Zomatira RFE / DESMODUR RFE CAS 4151-51-3

Kufotokozera Kwachidule:

Zomatira ziwiri ziyenera kugwiritsidwa ntchito munthawiyo mutayika mu RFE. Kutalika kwa nthawi yogwiritsidwa ntchito sikukhudzana kokha ndi zomata za polima, komanso zinthu zina zofunikira (Monga reisn, antioxygen, plasticizer, zosungunulira, ndi zina zambiri mukakhala pafupi ndi nthawi, nthawi yayitali kapena tsiku limodzi logwira ntchito, zomatira kumakhala kovuta kugwira ntchito, ndipo mamasukidwe akayendedwe amakula posachedwa, Potsirizira pake, amakhala osungunuka osasintha. 100 zomatira zamtengo wapatali, Hydroxyl polyurethane (Polyurethane account for 20%), RFE mlingo 4-7. Chloroprene rubber (Rubber account for 20%) , Mlingo wathu wa RFE 4-7.

Mkulu womata womangiriza Isocyanate RFE amatha kusintha DESMODURE RFE

Zida Zamagulu

RFE polyisocyanate ndi cholumikizira chothandiza kwambiri cha zomata zochokera ku polyurethane, labala wachilengedwe ndi mphira wopangira, imathandizanso pakukongoletsa zomata za zida zopangira mphira. Itha kugwiritsidwa ntchito ngati crosslinker.

Zambiri Zamalonda

Katundu wazogulitsa: RFE, RF

Mankhwala chilinganizo: C21H12N3O6SP

Sub sub voliyumu: 465

Malo osungunuka: 84-86 ℃

Maonekedwe

Transpareant chikasu-bulauni madzi. Mtundu wake sumakhudza kulumikizana kwamphamvu.

Zida zimatha kukhala ndi matope a lamellar.

Kugwiritsa Ntchito Zamalonda

Zomatira ziwiri ziyenera kugwiritsidwa ntchito munthawiyo mutayika mu RFE. Kutalika kwa nthawi yogwiritsidwa ntchito sikukhudzana kokha ndi zomata za polima, komanso zinthu zina zofunikira (Monga reisn, antioxygen, plasticizer, zosungunulira, ndi zina zambiri mukakhala pafupi ndi nthawi, nthawi yayitali kapena tsiku limodzi logwira ntchito, zomatira kumakhala kovuta kugwira ntchito, ndipo mamasukidwe akayendedwe amakula posachedwa, Potsirizira pake, amakhala osungunuka osasintha. 100 zomatira zamtengo wapatali, Hydroxyl polyurethane (Polyurethane account for 20%), RFE mlingo 4-7. Chloroprene rubber (Rubber account for 20%) , Mlingo wathu wa RFE 4-7.

Zolemba Zina Zofananira

Kulongedza:

750g / botolo, mabotolo 20 mu katoni imodzi, makatoni 24 kapena 30 mu mphasa umodzi;

20kg / ng'oma, ngoma 18 kapena ng'oma 27 mu mphasa imodzi;

55kg / ng'oma, 8 kapena 12 ng'oma mu mphasa umodzi;

180kg / ng'oma, ng'oma 4 mu mphasa imodzi

Yosungirako:

Chonde kusungidwa mumtsuko woyambirira wosindikizidwa pansi pa 23 ℃, mankhwalawa akhoza kusungidwa okhazikika kwa njenjete zisanu ndi chimodzi.

Zogulitsa zathu zonse ndizofunika kwambiri ku chinyezi; Ipanga carbon dioxide komanso insoluble urea poyankha ndi madzi. Ngati kuwonetsedwa mlengalenga kapena / ndikuwala, kudzafulumizitsa kusintha kwamitundu yazinthu.

Koma ntchitoyo idzakhudzidwa ndi bot.)

Chitetezo:

Chikhalidwe chowopsa, chotentha kwambiri, chimapangitsa kuti maso, ngati atapumira atha kuyambitsa chifuwa. Kukhudza pafupipafupi kumatha kuyambitsa khungu kapena kuuma. Nthunzi wa zinthu zitha kupangitsa munthu kutopa komanso chizungulire.
