Cov lus muab duab tshiab uas sib xyaw ntau tshaj plaws uas siv nyob rau hauv kev siv cov khoom tshiab no yog cov duab tshiab ntawm ferric oxide. Cov duab tshiab no yog paub tias muaj kev nyab xeeb heev, muaj kev nyab xeeb rau hauv qhov chaw sib xyaw, thiab tsis ua rau nyuaj rau lub ntiaj teb, ces lawv yog qhov tseem ceeb rau cov kev lag luam zoo li cov khoom siv plastic thiab cov khoom siv rau lub duab tshiab. Yog tias yog kom cov khoom muaj duab tshiab zoo dua los yog kom cov khoom muaj kev ua haujlwm zoo dua thaum siv ntev, cov duab tshiab ntawm ferric oxide yog qhov tseeb tias yuav muab duab tshiab rau cov khoom txhua yam, thiab yuav muab duab tshiab rau cov khoom nyob rau hauv txhua qhov kev lag luam. Yog tias tus neeg siv khoom paub tias cov duab tshiab no ua dab tsi rau hauv cov khoom siv plastic thiab cov khoom siv rau lub duab tshiab, lawv yuav tuaj yeem siv cov khoom tshiab uas xwm fab rau kev siv khoom zoo.
1. Puas yog vim li cas cov duab tshiab ntawm ferric oxide yog siv dav
Cov pigment oxide ntawv tsoo yog muaj txiaj ntsig rau lawv cov kev nyab xeeb thiab kev siv los ua qhov tseem ceeb. Cov pigment oxide ntawv tsoo tsis raug txuas los ntawm lub cim, kub thiab cov khoom sib thaug (los ntawm cov pigment organic) thiab vim li no, lawv yog qhov tseem ceeb heev rau cov hauv qhov chaw uas muaj kev sib thaug ntau. Cov pigment no muaj ntau qhov li ntau yam li: daim duab rog, daim duab kub, daim duab dub thiab daim duab ntsuab, uas tuaj yeem sib tshuam los ua daim duab tshiab.
Qhov kev pab ntxiv yog tias lawv yog zoo rau lub ntiaj teb. Cov pigment no tsis muaj txoj cai, nyab xeeb, thiab tau txais cov kev tsaug ntawm cov standards ntawm kev nyab xeeb ntawm lub ntiaj teb, xws li cov oxide ntawv tsoo. Vim li no, lawv tau siv rau cov qhov chaw uas muaj kev txaus siab heev rau kev nyab xeeb thiab rau lub ntiaj teb, xws li rau cov khoom siv rau kev kho, cov khoom siv rau hauv tsev, thiab cov khoom siv rau kev kho cov duab.
2. Cov kev siv rau hauv qhov chaw siv plastic
Cov pigment iron oxide yog qhov tseem ceeb los ua cov khoom sib txawv los ua khoom plastic, los ua cov kab mob plastic, cov tub, cov khoom sib txawv rau kev siv, cov khoom sib txawv rau hauv tsev thiab cov khoom sib txawv rau kev xaiv. Nws muaj qhov teeb meem ntawm kev siv hluav taws xob siab uas pab nws los ua cov khoom plastic nyob rau hluav taws xob siab thaum siv cov kab mob, siv cov kab mob rau kev ua khoom thiab siv cov kab mob rau kev ua khoom los ntawm qhov hluav taws xob.
Nws kuj tau zoo dua los ntawm cov pigment iron oxide uas pab cov khoom plastic muaj qhov tsis muaj kev cuam tshuam ntawm lub cev thiab ntawm qhov chaw nres qhov hluav taws xob. Piv txwv li, cov khoom sib txawv rau kev xaiv li cov tub lossis cov laus plastic yuav tsum muaj qhov tsis muaj kev cuam tshuam thaum siv. Cov pigment iron oxide sib npog rau qhov teeb meem no vim nws muaj kev txaus siab rau lub cev thiab muaj kev txaus siab.
Tib si, cov pigment no kuj muaj kev sib txuas nrog ntau yam polymer, uas pab ua cov khoom plastic muaj qhov tsis muaj kev cuam tshuam. Kev sib txuas siab pab cov neeg ua khoom los ua cov khoom plastic uas muaj qhov tsis muaj kev cuam tshuam thiab muaj qhov nres ntsug.
3. Qhov Txaus Siab rau Lub Tswv Yim Tshuab
Cov pigment iron oxide kuj txaus siab rau lub tswv yim tshuab. Lawv feem ntau yog siv rau cov tshuab rau hauv tsev, cov tshuab rau lub tsev, cov tshuab tiv thaiv qhov cua thiab cov tshuab tiv thaiv. Qhov txaus siab ntawm lawv rau qhov cua thi thiab qhov txaus siab ntawm kev ua haujlwm ntawm cov cheebtsam yog qhov uas pab lawv los siv rau cov tshuab nyob rau hauv qhov chaw uas muaj qhov cua thi thi thiab qhov kev ua haujlwm nyob rau hauv qhov chaw uas muaj qhov cua thi thi thi.
Hauv cov qhov zoo tshaj plaws ntawm cov pigment iron oxide rau cov tshuab, qhov txaus siab tshaj plaws yog lawv tuaj yeem siv los pab muab sia thiab tiv thaiv. Piv txwv li, cov pigment iron oxide feem ntau yog siv los tshuab tiv thaiv qhov tawg rau cov khoom siv ntawm cov neeg siv, cov khoom siv thiab cov khoom siv rau lub tsev. Cov pigment no pab tshem tshem lub sijhawm uas cov tshuab yuav nyob tau thiab muaj sia thiab yuav txaus siab.
Cov pigment iron oxide kuj yog siv rau cov tshuab rau lub tsev los pab muab sia thiab tsis yuav tawg los ntawm qhov cua thi thiab cov kev ua haujlwm ntawm qhov cua thi thi. Qhov no pab tshem tshem lawv los siv rau cov tshuab rau lub tsev ntawm lub tsev, cov tshuab rau lub tsev thiab cov tshuab rau lub tsev.
4. Qhov zoo ntawm kev ua haujlwm rau cov kev siv hauv tsev kho mob
Los ntawm qhov sib npaug ntawm qhov muaj txiaj ntsig, kev ua haujlwm thiab qhov txaus siab, cov thawj tsov nyob preferred iron oxide pigments. Lawv muaj qhov strength ntawm kev khiav qhov xwb uas pab cov thawj tsov nyob ua cov li cas uas lawv xav tau los ntawm qhov ntau ntawm pigment uas tsawg. Thaum chaw twg, qhov txaus siab ntawm lawv txoj cai yog tias lawv sib sood nrog cov plastic resins thiab cov coating blends ntau yam.
Cov iron oxide pigments kuj muaj qhov zoo siab uas pab muab cov particle size tshwj xeeb thiab cov dispersion characteristics tshwj xeeb. Cov lus no yog tshwj xeeb rau kev pab tshem tso cov khoom zoo thaum muab ua haujlwm rau ntau yam.
Xaus
