Hydroxyethyl 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.

Kubelesya Kupati
Imilimo yobile ya HEA ipa kuti ibe aampindu mumakwebo miingi:
Zivwumbyo aInki:
Zivwunisyo zitazungaani: Nchintu chipati loko mumyootokala, mumafakitali, amuzibelesyo. Kabunga ka hydroxyl kalaswaangana a melamine-formaldehyde naa polyisocyanate resins (mu PU coatings), kupa kuyuma kubotu, kukazyigwa kwamakemikalu, akukazya kubola.
Nzila Ziponya Aamumuni: Zibelesyegwa mbuli chintu chikonzya kumana akuswaanganya zintu zikonzya kusilika a UV/EB, ingi, azintu zyakunamatika. Nchintu chipati mukupanga ma urethane acrylates.
Zibelesyo zikwabilila mumuni azyakubelesya mumuni: Zibelesyegwa mukupanga zintu zikwabilila mumuni zyakusimba mapuleti azibelesyo zyamagesi (ma semiconductors, LCDs).
Zinamatika azintu zyakujala:
Kusumpula nguzu zyakunamatila kuzintu zisiyene, kubikkilizya abutale amapulasitiki.
Kuyungizya kuyuma kwa crosslink, kupa kuti kube kukazyigwa kupya, kukazyigwa kwamakemikalu, akuyuma kwakujatana muzibeela zyakunamatika zitakwe nguzu (PSAs).
Zisani & Nsinga:
Ibelesyegwa mbuli co-monomer muma fiber treatment agents antoomwe akuvwumba zizwaato kuchitila kuti zitanjili mumaanzi, zitanyonyooki, akuyuma.
Kubamba mapepa:
Zyakabikkilizyigwa mukupanga zyakuvwumba kuti ziyungizye manguzu aameenda akuyuma, kutazungaana amaanzi, akusimba.
Zibelesyo Zyaalubazu:
Industry yama Lubricant: Ibelekela mbuli musamu waakati-kati wakupanga mafuta aakusanzya azyakuyungizya.
Zibelesyo zyamagesi: Zibelesyegwa mbuli chintu chakugwisya maanzi mumubili mukubamba sampulu ya electron microscopy.
Chemistry yakulanga-langa: Ibeleka mbuli chemistry reagent alimwi mbuli chibeela muzintu zikonzya kusanganyigwa amaanzi.
Zibeela Zipati & Bubotu
Milimu yobile: Kabunga ka acrylate kalapa kuti kube copolymerization, mpawo kabunga ka hydroxyl kalakonzya kuchita kuti kube kujatana akucinca kwamakemikalu.
Kuyungizya kubeleka: Kupa kusima kupati, kukazyigwa amakemikalu, akukakatila kuma polymers aamamanino.
Kuchita zintu zyiingi: Zilafwambaana kuswaangana ama acrylates, methacrylates, styrene, vinyl acetate, acrylonitrile, azimwi.
Kukonzya kubelesegwa munzila zyiingi: Zilakonzya kubelesegwa munzila zyiingi zyakupanga ma polymerization, kubikkilizya a solution, emulsion, antoomwe a suspension polymerization.
Kubeleka kabotu: Kupa kuyaambele kupati mubube bwazintu nikuba kuti tazibikkilizyigwi pe (kanjikanji 2-10%).
Kuyuma Kusyoonto: Kubeleka mbuli chintu chigwasya loko muzintu zikonzya kusilikwa a radiation, kugwasya kuchesya kuyuma kakunyina kubelesya misamu iikola (VOCs).
Kubamba akubamba
Kupya Kwakubamba: Kobamba mubusena butontola, bujisi muuya mubotu. Kupya kwakubamba kuli akati ka 2°C a 25°C (36°F a 77°F). Kotantamuka kutontola akupya loko.
Inhibitor: Ilijisi MEHQ inhibitor kuchitila kutabilila kuchincha kwa polymerization. Chisinkilizyo chiyanda kuti kube muya mubotu kuti chibeleke; aboobo, kubamba mumulengalenga uutakwe chintu (nkokuti, Nitrogen padding) nchintu chipati loko kuti chikkale kabotu kwachiindi chilamfu.
Chibiya: Bikka muziyobwedo zijalilidwe kabotu zipangidwe abutale butakwe tombe, butale bujisi musamu wa phenolic, naa polyethylene. Kokwabilila kuzwa kumumuni.
Buumi bwakuyobweda: Kanjaanji myeezi iili 6 kusikila ku 12 kuzwa buzuba bwakupanga kuti yabikkwa muchiimo chili kabotu.
Kujata: Belesya kakuli muya uuzulide anzila zyakweendelezya. Kozyiba kuguma chikumba, meso, azyakusama. Amusame zibelesyo zyakulikwabilila (PPE), kubikkilizya amagilovu aatakonzyi kunjila mumakemikalu, magilazi aakukwabilila, alimwi azyakusama zyakulikwabilila.
