Bis(2,6-disopropylphenyl) carbodiimideCAS 2162-74-5ke monomeric carbodiimide, moemeli oa mefuta e fapaneng ea anti-hydrolysis e nang le litšobotsi tsa bohloeki bo phahameng, 'mala o khanyang, ha ho na monko le ts'ebetso e phahameng. Bis(2,6-disopropylphenyl) carbodiimide e sebelisoa haholo linthong tse kang polyester polyol, nylon, lipolasetiki tsa boenjiniere tse nang le sehlopha sa ester, polyurethane elastomers, likhomaretsi, lisebelisoa tsa ho roala le oli e tlotsang. Bis (2,6-disopropylphenyl) carbodiimide e ka thibela ka katleho hydrolysis ea lisebelisoa tse joalo le ho tsitsisa thepa ea pele ea mochine. Ka nako e tšoanang,bis(2,6-disopropylphenyl) carbodiimide e ka boela ea thibela ho felisoa ha carboxyl e sebetsang ea thepa ea polyester. Lokisa lisebelisoa tse senyehileng tsa polyester le polyurethane,bis(2,6-disopropylphenyl) carbodiimide e ka lelefatsa bophelo ba ts'ebeletso ea lihlahisoa tsa polymer tlasa maemo a thata a ts'ebetso joalo ka mocheso o phahameng le mongobo..

Lefapheng la mahlale a thepa, bis(2,6-disopropylphenyl)carbodiimide, joalo ka monomeric carbodiimide anti-hydrolysis stabilizer, e fetohile sepheo sa indasteri bakeng sa ts'ebetso ea eona e ntle haholo le tebello e pharaletseng ea ts'ebeliso.

Ea pele,bis(2,6-disopropylphenyl) carbodiimide e sebelisoa haholo ho polyurethane elastomers (joalo ka TPU, CPU), li-adhesives, sole solutions le Microporous elastomers, joalo-joalo. Makaleng ana, ka ho eketsa 0.3-2.0% bis(2,6-disopropylphenyl)carbodiimide, bophelo ba ts'ebeletso ea sehlahisoa bo ka ntlafatsoa haholo, bo e atolosoa ka makhetlo a 1 ho isa ho a 3.

Ea bobeli, nakong ea phetoho ea lisebelisoa tsa polyester tse kang PET / PBT, ho eketsa bis (2,6-disopropylphenyl) carbodiimide ho ka fokotsa boleng ba acid ea polyester. Lintlafatso tse kholo tsa boleng ba lintho tse bonahalang li ka finyelloa ka chelete e fokolang ea ho eketsa, ho atolosa botsitso ba nako e telele ba thepa.

Ntle le ho sebelisoa e le moemeli oa anti-hydrolysis, bis (2,6-disopropylphenyl) carbodiimide e ka boela ea sebelisoa e le thuso ea ho sebetsana le li-carboxylic acid tse hlahisoang nakong ea extrusion. karabelo, ho thibela ho fokotseha ha boima ba limolek'hule, ho fokolisa tšenyo ea polymer nakong ea ts'ebetso, ho etsa hore ho be bonolo ho sebetsa le ho ntlafatsa ts'ireletso ea ts'ebetso ho bapisoa le mekhoa e meng.

Ho feta moo, bakeng sa PLA ea polasetiki e ka senyehang tikolohong, khanyetso e mpe ea hydrolysis esale e le tšitiso e kholo e thibelang ts'ebeliso ea eona e pharaletseng. PLA e senyeha habonolo libakeng tse mongobo, e amang ts'ebetso ea eona le nako ea bophelo. Leha ho le joalo, ka ho eketsa 0.3-0.5% bis(2,6-disopropylphenyl)carbodiimide ho PLA, ho hanyetsa metsi ho ka ntlafatsoa haholo ka makhetlo a 3-7, ka katleho ho atolosato sebelisa masimo a kopo ea PLA.

Ka kakaretsomary, bis(2,6-disopropylphenyl)carbodiimide, joalo ka sethibela-ts'ebetso se phahameng sa anti-hydrolysis stabilizer, se bontšitse bokhoni bo pharaletseng ba ts'ebeliso le bokhoni lefapheng la mahlale a thepa. boleng.Its thepa e babatsehang ea 'mele le lik'hemik'hale, mefuta e mengata ea likopo, le tharollo e lebisitsoeng bakeng sa lisebelisoa tse khethehileng (tse kang PLA) li etsa hore bis(2,6-disopropylphenyl)carbodiimide e be moetapele oa ho tsitsisa thepa. Ka tsoelopele e tsoelang pele ea mahlale a thepa le tlhokomeliso e ntseng e eketseha ea ts'ireletso ea tikoloho, bis(2,6-disopropylphenyl)carbodiimide le lihlahisoa tsa eona tse tšoanang li lebelletsoe ho khothaletsoa le ho sebelisoa mafapheng a mangata.
