Dab tsi yog Cov Txheej Txheem Ntau Lawm Rau Kev Ua Loj Terrazzo Slabs?

Cov txheej txheem ntau lawm rau terrazzo slabs loj feem ntau suav nrog cov kauj ruam tseem ceeb xws li kev npaj cov khoom siv raw, batching thiab sib tov, molding thiab nias, kho thiab solidification, sib tsoo thiab polishing, nrog rau kev soj ntsuam zoo thiab ntim rau kev cia. Hauv qab no yog cov lus qhia ntxaws:

Raw khoom npaj

Cement: Raws li cov khoom sib txuas rau terrazzo slabs, cement nrog qib siab zog thiab kev ua haujlwm ruaj khov feem ntau yog xaiv, xws li qib 42.5 lossis siab dua Portland cement thiab Portland cement zoo tib yam, los xyuas kom meej lub zog thiab kav ntev ntawm cov slabs.

Aggregates: suav nrog coarse aggregates (xws li gravel thiab pebbles) thiab nplua aggregates (xws li dej xuab zeb). Qhov loj me me ntawm cov ntxhib sib xyaw feem ntau yog tswj los ntawm 5-20mm, thiab qhov kev ua kom zoo ntawm cov nplua aggregate yuav tsum nyob rau hauv thaj tsam ntawm 2.3-3.0. Cov aggregate yuav tsum nyuaj, huv si, thiab tsis muaj impurities.

Pigments: Siv los muab ntau yam xim rau terrazzo boards, inorganic lossis organic pigments nrog lub teeb pom kev zoo, huab cua tsis kam, thiab tshuaj lom neeg ruaj khov yuav tsum raug xaiv kom ntseeg tau tias cov xim tsis yooj yim ploj thaum siv.

Dej: Siv cov dej huv huv lossis cov dej haus uas tsim nyog, thiab tsis txhob siv cov dej uas muaj cov khoom tsis zoo lossis cov impurities ntau dhau kom tsis txhob cuam tshuam rau lub rooj tsavxwm zoo.

Kev sib xyaw ntawm cov khoom xyaw

Ntsuas cov khoom xyaw: Raws li cov qauv tsim ua ntej sib xyaw ua ke, cov khoom siv hluav taws xob hnyav hnyav yog siv los ntsuas cov khoom raw xws li cement, aggregates, pigments, thiab dej. Xyuas kom meej tias cov proportions ntawm ntau yam raw khoom ua tau raws li qhov yuav tsum tau los xyuas kom meej qhov kev ua tau zoo thiab xim sib xws ntawm lub rooj tsavxwm.

Kev sib xyaw: Muab cov khoom hnyav hnyav rau hauv lub tshuab ua kom sib xyaw kom zoo. Lub sij hawm sib tov yuav tsum tau txiav txim siab raws li cov yam ntxwv ntawm cov khoom siv raw thiab kev ua tau zoo ntawm cov khoom sib tov, feem ntau tsis pub tsawg dua 3-5 feeb, kom sib tov sib xyaw ntau yam khoom siv raw thiab tsim cov khoom sib xyaw.

Tsim thiab nias

Npuag: Tshaj tawm cov khoom sib xyaw kom sib npaug hauv cov pwm pwm. Cov txheej txheem ntaub tuaj yeem ua tau manually lossis mechanically los xyuas kom meej tias cov khoom sib tov sib npaug sib npaug hauv cov pwm, tsis muaj qhov khoob lossis qhov tsis txaus.

Compression molding: Siv hydraulic xovxwm lossis vibrating xovxwm los nias thiab tsim cov khoom sib xyaw hauv pwm. Lub siab nias yuav tsum tau kho raws li cov specifications thiab cov kev cai ntawm lub rooj tsavxwm, feem ntau tswj ntawm 10-30MPa. Thaum lub sij hawm nias, nws yog ib qho tsim nyog los xyuas kom meej lub zog thiab ruaj khov kom ua tiav qhov ceev thiab lub zog ntawm lub rooj tsavxwm.

Kho thiab kho

Demoulding: Tom qab raug nias thiab tsim, daim ntawv yog kho nyob rau hauv pwm rau ib lub sij hawm ntawm lub sij hawm kom txog rau thaum nws muaj ib tug tej lub zog, thiab ces lub demolding lag luam yog nqa tawm. Kev ceev faj yuav tsum tau ua thaum lub sij hawm demolding kom tsis txhob ua rau cov npoo thiab qhov chaw ntawm lub rooj tsavxwm.

Natural los yog steam curing:

Kev tu vaj tse: Muab lub rooj tsavxwm demolded rau hauv qhov chaw zoo thiab qhov chaw qhuav rau kev saib xyuas ntuj. Thaum lub sij hawm txij nkawm, qhov saum npoo ntawm lub rooj tsavxwm yuav tsum tau khaws cia noo thiab tsis tu ncua watered rau kev txij nkawm. Lub sijhawm txij nkawm feem ntau tsis pub tsawg tshaj 7 hnub.

Steam curing: Muab lub rooj tsavxwm tso rau hauv qhov cub tua hluav taws kom ceev cov tshuaj tiv thaiv dej ntawm cov cement thiab txhim kho lub zog thaum ntxov ntawm lub rooj tsavxwm los ntawm kev tswj qhov kub thiab av noo. Qhov kub rau chav kho yog feem ntau tswj ntawm 60-80 degree, thiab lub sijhawm kho yog 4-6 teev.

Sib tsoo thiab polishing

Kev sib tsoo ntxhib: Siv lub tshuab sib tsoo ntxhib los ua ntej zom cov npoo ntawm lub rooj kho kom zoo, tshem tawm cov protrusions, burrs, thiab qhov tsis sib xws ntawm lub rooj tsavxwm saum npoo, thiab ua rau lub rooj tsavxwm ua kom tiaj tus. Kev sib tsoo ntxhib feem ntau siv cov taub hau sib tsoo nrog qhov loj me me, xws li 60-120 mesh pob zeb diamond sib tsoo taub hau.

Kev sib tsoo nruab nrab: Raws li kev sib tsoo ntxhib, siv lub tshuab sib tsoo nruab nrab kom ntxiv zom rau saum npoo ntawm lub rooj tsavxwm, txhim kho qhov flatness thiab smoothness ntawm board nto. Qhov loj me me ntawm lub taub hau sib tsoo siv thaum sib tsoo nruab nrab feem ntau yog 180-240 mesh.

Kev sib tsoo zoo: Kev sib tsoo zoo yog cov txheej txheem tseem ceeb kom ua tiav siab smoothness ntawm lub rooj tsavxwm. Lub tshuab sib tsoo zoo yog siv ua ke nrog cov hmoov nplej zoo sib tsoo taub hau (xws li 320-600 mesh) txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhuam, nws yuav tsum tau muab tshem tawm.

Polishing: Polishing yog txoj kev sib tsoo zaum kawg hauv kev tsim cov terrazzo slabs, siv lub tshuab polishing thiab polishing muab tshuaj txhuam rau polish rau saum npoo ntawm slab, muab daim iav zoo li luster. Qhov saum npoo smoothness ntawm polished board yuav tsum ua raws li cov qauv teev tseg.

Kev soj ntsuam zoo thiab ntim cia

Kev soj ntsuam zoo: Ua kom tiav kev soj ntsuam zoo ntawm terrazzo board tom qab sib tsoo thiab polishing, nrog rau cov tsos zoo, qhov sib txawv ntawm qhov sib txawv, flatness, glossiness, lub zog thiab lwm yam ntsuas. Lub ntsej muag zoo xav kom lub ntsej muag ntawm lub rooj tsavxwm tsis muaj qhov tsis xws luag xws li cov kab nrib pleb, cov npoo ploj thiab cov ces kaum, xim sib txawv, thiab lwm yam; Dimensional sib txawv yuav tsum ua raws li cov txheej txheem tsim nyog; Lub flatness thiab glossiness yuav tsum mus txog rau theem teev; Lub zog yuav tsum ua tau raws li cov qauv tsim.

Ntim thiab khaws cia: Cov ntawv tsim nyog yuav tsum tau ntim kom zoo siv cov thawv ntoo lossis cov thawv ntawv los tiv thaiv kev puas tsuaj thaum thauj thiab khaws cia. Cov boards ntim yuav tsum tau muab cais thiab khaws cia raws li qhov tshwj xeeb, xim, thiab qib, thiab sau npe ua ntej muab khaws cia rau hauv lub tsev rau khoom.
