Umkhuba wokuthuthukiswa kwezinamatheliso zokwenziwa emhlabeni uqokonyiswa ukuvikelwa kwemvelo nokusebenza okuphezulu, nemithethonqubo eqinile yokuvikela imvelo, amazwe athuthukile athuthukisa ngamandla ama-adhesives asekelwe emanzini. Ngenxa yokusebenza okuphezulu okubanzi kwezinamathiselo ze-polyurethane emanzini, ihlukile kuzo zonke izinhlobo zokunamathela emanzini, futhi iye yathola ukunakwa okukhulu ekhaya naphesheya eminyakeni yamuva, ikakhulukazi ukuthuthukiswa kanye nocwaningo lwezinamathiselo ze-polyurethane ezisebenza kahle emanzini seziphenduke ukushisa. isihloko.
I-Waterborne polyurethane resin (PUD) iyi-emulsion efanayo eyakhiwe ngokuhlakaza i-polyurethane emanzini, enezinzuzo ze-VOC ephansi, iphunga eliphansi, elingashi, izakhiwo ezinhle kakhulu zemishini, ukusebenza okulula nokucubungula. I-PUD ingasetshenziswa kabanzi kuma-adhesives, isikhumba sokwenziwa, i-coatings, oyinki nezinye izimboni.
I-polyurethane resin emanzini njengendlela yokunamathela, esebenza kalula, ukumelana nokushisa okuhle kakhulu nezinye izici, ingasetshenziswa ezinhlobonhlobo ze-substrate bonding, esetshenziswa kabanzi ku-glue yesicathulo, ingcina yezimoto yangaphakathi, ipulasitiki ye-vacuum, i-woodworking adhesive kanye nezinye izinkambu, U1115H, U1115, U1115L ama-anionic waterborne polyurethane dispersions ajwayelekile, lapho i-U1115H ifaneleka ngokukhethekile. izimo eziphezulu zokumelana nokushisa kokuqala, i-U1115L ifaneleka ngokukhethekile izimo ezinezidingo eziphezulu ze-viscosity.
I-Waterborne polyurethane inohlu olukhulu lwezakhiwo zomzimba ngemuva kokwakheka kwefilimu, enokumelana okuhle okubandayo, ukumelana ne-solvent, ukwakheka kwefilimu, ukumelana ne-tortuous, ukumelana nokukhuhla okomile nokumanzi, ukunamathela nezinye izinzuzo, ingasetshenziswa njengendlela yokumboza ama-substrates ahlukahlukene, asetshenziswa kabanzi. ku-ejenti yokuqedela lesikhumba, ukumbozwa kwendwangu, isikhumba sokwenziwa kanye neminye imikhakha.
Ngamafuphi, ngenxa yezinzuzo eziningi zokunamathela kwe-polyurethane emanzini, ukusetshenziswa kwabo kuye kwanda kakhulu, futhi kunezinhlobo eziningi kakhulu. Ngokwesibikezelo sochwepheshe abafanelekile, isidingo sezinamatheliso zokwenziwa eChina sinemakethe ebanzi, futhi izinto zokunamathisela ezenziwe ngamanzi ze-polyurethane ziye zanqoba imakethe ngokusebenza kwazo okuphezulu nokuvikelwa kwemvelo nokonga amandla, futhi ukukhiqizwa kwazo kanye nobubanzi bokusebenza kwazo kukhula ngokushesha futhi kukhuthaza. . Yebo, ukushiyeka kwayo nakho kudinga ukuxazululwa ngokujula okwengeziwe. I-China izogxila ekuthuthukisweni kwezinamatheliso ze-polyurethane emanzini, futhi izokwethula imishini ebalulekile esekelwe kubuchwepheshe obuthuthukisiwe ukuze kuthuthukiswe izinamatheliso ze-PU "eziluhlaza", ezingaphuzi, ezingashisi kakhulu nezisebenza kakhulu; Yakha ingcina enamathelayo ye-PU eshisayo encibilikayo, ingcina yesakhiwo se-PU esebenza kakhulu kanye ne-adhesive ye-polymer polyisocyanate ebiza kancane etholakala emanzini, ukuze izinga eliphelele le-PU enamathelayo e-China lifinyelele izinga lamanje elithuthukile emhlabeni.
