Melamine urea-formaldehyde resin ndiyo condensation chigadzirwa chemaitiro pakati pe formaldehyde, urea uye melamine. Idzi resin dzakawedzera kusamira kwemvura uye mamiriro ekunze, zvichiita kuti dzive dzakakodzera kugadzira mapaneru ekushandiswa kwekunze kana hunyoro hwepamusoro. Aya marezeni anopa kushanda kwepamusoro kune mapaneru, ayo anogadzirisa iwo akanyanya kukwira mari yemidziyo. Aya maresin ndiwo anonyanya kushandiswa pakugadzira zvinhu zvekuvaka.
Zvishandiso: Laminated veneer lumber (LVL), particleboard, medium density fiberboard (MDF), plywood.
Melamine urea-formaldehyde resins inowanikwa mune zvakasiyana melamine zvirimo kuti isangane neyakasiyana-siyana yezvinodiwa nevatengi, uye zvigadzirwa zvinogona kugadzirwa zvinoenderana nezvinodiwa nevatengi.
1. Kugadzirwa kwefenicha yemapuranga: Urea-formaldehyde resin poda inogona kushandiswa kubatanidza huni, plywood, matanda pasi uye imwe fenicha yemapuranga. Iine simba rekubatana kwepamusoro uye kupisa kwekudzivirira, uye inogona kupa hukama hunogara kwenguva refu.
2. Papermaking industry: Urea-formaldehyde resin powder inogona kushandiswa sechinhu chinosimbisa chekugadzira mapepa ekugadzirisa simba uye kudzivirira mvura kwepepa. Inogona kuumba hukama hwakasimba pakati pemafiber uye kuwedzera kusimba kwesimba uye kusimba kwepepa.
3. Zvishandiso zvinopisa moto: Urea-formaldehyde resin powder inogona kusanganiswa nezvimwe zvinhu kuti zvigadzire mabhanhire anopisa moto uye zvinonamatira zvinopisa moto. Izvi zvinhu zvinodzoreredza moto zvinoshandiswa zvakanyanya mumidziyo yemagetsi, kuvaka, uye chekufambisa kupa kuchengetedzwa kwemoto.
4. Indasitiri yekuputira: Urea-formaldehyde resin poda inogona kushandiswa kugadzira machira ane kunaka kwekupisa uye kusagadzikana kwemamiriro ekunze. Aya machira ane akanakisa kukwenya kuramba uye makemikari kuramba uye anoshandiswa zvakanyanya mumotokari, kuvaka uye mamwe minda.
5. Indasitiri yekugadzira micheka: Urea-formaldehyde resin powder inewo maitiro akawanda mumhizha yekugadzira machira. Inogona kushandiswa kugadzira machira akasiyana-siyana, akadai sesilika, machira emvere dzemakwai, nezvimwewo. Mucheka wakasungirirwa neurea-formaldehyde resin poda ine mvura yakasimba yekudzivirira uye kusimba, uye haisi nyore kupera uye kukanganisa. Pamusoro pezvo, urea-formaldehyde resin poda inogonawo kushandiswa kugadzira machira akasiyana-siyana ekudzivirira mvura, anti-wrinkle agents, nezvimwewo, zvichiita kuti jira racho rive rakanaka uye rinoshanda.
6. Adhesive: Urea-formaldehyde resin poda inogona kushandiswa seyakawanda yekunamatira yekubatanidza simbi, girazi, ceramics nezvimwe zvinhu. Iyo ine yakanaka yekudzivirira mvura uye makemikari kuramba uye yakakodzera kune akasiyana maindasitiri bonding application.
Muchidimbu, urea-formaldehyde resin poda inonamira yemhando yepamusoro uye yakasimba kusimba uye kudzivirira mvura. Inoshandiswa zvakanyanya mukubatanidza zvinhu zvakaita sehuni, zvigadzirwa zvemapepa, uye machira. Pamusoro pezvo, urea-formaldehyde resin poda inogona zvakare kushandiswa kugadzira zvinhu zvinokurisa, zvinodzivirira zvinhu, anti-corrosion coatings, nezvimwewo, uye ine huwandu hwakawanda hwekushandisa uye tarisiro yekushandisa.
