Ob-cov khoom nplaum - ib pawg ntawm cov nplaum zoo uas tsis muaj cov kuab tshuaj. Lub ntsiab Cheebtsam yog resins (binders) thiab hardeners (sib cais cia, yuav ua tau nyob rau hauv daim ntawv ntawm kev ncua los yog nyob rau hauv hmoov).

Raws li qhov tshwm sim ntawm cov tshuaj tiv thaiv tshuaj uas pib tom qab sib xyaw ob yam khoom no, cov khoom sib xyaw ua kom tawv, tau txais qhov kev sib txuas thawj zaug tom qab ob peb feeb. Lub curing ceev yog loj nyob ntawm qhov kub thiab txias thiab qhov zoo ntawm pre-stripping. Lub zog kawg tau txais tom qab ob peb teev ntxiv.

Ob lub ntsiab lus epoxy nplaum yog npaj raws nraim raws li cov lus qhia, raws li qhov sib piv thiab lub sijhawm raug qhia hauv nws. Thaum gluing ob ntu, koj tuaj yeem thov tus activator ntawm ib feem thiab cov resin ntawm lwm qhov. Thaum txuas nrog, cov khoom sib txuas tau raug hu raws li tau piav qhia saum toj no.

Qhov chaw tseem ceeb ntawm kev thov rau epoxy nplaum yog cov khoom tsis ntxeem tau (txhua yam tab sis hluavtaws) uas yuav tsum tau ua kom ruaj ntseg. Rau lub zog ntau dua, cov resin tuaj yeem ua taureinforced nrog fiberglass. Cov txheej txheem no tso cai rau kev daws teeb meem nyuaj uas tshwm sim, piv txwv li, thaum kho cov tshuab. Qee lub sij hawm muaj kev faib ua feem ntau ntawm cov hmoov hlau yog ntxiv rau ob lub ntsiab lus nplaum thiab siv los ua cov vuam txias. Cov khoom sib txuas hauv txoj kev no tau nce lub zog.

Ob lub ntsiab lus polyurethane nplaum, uas yog siv nyob rau hauv yuav luag txhua qhov chaw, kuj tshwj xeeb yog ruaj thiab txhim khu kev qha. Nws zoo kawg nkaus glues tawv blanks nrog lub hauv caug, ntoo ntsiab (xws li hnyav sawv daws yuav), txhuas, iav, hlau lug, ntuj pob zeb. Cov nplaum ob lub ntsiab lus no tsis ntshai ntawm cov dej noo, yog li nws yog qhov tsim nyog rau kev tsim ua haujlwm hauv chav nrog cov av noo siab (piv txwv li, hauv chav dej, hauv chav da dej, thiab lwm yam). Nws yog qhov zoo tagnrho rau kev ua haujlwm tiling (xws li tso cov qauv thiab mosaics), rau gluing joinery, kom tiav pob zeb facades.

Ua tsaug rau cov nplaum polyurethane, nteg lub "sov pem teb" system txuag tsis tau tsuas yog lub sij hawm, tab sis kuj nyiaj txiag thiab kev rau siab. Txawm hais tias hom flooring, twb tom qab yim teev koj tuaj yeem tsis tsuas yog taug kev ntawm nws, tab sis kuj npaj rooj tog. Cov kua nplaum no (tsis zoo li analogs) yuav luag tsis elastic, thiab yog li ntawd tsis ntsws thiab tsis ncab. Cov khoom zoo no tau khaws cia txawm tias muaj qhov hnyav heev.

Kev ntseeg tau yog ib qho ntawm cov kev xaiv tseem ceeb rau cov chaw tsim khoom khau thiab cov khau me me. Txawm li cas los xij ntawm ib tus qauv (PVC,ntxeem tau, thiab lwm yam), khau polyurethane nplaum tuav cov chaw kom ruaj khov tias nws yooj yim tsis tuaj yeem tawg tom qab ziab. Cov khau no tsis ntshai los nag, muab qhov kaj, kev nplij siab thiab kev zoo siab.

Ob-cov khoom nplaum (polyurethane, epoxy) tshwj xeeb yog muaj zog thiab ruaj khov, kho qhov tsis zoo, cov pob qij txha, cov pob qij txha thiab ntseeg siab hloov cov analogues. Lawv tau siv nyob rau hauv yuav luag txhua hom kev ua haujlwm, tsis hais txog theem ntawm kev nyuaj. Ceramics, vuas, cib txeeb kom tuag, yog vim li cas cov neeg uas twb tau siv ob lub nplaum nplaum xaiv dua.
