Dab tsi yogPolyester thiab TDI Polyurethane Prepolymer?
Polyester thiab TDI (Toluene Diisocyanate) polyurethane prepolymer yog cov khoom siv ntau yam siv hauv ntau qhov kev lag luam rau nws cov khoom siv zoo heev thiab ua haujlwm ntev.
Polyester thiab TDI polyurethane prepolymer feem ntau yog tsim los ntawm:
Polyester Polyol: Polyester polyol yog ib qho tseem ceeb ntawm cov tshuaj tiv thaiv condensation ntawm diol (xws li ethylene glycol lossis propylene glycol) nrog dicarboxylic acid (xws li adipic acid lossis phthalic acid). Polyester polyols muab kev yooj yim thiab ua haujlwm zoo rau cov khoom siv polyurethane kawg.
Toluene Diisocyanate (TDI): TDI yog ib qho aromatic diisocyanate siv los ua cov isocyanate tivthaiv hauv prepolymer synthesis. Nws reacts nrog polyester polyol los tsim urethane linkages, uas yog lub luag hauj lwm rau cov khoom lub zog thiab durability.
Dab tsi yog cov ntawv thov rau polyester TDI?
Coatings thiab Adhesives:
Siv nyob rau hauv industrial coatings rau nws abrasion kuj thiab chemical durability.
Formulated rau hauv cov nplaum rau kev sib txuas ntau yam substrates, nrog rau cov hlau, yas, thiab ntoo.
Sealants thiab Caulks:
Siv nyob rau hauv kev tsim kho sealants thiab caulks vim nws yooj thiab huab cua tsis kam.
Muab cov adhesion zoo rau pob zeb, iav, thiab lwm yam khoom siv hauv tsev.
Elastomers thiab Foams:
Siv nyob rau hauv zus tau tej cov saj zawg zog thiab nruj polyurethane foams.
Cov ntaub ntawv ruaj khov elastomers siv hauv cov khoom siv tsheb, khau, thiab cov khoom siv kho mob.
Moulding:
Castable rau hauv moulds los tsim cov ncauj lus kom ntxaws thiab complex duab rau prototyping thiab ntau lawm.
Siv nyob rau hauv rotational molding, txhaj tshuaj molding, thiab lwm yam txheej txheem casting.
Textiles thiab Fibers:
Impregnated rau hauv textiles los txhim kho dej repellency thiab durability.
Coated rau fibers rau kev siv hauv upholstery, ntaub pua plag, thiab khaub ncaws tiv thaiv.
