Sulfonatedmelamineformaldehyderesininodaidzwa kutimelamine resin, inozivikanwawo semelamine formaldehyde resinkanamelamine resin.Iyo yakakosha triazine ring compound.Melamine resinine yakanakisa kudzivirira kwemvura, kuramba kuchembera, kudzoreredza moto, kusapisa kupisa, makemikari kuramba uye zvivakwa zvekudzivirira, uye inogona kushandiswa mukugadzira michina yekuumba (mazuva ese tableware nemidziyo yemagetsi), mapaneru ane huni (plywood, laminate flooring uye laminated plastic. mapuranga)) uye purasitiki yefuro, nezvimwewo. melamine resinInoshandiswawo zvakanyanya semapendi, matanda anonamira, pendi yemuchinjikwa-inobatanidza maajenti, fiber textile finishing agents, bepa wet simba maajenti uye simende zvinoderedza mvura.

Melamine resinine maapplication makuru anotevera:

1. Kushandiswa muindasitiri yematehwe:

Muindasitiri yematehwe,melamine resininowanzoshandiswa pre-tanning, retanning uye kuzadza resin, pakati payo trimethylolmelamine resinndiyo inonyanya kushandiswa amino resin.Amino resin ine maitiro ekupisa akafanana neaya ealdehyde tanning: iyo prepolymer inopinda muganda, uye kana pH yakaderera ichiderera, iyo prepolymer inongoerekana yapinda mumorekuru ine imwe saizi muganda, uye inoshanda -NHCH 2 OH uye collagen mumorekuru inopfuudzwa.Iwo mapoka emaamino pane peptide cheni anodzorwa kuti aite covalent cross-linking system kuzadzisa chinangwa chekupisa.Panguva imwecheteyo, iyo amino resin ine mhedzisiro yekuzadza.Braum, Aloysins nevamwe vakashandisa GPS, IR, 1H-NMR, 13C-NMR nedzimwe nzira dzekuona, uye vakaona kuti resin iyi ine zvese zvekupisa nekuzadza zvivakwa, uye inogona kuzadzwa muhuwandu hukuru pakati peiyo collagen fiber yedehwe kusvika. ita kuti muviri wedehwe uwedzere.Mhedzisiro.Melamine resinTanning agent inoshandiswa mukudzoreredza chrome-tanned light dehwe kuti ganda rakapedzwa rive rakatsetseka, rizere nemapfupa, kukora kuri pachena, kuchena kwakanaka uye kumhanyisa kwechiedza.Uye ine kuenderana kwakanaka nemamwe maajenti ekupisa.Inoshandiswa pamwe chete nemishonga yekuchenesa miriwo, inogona kukurudzira kupinda uye kunyura kwemuriwo wekupisa, uye kuwedzera abrasion kuramba uye kuramba kwemamiriro ekunze kweganda.Kana yakashandiswa kudzoreredza suede, iyo yekusimudza mhedzisiro yakanaka.

2. Kushanda muindasitiri yemapepa:

Nheyo uye maitiro ekuita ekushandiswa seyakanyorova inosimbisa agent uye inodzivirira mvura.Nokuti iyomelamine formaldehyde resinine methylol, inogona kugadzira etherified chimiro pakati pemasumbu efiber.Uku kuyambuka-kubatanidza pakati pemamorekuru akasiyana kunoburitsa kusamira kwemvura uye kunoita bepa bepa.Kuti uwane mhedzisiro yekunyorovesa simba, inonyanya kushandiswa seyakanyorova inosimbisa mumiriri uye inodzivirira mvura muindasitiri yemapepa.Trimethylol melamine inonyanya kushandiswa muindasitiri yemapepa, asi nekuda kwekugadzikana kwayo, kunyungudika kwemvura uye yemahara formaldehyde zvirimo hazvina kunaka, uye zvine mhedzisiro yekuchena uye kusimba kwepepa, iyo yakagadziridzwa melamine inoshandiswa zvakanyanya parizvino.resin.

3. Inoshandiswa seceramic uye simende dispersant:

Melamine formaldehyde resinsulfonate yakanaka anionic surfactant ine chiitiko chepamusoro uye zvimwe zvakakosha zvinhu.Inowanzo shandiswa seyepamusoro-inoshanda dispersant kana mvura inoderedza mumakeramiki, simende uye kongiri kumba nekune dzimwe nyika.Iyo nzira yekuita kwayo inonyanya: iyi mhando yemvura inoderedza mumiriri ine mabasa ekushambadza, kupararira uye lubrication, saka kushanda kwekongiri kunogona kuvandudzwa nekushandisa mvura shoma, kuitira kuti uwane chinangwa chekudzikisa mvura.Pamusana pekuderera kwehuwandu hwekusanganiswa kwemvura, pores mukrete inoderedzwa, zvichiita kuti simiti iwedzere uye kuwedzera simba, izvo zvinogonawo kuderedza kuwanda kwesamende.Nekuda kwekupinda kweiyo mvura inoderedza agent, kukura kwe simenti hydration zvigadzirwa zvinononoka, uye iyo sulfonated kongiri network yakawedzera dense, iyo inobatsira pakuwedzera kwesimba renguva refu rekongiri.

4. Inoshandiswa sehuni yekunamatira:

Muindasitiri yehuni,sulfonatedmelamineformaldehyderesinanonyanya kushandiswa seanonamira.Nekuda kwekuita kwayo kwemakemikari akakwira, kana ichipinda muzvigadzirwa zvehuni, kuchinjika-kubatanidza uye kuomesa kukurumidza kunokurumidza, uye inogona kuomeswa nemafuta kana kuomeswa pakupisa kwekamuri pasina zvimwe zvinoomesa, nekudaro zvichigadzira hukama.Nekuda kwekugadzikana kwayo kwakanaka kwekupisa, kushorwa kwemvura uye kushomeka kwemakemikari, inoshandiswa zvakanyanya mumapuranga-based panels, huni, kuvaka, kurongedza mapepa nemimwe minda.Chinangwa chemunda uyu ndechekuti ungakunda sei chiitiko chekutsemuka uye kuwanamelamine formaldehyde resinnekugadzikana kuri pakati nepakati.Mhinduro yazvino ndeyekuwedzera polyvinyl doro, nekuti inogona kuita ne formaldehyde kugadzira polyvinyl acetal, iyo yakagovaniswa muresin, kuitira kuvhara matatu nitrogen heterocyclic mamorekuru muMF resin mamorekuru kuti asaswedere, tamba inoomesa uye kudzivirira kutsemuka.

5. Inoshandiswa semachira ekudhinda uye kudhaya kupedza agent:

Muindasitiri yemachira,sulfonatedmelamineformaldehyderesinuye zvigadzirwa zvayo zvakakosha zvigadzirwa zvekugadzirira kudhinda machira, kudhaya uye kupedza vamiririri.Maitiro ayo ekuita anonyanya kushandiswa seyepamusoro pedhifita uye yekubatanidza mumiriri wemachira, nekudaro inovandudza anti-shrinkage, anti-wrinkle uye mvura-yekugeza zvimiro zvemachira ekotoni.Nekudaro, nekuda kwekusagadzikana kwekuchengetedza kugadzikana, hutsinye hwekunzwa kwemaoko uye kunyura nyore kweklorini uye kutsvuka kwejira mushure mekushandiswa, tsvakiridzo dzakawanda dzakaitwa pakugadziridzwa kwayo.Panguva ino, methanol etherifiedmelamine resininoshandiswa, uye formaldehyde modifiers senge cyclic vinylidene urea uye borax inowedzerwa kuti iwane yakagadziridzwa.melamine formaldehyde resinkupedza mumiririri ane ultra-low aldehyde uye yakakwirira kugadzikana.Iyo yakagadziridzwa resin inoshandiswa kune anti-shrinkage uye anti-wrinkle ye bleached poplin Kupedza, kutsvuka uye kurasikirwa kweklorini kunovandudzwa, uye kuramba kwekugeza kuri nani zvakare.Uyezve, nguva yekuchengetedza yemumiriri wekupedzisa ndeye 210-365 d, iyo yemahara formaldehyde yemukati ndeye 0.3%, uye yakasimba yemukati inenge 40%.
