Umkhwa wophuhliso lwezincamathelisi zokwenziwa emhlabeni ugxininiswa ngokukhuselwa kwendalo kunye nokusebenza okuphezulu, kunye nemithetho engqongqo yokukhuselwa kwendalo, amazwe aphuhlileyo aphuhlisa ngamandla ancamathelayo asekelwe emanzini. Ngenxa yokusebenza okuphezulu okubanzi kokuncamatheliswa kwepolyurethane emanzini, iyodwa kuzo zonke iintlobo zokuncamathelisa ezisemanzini, kwaye ifumene ingqwalasela enkulu ekhaya nakwamanye amazwe kule minyaka yakutshanje, ngakumbi uphuhliso kunye nophando lwezinto zokuncamathelisa ezisebenza emanzini zepolyurethane ziye zaba shushu. isihloko.
I-Waterborne polyurethane resin (PUD) yi-emulsion efanayo eyenziwa ngokusasaza i-polyurethane emanzini, enenzuzo ye-VOC ephantsi, i-odor ephantsi, i-non-bustible, i-extra-mechanical properties, ukusebenza kakuhle kunye nokusebenza. I-PUD inokusetyenziswa ngokubanzi kwi-adhesives, isikhumba sokwenziwa, iingubo, ii-inki kunye namanye amashishini.
I-polyurethane resin yamanzi njenge-adhesive, kunye nokusebenza okulula, ukumelana nobushushu obugqwesileyo kunye nezinye iimpawu, zingasetyenziselwa iindidi ze-substrate bonding, ezisetyenziswa ngokubanzi kwiglue yesihlangu, i-automotive glue yangaphakathi, i-vacuum plastic, i-adhesive ye-woodworking kunye nezinye iindawo, i-U1115H, I-U1115, i-U1115L ziintlobo ezintathu ze-anionic waterborne polyurethane dispersions, apho i-U1115H ifaneleka ngokukodwa. iimeko eziphezulu zokumelana nobushushu bokuqala, i-U1115L ifanelekile ngokukodwa kwiimeko ezineemfuno eziphezulu ze-viscosity.
I-polyurethane yamanzi inoluhlu olukhulu lwezinto ezibonakalayo emva kokubunjwa kwefilimu, kunye nokuchasana okubandayo okubandayo, ukuxhathisa i-solvent, ukubunjwa kwefilimu, ukuxhathisa, ukuxhathisa okomileyo nokumanzi, ukunamathela kunye nezinye izinto ezilungileyo, zinokusetyenziswa njengengubo ye-substrates eyahlukeneyo, esetyenziswa ngokubanzi. kwi-ejenti yokugqiba ngesikhumba, iingubo zokwaleka, i-synthetic yesikhumba kunye nezinye iindawo.
Ngamafutshane, ngenxa yeenzuzo ezininzi zokunamathiswa kwe-polyurethane yamanzi, ukusetyenziswa kwabo kuye kwanda kakhulu, kwaye kukho iindidi ezininzi. Ngokwengqikelelo yeengcali ezifanelekileyo, imfuno yokuncamatheliswa kokwenziwa e-China inentengiso ebanzi, kwaye izinto zokuncamathelisa ezifumaneka emanzini ziyoyisile imarike ngokusebenza kwazo okuphezulu kunye nokukhuselwa kwendalo kunye nokonga amandla, kwaye imveliso yazo kunye nomda wokusebenzisa ukhula ngokukhawuleza kwaye ukhuthaza. . Kakade ke, iintsilelo zayo nazo zifuna ukusonjululwa nzulu ngakumbi. I-China iya kugxila ekuphuhliseni i-adhesives ye-polyurethane yamanzi, kwaye iya kwazisa izixhobo eziphambili ezisekelwe kwi-teknoloji yokuziphuhlisa ukuphuhlisa "i-green" i-solvent-based based, i-non-yellow-shaped, i-high-resistant-heat-resistant kunye ne-high-performance adhesives ye-PU; Phuhlisa inncamatheliso ye-PU eshushu enyibilikayo encamathelayo, ukusebenza okuphezulu kokuncamathelisa kolwakhiwo lwePU kunye nexabiso eliphantsi lokuncamathelisa kwepolymer polyisocyanate emanzini, ukuze inqanaba lilonke lokuncamathelisa kwePU eTshayina lifikelele kwinqanaba eliphezulu langoku emhlabeni.
