Mtengo wabwino kwambiri wa Desmodur RE wa zomatira CAS 2422-91-5 Triphenylmethane -4,4`,4"-triisocyanate/ Methylidintri-p-phenylene triisocyanate
RE yathu ndi yolumikizirana kwambiri, Yogwiritsidwa ntchito mu zomatira zopangidwa ndi hydroxyl polyurethane, rabara yachilengedwe kapena yopangidwa, ili ndi mphamvu yabwino kwambiri yolumikizirana mu rabara ndipo imagwiritsidwa ntchito mu resin, antioxidant, plasticizing agent, ndi zina zotero. Ingagwiritsidwe ntchito ngati crosslinker m'malo mwa BAYER's Desmodur RE.
Tsatanetsatane wa malonda:
Dzina la Mankhwala: Triphenylmethane-4,4',4''-triisocyanate
Fomula ya Molekyulu: C22H13N3O3
CAS: 2422-91-5
MW: 367.36
Khalidwe: wopanga
Fomula ya kapangidwe kake: HC[NCO]3
Kuchuluka: 1.0g/c m3, 20℃
Malo osungunuka: 89℃
RE yathu, yomwe imatchedwanso TTI, ndi yankho lomwe lili ndi 27.5% triphenylmethane-4,4ˊ,4〞-triisocyanate ndi 72.5% ethyl acetate. Ndi mankhwala ochiritsira/crosslinker omwe amagwiritsidwa ntchito popanga zomatira pogwiritsa ntchito hydroxyl polyurethane, rabara zachilengedwe komanso zopangidwa, makamaka abwino kwambiri popanga zinthu zomatira. Imagwiritsidwanso ntchito kwambiri popanga zitsulo zomatira ndi rabara. Kuphatikiza apo, RE ingagwiritsidwe ntchito pa resin, antioxidant, plasticizer, ndi zina zotero. Mu gulu lomatira, RE imagwiritsidwa ntchito ngati chomatira chomatira pa gulu lomatira la neoprene ndi/kapena gulu lomatira la p hydroxyl polyurethane m'malo a nsapato. Kawirikawiri, pa gulu lomatira la magawo 100 polemera (pbw) kutengera kuchuluka komwe kumalimbikitsidwa kwa 4-7 pbw RE. Moyo wa gulu lomatira losakanikirana ndi pafupifupi maola.
Guluu wa zigawo ziwiri uyenera kugwiritsidwa ntchito mkati mwa nthawi yogwiritsidwa ntchito mutayika RE. Kutalika kwa nthawi yogwiritsidwa ntchito sikungokhudzana ndi kuchuluka kwa polima mu guluu, komanso zinthu zina zofunika (monga utomoni, antioxygen, plasticizer, solvent, ndi zina zotero. Ikakhala pafupi ndi nthawi yogwiritsidwa ntchito, nthawi zambiri maola ochepa kapena tsiku limodzi logwira ntchito, guluu umakhala wovuta kugwiritsa ntchito, ndipo kukhuthala kumawonjezeka posachedwa. Pomaliza, umakhala jelly wosasinthika. Guluu wamtundu wa 100, Hydroxyl polyurethane (Polyurethane imakhala pafupifupi 20%), RE mlingo 4-7. Chloroprene rabara (Rabala imakhala pafupifupi 20%), RE yathu imachita 4-7.
Kulongedza:
750g/botolo, mabotolo 20 mu katoni imodzi, makatoni 24 kapena 30 mu phaleti imodzi;
20kg/ng'oma, ng'oma 18 kapena ng'oma 27 mu mphasa imodzi;
55kg/ng'oma, ng'oma 8 kapena 12 mu mphasa imodzi;
180kg/ng'oma, ng'oma zinayi mu mphasa imodzi
Malo Osungirako:
Sungani mu botolo loyambirira lotsekedwa pansi pa 23℃, zinthuzo zitha kusungidwa bwino kwa miyezi 12. Zimakhudzidwa kwambiri ndi ulusi; zimapanga carbon dioxide ndi urea yosasungunuka mu yankho ndi madzi. Ngati zikhudzidwa ndi mpweya kapena kuwala, zidzasintha mtundu mwachangu, koma ntchito yake sidzakhudzidwa.
