I-Hydroxypropyl acrylate
Isishwankathelo seMveliso
I-Hydroxyethyl Acrylate (HEA) yi-monomer esebenza ngeendlela ezahlukeneyo kwaye isisiseko sokwakha kwi-polymer chemistry. Ine-polymerizable acrylic double bond kunye neqela le-reactive hydroxyl kwi-molecule enye. Olu lwakhiwo luyivumela ukuba ikwazi ukungena kwi-copolymerization ngokulula kunye noluhlu olubanzi lwee-monomers ngelixa ithatha inxaxheba kwii-crosslinking reactions. Lulwelo olucacileyo, olungenambala ukuya koluphuzi olukhanyayo kwaye lwaziwa ngokuphucula kakhulu iipropati zokusebenza kweemveliso zokugqibela ze-polymeric, nokuba zisetyenziswa ngobuninzi obuncinci.

Izicelo eziphambili zeHydroxypropyl Acrylate
Ukusebenza okumbaxa kwe-HPA kuvumela ukuba isetyenziswe kumashishini ahlukeneyo. Umsebenzi wayo oyintloko kukusebenza njengomxubi ophendulayo kunye nomboneleli wewebhusayithi odibanisayo.
Iingubo kunye nee-Inks:
Iingubo zeThermosetting: Zisebenza njenge-co-monomer kwiingubo zeemoto, zemizi-mveliso, neze-coil. Zidibana ne-melamine, isocyanate, okanye ii-epoxy resins, nto leyo ephumela kwiifilimu ezinobunzima obugqwesileyo, ukumelana neekhemikhali, ukumelana ne-mar, kunye ne-gloss ephezulu.
Iinkqubo Ezinyangekayo Ngemisebe: Zisetyenziswa kwiingubo, kwii-inki, nakwizinto zokuncamathelisa ezinokunyangeka ze-UV/EB. Iqela le-hydroxyl livumela ukwenziwa kwee-acrylates ze-urethane ezineempawu eziphuculweyo.
IiResins zePhotoresist: Inxalenye ephambili kwiiresins ezibuthathaka kwifoto kwimveliso ye-semiconductor kunye ne-display.
Izinto zokuncamathelisa kunye nezitywini:
Iphucula ukunamathela kwi-substrates ezinzima ukubopha ezifana neentsimbi kunye neeplastiki ezilungisiweyo.
Iphucula uxinano lwe-crosslink, nto leyo ekhokelela ekuphuculeni ukumelana nobushushu, ukumelana neekhemikhali, kunye namandla okubambisana kwiiglue ezibuthathaka kuxinzelelo (ii-PSA) kunye neeglue zesakhiwo.
Amalaphu kunye neeFiber:
Isetyenziswa njengearhente yonyango lwefayibha ukutshintsha iifayibha ezenziweyo, ukuphucula ukudaywa, iipropati ezichasene nokuma, kunye nokufunxwa komswakama.
IiResins kunye neePlastiki zokwenziwa:
Njengesiguquli se-acrylic kunye nezinye ii-resin zokwenziwa, i-Hydroxypropyl acrylate inika ukumelana okuphezulu kwemozulu, ukumelana nempembelelo, kunye nokuguquguquka.
Ezinye izicelo zeHydroxypropyl Acrylate:
