Qhov saum npoo degreasing ntawm galvanized square raj yog ib txoj kev tu raws li cov nyhuv tshuaj alkali.Vim nws txoj kev siv yooj yim, tus nqi qis thiab cov khoom siv tau yooj yim, nws yog dav siv.Vim tias cov txheej txheem ntxuav alkali cia siab rau saponification, emulsification thiab lwm yam teebmeem, qhov kev ua haujlwm saum toj no tsis tuaj yeem ua tiav nrog ib qho alkali.
Feem ntau, ntau yam khoom siv yog siv, thiab qee zaum surfactants thiab lwm yam kev pabcuam yuav tsum tau ntxiv.Lub alkalinity txiav txim siab qib ntawm saponification cov tshuaj tiv thaiv, thiab cov alkalinity siab txo qhov nro ntawm cov roj stain thiab tov, ua cov roj stain yooj yim rau emulsify.Tsis tas li ntawd, tus neeg saib xyuas qhov seem ntawm qhov chaw ntawm galvanized square raj tuaj yeem raug tshem tawm los ntawm kev ntxuav dej tom qab ntxuav alkali.
Nws yog ib txoj kev tshem tawm roj siv dav siv los siv cov surfactant uas tsis tshua muaj qhov nro, zoo permeability thiab wettability, thiab muaj zog emulsification muaj peev xwm.Los ntawm cov nyhuv emulsification ntawm surfactant, lub ntsej muag lub ntsej muag lub ntsej muag nrog qee lub zog yog tsim los ntawm cov roj-dej interface, uas hloov lub xeev interface thiab tus nqi ntawm Wuxi galvanized square tube, kom cov roj cov khoom tawg mus rau hauv cov tshuaj aqueous. ib emulsion.Los yog cov roj stain insoluble nyob rau hauv dej ntawm lub galvanized square raj yuav yaj nyob rau hauv lub surfactant micelle los ntawm lub dissolution nyhuv ntawm surfactant, thiaj li mus hloov cov roj stain rau cov aqueous tov.
Galvanized square raj yog ib hom lub teeb nyias-walled steel raj nrog hollow square seem, uas tseem hu ua steel txias-tsim seem.Nws yog ib hom ntawm cov hlau seem nrog square seem loj, uas yog ua los ntawm Q235 kub dov los yog txias dov sawb hlau los yog coiled phaj raws li cov khoom siv hauv paus tom qab txias dabtsi yog khoov thiab sib sau thiab ces high-frequency vuam.Ntxiv nrog rau cov phab ntsa tuab, lub kaum sab xis thiab ntug ncaj ntawm qhov kub-dov ntxiv tuab phab ntsa square raj ncav cuag lossis txawm tshaj li qib ntawm kev tiv thaiv welded txias tsim square raj.
Qhov zoo ntawm kev khoov tiag tiag yog me me rebound, raug tsim, thiab cov yob zoo nkaus xwb.R ntawm lub kaum sab xis sab hauv yog qhov tseeb dua.Qhov zoo ntawm qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoobLub hollow dabtsi yog khoov tuaj yeem khoov lub kaum sab hauv nrog R <0.2t yam tsis tau rhuav cov yeeb nkab phab ntsa.
Qhov tsis xws luag ntawm kev khoov tiag tiag yog tensile / thinning nyhuv.
Qhov tseeb dabtsi yog khoov yuav ua rau qhov chaw bending stretch, thiab cov nyhuv stretching yuav luv luv longitudinal ntev ntawm txoj kab dabtsi yog khoov;Cov hlau ntawm cov khoom khoov yuav ua thinner vim stretching.
Qhov tsis xws luag ntawm khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob , tsim cov npoo tsis ruaj khov, txoj kab uas hla loj galvanized square tube, thiab tseem yuav cuam tshuam rau kev ua haujlwm ruaj khov ntawm chav tsev thiab kev ua haujlwm zoo.Qhov no kuj yog qhov txawv ntawm qhov hollow dabtsi yog khoov ntawm galvanized square raj.
