Desmodur RE / Isocyanate RE zomatira CAS 2422-91-5
RE yathu ndi yogwira ntchito kwambiri yolumikizira mtanda, Yogwiritsidwa ntchito mu zomatira zopangidwa ndi hydroxyl polyurethane, mphira wachilengedwe kapena wopangidwa, ili ndi mphamvu zomangira zabwino kwambiri mu rabara ndi kabati yogwiritsidwa ntchito mu utomoni, antioxidant, plasticizing agent, pressure-sensitive etc. itha kugwiritsidwa ntchito ngati crosslinker m'malo mwa BAYER's Desmodur RE.
Zambiri zamalonda:
Dzina la mankhwala: Triphenylmethane-4,4',4''-triisocyanate
Molecular formula: C22H13N3O3
CAS: 2422-91-5
MW: 367.36
Khalidwe: wopanga
Kapangidwe kake: HC[NCO]3

RE yathu, yomwe imatchedwanso TTI, ndi yankho lomwe lili ndi 27.5% triphenylmethane-4,4ˊ,4〞-triisocyanate ndi 72.5% ethyl acetate.Ndi njira yochiritsira padziko lonse lapansi / cholumikizira chomatira chotengera hydroxyl polyurethane, mphira wachilengedwe komanso wopangira, makamaka wolumikiza zida zalabala.Amagwiritsidwanso ntchito kwambiri polumikiza zitsulo ndi rabara.Komanso, RE ingagwiritsidwe ntchito pa utomoni, antioxidant, plasticizer, ndi zina zotero. Pamalo omatira, RE imagwiritsidwa ntchito ngati njira yolumikizira pa neoprene adhesive ndi / kapena p hydroxyl polyurethane adhesive m'madera a nsapato.Nthawi zambiri, pochiritsa zomatira za magawo 100 polemera (pbw) kutengera kuchuluka kwa 4-7 pbw RE.Moyo wa mphika wa zomatira zosakanikirana ndi pafupifupi maola.
Zomatira zamagulu awiri ziyenera kugwiritsidwa ntchito mkati mwa nthawi yomwe ingagwiritsidwe ntchito mutayika RE.Kutalika kwa nthawi yogwira ntchito sikungokhudzana ndi zomatira za polima, komanso zigawo zina zofunikira (monga utomoni, antioxygen, plasticizer, zosungunulira, etc. Pamene pafupi ndi nthawi yoyenera, nthawi zambiri maola angapo kapena tsiku limodzi logwira ntchito, zomatira Kumakhala kovuta kugwira ntchito, ndipo kukhuthala kumakwera posachedwa.Pomaliza, Amakhala odzola osasinthika.Zomatira zamtundu 100, Hydroxyl polyurethane (Polyurethane account pafupifupi 20%), RE mlingo 4-7.Chloroprene rabara (Rubber account for around 20%) , RE yathu imachita 4-7.
Kulongedza:
750g/botolo, mabotolo 20 m'katoni imodzi, makatoni 24 kapena 30 mu mphasa imodzi;
20kg/ng'oma, ng'oma 18 kapena ng'oma 27 mu mphasa imodzi;
55kg / ng'oma, 8 kapena 12 ng'oma mu mphasa limodzi;
180kg/ng'oma, ng'oma 4 mu mphasa imodzi
Kusungirako:
Chonde kusungidwa mumtsuko wosindikizidwa woyambirira pansi pa 23 ℃, zinthuzo zitha kusungidwa mokhazikika kwa miyezi 12.Imakhudzidwa kwambiri ndi ambiri;adzakhala kupanga mpweya woipa ndi insoluble urea mu anachita ndi madzi.Ngati kukhudzana ndi mpweya wa teh kapena kuwala, zidzafulumizitsa kusintha kwa mtundu, koma ntchito yothandiza sidzakhudzidwa.
