Hydroxypropyl acrylate
Pfupiso yeChigadzirwa
Hydroxyethyl Acrylate (HEA) imonomer inoshanda zvakasiyana-siyana uye chinhu chikuru mu polymer chemistry. Ine polymerizable acrylic double bond uye reactive hydroxyl group mumorekuru imwe chete. Chimiro ichi chinoibvumira kuti ikwanise kupinda mu copolymerization nyore nyore nemarudzi akasiyana-siyana emamonomer ukuwo ichibatanidzwawo mu crosslinking reactions. Imvura yakajeka, isina ruvara kusvika kune yero uye inozivikanwa nekuwedzera zvakanyanya mashandiro ezvigadzirwa zve polymeric zvekupedzisira, kunyangwe zvikashandiswa zvishoma.

Mashandisirwo Makuru eHydroxypropyl Acrylate
Mashandiro maviri eHPA anoibvumira kushandiswa mumaindasitiri akasiyana-siyana. Basa rayo guru nderekushanda semusanganiswa wemagetsi uye mupi wewebhusaiti anobatanidza.
Mapendi & Inki:
Machira eThermosetting: Anoshanda se co-monomer muzvipfeko zvemotokari, zvemaindasitiri, uye zve coil. Anobatanidzwa ne melamine, isocyanate, kana epoxy resins, zvichikonzera mafirimu ane kuomarara kwakanaka, kuramba makemikari, kuramba mar, uye kupenya kwakanyanya.
Masisitimu Anorapika Nemwaranzi: Anoshandiswa muUV/EB-coatings, inks, uye glues zvinorapika. Boka rehydroxyl rinobvumira kugadzirwa kweurethane acrylates dzine hunhu hwakavandudzwa.
MaResins ePhotoresist: Chinhu chakakosha mumaresins anonzwa foto ekugadzira masemiconductor uye display.
Zvinonamira & Zvinovhara:
Inovandudza kunamira kune zvinhu zvakaoma kubatana zvakaita sesimbi nemapurasitiki akagadziriswa.
Inosimudzira huwandu hwe crosslink, zvichiita kuti pave nekusimba kwekupisa, kusasimba kwemakemikari, uye kusimba kwekubatana muma glues anonzwa kumanikidzwa (PSAs) uye ma structural adhesives.
Machira & Fibers:
Inoshandiswa semushonga wekugadzirisa fiber kugadzirisa fiber dzakagadzirwa, kuvandudza kudhaya, hunhu hunodzivirira static, uye kunyudzwa kwehunyoro.
MaResin & Mapurasitiki Ekugadzira:
Senzira yekugadzirisa acrylic nedzimwe resins dzekugadzira, Hydroxypropyl acrylate inopa simba rekudzivirira mamiriro ekunze, rekudzivirira kukanganiswa, uye rinochinjika.
Zvimwe Zvishandiso: Hydroxypropyl Acrylate
Kugadzira Mapepa: Sechinhu chinowedzera simba resin uye chinodzivirira.
Makemikoro Ekurapa Mvura: Anoshandiswa mukugadzirwa kwezvinodzivirira ngura nekukura kweganda.
Zvinowedzerwa pamafuta: Zvinoshanda senzira yekuvandudza uye kuparadzanisa viscosity index.
Zvinhu Zvikuru zveHydroxypropyl Acrylate uye Mabhenefiti
Kuita Zvakanaka Kwazvo: Boka reacrylate rinoita copolymer nyore nyore ne vinyl uye acrylic monomers dzakasiyana-siyana (semuenzaniso, methyl methacrylate, butyl acrylate, styrene, acrylonitrile).
Kugona Kubatanidza Zvinhu Nesimba: Boka re pendant hydroxyl rinoita nyore nyore ne diisocyanates, anhydride, uye amino resins (semuenzaniso, melamine), zvichiita kuti pave ne network dze polymer dzakasimba, dzine mativi matatu.
Kunamira Kwakawedzerwa: Kunosimudzira kubatana kwakasimba kune substrates dzakasiyana-siyana.
Kuvandudza Kugara Kwenguva Refu: Kunobatsira pakudzivirira zvakanyanya makemikari, zvinonyungudutsa, mamiriro ekunze, uye chiedza cheUV.
Kuchinja-chinja: Inogona kushandiswa mumhando dzakasiyana-siyana dzemaitiro e polymerization, kusanganisira mhinduro, emulsion, suspension, uye bulk polymerization.
Kushanda Nesimba: Kunopa kuvandudzwa kukuru muhunhu hwechigadzirwa chekupedzisira kunyangwe pakushandiswa kwakaderera (kazhinji 1-10%).
Kubata & Kuchengeta
Kuchengetera: Chengeta munzvimbo inotonhorera, ine rima, uye ine mhepo inofefetera zvakanaka. Chengeta midziyo yakavharwa zvakanaka. Tembiricha inokurudzirwa yekuchengetedza iri pakati pe15°C ne25°C (59°F ne77°F).
Inhibitor: Ine MEHQ (Methoxyphenol) semushonga unodzivirira polymerization kudzivirira self-polymerization panguva yekuchengetwa nekutakurwa. Zvakakosha kuchengetedza mushonga uyu kuti ugare wakasimba.
Kubata: Dzivisa kusangana nekupisa, zvipfungaidzo, marimi emoto akavhurika, uye zvinhu zvine simba zvinooxidating oxidation. Shandisa nemhepo yakakwana uye pfeka midziyo yekudzivirira yakakodzera (PPE), kusanganisira magirovhosi asingapindi makemikari, magirazi ekuchengetedza, uye mbatya dzekudzivirira.
Hupenyu hweSherufu: Kazhinji mwedzi gumi nemiviri kubva pazuva rekugadzirwa kana yakachengetwa pasi pezvinodiwa.
