Ntau tus neeg paub tias muaj cov khoom siv hauv tsev xws li cov av nplaum nthuav dav. Qhov no yog ib qho kev paub. Tab sis ob peb tus neeg tuaj yeem muab cov lus teb kom tiav rau cov lus nug ntawm nws yog dab tsi, nws muaj dab tsi, nws tsim thiab siv qhov twg. Wb sim kaw qhov khoob no.
Dab tsi yog av nplaum nthuav dav
Cov av nplaum nthuav dav yog cov khoom ntxeem tau uas ua rau hauv daim ntawv ntawm pob zeb lossis pob zeb crushed. Nws ntau lawm yog raws li nyob rau hauv firing nyob rau hauv tshwj xeeb kilns ntawm ib tug kub ntawm txog 1200 ° C tshwj xeeb av nplaum pob zeb ntawm yooj yim melting. Ua tsaug rau kev tua, cov qauv av nplaum tau txais cov qauv zoo nkauj nrog lub plhaub tawv tawv.
Cov qauv ntawm cov khoom no txiav txim siab ntau haiv neeg ntawm nws daim ntawv thov. Cov khoom siv no yog siv ob qho tib si hauv kev tsim kho thiab thaum cog cov nroj tsuag. Cov khoom tshwj xeeb ntawm cov av nplaum nthuav dav suav nrog dej thiab Frost tsis kam, zoo heev suab nrov-absorbing thiab kub-insulating tsis. Cov khoom siv yog xyaum tsis raug rau cov txheej txheem ntawm lwj thiab decomposition, tsis nyiam kab thiab nas. Tsis tas li ntawd, nws yog ruaj thiab fireproof, Frost thiab acid resistant, hnav thiab ruaj, environmentally friendly thiab economical. Ua tsaug rau cov khoom zoo no, cov av nplaum nthuav dav tau siv dav hauv kev tsim kho thiab lwm yam kev lag luam.
Ncua av nplaum ua lub tshav kub rwb thaiv tsev
Lub peev xwm ntawm cov av nplaum nthuav dav los ua cov cua sov insulator nyob ntawm qhov loj ntawm cov granules, nws lub zog thiab qhov ntom ntom. Raws li qhov loj ntawm cov granules, nthuav av nplaum feem ntawm 5-10, 10-20 thiab 20-40 mm yog txawv. Txhua feem tso cai 5% ntawm granules ntawm qhov sib txawv. Raws li qhov ceev ntawm cov av nplaum nthuav dav, 10 qib tau txhais, xws li ntawm 250 mus rau 800. Cov lej no qhia cov lej ntawm kilograms hauv ib lub cubic meter ntawm cov khoom. Qhov qis dua qhov ntom, qhov zoo dua cov khoom ntawm cov av nplaum nthuav dav raws li lub tshav kub insulator. Nthuav av nplaum ntawm feem loj yog ruaj dua. Nws yog qhov tsim nyog, piv txwv li, ua kom sov hauv pem teb hauv chav da dej, thiab thermal rwb thaiv tsev ntawm lub tsev pheeb suab kuj tuaj yeem ua tiav nrog ib feem zoo.
Kev nthuav av nplaum ntau lawm
Tsuas yog cov av nplaum pob zeb tsim nyog rau kev tsim cov av nplaum nthuav dav. Qhov tsim nyog tshaj plaws yog montmorillonite thiab hydromicaceous av nplaum uas muaj tsawg dua 30% quartz. Lub ntsiab lus ntawm cov av nplaum nthuav dav yog qhov ua ntej ntawm cov av nplaum nyoos, uas muab cov granules nyoos ntawm ib qho me me, tua lawv hauv qhov tshwj xeeb nruas qhov cub kom tau txais cov qauv tshwj xeeb thiab maj mam txias.
Muaj ntau lub thev naus laus zis rau kev kho ua ntej ntawm cov khoom siv av nplaum. Qhov no yog kev ua kom qhuav, yas, hmoov-yas, zoo li ntub dej, los yog plam. Thawj (qhuav) thev naus laus zis - qhov yooj yim tshaj plaws - muab rau ntau theem crushing ntawm cov av nplaum pob zeb nrog kev tshuaj xyuas cov feem tsim nyog rauua ntxiv. Qhov thib ob, feem ntau - yas - muaj nyob rau hauv kneading nyoos av nplaum nrog ib tug av nplaum tov khoom, molding cylindrical granules thiab ziab lawv. Cov hmoov-yas thev naus laus zis txawv ntawm yav dhau los tsuas yog nyob rau hauv uas cov ntaub ntawv raw tau hloov mus ua hmoov ua ntej kneading. Thaum kawg, nrog cov cuab yeej ntub dej los yog plam, lub npe hu ua plam nrog cov dej noo ntawm li 50 feem pua yog thawj zaug tau los ntawm cov khoom siv raw thiab dej siv cov av nplaum mashers, uas yog tom qab ntawd muab tso rau hauv qhov cub, uas muaj cov kab hlau rhuav tshem cov saw hlau. Cov tom kawg yog rhuab thiab rhuav cov plam mus rau hauv cov khoom, uas tau raug rho tawm haujlwm.
Lub tshuab hluav taws xob nyob rau hauv daim ntawv ntawm lub nruas tua yog ntsia ntawm me ntsis inclination. Thawj cov khoom nyob rau hauv daim ntawv ntawm cov av nplaum granules yog poured rau hauv nws lub Upper kawg thiab maj mam dov mus rau lub burning nozzle. Nyob rau hauv qhov cuam tshuam ntawm cov pa roj kub thiab muaj zog thermal shock, thaum ntog ntawm cov roj kub ntawm lub nozzle (nrog rau qhov kub ntawm li 1200 degrees), av nplaum boils thiab swells, melting nws txheej txheej.
Tag nrho cov txheej txheem tua tsis pub dhau 45 feeb, ua kom paub txog lub teeb yuag thiab ruaj khov av nplaum nplaum. Lwm cov feem ntawm nthuav av nplaum ntau lawm (suab zeb los yog xuab zeb) yog tau los ntawm crushing no gravel. Cov khoom lag luam zoo tuaj yeem tau txais los ntawm cov thev naus laus zis raws li kev siv ob thiab peb-nruas rauv, uas cov nruas tig ntawm qhov sib txawv, tsim kom pom hom kev kho cua sov ntawm cov khoom siv raw.
theem kawg ntawm kev nthuav dav av nplaum yog txias rau ntau theem nrog maj mamlos ntawm kev txo qhov kub, ua ntej hauv qhov cub nws tus kheej, tom qab ntawd hauv lub nruas thiab txheej txias, thiab thaum kawg hauv airslides.
siv cov av nplaum nyob qhov twg
Qhov no tsuas yog ib daim ntawv teev npe me me xwb:
- thermal rwb thaiv tsev ntawm lub ru tsev, qab nthab thiab cov plag tsev;
- soundproofing ntawm qab nthab thiab cov plag tsev;
- tsim txoj kab nqes ntawm cov nyom nyom;- tsim cov pob zeb sib sib zog nqus, nthuav cov av nplaum pob zeb;- thermal rwb thaiv tsev ntawm cov hauv paus thiab av;- kua hauv kev tsim kho;- cog ntoo (hydroponics).
Xa daim ntawv nthuav dav av nplaum
Kev xa khoom nthuav av nplaum rau hauv lub hnab lossis hauv ntau ntawm cov tsheb thauj khoom pov tseg. Cov khoom ntim tau yooj yim dua. Nws yog qhov yooj yim dua los coj mus rau hauv tus account (20 lub hnab ua ib lub voos xwmfab ntawm cov av nplaum nthuav dav), tshem tawm, khaws cia, thiab thauj mus rau qhov chaw ua haujlwm. Loose expanded av nplaum yog pheej yig dua, tab sis nws ua rau muaj teeb meem ntau dua. Yog li ntawd, nws yog qhov zoo dua los siv cov av nplaum nthuav dav hauv hnab.
rwb thaiv tsev hauv pem teb nrog nthuav av nplaum
Ib feem tseem ceeb ntawm lub zog cua sov tawm hauv tsev mus rau hauv pem teb. Txhawm rau kom tsis txhob muaj qhov poob, hauv pem teb yog insulated. Qhov no yog ib qho tseem ceeb tshwj xeeb tshaj yog nyob rau hauv rooj plaub uas lub hauv pem teb yog ua los ntawm pob zeb. Ntawm ntau cov ntaub ntawv thermal rwb thaiv tsev muaj nyob rau hauv kev ua lag luam, nthuav av nplaum yog qhov pheej yig tshaj plaws. Daim ntawv thov ntawm cov khoom siv no (raws li lub rhaub) yog kab tias feem ntau siv hauv kev tsim kho. Thiab qhov no tsis yog qhov xav tsis thoob. Tom qab tag nrho, ib txheej ntawm cov av nplaum nthuav dav 10 cm tuab sib haum rau hauv nws cov khoom insulating rau ib meter tuab brickwork los yog 25 cm tuab ntoo. nthuav av nplaum yog siv rau hauv pem teb (rau nws.rwb thaiv tsev) los ntawm txoj kev qhuav (bulk method) los yog sau nrog nthuav av nplaum pob zeb screed. Cov txheej txheem ntawm kev ua kom sov yog qhov yooj yim heev, nws tuaj yeem ua tiav ntawm koj tus kheej. Nws suav nrog cov kauj ruam hauv qab no:
- cim qib ntawm cov av nplaum nthuav dav (kom zoo dua rwb thaiv tsev, txheej yuav tsum yog tsawg kawg 10 cm);
- ua cov dej tsis muaj dej (muaj zog polyethylene zaj duab xis);
- teeb tsa beacons kom tau lub tiaj tiaj;
- filling thiab compaction ntawm rwb thaiv tsev txheej;
- leveling nto nrog txoj cai;
- pob ib txheej ntawm cov cement-sand screed tshaj nthuav av nplaum.
Koj tuaj yeem pib siv cov plag tsev tsuas yog tom qab cov screed tau qhuav. Kev nrawm ntawm cov rwb thaiv tsev hauv pem teb tuaj yeem ua tiav siv txoj kev qhuav, thaum Knauf cov plag tsev tau muab tso rau hauv cov txheej txheem ntawm cov av nplaum nthuav dav. Lawv tuaj yeem siv tau tam sim ntawd tom qab sib dhos hauv pem teb los ntawm cov khoom txuas nrog PVA kua nplaum thiab tus kheej tapping screws.
