Thaum tag nrho cov nyiaj hauv ntiaj teb kev lag luam tab tom loj hlob, qhov tsis sib xws ntawm cov peev txheej ib puag ncig thiab kev lag luam thiab kev loj hlob ntawm kev sib raug zoo tau dhau los ua qhov tseem ceeb.Environmental pollution tau dhau los ua teeb meem loj thoob ntiaj teb.Raws li kev lag luam iav, peb tuaj yeem pab txhawb kev tiv thaiv ib puag ncig thoob ntiaj teb?
Cov iav khib nyiab tau sau, txheeb, thiab ua tiav, thiab siv los ua cov khoom siv raw rau iav ntau lawm, uas tau dhau los ua txoj hauv kev tseem ceeb rau kev rov ua dua tshiab ntawm cov iav khib nyiab.Cov iav khib nyiab tuaj yeem siv rau hauv kev tsim cov khoom iav uas tsis tshua muaj kev xav tau rau cov tshuaj muaj pes tsawg leeg, xim thiab impurities, xws li lub raj mis iav, iav insulators, hollow iav cib, channel iav, qauv iav thiab xim iav pob.Qhov sib xyaw ntawm cov iav khib nyiab hauv cov khoom no feem ntau yog ntau tshaj 30wt%, thiab qhov sib xyaw ntawm cov iav khib nyiab hauv lub raj mis ntsuab thiab cov khoom tuaj yeem ncav cuag ntau dua 80wt%.
Kev siv cov iav khib nyiab:
1. Cov ntaub ntawv txheej: siv cov iav khib nyiab thiab cov log tsheb khib nyiab pov tseg rau hauv cov hmoov zoo, thiab sib tov rau hauv cov xim hauv ib qho kev faib ua feem, uas tuaj yeem hloov cov silica thiab lwm yam khoom hauv cov xim.
2. Raw cov ntaub ntawv ntawm iav-ceramics: iav-ceramics muaj kev ntxhib los mos, siab mechanical zog, zoo tshuaj thiab thermal stability.Txawm li cas los xij, tus nqi tsim khoom ntawm cov khoom siv raw khoom siv feem ntau siv hauv iav-ceramics yog qhov siab.Nyob rau hauv txawv teb chaws, pov tseg iav los ntawm cov txheej txheem ntab thiab ya tshauv los ntawm cov fais fab nroj tsuag yog siv los hloov cov tsoos iav-ceramic raw cov ntaub ntawv los tsim iav-ceramics ntse.
3. iav asphalt: siv cov iav khib nyiab los ua cov khoom siv rau txoj kev asphalt.Nws tuaj yeem sib xyaw iav, pob zeb, thiab ceramics yam tsis muaj xim sorting.Piv nrog rau lwm cov ntaub ntawv, siv iav los ua ib qho muab tub lim rau txoj kev asphalt muaj ntau yam zoo: kev txhim kho cov kev ua haujlwm ntawm kev sib tsoo ntawm txoj kev pavement;tsis kam rau abrasion;txhim kho qhov kev xav ntawm pavement thiab txhim kho qhov pom kev pom thaum hmo ntuj.
4. Cov iav mosaic: Cov txheej txheem ntawm kev siv cov iav khib nyiab kom ceev cov iav mosaic, uas yog tus cwj pwm los ntawm kev siv cov iav khib nyiab ua cov khoom siv tseem ceeb, siv cov ntaub ntawv tshiab (aqueous tov ntawm kua nplaum), inorganic colorants thiab ua tiav cov khoom sib xws. sintering txheej txheem.Lub molding siab yog 150-450 kg / cm2, thiab qhov tsawg kawg nkaus firing kub yog 650-800 ℃.Nws raug rho tawm haujlwm nyob rau hauv qhov txuas txuas txuas hluav taws xob kiln.Tsis xav tau ua npuas ncauj inhibitor;vim qhov kev ua tau zoo ntawm cov binder, tus nqi me me, thiab nws tuaj yeem raug rho tawm haujlwm sai.Yog li ntawd, cov khoom muaj ntau yam xim, tsis muaj npuas, muaj zog pom kev zoo thiab zoo nkauj zoo nkauj.
5. Artificial marble: Artificial marble yog ua los ntawm cov iav khib nyiab, ya tshauv, xuab zeb thiab gravel raws li aggregates, cement yog siv los ua ib daim ntawv khi, thiab cov txheej txheej saum npoo thiab txheej txheej yog siv rau cov txheej txheem thib ob rau kev kho ntuj.Nws tsis tsuas yog muaj qhov ci ntsa iab thiab ci xim, tab sis kuj muaj lub cev zoo thiab cov khoom siv kho tshuab, ua haujlwm yooj yim thiab zoo nkauj zoo nkauj.Nws muaj cov yam ntxwv ntawm cov khoom siv dav dav, cov cuab yeej siv yooj yim thiab thev naus laus zis, tus nqi qis, thiab kev nqis peev tsawg.
6. Cov vuas iav: siv cov iav khib nyiab, cov khib nyiab ceramic thiab av nplaum ua cov ntaub ntawv tseem ceeb, thiab hluav taws kub ntawm 1100 ° C.Cov iav khib nyiab tuaj yeem tsim cov iav theem hauv cov pobzeb ceramic thaum ntxov, uas yog qhov zoo rau sintering thiab txo qhov kub thiab txias.Cov pobzeb iav no yog siv dav hauv paving ntawm nroog squares thiab hauv nroog txoj kev.Nws tuaj yeem tsis tsuas yog tiv thaiv cov dej nag los ntawm kev sib sau thiab ua kom cov tsheb khiav, tab sis kuj ua kom zoo nkauj ib puag ncig thiab tig cov khoom pov tseg rau hauv cov khoom muaj nqis.
7. Ceramic glaze additives: Hauv ceramic glaze, kev siv cov iav khib nyiab los hloov cov frit kim thiab lwm yam khoom siv tshuaj tsis tuaj yeem txo qhov kub kub ntawm cov glaze, txo cov nqi ntawm cov khoom, tab sis kuj txhim kho cov khoom zoo. .Siv cov iav khib nyiab los ua glaze kuj tseem tuaj yeem txo lossis txawm tias tshem tawm qhov xav tau ntxiv cov xim, kom cov xim hlau oxides txo qis, thiab tus nqi ntawm cov glaze yog txo ntxiv.
8. Kev tsim cov khoom siv thermal rwb thaiv tsev thiab suab rwb thaiv tsev: cov iav khib nyiab tuaj yeem siv los tsim cov rwb thaiv tsev thermal thiab suab rwb thaiv tsev cov ntaub ntawv xws li ua npuas ncauj iav thiab iav ntaub plaub.
