Thaum Humidity ntsib Freezing: Xaiv Cov Hlau Coils rau Indonesian Txias Cia

Peb tau muab steel coil rau cov kev tsim kho sab hnub tuaj Asia rau ntau tshaj kaum xyoo. Ntawm txhua daim ntawv thov uas peb pom, qhov txias cia hauv Indonesia ua rau peb ncua sijhawm ntau tshaj. Tsis yog vim tias cov hlau tsis yooj yim los tsim, tab sis vim tias qhov chaw khiav hauj lwm rau txim rau txoj hauv kev uas tsuas yog pom tseeb tom qab lub tsev nce thiab khiav. Txij thaum ntawd los, cov nqi no twb piling.

Koj tab tom sawv hauv -22℃chav txias qhov chaw hauv Jakarta. Sab nraum lub qhov rooj nres, huab cua yog 34℃nrog 85 feem pua ​​​​ntawm cov av noo. Txhua lub sijhawm lub forklift nqa lub pallet tshiab, qhov sov so, noo noo- huab cua rushes rau hauv. Nws tsoo lub qab nthab txias, cov phab ntsa txias cladding, txias steel racking. Instant condensation, uas sai sai tig mus rau Frost. Tshaj li yim teev ua haujlwm, lub qhov rooj qhib ntau zaus. Txhua lub voj voog ntxiv lwm txheej nyias ntawm cov dej khov rau txhua qhov chaw steel.

Thaum lub sij hawm defrost pib nyob rau hauv, lub ice melts. Cov dej ntws mus thiab nkag mus rau hauv cov vaj huam sib luag. Tom qab ntawd qhov kub thiab txias dua thiab dej refreezes, expanding thiab prying cov seams sib nrug. Thaum ib qho kev sib koom ua ke raug cuam tshuam, cov dej noo nkag mus tob dua, txoj cai rau hauv cov tub ntxhais rwb thaiv tsev. Ntau lub hlis, cov sandwich panels nqus dej zoo li daim txhuam cev. Peb tau ntsuas cov vaj huam sib luag uas tau tshaj 500 kilograms ntawm cov dej khov nab kuab. Qhov kev tuag ntxiv ntawd ua rau lub ru tsev thav duab. Hauv ib lub chaw peb tau tshuaj xyuas, tag nrho lub qab nthab tau sagged pom, thiab tus neeg teb xov tooj tsis paub tias yog vim li cas txog thaum peb txiav cov qauv tseem ceeb.

Qhov ntub dej tas li - caij tsheb kauj vab qhuav yog qhov tsis zoo txaus, tab sis yog tias koj qhov chaw nyob ze ntawm ntug dej hiav txwv, huab cua nqa chloride ntsev. Cov ntsev no ua kom cov xeb tsim exponentially. Peb tau pom Z60-galvanized ru tsev panels qhia cov kab liab liab nyob ib ncig ntawm txhua lub fastener hauv ib lub caij los nag. Ntawm phab ntsa - rau-ru tsev hlws ris, seem thickness poob mus txog 37 feem pua ​​tom qab tsuas yog plaub xyoos. Qhov ntawd tsis yog qhov ntsuas qhov ntsuas; uas yog qhov kev ntsuas tiag tiag uas peb tau coj los ntawm Surabaya lub freezer uas tseem ua haujlwm.

Qhov kub qis dua ntxiv lwm txheej ntawm kev pheej hmoo. Ib txwmQ235steel poob cuam tshuam toughness hauv qab -10 degree. Lub forklift pob uas tsuas yog dents ib kem sov tuaj yeem tawg ib qho khov. Qhov tawg ntawd loj hlob nrog txhua qhov thermal expansion thiab contraction voj voog. Thaum kawg lub racking hloov tawm ntawm cov kav dej, thiab koj pom nws thaum pallets tsis swb mus rau hauv lawv cov qhov qhib. Txij thaum ntawd los, cov qauv kev ncaj ncees twb raug cuam tshuam.

Ntau tus neeg cog lus siv luv luv nrog cov tshuaj tsuag - siv cov xim. Hauv chav txias, txawm li cas los xij, cov xim zaj duab xis shrinks ntawm qhov sib txawv ntawm cov hlau substrate. Adhesion tawg, thiab flakes pib tev tawm. Cov flakes poob rau hauv koj cov khoom lag luam -cov nqaij nruab deg khov, nqaij, lossis tshuaj. Ib lub pallet uas tsis muaj paug tuaj yeem raug nqi ntau txhiab daus las. Thiab koj tsis tuaj yeem tsuas kov cov xim thaum hmo ntuj. Txhawm rau rov ua dua, koj yuav tsum ua kom sov hauv chav, tshem tawm cov khoom muag, thiab kaw haujlwm rau ob peb hnub. Cov nyiaj tau los poob thaum lub sij hawm downtime feem ntau dwarfs tej kev txuag los ntawm kev siv pheej yig dua xim nyob rau hauv thawj qhov chaw.

Peb tsis cia siab rau daim ntawv qhia lossis kev kwv yees. Peb khiav cov kev xeem nyob rau hauv tej yam kev mob uas ua raws li tiag tiag Indonesian lub freezer ua haujlwm, thiab peb muab cov ntaub ntawv qhib rau peb cov neeg siv khoom.

Pib nrog steel substrate. Peb hais rauQ355 qis-kubqib. Cov khoom no khaws cov kev cuam tshuam toughness mus rau -40 degree, yog li nws tuaj yeem nqus cov khob txhua hnub los ntawm cov khoom siv tuav tsis tau tawg.

Tom ntej no, saib cov txheej. Rau sab nrauv cladding thiab structural framing nyob rau hauv siab -cov av noo, kub-dip galvanized kauj yog tib txoj kev xaiv. Tab sis koj xav tau ntau tshaj li txheej txheem txheej. Peb qhia qhov tsawg kawg nkaus zinc hnyav ntawm 150 grams ib square meter, uas peb hu ua Z150. Rau tej yaam num nyob rau hauv tsib kilometers ntawm ntug dej hiav txwv, peb xav qhia Z275 los yog txawm Z450. Tom qab galvanizing, peb siv ib txheej passivation thiab hloov tau cov organic topcoat nrog lub iav hloov kub hauv qab -30 degree. Lub tsho tiv no txav nrog cov hlau thaum qhov kub ntawm qhov kub ntawm qhov kub thiab txias mus rau lub freezer txias, yog li nws tsis tawg los yog tev.

Rau cov chaw sab hauv uas koj pom thiab kov txhua txhua hnub, ua ntej- pleev xim rau coil muaj qhov du, pinhole- dawb tag. Cov kauj txuas txuas ntxiv - txheej txheem txheej muab cov adhesion zoo ib yam thoob plaws hauv daim ntawv. Peb tau xa peb cov qauv PPGI rau ntsev-kev tshuaj ntsuam tshuaj rau 1,200 teev, thiab cov txheej txheem khaws cia ntau dua 92 feem pua. Qhov ntawd txhais tau tias tsis muaj flaking, tsis muaj cov khoom paug, thiab tsis muaj nqi rov ua dua.

Txawm tias qhov zoo tshaj plaws coil tsis tuaj yeem khaws lub tsev nrog cov qauv tsim tsis zoo. Peb ib txwm nco ntsoov peb cov neeg siv khoom ntawm peb lub ntsiab lus tseem ceeb.

Ua ntej, tso lub vapor barrier rau ntawm qhov sov so ntawm lub rwb thaiv tsev. Hauv Indonesia, qhov ntawd txhais tau tias lub ntsej muag sab nraud. Thiab kaw txhua qhov kev nkag mus nrog lub hom phiaj- ua khau, tsis yog daim kab xev. Daim kab xev dries tawm thiab tawg nyob rau hauv ob xyoos nyob rau hauv lub zos tej yam kev mob. Peb tau rub tawm daim kab xev uas tau hloov mus ua hmoov av nkig.

Qhov thib ob, nce rwb thaiv tsev thickness zoo tshaj qhov koj yuav siv nyob rau hauv temperate climates. Rau -22℃lub freezer, tsom rau R-50 ntawm lub ru tsev thiab R-40 ntawm phab ntsa. Yog tias koj siv tsawg dua, cov dej lwg poob rau hauv lub vaj huam sib luag tseem ceeb, thiab koj tau txais cov condensation zais uas koj tsis tuaj yeem pom kom txog thaum lub vaj huam sib luag bulges lossis delaminates.

Thib peb, tsim rau thermal txav. Koj cov ncej hlau nthuav dav hauv qab hnub tav su thiab cog lus thaum hmo ntuj. Yog tias koj bolt panels rigidly, cov pob qij txha yuav rhuav tshem lub sijhawm. Siv cov slotted qhov thiab resilient sealants uas haum rau qhov kev txav txhua hnub.

Indonesia tswj hwm SNI cov qauv los tiv thaiv cov tswv tsev. Peb cov coils raug tsim kom tau raws li SNI 07-7033-2004 rau kub-dip galvanizing thiab SNI 3567-2024 rau cov hlau txias. Cov kws tsim qauv tsim qauv yuav tsum siv SNI 1729-2020 thiab seismic code SNI 1726-2019. Peb xa txhua cov khoom xa tuaj nrog daim ntawv pov thawj zeb tiav, thiab peb koom tes nrog koj tus neeg tsim khoom kom ntseeg tau tias qhov chaw ua tiav ntawm qhov chaw nyob tsis zoo los ntawm kev tuav thiab kev teeb tsa.

Peb tau saib cov neeg siv khoom txuag 5 feem pua ​​​​ntawm lawv cov ntsiab lus steel, tsuas yog them 50 feem pua ​​​​ntau dua hauv kev kho hauv tsib xyoos. Hloov cov rusted panels, recoating ntawm structural kab, reinforcement ntawm sagging ru systems-thiab tag nrho cov ntawd thaum lub freezer sawv tas thiab koj cov neeg muas zaub tos rau lawv cov xaj. Tus nqi ntawd los ncaj nraim ntawm koj qhov kev ua haujlwm. Nws tsis yog ib yam uas koj tuaj yeem xa mus rau koj cov neeg siv khoom.

Yog tias koj tab tom npaj lub chaw cia txias hauv Indonesia,xa koj cov qauv tsim rau peb: qhov kev khiav hauj lwm kub, cov ntaub ntawv cov av noo hauv zos, qhov chaw qhov chaw, hom panels koj npaj siab yuav siv, thiab qhov xav tau qhib qhov rooj zaus. Peb yuav ua qauv kev pheej hmoo corrosion rau koj qhov xwm txheej tshwj xeeb, pom zoo rau qhov zoo tshaj plaws txheej txheej, thiab muab cov qauv coj mus kuaj rau koj tus kheej ib puag ncig.

Ua koj qhov kev txiav txim siab ntawm cov ntaub ntawv, tsis yog ntawm kev muag khoom. Koj lub tsev khaws khoom tsim los rau xyoo dhau los. Cia peb ua kom cov hlau ua tau raws li tau cog lus tseg, tsis muaj kev npau suav phem uas los ntawm kev txiav cov ces kaum.
