Mafambiro ekugadzirwa kwezvakanamira munyika zvinoratidzwa nekuchengetedzwa kwezvakatipoteredza uye kushanda kwepamusoro, nekuwedzera kusimba kwemitemo yekuchengetedza kwezvakatipoteredza, nyika dzakabudirira dzinogadzira zvine simba zvinonamira pamvura. Nekuda kwekuita kwepamusoro-soro kwezvinonamira zvepolurethane mumvura, zvakasiyana mumarudzi ese emanamira emvura, uye yakawana kutariswa kwakanyanya kumba nekune dzimwe nyika mumakore achangopfuura, kunyanya kuvandudzwa uye tsvakiridzo yeadhesives yepolurethane yemhando yepamusoro yave kupisa. topic.
Waterborne polyurethane resin (PUD) iuniform emulsion inoumbwa nekuparadzira polyurethane mumvura, ine zvakanakira ye low VOC, yakaderera kunhuhwirira, isingabatike, yakanakisa mechanical zvivakwa, nyore kushanda uye kugadzirisa. PUD inogona kushandiswa zvakanyanya mukunamira, ganda rekugadzira, machira, ingi uye mamwe maindasitiri.
Waterborne polyurethane resin sechinhu chinonamira, ine nyore activation, yakanakisa kupisa kupisa uye humwe hunhu, inogona kushandiswa kwakasiyana-siyana substrate bonding, inoshandiswa zvakanyanya mune shangu glue, mota yemukati guruu, vacuum plastic, woodworking adhesive uye mamwe minda, U1115H, U1115, U1115L inofananidzira matatu anionic waterborne polyurethane dispersions, iyo U1115H inonyanya kukodzera kune yakakwirira yekutanga kupisa kupisa kwemaitiro ekushandisa, U1115L inonyanya kukodzera mamiriro ane yakakwirira viscosity zvinodiwa.
Waterborne polyurethane ine hukuru hwakakura hwezvinhu zvemuviri mushure mekugadzirwa kwefirimu, ine yakanaka kutonhora kupikisa, kunyungudutsa, kuumbwa kwefirimu, tortuous resistance, yakaoma uye yakanyorova rub resistance, adhesion uye zvimwe zvakanakira, inogona kushandiswa seyakaputira akasiyana substrates, anoshandiswa zvakanyanya. mumatehwe ekupedzisa agent, machira ekuputira, synthetic dehwe uye mamwe minda.
Muchidimbu, nekuda kwezvizhinji zvakanakira zvekunamira kwemvura polyurethane, kushandiswa kwavo kwakawedzera uye kwakawedzera, uye kune akawanda uye akawanda marudzi. Zvinoenderana nekufanotaura kwenyanzvi dzakakodzera, kudiwa kwezvigadzirwa zvekunamira muChina zvine musika wakafara, uye zvinonamira mumvura zvepolurethane zvakakunda musika nekuita kwavo kwepamusoro uye kuchengetedza kwezvakatipoteredza uye kuchengetedza simba, uye kugadzirwa kwavo uye chiyero chekushandisa chiri kukurumidza kuwedzera nekusimudzira. . Zvechokwadi, kukanganisa kwayo kunodawo kugadziriswa zvakadzama. China ichatarisa kugadzirwa kwemvura ine polyurethane adhesives, uye ichaunza yakakosha michina inoenderana neyakagadziridza tekinoroji yekugadzira "green" solvent-based, isina-yellow-shaped, high-heat-resistant uye yakakwirira-performance PU adhesives; Gadzira reactive PU inopisa inonyunguduka inonamira, yakakwira-inoshanda PU yakarongeka inonamira uye yakaderera-inodhura yemvura polymer polyisocyanate adhesive, kuitira kuti iyo yese nhanho yePU yekunamira muChina isvike pazvino nhanho yepamusoro pasirese.
