Polyurea yog cov organic polymer uas yog cov tshuaj tiv thaiv ntawm isocyanate nrog amine terminated polyether resin, tsim cov yas zoo li los yog roj hmab zoo li cov khoom sib txuas uas yog seamless membrane.
Polyurea xav tau kev cob qhia tshwj xeeb thiab cov cuab yeej siv rau daim ntawv thov teb, txawm tias siv los ua kev sib koom ua ke los yog ua ib daim ntawv thov txheej.Shundi muaj qhov kev pab cuam txuas ntxiv ntawmkev cob qhia tus neeg cog lusnyob rau hauv qhov chaw.Muaj cov neeg ua haujlwm tsim nyog hauv Suav teb.
Raws li txoj cai dav dav,Shundipolyurea tuaj yeem ua haujlwm kom muaj cov khoom siv uas tuaj yeem tso ncaj qha mus rau hauv cov kav dej huv huv.Nws tuaj yeem siv rau txhua qhov pob zeb, hlau, ntoo, fiberglass, ceramics nto.
Shundi polyureas pib tsim lawv lub cev lub cev nyob rau hauv feeb ntawm daim ntawv thov.Kho polyurea tuaj yeem tiv taus qhov kub ntawm -40 ℃ to 120 ℃, Thaum polyurea muaj qhov hloov pauv iav siab thiab kub ntawm deflection kub, nws yuav kub hnyiab thaum raug hluav taws xob ncaj qha.Nws yuav tua tus kheej thaum hluav taws raug tshem tawm.Tab sis peb kuj muaj hluav taws kub-retardant polyurea rau cov kev cai tshwj xeeb xws li subway tunnels thiab txoj kev tsheb.
Polyurea tej zaum yuav yog ib qho nyuaj los yog mos nyob ntawm seb tus qauv tsim thiab kev npaj siv.Durometer ratings tej zaum yuav txawv ntawm Shore A 30 (mos heev) rau Shore D 80 (nyuaj heev).
Tiag tiag muaj ob hom sib txawv ntawm aliphatic polyurea systems tam sim no nyob rau hauv kev ua lag luam.Ib qho yog qhov raug kub siab / kub txau tshuab thiab lwm qhov yog qhov hu ua "polyaspartic polyurea" hom kab ke.Qhov no polyaspartic system txawv nyob rau hauv uas nws siv ib tug ester-raws li resin tivthaiv thiab muaj ib tug ntev lub lauj kaub.Nws tuaj yeem siv tes siv cov chais;txhuam hniav;rakes los yog txawm airless sprayers.Cov txheej txheem aspartic tsis yog lub siab tsim txheej txheem ntawm "kub tsuag" polyurea systems.Cov txheej txheem uas muaj ntxhiab polyurea yuav tsum tau ua tiav los ntawm kev kub siab, rhuab ntau ntau cov twj tso kua mis thiab txau los ntawm ib qho impingement hom tshuaj tsuag phom.Qhov no kuj muaj tseeb rau cov aliphatic version ntawm hom kab ke no, qhov sib txawv ntawm qhov tseem ceeb yog xim ruaj khov ntawm aliphatic systems.
Txhua yam khoom ntawm peb lub vev xaib muaj cov kab kos tshuaj tiv thaiv hauv qab Cov Ntaub Ntawv tab.
Ib qho ntawm peb cov neeg ua haujlwm thaum nws los txog rau cov tshuaj lom neeg hnyav heev yog SWD959Tsis tas li ntawd, yog tias koj muaj cov tshuaj tshwj xeeb uas koj tab tom cuam tshuam nrog (lossis ib daim ntawv thov tshwj xeeb), xav tias dawb rautiv tauj pebyog li peb tuaj yeem pab koj txiav txim siab qhov zoo tshaj plaws rau koj cov kev xav tau.
Peb muaj cov dej noo kho urethane txheej thiab tawv polyaspartic txheej uas muaj kev ua haujlwm siab ntawm cov tshuaj tiv thaiv rau cov kuab tshuaj, acids lossis lwm cov kuab tshuaj.Nws tuaj yeem tiv taus 50% H2SO4thiab 15% HCL.
Nws nyob ntawm tus qauv tsim, txawm hais tias hauv Shundi cov qauv tshwj xeeb, polyurea yuav tsis ntsws tom qab nws kho.
Txawm li cas los xij, qhov no yog ib lo lus nug zoo los nug txog leej twg koj xaiv yuav khoom los ntawm - puas yog koj cov khoom poob qis los yog tsis?
Peb muaj cov khoom zoo tshaj plaws rau hom kev thov no, SWD9005, Cov khoom no tau raug sim ntau hauv kev lag luam mining, thiab tau ua raws li qhov kev cia siab.
Rau immersion / steel daim ntaub ntawv, nco ntsoov tias PUA (polyureas) thiab epoxy tsis zoo ib yam.Lawv yog ob qho tib si piav qhia txog technologies / ib hom khoom.PUA cov tshuab ua haujlwm tau zoo rau kev tso dej, tab sis lawv yuav tsum tau tsim kom raug rau daim ntawv thov ntawd.
Thaum cov tshuab epoxy muaj qhov nruj dua, PUA cov tshuab muaj qhov yooj yim dua thiab qis permeation tus nqi rau cov qauv tsim kom raug.PUA kuj tseem yog cov khoom siv rov qab mus rau kev pabcuam sai dua nyob rau hauv feem ntau - polyurea kho tsis pub dhau ob peb teev piv rau hnub (lossis qee lub lis piam) rau epoxies.Txawm li cas los xij, qhov teeb meem loj nrog hom kev ua haujlwm no thiab cov hlau substrates yog qhov kev npaj saum npoo yog qhov tseem ceeb.Qhov no yuav tsum tau ua kom zoo / tag.Qhov no yog qhov uas feem ntau muaj teeb meem thaum sim cov hom phiaj no.
Tshawb xyuas pebDaim ntawv thovpaj casrau cov profiles ntawm no thiab ntau hom kev siv.
Feem ntau, ib qho zoo 100% acrylic latex tsev xim ua haujlwm zoo tshaj cov tshuaj tsuag polyurea.Feem ntau nws yog qhov zoo tshaj plaws rau lub tsho tiv no ntawm polyurea (sooner dua tom qab) hauv 24 teev ntawm daim ntawv thov.Qhov no txhawb qhov zoo tshaj plaws adhesion.Polyaspartic uv kuj topcoat yog pom zoo kom siv tshaj polyurea kom zoo dua los tiv thaiv kev laus thiab huab cua tsis kam.
