Polymer pob zeb yog cov khoom siv hauv tsev tshwj xeeb uas yog siv los ua cov khoom sib txuas thiab tseem los hloov cov txiv qaub cement. Qee zaum, cov polymer yog siv los ua ib qho ntxiv rau Portland cement. Nws yog ntau yam, cov khoom siv ruaj khov uas tau los ntawm kev sib xyaw ntau cov ntxhia hauv cov khoom siv hluavtaws lossis cov khoom siv ntuj tsim. Cov khoom siv thev naus laus zis no tau siv ntau hauv kev lag luam, tab sis feem ntau muaj nyob rau hauv kev tsim kho kev lag luam.

Peb hom polymer pob zeb siv hauv kev tsim kho. Tom ntej no, peb yuav ua tib zoo saib lawv cov thev naus laus zis tsim khoom, cov peev txheej thiab cov khoom sib xyaw kom muaj lub tswv yim dav dav ntawm cov khoom siv polymer thiab lawv cov kev hloov kho.
Polymer compounds for concrete (polymer modified concrete)
hom pob zeb no yog ua los ntawm Portland cement khoom nrogHloov kho polymer xws li acrylic, polyvinyl acetate thiab ethylene vinyl acetate. Nws muaj adhesion zoo, siab dabtsi yog khoov zog thiab tsis tshua muaj permeability.
Acrylic polymer hloov ua vaj tse muaj xim ntev, uas yog vim li cas nws thiaj li xav tau ntau ntawm cov neeg tsim khoom thiab cov kws tsim qauv. Nws cov tshuaj hloov kho yog zoo ib yam li cov tsoos cement variation. Tus nqi ntawm polymer feem ntau yog 10 mus rau 20%. Qhob hloov nyob rau hauv no txoj kev muaj ib tug tsawg degree ntawm permeability thiab ib tug siab ceev tshaj li ntshiab cement. Txawm li cas los xij, nws cov qauv kev ncaj ncees yog nyob ntawm qhov khi ntawm Portland cement.
pob zeb yuav siv sij hawm ntev dua kom degrade yog tias nws muaj qhov ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom. Kev txhim kho tus txheeb ze ntawm cov tshuaj tiv thaiv ntawm cov khoom siv polymer-hloov rau Portland cement yog ua tau nyob rau hauv ib puag ncig acidic.
polymer-impregnated qhob
Polymer impregnation rau cov pob zeb feem ntau yog ua los ntawm kev sib xyaw cov monomer uas tsis tshua muaj siab rau hauv hydrated Portland cement tom qab hluav taws xob lossis thermal catalytic polymerization. Lub modulus elasticity ntawm hom pob zeb no yog 50-100% siab dua li cov pa ua vaj tse.
Txawm li cas los xij, cov qauv polymer yog 10% ntau dua li cov pob zeb ib txwm. Ua tsaug rau cov yam ntxwv zoo no, ntawm ntau daim ntawv thov ntawm cov khoom siv hauv tsev polymer, ntau lawm tuaj yeem sau tseg:
- decks;
- choj;
- pipes;
- vuas pem teb;
- tsev laminate.
Cov txheej txheem siv thev naus laus zis suav nrog kev ziab cov pob zeb kom tshem tawm cov dej noo ntawm nws qhov chaw, siv cov monomers hauv txheej nyias ntawm cov xuab zeb, thiab tom qab ntawd polymerizing cov monomers siv cov cua sov. Yog li ntawd, cov pob zeb pob zeb muaj cov dej permeability qis dua, nqus dej, ua kom tsis zoo thiab feem ntau muaj zog. Tsis tas li ntawd, txhawm rau txhawm rau txhawm rau hnav tsis kam, tiv taus txias thiab ya raws, cov kua roj vanish polymer yog siv rau pob zeb, cib, pob zeb, pem teb, thiab lwm yam.
polymer concrete
Tsis muaj dab tsi ua nrog peb li niaj zaus Portland cement. Nws yog tsim los ntawm kev sib txuas cov pob zeb nrog cov polymeric binder uas tsis muaj dej. Polystyrene, acrylic thiab epoxy resins yog monomers uas tau siv dav hauv kev tsim cov pob zeb no. Sulfur kuj suav hais tias yog polymer. Sulfur pob zeb yog siv rau cov tsev uas xav tau cov kua qaub siab. Thermoplastic polymers, tab sis feem ntau yog thermoset resins, yog siv los ua lub ntsiab polymer tivthaiv vim lawv cov thermal stability thiab tsis kam mus rau ntau yam tshuaj.
Polymer pob zeb yog tsim los ntawm cov khoom sib xyaw uas suav nrog silicon dioxide, quartz, granite, limestone thiab lwm yam khoom zoo. Chav tsev yuav tsum yog qhov zoo, tsis muaj plua plav, khib nyiab thiab dej noo ntau dhau. Kev ua tsis tau raws li cov txheej txheem no tuaj yeem ua tautxo lub zog ntawm daim ntawv cog lus ntawm polymer binder thiab aggregate.
Txoj kev ntawm cov pob zeb polymer
Cov khoom siv hauv tsev niaj hnub txawv ntawm nws cov neeg ua ntej. Nws muaj cov yam ntxwv hauv qab no:
- High resistance to chemical and biological media.
- Piv rau cov khoom cement-pob zeb, nws muaj qis dua.
- Zoo heev ntawm kev nqus suab nrov thiab kev co.
- zoo huab cua thiab UV tiv taus.
- nqus dej.
- Tau txiav nrog laum thiab grinders.
- Yuav siv tau ua pob zeb crushed los yog crushed siv raws li txoj kev.
- Kwv yees li 4 npaug zog dua li cov cement pob zeb.
- zoo thermal rwb thaiv tsev thiab ruaj khov.
- Ultra-smooth tiav uas txhawb nqa hydraulic ntws zoo.
Siv
Polymer pob zeb siv tau rau kev tsim kho tshiab lossis kho dua tshiab ntawm cov khoom qub. Nws cov khoom nplaum ua rau nws tuaj yeem rov qab tau ob qho tib si polymeric thiab cov pa cement-based concretes. Nws tsis tshua muaj permeability thiab corrosion kuj ua rau nws haum rau siv nyob rau hauv cov pas dej da dej, cov kav dej phwj tuaj, cov kav dej, cov hlwb electrolytic thiab lwm cov qauv uas muaj cov kua dej los yog cov tshuaj hnyav. Nws yog qhov tsim nyog rau kev tsim kho kom zoo thiab kho dua tshiab vim nws muaj peev xwm tiv taus cov pa phem thiab corrosive cov kav dej thiab cov kab mob uas feem ntau pom hauv cov kav dej.
Tsis zoo li cov qauv ua vaj tse ib txwm muaj, nws tsis tas yuav tsum tau txheej lossis vuam ntawm cov khoom tiv thaiv PVC seams. Koj tuaj yeem pom kev siv cov pob zeb polymer ntawm txoj kev hauv nroog. Nws yog siv nyob rau hauv kev tsim kho ntawm txoj kev thaiv, txoj kev taug kev, kwj deg, qhov chaw. Tsis tas li ntawm txoj kev, cov txheej txheem polymer rau cov pob zeb tau ntxiv rau asph alt thaum lub sijhawm tsim kho ntawm thaj chaw qhib, cov chaw khiav thiab lwm yam khoom uas tau qhib thiab raug cuam tshuam los ntawm kev cuam tshuam rau sab nraud atmospheric.
Reviews
Polymer pob zeb tsis tau txais kev pom zoo vim yog tus nqi siab thiab teeb meem cuam tshuam nrog cov txheej txheem tsim khoom ib txwm muaj. Txawm li cas los xij, kev nce qib tsis ntev los no tau ua rau txo tus nqi tseem ceeb, txhais tau tias nws siv tau maj mam dhau los ua ntau dua. Txawm hais tias tag nrho nws cov txiaj ntsig zoo dua li cov pa ua vaj tse, muaj cov kev xav txog qhov tsis zoo ntawm ib puag ncig uas feem ntau tshwm sim vim kev tsim khoom tsis raug, siv cov khoom siv tsis zoo thiab tsis sib xws.
Tsis tas li, thev naus laus zis rau kev tsim cov pob zeb polymer muaj ntau yam nuances thiab secrets uas tsis muaj leej twg xav qhia. Thiab tau kawg, raws li kev txheeb xyuas sau tseg, kev lag luam tus nqi ntawm cov pob zeb polymer yog siab heev. Qhov no yog vim qhov nyuaj ntawm kev tsim nws thiab cov khoom kim heev uas siv los tsim nws.
