Cov Ntawv Thov

3,3 {{{{}} (4 {{{}},}}}}) bis (1,1-hais txog cov ntaub ntawv kev tshawb fawb, tshwj xeeb hauv synthesis ntawm kev ua haujlwm siab polymers thiab resins. Cov compound no yog siv los ua qhov tseem ceeb hauv kev tsim cov thermosetting plooj cua, uas paub txog lawv cov kev ua haujlwm tsis txaus ntseeg. Nws tseem muaj kev sib xyaw ua ke hauv kev tsim cov neeg muaj zog thiab cov neeg sawv cev ntawm cov khoom sib txuas, txhim kho cov khoom siv kho tshuab thiab cua yam khoom ntawm cov khoom kawg. Tsis tas li ntawd, qhov no (urea) compound yog ua haujlwm hauv cov khoom siv nplaim taws, uas nws ua los txhim kho qhov hluav taws kub tsis kam ua kom muaj hluav taws kub thiab pleev xim. Hauv kev lag luam kws tshuaj thiab tshuaj lom neeg siv los ua cov reagent rau kev sib txuas lus tshwj xeeb, xws li cov qauv kev txhim kho ntau yam lossis cov kev cai tshwj xeeb. Zuag qhia tag nrho, nws lub luag haujlwm hauv polymer chemistry thiab cov ntaub ntawv txuj ci ua rau nws muaj txiaj ntsig zoo hauv kev txhim kho cov ntaub ntawv siab.

Cov txiaj ntsig

Cov txiaj ntsig tseem ceeb ntawm 3,3 {- (1 {}}}}}}}}}}}}}}}}}}}}}}}} { Hauv cov ntawv thov polymer, cov Urea muaj kev sib txuas ua ke txuas ntxiv mus txuas ntxiv-thermal ruaj khov ntawm cov ntaub ntawv kawg, ua rau lawv tiv thaiv ntau dua, hnav, thiab kev ntxhov siab thiab txhua yam kev ntxhov siab. Cov cuab yeej no yog tau txais txiaj ntsig tshwj xeeb nyob rau hauv kev tsim cov kev ua haujlwm siab thermosetting resins thiab nplaim-retardant cov ntaub ntawv, uas tsis ruaj khov yog qhov tseem ceeb. Nyob rau epoxy formulations, qhov no sib xyaw ua ke txhim kho cov txheej txheem kev kho kom zoo, ua rau cov khoom nrog lub zog zoo dua thiab lub siab ntev. Nws lub luag haujlwm hauv kev tsim cov ntaub ntawv siab dua tshiab rau cov ntaub ntawv kev lag luam nrog cov ntaub ntawv muaj kev txom nyem lossis cov kev mob siab, iberospace, thiab electronics. Tsis tas li ntawd, cov versatility ntawm 3,3- (4-pthyl-1,3-phenylene) bis (1,1-didethaty) hauv kev txhim kho tsev ntawm bioactive tshuaj thiab niche intermediaes.
