Q: Puas yog cov xim pleev xim ntawm cov xim galvanized-coated coils ib txwm puas thaum lub sij hawm tsim?
A: Tsis tas li, tab sis muaj kev pheej hmoo ntawm kev puas tsuaj. Yog tias cov xim muaj xim -coated sheet forming cov cuab yeej siv (cov chais yog kho nrog polyurethane lossis roj hmab txheej), thiab cov menyuam sib txawv thiab lub siab raug kho kom raug, kev tsim ib txwm yuav tsis ua rau pom tseeb khawb rau cov xim pleev xim. Txawm li cas los xij, yog hais tias cov menyuam nto yog ntxhib, muaj burrs, los yog nyob rau hauv ib qho nyuaj hlau sib cuag, los yog cov hlau khib nyiab sib xyaw thaum lub sij hawm tsim, khawb, indentations, los yog txawm txheej tev tau yooj yim tshwm sim. Yog li ntawd, seb puas muaj kev puas tsuaj tshwm sim feem ntau yog nyob ntawm cov txheej txheem cov cuab yeej thiab cov txheej txheem kev khiav haujlwm.
2. Qhov twg yog cov xim feem ntau yuav puas thaum lub sij hawm tsim?
A: Muaj plaub qhov chaw tsis muaj zog tshaj plaws: Ua ntej, ob sab ntug ntawm cov sawb, vim tias cov txheej txheej galvanized thiab txheej txheej ntawm cov npoo twb muaj micro- tawg tom qab shearing, ua rau lawv yooj yim rau xim chipping nyob rau hauv siab thaum dov; Thib ob, qhov kev hloov pauv ntawm thaj chaw nruab nrab ntawm cov ncov thiab kwj deg ntawm kev tsim cov corrugations, qhov twg hlau deformation yog qhov hnyav thiab cov txheej txheej stretches tshaj plaws, uas yuav ua rau cov kab nrib pleb zoo; thib peb, sab nraub qaum uas tuaj rau hauv kev sib cuag nrog cov lus qhia chais thiab ntev - teeb tsa baffles thaum pub mis (txawm tias tsis yog qhov tseem ceeb, khawb tuaj yeem ua rau corrosion ntawm sab nraub qaum); thib plaub, thaj tsam ze ntawm qhov txiav tom qab tsim, raws li cov kua muag hlau thaum txiav, ua rau cov txheej txheem tev tawm. Ntawm cov no, pom corrugated saum thiab ribs xav tau kev tiv thaiv tshaj plaws, txwv tsis pub, cov tsos thiab corrosion kuj yuav cuam tshuam.
Peb: Yam dab tsi ua rau kev puas tsuaj rau cov xim pleev xim los ntawm molding?
Teb: Muaj tsib yam tseem ceeb: Ua ntej, qhov kub thiab txias ntawm qhov nruab nrab yog qis dua (qis dua 5 degree), thaum lub sijhawm txheej txheej ntawm qhov yooj yim txo, ua rau nws yooj yim tawg thaum khoov; thib ob, molding ceev ceev heev, ua rau lub txheej tsis muaj sij hawm txaus los kis tusyees; thib peb, cov khib nyiab nyuaj (xws li txiav cov ntaub ntawv hlau lossis cov khoom abrasive) ua raws li cov chais, ua zoo li cov ntawv xuab zeb ntawm cov xim pleev xim; thib plaub, txheej txheej ntawm lub rooj tsavxwm tsis sib haum rau cov kev cai molding, piv txwv li, siab -hardness tab sis qis- yooj fluorocarbon coatings yog feem ntau ua rau tawg dua polyester txheej nyob rau hauv complex waveforms; Thib tsib, kev cia khoom tsis raug ntawm lub rooj tsavxwm ua ntej molding ua rau saum npoo kom nqus plua plav lossis roj, thiab cov khoom no raug nias rau hauv cov xim pleev xim rau hauv cov yeeb yaj kiab thaum molding, ua rau cov pits.
4. Yuav ua li cas kom tsis txhob muaj xim puas thaum lub sij hawm molding los ntawm kev hloov khoom siv?
A: Ua ntej, tag nrho cov menyuam qhov chaw nyob rau hauv kev sib cuag nrog cov txheej yuav tsum tau them nrog polyurethane los yog roj hmab tes tsho, los yog siv steel rollers polished rau ib daim iav tiav thiab nyuaj chrome plated. Ib qho yooj yim steel rollers nrog xeb lossis welds raug txwv. Qhov thib ob, tus nqi nias ntawm txhua tus menyuam yuav tsum tau nce ntxiv kom tsis txhob muaj kev sib tw hauv zos ntau dhau los ntawm ib qho - sij hawm molding. Feem ntau, yam tsawg kawg yog 12 rollers yog xav tau rau gradual molding. Thib peb, nruab ib lub tshuab cua tshuab thiab txhuam txhuam ntawm qhov kawg pub kom tshem tawm cov plua plav tawm ntawm lub rooj tsavxwm, thiab tsis tu ncua siv cov khoom siv tshwj xeeb- raws li cov roj nplua nyeem (tsis muaj roj silicone kom tsis txhob cuam tshuam cov txheej tom ntej lossis kev sib txuas) rau cov menyuam. Thaum kawg, muab lub rooj tsavxwm tso rau hauv lub rooj cob qhia tsawg kawg 24 teev ua ntej molding kom lub rooj tsavxwm kub siab tshaj 15 degree.
5. Yog tias muaj kev puas tsuaj me me rau cov xim pleev xim tom qab molding, nws yuav tsum kho li cas?
A: Rau kev puas tsuaj uas tsis nthuav tawm lub hauv paus hlau (tsuas yog khawb ntawm lub txheej tab sis cov zinc txheej tsis zoo), siv cov xim pleev xim acrylic ntawm tib xim raws li cov xim ua ntej -coil coated los siv rau hauv cov pob. Tom qab ziab, smooth nws nrog ib daim ntaub mos. Rau cov khawb uas nthuav tawm cov zinc plating, ua ntej maj mam xuab zeb tshem cov xim pleev xim nrog cov ntawv xuab zeb zoo, tom qab ntawd siv zinc- nplua nuj primer, thiab tom qab nws qhuav, npog nws nrog topcoat. Rau kev puas tsuaj loj ua rau lub hauv paus hlau (nrog rau cov pob zeb xeb), koj yuav tsum xub ntxuav cov xeb nrog cov xeb tshem tawm cov cwj mem, siv ob -cov khoom siv epoxy resin sealing primer, thiab thaum kawg siv lub tsho tiv no. Tom qab txhua qhov kev kho, siv lub tshuab ziab plaub hau kom ci ntawm qhov kub qis (kwv yees li 60 degree) kom nrawm kho, thiab xyuas kom meej tias thaj chaw kho kom ntev li 5 hli dhau ntawm qhov kev puas tsuaj tiag tiag los tiv thaiv corrosion yav tom ntej los ntawm qhov pib ntawm qhov ntawd. Tsis txhob siv cov xim zoo tib yam los yog daim kab xev pob tshab los npog qhov kev puas tsuaj, vim qhov no yuav ua kom cov electrochemical corrosion nyob hauv qab.
