Melamine urea-formaldehyde resin chinhu chinokonzereswa nekusanganiswa kwemvura nemafuta kubva mukuita kweformaldehyde, urea nemelamine. Maresini aya ane simba rekudzivirira mvura nemamiriro ekunze, zvichiita kuti akwanise kugadzira mapaneru ekushandisa panze kana mamiriro ekunze ane hunyoro hwakawanda. Maresini aya anoita basa rakanaka kumapaneru, izvo zvinoita kuti akwanise kudhura zvakanyanya zvinhu zvakabikwa. Maresini aya ndiwo anonyanya kushandiswa mukugadzira zvinhu zvekuvaka.
Mashandisirwo: Matanda ekugadzira mapuranga ane laminated veneer (LVL), particleboard, fiberboard ine density yepakati (MDF), plywood.
Maresini eMelamine urea-formaldehyde anowanikwa mumhando dzakasiyana dzemelamine kuti agutse zvinodiwa nevatengi, uye zvigadzirwa zvinogona kugadziriswa zvinoenderana nezvinodiwa nevatengi.
1. Kugadzira fenicha yemapuranga: Urea-formaldehyde resin powder inogona kushandiswa kubatanidza matanda, plywood, pasi pemapuranga nedzimwe fenicha dzemapuranga. Ine simba guru rekubatanidza uye inodzivirira kupisa, uye inogona kupa simba rekubatanidza rinogara kwenguva refu.
2. Indasitiri yekugadzira mapepa: Urea-formaldehyde resin powder inogona kushandiswa semushonga wekusimbisa pulp yekugadzira mapepa kuti iwedzere kusimba uye kuramba mvura kwepepa. Inogona kuumba hukama hwakasimba pakati pemafiber uye kuwedzera simba rekusimba uye kugara kwenguva refu kwepepa.
3. Zvinhu zvinodzivirira moto: Urea-formaldehyde resin powder inogona kusanganiswa nezvimwe zvinhu kuti igadzire machira anochengetedza moto uye manamatidziro anochengetedza moto. Izvi zvinhu zvinodzivirira moto zvinoshandiswa zvakanyanya mumidziyo yemagetsi, kuvaka, uye kutakura kuti zvidzivirire moto.
4. Indasitiri yekupenda: Urea-formaldehyde resin powder inogona kushandiswa kugadzira machira anodzivirira kupisa zvakanaka uye anodzivirira mamiriro ekunze. Machira aya anodzivirira kukwenya zvakanaka uye anodzivirira makemikari uye anoshandiswa zvakanyanya mumotokari, kuvaka nedzimwe nzvimbo.
5. Indasitiri yekugadzira machira: Upfu hweresin hweUrea-formaldehyde hunoshandiswawo muindasitiri yekugadzira machira. Hunogona kushandiswa kugadzira manamatiro akasiyana-siyana emachira, akadai sesiriki, machira emvere dzemakwai, nezvimwewo. Jira rakabatanidzwa neupfu hweresin hweurea-formaldehyde hune simba rakasimba rekudzivirira mvura uye hunogara kwenguva refu, uye hahuna kuomarara kana kukanganisika. Pamusoro pezvo, upfu hweresin hweurea-formaldehyde hunogonawo kushandiswa kugadzira zvinhu zvakasiyana-siyana zvinodzivirira mvura mumachira, zvinhu zvinodzivirira makwinya, nezvimwewo, zvichiita kuti jira rive rakanaka uye rinoshanda.
6. Namatira: Upfu hweresin yeUrea-formaldehyde hunogona kushandiswa senamatira yekubatanidza simbi, girazi, ceramics nezvimwe zvinhu. Hunodzivirira mvura zvakanaka uye hunodzivirira makemikari uye hwakakodzera kushandiswa kwakasiyana-siyana kwekubatanidza maindasitiri.
Muchidimbu, upfu hwe resin hwe urea-formaldehyde igumbeze remhando yepamusoro rine simba rakasimba uye rinodzivirira mvura. Rinoshandiswa zvakanyanya mukubatanidza zvinhu zvakaita sehuni, zvigadzirwa zvepepa, uye machira. Pamusoro pezvo, upfu hwe resin hwe urea-formaldehyde hunogonawo kushandiswa kugadzira zvinhu zvinokwesha, zvinodzivirira kupisa, zvinodzivirira ngura, nezvimwewo, uye hune mashandisirwo akasiyana-siyana uye mikana yekushandisa.
