Ko te Melamine Formaldehyde Resin Ma te Paura CAS 9003-08-1
Whakaahuatanga Poto:
Ko te melamine formaldehyde (melamine), e mohiotia ana ko te melamine, te mauri pūmua, ko te tātai rāpoi ko C3H6N6, ko te IUPAC te ingoa "1,3, 5-triazine-2,4, 6-triamine", he triazine-kei roto i nga pūhui waro heterocyclic hei matū. rauemi mata.He karaihe monoclinic ma, tata kore kakara, paku wairewa i roto i te wai (i te 3.1g/L te pāmahana rūma), wairewa i roto i te methanol, formaldehyde, waikawa acetic, glycol wera, glycerin, pyridine, etc., insoluble in acetone, ether, kino ki te tinana o te tangata, kaore e taea te whakamahi ki te tukatuka kai, ki nga taapiri kai ranei.

Melamine Formaldehyde Resin SulfonatedĀhuatanga matū:
Kare e mura, ka mau i te pāmahana rūma.Ko te wairewa wai he kawakore (pH=8), ka taea te hanga tote melamine me te waikawa maaota, te waikawa pungatara, te waikawa nitric, te waikawa acetic, te waikawa oxalic, me etahi atu. , i roto i nga ahuatanga waikawa paku (pH=5.5-6.5) te whakamaarama me te methyl derivatives hei hanga kapia.I muri i te hauwai i te waikawa kaha, i te wairewa wai turanga kaha ranei, ka whakakapia te roopu amine e te roopu hydroxyl, tuatahi te hanga melamine, katahi ano te hydrolysis ka hanga melamine monoamides, ka mutu te hanga melamine.
Te Whakamahinga Resin Formaldehyde Sulfonated Melamine:
Ko te melamine formaldehyde kapia te whakaheke wai no te wai-wairewa polymer resin, he kore tae, he pai te waiariki, i roto i te whakamahi i te ranunga raima, te marara pai o te ciment, te tere o te whakaheke i te wai, he mea nui te kaha o te kaha, kaore e pa ki te raima. te whakarite i te wa me te ihirangi hau.Melamine formaldehyde resin momo o te pai te whakaiti i te wai kaihoko te reiti whakaiti wai he tiketike, i roto i te awhe inenga, ka taea te reiti whakaiti wai 15% ~ 25%, te mauroa o te raima tino pai ake.
Na te hanganga o te hau e uru ana, ko te raima kua tapirihia ki tenei hua he pai nga ahuatanga koretake me te haupapa.Karekau he tote maaota, ka kore e waikura te pae rino.I kitea te kaha o te kaha o mua, a ko te kaha o muri i tino piki ake.Ko te kaha o te 3D me te 7d ka taea te whakanui ake i te 20% ~ 25% ka whakatauritea ki te raima tohu, me te kaha o te 28d ka tae ki te 120% ~ 135% ka whakaritea ki te raima tohu.Ko te melamine formaldehyde resin wai-whakaiti kaihoko he pai mo te hanga ahumahi me te hanga-a-iwi, tomua, maka ki roto i te waahi, te kaha moata, te kaha teitei, te raima kaha teitei, te raima whakamaarama mamaoa, te miihini raima tino koretake.
I tua atu, ka taea hoki te whakamahi mo nga hua gypsum, hua ciment tae me te raima whakaahuru me etahi atu kaupapa motuhake.
