Izinyathelo zokufaka ama-polyurethane casters

Njengoba sonke sazi, ama-polyurethane casters abunjwa kusetshenziswa ukuthululwa kwezinto zokusetshenziswa kwe-polyurethane. Ukuthululwa kwama-polyurethane casters kuyinqubo ehilela izixhumanisi eziningi, kusukela ekulungisweni kokuqala kuya ekulungisweni kokugcina kanye nokugcinwa, isinyathelo ngasinye sidinga ukusebenza okunembile kanye nokulawula okuqinile. Ngakho-ke zingaki izinyathelo okudingeka zidlule kuma-polyurethane raber casters ukuze abunjwe?

Ukulungiselela kusengaphambili
Ngaphambi kokuqala ukuthulula ama-polyurethane casters, kudingeka ukulungiswa okwanele. Okokuqala, kufanele kukhethwe izinto zokusetshenziswa ezifanele njenge-polyurethane resin, i-catalyst, i-filler kanye ne-solvent. Lezi zinto kufanele zibe namandla amahle okusebenza, ukumelana nokuguguleka nokugqwala. Ngesikhathi esifanayo, kufanele kulungiswe amathuluzi nemishini efanele, njengezikali, abaxubi, ama-mold njalo njalo. Ukukhethwa kwama-mold kufanele kusekelwe kusayizi kanye nesimo sama-casters, kuyilapho kuqinisekiswa ukuqina nokuzinza kwama-mold.
Ukuxuba
Hlanganisa i-polyurethane resin ekhethiwe, i-catalyst, i-filler kanye ne-solvent ngokwesilinganiso esithile. Ngesikhathi senqubo yokuxuba, naka ukulawulwa kwezinga lokushisa kanye ne-viscosity ukuqinisekisa ukuthi ukugeleza kwezinto zokusetshenziswa kuhle. Ngemva kokuxuba, thela izinto ze-polyurethane ezixubile ku-mold elungiselelwe kusengaphambili.
Ukuthulula
Ngesikhathi senqubo yokuthulula, isivinini sokuthulula kanye nokucindezela kufanele kulawulwe ukuze kugwenywe izinkinga ezifana namabhamuza omoya kanye nokuntuleka kwezinto zokwakha. Ngesikhathi esifanayo, qaphela ukubheka isimo sokuthulula bese ulungisa isivinini sokuthulula kanye nokucindezela ngesikhathi. Ngokuvamile, ama-cast casters kufanele abe makhulu kancane kunosayizi wangempela odingekayo wokusika ngemva kokulungisa.
Ukwelapha Nokunakekela
Izinto ze-polyurethane zidinga ukupholiswa nokugcinwa zisesimweni esihle ngemva kokuphothwa. Isikhathi sokupholisa ngokuvamile singamahora angama-24, lapho ubuso be-slurry kufanele bugcinwe bumanzi, futhi bungafakwa umswakama noma buvikelwe elangeni, njll., ngokwezimo zokwakha. Ngesikhathi sokulungisa, kufanele kuqashelwe ukugwema ithonya lezinto zangaphandle kuma-casters, njengokushisa nomswakama.
Izici Zokusebenza
Ukumelana nokuguguleka: Ama-cast polyurethane casters anokumelana okukhulu kakhulu nokuguguleka, angasetshenziswa isikhathi eside endaweni yokusebenza embi, andisa kakhulu impilo yesevisi.

I-polyurethane caster enhle kufanele ibe nezici ezilandelayo:
Ukumelana nowoyela: le nto inokumelana okuhle nokugqwala ezinhlotsheni eziningi zamafutha futhi ifanelekela izindawo ezahlukahlukene ezingcoliswe uwoyela.
Ukumelana namanzi: ama-cast polyurethane casters akulula ukuwashintsha emanzini futhi anokumelana okuhle namanzi.
Ukumelana nokushisa okuphansi: izinto zokwakha zisengagcina ukuqina okuhle ngaphansi kwezimo zokushisa eziphansi, ezifanele izindawo ezibandayo.
Ukuvikelwa kwemvelo: izinto ze-polyurethane azinabo ubuthi futhi azinaphunga, ezihlangabezana nezidingo zokuvikelwa kwemvelo futhi zisiza ekuthuthukisweni okusimeme.
