Ubuyobozi bwa PU ni ubuhe?Ni izihe nyungu z'Inama y'Ubutegetsi ya PU?

2. Gukata neza ni muremure, kandi ikosa ryubunini ni ± 0.5mm, bityo ukemeza neza ubuso bwibicuruzwa byarangiye.

3. Ifuro ni nziza kandi selile zirasa.

4. Ubwinshi bwinshi ni bworoshye, bushobora kugabanya uburemere bwibicuruzwa byarangiye, biri munsi ya 30-60% ugereranije nibicuruzwa gakondo.

5. Imbaraga zo guhonyora cyane, zirashobora kwihanganira umuvuduko mwinshi mugikorwa cyo gukora ibicuruzwa byarangiye.

6. Nibyiza kugenzura neza.Kubera ko uruhu ruzengurutse rwakuweho mugihe cyo gutema, ubwiza bwikibaho burasobanutse iyo urebye, ibyo bikaba byerekana ingaruka ziterwa nubushyuhe bwibicuruzwa byarangiye.

7. Umubyimba urashobora kubyara no gutunganywa ukurikije ibyo abakoresha bakeneye.

Kugereranya imikorere yaikibaho cya polyurethanehamwe nibindi bikoresho byo kubika:

1. Inenge za polystirene: biroroshye gutwika mugihe habaye umuriro, bizagabanuka nyuma yigihe kinini, kandi bifite imikorere mibi yumuriro.

2. Inenge yubwoya bwamabuye hamwe nubwoya bwikirahure: kwangiza ibidukikije, kororoka kwa bagiteri, kwinjiza amazi menshi, ingaruka mbi ziterwa nubushyuhe bwumuriro, imbaraga nke, nubuzima bwigihe gito.

3. Inenge yibibaho bya fenolike: byoroshye okisijene, guhindura, kwinjiza amazi menshi, ubwinshi bworoshye kandi byoroshye kumeneka.

4. Ibyiza byububiko bwa polyurethane: flame retardant, ubushyuhe buke bwumuriro, ingaruka nziza yubushyuhe bwumuriro, kubika amajwi, urumuri kandi byoroshye kubaka.

Imikorere:

Imirima yaikibaho cya polyurethane:

Nkibikoresho byingenzi byibara ryibara rya sandwich, rikoreshwa cyane mumahugurwa yo kweza, mumahugurwa, ububiko bukonje, nibindi.
