Hydroxypropyl acrylate
Kulanga-langa zintu
Hydroxyethyl Acrylate (HEA) nchintu chikonzya kubelesegwa munzila zyiingi mpawo nchintu chipati loko mukupanga ma polymer chemistry. Chili aama polymerizable acrylic double bond antoomwe a reactive hydroxyl group mu molecule yomwe. Bupange oobu bupa kuti chikonzye kunjila mu copolymerization antoomwe a monomers zyiingi mpawo chitola lubazu mu crosslinking reactions. Nchintu chisalala, chitakwe mubala kusikila kumubala wamubala wamubala wamubala wamubala wamubala wamubala wamubala wamubala wamubala wamubala wamubala wamubala wamubala wamubala wamubala wamubala wamubala wamubala wamubala wamubala wamubala wamubala wamubala wamubala wamubala wamubala wamubala wamubala wamubala wamubala wamubala wamubala wamubala wamubala uusalala pyu alimwi ulizyibidwe kuti ulasumpula kapati kubeleka kwazintu zyamamanino zya polymeric, nokuba kuti zyabelesyegwa mubunji busyoonto.

Hydroxypropyl Acrylate Main Applications
Imilimo yobile ya HPA ilazumizya kuti ibelesegwe mumakwebo aasiyene. Mulimu wayo mupati ngwakubeleka mbuli chintu chikonzya kumana mpawo chipa busena bwakuswaanganya.
Zivwumbyo aInki:
Zivwunisyo zitazungaani: Zibeleka mbuli co-monomer mumyootokala, mumafakitali, amuzivwunisyo zyama coil. Ilaswaanganya a melamine, isocyanate, naa epoxy resins, kupa kuti kube mafilimu aayumu kapati, aatakonzyi kulwana misamu, aatakonzyi kunyonyooka, alimwi aamweka-mweka kapati.
Nzila Ziponya Aamumuni: Zibelesyegwa muzisani zikonzya kusilika a UV/EB, ingi, azintu zyakunamatika. Kabunga ka hydroxyl kazumizya kupanga ma urethane acrylates ajisi zintu zisumpukide.
Zibelesyo zya Photoresist: Nchintu chipati muma resini aakonzya kumvwika mumuni aabelesyegwa mukupanga zintu zibelesyegwa kupanga zintu zitondezya mumuni.
Zinamatika azintu zyakujala:
Kusumpula kunamatila kuzintu zikatazya kujatana mbuli nsimbi amapulasitiki aasilikwa.
Kuyungizya kuyuma kwa crosslink, kupa kuti kube kukwabililwa kupya, kukazyigwa kwamakemikalu, akuyuma kwakujatana muma pressure-sensitive adhesives (PSAs) alimwi a structural adhesives.
Zisani & Nsinga:
Ibelesyegwa mbuli musamu wakusilisya ntambo kuchincha ntambo zyakupanga, kuchita kuti ntambo zibe kabotu, zikwabilila, akunyona maanzi.
Ma resini aakupanga apulasitiki:
Mbuli chintu chikonzya kuchincha ma acrylic azimwi zintu zyakupanga, Hydroxypropyl acrylate ilakwabilila kuchiindi chilamfu, kukwabililwa kukutyompokelwa, akukonzya kuchincha.
Hydroxypropyl Acrylate Zimwi Zibelesyo:
Kubamba mapepa: Mbuli chintu chiyumu cha resin antoomwe akuvwumba.
Makemikalu aakusalazya maanzi: Abelesyegwa mukupanga misamu iilesyela kubola.
Ziyungizyo zyakusanzya: Zibeleka mbuli nzila yakusumpula busani bwamubili akumwaika.
Hydroxypropyl Acrylate Zibeela Zipati Abubotu
Kuchita kabotu: Kabunga ka acrylate kalafwambaana kuswaangana a vinyl a acrylic monomers (nkokuti, methyl methacrylate, butyl acrylate, styrene, acrylonitrile).
Nguzu zyakuswaanganya: Kabunga ka pendant hydroxyl kalakonzya kuswaangana a diisocyanates, anhydrides, antoomwe a amino resins (nkokuti, melamine), kupa kuti kube kupanga ma polymer networks aayumu, aajisi zibeela zyotatwe.
Kuyungizya kujatana: Kusumpula kujatana kuyumu kuzintu zisiyene-siyene.
Kuyungizya Kuyuma: Kugwasya kukazyigwa kapati kumakemikalu, zintu zipa kuti zintu zibe kabotu, kuchincha kwamvwula, amumuni wa UV.
Kukonzya kubelesegwa munzila zyiingi: ilakonzya kubelesegwa munzila zyiingi zyakupanga ma polymerization, kubikkilizya a solution, emulsion, suspension, antoomwe a bulk polymerization.
Kuchita obotu: Kupa kusumpuka kupati muzintu zyakumamanino nikuba kuti tazibelesyegwi pe (kanjikanji 1-10%).
Kubamba akubamba
Kubamba: Kobamba mubusena butontola, busiya, alimwi bujisi muuya mubotu. Bikka ziyobwedo kazijalilidwe kabotu. Kupya kwakubamba kuli aakati ka 15°C a 25°C (59°F a 77°F).
Inhibitor: Ilijisi MEHQ (Methoxyphenol) mbuli chintu chilesya kupanga ma polymerization kuchitila kutabilila kulipolymerization muchiindi chakuyobola akutola. Nchintu chipati kubamba chintu eechi kuti chikkale kabotu.
Kujata: Kotantamuka kupya, mulilo, mulilo uuvwilima, azintu zipa kuti kube muya mubotu. Belesya kakuli muya uuzulide mpawo usame zibelesyo zyakulikwabilila (PPE), kubikkilizya magilovu aatakonzyi kunjililwa misamu, magilazi aakukwabilila, azyakusama zyakulikwabilila.
Buumi bwakuyobweda: Kanjaanji myeezi ilikkumi ayibili kuzwa buzuba bwakupanga kuti yabikkwa muchiimo chili kabotu.
