Sulfonated Melamine Formaldehyde ResinNā waiwai kemika:
ʻAʻole hiki ke puhi ʻia, kūpaʻa i ka lumi wela.He alkaline palupalu ka wai wai (pH=8), a hiki ke hana i ka paʻakai melamine me ka waikawa hydrochloric, ka waikawa sulfuric, ka waikawa nitric, ka waikawa acetic, ka waikawa oxalic, a me nā mea ʻē aʻe. , a i loko o nā kūlana acidic iki (pH=5.5-6.5) condensation me nā methyl derivatives e hana i nā resins.Ma hope o ka hydrolysis e ka waika ikaika a i ʻole ka hopena aqueous base ikaika, ua hoʻololi mālie ʻia ka pūʻulu amine e ka hui hydroxyl, hana mua i ka melamine, a laila hoʻohui hou i ka hydrolysis melamine monoamides, i ka hopena melamine.
Hoʻohana ʻia ka Sulfonated Melamine Formaldehyde Resin:
ʻO ka sulfonated melamine formaldehyde resin water reducer no ka wai-soluble polymer resin, colorless, maikaʻi thermal stability, i ka hoʻohana ʻana i ka hui ʻana, maikaʻi ka hoʻopuehu ʻana o ka sima, kiʻekiʻe o ka wai hoʻohaʻahaʻa ʻana, nui ka hopena ikaika mua, ʻaʻole pili i ka pā. hoʻonohonoho manawa a me ke kinoea maʻiʻo.ʻO ka melamine formaldehyde resin ke ʻano o ka wai hoʻohaʻahaʻa wai hoʻohaʻahaʻa wai kiʻekiʻe, ma ka pae dosage, hiki i ka hoʻemi ʻana o ka wai ke piʻi i 15% ~ 25%, ʻoi aku ka maikaʻi o ka lōʻihi o ke konima.
Ma muli o ka hoʻohui ʻana o ka ea entraining, ʻo ka koneki i hoʻohui ʻia me kēia huahana he mau waiwai impervious maikaʻi a me ka hau.ʻAʻole i loko o ka paʻakai chlorine a ʻaʻole e ʻino i ka pahu kila.Ua ʻike ʻia ka hopena ikaika mua, a ua hoʻonui nui ʻia ka ikaika hope.Hiki ke hoʻonui ʻia ka ikaika o 3D a me 7d e 20% ~ 25% i hoʻohālikelike ʻia me ka benchmark concrete, a hiki i ka ikaika o 28d ke hiki i 120% ~ 135% i hoʻohālikelike ʻia me ka benchmark concrete.ʻO ka melamine formaldehyde resin ka mea hoʻohaʻahaʻa wai kūpono no ka ʻenehana a me ka ʻenehana hana kīwila, precast, cast-in-place, ka ikaika mua, ka ikaika kiʻekiʻe, ka ikaika kiʻekiʻe kiʻekiʻe, ka hoʻomaʻamaʻa ʻana i ka mahu, ka ʻenekini hoʻoheheʻe super impermeable.
Eia kekahi, hiki ke hoʻohana ʻia no nā huahana gypsum, nā huahana sima kala a me nā pahu refractory a me nā papahana kūikawā ʻē aʻe.
FAQs
Q1: No ke aha wau e koho ai i kāu hui?
A: Loaʻa iā mākou kā mākou hale hana ponoʻī a me nā ʻenekini hale hana.Hana ʻia kā mākou huahana a pau i loko o kahi hale hana, no laila hiki ke hōʻoia ʻia ka maikaʻi a me ka palekana;loaʻa iā mākou kahi hui R&D ʻoihana, hui hana a me nā hui kūʻai;hiki iā mākou ke hāʻawi i nā lawelawe maikaʻi ma ke kumukūʻai hoʻokūkū.
Q2: He aha nā huahana i loaʻa iā mākou?
A: Hana nui mākou a kūʻai aku iā Cpolynaphthalene sulfonate, sodium gluconate, polycarboxylate, lignosulfonate, etc.
Q3: Pehea e hōʻoia ai i ka maikaʻi o ka huahana ma mua o ke kau ʻana i kahi kauoha?
A: Hiki ke hāʻawi ʻia nā laʻana, a loaʻa iā mākou kahi hōʻike hoʻāʻo i hoʻopuka ʻia e kahi ʻoihana hoʻāʻo ʻekolu ʻaoʻao.
Q4: He aha ka palena palena liʻiliʻi no nā huahana OEM / ODM?
A: Hiki iā mākou ke hana i nā lepili no ʻoe e like me nā huahana āu e pono ai.E ʻoluʻolu e hoʻokaʻaʻike mai iā mākou e holo mālie kāu brand.
Q5: He aha ka manawa hāʻawi manawa / ala?
A: Hoʻouna pinepine mākou i nā waiwai i loko o 5-10 mau lā hana ma hope o kāu hana ʻana i ka uku.Hiki iā mākou ke hōʻike ma ka lewa, ma ke kai, hiki iā ʻoe ke koho i kāu mea lawe ukana.
Q6: Hāʻawi anei ʻoe i ka lawelawe ma hope o ke kūʻai aku?
A: Hāʻawi mākou i ka lawelawe 24 * 7.Hiki iā mākou ke kamaʻilio ma o ka leka uila, skype, whatsapp, kelepona a i ʻole kekahi ala āu e ʻike ai.
