Dab tsi yog qhov laj thawj rau qhov thiab qhov pores hauv txheej txheej ntawm terrazzo slabs?

Qhov tshwm sim ntawm qhov thiab qhov hws nyob rau hauv txheej txheej ntawm terrazzo slabs yog ib qho teeb meem zoo, uas muaj feem xyuam nrog cov ntaub ntawv, kev tsim kho, kev tu, thiab kev ua haujlwm tom qab-. Cov hauv qab no yog cov laj thawj thiab cov ncauj lus kom ntxaws:

1, Khoom yam ntxwv
Cov teeb meem zoo nrog cov sib sau ua ke
Qhov sib npaug ntawm qhov sib npaug: Yog tias qhov sib txawv ntawm qhov sib txawv ntawm cov khoom sib xyaw (xws li cov pob zeb crushed, iav flakes) loj dhau, cov khoom me me yuav tsis tau ntim kom nruj, thiab qhov khoob yuav tsim ntawm cov khoom loj, ua rau xoob txheej.
Cov impurities nyob rau hauv aggregates: Sib tov av, plua plav, los yog cov organic teeb meem rau hauv aggregates yuav txo tau lub zog sib txuas nrog cov cement thiab tsim cov ntsiab lus tsis muaj zog.
Kev faib ua feem ntawm cov aggregates tsis tsim nyog: Qhov piv ntawm cov cement rau aggregates yog qhov tsis tsim nyog (xws li kev siv cov cement tsis txaus), ua rau muaj kev sib txuas tsis txaus thiab yooj yim tawg lossis tawg ntawm txheej txheej.
Cov teeb meem zoo cement
Lub zog cement tsis txaus: Siv qis- qib lossis cov cement tas sij hawm tsis muaj zog tom qab ua kom tawv thiab yooj yim hnav lossis tev tawm.
Cov tshuaj tiv thaiv tsis zoo ntawm cov cement thiab aggregates: Qee cov aggregates (xws li pob zeb nrog cov ntsiab lus alkali siab) tau txais cov tshuaj alkali aggregate nrog cov cement, ua kom muaj kev ntxhov siab, ua rau ntog los yog qhov pores.
Ntxiv qhov teeb meem
Kev siv cov khoom siv tsis raug, xws li cov dej reducers, retarders, thiab lwm yam, nrog ntau npaum li cas los yog tsis txaus, yuav cuam tshuam rau cov cement hydration cov tshuaj tiv thaiv thiab ua rau txo qis hauv cov compactness ntawm txheej txheej.
Kev tsis sib haum xeeb ntawm cov xim thiab cov cement: Hauv cov xim terrazzo, cov tshuaj lom neeg ntawm cov xim thiab cov cement tsis sib xws, uas yuav ua rau cov xim tsis sib xws lossis hauv zos tev tawm.

2, teeb meem kev tsim kho
Kev tuav tsis raug ntawm cov theem hauv paus
Cov txheej txheem tsis sib xws: Cov txheej txheem tsis sib xws tuaj yeem ua rau tsis sib xws ntawm cov txheej txheej saum npoo av, thiab cov chaw nyias nyias yuav ua rau tawg lossis qhov.
Lub hauv paus tsis huv: Cov roj seem, cov plua plav ntab lossis cov ntaub ntawv xoob ntawm lub hauv paus txheej yuav txo qhov adhesion ntawm txheej txheej thiab lub hauv paus txheej.
Tsis ua raws li tus neeg saib xyuas interface: Tsis siv tus neeg saib xyuas interface lossis daim ntawv thov tsis sib xws, ua rau delamination ntawm txheej txheej saum npoo thiab txheej txheej.
Kev sib tov thiab paving teeb meem
Kev sib xyaw tsis sib xws: Kev sib xyaw tsis txaus ntawm cov cement, aggregates, dej, thiab cov khoom siv ntxiv, ua rau cov khoom tsis sib xws hauv zos thiab tsim cov cheeb tsam tsis muaj zog.
Tsis sib luag paving thickness: Qhov sib txawv ntawm qhov sib txawv ntawm cov txheej txheej saum npoo yog loj heev, thiab cov chaw nyias nyias yuav hnav los yog tawg.
Kev co tsis txaus: Kev siv cov cuab yeej vibration tsis txaus los yog lub sij hawm tsis txaus ua rau muaj qhov tsis zoo ntawm qhov chaw thiab qhov porosity siab.
Nias thiab ua kom tiav cov teeb meem
Lub sij hawm tsis zoo ntawm calendering: calendering ntxov ntxov (cement tseem tsis tau teem tag nrho) tuaj yeem ua rau ntau qhov chaw ntab slurry; Yog hais tias lub compaction lig dhau lawm (lub cement twb teem), nws yuav tsis tau compacted thiab qhov yuav tsim.
Teeb meem nrog cov cuab yeej calendering: Siv cov cuab yeej calendering tsis tsim nyog (xws li cov phaj hlau uas hnyav dhau los yog lub teeb dhau), lossis siv cov lus qhia tsis sib xws, tuaj yeem ua rau qhov chaw tsis sib xws.
Kev ua tiav tsis tiav: Ua tsis tiav tam sim kho qhov tsis xws luag hauv zos (xws li npuas thiab tawg) thaum lub sijhawm ua tiav, ua rau cov pores seem.
3, Kev tu thiab kev tiv thaiv teeb meem
Kev saib xyuas tsis txaus
Lub sijhawm tu ncua luv: cement hydration cov tshuaj tiv thaiv tsis tiav, txheej txheej lub zog tsis txaus, thiab nws tuaj yeem hnav lossis tawg.
Ib puag ncig kev saib xyuas tsis raug: Tsis tshua muaj kub (qis dua 5 degree) lossis cov av tsis txaus tuaj yeem ncua cov cement hardening thiab ua rau xoob txheej txheej.
Kev tiv thaiv tsis muaj kev tiv thaiv: Thaum lub sijhawm saib xyuas, cov yeeb yaj kiab yas lossis cov ntaub thaiv nyom tsis tau npog, thiab cov dej evaporates sai heev, tsim cov kab nrib pleb.
Thaum ntxov siv los yog hnyav hnyav
Siv ua ntej lub sijhawm txij nkawm tas sijhawm: Lub zog saum npoo tsis ua raws li cov qauv tsim thiab yooj yim puas los ntawm sab nraud quab yuam.
Heavy khoom stacking los yog cuam tshuam: Thaum lub sij hawm tsim kho los yog thaum ntxov siv, hnyav khoom stacking los yog txhua yam cuam tshuam tej zaum yuav ua rau tawg los yog qhov nyob rau hauv lub nto txheej.
4, Tom qab ua cov teeb meem
Kev sib tsoo thiab polishing tsis raug
Kev sib tsoo ntau dhau: Kev sib tsoo ntau dhau thaum lub sij hawm sib tsoo yuav ua rau cov qauv ntog thiab cov qhov.
Kev xaiv tsis zoo ntawm tus neeg saib xyuas polishing: Siv cov tshuaj polishing tsis sib haum lossis lub sijhawm polishing tsis txaus tuaj yeem ua rau lub ntsej muag glossiness thiab hnav yooj yim.
Cov pores tsis tiav: Tom qab sib tsoo, cov pores tsis tau ntim rau hauv lub sijhawm nrog cov ntaub ntawv xws li epoxy resin, uas ua rau cov khoom seem.
Kev tu thiab tu tsis txaus
Acid alkali corrosion: Lub sij hawm ntev raug rau acidic los yog alkaline ntxuav cov neeg ua hauj lwm yuav corrode txheej saum npoo thiab ua rau pore o.
Kev khawb cov khoom tawv: Kev ntxuav nrog cov cuab yeej ntse lossis khawb nrog cov khoom tawv yuav khawb qhov saum npoo thiab tsim qhov pores.

5, Lwm yam
tsim tsis haum
Nyias txheej txheej thickness: Tsis txaus tsim thickness (xws li tsawg dua 20mm) ua rau nws nyuaj rau tiv thaiv kev siv loads thiab nquag tawg.
Txoj kab nqes dej tsis raug: Cov kua dej tsis zoo tuaj yeem ua rau cov dej sib txuam, thiab ntev -so dej yuav ua rau lub zog ntawm txheej txheej tsis muaj zog.
ib puag ncig yam
Kev hloov kub: Kev kub ntxhov ntau zaus (xws li qhov kub thiab txias sib txawv ntawm nruab hnub thiab hmo ntuj) tuaj yeem ua rau thermal expansion thiab contraction ntawm cov txheej saum npoo, ua rau cov kab nrib pleb.
Kev sib haum xeeb ntawm lub hauv paus: Kev tsis sib haum ntawm lub hauv paus yuav ua rau tawg lossis qhov hauv txheej txheej.
Kev tiv thaiv thiab kho cov lus qhia
Ua kom zoo xaiv cov khoom siv: Xaiv cov khoom sib xyaw nrog cov khoom me me thiab tsis muaj impurities, tswj cov qib cement thiab ntau npaum li cas, thiab siv cov khoom ntxiv kom tsim nyog.
Cov txheej txheem kev tsim kho nruj: xyuas kom lub hauv paus txheej yog tiaj tus, huv si, sib tov sib xyaw, paving thickness zoo ib yam, thiab lub sij hawm thiab cov cuab yeej rau nias yog tsim nyog.
Txhim khu kev tswj xyuas: Lub sij hawm tu yuav tsum tsis pub tsawg tshaj 7 hnub, ua kom qhov chaw ntub dej, thiab tsis txhob siv thaum ntxov lossis hnyav.

Cov lus qhia ntxaws ntxaws-kev ua tiav: Sau lub qhov hws kom raws sijhawm tom qab sib tsoo, xaiv cov khoom sib xws, thiab tu thiab tswj xyuas tsis tu ncua.
Rationalization ntawm kev tsim: Tsim kom muaj thickness txaus raws li qhov kev siv scenario los xyuas kom meej ib tug tsim nyog txoj kab nqes.
Los ntawm cov kev ntsuas saum toj no, qhov tshwm sim ntawm qhov thiab qhov pores hauv txheej txheej ntawm terrazzo slabs tuaj yeem txo qis, txhim kho qhov zoo thiab ua haujlwm ntawm qhov project.
