Ibibazo bisanzwe mubikorwa byo kubyaraPU yigana ibitini:1. Epidermal bubbles:Ibicuruzwa byubu birahari rwose, ariko hariho ibibazo bike.2. Umurongo wera w'icyorezo:Ikibazo mubihe byubu umusaruro nuburyo bwo kugabanya umurongo wera no gusana aho umurongo wera ugaragara.3. Gukomera k'uruhu:Ukurikije ibisabwa bitandukanye byabakiriya, kuri ubu nta bipimo nyabyo bihari.Isesengura ryibibazo byavuzwe haruguru nuburyo bukurikira: 1. Epidermal bubbles:Ukurikije ahantu hamwe na phenomenon, ibitera biratandukanye.Impamvu zisanzwe ni:(1) Ibibazo byimbunda ifuro:a.Byakozwe mugihe cyo kuvanga: gerageza kugabanya ibibyimba biva mugihe ibintu byinshi bibyimba biva mumutwe wimbunda, nko kuvanga nabi no guhumeka ikirere kumutwe wimbunda.b.Kuvanga umuvuduko (kumashini yumuvuduko muke): umuvuduko mwinshi, nibyiza, kandi bito bitemba, nibyiza.c.Ntutere umurizo kubicuruzwa.d.Ubushyuhe bwibintu buri hejuru, reaction irihuta, kandi ibibyimba bizagabanuka (cyane cyane mugihe cy'itumba).e.Umubare wibikoresho byirabura ni mwinshi, umwuka mwinshi uriyongera, kandi igitutu cyikigega gikomeza kuba gihamye.f.Umwanda n'umukungugu bivanze mumutwe wimbunda ifuro.(2) Ingaruka zububiko:a.Ubushyuhe bwububiko buri hejuru, ibituba bizagabanuka.b.Ingaruka yumubyimba, impande zifatika zifatika.c.Imiterere yububiko igena ko ibicuruzwa bimwe ari byinshi, nibicuruzwa bimwe bikaba bike.d.Ubuso bwububiko bworoshye nubuso bwububiko.(3) Kugenzura inzira:a.Ingaruka zo gukaraba no kudahanagura, gutera inshinge nyinshi.b.Gufunga ibicuruzwa bitinze bizagabanya umwuka mubi.c.Inzira yo gutera inshinge no gukwirakwiza ibikoresho bibisi imbere.(4) Ingaruka z'umukozi wo kurekura:a.Ibikoresho byo gusohora amavuta ya Silicone bifite ibibyimba byinshi kandi bitagira ibishashara2. Ikibazo cyumurongo wera wibicuruzwa epidermis:Iyo ibikoresho bibisi byinjijwe mubibumbano, hazabaho itandukaniro ryigihe, bityo hazabaho itandukaniro ryigihe mugihe ibikoresho bibisi bitangiye kubyitwaramo, kuburyo imirongo yera izabyara igice cyuzuyemo intera mbere na nyuma ya reaction.Impamvu nyamukuru zibitera ni: Ikibazo gikomeye:a.Iyo ubushyuhe bwibumba ari 40-50 ℃, umurongo wera uzagabanuka.b.Inguni ihindagurika yububiko iratandukanye, kandi umwanya wumurongo wera nawo uratandukanye.c.Ubushyuhe bwaho bwubushyuhe bwubushyuhe buri hejuru cyane, bivamo ibihe bitandukanye byo gufata ibikoresho bibisi, bivamo imirongo yera.d.Niba ibicuruzwa ari binini cyane cyangwa binini cyane, umurongo wera uziyongera.e.Ifumbire ni igice cyamazi yanduye kandi umukozi wo kurekura ntabwo yumye, bivamo imirongo yera.Gun Imbunda ifata ifuro:a.Ubushyuhe bwo hejuru bwibikoresho bizagabanya umurongo wera, kandi ahantu umurongo wera ugaragara mugihe igipimo cyibintu byirabura ari kinini birakomeye.b.(Imashini yumuvuduko muke) Umuvuduko mwinshi wumutwe wimbunda, ingaruka zo kuvanga nibyiza, kandi umurongo wera uzagabanuka.c.Hazaba imirongo yera kumutwe no murizo wibikoresho.(3) Kugenzura inzira:a.Ubwiyongere bwumubare wibikoresho fatizo bizagabanya umurongo wera.b.Nyuma yo gutera inshinge, koza bizagabanya imirongo yera.3. Gukomera kw'ibicuruzwa:a.Ubucucike bwibikoresho fatizo ni byinshi, ubukana bwibicuruzwa buriyongera, ariko ubwinshi bwo kwinjiza bwiyongera.b.Umubare wibikoresho byirabura ni mwinshi.Icyorezo cya Epidermal kiriyongera.c.Iyo ubushyuhe bwubushyuhe nubushyuhe bwibintu biri hejuru, ubukana bwibicuruzwa buzagabanuka.d.Umukozi wo kurekura azagabanya ubukana bwuruhu, kandi irangi-mubumba bizongera ubukana bwuruhu.Ibicuruzwa byujuje ibyangombwa bigomba kugenzurwa mubijyanye nibikoresho, ibikoresho fatizo, inzira, ibishushanyo, nibindi, bityo rero birasabwa gushaka ubufatanye nabatanga ibikoresho bya polyurethane mugikorwa cyo gukora.
