Igikoresho c'amazi
Incamake y'igicuruzwa
Hydroxyethyl Acrylate (HEA) ni ikintu gikora cane kandi ni ikintu nyamukuru co kwubaka mu buhinga bwa shimi bw’ibintu vyinshi. Igira ubucuti bubiri bw’amazi bushobora guhinduka (polymérisation) n’umugwi w’amazi (hydroxyl) ushobora guhinduka mu mubiri umwe. Ivyo bituma ishobora gukorana n’ibindi bihimba vyinshi vy’umubiri (monomeres) mu gihe kandi igira uruhara mu bikorwa vy’ugukorana n’ibindi binyabuzima. Ni amazi agaragara, atagira ibara canke umuhondo ukeye kandi azwi ko yongera cane ubushobozi bw’ibintu vy’iherezo vy’ivyuma vy’ivyuma, mbere n’igihe bikoreshwa mu rugero rutoyi.

Ibikorwa nyamukuru
Ibikorwa bibiri vya HEA bituma bihambaye cane mu bikorwa vyinshi:
Ivyo gupfuka n'amarangi:
Ivyuma bipfuka ubushuhe: Ni ikintu nyamukuru gikoreshwa mu gupfuka imodoka, inganda n’ibikoresho. Iryo tsinda ry’amazi ryitwa hydroxyl rifatanya n’amaresine ya melamine-formaldehyde canke polyisocyanate (mu bipfukisho vya PU), bikaba bitanga ubukomezi bwiza cane, ubushobozi bwo guhangana n’imiti, n’ubushobozi bwo guhangana n’ibintu bihumanye.
Ivyuma bishobora gukira n’imishwarara: Bikoreshwa nk’ikintu gishobora gutuma amazi agira ubushobozi bwo gukira no gukorana n’ibindi mu bikoresho bishobora gukira n’imishwarara ya UV/EB, mu bipfukisho vy’amarangi no mu bifatanya. Ni ikintu nyamukuru mu guhingura ivyuma vyitwa urethane acrylates.
Ivyuma bishobora guhangana n’umuco n’ivyuma bishobora guhangana n’umuco: Bikoreshwa mu guhingura ivyuma bishobora guhangana n’umuco vyo gucapura amasahani n’ibikoresho vy’ubuhinga bwa none (semiconductors, LCDs).
Ivyo kwifatanya n'ivyo gukingira:
Itera imbere mu gukomera kw’ibintu bitandukanye, harimwo n’ivyuma n’amapulasitike.
Itera imbere mu guhangana n’ubushuhe, guhangana n’imiti, n’ubukomezi bwo gufatanya mu bikoresho vy’imibumbe n’ivy’umukazo (PSAs).
Impuzu n'inyuguti:
Ikoreshwa nk’ikintu kimwe (co-monomer) mu bikoresho vyo gusukura intsinga no mu bikoresho vyo gupfuka ibitambaro kugira ngo bishobore guhangana n’amazi, guhangana n’imitsi, n’ugukomera.
Gutunganya impapuro:
Ishirwa mu bikoresho vyo gupfuka kugira ngo bikomeze gukomera iyo bitose canke vyumye, ntibishobore guterwa n’amazi, kandi bishobore gucapwa.
Ibisabwa vyihariye:
Inganda y’amavuta: Ikora nk’ikintu co hagati mu guhingura amavuta yo gusukura n’ivyo gukwiragiza.
Ivyuma vy’ubuhinga bwa none: Bikoreshwa nk’ikintu co gukura amazi mu mubiri mu gutegura ivyerekanwa vy’ubuhinga bwa none.
Analytical Chemistry: Ikora nk’igikoresho co gupima imiti kandi nk’igice kiri mu bikoresho vyo gushiramwo ibintu bishobora kuvangwa n’amazi.
Ibirango vy'ingenzi n'ivyiza
Ibikorwa bibiri: Itsinda rya acrylate rituma habaho copolymerisation, mu gihe umugwi wa hydroxyl ushobora gutuma habaho ugukorana n’ibindi binyabuzima hamwe n’uguhindura ibintu bitandukanye.
Ikora neza: Itanga ubushobozi budasanzwe bwo gukomera, guhangana n’imiti, no kwifatanya n’ibintu vy’iherezo.
Ivyiyumviro vyinshi: Bikorana bitagoranye n’ivyuma vy’amazi, ivyuma vy’amazi, styrène, ivyuma vy’amazi vy’amazi, ivyuma vy’amazi vy’amazi, n’ibindi.
Ugushobora gukoreshwa mu buryo bwinshi: Ibereye mu bikorwa bitandukanye vyo gukora ama polymérisation, harimwo n’ugukora polymérisation y’umuti, emulsion, n’ivyo gukora polymérisation y’amazi.
Ibikorwa vyiza: Bitanga iterambere rikomeye mu mico y’ibicuruzwa mbere no ku rwego rwo hasi rw’ugushiramwo (mu bisanzwe 2-10%).
Viscosity ntoyi: Ikora nk’ikintu gishobora gusubiza amazi mu bikoresho bishobora gukira n’imishwarara, bifasha kugabanya viscosity y’imiti ata gukoresha ibintu bishobora guhinduka (VOCs).
Gufata no kubika
Ubushuhe bwo kubika: Bibike ahantu hakanye kandi harimwo umwuka mwiza. Ubushuhe bwo kubika bubereye buri hagati ya 2°C na 25°C (36°F na 77°F). Irinde gukonja n’ubushuhe bwinshi.
Inhibiteur: Irimwo inhibiteur ya MEHQ kugira ngo ntihagire ivy’uguhinduka kw’ibihimba vy’umubiri bihinduka. Ico gikoresho co guhagarika gisaba ko haba umwuka w’ikirere kugira ngo gikore; rero, kubika munsi y’ikirere kitagira ico gikora (nk’akarorero, Nitrogen padding) ni ngombwa kugira ngo umuntu ashobore kugumaho igihe kirekire.
Igikoresho: Bibike mu bikoresho bipfutse neza bikozwe mu cuma kitagira ibara, mu cuma gifise ivyuma vy’ibara ry’agahama canke mu vyuma vy’ibara ry’agahama. Mukingire umuco.
Igihe co kubika: Mu bisanzwe amezi 6 gushika ku 12 kuva kw’igenekerezo ryakozweko iyo ibitswe mu buryo bubereye.
Uko ukoresha: Ukoreshe ufise umwuka uhagije be n’ubuhinga bwo kugenzura. Irinde gukorana n’urukoba, amaso n’impuzu. Ambara ibikoresho bikwiye vyo kwikingira (PPE), harimwo amaganzu adashobora guterwa n’imiti, amataratara yo kwikingira, n’impuzu zo kwikingira.
