Sulfonatedmelaminaformaldehyderesinua kapaia hemelamine resin, i ʻike ʻia ʻomelamine formaldehyde resina i ʻolemelamine resin.He pūhui apo triazine koʻikoʻi.Melamine resinHe kūpaʻa maikaʻi ka wai, ka pale ʻana i ka wā kahiko, ka pale ahi, ka pale wela, ka pale kemika a me nā waiwai insulation, a hiki ke hoʻohana ʻia i ka hana ʻana i nā pūhui hoʻoheheʻe ʻia (nā papa ʻaina i kēlā me kēia lā a me nā mea uila), nā panela lāʻau (plywood, laminate flooring a me laminated plastic. nā papa) ) a me ka plastic foam, a pēlā aku. melamine resinhoʻohana nui ʻia e like me nā uhi, nā lāʻau adhesives, nā mea hoʻohui keʻa pena, nā mea hoʻopau lole lole fiber, nā mea ikaika wai pepa a me nā mea hoʻemi wai sima.

Melamine resinLoaʻa nā noi nui penei:

1. Ke noi ma ka ʻoihana ʻili:

Ma ka ʻoihana ʻili,melamine resinhe mea maʻamau i hoʻohana ʻia ma mua o ka tanning, retanning a me ka hoʻopiha piha ʻana, i waena o ka trimethylolmelamine resinʻo ia ka resin amino i hoʻohana nui ʻia.ʻO ka resin amino he hana tanning e like me ka aldehyde tanning: ke komo ka prepolymer i loko o ka ʻili, a i ka emi ʻana o ka waiwai pH, hoʻopili koke ka prepolymer i loko o kahi mole me kahi nui o ka ʻili, a me ka mea hana -NHCH 2 OH a kolagen i loko o ka mole ke hele ma.Hoʻopili ʻia nā hui amino ma ke kaulahao peptide e hana i kahi ʻōnaehana cross-linking covalent e hoʻokō i ke kumu o ka tanning.I ka manawa like, he hopena hoʻopiha ka resin amino.Ua hoʻohana ʻo Braum, Aloysins a me nā mea ʻē aʻe i ka GPS, IR, 1H-NMR, 13C-NMR a me nā ʻano ʻike ʻē aʻe, a ʻike ʻia aia kēia resin i ka tanning a me ka hoʻopiha ʻana i nā waiwai, a hiki ke hoʻopiha ʻia i ka nui ma waena o nā kolagen fiber o ka ʻili e hoʻopololei i ke kino ʻili.Ka hopena.Melamine resinHoʻohana ʻia ka tanning agent i ka hoʻopaʻa ʻana i ka ʻili māmā chrome-tanned e hana i ka ʻili i hoʻopau ʻia i ka palaoa maikaʻi, piha i nā iwi, ʻike ʻia ka mānoanoa, ka hopena keʻokeʻo maikaʻi a me ka wikiwiki māmā.A he kūpono maikaʻi ia me nā mea hana tanning ʻē aʻe.Hoʻohana ʻia i ka hui pū ʻana me nā mea kanu tanning mea kanu, hiki iā ia ke hoʻoikaika i ke komo ʻana a me ka absorption o nā mea kanu tanning mea kanu, a hoʻonui i ka pale abrasion a me ka pale ʻana o ka ʻili.Inā hoʻohana ʻia no ka hoʻopaʻa ʻana i ka suede, maikaʻi ka hopena hoʻokiʻekiʻe.

2. Ke noi ma ka ʻoihana pepa:

ʻO ke kumu a me nā hiʻohiʻona hana o ka hoʻohana ʻia ʻana ma ke ʻano he mea hoʻoikaika wai a me ka wai repellant.No ka meamelamine formaldehyde resinloaʻa i ka methylol, hiki iā ia ke hana i kahi ʻano etherified ma waena o nā pūʻulu fiber.ʻO kēia hoʻopili keʻa ma waena o nā molekala like ʻole e hoʻopuka i ka pale wai a hana i ka pepa pepa.No ka hoʻokō ʻana i ka hopena o ka ikaika moisturizing, hoʻohana nui ʻia ʻo ia ma ke ʻano he mea hoʻoikaika ikaika a me ka wai repellant i ka ʻoihana pepa.Hoʻohana nui ʻia ka Trimethylol melamine i ka ʻoihana pepa, akā no ka mea ʻaʻole kūpono kona kūpaʻa, ka wai a me ka formaldehyde manuahi, a he hopena maikaʻi ʻole ia i ka keʻokeʻo a me ka lōʻihi o ka pepa, ua hoʻohana nui ʻia ka melamine i hoʻololi ʻia i kēia manawa.resin.

3. Hoʻohana ʻia e like me ka dispersant seramika a me ka sima:

Melamine formaldehyde resinʻO ka sulfonate kahi surfactant anionic maikaʻi me ka hana ʻili a me nā waiwai waiwai ʻē aʻe.Hoʻohana pinepine ʻia e like me ka dispersant kiʻekiʻe a i ʻole ka mea hoʻohaʻahaʻa wai i nā seramika, sima a me nā ʻāpana ma ka home a ma waho.ʻO ke ʻano o kāna hana ka mea nui: ʻo kēia ʻano mea hoʻohaʻahaʻa wai i nā hana o ka adsorption, dispersion a me ka lubrication, no laila hiki ke hoʻomaikaʻi ʻia ka hana o ke konima ma o ka hoʻohana ʻana i ka wai liʻiliʻi, i mea e hoʻokō ai i ke kumu o ka hōʻemi wai.Ma muli o ka emi ʻana o ka ratio hui ʻana o ka wai, ua hoʻemi ʻia nā pores i loko o ka pahu, e hoʻonui i ka sima a hoʻonui i ka ikaika, hiki ke hoʻemi i ka nui o ka sima.Ma muli o ka hoʻokomo ʻana o ka mea hoʻohaʻahaʻa wai, ua lohi ka ulu ʻana o nā huahana hydration cement, a ʻoi aku ka paʻakikī o ka ʻōnaehana sulfonated concrete, i mea e pono ai ka hoʻonui ʻana i ka ikaika lōʻihi o ka ʻuala.

4. Hoʻohana ʻia e like me ka lāʻau hoʻopili:

Ma ka oihana laau,sulfonatedmelaminaformaldehyderesinhoʻohana nui ʻia e like me nā mea hoʻopili.Ma muli o kāna hana kemika kiʻekiʻe, ke komo ʻo ia i loko o nā huahana lāʻau, ʻoi aku ka wikiwiki o ka hoʻopili ʻana a me ka paʻakikī paʻakikī, a hiki ke hoʻopaʻa ʻia i ka wela a paʻakikī paha i ka lumi wela me ka ʻole o nā mea paʻakikī ʻē aʻe.Ma muli o kona kūpaʻa wela maikaʻi, ke kūpaʻa wai a me ke kūpaʻa kemika, hoʻohana nui ʻia ia i nā paneli kumu lāʻau, lāʻau, kūkulu hale, pepa pepa a me nā māla ʻē aʻe.ʻO ka manaʻo o kēia kahua pehea e lanakila ai i ke ʻano o ka pohā a loaʻamelamine formaldehyde resinme ka hoʻololi kūpono.ʻO ka hopena o kēia manawa e hoʻohui i ka waiʻona polyvinyl, no ka mea hiki iā ia ke hana me ka formaldehyde e hoʻohua i ka polyvinyl acetal, i hoʻohele like ʻia i loko o ka resin, i mea e pale ai i nā molekole heterocyclic nitrogen ʻekolu i loko o nā molekala resin MF mai ka hoʻokokoke ʻana, pāʻani i kahi hopena paʻakikī a pale i ka hakihaki.

5. Hoʻohana ʻia ma ke ʻano he mea paʻi lole a me ka mea hoʻopau wai:

Ma ka hana lole lole,sulfonatedmelaminaformaldehyderesina ʻo kāna mau mea hoʻoheheʻe he mau mea waiwai nui ia no ka hoʻomākaukau ʻana i ka paʻi lole, ka waihoʻoluʻu a me nā mea hoʻopau.Hoʻohana nui ʻia kāna ʻano hana ma ke ʻano he mea hoʻololi i ka ʻili a me nā mea hoʻohui no nā lole, no laila e hoʻomaikaʻi ai i ka anti-shrinkage, anti-wrinkle a me ka holoi wai wai o nā lole pulupulu.Eia nō naʻe, ma muli o ka paʻa ʻole o ka mālama ʻana, ka manaʻo lima ʻino a me ka maʻalahi o ka lawe ʻana i ka chlorine a me ka melemele ʻana o ka lole ma hope o ka noi ʻana, ua nui aʻe nā noiʻi i hana ʻia ma kāna hoʻololi.I kēia manawa, etherified ka methanolmelamine resinhoʻohana ʻia, a hoʻohui ʻia nā mea hoʻololi formaldehyde e like me ka cyclic vinylidene urea a me ka borax no ka loaʻa ʻana o kahi hoʻololi.melamine formaldehyde resinmea hoʻopau me ka ultra-haʻahaʻa aldehyde a me ke kūpaʻa kiʻekiʻe.Hoʻohana ʻia ka resin i hoʻololi ʻia no ka anti-shrinkage a me ka anti-wrinkle o ka poplin bleached Finishing, yellowing and chlorine loss are improved, and washing resistance is also better.Eia kekahi, ʻo ka manawa mālama o ka mea hoʻopau hoʻopau ʻo 210-365 d, ʻo ka ʻike formaldehyde manuahi he 0.3%, a ʻo ka ʻike paʻa ma kahi o 40%.
