Nekukurumidza kukura kwepepa indasitiri, kunyanya bepa rakachekwa rakakuvadzwa nekukurumidza, indasitiri yekudhinda payakagadziriswa mapepa emhando yepamusoro ari kuwedzera uye akakwira. Kuti uve nechokwadi chekudhinda mhando, pamusoro pepepa rakachekwa rinofanira kuve nekugona kuramba kupokana kunyorova. Kurovera kupokana kwekurwisa kunoreva nezve degree rekukuvara pamusoro pepepa mushure meimwe nzvimbo yepepa uye kadhi redzimhosva, iro rinoratidza kugona kwepepa kusaputswa nekupfava .
Uye kune iyo mvura yakachekwa yakavezwa nezvinodiwa, kuitira kuti iite kuti iwane kugona kwemvura uye kudzivisa kwemvura, mukuwedzera kwepepa rekuita mumubatanidzwa uye mamiriro ekutsvaira, anokurumidza kuita Kuti uwedzere kudzikisira kwemvura zvinowedzera zvinowedzera mukubatanidza gadziriro yekugadzirira, kuitira kuti iyo inobatanidza layer kuwana yakanaka yemvura yekudzokorora kwemvura.
Panguva imwecheteyo, zvichibva pane zvekufunga nezvekuchengetedza uye zvakatipoteredza zvinodikanwa zvekuputira pepa uye pepa remusikana zvave kuita zvakanyanya polyrea polyurea formaldehyde resin (Papu) kudzokorora kwemvura. Papu inoshandiswa zvakanyanya, nekuti haina yemahara formaldehyde, uye inokurumidza, inoshanda kana ichinge yasimuka pamushini, uye inogona zvakare kuvandudza zvinobudirira kwepepa rekuchinjisa mukudhinda.
Papu ine chishandiso chakasimba kune ph kukosha, uye viscosity yePapu yakawedzerwa kune pendi yakagadzikana uye kurapa kwekurapa kuri kukurumidza. Papu Molecular Chain Ine ChloroThanol Group uye Polyamine Boka Mapoka maviri anoshanda uye pendi uye pendi yekushambadzira yekusanganisa kuumba scuring yekugadzira network yekuporesa firimu, iyo Ndiro rinonyanya kukwira kwePapu kwemvura, asiwo semvura inobatanidza mumiririri wekushanda mumiriri.
Mukushandisa chaiko, Papu haakwanise kungoumba zvisungo zvemakemikari neyekuchinjisa starch, asi zvakare gadzira Ionic zvisungo neStyrene Butadiene Latedix, uye kupokana kwekupokana kwekubatanidza kunowedzera. Uye zvakare, iyo isina kusimba cation's midziyo yekuramba mumiririri anokwanisa kuburitsa micro-flocculation neanono muCoating, kugadzirisa uye kuvandudza mashandiro ekubatanidza kwepepa rekudhinda.
Rheological gadziriso yakakosha pendi, Papu Type yemvura inodzivirira mumiririri anogona kuwedzera visikopo, kuwedzera Papu yemvura inodzivirira kubva pakukosheswa kwemvura, Kuchengeta kwemvura kuri nani. Papu Tyir Tyir Tyurity yemvura inokwana mumiririri akakodzera kugadzirira kwepamusoro viscosity pendi, uye kudzokorora kwemvura kwekuita kwependi kuri nani.
