Thaum nws tsim nyog los thaiv lub tsev, ntau tus xaiv cov khoom siv polystyrene rau lub hom phiaj no. Txawm li cas los xij, ob peb tus neeg yuav khoom xav txog cov npe thiab hom kev sib txawv ntawm cov phiaj no. Feem ntau cov neeg siv khoom tsuas yog mus rau tom khw thiab nqa cov khoom muaj. Tab sis qhov no puas yog txoj kev coj ncaj ncees?
Yog tias koj paub tias qhov ntom ntawm polystyrene yog dab tsi, hom khoom no muaj dab tsi, cov kev xaiv rau nws siv, qhov no yuav pab txuag lub sijhawm thiab ua haujlwm kom tau raws li qhov ua tau.
Ntau yam khoom
Styrofoam muab faib ua pawg hauv qab no:
- nias (PS).
- Pressless (PSB).
- Extrusion (EPS).
- Autoclave.
- Autoclave extrusion.
Qhov sib txawv ntawm cov khoom siv tsuas yog nyob rau hauv ntau yam ntawm impurities ntxiv rau qhov muaj pes tsawg leeg. Nws tuaj yeem yog:
- Hluav taws kub retardant.
- YPlasticizer, thiab lwm yam.
Kev siv ntxivCheebtsam nyob rau hauv muaj pes tsawg leeg ntawm qhov sib tov ua rau muaj kev sib txawv ntawm lub cev thiab txhua yam yam ntxwv.
Cia peb paub nrog lub ntsiab, feem ntau hom nthuav dav polystyrene kom ntxaws ntxiv.
nias
Lub npe ntawm hom polystyrene hais txog txoj kev tsim cov rooj sib tham, uas feem ntau siv rau kev rwb thaiv tsev façade. Los ntawm nias, polystyrene tau txais, qhov ceev thiab lub zog ntawm cov uas yog tus cwj pwm los ntawm kev nce nqi. Nyob rau hauv cov nqe lus ntawm thermal rwb thaiv tsev, cov khoom no xyaum tsis txawv ntawm cov khoom uas tsis yog nias.
PS tsis yog siv dav, vim tias cov txheej txheem thev naus laus zis ntawm kev tsim cov khoom siv no nyuaj piv rau hom tau teev saum toj no, uas cuam tshuam ncaj qha rau tus nqi nce.
Pressless
Ib qho ntawm ntau hom, muaj ntau yam zoo thiab qhov sib txawv:
- Koj tuaj yeem paub cov khoom los ntawm cov cim ntawm cov pob khoom thiab cov ntawv luv PSB.
- Tus nqi qis.
- Tsev siv yooj yim kom tau txais cov khoom siv.
- High density polystyrene.
Dab tsi yog qhov ntom ntawm polystyrene? Koj tuaj yeem pom los ntawm cov lej tom qab sau ntawv. Qhov siab dua qhov ntsuas no, qhov ntau dua nws cov thickness, uas yog, qhov zoo ntawm cov khoom zoo dua. Expanded polystyrene ua npuas ncauj yog tus cwj pwm los ntawm qhov ntsuas qhov ntom ntom ntawm 15 txog 50 kg / m 3. Qhov thinnest yog rauKev rwb thaiv tsev ntawm tsev neeg, thiab cov ntawv ntawm polystyrene nrog qhov ntom ntawm 30 kg / m 3 twb tsim nyog rau kev rwb thaiv tsev thermal ntawm cov tsev nyob.
Cov khoom siv thiab nws cov yam ntxwv
Qhov ntsuas qhov ntom ntom txiav txim siab qhov kev sib kis thiab sib sau ntawm cov dej noo. Piv txwv li, tus lej qis txhais tau hais tias cov dej noo permeability ntawm polystyrene tsis tshaj 2% ntawm daim ntawv hnyav, tab sis qhov no tsuas yog ib qho kev kwv yees.
Txawm hais tias qhov ntom ntawm polystyrene nthuav dav, cov khoom siv tau zoo tsis cuam tshuam los ntawm kev ya raws, tab sis nws yog qhov zoo dua kom tsis txhob tso dej ncaj qha rau hauv dej, raws li cov xwm txheej uas tau muab tso rau hauv lub tsev lis dej num rau kev siv qhov no. khoom.
Hom thiab qhov ntom ntom ncaj qha cuam tshuam rau cov khoom siv hluav taws xob, qhov ntsuas siab dua, kev nyab xeeb ntawm polystyrene. Tsis txhob hnov qab txog kev ntsuas kev nyab xeeb thiab kev tiv thaiv hluav taws kub. Qhov no yog vim lub fact tias cov khoom yuav tsis hlawv, tab sis nws melts zoo kawg nkaus. Nyob rau tib lub sijhawm, cov pa roj carbon monoxide tau tso tawm rau hauv huab cua, uas tsis muaj qhov cuam tshuam zoo tshaj plaws rau kev noj qab haus huv ntawm tib neeg lub cev.
Polystyrene tsis kam rau deformation thiab txhua yam cuam tshuam
Cov cuab yeej tshwj xeeb uas ncaj qha nyob ntawm qhov ntom ntawm extruded polystyrene yog tiv taus deformation. Qhov siab dua lub zog thiab qhov ntsuas ntom, cov khoom muaj zog yog. Ntau tus neeg txhawj xeeb tias vim yog qhov kub thiab txias hloov los yog tus kheej cov yam ntxwv ntawm cov qauv, polystyrene yuav tawg lossis tawg. RauTxhawm rau txo qhov tshwm sim no, koj yuav tsum xaiv cov khoom siv nrog cov ntsuas lub zog siab.
Resistance to mechanical stress and the ultimate loads also depends on the indicator in question. Hauv qhov no, nws yuav tsum raug coj mus rau hauv tus account tias qhov zoo ntawm qhov ruaj khov ntawm cov khoom nyob ntawm seb tus naj npawb qhia qhov ceev npaum li cas.
Vim tias ib qho kev tsim kho yuav tsum muaj kev thauj khoom, tsis hais seb lawv puas yog lub sijhawm luv lossis ruaj khov, nws tsim nyog yuav cov khoom tsim nyog, suav nrog tus yam ntxwv ntawm lub tsev yav tom ntej.
Shape Resistant
Nov yog lwm qhov tshwj xeeb ntawm cov khoom uas tsim nyog them rau. Kev khaws cia ntev ntev ntawm cov laug cam nyob rau hauv qhov chaw cia khoom tsis raug tuaj yeem ua rau lawv qhov tsis zoo deformation lossis shrinkage.
Polystyrene yog cov khoom siv zoo nrog ntau qhov zoo. Nws cov hluav taws kub-insulating thiab suab nrov-tiv thaiv cov khoom yog qhov tshwj xeeb, uas tau piav qhia los ntawm kev sau cov voids ntawm cov granules nrog cov tshuaj tiv thaiv tshwj xeeb, feem ntau yog nplaim hluav taws. Lub thickness ntawm cov khoom tsis txawv ntawm cov tsoos polystyrene boards siv los ua tiav lub tsev facades.
Qhov ntau qhov ntom ntawm extruded polystyrene txiav txim siab muaj peev xwm siv nws hauv kev zoo nkauj sab nraum zoov. Xws li cov khoom yuav tsum ua tau raws li qhov yuav tsum tau ua rau elasticity ntawm qhov kub thiab txias kom cov hlau tsis deform los yog tawg. Raws li cov kev thov no, nws yog qhov zoo dua los thovthinner slabs uas ua tau raws li qhov yuav tsum tau muaj thermal rwb thaiv tsev.
Txoj kev sib cuam tshuam nrog ib puag ncig
Kev cuam tshuam nrog ib puag ncig nruj thiab noo noo tsis muaj qhov tseem ceeb, piv txwv li, rau kev rwb thaiv tsev ntawm lub hauv paus. Qhov xwm txheej ntawm cov av zoo li acidity lossis alkalinity muaj qhov cuam tshuam tsis zoo rau ntoo lossis lwm hom rwb thaiv tsev.
Nyob rau hauv rooj plaub no, qhov kev daws teeb meem zoo tshaj plaws yuav yog nteg extruded polystyrene boards. Tsis zoo li cov classic version, xws li nplooj ntawv xyaum tsis nqus noo noo thiab tsis cuam tshuam nrog cov tshuaj muaj pes tsawg leeg ntawm cov av.
Cov npog saum npoo yuav tsum tiv taus rau lub cev tseem ceeb: compression, khoov, torsion. Piv nrog cov polystyrene yooj yim, qhov ceev ntawm extruded polystyrene ua npuas ncauj muaj ib tug ntau elastic qauv, muaj peev xwm ua hauj lwm nyob rau hauv tag nrho cov lus qhia.
Txoj kev siv thiab kev teeb tsa ntawm polystyrene
Koj yuav tsum tsis txhob xav tias nrog kev nce hauv qhov zoo thiab qhov ntom ntawm cov khoom, cov yam ntxwv ntawm kev tso, kev thauj mus los thiab lwm yam haujlwm ntsig txog kev teeb tsa yuav hloov pauv. Raws li nrog kev tso pa ua npuas ncauj boards, nyob rau hauv cov txheej txheem ntawm xws li kev ua hauj lwm, ib tug pa saw los yog riam yog siv. Txhawm rau ua kom cov txheej txheem yooj yim, koj tuaj yeem yuav ib lub phaj ntawm qhov loj me los ntawm cov khoom muaj thiab cov qauv ntawm lub khw, nrog rau lawv qhov ntev. Qhov tseeb no twb tau kuaj xyuas hauv kev xyaum los ntawm cov neeg yuav khoom thiab cov kws ua haujlwm ua haujlwm nrog polystyrene, piv txwv li, thaum insulatingcov ru tsev uas muab tso rau hauv qhov tsis xis nyob, thiab cov qauv ru tsev muaj ob peb txoj kab nqes.
Khoom siv rau kev npaj cov cua sov hauv qab
Cov plag tsev cua sov tau siv ntau dua thiab tsis ntev los no. Txhawm rau kom lawv ua haujlwm li qub, nws yog ib qho tsim nyog yuav tsum ua kom muaj cua sov-insulating txheej. Rau cov hom phiaj no, extruded polystyrene rau underfloor cua sov nrog ib tug ceev ntawm 30-40 kg / m 3 yog zoo heev. Lub xub ntiag ntawm cov khoom siv no pab tiv thaiv kom tsis txhob poob ntawm cov cua sov uas tsim los ntawm cov cua sov.
Nws yog qhov tsim nyog hais tias qhov tuab ntawm cov khoom raug xaiv tus kheej. Yog tias pom zoo kom noj polystyrene nrog qhov ceev ntawm 30-40 kg / m 3, ces qhov no yuav tsum tau siv.
Thaum muab cov dej rhaub hauv pem teb hla cov chav uas tsis muaj cua sov, nws yog ib qho tseem ceeb kom paub tias qhov zoo tshaj plaws thickness ntawm rwb thaiv tsev rau pem teb sov yuav tsum yog tsawg kawg yog 100 hli. Qhov no kuj siv tau rau kev npaj ntawm lub hauv paus rau hauv av.
Cov lus pom zoo rau kev xaiv cov khoom
Thaum xaiv cov khoom siv rau facade lossis lub hauv paus rwb thaiv tsev, thov nco ntsoov tias qhov ua tau zoo ntawm kev ua haujlwm nyob ntawm:
- Polystyrene bulk ntom ntom.
- Muaj peev xwm ntawm cov khoom sib cuam tshuam nrog cov xwm txheej tsis zoo thiab ib puag ncig aggressive.
- Material quality.
- khoom nqi.
Tam sim no koj paub tias qhov ntom ntawm polystyrene yog dab tsi thiab koj tuaj yeem xaiv cov khoom uas zoo tshaj rau koj xav tau.
