Hydroxyethyl acrylate
Neno wi piny ma jucul
Hydroxyethyl Acrylate (HEA) ubedo monomer ma tiyo ku yore madwong man piny ma pire tek i polymer chemistry. Etiye ku polymerizable acrylic double bond man reactive hydroxyl group i molecule acel. Kit yub eni miyo ecopo timo copolymerization ku monomers matung tung man bende etimo crosslinking reactions. Etiye piny ma leng, ma rangi pare nya nya nya man ungeyere pi medo tic pa piny ma juyubu ku polymeric, kadi nangu jutiyo kudu manok.

Tic madongo
Tic ario pa HEA miyo ebedo piny ma pire tek ikind tic mapol:
Coatings & Inks:
Thermosetting Coatings: A primary monomer in automotive, industrial, and appliance coatings. Dul pa hydroxyl ucungo ku melamine-formaldehyde nyo polyisocyanate resins (i PU coatings), ma miyo bedo matek, kero mi juku kemikol, man kero mi juku.
Radiation-Curable Systems: Jutiyo kudu calu reactive diluent man crosslinker in UV/EB-curable coatings, inks, man adhesives. Etiye piny ma pire tek iyubu pa urethane acrylates.
Photoresists & Photoreactive Polymers: Jutiyo kudu pi yubu photoresist resins pi goyo piny man jam tic (semiconductors, LCDs).
Piny ma mako man ma mako:
Medu tego pa mako pa piny matung tung, ikinde utiye cuma man plastik.
Medu rwom pa crosslink, ma kelo kero maber mi juku lyethu, kero mi juku kemikol, man kero mi mako piny i structural man pressure-sensitive adhesives (PSAs).
Jam tela & Fibers:
Jutiyo kudu calu co-monomer i fiber treatment agents man bongo ma jukubo pi miyo pii kud i pii, rwinyo ma rwinyo, man bedo ma rii.
Tic ku waraga:
Ju medo i kit ma juyubu kudu pi medo tego pa pii man ma muthwo, gwoko pii, man goyo piny.
Tic ma pire tek:
Lubricant Industry: Tiyu calu kemikol ma jutiyo kudu pi yubu detergent man dispersant additives.
Jam tic mi mac: Jutiyo kudu calu piny ma jwigo pii i electron microscopy.
Analytical Chemistry: Tiyu calu piny ma jutiyo kudu pi kemikol man calu piny ma jutiyo kudu i pii.
Lembe ma pire tek man bero
Tic ario: Dul pa acrylate weko copolymerization, man dul pa hydroxyl weko crosslinking man loko piny.
Tic maber: Miyo kero maber, tek pa kemikol, man mako pa polymers.
Reactivity ma malo: Copolymerizes mayot ku acrylates, methacrylates, styrene, vinyl acetate, acrylonitrile, man mukende mapol.
Ber pa tic: Ber pi tic matung tung mi polymerization, ikinde utiye solution, emulsion, man suspension polymerization.
Tic maber: Kelo aloka loka madit ikum kit pa piny kadi i rwom ma piny (ma pol kare 2-10%).
Viscosity ma piny: Tiyu calu reactive diluent maber in radiation-curable systems, ma konyo ni dwoko piny viscosity pa formulation labongo tic ku volatile organic compounds (VOCs).
Gwoko man gwoko
Temperature mi gwoko: Gwoko kama ngic, kama yamo wok iye maber. Piny maber mi gwoko piny utiye ikind 2°C ku 25°C (36°F ku 77°F). Kur ngico man lyethu ma malu.
Inhibitor: Utie ku MEHQ inhibitor mi juku polymerization ma wok kende kende. Inhibitor mito bedo pa oxygen kara etim tic; kumeno, gwoko piny i the yamo ma timo ngo tic (calu, Nitrogen padding) piretek pi bedo maber pi kare malac.
Ajeni: Keth i ajeni ma cego maber ma juyike ku steel ma nyai ungo, phenolic resin-lined steel, nyo polyethylene. Gwok kud i ler.
Kwo pa piny: Pol kare dwi 6 ku 12 nicaku i ceng ma juyubu kudu ka jugwoko i yore maber.
Tiyu kude: Ti ku yamo maber man ku jam tic mi gedo. Kur mako adila, wang, man kendi. Kend jam gwoko kum peri (PPE), ikinde gloves ma kemikol copo rwinyo ngo, safety goggles, man bongo mi gwoko kum.
