Bis(2,6-diisopropylphenyl) carbodiimideCAS 2162-74-5ke monomeric carbodiimide, mofuta o emelang wa moemeli wa anti-hydrolysis o nang le dibopeho tsa bohloeki bo phahameng, mmala o bobebe, o se nang monko le mosebetsi o phahameng. Bis(2,6-diisopropylphenyl) carbodiimide e sebediswa haholo dinthong tse kang polyester polyol, nylon, dipolasetiki tsa boenjiniere tse nang le sehlopha sa ester, polyurethane elastomers, dikhomaretsi, ditsamaiso tsa ho kwahela le oli e tlotsang. Bis(2,6-diisopropylphenyl) carbodiimide e ka thibela ka katleho hydrolysis ya dintho tse jwalo le ho tsitsisa thepa ya pele ya mechine. Ka nako e ts'oanang,bis(2,6-diisopropylphenyl) carbodiimide e ka boela ea thibela ho fela ha carboxyl e sebetsang ea thepa ea polyester. Lokisa polyester e senyehileng le thepa ea polyurethane,bcarbodiimide ea is(2,6-diisopropylphenyl) e ka lelefatsa bophelo ba ts'ebeletso ea lihlahisoa tsa polymer tlas'a maemo a thata a ts'ebetso joalo ka mocheso o phahameng le mongobo..

Lefapheng la saense ea thepa, bis(2,6-diisopropylphenyl)carbodiimide, e le sesebelisoa sa ho thibela hydrolysis sa monomeric carbodiimide, e se e le setsi sa indasteri ka lebaka la ts'ebetso ea eona e ntle le menyetla e mengata ea ts'ebeliso.

Taba ea pele,bis(2,6-diisopropylphenyl) carbodiimide e sebediswa haholo ho polyurethane elastomers (jwalo ka TPU, CPU), dikhomaretsi, ditharollo tsa sole le di-Microporous elastomers, jj. Masimong ana, ka ho eketsa 0.3-2.0% bis(2,6-diisopropylphenyl)carbodiimide., Bophelo ba tšebeletso ea sehlahisoa bo ka ntlafala haholo, ba bo eketsa ka makhetlo a 1 ho isa ho a 3.

Taba ea bobeli, nakong ea ts'ebetso ea phetoho ea thepa ea polyester joalo ka PET/PBT, ho eketsa bis(2,6-diisopropylphenyl) carbodiimide ho ka fokotsa boleng ba asiti ea polyester. Lintlafatso tse kholo boleng ba thepa li ka finyelloa ka bongata bo tlase ba ho eketsa, ho atolosa botsitso ba nako e telele ba thepa.

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

Ho phaella moo, bakeng sa PLA ea polasetiki e bolang tikolohong, khanyetso e fokolang ea hydrolysis esale e le bothata bo boholo bo sitisang ts'ebeliso ea eona e pharaletseng. PLA e senyeha habonolo libakeng tse mongobo, e amang ts'ebetso ea eona le nako ea eona ea bophelo. Leha ho le joalo, ka ho eketsa 0.3-0.5% bis(2,6-diisopropylphenyl)carbodiimide ho PLA, khanyetso ea eona ea metsi e ka ntlafatsoa haholo ka makhetlo a 3-7, e leng se etsang hore ho be le keketseho e kholo eatmasimo a kopo a PLA.

Ka kakaretsomary, bis(2,6-diisopropylphenyl)carbodiimide, e le sesebelisoa se matla sa ho thibela hydrolysis, se bontšitse bokhoni bo pharaletseng ba ts'ebeliso le bokhoni lefapheng la mahlale a thepa.ItThepa ea eona e ntle ea 'mele le ea lik'hemik'hale, mefuta e mengata ea lits'ebetso, le litharollo tse reretsoeng thepa e itseng (joalo ka PLA) li etsa hore bis(2,6-diisopropylphenyl)carbodiimide e be moetapele ho tiiseng thepa. Ka tsoelo-pele e tsoelang pele ea saense ea thepa le temoho e ntseng e eketseha ea ts'ireletso ea tikoloho, bis(2,6-diisopropylphenyl)carbodiimide le lihlahisoa tsa eona tse tšoanang li lebelletsoe ho khothaletsoa le ho sebelisoa masimong a mangata.
