I-1,5-naphthalene diisocyanate (NDI) luhlobo lwe-polyurethane (PU) eyenziwe yi-diisocyanate. Xa ithelekiswa ne-MDI kunye ne-TDI, i-NDI ene-melting point ephezulu, i-molecular rigidity ephezulu, i-regularity, kunye ne-symmetry, enokuphucula ngokusisiseko inqanaba lokwahlulwa kwe-polyurethane ngesigaba, okwenza i-polyurethane esekelwe kwi-NDI ifumane iipropati ezibalaseleyo zoomatshini nezomzimba. I-polyurethane esekelwe kwi-NDI inokumelana nokuguguleka okuphezulu, ukumelana nobushushu okuphezulu, ukumelana nokugqwala kunye neepropati ezibalaseleyo zokuguquguquka, kwaye isetyenziswa kakhulu kwiimeko zomthwalo ophezulu kunye nokumelana nobushushu.
I-NDI (1,5-Naphthalene Diisocyanate) yinto eluhlaza eyenziwe nge-polyurethane ephucukileyo, enokusetyenziswa ukwenza i-polyurethane elastomer enobulukhuni obuphezulu kunye nobunzima obuphezulu. I-NDI polyurethane elastomer isebenza kakuhle kakhulu. Isebenza ngendlela engenakuthelekiswa nanto nayo nayiphi na enye i-polyurethane elastomer, njengokusebenza okunamandla okugqwesileyo, ukusebenza okuphezulu kakhulu koomatshini, ukumelana nokusika okuhle kakhulu, ukumelana nokuguguleka kunye nokumelana nobushushu. Ke ngoko, ii-NDI polyurethane elastomers zisetyenziswa kakhulu kwii-automobile shock absorbers, amavili e-forklift bearing, ukuprinta kunye nokudaya ii-rollers zerabha zelaphu, ii-raber scrapers, ii-bridge construction buffer blocks, imboni yezomkhosi, njl.njl.
I-elastomer ephoswayo eyenziwe yi-NDI ineempawu ezibalaseleyo zokuguquguquka kunye nokumelana nokuguguleka, kwaye inomswakama omncinci, ukumelana okuphezulu, kunye nobushushu obuncinci bangaphakathi. Ingasetyenziswa kwiimeko zomthwalo ophezulu oguquguqukayo kunye nokumelana nobushushu. Iimveliso ezibunjiweyo ezenziwe nge-NDI zinamandla aphezulu okukrazula, ukukrazula okuphantsi, iseti ephantsi yoxinzelelo kunye nokumelana okuhle. Iimveliso ze-elastomer ze-polyurethane ezine-microporous polyurethane ezisekwe kwi-NDI zinobushushu obuphantsi bomzimba, ukuguqulwa okuncinci okusisigxina kunye nokuqina okuhle phantsi komthwalo oguquguqukayo. Le nto ikhethekileyo ye-polyurethane ene-microporous isetyenziselwa ikakhulu ukufunxa ukushaqeka kweemoto kunye nezinto ezikhuselayo.
Singabantu abaphambili kwimarike ye-NDI. Umthamo wethu wemveliso ye-NDI yi-500 MT ngonyaka kwaye uyaqhubeka nokukhula.
