Inzitizi-Yinshi ya Aluminium Foil kuri PU Foam Lamination & Thermal Insulation

1. Incamake y'ibicuruzwa

PU ifuro ya laminated aluminium foil numuhanga wabigize umwuga uhura nibikoresho bya polyurethane. Yakozwe mu bikoresho byibanze bya aluminiyumu bifite isuku irenze 99.4% binyuze mu nzira nyabagendwa ikonje ikonje, iyi fili ya ultra-thin aluminium igaragaramo ibintu byoroshye guhinduka, uburinganire bwuburinganire bumwe hamwe nuburyo bwizewe bwo guhuza ibikorwa. Iyo uhujwe cyane na PU ifuro ifatika kandi yoroheje, ikora nkibikorwa bibiri-birinda kandi byerekana ubushyuhe. Irashobora guhagarika neza imyuka yo mumazi yo hanze, umwuka hamwe nuwangiza, mugihe ishimangira imiterere ihamye hamwe nigihe kirekire cyogukoresha amashyuza ya PU ifuro. Ikoreshwa cyane mu kubungabunga ingufu, gukonjesha imbeho ikonje, gukora amamodoka n’inganda zo mu mazi zo mu mazi, ikemura ibibazo by’ububabare bw’ibanze harimo kwinjiza ibibyimba byinshi, kwiyongera k'ubushyuhe no gusaza mu mishinga isanzwe.

2. Ibyingenzi bya tekinike

3. Ibyiza byibicuruzwa

3.1 Kurinda inzitizi zose

Imiterere ya molekulari yuzuye ya aluminium foil itanga imikorere myinshi ya bariyeri ikora. Ihagarika burundu imyuka y’amazi yinjira mu mazi, ikarinda indwara y’imbere, gusenyuka kw'ifuro no kwangirika kw’ubushyuhe bwa PU ifuro, ikongerera igihe cyo gukora ibikoresho by’ibikoresho byangiza 30% kugeza kuri 50%. Hagati aho, itandukanya umwuka wa ogisijeni na gaze yangiza inganda kugirango igabanye gusaza kwa okiside. Byongeye kandi, irinda ifuro umukungugu, ibitonyanga-fatizo bya aside hamwe n’imyanda ihumanya, ihuza n’ibidukikije bikabije byo hanze.

3.2 Gutezimbere Ubushyuhe & Imiterere

Bitandukanye n’ubushyuhe bwa PU ifuro, ifu ya aluminiyumu yishingikiriza ku buso bwihariye kugira ngo igabanye ubushyuhe bukabije, ikora insimburangingo ebyiri zuzuzanya hamwe n’ifuro ya PU no guca ubushyuhe bw’inyubako 10% -15%. Nubuso bushimangira ubuso, butezimbere amarira hamwe nuburemere bukabije bwifuro ya PU yoroshye, irinda gushushanya hejuru no gutobora mugihe cyo gutwara, guteranya no kubaka aho. Irabuza kandi kwaguka kwinshi kwinshi no kugabanuka gukonje muri -40 ° C kugeza kuri + 80 ° C, bikagumya guhagarara neza kurwego rwo hejuru.

3.3 Gutunganya byoroshye & Inyungu Zigiciro

Ibicuruzwa byose bifata ibyemezo bifata O ubushyuhe bworoshye hamwe nubushakashatsi bwateguwe neza, bugera kumurongo uhoraho kandi uhoraho hamwe na PU ifuro ukoresheje lamination yumye, ibimera bitose hamwe nuburyo bwo kubira ifuro. Imiterere ya ultra-thin yoroheje irashobora guhuza ubuso bugoramye budasanzwe, imiyoboro ya pipine hamwe nu byuho byubatswe byubatswe nta fayili yamenetse. Bihujwe n’ibikorwa byingenzi byo gutembera mu nganda, gupfa no gukata ibikoresho, bigabanya uburyo bwo gutunganya ibice 20% -30%. Urupapuro rufite gusa munsi ya 5% yuburemere bwuzuye, bugumana inyungu yoroheje ya PU ifuro mugihe igenzura ibiciro byamasoko.

3.4 Ibidukikije-Byangiza & Kubungabunga Umutekano

Ubuvuzi bwose bwo hejuru bukoresha tekinoroji ya chromate idafite pasiporo, yujuje byimazeyo EU RoHS hamwe na REACH yubahiriza ibidukikije nta bisigazwa byibyuma biremereye. Aluminiyumu yinjizwamo imiti kandi ntishobora kubyara imiti cyangwa ibintu byangiza ubumara iyo uhuye nibikoresho fatizo bya PU. Iratsinda ibizamini byo mu rwego rutaziguye, bishobora gukoreshwa neza mububiko bukonje, gutwara ibiryo bishya hamwe no kuryama murugo.

4. Ibice byo hasi byerekanwa

4.1 Kubaka HVAC & Insulation

Ikoreshwa cyane kurukuta rwinyuma rukomeye rwa PU, izisenge zidafite amazi hamwe nudukingirizo two mu nzu. Kuri sisitemu ya HVAC, ikora nk'inyuma yo kureba imiyoboro y'umwuka, imiyoboro y'amazi ashyushye n'imbeho ikonje, itandukanya ubukonje no kugabanya ubushyuhe bw'imiyoboro. Ihujwe kandi na spray polyurethane ifuro ya atike hamwe na cavit yo munsi yo hasi kugirango birinde urukuta.

4.2 Urunigi rukonje & Inganda zikonjesha

Gukoreshwa muburyo bwimbere bwa firigo zo murugo hamwe na firigo yubucuruzi kugirango wirinde ubukonje no gukonjesha neza. Kububiko bunini bwubukonje, bwometse ku rukuta, hejuru no hasi ya plaque ya PU kugirango igabanye ubushyuhe buke bwo mu nzu no kugabanya ingufu za firigo. Muri firigo ikonjeshwa, ikoreshwa muburyo bwo kubika amakamyo akonjesha hamwe n’ibikoresho byoherezwa mu rwego rwo kurinda imbuto, imiti n’ibicuruzwa byafunzwe kugira ngo ubushyuhe bwangirika.

4.3 Ibikoresho byo murugo & Uburiri

Yashizwe kumurongo wa polyurethane yoroheje ya matelas na sofa yinyuma yinyuma, kubuza ubutaka gusubira inyuma no gutinda gukomera kwinshi no gusaza. Irakoreshwa kandi nk'urwego rushyigikira intebe y'ibiro hamwe n'ibikoresho byoroheje bipakira ibikoresho byo mu nzu, kunoza amajwi yo mu nzu no gukora neza bitarinze kugira ingaruka ku bikoresho byo mu nzu.

4.4 Ibinyabiziga, Marine & Gupakira Inganda

Mu gukora amamodoka, yongewemo na PU ifuro kumurongo wimodoka, imbaho ​​zumuryango imbere hamwe na disikuru yerekana amajwi kugirango bigabanye urusaku rwumuhanda no gutandukanya itandukaniro ryubushyuhe bwa kabine. Ku mishinga yo mu nyanja, irwanya umunyu wo ku nkombe kwangirika kwa kabine hamwe na hull. Mu gupakira inganda, ihuza PU ifuro yo kwisiga hamwe na bariyeri ya aluminium foil kugirango irinde ibikoresho bya elegitoroniki, ibirahure nibikoresho byoroshye mugihe cyo gutwara intera ndende.

5. Gahunda yumusaruro usanzwe

5.1 Gutegura Ibikoresho Byinshi Byuzuye

Hitamo ibyangombwa 99.4% + byibanze bya aluminiyumu yo gushonga no gukomeza guhora, utanga umubyimba wa aluminium 6-8mm. Igenzura ryinjira ryumwuga rikorwa kugirango hamenyekane ibishushanyo mbonera, okiside ya okiside hamwe n’ibikoresho bitandukanya imiti, bivanaho ibikoresho fatizo bitujuje ibyangombwa mbere yo kwinjira kumurongo.

5.2 Ibice byinshi bizunguruka & Annealing

Ubwa mbere, kuzunguruka bigabanya kugabanya umubyimba wa 2-3mm hagati ya aluminiyumu hagati yubushyuhe bwo hejuru. Noneho ubukonje bwinshi butambuka hejuru yubushyuhe bwicyumba buhoro buhoro kanda umurongo kugirango ugabanye uburebure bwa ultra-thin, byemeza ko kwihanganira umubyimba bigenzurwa muri ± 0.001mm. Hanyuma, inzogera ikomeza kuri 300-400 ° C ikuraho imihangayiko yimbere, igasubizaho aluminiyumu foil yoroheje ihindagurika nyuma.

5.3 Ubuvuzi bukora neza

Urupapuro rufata alkaline igabanuka kandi amazi ya deioniyo yogejwe kabiri kugirango akureho amavuta azunguruka hamwe n ivumbi ryo hejuru. Noneho chromate idafite passivation ikora firime ya nano-nini irinda okiside. Kubisabwa byabigenewe, 3-5μm acrylic cyangwa hot-melt yometseho yometseho ikoreshwa neza hamwe na roller, hanyuma hagakurikiraho ifuru yubushyuhe buke ikiza kuri 80-100 ° C kugirango ifungire hamwe.

5.4 Gutobora neza & Gukata impande zose

Emera servo iyobowe na mashini yihuta yo gutemagura kugirango ugabanye ibipapuro bigari mubugari bwihariye. Gukata ibyuma byikora bikuraho utubuto duto nu mpande zinyanja kugirango wirinde gutobora ifuro mugihe cyo kwihuta cyane. Imizingo yose yarangiye igenzurwa kugirango ubugari buringaniye mbere yo gupakira.

Niba ukeneye ibicuruzwa bya aluminium coil / urupapuro, nyamuneka twandikire kugirango tuganire byinshi.

Dingang Irangi rya aluminiyumu ni choie yawe nziza mugace kibyara umusaruro.

Dingang - Uruganda rukora umwuga kuri Aluminiyumu Alloy Amabara Yuzuye Coil ya Aluminium / Urupapuro Kuva 2002

Murakaza neza kugirango mutubaze niba hari icyo ukeneye kuri coating aluminium coil / urupapuro.

5.5 Byuzuye-Gutunganya QC & Ubushuhe-Bupfunyika

Igenzura ryanyuma ryibanze rikubiyemo ibintu bitanu byingenzi: gutahura uburebure bwa interineti, 180 ° ikizamini cyo gufatisha ibishishwa, kumenya inzitizi ya MVTR, gupima umunyu hamwe no gusikana pinhole. Ibicuruzwa byujuje ubuziranenge bipfunyikishijwe na firime ya PE-ibice bibiri, bigashyirwa ku mbaho ​​zometseho ibiti, kandi bikabikwa mu bubiko bw’ubushyuhe buri gihe hamwe n’ubushyuhe buri munsi ya 60% kugira ngo birinde okiside itose mu gihe cyo kubika no gutambuka.
