Hydroxypropyl acrylate ya xirhendzevutani
Nkatsakanyo wa Swikumiwa
Hydroxyethyl Acrylate (HEA) i monomer leyi tirhaka hi tindlela to hambana hambana naswona i xiaki xa nkoka eka tikhemikhali ta polymer. Yi na polymerizable acrylic double bond na ntlawa wa hydroxyl lowu hlamulaka eka molecule yin’we. Xivumbeko lexi xi pfumelela ku endla copolymerization hiku olova na nxaxamelo wo anama wa ti monomers loko yitlhela yi nghenelela eka ti crosslinking reactions. I mati lawa yanga erivaleni, lawa yangariki na muhlovo kuya eka yotshuka yo vonikela naswona yativeka hiku antswisa swinene swivumbeko swa matirhelo ya switirhisiwa swohetelela swa polymeric, hambi loko switirhisiwa hi nhlayo leyintsongo.

Hydroxypropyl Acrylate Switirhisiwa Leswikulu
Ntirho wa HPA wa swiyenge swimbirhi wu pfumelela ku tirhisiwa eka tiindasitiri to hambana. Ntirho wa yona wosungula iku tirha tani hi reactive diluent xikan’we na muphakeri wa ndzhawu ya crosslinking.
Swifunengeto & Tiinki:
Thermosetting Coatings: Yitirha tani hi co-monomer eka ti coatings ta mimovha, ti indasitiri, na ti coil. Yi crosslink na melamine, isocyanate kumbe epoxy resins, leswi endlaka leswaku kuva na ti films letingana ku tiya lokunene, ku lwisana na ti khemikhali, ku lwisana na mar, na ku hatima lokukulu.
Tisisiteme Ta Radiation-Curable: Ti tirhisiwa eka swifunengeto leswi tshungulaka hi UV/EB, ti-ink na swinamarheti. Ntlawa wa hydroxyl wu pfumelela ku endliwa ka ti urethane acrylates letingana swivumbeko leswi antswisiweke.
Photoresist Resins: Xiphemu xa nkoka eka ti photo-sensitive resins eka vumaki bya semiconductor na display.
Swinamarheti & Swipfalo:
Swi antswisa ku namarhela eka ti substrates leti tikaka ku ti boha kufana na tinsimbi na tipulasitiki leti tshunguriweke.
Swi ndlandlamuxa crosslink density, leswi yisaka eka ku antswisiwa ka ku tiya ka ku hisa, ku tiya ka tikhemikhali, na matimba yo hlangana eka swinamarheti leswi twaka ntshikelelo (PSAs) na swinamarheti swa xivumbeko.
Swiambalo & Tifibre:
Yitirhisiwa tani hi xitirhisiwa xo tshungula ti fibre ku cinca ti fibre ta synthetic, ku antswisa ku daya, swivumbeko swa antistatic, xikan’we naku tswongiwa ka ndzhongho.
Ti-Resin to Endliwa & Tipulasitiki:
Tanihi mucinci wa acrylic na ti resins tin’wana to endliwa, Hydroxypropyl acrylate yinyika ku tiya ka maxelo yale henhla, ku lwisana na ku khumbeka, na ku cinca cinca.
Hydroxypropyl Acrylate Switirhisiwa Swin’wana:
Ku lulamisiwa ka Maphepha: Tanihi xiphemu xa resin ya matimba na ku peta.
Tikhemikhali to Hlawula Mati: Ti tirhisiwa eka ku hlanganisiwa ka swisivela-mavabyi swa xikalo na ku bola.
Swiengeteri swa Lubricant: Switirha tani hi precursor eka swiantswisi swa viscosity index na swihangalasi.
Hydroxypropyl Acrylate Swihlawulekisi swa nkoka & Mimbuyelo
Reactivity ya kahle swinene: Ntlawa wa acrylate wu copolymerize hiku olova na nxaxamelo wo anama wa vinyl na acrylic monomers (xikombiso, methyl methacrylate, butyl acrylate, styrene, acrylonitrile).
Vuswikoti bya Matimba bya Crosslinking: Ntlawa wa pendant hydroxyl wu endla hi ku olova na diisocyanates, anhydrides, na amino resins (xikombiso, melamine), leswi endlaka leswaku ku endliwa ti network ta polymer leti tiyeke, ta swiphemu swinharhu.
Enhanced Adhesion: Swi hlohletela ku hlangana loku tiyeke eka ti substrates to hambana hambana.
Ku Antswisiwa Ka Ku Tiyisela: Swi hoxa xandla eka ku tiya loku xiyekaka eka tikhemikhali, swintshuxo, ku cinca ka maxelo na ku vonakala ka UV.
Ku tirhisiwa hi tindlela to hambana: Kunga tirhisiwa eka maendlelo yotala swinene ya polymerization, kukatsa na solution, emulsion, suspension, na bulk polymerization.
Ku tirha kahle ka Matirhelo: Swi tisa ku antswisiwa lokukulu eka swivumbeko swa xiendliwa xo hetelela hambi kuri eka swiyimo swale hansi swa matirhiselo (hi ntolovelo 1-10%).
Ku Khoma & Ku Hlayisa
Ku hlayisa: Hlayisa eka ndzhawu yo kufumela, ya munyama na leyi nghenaka kahle moya. Hlayisa swibye swi pfariwile swinene. Mahiselo lawa ya hlohleteriwaka ya vuhlayiselo yale xikarhi ka 15°C na 25°C (59°F na 77°F).
Inhibitor: Yina MEHQ (Methoxyphenol) tani hi polymerization inhibitor ku sivela self-polymerization hinkarhi wa nhlayiso naku fambisiwa. I swa nkoka ku hlayisa inhibitor leyi leswaku yita tiya.
Ku khoma: Papalata ku khumbana na kuhisa, swibalesa, malangavi lawa ya pfulekeke, na switirhisiwa swo tiya swa oxidizing. Tirhisa na moya lowu ringaneleke naswona ambala switirhisiwa leswi faneleke swo tisirhelela swa munhu hi xiyexe (PPE), ku katsa na magilavu lawa ya nga ngheniwiki hi tikhemikhali, tinghilazi ta vuhlayiseki, na swiambalo swo sirhelela.
Vutomi bya Shelf: Hi ntolovelo 12 wa tinhweti kusukela hi siku leri yi endliweke ha rona loko yi hlayisiwile ehansi ka swiyimo leswi ringanyetiweke.
