1.Dab tsi yog lub hauv paus ua rau txheej txheej tawg?
Thaum lub txheej yog khoov, nws raug rau tensile, compressive thiab shear stresses. Kev tawg yog qhov tseem ceeb vim tias cov txheej txheej tau yooj yim (elongation) tsis txaus kom haum rau cov yas deformation ntawm cov substrate, los yog cov adhesion ntawm txheej thiab cov substrate tawg.
2.Yuav ua li cas cov khoom tseem ceeb cuam tshuam rau qhov tawg tsis kam ntawm coatings?
Substrate Hom thiab Pretreatment:
Txheej Txheej: Lub hardness, lubricity, thiab adhesion rau txheej ntawm galvanized steel (GI), zinc-aluminized steel (GL), thiab zinc-aluminium-magnesium alloy (ZAM) txawv, cuam tshuam rau tag nrho cov deformability.
Kev Kho Hniav: Qhov zoo ntawm chromate passivation lossis chromium-dawb passivation ncaj qha cuam tshuam rau txheej adhesion. Tsis zoo adhesion ua rau yooj yim txheej txheej thaum khoov.
Txheej Txheej Txheej:
Txheej Txheej: Qhov no yog qhov tseem ceeb tshaj plaws. Feem ntau:
Polyester (PE): General -lub hom phiaj, nrog qee qhov yooj yim, haum rau feem ntau khoov.
High-Durability Polyester (HDP) / Silicon-Modified Polyester (SMP): Cov huab cua zoo dua, tab sis feem ntau hloov me ntsis dua li cov polyester zoo tib yam.
Yas Sol-Coated Polyester (PVC): Txheej tuab heev (feem ntau yog 200μm), kev ua tau zoo heev, tsim los rau kev sib sib zog nqus, thiab qhov kev xaiv zoo tshaj plaws rau kev tiv thaiv cov kab nrib pleb.
Fluorocarbon Polyester (PVDF): Sab saum toj -tier huab cua tsis kam, tab sis hloov tau yooj yim; feem ntau yog siv rau lub tsev sab nrauv, tsis pom zoo rau kev khoov hnyav.
Txheej thickness: Qhov tuab ntawm txheej, qhov sib txawv ntawm qhov kev ntxhov siab ntau dua ntawm cov txheej sab hauv thiab sab nrauv thaum khoov, thiab qhov yooj yim dua yog tawg. Qhov no yog ib txoj cai dav dav.
3.Yuav ua li cas cov txheej txheem thev naus laus zis cuam tshuam rau kev tawg ntawm cov txheej txheem?
Bending Direction:
Transverse dabtsi yog khoov (perpendicular mus rau dov kev taw qhia): Cov ntaub ntawv pov thawj zoo ductility thiab tsis tshua muaj kev tawg.
Longitudinal dabtsi yog khoov (thaum mus rau lub dov kev taw qhia): Cov khoom muaj qis elongation thiab yog feem ntau ua rau tawg.
Qhov Zoo Tshaj Plaws: Thaum tsim thiab tso cov khoom siv, sim ua cov kab bending perpendicular mus rau dov kev taw qhia.
Bending Ceev:
Kev khoov ntau dhau ua rau muaj kev ntxhov siab sai dua, uas tuaj yeem ua rau pob txha tawg. Tsim nyog txo qhov khoov nrawm pab tso cov khoom siv kev ntxhov siab.
Ambient Kub:
Lub txheej hardens thiab ua nkig ntawm qhov kub thiab txias (tshwj xeeb tshaj yog nyob rau lub caij ntuj no). Ua ntej ua haujlwm nyob rau hauv qhov chaw qis - qhov kub thiab txias, nws raug nquahu kom cia cov ntaub ntawv kom sov rau chav sov.
4.Yuav ua li cas tiv thaiv thiab daws cov txheej txheej tawg thaum lub sij hawm kev yuav khoom?
Txhais koj cov kev xav tau: Qhia meej meej koj qhov tsawg kawg yog dabtsi yog khoov vojvoog thiab dabtsi yog khoov kev taw qhia rau tus neeg muag khoom.
Thov cov kev qhia tshwj xeeb: Thov "T-cov ntaub ntawv kuaj khoov" rau cov khoom thiab paub meej tias nws ua tau raws li koj cov kev xav tau ua.
Xaiv cov txheej txheej tsim nyog: Rau cov khoom ua haujlwm uas xav tau me me- vojvoog dabtsi yog khoov, ntug curling, lossis kos duab sib sib zog nqus, ua qhov tseem ceeb ntawm cov txheej txheem plastisol (PVC) lossis tshwj xeeb siab -kev ua tau zoo khoov- tiv taus polyester txheej.
5.Yuav ua li cas tiv thaiv thiab daws cov txheej txheem tawg thaum lub sij hawm tsim khoom thiab ua tiav?
Optimize layout: Xyuas kom cov kab bending yog perpendicular rau dov kev taw qhia ntawm cov ntawv hlau.
Kho cov txheej txheem:
Txo kev khoov ceev kom tsim nyog.
Hauv qhov chaw qis- qhov kub thiab txias, preheat cov ntawv hlau thiab chaw ua haujlwm (piv txwv li, siv lub tshuab cua sov).
Tshawb xyuas thiab tswj qhov tuag:
Ntxuav cov tuag tsis tu ncua kom ntseeg tau tias qhov chaw sib cuag yog du thiab huv.
Rau cov khoom ua haujlwm tseem ceeb, lub tes tsho tiv thaiv polyurethane tuaj yeem siv los qhwv lub qhov tuag qis kom tiv thaiv cov hlau tawv-rau-hlau kov.
Nce lub vojvoog dabtsi yog khoov: Siv qhov loj tshaj plaws tuaj yeem khoov vojvoog, nyob rau hauv qhov txwv ntawm kev tsim thiab kev tuag specifications.
