Txawm hais tias lub npe "Hatschek Machine" thiab "Flow-on Process" tej zaum yuav tsis paub rau koj, cov txheej txheem no zoo ib yam li cas kas fes ua: muaj cov tshuab espresso thiab ncuav- dhau lub tshuab kas fes, ob qho tib si muaj ib pab pawg neeg nyiam thiab ntau yam zoo.
Lub Tshuab Hatschek-Tus "Founding Father" ntawm Fiber Cement Boards
Xyoo 1900, Austrian engineer Ludwig Hatschek tau tsim lub tog raj kheej -pwm txoj kev; qhov no tau cim qhov pib ntawm keeb kwm ntawm fiber ntau cement boards. Ntseeg nws lossis tsis ntseeg, ntau tshaj li ib puas xyoo tom qab, qhov "cov neeg ua haujlwm qub" no tseem mob siab ua haujlwm hauv cov chaw tsim khoom loj thoob plaws ntiaj teb.
Nws txoj kev khiav hauj lwm yog me ntsis zoo li ua ib qho xuas tes ua pastry. Lub slurry yog diluted mus rau ib qho tsis tshua muaj concentration (xws li ntawm 2% mus rau 10%) thiab ntws mus rau hauv ib tug series ntawm rotating mesh cylinders. Txhua lub mesh cylinder khaws ib txheej nyias ntawm cov khoom siv los ntawm slurry; Feem ntau, peb mus rau rau lub tog raj kheej yog teem rau hauv series, stacking txheej rau txheej. Thaum kawg, cov khaubncaws sab nraud povtseg no raug mob rau ntawm lub nruas tsim thiab nias rau hauv ib lub ntom ntom ntom ntom ntom ntom ntom.
Qhov zoo tshaj plaws ntawm cov txheej txheem no yog nws qhov siab ceev. Cov Boards uas tsim los ntawm Hatschek txoj kev muaj ib qho kev sib txuam nrog cov qauv, nrog qhov ntom ntom muaj peev xwm tshaj 1.2-1.5 g / cm³. Tsis tas li ntawd, kev taw qhia ntawm cov fibers hauv lub rooj tsavxwm tuaj yeem tswj tau-ua raws li cov kev taw qhia ntawm cov qauv kev ntxhov siab- ua rau muaj kev siv fiber ntau. Yog li ntawd, cov laug cam uas tsim los ntawm txoj kev no yog qhov muaj txiaj ntsig zoo - haum rau cov kev thov xws li cov phab ntsa sab nrauv thiab cov ntaub thaiv phab ntsa, qhov uas yuav tsum tau muaj zog yog qhov tseem ceeb.
Ntawm chav kawm, lub system tsis yog tsis muaj nws flaws. Cov cuab yeej nta ib tug complex qauv thiab yuav tsum tau ntau yam upfront peev; Tsis tas li ntawd, vim muaj ntau ntau ntawm cov txheej txheej, muaj qee zaus muaj kev pheej hmoo ntawm delamination. Tsis tas li ntawd, qhov tsis tshua muaj siab ntawm slurry yuav tsum ua tiav ntawm cov dej ntau ntawm cov dej rov qab thaum lub sijhawm tsim khoom, ua rau muaj qhov ntim ntau dua ntawm cov dej khib nyiab.
Qhov Flow-Nyob rau txheej txheem-Kev nce qib-thiab-Tom ntej Contender
Thawj qhov sib txawv ntawm Flow- ntawm Txheej Txheem thiab Hatschek txoj kev yog nyob rau hauv qhov tseeb tias cov slurry tsis dhau los ntawm cov mesh thooj voos kheej kheej rau kev pom; Hloov chaw, nws ntws ncaj qha los ntawm lub taub hau thiab nthuav tawm mus rau ib qho kev siv conveyor -zoo li kis batter los ua pancake. Lub slurry concentration siv nyob rau hauv cov txheej txheem no kuj tseem muaj ntau dua li ntawm Hatschek txoj kev, feem ntau yog li ntawm 10% thiab 20%.
Qhov zoo ntawm Flow- ntawm Txheej Txheem yog qhov ua tau zoo. Cov cuab yeej muaj cov qauv yooj yim thiab xav tau kev nqis peev tsawg. Tsis tas li ntawd, cov txheej txheem tsim khoom suav nrog kev rov ua dej tsawg tsawg, ua rau cov dej tsis zoo ntawm cov dej khib nyiab thiab cov khoom pov tseg, ua rau nws muaj kev xaiv zoo rau ib puag ncig. Ntxiv mus, nws qhov kev ua tau zoo ntau lawm ua rau nws zoo tagnrho rau qhov loj - nplai ntau lawm, tso cai rau cov zis txhua hnub ntawm ntau txhiab square metres tau yooj yim.
Txawm li cas los xij, txoj kev slurry -casting method muaj nws cov kev txwv. Vim tias cov slurry yog siv ncaj qha yam tsis tau ua raws li cov kauj ruam pom zoo los ntawm cov xaim - lub log tsim txheej txheem, cov slabs tshwm sim tsis muaj qhov tiaj tus thiab qhov ntom ntom ua tiav los ntawm daim ntawv - txoj kev tsim. Yog li ntawd, cov slurry-casting txoj kev yog feem ntau yog siv los tsim nruab nrab- ntom boards (6–15 mm nyob rau hauv thickness), ua rau nws haum rau daim ntaub ntawv-xws li phab ntsa muab faib sab hauv thiab suspended ceilings- qhov twg qhov yuav tsum tau ceev tsis nruj me ntsis tseem ceeb.
Yuav xaiv li cas? Nws nyob ntawm koj "Saj"
Yuav kom ncaj ncees, ob qho ntawm cov txheej txheem no tsis zoo tshaj rau lwm tus; qhov tseem ceeb nyob hauv qhov koj xav tsim.
Rau kev tsim cov khoom lag luam nrog cov txheej txheem siab, xws li cov phab ntsa sab nrauv lossis cov ntaub thaiv phab ntsa, cov txheej txheem ntawm daim ntawv - feem ntau yog qhov kev xaiv zoo dua. Nws muab cov qib siab ceev, lub zog zoo, thiab kev siv fiber ntau zoo. Tsis tas li ntawd, nws yog resistant rau cua siab thiab cuam tshuam. Txawm li cas los xij, nws yuav tsum muaj kev nqis peev loj hauv cov cuab yeej siv thiab ua rau lub sijhawm tsim khoom ntev dua, yog li koj yuav tsum ua kom koj cov nyiaj tau los ntawm nws.
Rau tus nqi-kev ua tau zoo thiab kev tsim khoom siab, slurry casting txoj kev tuaj yeem yog qhov kev xaiv yog tias koj ua cov khoom nruab nrab- ntom ntom. Dhau li ntawm tus nqi qis ntawm cov cuab yeej siv, nws kuj muaj lub sijhawm kawm luv luv, tsim kom muaj ntau, tsis tshua tsim cov dej khib nyiab thiab ua kom yooj yim rau ib puag ncig.
