I-Hydroxypropyl acrylate
Ukuhlolisisa komkhiqizo
I-Hydroxyethyl Acrylate (HEA) yi-monomer esebenza ngeendlela ezihlukahlukeneko begodu yinto eqakathekileko yokwakha ikhemikhali ye-polymer. Ine-polymerizable acrylic double bond kanye ne-reactive hydroxyl group ku-molecule efanako. Isakhiwo lesi sivumela bona lula bona ibe ne-copolimerization ngeenhlobo ezinengi zama-monomer lokha nayihlanganyela ekuphenduleni kokuhlanganisa. Yinto ekhanyako, engenambala ukuya ephuzi elikhanyako begodu yaziwa ngokuthuthukisa khulu ukusebenza kwemikhiqizo yokugcina ye-polymeric, ngitjho nanyana isetjenziswa ngamanani amancani.

Iinsetjenziswa ezikulu ze-Hydroxypropyl Acrylate
Ukusebenza kabili kwe-HPA kuvumela bona isetjenziswe emabubulweni ahlukahlukeneko. Umsebenzi wayo omkhulu kusebenza njenge-diluent esebenzako kanye nomhlinzeki wendawo yokuhlanganisa.
Ukugcoba nama-inki:
Ukutjhisa: Kusebenza njenge-co-monomer eenkoloyini, emabubulweni, kanye namakhoyili. Ihlangana ne-melamine, i-isocyanate, nofana i-epoxy resins, okwenza bona kube namafilimu anobunzima obuhle khulu, ukujamelana namakhemikhali, ukujamelana nama-mar, kanye nokukhanya okuphezulu.
IinHlelo ezilapheka ngemisebe: Isetjenziswa eendleleni ezilapha nge-UV/EB, ama-inki, kanye nama-adhesive. Isiqhema se-hydroxyl sivumela ukwakhiwa kwama-urethane acrylates anezinto ezithuthukisiweko.
Ama-Photoresist Resins: Ingcenye eqakathekileko kuma-photo-sensitive resins wokukhiqiza ama-semiconductor nama-display.
Iinamatheliso nezivala:
Yenza ngcono ukunamathelana kwezinto ezinzima ukuzibophelela njengeensimbi namapulasitiki ahlanjululweko.
Ikhuphula ukuminyana kwe-crosslink, okurholela ekuthuthukisweni kokujamelana nokutjhisa, ukujamelana namakhemikhali, nokuqina kokuhlangana ema-adhesives azwela ukugandeleleka (ama-PSA) kanye nama-adhesives wesakhiwo.
Iindwangu nemicu:
Isetjenziswa njenge-ejenti yokuhlanza ifayibha ukutjhugulula ifayibha eyenziwe ngabantu, ukwenza ngcono ukudaya, izakhiwo zokulwisana nobujamo, nokumuncwa komswakama.
Ama-resin wokwenziwa namaplastiki:
Njengomtjhugululi we-acrylic namanye ama-resin wokwenziwa, i-Hydroxypropyl acrylate inikela ukujamelana nobujamo bezulu, ukujamelana nokutjhuguluka, nokutjhuguluka.
I-Hydroxypropyl Acrylate Ezinye Iinsetjenziswa:
Ukusetjenziswa kwamaphepha: Njenge-resin yamandla kanye nengcenye yokugcoba.
Amakhemikhali wokuhlanza amanzi: Asetjenziswa ekuhlanganisweni kweenqhema ezivimbela ukugqwala.
Iinthako zokuthambisa: Zisebenza njengesandulela sokuthuthukisa inkomba ye-viscosity kanye nokusabalalisa.
Iimpawu eziqakathekileko ze-Hydroxypropyl Acrylate
Ukuphendula okuhle khulu: Isiqhema se-acrylate sihlangana lula nge-vinyl ne-acrylic monomers (isib., i-methyl methacrylate, i-butyl acrylate, i-styrene, i-acrylonitrile).
Ikhono elinamandla lokuhlanganisa: Isiqhema se-hydroxyl esilengako siphendula lula nama-diisocyanates, ama-anhydrides, kanye nama-amino resins (isib., i-melamine), okwenza bona kwakhiwe amanethiwekhi we-polymer ahlala isikhathi eside, amathathu.
Ukunamathela okuthuthukisiweko: Kukhuthaza ukunamathelana okuqinileko eendaweni ezihlukahlukeneko.
Ukuthuthukiswa kokuqina: Kufaka isandla ekujameleni okuphuma phambili kumakhemikhali, iinsombululo, ukutjhuguluka kwezulu, kanye nokukhanya kwe-UV.
Ukusetjenziswa: Ingasetjenziswa eenkambisweni ezinengi zokwenza amapholimera, okufakahlangana isisombululo, ukuhlanganiswa, ukumiswa, kanye nokwenza amapholima ngobunengi.
Ukusebenza kuhle: Kuletha ukuthuthukiswa okukhulu ekwakhiweni komkhiqizo wokugcina ngitjho nasezingeni eliphasi lokusetjenziswa (ngokuvamileko 1-10%).
Ukuphathwa nokugcina
Ukubulunga: Beka endaweni epholileko, emnyama, begodu enomoya omuhle. Gcina iintjalo zivalwe kuhle. Izinga lokutjhisa eliphakanyisiweko lokugcina liphakathi kwe-15°C kanye ne-25°C (59°F kanye ne-77°F).
I-Inhibitor: Iqukethe i-MEHQ (Methoxyphenol) njenge-polymerization inhibitor ukukhandela ukuzi-polymerization ngesikhathi sokugcina nokuthuthwa. Kuqakathekile ukugcina isivimbeli ukuze sizinze.
Ukuphatha: Balekela ukuthintana nomtjhiso, iinhlansi, amalangabi avulekileko, kanye nama-ejenti aqinileko we-oksijini. Sebenzisa ngendlela eyaneleko yokungenisa umoya begodu ugqoke izinto zokuzivikela ezifaneleko (i-PPE), okufakahlangana amagilavu angathathwa makhemikhali, amagilasi wokuvikela, kanye nezambatho zokuzivikela.
Isikhathi sokuphila: Ngokuvamileko iinyanga ezili-12 ukusuka ngelanga lokukhiqiza lokha nayibekwa ngaphasi kwemibandela ephakanyisiweko.
