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 vy'amazi y'amazi
HPA ikora kabiri bituma ikoreshwa mu bikorwa bitandukanye. Igikorwa caco nyamukuru ni ugukora nk’igikoresho co gusubiza amazi n’ugutanga ahantu h’uguhuza.
Ivyo gupfuka n'amarangi:
Ivyuma bitera ubushuhe: Bikora nk’ivyuma bifatanya n’ibindi bikoresho mu modoka, mu nganda no mu bikoresho vyo gupfuka ivyuma. Ifatanya n’ivyuma vyitwa melamine, isocyanate canke epoxy, ivyo bikaba bituma haba amafilime akomeye cane, adashobora guterwa n’imiti, adashobora gusenyuka kandi akayangana cane.
Ivyuma bishobora gukira n’imishwarara: Bikoreshwa mu bikoresho bishobora gukira n’imishwarara ya UV/EB, mu bipfukisho vy’amarangi no mu bifatanya. Itsinda ry’amazi ryitwa hydroxyl rituma hakorwa ivyuma vyitwa urethane acrylates bifise ubushobozi bwo gukora neza.
Ivyuma bishobora guhangana n’amashusho: Igikoresho nyamukuru mu bikoresho bishobora guhangana n’amashusho kugira ngo hakorwe ibikoresho bifata umuriro n’ibikoresho vyerekana.
Ivyo kwifatanya n'ivyo gukingira:
Itera imbere mu kwifatanya n’ibintu bigoye gufatanya nk’ivyuma n’amapulasitike yavuwe.
Itera imbere mu guhangana n’ubushuhe, guhangana n’imiti, no gukomera mu gufatanya mu bifatanya bishobora gushikirwa n’umukazo (PSAs) no mu bifatanya n’imibumbe.
Impuzu n'inyuguti:
Ikoreshwa nk’ikintu co gusukura intsinga kugira ngo ihindure intsinga zikozwe mu bihimba vy’umubiri, igatuma umuntu ashobora gutera ibara, akagira ubushobozi bwo gukingira ivyuma, kandi akagira ubushobozi bwo gufata ubukonje.
Ivyuma vy'ubuhinga n'amapulasitike:
Nk’umuhinduzi w’ivyuma vy’ivyuma n’ibindi bikoresho vy’ivyuma, Hydroxypropyl acrylate itanga ubushobozi bwo guhangana n’ibihe, ubushobozi bwo guhangana n’ibintu bikomeye, n’ubushobozi bwo guhinduranya.
Ibindi bikoresho:
Gutunganya impapuro: Nk’igice c’inkomezi c’ivyuma n’ivy’ugupfuka.
Imiti yo gusukura amazi: Ikoreshwa mu gukora imiti igabanya ububabare n’ubumara.
Ivyongera ku mavuta: Bikora nk’imbere y’ivyo gutuma index y’uburemere bw’amazi itera imbere n’ivyo gukwiragiza.
Ibirango vy'ingenzi n'ivyiza
Ivyiza cane: Itsinda ry’ivyuma vyitwa acrylate rishobora gukorana n’ivyuma vyinshi vy’ivyuma vy’ivyuma (nk’akarorero, methacrilate ya methyl, acrylate ya butyl, styrene, acrylonitrile).
Ubushobozi bukomeye bwo gukorana n’ibindi bihimba: Itsinda ry’amazi ryitwa pendant hydroxyl rikorana bitagoranye n’ibihimba vy’umubiri bita diisocyanates, anhydrides be n’ibihimba vy’umubiri bita amino (nk’akarorero, melamine), ivyo bikaba bituma habaho imirongo y’ibihimba vy’umubiri bikomeye kandi bifise ibipimo bitatu.
Ukwifatanya gukomeye: Gutuma habaho ugufatanya gukomeye n’ibintu bitandukanye.
Iterambere ry’Ugukomera: Bituma umuntu ashobora guhangana n’imiti, ibintu biyitera, ibihe be n’umuco w’izuba (UV).
Ubushobozi bwo gukora ibintu vyinshi: Bishobora gukoreshwa mu bikorwa vyinshi vy’ugukora ivyuma, harimwo n’ugutorera umuti, uguhindura ivyuma, uguhagarika, n’ugukora ivyuma vyinshi.
Ibikorwa vyiza: Bitanga iterambere rikomeye mu mico y’igicuruzwa ca nyuma mbere no ku rwego rwo hasi rw’ikoreshwa (mu bisanzwe 1-10%).
Gufata no kubika
Uko ubibika: Bibike ahantu hakanye, hari umwiza kandi harimwo umwuka mwiza. Gumana ibikoresho bipfutse neza. Ubushuhe bwo kubika bubereye buri hagati ya 15°C na 25°C (59°F na 77°F).
Inhibiteur: Irimwo MEHQ (Methoxyphenol) nk’inhibiteur y’uguhinduka kw’ibihimba vy’umubiri kugira ngo umuntu ntiyihindure ivy’umubiri mu gihe co kubika no gutwara. Ni ngombwa cane ko iyo inhibiteur igumaho kugira ngo igumye.
Uko wovyifatamwo: Niwirinde gukorana n’ubushuhe, ibishashi, imbeya zifunguye be n’ibintu bikomeye bitera umwuka. Koresha n’umwuka uhagije kandi wambare ibikoresho bikwiye vyo kwikingira (PPE), harimwo n’amaganzu adashobora guterwa n’imiti, amataratara y’umutekano be n’impuzu zo kwikingira.
Igihe co kubika: Mu bisanzwe amezi 12 kuva kw’igenekerezo ryakozweko iyo ibitswe mu buryo bubereye.
