ʻO Desmodur RE, ka mea i kapa ʻia ʻo CAS 2422-91-5, he mea maʻalahi a hoʻohana nui ʻia. Ma muli o kāna hana maikaʻi loa a me nā pono, ua hoʻohana nui ʻia i nā ʻoihana like ʻole. Ma kēia ʻatikala, ʻimi mākou i ka hoʻohana ʻana o Desmodur a ʻike i ke kumu i kaulana loa ai i nā mea hana.
ʻO Desmodur RE no ka ʻohana o nā diisocyanates aromatic, nā pūhui i hoʻohana nui ʻia i ka hana ʻana o nā polyurethane coatings, adhesives a me nā elastomers. He wai melemele māmā ia i ka wai amber i hui pū ʻia nā isomers me nā ʻano kemika like. ʻO ka mea nui o Desmodur RE he toluene diisocyanate (TDI), i hoʻohana nuiʻia i ka hanaʻana i ka polyurethane foam.
ʻO kekahi o nā hoʻohana nui oDesmodur REaia i ka hana ʻana i nā uhi polyurethane. Hāʻawi nā uhi polyurethane i ka pale maikaʻi loa mai ka ʻino, ka wā a me ka abrasion. Ua ʻike ʻia lākou no ko lākou kūpaʻa kiʻekiʻe a me ka hana maikaʻi loa i nā wahi paʻakikī. ʻO Desmodur RE kahi mea koʻikoʻi i loko o kēia mau hoʻopihapiha hoʻopihapiha, hāʻawi iā lākou i hoʻonui i ka paʻakikī, adhesion a me ke kūpaʻa kemika.
ʻO kekahi noi koʻikoʻi o Desmodur RE ka hana ʻana i nā mea hoʻopili polyurethane. Hoʻohana nui ʻia nā polyurethane adhesives i ka ʻoihana kaʻa, kūkulu hale a me nā ʻoihana hale ma muli o ko lākou ikaika paʻa kiʻekiʻe a me ka versatility. Hoʻonui ʻo Desmodur RE i ka ikaika paʻa o nā polyurethane adhesives, e ʻae iā lākou e hoʻopili i nā substrate like ʻole e like me ke metala, plastic a me ka lāʻau. ʻO kēia ka mea kūpono iā lākou no ka lamination, hoʻopaʻa a hoʻopaʻa ʻana i nā noi.
Hoʻohana pū ʻia ʻo Desmodur RE i ka hana ʻana i nā elastomers polyurethane. Hōʻike nā elastomers polyurethane i nā waiwai mechanical maikaʻi loa e like me ka elasticity kiʻekiʻe, ka pale ʻana i ka waimaka a me ke kūpaʻa abrasion. Hoʻohana ʻia lākou i nā ʻoihana e like me nā kāmaʻa, kaʻa a me ka hana ʻoihana. He hana koʻikoʻi ʻo Desmodur RE i ka synthesis o kēia mau elastomers, e hāʻawi ana iā lākou i ka ikaika tensile maikaʻi a me nā waiwai elongation.
Eia kekahi,Desmodur REʻike ʻia no kona hoʻōla wikiwiki ʻana. ʻO ia ke ʻano hiki ke hoʻololi koke me nā polyols e hana i kahi pūnaewele polyurethane ikaika. Makemake nui ʻia ka hoʻōla wikiwiki ʻana i nā ʻoihana e koi ana i nā manawa huli wikiwiki, e like me nā ʻoihana kaʻa a i ʻole nā ʻoihana kūkulu. Eia kekahi, he kūpono maikaʻi ʻo Desmodur RE me ka nui o nā polyols, e hiki ai i nā mea hana ke hoʻololi i nā waiwai o kā lākou huahana i nā koi kikoʻī.
I ka hopena, Desmodur RE (CAS 2422-91-5) he mea hoʻohana nuiʻia me nā noi ākea i nāʻoihana e like me ka uhiʻana, nā mea hoʻopili a me nā elastomers. ʻO kāna mau waiwai kūikawā, me ka hoʻonui ʻia ʻana o ka paʻakikī, adhesion a me ka hoʻōla wikiwiki ʻana, lilo ia i koho kaulana i waena o nā mea hana. ʻO ka hāʻawi ʻana i ka pale corrosion ma o ka polyurethane coatings, ka loaʻa ʻana o nā mea paʻa ikaika i nā adhesives, a i ʻole ka hoʻonui ʻana i nā waiwai mechanical o elastomers, ua hōʻoia ʻo Desmodur RE he mea nui i ka hana ʻana i nā mea hana kiʻekiʻe.
