Muaj tseeb koj tau hnov txog cov khoom xws li polystyrene pob zeb. Ib lub npe hloov dua tshiab yog cov pob zeb sov. Peb yuav kawm ntxiv txog ob qho tib si nws muaj pes tsawg leeg, yam ntxwv, thiab daim ntawv thov, qhov zoo thiab qhov tsis zoo.
Sov pob zeb - yog dab tsi?
Sov (polystyrene pob zeb) pob zeb yog ib hom pob zeb sib xyaw nrog nthuav dav polystyrene granules uas txhim kho lub zog thiab thermal yam ntxwv ntawm cov khoom. Kuj tseem hu ua cov pob zeb sov yog ib hom ntawm cov khoom siv no uas muaj ntau cov khoom siv ntxiv uas tsis tso cai rau nws ua kom tawv tawv ntawm qhov kub qis qis los ntawm cov txheej txheem tsim khoom kom txog rau thaum daim ntawv thov heev.
Polystyrene qhob Cheebtsam muab tsis xav tau ntxiv rwb thaiv tsev ntawm chav. Cov muaj pes tsawg leeg ntawm cov qhob sov yog raws li nram no:
- Portland cement.
- dej.
- nthuav polystyrene (nthuav polystyrene, tus nqi uas yog tus nqi qis) hauv granules.
- Ntoo-saponified resin (air-entraining inclusion).
Tus nqi ntawm nthuav polystyrene txawv ntawm 900-1200 rubles rau 5 m 2 (ib txheej ntawm ob peb daim phiaj). Vim li cas thiaj tsis raug nqi suav nrog hauv pob zeb.
khoom siv
Tseeb sivsov pob zeb raws li nram no:
- Kev tsim vaj tsev nyob.
- monolithic vaj tsev tsim.
- Suab thiab cua sov ntawm cov plag tsev, qab nthab, phab ntsa thiab slabs.
- rwb thaiv tsev ntawm cov tsev thiab cov qauv.
Tsis tas li, cov khoom siv tau zoo siv los ua cov tshuaj tsis zoo rau:
-
Filling spaces:
- Kev tsim laj kab, thaiv.
- Tau qhov kab noj hniav sab hauv ntawm grillage.
- Tau lub tsev lub hnab ntawv nyob rau hauv daim ntawv ntawm lub tsev phab ntsa.
-
Kev txo qis rau txhua tus qauv:
- Thaum tsim ua luam dej.
- Thaum npaj cov plag tsev hauv tsev.
- Thaum siv los ua cov khoom thauj khoom ntawm cov corrugated board, nws tau sau los ntawm sab hauv nrog polystyrene pob zeb.
- Nyob rau hauv rooj plaub uas hygroscopicity ntawm cov khoom yuav tsum tau (tsis txhob tawg nyob rau hauv lub siab ntawm linear loads).
- Thaum nws tsim nyog yuav tsum tau nruab rau hauv pem teb txoj kab nqes hauv cov qauv ntab, uas yuav pab txo qis kev thauj khoom ntawm tag nrho cov qauv.
Qhov kev siv dav tshaj plaws hauv kev tsim kho yog cov pob zeb ua pob zeb nrog qhov ntom ntawm 200-600 kg / m 3. Cov peev txheej ntawm lawv siv ncaj qha nyob ntawm tus yam ntxwv no:
- 450-600 - enclosing and load-bearing structures in low-rise buildings.
- 400-600 - sab nraud kabmob phab ntsa hauv kev tsim qis qis.
- 300-350 - kab hlau rhuav phab ntsa.
- 200-300 - tsuas yog siv los ua cov khoom siv insulating.
Cov txiaj ntsigkhoom
Cia sau cov txiaj ntsig tseem ceeb ntawm cov pob zeb sov:
- Lub suab tsis zoo thiab cov rwb thaiv tsev kub ntawm cov khoom yog ob peb zaug siab dua li cov pob zeb zoo tib yam. Qhov no tso cai rau koj tsis txhob cuam tshuam nrog kev rwb thaiv tsev ntxiv nrog cov ntxhia wool, ua npuas ncauj iav, ua npuas ncauj yas, thiab lwm yam.
- Sov pob zeb yog cov khoom siv nyiaj txiag heev vim tias nws ua haujlwm ntau lub sijhawm.
- Polystyrene pob zeb muaj ntau zaus tsawg dua li cov pob zeb zoo tib yam, uas yooj yim rau kev thauj khoom / tshem tawm thiab kev thauj mus los.
- Lub nra hnyav ntawm cov qauv ua vaj tse sov kuj tseem tsawg dua tus qauv, uas txo tus nqi ntawm kev tsim lub hauv paus.
- Qhov yooj yim ntawm kev ua cov khoom tuaj yeem muab piv nrog ntoo: nws yooj yim rau pom, xyaum, rauj rauj rau hauv nws.
- Cov khoom siv zoo ib puag ncig - muaj dej, pob zeb thiab polystyrene ua npuas ncauj.
- Kev nqus dej ntawm cov khoom yog qhov nruab nrab ntawm cov pob zeb ua npuas ncauj thiab cov pob zeb zoo tib yam.
- Los ntawm kab lus dhau los los ntawm lwm qhov kom zoo dua - siab Frost resistance.
- Low vapor permeability.
Qhov tsis zoo ntawm polystyrene pob zeb
Cov khoom siv kuj muaj ntau qhov tsis zoo:
- Kho cov ntaub ntawv hauv nws cov tuab tuav xoob.
- Cov khoom siv tsawg tsawg cuam tshuam rau qhov zoo ntawm kev teeb tsa lub qhov rais thiab qhov rooj - dhau sijhawm, lawv pib xoob.
- Cov khoom muaj txiaj ntsig ntawm cov khoom yog nyob ntawm qhov zoo ntawm nws lub hauv paus - pob zeb.
- Plaster tsis ua kom zoo txaus kom sov pob zeb, ua rau saum npooyuav tsum tau npaj ntxiv ua ntej plastering.
- Hais txog kev shrinkage, nws yog peb zaug ua ntej ntawm ob qho tib si ua npuas ncauj thiab aerated qhob - 1 mm / m.
- Blocks ntawm cov khoom tsis suav tias yog combustible, tab sis lawv kuj tsis hluav taws kub. Qhov no txhais tau hais tias nyob rau hauv qhov kub ntawm qhov kub, qhov nthuav dav polystyrene granules tawg, uas ntxiv ua rau poob ntawm thermal rwb thaiv tsev zoo.
Peb tau txheeb xyuas cov yam ntxwv tseem ceeb ntawm ib qho ntawm cov khoom siv niaj hnub no - cov pob zeb sov so nrog cov khoom sib ntxiv ntawm polystyrene ua npuas ncauj. Zoo li txhua qhov sib xyaw ua ke, nws tau txais txiaj ntsig nrog ob qho tib si ntawm qhov zoo thiab qhov tsis zoo.
