Thina Shanghai Theorem Chemicals sizibophelele kwizixhobo ezintsha zeekhemikhali, izinto ezikrwada zePolyurethane kunye nee-isocyanates ezikhethekileyo, Kwiminyaka edlulileyo, kwifilosofi ethi "Umgangatho ojolise kuwo, ubuchwephesha obukhokelwayo", inkampani iye yaphuhliswa njengeIsocyanate RE,I-RFE,1,5-Naphthalene Diisocyanate(NDI), I-PPDI (1,4-Phenylene Diisocvanate), njl. njl.…
Singabathengisi abaphambili be-NDI (1,5-naphthalene diisocyanate) eTshayina, ngobunyulu obuphezulu obuyi-99% min kunye nexabiso elikhuphisanayo, i-NDI yethu luhlobo lwe-polyurethane (PU) eyenziwe yi-diisocyanate. Xa ithelekiswa ne-MDI kunye ne-TDI, i-NDI ine-melting point ephezulu, i-molecular rigidity ephezulu, i-regularity, kunye ne-symmetry, enokuphucula ngokusisiseko inqanaba lokwahlulwa kwe-polyurethane kwinqanaba, okwenza i-polyurethane esekelwe kwi-NDI ifumane iipropati ezibalaseleyo zoomatshini nezomzimba. I-polyurethane esekelwe kwi-NDI inokumelana nokuguguleka okuphezulu, ukumelana nobushushu obuphezulu, 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.
