1.How los tshawb xyuas qhov zoo ntawm galvanized txheej los ntawm cov tsos?
Cov tsos zoo: high - Cov khoom zoo yuav tsum muaj cov khoom sib txuam " Cov xim yuav tsum yog cov nyiaj ci {{4 4}} dawb lossis me ntsis bluish, uas tsis muaj kev sib daj cua dub, daj, daj, lossis tsaus.
Kev tshuaj xyuas: yuav ceev faj ntawm peb hom teeb meem:
Cov kab hlau tam sim no / nthuav tawm cov hlau dub: xws li cov kab txaij lossis cov kab txaij, tshwm sim rau ntawm {{k} rolled boundplate). Cov chaw no yuav xeb ua ntej, ncaj qha ua rau lub corrosion tsis kam.
Zinc Peexouring / Blistering: maj mam kos saum npoo. Yog hais tias cov txheej zinc txheej lossis npuas, nws qhia tias ib txheej ua haujlwm tsis muaj zog ntawm cov zinc txheej thiab feem ntau vim tsis tiav kev puas tsuaj lossis tsis meej pem galvanizing kub).
Cov Dub Dub / Dawb Xoom: Cov Dub Dub (ntau dhau zinc oxidation) lossis hmoov dawb (zinc ide Tus qub cuam tshuam corrosion tsis kam, thaum lub tom kawg, yog tias lub hauv paus xim tseem niaj hnub hnav tom qab so, tuaj yeem ua kom qhuav los ntawm ziab. Txawm li cas los xij, yog tias zinc txheej peels, nws qhia tau qhov tsis zoo.
2.Yog li cas los tshawb xyuas cov tuab ntawm galvanized txheej?
Cov Qauv Yuav Tsum Tau: Raws li GB / T 2518 "Tsis tu ncua kub {}}}} {{{5}- ob tog, kwv yees li, kwv yees li ntawm 11μm). Rau siab - Corrosion cov ntawv thov (xws li cov ntug dej hiav txwv (xws li cov cheeb tsam dej hiav txwv.
Kev Xeem Txuj:
Rau cov ntawv thov kev ua haujlwm: Siv zinc txheej tuab tuab cov tuab site (sib nqus lossis hom ntawv tam sim no) los ntsuas cov ntawv tuab (tsawg kawg 5 ntsiab lus) thiab coj tus nqi nruab nrab. Yog hais tias tus nqi nruab nrab hauv qab tus qauv, daim ntawv yog suav hais tias tsis tsim nyog.
Kev Txiav Txim Siab Yooj Yim: rau cov nplooj ntawv tuab, siab - Zoo galvanized galvanized falvanized (nrog ntau dua zinc txheej cov ntsiab lus). Hloov lwm txoj kev, yog tias cov nplaim taw yog khawb nrog cov khoom tawv, siab} Cov khoom zoo yuav tsuas yog cov xim zoo heev, thiab zinc txheej yuav tsis yooj yim. (Cov khoom lag luam qis dua yuav nthuav qhia cov hlau thiab zinc txheej yuav poob tawm yooj yim.)
3.Txhua qhov nplaum ntawm galvanized txheej?
Khoov kuaj: Nqa cov qauv me me thiab khoov nws 180 ° (tais (folded hauv ib nrab) los ntawm tes lossis nrog ib qho cuab yeej. Soj ntsuam cov txheej zinc zinc ntawm qhov khoov rau cov kab nrib pleb lossis tev. High - Cov khoom lag luam siab yuav qhia tsis pom cov kab tawg hauv cov kab mob zinc, lossis tsuas yog cov kab plaub hau zoo " Yog tias khoov ncaj qha rau cov hlau lossis zinc txheej nrov nrov tawm, cov nplaum tsis zoo.
Kev kuaj: Siv rab riam hluav taws xob los ua tus ntoo khaub lig - duab square, khawb los ntawm zinc txheej rau lub substrate). Siv 3M daim kab xev thiab tshem tawm sai sai. Yog tias tsis muaj zinc residue tseem nyob ntawm daim kab xev, adhesion yog siv tau.
4.How mus kuaj substrate thiab molding zoo?
Ballboard Thickness: tsis muaj "txiav cov ces kaum"
Kev ntsuas txujci: Siv micrometer (qhov tseeb 0.01mm) los ntsuas ntawm daim ntawv tiaj tus (zam kev tsa ceg ncaj ncees). Nco tseg: cov cim tuab yog tag nrho cov tuab ntawm "baseboard + zinc txheej." Xyuas kom meej tias lub pob tawb tuab raws li kev pom zoo {{}}}}, "0.5} rolled galvanized ntawv"). Lub Hallboard Thickness yuav tsum ≥ 0.48mm, thiab zinc txheej yuav tsum muaj kwv yees li 0.02 hli).
TSWV YIM: Ceev ntawm qhov tsis sib xws ntawm "Nominal tuab" thiab "cov khoom lag luam tuab" Cov txheej zinc ib qho tseem yuav nyias, ua kom muaj zog tag nrho thiab ua rau nws raug kev puas tsuaj rau kev kho hniav thiab ua kom muaj kev ntxhov siab.
Corrugated txoj kev tsim: tsis tu ncua, tsis muaj deformation
Pom cov tsos tshuaj xyuas: saib xyuas cov kev sib xyaw ntawm txoj kev sib txawv ntawm kev siab thiab wavelength (piv txwv li cov ntawv 820 corrugated yuav tsum muaj qhov siab ntawm 80mm). Xyuas kom muaj tsis muaj qhov "Skewed nthwv dej," "tsaus muag" (hauv zos txo qis ntawm txoj kev siab corrugation), lossis "warping" (tsis sib yuav). Flatsness Kuaj: nteg daim ntawv thawv rau hauv av. High - Cov khoom lag luam zoo yuav tsum muaj tsis muaj kev tawm tsam. Nias lub tsa ceg ncaj ncees nrog koj txhais tes. Nws yuav tsum muaj khov kho thiab tsis muaj lub caij ci ntsa iab (ntau tshaj lub chaw ci ntsa iab qhia pom lub zog tsis txaus thiab lub zog tsis zoo). Yog tias muaj cov hniav lossis deformation tom qab nias, nws qhia tau tias lub substrate yog cov txheej txheem muag muag dhau los yog cov txheej txheem tsis zoo.
Vuam / pob qij txha ua tau: Haum rau cov kev xav tau.
Yog hais tias ntawm {-} Kev siv vuam yog qhov yuav tsum tau ua, piv txwv kev sim tuaj yeem ua. Thaum lub sij hawm vuam, txheej zinc ib txwm yuav tsum tsis txhob mus rau qhov yooj yim, thiab Weld yuav tsum dawb ntawm cov kab nrib pleb lossis pores. Tom qab txias, coj mus rhaub weld nrog rab rauj. Yog tias tsis muaj kev pom tawg lossis loj {4 4}} nplai zinc plos, lub substrate yog suav tias yog qhov ua tau rau Weldability. (Tsis zoo {- zoo substrates yuav muaj kev impurities ntau dhau thiab yuav tsum tau tawg ua kom tawg thaum lub sijhawm vuam.)
5.Txoj kev tshawb xyuas qhov chaw zoo thiab qhov tseeb qhov tseeb?
Qhov xwm txheej nto: Tsis muaj kev puas tsuaj lossis paug.
Ntxiv rau qhov tsis xws luag nyob rau hauv galvanized txheej, cov kev tshuaj xyuas hauv qab no yuav tsum muaj:
Tsis muaj qhov khawb lossis cov pits: lub saum npoo yuav tsum tau dawb ntawm khawb av dua li 0.1mm (uas yooj yim dua 5 hli hauv lub taub (uas tuaj yeem cuam tshuam rau cov tsos (uas tuaj yeem cuam tshuam rau cov tsos (uas tuaj yeem cuam tshuam cov tsos mob thiab muaj zog).
Tsis muaj roj stains lossis impurities: lub saum npoo yuav tsum huv, dawb ntawm cov roj pom stains, plua plav, lossis zinc residue. (Cov roj stains tuaj yeem cuam tshuam cov nplaum ntawm txuas ntxiv ua ntej- txheej lossis cov duab kos, thiab impurities tuaj yeem ua rau muaj kev xeb hauv zej zog.)
Qhov tseeb tiag: Haum rau kev teeb tsa.
Ntev / dav: Ntsuas xyuas nrog daim kab xev ntsuas, qhov sib txawv yuav tsum yog 5.995 - 6.005m). Kev sib txawv ntau dhau tuaj yeem tsim cov khoob thaum lub sijhawm sib dhos ua ke, nce txoj kev pheej hmoo ntawm kev txi.
Kab pheeb ces kaum: Nqa cov ntawv sib dhos thiab ntsuas qhov ntev ntawm ob qho tib si kab pheebsonals. Rau siab - Cov khoom lag luam zoo, qhov txawv yuav tsum yog ≤3M. (Ntau tus degiation qhia cov ntawv yog tawm ntawm cov duab, ua cov txheej txheem nyuaj thaum lub sijhawm teeb tsa.)
