Melamine formaldehyde resin imhando itsva ye melamine resin, inogadzirwa kubva ku melamine ne formaldehyde ne polycondensation reaction. Melamine formaldehyde resin ine hunhu hwakanaka hwemuviri nehwemakanika, inodzivirira makemikari akawanda, inodzivirira kupisa uye inodzivirira mvura. Inodzivirira mvura uye inogara kwenguva refu yezvigadzirwa zvayo zviri nani pane zve urea-formaldehyde resin, saka inoshandiswa zvakanyanya mukugadzira fenicha nekushongedza zvivakwa. Nekuda kwehushamwari hwayo hwakanaka nezvakatipoteredza, melamine formaldehyde resin inoonekwa sechigadzirwa chakakodzera kutsiva urea-formaldehyde resin.
Mumakore achangopfuura, melamine formaldehyde resin yave yakanakira mhando nyowani yekunamira yehuni kugadzirwa nekuda kwekupisa kwayo kupisa, kudzivirira kwemvura uye kushomeka kwemakemikari.
Kuenzaniswa neurea-formaldehyde resin, melamine-formaldehyde resin ine zvinotevera zvakanakira: yakaderera formaldehyde yemukati, zvinoenderana nezvinodiwa zvekuchengetedzwa kwezvakatipoteredza, nyore kugadzira maitiro, kunaka kwechigadzirwa, kuita kwakagadzikana, nyore kugadzirisa uye kuumba.
Pane nzira mbiri huru dzekugadzira melamine formaldehyde resin: imwe inzira yakananga uye imwe isina kunanga nzira. Iyo yakananga nzira ndeyekusanganisa melamine uye formaldehyde, kupisa kusvika ku70 ° C, uyezve kudzora tembiricha iri pakati pe80 ° C ~ 90 ° C nekuwedzera zvinhu, kudziya, kumutsa, nezvimwewo, uye kuita kwe3 ~ 4h, ipapo melamine formaldehyde resin inogona kuwanikwa. Muchiitiko ichi, nitrogen inoshandiswa kuchengetedza formaldehyde kubva pakusunungurwa. Iyo isina kunanga nzira ndeyekusanganisa melamine uye formaldehyde uye wovawedzera kune reactor kuti uite. Sezvo melamine ne formaldehyde zviri zviviri zvisina simba alkaline zvinhu, iyo H + neOH- inogadzirwa panguva yekupindura inogona kuita ne CO2, H2O nemamwe magasi ari mumhepo kugadzira zvinhu zvine gasi, izvo zvakaparadzaniswa nemhepo nekuburitsa kunze kweketero, uye synthesized melamine-formaldehyde resin, inogona kuwanikwa nekuita distill.
Iyo yekubatanidza uye gluing zvimiro zve melamine-formaldehyde resins inowedzera nekuwedzera kwe melamine yemukati mune melamine-formaldehyde resins. Nekudaro, iyo yekubatanidza uye gluing zvimiro zve melamine formaldehyde resin inodzikira nekuwedzera tembiricha, nepo gluing zvimiro zvayo zvichiwedzera nekuwedzera tembiricha. Kana tembiricha ichikwira kusvika pamwero wakati, viscosity inodzikira kune imwe kukosha uye yobva yatanga kusimuka zvakare. Mukati meimwe siyana, viscosity ye melamine formaldehyde resin inoderera nekuwedzera kwe melamine content. Kana ichienzaniswa neurea-formaldehyde resin, kupisa kwayo kupisa, kushomeka kwemvura uye kushomeka kwemakemikari kuri nani pane iyo urea-formaldehyde resin.
Resin yeMelamine formaldehyde inonyanya kushandiswa mukugadzira mapuranga eplywood, joinery, plywood nezvimwewo, uye inogona kushandiswa sechikamu chebhodhi rekugadzira remapepa efirimu rakaiswa mukati. Pamusoro pezvo, inogona kushandiswawo kune marudzi ese emabhodhi akagadzirwa nevanhu akashongedzwa nepepa rakaiswa mukati uye mabhodhi ezvimedu, mafiberboard epakati nepakati, mabhodhi etambo akashongedzwa nepepa refirimu rakaiswa mukati. Mubasa rekushongedza zvivakwa, resin yemelamine formaldehyde ine simba rakanaka rekudzivirira mvura uye kugara kwenguva refu, uye inogona kushandiswa mumhando dzese dzezvinhu zvekushongedza zvemukati uye zvekushongedza zvekunze. Resin yeMelamine formaldehyde inogonawo kushandiswa mukugadzira plywood inodzivirira kupisa, bepa remelamine (rinonzi bepa remelamine) uye bepa rakaiswa mukati memelamine. Inogona kushandiswa sechikamu chemapuranga ekugadzira epepa akaiswa mukati, uye zvakare sezvinhu zvekushongedza zvemukati zvakaita sebhodhi rezvimedu, bepa repakati nepakati uye bhodhi rakashongedzwa nebepa rakaiswa mukati.
Melamine formaldehyde resin inogona kushandiswa kugadzira fenicha uye zvigadzirwa zvehuni, pamwe nekuvaka zvekushongedza zvinhu zvakaita seveneer, pendi, plywood, blockboard, uye zvakare mabhodhi ekugadzira. Melamine formaldehyde resin inogona kushandiswa sezvivakwa zvekuvaka uye zvemukati zvekushongedza zvinhu, uye zvakare inogona kushandiswa sezvikafu zvekurongedza zvinhu. Nekuti melamine formaldehyde resin ine yakanakisa yemuviri uye yemagetsi zvivakwa uye makemikari kuramba, inoshandiswa zvakanyanya mukugadzira plywood uye blockboard. Mabhenefiti makuru e melamine-formaldehyde resin yakanaka yemuviri uye michina zvivakwa, yakanaka kupisa uye kudzivirira mvura, uye inowanzoshandiswa mukugadzira yepakati density fiberboard uye particleboard.
