Njengoko sonke sisazi, ii-polyurethane casters zibunjwa kusetyenziswa izinto eziluhlaza ze-polyurethane. Ukugalela ii-polyurethane casters yinkqubo ebandakanya amakhonkco amaninzi, ukusuka ekulungiseleleni kwangaphambili ukuya ekucocweni kokugqibela kunye nokugcinwa, inyathelo ngalinye lifuna ukusebenza ngokuchanekileyo kunye nolawulo olungqongqo. Ngoko ke kufuneka zidlule amanyathelo amangaphi ii-polyurethane rubber casters ukuze zibunjwe?
Ukulungiselela kwangaphambili
Ngaphambi kokuba uqale ukuthulula ii-polyurethane casters, kufuneka kulungiselelwe ngokwaneleyo. Okokuqala, kufuneka kukhethwe izinto ezifanelekileyo ezifana ne-polyurethane resin, i-catalyst, i-filler kunye ne-solvent. Ezi zinto kufuneka zibe namandla afanelekileyo oomatshini, ukuguguleka kunye nokumelana nokugqwala. Kwangaxeshanye, kufuneka kulungiswe izixhobo ezifanelekileyo kunye nezixhobo, ezifana nezikali, abaxubi, ii-molds njalo njalo. Ukukhethwa kwee-molds kufuneka kusekelwe kubukhulu kunye nokuma kwee-casters, ngelixa kuqinisekiswa ukuqina kunye nokuzinza kwee-molds.
Ukuxuba
Xuba i-polyurethane resin ekhethiweyo, i-catalyst, i-filler kunye ne-solvent ngokwemilinganiselo ethile. Ngexesha lenkqubo yokuxuba, qwalasela ulawulo lobushushu kunye ne-viscosity ukuqinisekisa ukuba ukunyibilika kwezinto ezikrwada kulungile. Emva kokuxuba, galela izinto ezixutyiweyo ze-polyurethane kwi-mold elungiselelwe kwangaphambili.
Ukuthulula
Ngexesha lenkqubo yokugalela, isantya sokugalela kunye noxinzelelo kufuneka kulawulwe ukuze kuthintelwe iingxaki ezifana namaqamza omoya kunye nokungabikho kwezinto. Kwangaxeshanye, qaphela imeko yokugalela kwaye ulungise isantya sokugalela kunye noxinzelelo ngexesha. Ngokubanzi, ii-casters zokugalela kufuneka zibe nkulu kancinci kunobungakanani obufunekayo bokucheba emva kokucola.
Ukulungisa kunye nokulungisa
Izinto zepolyurethane kufuneka zilungiswe kwaye zigcinwe emva kokuphoswa. Ixesha lokuphola ngokubanzi liziiyure ezingama-24, apho umphezulu we-slurry kufuneka ugcinwe umanzi, kwaye unokufunyiswa okanye ukhuselwe elangeni, njl.njl., ngokweemeko zokwakha. Ngexesha lokugcinwa, kufuneka kuthathwe unonophelo ukuze kuthintelwe impembelelo yezinto zangaphandle kwi-casters, ezifana nobushushu kunye nokufuma.
Iimpawu zokusebenza
Ukumelana nokukrala: ii-cast polyurethane casters zinokumelana nokukrala okuphezulu kakhulu, zingasetyenziswa ixesha elide kwindawo yokusebenza embi, zandisa kakhulu ubomi benkonzo.
I-polyurethane caster elungileyo kufuneka ibe neempawu ezilandelayo:
Ukumelana neoyile: le nto inokumelana nokugqwala kwiintlobo ngeentlobo zeeoyile kwaye ifanelekile kwiindawo ezahlukeneyo ezingcoliswe yioyile.
Ukumelana namanzi: ii-cast polyurethane casters azilula ukuziguqula emanzini kwaye zinokumelana namanzi kakuhle.
Ukumelana nobushushu obuphantsi: izinto zisenokuqina kakuhle phantsi kweemeko zobushushu obuphantsi, zifanelekile kwiindawo ezibandayo.
Ukhuseleko lokusingqongileyo: izinto ze-polyurethane azinatyhefu kwaye azinavumba, nto leyo ehlangabezana neemfuno zokhuseleko lokusingqongileyo kwaye ikhuthaza uphuhliso oluzinzileyo.
