Polyether polyurethane acrylate yemapuranga epurasitiki

Chigadzirwa Code: ZC6202

Chigadzirwa ZC6202 chigadzirwa chemhando yekambani.Zita rayo remakemikari inonzi polyether polyurethane acrylate.Imvura isina ruvara kana yero inoonekera uye yakanaka kuchinjika uye kunamatira.Inonyanya kushandiswa pepa, plastiki coating uye huni adhesion primer.Inonhuhwirira polyurethane acrylate

Wedzera polyether (polyester) diol uye polymerization inhibitor mune ina port flask ine inomutsa muchina, thermometer uye condenser chubhu, fambisa zvakaenzana, wobva wawedzera TDI, simudza tembiricha kusvika 70-80 ℃ kuita kwemaawa 1.5, tarisa kukosha kweNCO, wobva wawedzera hydroxyethyl acrylate (hydroxypropyl acrylate), wedzera catalyst, enderera mberi nekuita kwemaawa 3, uye ona kuti NCO inokosha yakaenzana ne 0. The viscosity yearomatic polyurethane acrylate yakayerwa nesampling, uye kushanda kwekunhuhwirira kwepolyurethane acrylate kwakaedzwa. nekuwedzera 3% - 4% photoinitiato.Ndapota chengetai nzvimbo inotonhorera kana yakaoma, uye dzivirirai zuva nekupisa;Tembiricha yekuchengeta haipfuuri 40 ºC, mamiriro ekuchengetedza pasi pemamiriro enguva dzose kwemwedzi mitanhatu.

Yakatangwa ne polyethylene glycol (PEG, MW 1000) ε- Caprolactone ( ε- Chikamu chakapfava chepolyether ester block copolymer diol (pCEC) chakagadzirirwa nekuvhurwa kwemhete, yakaitwa ne diisocyanate (toluene diisocyanate kana diphenylmethane diisocyanate ipapo, memethan diisocyanate, memethan diisocyanate ipapo) yakaporeswa kuti iwane polyether ester polyurethane acrylate material (PUA) Kuumbwa uye chimiro chePUA zvakaratidzwa Zvigumisiro zvinoratidza kuti kuwedzera kwePCL chikamu kunogona kuvandudza crystallinity yezvinhu zvePUA, asi kuderedza kunyura kwemvura uye kuparara kwehuwandu. kupfuura iyo yePUA Pcec2000-tdi zvinhu zvine yakanakisa hydrophilicity uye kushatisa kuita.Kunyura kwemvura kwakakwira kusvika 65.24% mumaawa makumi manomwe nemaviri uye inogona kuderedzwa zvachose mumhinduro ye enzyme mukati memavhiki gumi nerimwe Rudzi urwu rwePUA zvinhu zvine mukana wekushandiswa mune tishu engineering zvinhu.
