I-Sulfonated Melamine Formaldehyde Resin Powder White CAS 9003-08-1
Inkcazelo emfutshane:
I-Sulfonated melamine formaldehyde (melamine), eyaziwa ngokuba yi-melamine, i-protein essence, i-molecular formula yi-C3H6N6, i-IUPAC ebizwa ngokuthi "1,3, 5-triazine-2,4, 6-triamine", yi-triazine-containing heterocyclic organic compounds njengekhemikhali. iimpahla ezingekasilwa.Yikristale emhlophe ye-monoclinic, phantse ayinavumba, inyibilika kancinane emanzini (kwiqondo lobushushu begumbi 3.1g/L), i-soluble kwi-methanol, i-formaldehyde, i-acetic acid, i-glycol eshushu, i-glycerin, i-pyridine, njl., ayinyibiliki kwi-acetone, i-ether, eyingozi. kumzimba womntu, ayinakusetyenziswa ekwenzeni ukutya okanye izongezo zokutya.

I-Sulfonated Melamine Formaldehyde ResinIinkcazelo ngeMichiza:
Ukungatsha, kuzinzile kwiqondo lokushisa.Isisombululo samanzi sinobuthakathaka bealkaline (pH = 8), kwaye singenza ityuwa ye-melamine kunye ne-hydrochloric acid, i-sulfuric acid, i-nitric acid, i-acetic acid, i-oxalic acid, njl. Kwiimeko ezingathathi hlangothi okanye ezincinci ze-alkaline, ukudibanisa kunye ne-formaldehyde ukwenza i-methyl melamine eyahlukeneyo. , kunye neemeko ze-acidic encinci (pH = 5.5-6.5) ukuxiliswa kunye ne-methyl derivatives ukwenza i-resins.Emva kwe-hydrolysis nge-asidi eyomeleleyo okanye isisombululo esinamandla se-aqueous, iqela le-amine ngokuthe ngcembe lithatyathelwa indawo liqela le-hydroxyl, kuqala lenze i-melamine, emva koko i-hydrolysis yenze i-melamine monoamides, ekugqibeleni yenze i-melamine.
Ukusetyenziswa kweSulfonated Melamine Formaldehyde Resin:
I-Sulfonated melamine formaldehyde resin water reducer ye-water-soluble polymer resin, engenambala, ukuzinza okulungileyo kwe-thermal, ekusebenziseni umxube wekhonkrithi, ukusasazwa kakuhle kwesamente, izinga eliphezulu lokunciphisa amanzi, umphumo wamandla okuqala ubalulekile, ngokusisiseko awuchaphazeli ikhonkrithi. ixesha lokumisela kunye nomxholo wegesi.Uhlobo lwe-resin ye-Melamine formaldehyde ye-ejenti yokunciphisa amanzi esebenzayo inqanaba lokunciphisa amanzi liphezulu, kuluhlu lwedosi, izinga lokunciphisa amanzi linokufikelela kwi-15% ~ 25%, ukuqina kwekhonkrithi kuphuculwe kakhulu.
Ngenxa yokubunjwa kwe-air entraining, ikhonkrithi eyongeziweyo kunye nale mveliso ineempawu ezintle ezingenakunqanda kunye neqhwa.Ayinayo ityuwa yeklorini kwaye ayiyi kutshabalalisa ibha yensimbi.Impembelelo yamandla okuqala yayicacile, kwaye amandla kamva anyuswa kakhulu.Amandla e-3D kunye ne-7d anokunyuswa nge-20% ~ 25% xa kuthelekiswa nekhonkrithi ye-benchmark, kwaye amandla e-28d anokufikelela kwi-120% ~ 135% xa kuthelekiswa nekhonkrithi yokulinganisa.I-Melamine formaldehyde i-resin yokunciphisa amanzi i-arhente yokunciphisa amanzi ifanelekile kubunjineli bokwakhiwa kwemizi-mveliso kunye nolwakhiwo, i-precast, i-cast-in-place, amandla okuqala, amandla aphezulu, i-concrete ephezulu yamandla aphezulu, ikhonkrithi yokunyanga umphunga, ubunjineli bekhonkrithi obungenakunyakaziswa.
Ukongeza, ingasetyenziselwa iimveliso zegypsum, iimveliso zesamente ezinombala kunye nekhonkrithi ephikisayo kunye nezinye iiprojekthi ezikhethekileyo.
