Hydroxyethyl acrylate
Thilri zohfelnak
Hydroxyethyl Acrylate (HEA) cu a phunphun in rian a ttuan khomi monomer a si i polymer chemistry ah a biapi tukmi saknak thilri a si. Molecule pakhat chung ah polymerizable acrylic double bond le reactive hydroxyl group a ngei. Hi sining nih hin monomers phunphun he fawi tein copolymerization tuah khawhnak a pek i cu pin ah crosslinking reactions zongah aa tel ve. A fiangmi, rong ngei lo in a senmi tiang a si i a tlawmte hman hmanh ah a donghnak polymeric thilri hna i riantuan ning a tthanchoter ngaingai tiah theih a si.

Radiation-Curable Systems: UV/EB-curable coatings, inks, le adhesives ah reactive diluent le crosslinker ah hman a si. Urethane acrylates sernak ah a biapi tukmi thilri a si.
Photoresists & Photoreactive Polymers: Cauk chuahnak plate le electronics (semiconductors, LCDs) caah photoresist resins sernak ah hmanmi.
Hnawmhnak le kharnak:
Thir le plastic telh in thilri phunphun ah i hngatchannak thazaang a tthanter.
Crosslink density a ṭhanchoter, cu nih cun a ṭha deuhmi lumnak doh khawhnak, chemical doh khawhnak le sining le hneknak-sensitive adhesives (PSAs) ah aa pehtlaimi ṭhawnnak a chuahter.
Puan le hri:
Fiber thlopnak sii le puan thuhnak ah ti doh khawhnak, tlik khawhnak le fek tein um khawhnak caah co-monomer ah hman a si.
Cauk thlennak:
A lum le a ro thazaang, ti a tei khawhnak le chuah khawhnak tthanchoter awkah hnipuan sernak ah aa tel.
Special Application:
Lubricant Industry: Thil thianhnak le tthencheunak thilri sernak caah chemical karlak ah rian a ttuan.
Electronics: Electron microscopy sample timhtuahnak ah ti tlawmternak thilri ah hmanmi.
Analytical Chemistry: Chemical reagent le ti he aa cawhmi thilri hna ah aa telmi thilri pakhat bantukin rian a ttuan.
A Biapimi Thilri le Ṭhathnemnak
Riantuannak pahnih: Acrylate phu nih copolymerization a tuah khawh, cun hydroxyl phu nih cun crosslinking le chemical thlennak a tuah khawh.
A tthanchomi riantuan ning: A ttha tukmi fek tein um khawhnak, chemical doh khawhnak le a donghnak polymers ah aa hngat khawhnak a pek.
Reactivity sang: Acrylates, methacrylates, styrene, vinyl acetate, acrylonitrile le a dangdang hna he fawi tein aa fonh khawh.
A phunphun in hman khawhnak: Polymerization phunphun caah aa tlak, cu ah cun cawhmi, cawhmi, le hnimhnak polymerization aa tel.
Riantuannak tthatnak: A tlawmmi luhternak (a tlangpi in 2-10%) hmanh ah thilri sining ah tthanchonak nganpi a chuahpi.
A tlawmmi tthawnnak: Radiation-curable system ah a ttha ngaimi reactive diluent bantukin rian a ttuan, a tthawngmi thilnung (VOCs) hman loin sermi tthawnnak zorternak ah a bawmh.
Tawlrelnak le Chiahnak
Chiahnak Lungthawhnak: A kikmi, thli a lut khomi hmun ah chiah. Chiahnak ding caah ruahnak cheuhmi lumnak cu 2°C le 25°C (36°F le 77°F) karlak a si. A lum tukmi le a lin tukmi kha hrial.
Inhibitor: Mah tein a chuakmi polymerization khamnak caah MEHQ inhibitor aa tel. Inhibitor nih riantuan khawhnak dingah oxygen a herh; cucaah, a cawlcang lomi thli (tahchunhnak ah, Nitrogen padding) tangah chiah cu caan saupi fek tein um khawhnak caah a herh.
Thil chiahnak kuang: Thir thir, phenolic resin-lined thir, asiloah polyethylene in sermi fek tein kharmi kuang chungah chiah. Ceunak in huhphenh.
Caan sauhnak: A tlangpi in ser ni in thla 6 in thla 12 karlak a si, a ttha mi thil sining tangah chiah a si.
Hmannak: Thli luhchuahnak le engineering uknak ttha he hman. Vun, mit le thilthuam he i tawngh hrial. Aa tlakmi pumpak kilvennak thilri (PPE) i hruk, cu ah cun chemical a kham khomi kutdonghrolh, himnak mithmaihuh, le kilvennak thilthuam hna aa tel.
