I-1,5-naphthalene diisocyanate (NDI) luhlobo lwe-polyurethane (PU) eyenziwa yi-disocyanate. Xa kuthelekiswa ne-MDI kunye ne-TDI, i-NDI enendawo ephezulu yokunyibilika, ukuqina kwemolekyuli ephezulu, ukuqheleka, kunye ne-symmetry, enokuphucula ngokusisiseko inqanaba lokwahlulwa kwesigaba se-polyurethane, ukwenza i-NDI-based polyurethane ifumane iipropathi ezigqwesileyo zoomatshini nezomzimba. I-NDI-based polyurethane inokumelana nokunxiba okuphezulu, ukumelana nobushushu obuphezulu, ukuchasana nokugqwala kunye neempawu ezibalaseleyo eziguquguqukayo, kwaye isetyenziswa ikakhulu kumthwalo onamandla kunye nezihlandlo zokumelana nobushushu.
I-NDI (1,5-Naphthalene Diisocyanate) yinto eluhlaza ye-polyurethane ephezulu, engasetyenziselwa ukuvelisa i-polyurethane elastomer ene-elasticity ephezulu kunye nobunzima obuphezulu. I-NDI polyurethane elastomer inomsebenzi ogqwesileyo. Inomsebenzi ongenakuthelekiswa nayo nayiphi na enye i-polyurethane elastomer, efana nokusebenza okugqwesileyo okuguquguqukayo, ukusebenza okuphezulu kakhulu koomatshini, ukuxhathisa okugqwesileyo kokusika, ukumelana nokunxiba kunye nokumelana nobushushu. Ke ngoko, ii-elastomers ze-NDI polyurethane zisetyenziswa kakhulu kwi-absorber yokothuka kwemoto, i-forklift ethwele amavili, ukuprinta kunye nokudaya iirola zerabha ezilukiweyo, izikrweqe zerabha, iibhloko zebhulorho zokwakhiwa kwebhulorho, ishishini lomkhosi, njl.
I-elastomer ekhatywayo eyenziwe yi-NDI ineempawu ezibalaseleyo eziguquguqukayo kunye nokumelana nokunxiba, kunye nokuthomalalisa okuncinci, ukomelela okuphezulu, kunye nobushushu obuncinci bangaphakathi. Ingasetyenziswa kumthwalo oguqukayo ophezulu kunye nezihlandlo zokumelana nobushushu. Iimveliso ezibunjiweyo ezenziwe nge-NDI zinamandla aphezulu okukrazula, i-abrasion ephantsi, isethi yoxinzelelo oluphantsi kunye nokuqina okuhle kakhulu. Imveliso ye-NDI-based microporous polyurethane elastomer inobushushu obuphantsi obuphantsi, i-deformation encinci esisigxina kunye nokuqina okulungileyo phantsi komthwalo oguqukayo. Esi sixhobo sikhethekileyo se-polyurethane se-microporous sisetyenziswa ikakhulu ukufunxa ukothuka kwemoto kunye nezinto zokuthoba.
Singumdlali ophambili kwimarike ye-NDI. Umthamo wethu wokuvelisa we-NDI yi-500 MT ngonyaka kwaye ugcine ukwandisa.
Ukupakisha: 20kgs / idrum yentsimbi; 40kgs/igubu lentsimbi; 600kgs/ibhegi
Ukugcinwa kunye nokuthutha: gcina kwindawo yokugcina impahla epholileyo neyomileyo. Ukukhusela kumlilo kunye nemithombo yobushushu
