Cov pigment iron oxide noj qhov tseem ceeb rau qhov kev sib tw ntawm qhov kev sib tw los color concrete, cov khoom cement, cov paving blocks, cov roofing tiles thiab cov khoom sib tw lwm yam. Cov pigment zoo tsis yog tias ua kom muaj qhov xav tshaj plij xwb, tab sis kuj ua kom muaj qhov nyob ntev, muaj kev nyob hauv qhov roj thiab muaj kev nyob ntev ntawm qhov liab. Tiamsis, qhov ntau ntawm cov pigment uas muaj nyob rau hauv tsev tshawb xyuas nyob no yuav pab tsis tau txhawj xeeb rau kev xaiv cov pigment iron oxide uas xav tau los sib tw. Qhov handbook no yuav pab koj paub cov qhov tseem ceeb uas koj yuav tsum nrhiav xyuas thaum koj xaiv cov pigment iron oxide zoo los sib tw rau concrete thiab cov kev sib tw.
1. Nrhiav xyuas qhov liab thiab qhov tshwj xeeb ntawm cov pigment
Qhov liab tshaj plij yog ib qho ntawm cov qhov tseem ceeb tshaj plij ntawm cov pigment iron oxide zoo. Cov pigment uas muaj qhov liab tshaj plij yuav tsum siv ntau dua los ua qhov liab, thiab vim li cas lawv yuav pab txo qhov cost ntawm kev ua haujlwm thiab tso cia qhov liab tshaj plij.
Kev sib xws thiab kuj yog qhov tseem ceeb heev. Qhov sib txawv ntawm li cas yuav ua rau muaj qhov sib txawv uas tuaj yeem pom tau rau hauv cov ntaub ntawv sib txawv, piv txwv li cov ntawv concrete lossis cov ntawv paving stones. Thaum muaj kev xaiv cov pigment uas muaj kev sib xws ntawm li cas, cov thawj tswv uas muaj kev tsim cov pigment yuav tso cai rau kev tswj hwm qhov kev tsim cov pigment rau txhua qhov batch kom muaj kev sib xws ntawm li cas.
2. Tshawb xyuas kev nyab xeeb rau cuab yeej thiab kev nyab xeeb
Cov ntaub ntawv sib tsim yuav tsum tau txais kev txhawb nqa los ntawm qhov roj tsuag, qhov dej, thiab kev sib txawv ntawm qhov cua thiab lwm yam khoom uas muaj nyob hauv qhov chaw. Yog li ntawd, cov pigment iron oxide uas siv rau hauv concrete yuav tsum muaj kev nyab xeeb rau cuab yeej thiab kev nyab xeeb rau UV.
Cov pigment iron oxide uas tsis muaj kev sib txawv yog cov uas muaj kev zoo thiab muaj kev nyab xeeb heev, uas yog qhov uas paub tias nws tsis yuav poob li cas los ntawm lub neej thiab tsis yuav ploj. Qhov no pab tshem cov khoom concrete uas muaj li cas, piv txwv li cov paving stones, cov ntawv rau lub toj, thiab cov concrete uas muaj li cas, kom muaj kev sib xws ntawm li cas rau xyoo ntau xyoo, tsaug rau kev nyab xeeb hauv qhov chaw.
3. Txiav txhua qhov kev tso cua hauv concrete
Lwm qhov tshwj xeeb uas koj yuav tsum xyuam xyuam thaum xaiv cov pigment iron oxide los siv hauv cov khoom sib xyaw yog kev tso cua zoo. Thaum siv cov pigment hauv cov cement mixture, koj yuav tsum ua kom cov pigment tau tso cua raws li qhov tseem ceeb rau kom tsis muaj qhov ntsiab ntawm cov duab thiab cov npov.
Cov pigment zoo tau ua los ntawm cov particle size thiab cov surface properties zoo tshaj plaws uas pab cov pigment tau tso cua rau hauv cement, qia, thiab cov lwm yam khoom sib xyaw tsis muaj teeb meem. Kev tso cua zoo yuav pab txo qhov kev pom ntawm cov khoom concrete thiab pab tshaj plaws rau kev ua haujlwm.
4. Tso cai rau kev nyob ntseg thiab kev sib thaj ntawm cov khoom sib xyaw
Cov concrete mixture muaj cement, dej, cov khoom sib xyaw, thiab nyob rau hauv qee zaug muaj cov chemical admixtures. Cov iron oxide uas koj yuav siv yuav tsum nyob ntseg thiab tsis muaj kev sib kub nrog cov khoom no.
Cov pigment iron oxide tshaj plaws tsis tuaj yeem sib koom nrog alkali, acid thiab cov kev ua haujlwm ntawm cement hydration. Cov kev txaus siab ntawm qhov kev sib koom ntawm kev ua haujlwm no yog qhov pab tau kom cov pigment tsis sib koom nrog cement lossis cov khoom siv ntxiv, thiab yog li ntawd, tsis txhob muab kev puas tsuaj rau qhov kev txaus siab thiab kev txaus siab ntawm cov khoom concrete thaum plav.
5. Xaiv tus thawv uas muaj kev nyab xeeb
Thaum suav tom qab, nej yuav tsum nrhiav tus thawv uas muaj kev nyab xeeb kom tau cov pigment uas muaj kev nyab xeeb thiab muaj qhov zoo tshaj plaws. Tus thawv uas muaj kev nyab xeeb yuav muab cov kev pab tshwj xeeb los ntawm kev siv cov khoom zoo, kev test qhov zoo ntau dua, thiab kev pab txog qhov kev siv khoom los pab cov neeg siv khoom kom tau qhov kev siv khoom uas nej xav tau rau cov kev siv khoom ntawm qhov chaw sib xyaw.
Peb yog RunhuaBang, tus thawv uas muaj cov pigment iron oxide uas muaj kev ua haujlwm zoo rau siv rau hauv cov concrete blocks, paving stones, roof tiles thiab cov khoom siv hauv qhov chaw sib xyaw lwm yam. Cov pigment ntawm peb muaj qhov zoo tshaj plaws ntawm kev muaj lub cev zoo, kev txaus siab rau qhov cim thiab kev txaus siab rau hauv cov cement systems.
Xaus
Kev xaiv cov pigment iron oxide uas xav tau yog qhov tseem ceeb rau qhov zoo thiab qhov kev pom ntawm cov khoom siv rau kev kawm thiab concrete. Cov thawj khoom tuaj yeem tau cov khoom siv rau kev kawm uas yuav nyob ntev thiab muaj kev pom zoo los ntawm kev nco ntsoov rau qhov hloov, qhov nyob ntev, qhov ua haujlwm saib, qhov staub ntawm kev ua haujlwm ntawm kev ua haujlwm, thiab qhov zoo ntawm cov thawj khoom.
Yog tias koj tsis tau txais cov pigment iron oxide uas zoo thiab tuaj yeem siv rau koj cov kev kawm, ces koj tuaj yeem coj cov pigment professional los daws qhov teeb meem no kom ua zoo dua thiab ua rau kev ua haujlwm zoo dua.
