Polymer concrete: composition, types, features, application technology thiab kev txheeb xyuas

Polymer pob zeb yog ib yam khoom siv tshwj xeeb uas yog siv los ua ib qho khoom ua ke, nrog rau kev hloov cov txiv qaub cement. Tej zaum, lub polymer yog siv los ntxiv rau Portland xis mas. Nws yog ib qho khoom plig thoob ntiaj teb uas ntev tau los ntawm cov khoom sib tov sib xyaw nrog cov hluavtaws lossis cov cim ntuj tsim. Cov khoom siv no tau siv ntau lub lag luam, tab sis feem ntau yog nyob hauv kev tsim kho.

Hom

Hauv kev tsim kho, peb hom polymer pob zeb siv. Tsis tas li ntawd, peb yuav ua tib zoo saib lawv cov cuab yeej tsim tawm, cov kev cai thiab cov kev cog lus kom muaj lub tswv yim dav hlau ntawm cov pob zeb thiab cov kev hloov kho.

Polymeric compositions rau kev ua vaj tse (polymer modified qhob)

Xws li ntau hom kev lag luam yog tsim los ntawm Portland xis mas nrog ib daim qauv hloov polymer, xws li acrylic, polyvinyl acetate thiab ethylene vinyl acetate. Nws muaj zoo adhesion, siab khoov siab thiab tsis muaj permeability.

Acrylic polymer hloov ua vaj tse yog tsi ntsej muag los ntawm ib tsos mob, uas yog vim li cas nws yog nyob rau hauv zoo kawg thov ntawm builders thiab architects. Nws cov kev hloov kho yog zoo li cov tshuaj cement variation. Tus nqi ntawm polymer feem ntau yog los ntawm 10 mus rau 20%. Qhob hloov kho hauv txoj kev no muaj qis dua ntawm permeability thiab muaj ntau dua li cov ntshiab cement. Txawm li cas los, nws cov qauv kev ntseeg yeej tseem yog nyob ntawm tus neeg saib xyuas kev ruaj ntseg ntawm Portland xis mas.

Qhov degradation ntawm pob zeb yuav siv sij hawm ntev dua yog tias nws muaj qhov siab ceev thiab thaj tsam me me. Ib txhim kho txhim kho hauv cov tshuaj tiv thaiv ntawm cov khoom siv polymer hloov los rau Portland xis mas yog ua tau rau hauv nruab nrab cov kua qaub.

Polymer impregnated ua vaj tse

Polymeric impregnation rau cov pob zeb yog feem ntau yog ua los ntawm kev siv cov ntsiab lus tsawg tsawg rau hauv Portland cement, raws li hluav taws xob lossis thermal catalytic polymerization. Qhov hloov elasticity ntawm hom pob zeb no yog 50-100% siab tshaj qhov ntawm cov pob zeb ua ke.

Txawm li cas los xij, tus qauv polymer yog 10% loj dua li ntawm cov pob zeb ua ke. Vim yog cov yam ntxwv zoo, ntawm cov kev siv ntau yam ntawm cov khoom siv polymer, peb tuaj yeem hais cov lus qhia ntau ntxiv:

• Decks;
• Txuas hniav;
• Kav;
• Pem teb vuas;
• Lub tsev laminate.

Kev siv tshuab ntawm lub implantation txheej txheem yuav ziab lub pob zeb kom tshem tawm ntawm noo los ntawm nws cov av, siv monomers nyob rau hauv ib txheej xuab zeb, ces polymerizing cov monomers siv heat flow. Txawm li cas los, cov pob zeb siv tau muaj cov dej tsis zoo, nqus dej, txhaws thiab ua raws li txoj cai, siab zog. Tsis tas li ntawd, los txhim kho lub coj kuj, kuj kom txias thiab dej, yog siv polymeric coatings rau ua vaj tse, cib, pob zeb, plag tsev, thiab lwm yam

Polymer pob zeb ua kev

Nws tsis muaj ib yam dabtsi ua nrog rau lub rooj sib tham li niaj zaus. Nws yog tsim los ntawm cov pob zeb nrog lub pob ntawv polymeric uas tsis muaj dej. Polystyrene, acrylic thiab epoxy resins yog monomers uas dav siv nyob rau hauv lub chaw ua khoom ntawm no hom ntawm qhob. Sulfur tseem suav hais tias yog ib qho polymer. Serobeton yog siv rau cov vaj tse uas yuav tsum tau muaj kev ntseeg siab mus rau qhov nruab nrab ntawm acidic. Cov thermoplastic polymers, tab sis feem ntau thermosetting resins, yog siv los ua lub ntsiab ntawm cov tshuaj polymer vim lawv siab thermal stability thiab ua hauj rau ntau hom tshuaj.

Polymer pob zeb muaj cov aggregates uas muaj silica, quartz, granite, limestone thiab lwm yam khoom zoo. Chav tsev yuav tsum yog qhov zoo, dawb los ntawm hmoov av, khib nyiab thiab ntau heev noo noo. Yog tsis ua raws li cov lus teev tseg no yuav txo tau cov nyiaj ntawm daim ntawv cog lus ntawm cov ntawv pov thawj polymer thiab cov khoom sib sau ua ke.

Ntaus ntawm cov pob zeb polymer

Cov khoom siv niaj hnub no sib txawv ntawm nws cov neeg ua ntej. Nws muaj cov yeeb yam nram qab no:

• Siab ua rau cov tshuaj lom neeg thiab tshuaj lom.
• Piv nrog cov cement-pob zeb khoom, nws muaj qis pawg.
• Kev nqus tau zoo heev ntawm lub suab nrov thiab kev sib tw.
• Zoo huab cua thiab tsis kam mus rau ultraviolet hluav taws xob.
• Kev nqus dej.
• Tau txiav siv cov hnyiab thiab grinders.
• Yuav muab siv ua pob zeb txawb los yog hauv av los ua ib txoj hauv kev.
• Kwv yees li ntawm 4 npaug tshaj zog dua pob zeb cement.
• Cov hluav taws xob kom zoo thiab muaj kev ruaj ntseg.
• Ultra-smooth tiav, uas muaj txhawb rau ib qho kev khiav hydraulic.

Siv

Polymer concrete yuav siv tau rau kev tsim kho tshiab los yog kho cov ntaub ntawv qub. Nws adhesion zog cia rov qab los ntawm ob qho tib si polymer thiab cov pob zeb ua ke ntawm cov cement puag. Tsawg permeability thiab corrosion tiv thaiv tau siv hauv pas dej da dej, dej ntxuav dej, kua dej, kua roj electrolytic thiab lwm cov khoom muaj kua los yog tshuaj lom neeg. Nws yog tsim rau kev tsim kho thiab kev kho kom rov zoo ntawm cov qhov dej, ua tsaug rau nws lub peev xwm los tiv thaiv cov kab mob lom thiab corrosive dej phwj tuaj thiab cov kab mob uas pom muaj nyob hauv cov kav dej.

Tsis zoo li cov khoom siv hauv kev ua vaj tse, nws tsis tas yuav lo los yog kev tiv thaiv ntawm PVC kev tiv thaiv. Koj tuaj yeem pom kev siv cov pob zeb ntawm cov pob zeb ntawm txoj kev ntawm lub nroog. Nws yog siv hauv kev tsim kho ntawm txoj kev ntawm txoj kev, kev taug kev, cov dej xau, cov dej txhaws. Tsis tas li ntawd nyob rau hauv txoj kev ib tug polymer lo rau pob zeb ua yog ntxiv rau cov asphalt nyob rau hauv kev tsim kho ntawm sab nraum zoov qhov chaw, runways thiab lwm cov chaw, uas yog nyob rau hauv lub qhib huab cua thiab yog lossi raug mus rau sab nraud weathering.

Xyuas

Polymer pob zeb tsis tau txais kev noj qab haus huv vim tias cov nqi siab thiab kev nyuab cuam tshuam nrog cov khoom tsim tshuaj. Txawm li cas los xij, txoj kev vam meej tsis ntev los no tau ua rau txo qis rau cov nqi, uas txhais tau hais tias nws txoj kev siv yog maj maj ntau dua. Dua li ntawm tag nrho nws cov kev zoo dua cov pa pob zeb, muaj kev xav txog qhov tsis zoo ntawm tej yam uas feem ntau tshwm sim vim kev tsis zoo, siv cov khoom qis qis thiab cuam tshuam ntawm kev faib tawm.

Tsis tas li ntawd, kev siv technology ntawm polymer pob zeb ntau lawm muaj ntau lub luag hauj lwm thiab secrets uas tsis muaj leej twg xav qhia tawm. Thiab ntawm chav kawm, raws li cov kev txheeb xyuas hais, tus nqi kev lag luam ntawm cov pob zeb polymer yog heev siab. Qhov no yog vim muaj teeb meem ntawm nws cov khoom thiab cov khoom kim heev uas siv los tsim nws.
