Kev tswj xyuas zoo ntawm cov iav fwj tshuaj pleev ib ce yog muab faib ua ob ntu, ib qho yog kev tswj kom zoo ntawm cov khoom siv raw, thiab lwm yam yog kev tswj xyuas cov khoom zoo.
Kev tswj kom zoo ntawm cov khoom siv raw
Feem ntau ntawm cov iav uas tsim nyob rau hauv kev ua lag luam yog ntau cov khoom ua kom txias yaj nrog dej qab zib-lime silicon ua lub cev tseem ceeb.. Cov khoom siv raw tseem ceeb siv suav nrog: quartz xuab zeb, feldspar, calcite, dej qab zib, lwm.; auxiliary raw khoom suav nrog: Yuanming hmoov, carbon hmoov, Selenium hmoov, oxygen cobalt, lwm. Ntau ntawm cov khoom siv raw no yog cov ntxhia hauv ntuj thiab pob zeb. Qhov zoo ntawm raw khoom txiav txim siab qhov zoo ntawm cov khoom iav. Lub purity thiab particle loj ntawm raw cov ntaub ntawv yuav cuam tshuam rau cov txheej txheem ntau lawm thiab cov khoom zoo ntawm iav.
Txhawm rau kom ntseeg tau qhov zoo ntawm cov khoom siv raw khoom, Cov lus qhia sib raug tau raug tsim los coj kev kuaj xyuas cov khoom siv raw, uas yuav tsum tau ua raws li nruj me ntsis.
01 Raw khoom sampling
(1) Cov khoom siv raw: raws li qhov sib txawv orientations ntawm sab sauv, nruab nrab, qis, sab laug, thiab txoj cai, tsawg kawg yog ob lub ntsiab lus raug coj los ntawm tib qhov tob hauv txhua qhov kev taw qhia;
(2) Cov khoom nyoos hauv hnab: rho tawm ib lub hnab ntawm cov ntaub ntawv raw raws li qhov yuav khoom kom muaj nuj nqis, thiab yuav tsum muaj qee lub sijhawm thaum ua piv txwv, thiab ntxig cov qauv me me rau hauv lub hnab kom tsawg kawg yog 10cm lossis ntau dua;
(3) Qhov sampling ntau ntawm txhua batch ntawm raw khoom yog hais txog 4 kg, thiab txhua tus qauv tau muab tus lej tshwj xeeb raws li cov cai ntawm tus lej batch;
02 Qauv pretreatment
(1) Cov qauv retrieved yog qhuav hauv qhov cub, thiab cov qauv muab faib rau qhov xav tau ntawm kev tshuaj xyuas los ntawm tus qauv faib khoom, ib feem ntawm uas yog siv rau cov qauv khaws cia, ib feem rau particle loj tsom xam, thiab ib feem rau kev txheeb xyuas cov khoom;
(2) Tom qab cov qauv rau kev tsom xam yog hauv av thiab yaj, nws tau npaj rau hauv ib qho kev sim tshuaj rau kev tshuaj ntsuam xyuas (npaj cov qauv kev daws teeb meem rau AAS tsom xam);
03 Particle loj tsom xam
Ib txheej ntawm 10 analytical sieves nrog txawv specifications xws li qhov loj tshaj 3.2mm mus rau qhov tsawg tshaj plaws 0.071mm, thiab sib txawv analytical sieves raug xaiv rau particle loj tsom xam raws li txawv raw khoom yuav tsum tau;
04 Tshuaj ntsuam xyuas muaj pes tsawg leeg
Txhawm rau kom ntseeg tau qhov tseeb ntawm kev tshuaj xyuas tshuaj muaj pes tsawg leeg, Qhov ntsuas ntsuas tau xaiv qhov novAA350 atomic absorption spectrometer los ntawm Jena, Lub teb chaws Yelemees. Txoj kev tsom xam yog hais txog txoj kev pom zoo rau kev tshuaj xyuas tshuaj ntawm dej qab zib-lime-silica iav thiab cov ntaub ntawv raw hauv European iav kev lag luam. Cov khoom kuaj xyuas suav nrog Al₂O₃, Fe₂O₃, CaO, MgO, Na₂O, K₂O, Li₂O, thiab SiO₂ (QC-LAB-006B atomic nqus spectrometer).
Kev tswj cov khoom zoo.
Txhawm rau kom ntseeg tau tias qhov zoo ntawm cov iav fwj tsim tuaj yeem ua tau raws li cov neeg siv khoom xav tau, cov khoom saib xyuas suav nrog: iav muaj pes tsawg leeg, iav ntom, iav npuas, iav xim, thiab iav raj mis tom qab ua cov khoom.
01 iav muaj pes tsawg leeg
Kev tswj cov tshuaj muaj pes tsawg leeg ntawm iav nyob rau hauv cov txheej txheem ntawm iav formula muaj pes tsawg leeg yog qhov yuav tsum tau ua kom paub tseeb tias cov iav fwj zoo. Kev tsom xam ntawm iav muaj pes tsawg leeg yuav ua ob zaug hauv ib lub lis piam, siv atomic absorption spectrometer los ntsuas: Al₂O₃, Fe₂O₃, CaO, MgO , Na₂O, K₂O, Li₂O, thiab SiO₂.
02 iav ntom
Qhov kev hloov ntawm iav ntom ntom ncaj qha qhia seb cov tshuaj muaj pes tsawg leeg ntawm iav yog qhov ruaj khov lossis tsis. Lub iav tsis siv neeg qhov ntom ntom ntsuas ntawm SAINT-GOBAIN OBERLAND yog siv los saib xyuas qhov hloov ntawm iav ntom ntom txhua hnub kom ntseeg tau tias qhov ruaj khov ntawm iav muaj pes tsawg leeg..
03 iav npuas
Tus naj npawb ntawm cov iav npuas ncaj qha qhia qhov zoo ntawm lub xeev melting ntawm cov iav. Tus xaiv seedlab3 npuas ntes ntawm MSC&SGCC tuaj yeem khaws cov duab thiab suav cov npuas > 100 m v iav, thiab tau txais cov iav npuas kom raug thiab sai. Rauv combustion parameters raug kho.
04 iav xim
Tsuas yog los ntawm kev txheeb xyuas cov xim ntawm cov iav tuaj yeem peb saib xyuas cov xim ntawm cov iav thiab ua tiav lub hom phiaj ntawm kev tswj qhov ruaj khov ntawm cov xim iav.. Siv lub SPECORD200 UV / Vis spectrophotometer los ntawm Jena, Lub teb chaws Yelemees, iav tau sim ntawm 330-1100 nm hauv kev sib kis txhua hnub, cov ntaub ntawv tshawb pom tau hloov mus rau hauv xim LAB tus nqi, thiab cov iav xim tau qhia tus lej.
05 Lub raj mis iav tom qab ua cov khoom lag luam
(1) Adhesion test ntawm iav fwj varnishing, silk-screening thiab bronzing khoom
Txhawm rau saib xyuas qhov adhesion ntawm varnished, silk-screened, thiab cov khoom kub-stamped ntawm iav fwj, 100-grid test tuaj yeem ua tau.
(2) Immersion xeem ntawm iav fwj varnished khoom
Txhawm rau saib xyuas qhov adhesion ntawm iav-coated khoom tom qab immersion, yuav ua tau ib tug immersion xeem.
(3) Yellowing resistance test ntawm iav fwj tshuaj cov khoom
Txhawm rau saib xyuas cov qib ntawm kev tiv thaiv kev laus thiab yellowing ntawm iav fwj tshuaj tsuag, kev kuaj lub teeb nrawm tuaj yeem ua tiav.
