Rigid PU Ikomatanyirizo ryubuyobozi
Ibisobanuro ku bicuruzwa
Ikibaho gikomeye cya polyurethane gikomatanya ikibaho ni ikibaho cyiziritse gifite ibikoresho bya insimburangingo ya polyurethane nkibikoresho byibanze hamwe na sima ishingiye ku kurinda impande zombi.Ifata ibikoresho bikomeza kubyaza umusaruro-icyiciro cya kabiri, kitujuje gusa ibipimo bihanitse byo kubaka izigama ingufu, ariko kandi bikazamura ituze rya sisitemu;ikibaho gifite intera ebyiri mugihe kiva muruganda, gishobora kwirinda neza umuriro uterwa nigituba cy itabi hamwe nogusudira amashanyarazi mugihe cyo gutwara, kubaka ahubatswe no kubaka urukuta;polyurethane ikomeye cyane ni ibikoresho bya termosetting kandi ntibishobora guhura numuriro.Gushonga, nta bitonyanga byaka, nta gukwirakwiza umuriro nyuma yo gukora sisitemu, kuzamura cyane kurwanya umuriro mugihe cyo gukoresha.Ubuso bubiri bwa sima bushingiye kubutaka bushobora kongera imbaraga zo guhuza ikibaho cyiziritse, ibifata hamwe na pompe ya pompe, bityo bigatuma uburinganire n'ubwuzuzanye bwa sisitemu.

Icyiciro cyibicuruzwa
01 |Amashanyarazi
Ifuro ya polyurethane ya Rigid ifite imiterere ihuza cyane, ifunze-selile (igipimo cyo gufungura 5%), hamwe nubushyuhe buke cyane, 0.021W / (mK).
02 |Ubukungu
Ifite igihe kirekire cyo gukoresha nigihe cyiza cyo gukora ubushyuhe.Umubyimba wacyo uroroshye 2/3 kurenza ubushyuhe bwumuriro na 1/3 cyoroshye kurenza ikibaho cya polystirene.Igikorwa cyuzuye cyibiciro kuri buri kare kare ni nziza.
03 | gushikama
Polyurethane ikomeye cyane ifata cyane cyane ya halogene idafite flame-retardant polyether polyol, ikongeramo fosifore ishingiye kuri flame retardant hamwe ningaruka zo guhuza imbaraga kugirango igere kumiterere ya halogene idafite flame-retardant muri molekile ya furo itongera ubwinshi bwa isocyanate.Imikorere ya flame-retardant igeze kuri B1 bisanzwe;sisitemu ya polyurethane yo hanze yububiko bwatsinze imishinga myinshi hamwe na sisitemu nyinshi, kandi ntihazabaho ikibazo cyibikoresho byo kubika bigwa nyuma yo gusaba injeniyeri.
04 | Kurengera ibidukikije
Kwemeza tekinoroji ya florine idafite ibicuruzwa nibicuruzwa bitarimo aldehyde, ni ibikoresho byubaka icyatsi.
05 | Kuramba
Ifite imiti irwanya imiti kandi irashobora gukoreshwa igihe kirekire ku bushyuhe bwa -180 ° C ~ 150C.Ifite ibihe byiza byo guhangana nikirere no kurwanya ubukonje kandi irashobora gukoreshwa mugihe cyimyaka 50.
06 | Ubwubatsi
Inzira yo kubaka iroroshye, itekanye kandi yizewe, kandi inzira zitandukanye zo kubaka zirashobora gutoranywa kubikorwa bitandukanye.
