Polyurea iorganic polymer ndiko kuita kweisocyanate ine amine yakamiswa polyether resin, ichigadzira purasitiki-senge kana rabha-sekomboni isina musono membrane.
Polyurea inoda kudzidziswa kwakakosha uye michina yekushandisa mumunda, ingave yakashandiswa seyakabatana filler kana semunda wakaiswa coating.Shundi ine chirongwa chinoenderera mberi chekontrakta kudzidziswapanzvimbo.Kune vanyoreri vanokwanisa muChina.
Sezvo mutemo,Shundipolyurea inogona kushandiswa kuve nechero chinhu chinogona kuburitswa zvakananga mumaseji etsvina.Inogona kuiswa pane chero kongiri, simbi, huni, fiberglass, ceramics pamusoro.
Shundi polyureas inotanga kukudziridza zvimiro zvavo zvemuviri mukati memaminitsi ekushandisa.Yakarapwa polyurea inogona kuramba tembiricha kubva -40 ℃ kusvika 120 ℃, Nepo polyurea ine yakakwira girazi shanduko uye kupisa kwekushisa kwekutsauka, inopisa kana yaiswa murazvo wakananga.Ichadzima yega kana murazvo wabviswa.Asi isu tine zvakare-inodzoreredza moto polyurea kune zvakakosha zvinodiwa senge subway tunnel uye nzira dzetraffic.
Polyurea inogona kunge yakaoma kana kuti yakapfava zvichienderana nekumwe kuumbwa uye kushandiswa kwakarongwa.Durometer ratings inogona kubva paShore A 30 (yakapfava kwazvo) kuenda kuShore D 80 (yakaoma kwazvo).
Chaizvoizvo kune marudzi maviri akasiyana ealiphatic polyurea masisitimu ari pamusika.Imwe ndiyo yakajairika high pressure/ tembiricha yakapfapfaidza masisitimu uye imwe ndiyo inozivikanwa se "polyaspartic polyurea" mhando system.Iyi polyaspartic system yakasiyana pakuti inoshandisa ester-based resin component uye ine hupenyu hurefu hwehari.Inogona kushandiswa nemaoko uchishandisa rollers;mabhurashi;rakes kana kunyange masprayers asina mweya.Iyo aspartic masisitimu haisi iyo yakakwirira yekuvaka coating yakafanana neye "hot spray" polyurea masisitimu.Iyo yakajairwa inonhuhwirira polyurea masisitimu inofanirwa kugadziriswa kuburikidza nekudzvanyirira kwakanyanya, kudziya kwehuwandu hwechikamu pombi uye kupfapfaidzwa kuburikidza neipingement mhando yekupfapfaidza-pfuti.Izvi ndezvechokwadi zvakare kune aliphatic vhezheni yerudzi urwu rwehurongwa, mutsauko wekutanga kuve kugadzikana kwemavara eiyo aliphatic system.

Tine hunyoro hwekurapa urethane coating uye yakasimba polyaspartic coating iyo ine yakakwirira kuita kwemakemikari kuramba kune zvinonyungudutsa, acids kana zvimwe zvinonyungudutsa.Inogona kuramba 50% H2SO4uye 15% HCL.
Izvo zvinoenderana nekugadzirwa, kunyangwe mune mamwe magadzirirwo aShundi, iyo polyurea haizodzikira mushure mekunge yapora.
Zvisinei, uyu mubvunzo wakanaka kubvunza chero munhu waunosarudza kutenga zvinhu kubva kwaari - zvinhu zvako zvinodzikira here kana kuti kwete?

Kunyudza / kushandiswa kwesimbi, ramba uchifunga kuti PUA (polyureas) uye epoxy hazvina kufanana.Iwo ese ari maviri tsananguro yetekinoroji / rudzi rwechigadzirwa.PUA masisitimu anoshanda nemazvo pakunyudzwa, asi anofanirwa kugadzirwa nemazvo kune iyo application.
Nepo epoxy masisitimu akanyanya kuomarara, PUA masisitimu ane yepamusoro kuchinjika uye yakaderera permeation mareti emasisitimu akagadzirwa zvakanaka.PUA zvakare inokurumidza kudzoka-ku-sevhisi zvinhu zvakajairika - polyurea inorapa mukati memaawa zvichienzaniswa nemazuva (kana dzimwe nguva mavhiki) epoxies.Zvisinei, nyaya huru nemhando iyi yebasa uye simbi substrates ndeyokuti kugadzirira kwepamusoro kunokosha.Izvi ZVINOFANIRA kuitwa nemazvo / zvakakwana.Apa ndipo apo vazhinji vanga vaine matambudziko pakuyedza mapurojekiti emhando iyi.
