Nka polyurethane rigid ifuro (PU rigid foam) ifite ibiranga uburemere bwurumuri, ingaruka nziza yo gutwika amashyuza, kubaka byoroshye, nibindi, kandi ikagira kandi ibintu byiza cyane nko kubika amajwi, kurwanya ihungabana, kubika amashanyarazi, kurwanya ubushyuhe, kurwanya ubukonje, solvent kurwanya, nibindi, byakoreshejwe cyane murugo no mumahanga.Mu kirere, kubaka ubwato, peteroli, ibikoresho bya elegitoronike, ibinyabiziga, ibiribwa n’izindi nzego.
Imikoreshereze nyamukuru ya PU igoye ifuro niyi ikurikira:
1. Ibikoresho byo gukonjesha ibikoresho byo murugo ninganda zibiribwa
Firigona firigo ikoresha PU igoye ifuro nkurwego rwo kubika ibintu bifite urwego ruto cyane.Mubipimo bimwe byo hanze, ingano yingirakamaro nini cyane kuruta mugihe ibindi bikoresho bikoreshwa nkurwego rwo kubika, kandi uburemere bwibikoresho nabwo buragabanuka.
Amashanyarazi yo murugo urugo, ubushyuhe bwamazi yizuba, hamwe ninzoga ya keg muri rusange bakoresha ibikoresho bikomeye bya polyurethane.PU ikomeye ifuro nayo ikoreshwa mugukora incubator zigendanwa zo gutwara ibicuruzwa, imiti nibiribwa bisaba kubika ubushyuhe no kubibungabunga.
2.Ibikoresho byo mu nganda kandiumuyoborokwigana
Ibigega byo kubika naimiyoborozikoreshwa cyane mubikoresho byinganda, kandi zikoreshwa cyane muri peteroli, gaze gasanzwe, gutunganya peteroli, inganda zimiti, inganda zoroheje nizindi nganda.Imiterere yikigega cyo kubikamo ni serefegitire cyangwa silindrike, kandi PU ikomeye ifuro irashobora kubakwa mugutera, gusuka no gushiramo ifuro ryakozwe mbere.Nka aumuyoboroibikoresho byo kubika amashyuza, bikoreshwa cyane mugukwirakwiza ubushyuhe bwimiyoboro mu gutwara peteroliimiyoboron'inganda za peteroli, kandi yasimbuye neza ibikoresho byo kwinjiza amazi menshi nka perlite.
3. Ibikoresho byo kubaka
Kubaka amazu nimwe murwego rwingenzi rwo gukoresha PU rukomeye.Mu Bushinwa, ifuro rikaze ryamamaye cyane mu gukumira ubushyuhe no kwirinda amazi hejuru y’inzu y’amazu yo guturamo n’ibiro,kubaka ibikoresho, hamwe nibikoresho byo kubika ubushyuhe bwaicyumba gikonjeububiko bwimbuto, nibindi.
Rigid polyurethanesandwichzikoreshwa cyane mu nganda zinganda, mububiko, stade, amazu yabaturage, villa, amazu ya prefab hamweicyumba gikonje, nkibisenge byamazu hamwe nimbaho.Kubera uburemere bwacyo bworoshye, kubika ubushyuhe, kutagira amazi, gushushanya nibindi biranga, hamwe no gutwara ibintu byoroshye (kwishyiriraho), iterambere ryihuse, birakunzwe cyane mubashushanya, ubwubatsi nabateza imbere.
4.Ibikoresho byo kwigana ibiti
Ubucucike bwinshi (ubucucike 300 ~ 700kg / m3) PU ikomeye ifuro cyangwa ibirahuri fibre ikomezwa cyane ifuro ni plastiki yububiko, izwi kandi nkaibiti.Irashobora gusimbuza ibiti nkibisobanuro bitandukanye byo mu rwego rwo hejuru, imbaho, ibicuruzwa bya siporo, ibikoresho byo gushushanya,urugoibikoresho,indorerwamo,umutego,igitanda ,prothèse,upholster,kumurika ibikoresho, nakwigana ibiti byubukorikori, etc.
Kubumba ikamban'imirongo ya pompe ni imirongo yo gushushanya imbere, ariko ibikoresho byo gukora nubwubatsi biratandukanye.Imirongo ya PU ikozwe muri PU ibikoresho fatizo.Ikorwa numuvuduko ukabije wifuro ya polymer ifuro, kandi ikozwe na pu ifuro ikomeye.Iyi pu ifata ifu ivanze nibice bibiri kumuvuduko mwinshi mumashini ya parufe, hanyuma ikinjira mubibumbano kugirango ikore.Icyorezo gikomeye.Ntabwo ari uburozi kandi butagira ingaruka, byangiza ibidukikije cyane.
Ibishushanyontabwo zahinduwe, zacitse, cyangwa ziboze;Kurwanya ruswa, aside na alkali birwanya, kandi birashobora kugumana ituze ryibintu umwaka wose.Nta kurya inyenzi, nta terite;nta kwinjiza amazi, nta nyanja, birashobora gukaraba neza.Ubushyuhe bukabije bwumuriro, nigicuruzwa cyiza cyane cyo kubika ubushyuhe, ntabwo kizatanga ibiraro bikonje nubushyuhe.
Imyendamannequinsni shyashya ikoreshwa murwego rwa polyurethane.Icyitegererezoni kimwe mubintu byingenzi mububiko bwimyenda.Barashobora kwambara iduka no kwerekana ibintu byingenzi biranga imyenda.Imyenda isanzwe iri kumasoko ikozwe muri fibre fibre, plastike nibindi bikoresho.Fiberglass fibre ifite imyambarire idahwitse yo kwambara, irasa naho yoroheje, kandi nta elastique ifite.Plastike ifite inenge nkimbaraga nke nubuzima bugufi.Imyenda ya polyurethane ifite ibyiza byo kurwanya kwambara neza, imbaraga nziza, elastique, imikorere myiza yo kwisiga, hamwe nurwego rwo hejuru rwo kwigana.
7.Ibindi bikorwa bisanzwe
Usibye porogaramu zavuzwe haruguru, polyurethane ikomeye ifuro irashobora no gukoreshwa mukuzuza inzugi no kubyara imipira ireremba, nibindi.
Urugi rwuzuye polyurethane rwuzuye rusa nkurindi rugi, nyamara, imiterere yimbere iratandukanye rwose.Mubisanzwe urugi rutagira irangi ruba rwuzuye imbere, cyangwa rwuzuyemo impapuro zubuki, mugihe urugi rwa polyurethane rukomeye rwuzuye ifuro ntabwo ari icyatsi gusa kandi cyangiza ibidukikije gusa, ahubwo runashimangira ubukana bwikariso yumuryango, bigatuma urugi rukomera kandi rukomeye. , niba ari ibintu biremereye cyane, amazi menshi, Yaba yatwitse mumuriro, irashobora kwemeza ko itazigera ihinduka.Iri koranabuhanga rikuraho inzugi zifatanije, Inzugi zimbaho zikunze guhura nibibazo nko guhindagurika nubushuhe.
