj ib qho yooj yim "tus nqi-kev sib piv cov qauv" lossis cov kauj ruam ua tau zoo?
A: Yog lawm, nws raug nquahu kom siv "Tus Nqi- Performance Performance Performance index=Lub neej ua haujlwm tau txais txiaj ntsig ÷ Cov nqi sib tw (RMB / tuj lossis RMB / meter)", tab sis qhov no yog qhov cuam tshuam rau cov khoom lag luam zoo ib yam thiab kev cog lus lav. Cov kauj ruam ua tau muab faib ua tsib kauj ruam: Ua ntej, qhia meej txog kev siv ib puag ncig (hauv av, ntug hiav txwv dej, cov chaw ua haujlwm acid / alkali, thiab lwm yam) thiab tsim lub neej (5 xyoos, 10 xyoo, 20 xyoo). Thib ob, tau txais cov ncauj lus ntxaws ntxaws los ntawm ntau tus neeg muag khoom, sau qhov hnyav ntawm txheej txheej galvanized, txheej hom thiab thickness, thiab qib substrate. Thib peb, thov cov qauv me me rau nws tus kheej- kuaj: siv ntsev tooj liab rau kev ntsuas ntsev ntsev kom nrawm los yog khawb yooj yim ua raws li dej ntsev rau hauv dej, thiab soj ntsuam lub sij hawm tsim xeb. Plaub, xam tus nqi ib square meter xa mus rau qhov chaw tsim kho (xws li freight, se, thiab poob tus nqi). Thib tsib, hloov qhov lifespan thiab tus nqi rau hauv cov mis, los yog ncaj qha piv "tus nqi qis tshaj tag nrho raws li tus qauv tsim lub neej". Nco ntsoov: qhov pheej yig tshaj feem ntau tsis yog tus nqi tshaj - zoo; tus nqi siab tiag tiag-kev ua tau zoo yog nyob rau hauv qhov kev xaiv uas tuaj yeem ruaj ntseg rau lub neej tsim yam tsis tas yuav tsum tau saib xyuas.
