Xim rau ntawm galvanized txheej, kev sib khi quab yuam ntawm ib leeg thiab ci kub ntawm cov xim muaj kev sib raug zoo, tom qab galvanized txheej alkyd xim, adhesion tsis muaj teeb meem.Galvanized amino xim, xim adhesion tsis zoo.Ua ob lub hauv qab ob qhov chaw, adhesion yog ok, yog tias ob lub hauv qab ob sab mus rau ob hauv qab peb nto, uas yog, ntau xim, ntau ci ib zaug, rov kuaj adhesion tsis zoo, tsis zoo rau cov xim los ntawm cov galvanized txheej torn. tawm.
Tsis muaj adhesion xeem ntawm cov hmoov txau los yog fluorocarbon txau rau ntawm cov pob galvanized xaim, tab sis muaj ob lub ntsiab lus rau kev siv: ua ntej, nyob rau hauv ib puag ncig kaw los yog tsis muaj huab cua, tsis yog xim hlau volatiles tuaj yeem corrode zinc txheej;Qhov thib ob, zinc ntawm siab tshaj 230 degrees (c) yuav ua rau cov hlau matrix nkig.Thiab cov hmoov txau thiab tshuaj fluorocarbon yuav tsum tau ci ntawm qhov kub thiab txias thiab nyob rau hauv ib puag ncig kaw, ua rau corrosion sai ntawm zinc, uas ua rau xoob corrosion zaj duab xis uas ua rau txheej adhesion poob, thiab txawm ua rau (matrix) steel hlau brittle qhov teeb meem yuav tshwm sim. .
Vim lub pre-tension muab rau lub ntim thiab khi ntawmgalvanized hlau, nws muaj cov yam ntxwv zoo heev ntawm tus nqi qis, kev ntxhov siab me me, kev ruaj ntseg zoo tom qab thauj khoom, tsis yooj yim rau deformation, tsis muaj pob txha, muaj zog elasticity, zoo tib yam steel kab thiab rebar yog nyuaj rau piv.Kev siv cov txheej txheem galvanized tiav, yog li ntawd, kev siv cov kub-dip galvanized steel hlau siv, tsis tsuas yog zoo corrosion kuj, tab sis kuj zoo nkauj thiab dav.Cov khoom muaj cov yam ntxwv ntawm du nto, siab qhov tseeb, zoo uniformity ntawm zinc txheej thiab muaj zog adhesion.
