Njira Zopangira Ma Polyurethane Casters

Monga tonse tikudziwa, ma polyurethane casters amapangidwa pogwiritsa ntchito kutsanulira zinthu zopangidwa ndi polyurethane. Kutsanulira ma polyurethane casters ndi njira yomwe imaphatikizapo maulalo ambiri, kuyambira kukonzekera koyambirira mpaka kukonza komaliza, gawo lililonse limafuna kugwira ntchito molondola komanso kuwongolera mosamala. Ndiye kodi ma polyurethane rabara casters amafunika kudutsamo masitepe angati kuti apangidwe?

Kukonzekera pasadakhale
Musanayambe kuthira ma polyurethane casters, pamafunika kukonzekera kokwanira. Choyamba, zinthu zoyenera monga polyurethane resin, catalyst, filler ndi solvent ziyenera kusankhidwa. Zipangizozi ziyenera kukhala ndi mphamvu yabwino yamakina, kukalamba komanso kukana dzimbiri. Nthawi yomweyo, zida ndi zida zoyenera ziyenera kukonzedwa, monga zoyezera, zosakaniza, ma mold ndi zina zotero. Kusankha ma mold kuyenera kutengera kukula ndi mawonekedwe a ma casters, pomwe kuonetsetsa kuti ma mold ndi olimba.
Kusakaniza
Sakanizani utomoni wa polyurethane, chothandizira, chodzaza ndi chosungunulira chomwe mwasankha molingana ndi kuchuluka kwake. Pakusakaniza, samalani ndi kuwongolera kutentha ndi kukhuthala kuti muwonetsetse kuti zinthu zopangira zili bwino. Mukasakaniza, tsanulirani zinthu zosakaniza za polyurethane mu nkhungu yokonzedwa kale.
Kuthira
Pa nthawi yothira, liwiro la kuthira ndi kupanikizika ziyenera kulamulidwa kuti zipewe mavuto monga thovu la mpweya ndi kusowa kwa zinthu. Nthawi yomweyo, samalani kuti muwone momwe kuthira kulili ndikusintha liwiro la kuthira ndi kukakamiza kwake pakapita nthawi. Kawirikawiri, ma casters othira ayenera kukhala akulu pang'ono kuposa kukula kwenikweni komwe kumafunika podulira pambuyo pothira.
Kukonza ndi Kukonza
Zipangizo za polyurethane ziyenera kutsukidwa ndi kusamalidwa pambuyo pozipaka. Nthawi yozipaka nthawi zambiri imakhala maola 24, ndipo nthawi imeneyi pamwamba pa matopewo payenera kukhala ponyowa, ndipo pakhoza kukhala chinyezi kapena kutetezedwa ku dzuwa, ndi zina zotero, malinga ndi momwe ntchito yomangira imakhalira. Panthawi yokonza, muyenera kusamala kuti mupewe kukhudzidwa ndi zinthu zakunja pa zinthu zopopera, monga kutentha ndi chinyezi.
Makhalidwe Ogwira Ntchito
Kukana kwa abrasion: Ma polyurethane casters opangidwa ndi cast ali ndi kukana kwakukulu kwa abrasion, angagwiritsidwe ntchito kwa nthawi yayitali m'malo osagwira ntchito bwino, ndikuwonjezera kwambiri moyo wautumiki.

Chotsukira cha polyurethane chabwino chiyenera kukhala ndi makhalidwe awa:
Kukana mafuta: chinthucho chili ndi kukana dzimbiri kwa mitundu yosiyanasiyana ya mafuta ndipo chimayenera kugwiritsidwa ntchito m'malo osiyanasiyana omwe ali ndi mafuta.
Kukana madzi: Ma polyurethane casters opangidwa ndi chitsulo samakhala osavuta kuonongeka m'madzi ndipo ali ndi kukana madzi bwino.
Kukana kutentha kochepa: zinthuzo zimatha kukhalabe zotanuka bwino ngakhale kutentha kutakhala kochepa, zoyenera malo ozizira.
Kuteteza chilengedwe: zinthu zopangidwa ndi polyurethane sizili ndi poizoni komanso sizinunkha, zomwe zimakwaniritsa zofunikira zoteteza chilengedwe ndipo zimathandiza kuti pakhale chitukuko chokhazikika.
