Polyurethane muaj ntau cov yam ntxwv zoo heev, yog li nws muaj ntau yam ntawm kev siv tawv ntoo, polyurethane cov khoom siv hluavtaws (polyurethane kuj siv, polyurethane kuj siv hauv kev tsim kho ntawm pej xeem, kev ua kom zoo nkauj Roj av engineering los thaiv dej thiab ruaj khov tsev lossis subgrade; Raws li cov paving cov khoom, nws siv hauv cov kis las, kev khiav, sab hauv tsev cov tsev, thiab lwm yam.
Polyurethane tau faib ua ke li cas?
Cov ua npuas ncauj polyurethans yog muab faib ua npuas (suav nrog cov npuas pu (Polyurethane semi- rigid foams, tseem hu ua semi {2} Tus qauv tshuaj txawv teb chaws thiab cov qauv tshuaj lom neeg, thiab mis proportions. Cov khoom sib txawv nrog ntau yam khoom tuaj yeem tsim tau.
POLYURETHANE muag ua npuas ncauj, feem ntau yog hu ua polyurethane daim txhuam cev lossis ua npuas ncauj, yog hais txog porous lossis retonegent) cov khoom siv elasticity thiab yog tus mos mos. Nws cov khoom siv tau zoo tshaj plaws yog qhov muag muag, nqus cov khoom siv, xws li tsheb, thiab lwm yam khoom siv hauv lub tsheb, thiab cov rooj ua npuas dej, ua kom haum rau lub tsheb thiab kev nqus lub zog thiab ua kom haum Cov yam ntxwv, uas tuaj yeem ua tau raws li cov kev xav zoo li qub thiab dynamic kev lom zem.
Polyurethane Rigid Ua Npuas Ncauj yog ib qho khoom siv hluav taws xob uas yog tam sim no cov khoom siv hluav taws xob, thiab cov tshuab thermal Rwb thaiv tsev cov ntaub ntawv.
Polyurethane semi- Cov khoom lag luam tsis zoo, thiab cov khoom lag luam zoo nkauj rau cov khoom siv tshwj xeeb, ntau yam thiab cov khoom siv hluav taws xob tshwj xeeb} Cov ntaub ntawv polymer.
Kuv ntseeg tias nyob rau yav tom ntej, nrog rau kev txhim kho tsheb kev lag luam thiab thev naus laus zis, kev lag luam polyurethane tom qab kom tau raws li kev nce qib ntawm kev lag luam tsheb.
