Kev tsim kho thev naus laus zis niaj hnub tau nce mus ntev ua tsaug rau kev siv cov khoom siv polymeric. Lawv tsis tsuas yog pab txhawb txoj kev tsim kho, tab sis kuj txo qhov hnyav ntawm cov qauv. Tsis tas li ntawd, cov nqi cua sov thiab cov nqi tsim kho raug txo. Ib qho khoom siv polymeric yog polystyrene. Nws tuaj yeem pom hauv nplooj ntawv thiab granules. Nws yog tom kawg uas yog siv rau kev tsim cov pob zeb polystyrene. Cia peb saib cov khoom tseem ceeb ntawm cov khoom siv hauv tsev no, qhia txog nws qhov tsis zoo thiab, feem ntau, tau ntsib nrog cov kev tshuaj xyuas ntawm cov neeg uas twb tau ua lub tsev los ntawm nws.
Yuav ua li cas hu ua polystyrene pob zeb?
Polystyrene pob zeb yog cov khoom sib xyaw uas muaj cov pob zeb thiab polystyrene granules. Cov khoom siv no yog ib qho zoo tshaj plaws ntawm tag nrho cov uas twb muaj lawm nyob rau hauv peb lub sij hawm. Nws tuaj yeem siv ob qho tib si sib cais hauv daim ntawv ntawm cov blocks, thiab hauv kev tsim kho monolithic. Lwm qhov loj ntxiv ntawm polystyrene pob zeb yog qhov ua tau ntawm nwsua noj nyob rau ntawm qhov chaw tsim kho.
Kev tsim cov polystyrene pob zeb muaj nyob rau hauv gradual ntxiv ntawm polystyrene granules rau qhov sib tov. Cov tom kawg tuaj yeem ua tau ob qho tib si crushed thiab tag nrho, nyob rau hauv daim ntawv ntawm cov pob nrog ib txoj kab uas hla tsis tshaj 3 hli. Portland cement, Portland slag cement lossis gypsum tuaj yeem siv los ua cov ntawv khi. Aerated qhob, uas yog tsim los ntawm autoclave hardening, yog qhov txawv ntawm polystyrene pob zeb vim qhov tseeb tias tom kawg tau txais lub zog dhau sijhawm. Qhov no guarantees ib tug ntev kev pab cuam lub neej. Tab sis polystyrene pob zeb kuj muaj qhov tsis zoo. Thaum siv nws los tsim cov ntsiab lus monolithic hauv tsev, nws yuav tsum tau tos tsawg kawg 28 hnub rau kev pib ua haujlwm tom ntej.
Kev siv cov pob zeb polystyrene
Polystyrene pob zeb tau nrov heev hauv kev tsim kho txij li thaum nws pib. Vim muaj peev xwm npaj qhov sib tov ntawm lawv tus kheej, cov neeg loj heev pib tsim tsev los ntawm cov khoom sib xyaw no. Tib lub sijhawm, thev naus laus zis tsis tau ua raws li, thiab vim li ntawd, cov khoom tawg yooj yim tau txais. Vim qhov kev tsis saib xyuas no, polystyrene pob zeb tau txais kev tshuaj xyuas tsis zoo los ntawm cov neeg uas tsuas ua txhua yam tsis raug. Yog li cia peb rhuav qhov no me ntsis.
hom polystyrene pob zeb
Tam sim no nrog kev npaj tus kheej, siv ob hom polystyrene pob zeb: D350 thiab D1200. Thawj ntawm lawv yog siv los ua cua sov, thiab qhov thib ob - raws li cov khoom siv. Cov muaj pes tsawg leeg ntawm polystyrene pob zeb yog raws li nram no:
- rau polystyrene pob zeb qib D350Nws yuav tsum tau siv 300 kg ntawm cement M400 thiab 1, 1 cu. m polystyrene granules;
- rau D1200 polystyrene pob zeb, 300 kg ntawm M400 cement, 1, 1 cu. m ntawm polystyrene granules thiab 800 kg ntawm xuab zeb.
Raws li qhov tshwm sim, peb tau txais ob hom kev daws teeb meem, uas yuav luag zoo ib yam ntawm lub zog, tab sis thawj cov pob zeb tau txais nrog tsawg filling ntawm qhov khoob ntawm cov granules. Nws yog vim li no tias D350 yog siv rau rwb thaiv tsev, thiab D1200 rau phab ntsa.
Nws tseem tsim nyog sau cia tias txawm tias monolithic polystyrene pob zeb tsis tuaj yeem tiv taus cov khoom hnyav, thiab nws tsis tuaj yeem siv los tsim cov qauv thauj khoom.
Qhov tsis zoo ntawm polystyrene pob zeb
Ntawm tag nrho cov khoom uas polystyrene pob zeb muaj, qhov tsis zoo sawv tawm tsam cov keeb kwm yav dhau. Qhov teeb meem tseem ceeb yog cov granules. Thiab txawm hais tias polystyrene pob zeb yog cais raws li ib qho nyuaj rau combustible tshuaj, siab kub muaj qhov tsis zoo rau nws. Qhov tseeb yog tias polystyrene granules pib tawg, thiab qhov no txo qis zog.
Txo cov vapor permeability kuj yog qhov rho tawm. Piv nrog rau tib lub cellular pob zeb, polystyrene pob zeb muaj qhov ntsuas no 4 zaug qis dua. Cov cuab yeej no muaj qhov tsis zoo nyob rau hauv daim ntawv ntawm high humidity nyob rau hauv chav tsev. Kev quab yuam yog qhov yuav tsum tau siv yog tias siv polystyrene pob zeb.
Polystyrene pob zeb kuj muaj qhov tsis zoo nyob rau hauv daim ntawv ntawm cov dej muaj zog adsorption thiab tsis kam tiv thaiv kom khov. Qhov no cuam tshuam rau tag nrho cov kev pabcuam lub neej thiab nrog kev hloov pauv ntawm qhov kub thiab txias, lub hauv pausvaum.
Ib qho ntxiv hais txog tib neeg cov lus tsis txaus siab txog qhov loj me ntawm cov khoom vim kev siv cov granules. Qhov no feature yuav tsum tau daim ntawv thov ntawm ib tug tsawg kawg nkaus plaster txheej ntawm 15 cm. Raws li, tus nqi ntawm kev ua haujlwm nce.
Kev tshuaj xyuas ntawm polystyrene qhob tsev
Tsev ua los ntawm polystyrene pob zeb pib tsim los ntawm qhov zoo li ntawm cov khoom sib xyaw no. Cov koob meej tau loj hlob sai, thiab kev lag luam tau tshwm sim uas tsis tsuas yog tsim nws los tsim cov qauv monolithic, tab sis kuj tsim cov blocks. Lawv yog cov teeb, muaj zog thiab pheej yig. Tab sis cia peb soj ntsuam tiag tiag cov neeg hais.
Yog li, feem ntau muaj kev tshuaj xyuas txog tus nqi ntawm cov blocks thiab cov khoom sib tov. Nws tsis yog qhov xav tsis thoob tias lawv zoo, vim tias cov nyiaj khaws cia ntawm no yog qhov pom tseeb. Yog li, thaum piv nrog cellular pob zeb, polystyrene pob zeb tuaj yeem txo tus nqi txog li 20% nrog tib lub zog ua haujlwm.
Rau qhov kev tshuaj xyuas tsis zoo, feem ntau yog vim cov pej xeem tsis paub. Cov neeg xav tias polystyrene pob zeb tsev hlawv zoo li cov khoom sib tw qhuav. Qhov no tsis yog lawm. Qhov tseeb yog tias polystyrene granules tau muab ntim rau hauv lub plhaub pob zeb, thiab lawv tsuas tsis tuaj yeem ntes hluav taws. Txawm hais tias qhov hluav taws kub tshwm sim, cov khoom siv tsuas yog tawg, thiab vim li ntawd, cov blocks ua kom tawg yooj yim dua. Tab sis tsis muaj lus nug txog kev emissions thiab combustion khoom.
Polystyrene pob zeb tau txais kev tshuaj xyuas zoo vim yog kev kub ceev ntawm kev tsim tsev nrog nwsdaim ntawv thov. Blocks ntawm cov khoom siv no yog qhov loj, uas ua rau nws muaj peev xwm tsim cov phab ntsa sai. Kwv yees lub sij hawm tsim kho rau ib-zaj dab neeg tsev ntawm 120 sq. m yog ib thiab ib nrab rau ob lub hlis (nrog nchuav thiab tiv thaiv lub hauv paus).
Piav monolithic polystyrene pob zeb muaj qhov tsis zoo loj. Thawj yog ib tug loj shrinkage thaum lub sij hawm solidification. Feem ntau, cov neeg tsim khoom tsis suav rau nws. Qhov thib ob yog qhov yuav tsum tau thov ib txheej loj ntawm plaster. Qhov kev daws teeb meem no ua rau cov qauv hnyav dua thiab kim dua. Thib peb, nws yog qhov tsis xav kom thauj cov phab ntsa polystyrene pob zeb.
Yuav siv los tsis tau?
Ssuming up, peb tuaj yeem hais tias kev siv cov pob zeb polystyrene ua rau tag nrho cov nyiaj txiag txuag, thiab tib lub sijhawm, cov cua sov ntawm lub tsev txo qis. Nws raug nquahu kom siv cov khoom siv no ua cov khoom siv hluav taws xob ntxiv. Tab sis vim yog qhov tsis tshua muaj kev tiv thaiv rau cov khoom hnyav thiab zoo li qub, polystyrene pob zeb tsis pom zoo rau kev tsim cov khoom tseem ceeb ntawm lub tsev.
