Ibikorwa Gukora no Kugura Ubuhanga bwa Polyurethane Imashini Yinshi kandi Ntoya Yumuvuduko

Imashini ifata polyurethane ni ibikoresho bidasanzwe byo gushiramo no kubira ifuro rya polyurethane.Igihe cyose ibipimo bya polyurethane ibikoresho fatizo (ibice bya isocyanate hamwe na polyether polyol) ibipimo byerekana imikorere yujuje ibisabwa.Ibicuruzwa byinshi kandi byujuje ibyangombwa birashobora gukorwa binyuze mumashini ya polyurethane yo hejuru kandi ntoya.Ikozwe muri plastiki ifuro hamwe na chimique reaction ya polyether polyol na polyisocyanate imbere yinyongeramusaruro zitandukanye nka agent ifuro ifuro, catalizator na emulifier.

Kwirinda imikorere yaimashini ya polyurethane
1. Theimashini ya polyurethaneugomba kwambara ibirahure birinda, imyenda yakazi hamwe na capit yakazi, hamwe na gants ya reberi mugihe ukoresha ibikoresho bya polyurethane A na B.Ibidukikije bikora bigomba guhumeka neza kandi bifite isuku.Iyo ubushyuhe bwibidukikije buri hejuru, umukozi wifuro muri polyurethane Ikintu kizahinduka igice kandi kibyara umuvuduko, bityo igifuniko cyuka kigomba gukingurwa mbere kugirango kirekure gaze, hanyuma hagomba gufungurwa igifuniko.
2. Iyo imashini ya polyurethane ifuro ifite ibyangombwa bisubiza inyuma ifuro, imashini ifata polyurethane irashobora gukoresha flame retardant.Ingano yinyongera ya flame retardant isanzwe ni 15-20% yuburemere bwibintu byera, kandi flame retardant yongewe kuri polyurethane A.Igomba gukangurwa neza mbere yo kubira ifuro.
3. Mugihe cyimikorere yintoki yimashini ya polyurethane ifata ifuro, bapima neza ibikoresho bya polyurethane A na B bikwiranye hanyuma ubisuke muri kontineri icyarimwe.Nyuma yo gukurura amasegonda 8 kugeza 10 hamwe na stirrer irenga 2000 rpm, suka mubibumbano na furo.Igihe cyo kumanura biterwa nibicuruzwa bisabwa, ubunini bwa furo, nibindi.
4. Iyo uruhu ruhuye nibintu bya polyurethane bihujwe A, bigomba gukaraba n'isabune n'amazi.Iyo imashini ifata polyurethane ikora ibikoresho bya polyurethane B (hariho uburakari runaka), ntugahumeke umwuka wacyo kandi ntukabijugunye kuruhu n'amaso.Iyo bigeze ku ruhu n'amaso, bigomba guhita bihanagurwa n'ipamba yo kwa muganga, hanyuma bigakaraba n'amazi menshi muminota 15, hanyuma bigakaraba isabune cyangwa inzoga.

Kugura ubuhanga bwimashini ya polyurethane
1. Sobanukirwa neza ubwoko bwimashini ifuro
Ihame ryibanze ryimashini ifata polyurethane nugushira gaze mumuti wamazi wumuti wifuro, ariko ubwoko butandukanye bwimashini zifuro zitangiza gaze muburyo butandukanye.Kurugero, umuvuduko muke wo gukurura wishingikiriza kumashanyarazi yihuta yihuta kugirango azane gaze, bikavamo ibisohoka bito bito kandi bikora neza;ubwoko bwihuta bwihuta bushingira kumuvuduko mwinshi uzunguruka umuyaga uva amaraso, ubunini bwibibyimba ntibushobora kugenzurwa, kandi ifuro ntiringana;umuvuduko mwinshi hamwe nubwoko buciriritse bwubwoko butanga ifuro Umuvuduko mwinshi, gukora neza, umwe hamwe nuduto duto.
2. Ibipimo fatizo byimashini ifata polyurethane:
1) Umusaruro: Umusaruro ni ingano ya furo yakozwe, igomba kuba hejuru gato ugereranije n’ifuro isabwa na 20%.Kugirango uve mucyumba ingano y’ifuro yakozwe, imipaka yo hasi igomba gukoreshwa nkishingiro ryo kubara no kubara, kandi imipaka yo hejuru ntishobora gukoreshwa.
2) Ubushobozi bwashyizweho bwa mashini ya polyurethane ifuro: ubushobozi bwashyizweho nimbaraga zose zashyizweho.Iyi parameter ifite akamaro kanini mukubara guhuza imiyoboro yumuriro wamashanyarazi.
3) Ingano na diameter ya mashini ya polyurethane.
