Application:

Toluene diisocyanates inoshandiswa kunyanya kugadzira furo re polyurethane rinochinjika kuti rishandiswe mufenicha, zvekurara, uye zvigaro zvemotokari nendege.Zvimwewo, mashandisirwo madiki ndee polyurethane elastomers (yemota mabumper mavhavha, maindasitiri anomonereka, emitambo soles uye bhutsu, uye nhumbi dzemuchina) uye machira (yekunatsa mota, kupera kwemapuranga, uye yakakwirira-inoshanda anti-corrosion coatings) (ICIS 2009).Toluene diisocyanate-based rigid polyurethane foam inoshandiswa mumafiriji emumba uye kune yekugara sheathing kana denga rekutengesa mubhodhi kana laminate fomu (IARC 1986).Furo rakasimba rekuti “dira-inplace” kana kuti “spray-in” rinoshandiswa sekudzivirira zvidhoma zvemarori, mota dzenjanji dzinotakura zvinhu, uye midziyo inotakura zvinhu.Polyurethane-modified alkyds ine angangoita 6% kusvika 7% isocyanate, kunyanya toluene diisocyanates, uye anoshandiswa sezvinhu zvekunamira, senge pasi kupera, huni kupera, uye pendi.Mishonga yekuchenesa unyoro inoshandiswa sehuni uye zvisimbiso zvekongiri uye kupera kwepasi.Ndege, marori, uye mabhanhire emotokari anowanzo umbwa ne toluene diisocyanate prepolymer systems.Castable urethane elastomers anoshandiswa mumashandisirwo anoda simba, kuchinjika, uye kubatwa nekuvhunduka, uye anoshingirira kumafuta, zvinonyungudutsa, uye ultraviolet mwaranzi.Iwo anoshandiswa mukunamira uye sealant makomisheni uye muzvikamu zvemotokari, bhutsu soles, rollerskate mavhiri, pond liners, uye mabhegi eropa.Anoshandiswawo minda inoil nemigodhi.Zvimwe zvigadzirwa zve elastomer zvinogadzirwa kubva kune yakachena 2,4 isomer pane iyo 80:20 musanganiswa.

Mapoka anoshanda muTDI anoita nemapoka ehydroxyl kuti aumbe urethane linkages, ayo anoshandiswa mukugadzira anochinjika polyurethane furo kuti ashandiswe mufenicha, yekurara, uye yemotokari uye yekushambadzira zvigaro zvekufambisa.Mamwe mashandisirwo anosanganisira polyurethane elastomers anoshandiswa mumavhavha emota mabumper, ma roller emaindasitiri, shangu dzemitambo, pamwe chete nezvinhu zvemuchina uye machira (simbi, huni, uye highperformance anticorrosion coatings).TDI-based rigid polyurethane foam inoshandiswa mumafiriji emumba uye pakuvaka kwekugara senge sheathing uye denga rekutengesa.TDI yakapfapfaidza-mune furo rakaomarara rinoshandiswa sekuvhara matiraki erori, mota dzenjanji dzinotakura zvinhu, uye midziyo yekutakura mhiri kwemakungwa.Kunyorova-kupora TDI machira anoshandiswa sehuni uye kongiri sealants uye pasi kupera.
