Ma Bonding agent atsopano omwe akukula monga HTPB, EHTTPB, ATBN, HTBN, CTBN...

Kwa ATBN, ATBN ndi rabara yamadzimadzi ya nitrile yokhala ndi magulu a amino omwe amagwira ntchito kumapeto onse a unyolo wa mamolekyu, omwe amatha kuchiritsidwa ndi zotsukira za isocyanate kapena kuchitapo kanthu ndi magulu a epoxy kuti azitha kuchiritsa. ATBN ili ndi kukana mafuta bwino, kukana kutentha, kukana kutopa komanso kumamatira mwamphamvu. Imatha kuchepetsa kutentha kwa gel ndi kutentha kwa epoxy resin ikagwira epoxy resin mwamphamvu.

ATBN imagwiritsidwa ntchito makamaka ngati chogwirizira cholimba cha epoxy resin, imatha kulimbitsa kulimba kwa zinthu zophatikizika, kulimbitsa mphamvu yodula ndi kupukuta, komanso ingagwiritsidwenso ntchito ngati guluu ndi chosindikizira chosiyana.

Magulu osiyanasiyana a ATBN motere:

Kwa HTBN, HTBN ndi rabara ya nitrile yamadzimadzi yokhala ndi magulu ogwira ntchito a hydroxyl kumapeto onse a unyolo wa mamolekyulu, yomwe ili ndi mphamvu zofanana ndi za fizikiki ndi mankhwala monga rabara ya nitrile ndipo imatha kuchiritsidwa ndi zinthu zochiritsa za isocyanate, Ili ndi reactivity yabwino komanso magwiridwe antchito abwino. HTBN ili ndi kukana mafuta bwino, kukana kutentha, kukana kutopa, komanso mphamvu yamphamvu yomatira.

HTBN imagwiritsidwa ntchito makamaka ngati chothandizira cholimba cha zomatira, zokutira, ndi ma resini, ndipo imatha kulimbitsa kulimba, kumatira, kulimba, mafuta ndi kukana kutentha kwa zinthu zopangidwa ndi zinthu zophatikizika.

Mtundu wosiyana wa HTBN ndi uwu:

Kwa CTBNButadiene acrylonitrile yamadzimadzi yotchedwa carboxyl-terminated butadiene acrylonitrile ndi mtundu umodzi wa rabara yamadzimadzi yomwe ili ndi gulu la carboxyl monga gulu lake la ntchito, ndipo code yake ndi CTBN, ingagwiritsidwe ntchito kwambiri m'mafakitale a ndege ndi m'mafakitale wamba. Nthawi zambiri CTBN imagwiritsidwa ntchito pamodzi ndi somatotype resin. CTBN yomwe ili ndi gulu logwira ntchito la carboxyl-terminated imatha kuchitapo kanthu pa epoxy resin kuti iwonjezere kulimba.

Ikhoza kusintha Hypro 1300x13 CTBN ndi Hunstman.

ndi magwiridwe antchito monga:

1. Zimawonjezera kulimba ndi kusinthasintha kwa ma resini a thermoset

2. Zimathandiza kuti zinthu zikhale zolimba kwambiri

3. Imawonjezera kukana ming'alu ndi kukana kugwedezeka

4. Zimathandiza kuti thupi likhale lolimba (kukana kutopa)

5. Kumawonjezera mphamvu za makina zomwe sizitentha kwambiri

6. Mtundu wa FDA ulipo
