Kodi PU magudumu? Pu gudumu ndi makhalidwe wotani?

PU gudumu kudziwika kusiyana a pulasitiki, mphira kasupe, wotchedwa: polyurethane kapena ma polima isocyanate. PU gudumu ndi mtanda pakati pulasitiki ndi mphira elastomer pakati ntchito zake zabwino akukhudzidwira ndi zachilendo wamba pulasitiki ndi mphira palibe.

　pu gudumu ndi makhalidwe wotani?

PU elastomer gudumu ndi kumva kuwawa, mankhwala kukana, mphamvu yapamwamba, elasticity mkulu, kukana kuti mochedwerako, kumva kuwawa, mayamwidwe mantha, kukana kuti womwetula, wabwino ntchito cheza kugonjetsedwa, mkulu katundu ndi mantha mayamwidwe gawo lotetezedwa ndi zina zotero. PU gudumu pamodzi ndi sikelo lonse kuuma kwa Shaw A10-100.

Pali kale kupitirira Shaw A100 ndi mankhwala zambiri. Komanso, PU gudumu ndi mantha aakulu mayamwidwe ntchito, mantha mayamwidwe cushioning timizere, zimakhudzira kugonjetsedwa kuposa zitsulo akasupe, kuti asawononge nkhungu. Izi zimaonetsa PU gudumu caster abwino kwambiri monga chuma.

Processing njira PU gudumu

PU elastomers akhoza kutenga gudumu ndi limodzi mastication mphira, kusakaniza, kuchiritsa ndondomeko akamaumba (amanena MPU); PU gudumu akhoza zopangidwa mphira madzi, anaponyedwa akamaumba kapena kupopera akuponya, centrifugal akamaumba (amatchula CPU); PU pellets kuzungulira akhoza kukhala ndi pulasitiki wamba, monga mwa jekeseni, extrusion, calendering, akamaumba nkhonya ndi njira zina (a CPU). Akamaumba kapena mbali jekeseni kuumbidwa kuti inde kuuma lonse, komanso amatha kudula, akupera, kuboola ndi Machining ena. Processing zosiyanasiyana, kuti applicability wa elastomers PU sizachilendo, wakhala kuwonjezera kuchuluka kwa ntchito.

　　Tsatanetsatane wa ntchito zipangizo PU gudumu Zofunika

PU caster gudumu zabwino kwambiri, zofewa thovu timizere Ololera PU chuma osati-monga mipando apamwamba, sofas, mphasa, polyurethane thovu ndi nkhambakamwa kwambiri mphasa zinthu zambiri, machila chuma ndi yofewa thovu yaikulu kuchuluka kwa ntchito gulu, amene ndi ansangala ndi wabwino.

Sound-kungolandira zipangizo-polyurethane thovu kutsegula ndi wabwino lamayimbidwe kugwedera absorber ntchito angagwiritsidwe ntchito ngati deta mkati phokoso bwino kuchepetsa phokoso la nyimbo chipinda;

zipangizo nsalu gulu-ziyangoyango phewa, kamisolo chinkhupule, thonje timizere; zidole.

Okhwima PU thovu PU

PU thovu gudumu mufuriji zipangizo-monga refrigerators, m'firiji, yosungirako ozizira, ozizira nyumba yosungiramo, etc., polyurethane thovu kutchinjiriza zipangizo zipangizo refrigeration ndi wosangalatsa kwambiri, kugwiritsa ntchito proportionate ambiri;
