nkhani

2-hydroxyethyl methacrylate(HEMA) ndi organic polymerization monomer yopangidwa ndi zomwe ethylene oxide (EO) ndi methacrylic acid (MMA), yomwe ili ndi magulu osagwirizana mkati mwa molekyulu.Hydroxyethyl methacrylate ndi mtundu wamadzimadzi wopanda mtundu, wowonekera, komanso woyenda mosavuta.Zosungunuka mu zosungunulira za organic.Kusakaniza ndi madzi.

Kugwiritsa ntchito kwa HEMA

1. Amagwiritsidwa ntchito makamaka posintha ma resin ndi zokutira.Copolymerization ndi ma monomers ena a acrylic amatha kupanga ma resins a acrylic okhala ndi magulu a hydroxyl yogwira pamaketani am'mbali, omwe amatha kukumana ndi esterification ndi crosslinking reaction, synthesize insoluble resins, adhesion adhesion, and angagwiritsidwe ntchito ngati wothandizira CHIKWANGWANI.Imakhudzidwa ndi melamine formaldehyde (kapena urea formaldehyde) utomoni, epoxy resin, ndi zina zotero kuti apange zokutira zigawo ziwiri.Kuwonjezera pa utoto wapamwamba wamagalimoto amatha kukhalabe ndi galasi lowala kwa nthawi yayitali.Itha kugwiritsidwanso ntchito ngati zomatira pazovala zopangira komanso ma polymer monomers azachipatala.

2. HEMA imagwiritsidwa ntchito popanga utomoni wa zokutira, topcoat zamagalimoto ndi zoyambira, komanso ma resin a photopolymer, matabwa osindikizira, inki, gel (magalasi olumikizirana) ndi zokutira zakuthupi, ma electron microscopy (TEM) ndi ma microscope (LM) ophatikizira. reagents, makamaka zitsanzo za hydration za "malo omvera antigen".Madzi oyera ngati, omata, owonda kuposa madzi, komanso osavuta kulowa kuposa utomoni uliwonse kapena monomer.Makamaka ntchito pa mafupa, chichereŵechereŵe, ndi zovuta kulowa zomera zimakhala.

3. Makampani apulasitiki amagwiritsidwa ntchito popanga ma acrylic resins okhala ndi magulu a hydroxyl yogwira ntchito.Makampani okutira amagwiritsidwa ntchito limodzi ndi epoxy resins, diisocyanates, melamine formaldehyde resins, etc. kuti apange zokutira ziwiri.Malo opangira mafuta amagwiritsidwa ntchito ngati chowonjezera pakutsuka mafuta.Makampani opanga zamagetsi amagwiritsidwa ntchito ngati chotsitsa madzi m'thupi la ma microscopes a elekitironi.Zomatira zomwe zimagwiritsidwa ntchito m'makampani opanga nsalu kupanga nsalu.Amagwiritsidwa ntchito ngati reagent yamankhwala mu analytical chemistry.Kuphatikiza apo, imagwiritsidwanso ntchito ngati chophatikizira chosungunuka m'madzi popanga zida zamankhwala za polima, zokutira za thermosetting, ndi zomatira.

Tsogolo laHEMA:

Ofufuza zamakampani anena kuti chifukwa chakuchita bwino kwambiri, hydroxyethyl methacrylate pakali pano ikufunika kwambiri pakufunsira, makamaka pankhani ya zokutira zamankhwala komanso zomaliza, zomwe zikuyembekezeka.Pali mwayi wachitukuko pamsika wamtsogolo wa hydroxyethyl methacrylate. Kumbali yofunikira: Ndikukula kwachangu kwa kufunikira m'magawo monga zokutira ndi zomatira, kugwiritsa ntchito 2-hydroxyethyl methacrylate kukuchulukirachulukira. Mwaukadaulo,HEMAUkadaulo wopanga ndiukadaulo wopanga pulasitiki ungaphunzire kuchokera kwa wina ndi mnzake potengera kapangidwe, zida, njira, ndi magwiridwe antchito. Pankhani ya unyolo wamafakitale: chitukuko chamankhwala apamwamba kwambiri a hydroxyethyl methacrylate amatha kulumikiza kumtunda kwa methacrylic acid ndi zida za ethylene oxide, komanso zida zokutira zotengera madzi kunsi kwa mtsinje.Nthawi yomweyo, hydroxyethyl methacrylate ndi chinthu chofunikira kwambiri pabizinesi yapamtunda, kuwonetsetsa kuti pali ma monomers ofunikira pabizinesi yakumtunda, kukulitsa unyolo wamakampani, ndikuwonjezera mtengo wazinthu. .Pofuna kugwirizanitsa gawo lake la msika, kampaniyo yaganiza zowonjezera mphamvu zake zopangira zida zoyamba ndi kuyeretsa njira yoyamba yowononga madzi kuti iwonjezere mphamvu yake yopanga.
