Hoʻokomo huahana a me nā hiʻohiʻona

ʻO N-hydroxymethylacrylamide kahi pauka keʻokeʻo keʻokeʻo.ʻO 1.185 (23/4 ℃) ka mānoanoa pili, a ʻo ka helu heheʻe he 75 ℃.I ka laulaha hydrophilic hiki ke hoʻoheheʻe 'ia, no ka momonaʻakika esters, acrylicʻakika a me ka methylacrylate, mehana no hoi i nui solubility, akā, aneane insoluble i loko o hydrophobic solvents e like me hydrocarbons, halogenated hydrocarbons.Hiki ke ho'ohana 'ia ma ke 'ano he cross-linking agent, ho'ohana nui 'ia ma ka fiber modified resin, processing dye, plastic binder, soil stabilizer, etc. ʻO ka mole o ka huahana he paʻa pālua i hui pū ʻia me ka hui carbonyl a me ka hui hydroxyl methyl reactive.He monomer cross-linking i hoʻohana nui ʻia no ka hoʻololi ʻana i ka fiber, ka hana resin, nā adhesives, ka pepa, ka ʻili, ka mea lapaʻau ʻili metala, a hiki ke hoʻohana ʻia e like me ka hoʻololi ʻana i ka lepo.

hoʻohana

He mea waiwai ia no ka hana ʻana i ka resin thermosetting, ka uhi ʻana i ka epoxy resin māmā, ka uhi ʻaila a me ka uhi maloʻo.Hoʻohana ʻia kāna emulsion copolymerization no ka hoʻopau ʻana i ka fiber, ka lole, ka ʻili a me ka uhi pepa.Hoʻohana ʻia ia ma ke ʻano he mea hoʻopili no ka lāʻau, metala, etc.
Hoʻohana ʻia ma ke ʻano he monomer i hoʻopili ʻia no ka emulsion acrylic.ʻO ke ʻano o ka paʻa paʻa paʻa emulsion emulsion i loko o ka hui carboxyl he L% ~ 2% o ka nui o ka monomer, inā ʻoi aku ma mua o 3%, e hoʻemi nui ʻia ka viscosity mua.No ka emulsion adhesive me ka hui carboxyl, ʻaʻole i ʻoi aku ka nui o ka nui ma mua o 5%.ʻOi aku ka kiʻekiʻe o ka wela o ka hopena crosslinking MMAM wale nō, ma ke ʻano he 120 ~ 170 ℃, me ka hoʻohui ʻana i kahi catalyst ʻano proton hiki ke hōʻemi i ka mahana crosslinking.Hiki i ka ʻakika Acrylic (AA) ke hāʻawi i nā protons hydrogen, a me ka copolymerization me ka acrylate, no laila e hana ʻo MMAM i kahi hui crosslinking hui me AA, ʻoi aku ka maikaʻi o ka nui o 3:2.Hiki i ka cross-linker HA ke pani i ka N-hydroxymethylacrylamide a ʻaʻohe formaldehyde.

pūʻolo a me ka lawe ʻana

B. Hiki ke hoʻohana ʻia kēia huahana, 25KG，BAGS
C. E kūʻai i sila ma kahi anuanu, maloʻo a me ka makani i loko o ka hale.Pono e hoʻopaʻa paʻa ʻia nā pahu ma hope o kēlā me kēia hoʻohana ma mua o ka hoʻohana ʻana.
D. Pono e hoʻopaʻa maikaʻi ʻia kēia huahana i ka wā o ka lawe ʻana i mea e pale ai i ka makū, ka alkali ikaika a me ka waikawa, ka ua a me nā mea haumia ʻē aʻe mai ka hui ʻana.
