Polystyrene: shortcomings. Lub tsev nyob ua polystyrene: xyuas

Niaj hnub nimno siv hom kev kawm tau ntev tshaj rau pem hauv ntej los ntawm kev siv ntawm polymeric cov ntaub ntawv. Lawv tsis tsuas yog pab txhawb cov kev siv cov txheej txheem, tab sis kuj yuav txo tau tus luj ntawm lub qauv. Ntxiv txog cov nqi ntawm cov cua kub thiab kev tsim kho nws tus kheej. Ib tug xws li polymeric khoom yog polystyrene. Nws muaj peev xwm yuav nrhiav tau nyob rau hauv cov ntawv txheeb thiab pellets. Nws twb kawg siv rau qhov siv thiab ua polystyrene. Cia peb xav txog qhov yooj yim thaj chaw ntawm lub tsev cov ntaub ntawv uas, highlight qhov tsis zoo sib nrauj thiab feem ntau tau ntsib nrog cov neeg uas twb ua ib lub tsev tawm ntawm nws.

Yuav ua li cas yog hu ua polystyrene qhob?

Polystyrene - qhov no yog ib tug puas khoom, uas muaj kev ua vaj tse thiab polystyrene pellets. Qhov no cov ntaub ntawv uas yog ib tug ntawm qhov zoo tshaj ntawm tag nrho cov uas twb muaj lawm nyob rau hauv peb lub sij hawm. Nws yuav siv tau ob qho tib si raws li nyias muaj nyias ib lub ntsiab nyob rau hauv daim ntawv ntawm cov blocks thiab nyob monolithic siv. Lwm heev loj kom zoo dua polystyrene yog tseem ua noj ua haus rau cov kev siv ntawm qhov chaw.

Qhuav ntawm polystyrene yog maj ntxiv mus rau ib tug sib tov ntawm polystyrene pellets. Cov yav tas yuav tsum yog crushed los yog tag nrho, nyob rau hauv daim ntawv ntawm cov hlaws dai muaj ib lub cheeb ntawm tsis ntau tshaj 3 hli. Cov phau ntawv tej zaum yuav siv Portland maas, slag los yog gypsum. Aerated qhob, uas yog ua nrog rau kev siv autoclaved, yog heev txawv los ntawm polystyrene vim lub fact tias cov tom kawg yog nkag mus rau hauv lub dag lub zog nrog lub sij hawm. Qhov no saib kuas ib tug ntev npaum li cas lub neej. Tab sis nws kuj muaj disadvantages polystyrene. Yog hais tias koj siv nws los ua ib tug monolithic ntsiab yuav tsum tau mus tos tsawg kawg 28 hnub rau lub caij pib cov nram qab no tej hauj lwm.

Kev siv cov polystyrene

Polystyrene txij li thaum nws inception tam sim ntawd los ua heev nrov nyob rau hauv kev tsim kho. Vim tau npaj ib tug sib tov ntawm lawv tus kheej, cov neeg en masse pib ua vaj tse tawm ntawm no puas mater. Thaum zoo li no technology yog tsis adhered, thiab whereby ib tug lub cev tsis kho cov ntaub ntawv uas. Vim li no cov teeb meem polystyrene tau txais tsis zoo xyuas los ntawm cov neeg uas cia li ua txhua yam tsis ncaj ncees lawm. Yog li ntawd, cia peb nrog no.

Lub ntsiab yam ntawm polystyrene

Tam sim no nyob rau hauv nws tus kheej-kev npaj yog siv ob hom polystyrene: D350 thiab D1200. Cov Thawj zaug ntawm lawv yog siv raws li ib tug rhaub, thiab lub thib ob - raws li ib tug kev tsim kho cov ntaub ntawv uas. Muaj pes tsawg leeg ntawm polystyrene nram qab no:

• kom tau polystyrene D350 hom xav siv 300 kg ntawm MAAs M400 thiab 1.1 cc. m polystyrene hlaws dai;
• D1200 cim rau polystyrene yog siv 300 kg ntawm MAAs M400, 1.1 cu. m polystyrene pellets thiab 800 kg ntawm cov xuab zeb.

Raws li ib tug tshwm sim, peb tau ob hom ntawm kev daws, uas los ntawm nws lub zog yog yuav luag identical, tab sis tus thawj qhob tau nrog me me sau qhov khoob ntawm cov granules. Nws yog vim li no D350 yog siv rau thermal rwb thaiv tsev, thiab D1200 - rau qhov kev siv ntawm cov phab ntsa.

Nws tseem yog nqi sau cia hais tias txawm tias ib tug monolithic polystyrene qhob yuav tsis tau withstand hnyav loads, thiab siv nws los tsim ib tug load-tau cov kabmob lug tsis tau.

disadvantages ntawm polystyrene

Ntawm tag nrho cov yam ntxwv uas muaj styrofoam, raug tshwj xeeb tshaj yog sawv tawm. Lub ntsiab teeb meem yog cov pellets. Txawm tias raug xa mus rau raws li polystyrene nyuaj flammable tshuaj, siab kub muaj ib tug tsis ntxim rau nws. Lub fact tias cov polystyrene granules pib mus ua txhaum down, thiab nws ho thiaj li muaj zog.

Nws txo qis dej vapor permeability kuj yog ib tug rho tawm. Piv rau tus tib cellular ua vaj tse, polystyrene muaj qhov ntsuas no yog 4 lub sij hawm tsawg dua. Qhov no tej khoom vaj tse muaj ib tug tsis zoo feem nyob rau hauv daim ntawv ntawm cov pwm nyob rau hauv lub chav tsev. Yuam kom muab tso rau lub hood yog yuav tsum tau, yog hais tias siv styrofoam.

Ntau polystyrene muaj disadvantages nyob rau hauv daim ntawv ntawm cov muaj zog dej adsorption thiab tsawg kuj mus khov. Qhov no muaj feem xyuam rau lub zuag qhia tag nrho cov kev pab lub neej thiab ceev ceev kub hloov, lub hauv paus yog kev puas tsuaj.

Koj muaj peev xwm ntxiv hais txog cov kev tsis txaus siab ntawm cov neeg nyob rau hauv ntau dua shrinkage ntawm cov ntaub ntawv uas vim kev siv ntawm granules. Qhov no feature yuav tsum tau stucco overlay 15 cm tsawg kawg nkaus txaj. Raws li, qhov nce nqi ntawm tej hauj lwm.

Xyuas ntawm lub tsev ntawm polystyrene

Lub tsev nyob ua polystyrene tau ua los ntawm cov tsos ntawm tus qhab khoom. Chaw loj hlob sai heev, thiab muaj ntau lawm, uas tsis tsuas yog tso nws los ua ib tug monolithic lug, tab sis kuj yuav ua kom cov blocks. Lawv yog cov khaub-ncaws nyias, khov kho thiab pheej yig. Tab sis cia tus yeej txheeb xyuas dab neeg yog hais tias.

Yog li ntawd, lub feem ntau heev cov lus teb hais txog cov nqi ntawm cov chav nyob thiab mixtures. Tsis ceeb, lawv yog cov zoo, vim hais tias cov nyiaj khaws tseg yog cuab kev. Yog li, thaum piv nrog cellular ua vaj tse, lub polystyrene tso cai rau kom txo nqi los mus txog rau 20% ntawm lub qub zog.

Raws li rau qhov phem xyuas, feem ntau ntawm lawv vim cov tsis muaj kev ras paub txog cov pej xeem. Cov neeg xav hais tias hlawv lub tsev nyob ntawm polystyrene, raws li qhuav qhov yuam kev. Qhov no yog kiag li tsis ncaj ncees lawm. Lub fact tias cov polystyrene pellets yog muab ntim rau hauv ib lub pob zeb plhaub, thiab kom lawv cia li yuav tsis txais taws zoo. Txawm hais tias ib tug tua hluav taws tshwm sim, cov khoom yog tsuas rhuav tshem, thiab raws li ib tug tshwm sim blocks ua ntau taus. Cuaj kaum, tsis muaj emissions thiab combustion khoom yuav tsis txawm taug kev thiab tham.

Polystyrene tau txais zoo xyuas txawm nyob rau hauv cov nuj nqis ntawm high-ceev kev siv ntawm tsev nrog nws siv. Cov blocks ntawm no cov ntaub ntawv uas cov loj loj nyob rau hauv loj, uas ua rau nws ua tau rau sai sai tau lub phab ntsa. Approximate hnub ntawm kev tsim kho ib-zaj dabneeg lub tsev ntawm 120 square meters. m yog ib tug thiab ib tug ib nrab rau ob lub hlis (nrog sau thiab hauv ntawm lub hauv paus).

Sau nrog polystyrene shortcomings nrum yog zoo kawg thiab. Tus thawj - ib tug siab shrinkage thaum lub sij hawm solidification. Heev feem ntau builders tsis suav rau nws. Qhov thib ob - yog qhov yuav tsum tau mus thov ib tug tuab txheej ntawm plaster. Qhov kev txiav txim ua rau cov qauv cev ntas thiab kim kim. Qhov thib peb - cov phab ntsa hauv polystyrene undesirable load.

Siv los yog tsis?

Summing li, peb yuav hais tias cov kev siv ntawm polystyrene tau nyob rau hauv ib tug tag nrho saving ntawm nyiaj txiag, thiab nyob rau tib lub sij hawm thiaj li lub tshav kub tsis tau kev hauv lub tsev. Thov active khoom nyob rau hauv daim ntawv ntawm ib tug ntxiv insulator yog pom zoo. Tab sis vim hais tias ntawm qhov uas tsis muaj nqi ntawm kuj mus dynamic thiab zoo li qub loads polystyrene yuav tsum tsis txhob siv rau qhov siv thiab tseem ceeb heev Cheebtsam ntawm lub tsev.
