Parike ya Polyurethane: Igisubizo cy'iparike ihamye kandi irambye

Mu bwubatsi bwa none, imitako yo hasi si igice cy’ubwiza gusa, ahubwo inanuzuza ibisabwa by’ingenzi. Nk’ubwoko bushya bw’ibikoresho byo gushariza hasi, imitako ya polyurethane ifite imikorere myiza kandi ikoreshwa mu buryo butandukanye.

Iyi nkuru izakwereka imiterere, ibyiza n'imiterere ikoreshwa mu gupfunyika hasi hakoreshejwe polyurethane.
Mbere na mbere, hasi ha polyurethane haramba kandi rirakomeye. Ikoresha resin ya polyurethane nk'ibikoresho by'ibanze kandi ikorwa binyuze mu buryo bwihariye. Hasi ya polyurethane ifite ubushobozi bwo kudashira no kwangirika kw'imiti. Ishobora kurwanya kwangirika kw'ibintu byo hanze nka peteroli, aside na alkali, kandi igakomeza ubwiza bw'ubutaka igihe kirekire.

Muri icyo gihe, hasi hakozwe na polyurethane hafite ubushobozi bwo kudakoresha umuvuduko mwinshi kandi hadasaza, hashobora kwihanganira gukoreshwa cyane, hadakunze kwangirika cyangwa kwangirika, kandi bikongera igihe cyo kubaho kw'ubutaka.

Icya kabiri, hasi ha polyurethane hari imiterere myiza yo kwirinda kunyerera no kurinda umutekano. Ubuso bw'ubutaka bwa polyurethane bukoresha uburyo bwihariye bwo kwirinda kunyerera, bushobora gutanga uburyo bwiza bwo gukururana no kugabanya ibyago byo kunyerera iyo abantu bagenda. Ibi bituma hasi ha polyurethane hakoreshwa cyane ahantu hasaba kwirinda kunyerera, nko mu nganda, mu magorofa y'ibitaro, mu ngo, n'ahandi.

Byongeye kandi, hasi ya polyurethane ifite imiterere idahumanya ibidukikije. Ikoresha formula idafite solvent, nta bintu byangiza birimo, kandi nta mwanda cyangwa ngo igire ingaruka ku mubiri w'umuntu no ku bidukikije. Mu gihe cyo kuyikoresha, hasi ya polyurethane ntabwo izatanga imyuka mibi nka formaldehyde, ikarinda neza ubwiza bw'umwuka wo mu nzu kandi igahura n'ibisabwa mu kurengera ibidukikije mu nyubako zigezweho. Ku bikenewe bitandukanye mu nyubako, hasi ya polyurethane ishobora guhindurwa hakurikijwe imiterere nyayo. Ishobora guhitamo amabara atandukanye n'imiterere kugira ngo ihuze n'ibisabwa mu mitako yihariye.

Kubaka hasi ya polyurethane biroroshye kandi byihuse, kandi ntibisaba kwitabwaho no kubungabungwa igihe kirekire, ibyo bikaba bigabanya cyane igihe n'ikiguzi. Muri make, hasi ya polyurethane yabaye amahitamo meza yo gushariza hasi mu nyubako zigezweho bitewe n'uko iramba neza, umutekano wayo udacika ndetse n'imikorere yayo idahungabanya ibidukikije. Byaba ari uruganda, ibitaro, sitade cyangwa ahantu h'ubucuruzi, hasi ya polyurethane ishobora kuguha ibisubizo byiza, bifatika kandi birambye.
