Imashini ya DMDEE ikora cyane ikoreshwa mu gukamura ifuro rya Polyurethane

Ishusho ya DMDEE Catalyst ikora cyane kuri Polyurethane Foam

ibisobanuro bigufi:

Dimorpholinodiethyl Ether (DMDEE) ni catalyst ya amine ikora cyane yihutisha ibikorwa bya urethane, bigatuma DMDEE iba ingenzi mu gukora ifuro rikomeye kandi rigoye, ndetse no gusiga irangi no gufunga. DMDEE igaragaza uburyo bwiza bwo guhitamo, iteza imbere inzira yo gusiga irangi nta ngaruka mbi nyinshi, ibi bikaba byemeza ko ibicuruzwa bifite ubuziranenge n'imikorere ihoraho. Kubera ko ishonga neza muri sisitemu nyinshi za polyurethane, DMDEE yongera ubushobozi bwo guhuza ibintu kandi ikagabanya igihe cyo kuyivura, yongera umusaruro w'inganda. DMDEE kandi igaragaza imihindagurikire mike kandi impumuro nke, ijyanye n'amahame akomeye y'umutekano mu nganda kandi bigatuma DMDEE iba amahitamo meza yo gukoresha polyurethane ikora neza kandi idahungabanya ibidukikije ku masoko mpuzamahanga.

Ibisobanuro

Icyiciro cy'umutungo	Ibisobanuro birambuye
Indangamuntu y'ibanze y'ibinyabutabire	Izina ry'ubutabire: Dimorpholinodiethyl Ether (DMDEE)Nimero ya CAS: 6425-39-4 Formula ya Molecular: C₁₀H₂₀N₂O₃ Uburemere bwa molekile: 216.28 g/molekile
Isura n'impumuro mbi	Ikinyabutabire kitagira ibara cyangwa umuhondo werurutse; Impumuro idakomeye, imeze nk'iya amine
Imiterere y'ingenzi y'umubiri	Aho kubira: 225–230 °CAho gushonga: -20 °C Ubucucike: 0.98 g/cm³ (kuri 20 °C) Aho ubushyuhe bugarukira: 101 °C (igikombe gifunze) Ubushyuhe: 15–20 mPa·s (kuri 25 °C) Umuvuduko w'umwuka: < 0.1 mmHg (kuri 20 °C)
Umwirondoro w'ingufu	Bivangwa n'ibintu bisanzwe bisukura ibintu (inzoga, esters, ethers, hydrocarbons);Bishongesha gato mu mazi (~1% by'uko bishonga kuri 25 °C)
Ibiranga ubutabire	Katalyst ishingiye kuri amine ya gatatu;Ihinduka ryinshi ku bikorwa bya isocyanate-hydroxyl; Ihamye mu gihe gisanzwe cyo kubika (irinde aside/base zikomeye); Ntishobora kwangiza ibyuma bisanzwe byo mu nganda (icyuma, aluminiyumu)
Umutekano n'uburozi	LD₅₀ yo mu kanwa ikaze (imbeba): ~2000 mg/kgUruhu rworoshye n'amaso birakaza iyo bikozweho Amazi adashya (aho umuriro ugera > 100 °C) Nta miterere izwi itera impinduka mu mikorere y'umubiri cyangwa kanseri
Porogaramu z'ibanze	Katalyst ya Urethane ikoreshwa mu gukaraba ifuro rya polyurethane rikomeye/rishobora koroha;Ingufu zo gusiga amavuta ku bisigazwa bya PU, kole, n'ibifunga; Ifasha mu gutunganya imyenda n'ibikoresho byo mu nzu.

Dimorpholinodiethyl Ether (DMDEE, CAS 6425-39-4)ni catalyst ya amine ifite imikorere myiza, irangwa no guhitamo kwayo ku buryo budasanzwe, kudahindagurika cyane, no guhuza neza na sisitemu za polyurethane (PU) - iyishyira mu mwanya wayo nk'inyongera y'ingenzi mu nganda zikora neza. Bitandukanye na catalyst ya amine isanzwe, DMDEE itanga kwihutisha ibikorwa bya urethane cross-linking, ikagabanya ingaruka mbi no kwemeza ko ikora neza hatabayeho kwangiza imiterere y'ibicuruzwa, ikubahiriza byimazeyo amahame mpuzamahanga y'ubwiza n'ibidukikije.

Porogaramu za DMDEE zikubiyemo inganda nyinshi zifite agaciro kanini: ni yo mpamvu ikoreshwa cyane mu gukora ifuro rya PU rikomeye kandi ryoroshye rikoreshwa mu kubaka no kwicara mu modoka, aho ryongerera ubucucike bw'ifuro n'imbaraga za mekanike; rikora nk'ingufu zo kwihutisha irangi rya PU, kole, n'ibifunga, rigabanya imikorere y'ingufu mu gihe rikongera uburambe bw'imigozi no kudakoresha imiti; byongeye kandi, DMDEE ni igikoresho cy'ingenzi mu gutunganya ifuro rya PU mu nganda zikora imyenda n'inkweto.

Urutonde rwacu rw'ibicuruzwa bya DMDEE rurimo amanota yihariye (ay'inganda, ay'ubuziranenge bwo hejuru, n'ay'impumuro nke) kugira ngo bihuze n'ibisabwa bitandukanye mu ikoreshwa, hamwe n'amabwiriza akomeye yo kugenzura ubuziranenge yemeza urwego rw'umwanda ruri munsi ya 0.05% n'ibipimo bihoraho bya fiziki-chemical kugira ngo habeho umusaruro uhamye. Dutanga ibisubizo byoroshye byo gutanga, kuva ku mapaki mato y'ibipimo kugeza ku gukwirakwiza ibikoresho byinshi bya IBC n'amakontena, hamwe n'inyandiko zuzuye zubahiriza amategeko (harimo MSDS zivugwa mu ndimi nyinshi, ibyemezo by'ubwikorezi bya UN, n'amadosiye yo kwiyandikisha ya REACH). Itsinda ryacu ryihariye rya tekiniki ritanga ubufasha ku giti cyaryo—nk'uburyo bwo kunoza imiterere ya PU, gupima ikoreshwa rya catalyst, n'ubuyobozi mu kubika neza—kugira ngo bigufashe kunoza inzira zo gukora no kuzamura ubushobozi bwo guhangana n'ibicuruzwa.
