Kuchotsa HTPB mu epoxidation: Magwiridwe antchito ndi kagwiritsidwe ntchito
Hydroxyl-terminated polybutadiene (HTPB) ndi polima yosinthasintha yodziwika bwino chifukwa cha mphamvu zake zabwino kwambiri zamakanika, kutentha kochepa kwa kusintha kwa galasi,
komanso kukana kwambiri mankhwala ndi nyengo. Chimodzi mwa njira zofunika kwambiri posinthira HTPB kuti iwonjezere mphamvu zake ndi epoxidation.
Kuphatikizika kwa HTPB kumaphatikizapo kuwonjezera magulu a epoxide ku msana wa polima, zomwe zimapangitsa kuti zinthu zosinthidwa zikhale ndi makhalidwe abwino ogwirira ntchito.
Nkhaniyi ikufotokoza za epoxidation ya HTPB, momwe imagwirira ntchito, komanso momwe imagwiritsidwira ntchito m'njira zosiyanasiyana.
The Kuchuluka kwa hydroxyl-terminated polybutadiene (HTPB) ndi gawo lofunika kwambiri pakupanga zinthu zapamwamba zokhala ndi mawonekedwe owonjezera.
Njirayi imaphatikizapo momwe HTPB imachitira ndi epoxidizing agent, monga peracetic acid kapena hydrogen peroxide, kuti ibweretse magulu a epoxide pamodzi.
unyolo wa polima. Kusintha kumeneku kumapangitsa kuti HTPB ikhale yolimba, yolimba, komanso yolimba, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito ndi zinthu zambiri.
mitundu yosiyanasiyana ya ntchito.
Chimodzi mwa zabwino zazikulu za magwiridwe antchito a HTPB yosungunuka ndi mphamvu zake zomamatira bwino. Kuyambitsa magulu a epoxide kumawonjezera kugwirizana
ya HTPB yokhala ndi zinthu zosiyanasiyana, zomwe zimapangitsa kuti pakhale kumamatira bwino pa ntchito zomatira ndi zotsekera. Kuphatikiza apo, HTPB yokhala ndi epoxidized imaonetsa kukana bwino kwambiri
ku zinthu zosungunulira, mafuta, ndi mafuta, zomwe zimapangitsa kuti ikhale chisankho chabwino kwambiri cha zokutira, zomatira, ndi zotsekera m'malo ovuta.
Komanso, Kuchuluka kwa epoxidation ya HTPB zimapangitsa kuti kutentha kukhale kolimba komanso kuti malawi azichedwa. Kupezeka kwa magulu a epoxide kumawonjezera ma polima
Kukana kutentha ndi malawi, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito mu ndege, magalimoto, ndi zomangamanga komwe chitetezo cha moto chili chofunikira kwambiri.
Kuphatikiza apo, HTPB yokhala ndi epoxidized ingagwiritsidwe ntchito ngati chomangira popanga zinthu zophatikizika bwino, zomwe zimapangitsa kuti makina azikhala ndi mphamvu zambiri.
ndi kulimba.
Ponena za kagwiritsidwe ntchito, HTPB yosungunuka imapeza ntchito m'mafakitale osiyanasiyana. Mu gawo la ndege, imagwiritsidwa ntchito popanga zomatira,
mankhwala ophikira m'miphika, ndi zotsekera zomangira ndi kutseka zigawo zofunika kwambiri. Kumamatira kwake kwabwino komanso kukana mankhwala kumapangitsa kuti ikhale chisankho chabwino kwambiri
ntchito zoyendera ndege komwe kudalirika ndi magwiridwe antchito ndizofunikira kwambiri.
Komanso, mumakampani opanga magalimoto, HTPB yosungunuka imagwiritsidwa ntchito popanga zokutira, zomatira, ndi zophimba za zida zamagetsi ndi
kugwiritsa ntchito pansi pa hood. Kutha kwake kupirira kukhudzana ndi madzi a magalimoto ndi nyengo zomwe zimakhalapo kumapangitsa kuti ikhale chinthu chokondedwa kwambiri pa magalimoto
ntchito zotsekera ndi zotetezera.
Kuphatikiza apo, HTPB yosungunuka imagwira ntchito mumakampani omanga popanga zokutira, zomatira, ndi zomatira zogwira ntchito kwambiri pa zomangamanga,
Kugwiritsa ntchito kwake mafakitale, ndi zomangamanga. Kulimba kwake kwambiri, kupirira nyengo, komanso kukana mankhwala kumapangitsa kuti ikhale chinthu chamtengo wapatali choteteza ndi kukulitsa
kulimba kwa zipangizo zomangira.
Pomaliza, Kuchuluka kwa epoxidation ya HTPB zimapangitsa kuti zinthu zosinthidwa zikhale ndi magwiridwe antchito abwino, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito m'njira zosiyanasiyana
m'mafakitale osiyanasiyana. Kulimba bwino kwa HTPB yosungunuka m'madzi, kukana mankhwala, kukhazikika kwa kutentha, komanso kuchedwa kwa moto kumapangitsa kuti ikhale chinthu chofunikira kwambiri.
kupanga zokutira zapamwamba, zomatira, zotsekera, ndi zinthu zopangidwa ndi zinthu zosiyanasiyana. Pamene kafukufuku ndi chitukuko cha kusintha kwa polima chikupitirira,
HTPB yopangidwa ndi epoxidized ikuyembekezeka kukhala ndi gawo lofunika kwambiri pakupanga zipangizo zogwirira ntchito bwino kwambiri m'mafakitale osiyanasiyana.
Timapereka mitundu yosiyanasiyana ya HTTPB, Kuchuluka kwa epoxidation ya HTPB, Gulu la Hydroxyl limodzi (HTPB), HTPB yopangidwa ndi hydrogenated...
