Cov kauj ruam rau kev casting polyurethane casters

Raws li peb txhua tus paub, polyurethane casters yog molded siv polyurethane raw khoom pouring. Pouring polyurethane casters yog ib tug txheej txheem uas muaj ntau qhov txuas, los ntawm kev npaj ua ntej mus rau qhov kawg kho thiab txij nkawm, txhua kauj ruam yuav tsum tau ua haujlwm meej thiab kev tswj hwm nruj. Yog li ntawd, muaj pes tsawg kauj ruam polyurethane roj hmab casters yuav tsum tau mus dhau los ua molded?

Kev npaj ua ntej
Ua ntej yuav pib nchuav cov polyurethane casters, yuav tsum tau npaj kom txaus. Ua ntej tshaj plaws, yuav tsum xaiv cov khoom siv raw xws li polyurethane resin, catalyst, filler thiab solvent. Cov ntaub ntawv no yuav tsum muaj lub zog zoo, tiv taus kev hnav thiab xeb. Tib lub sijhawm, yuav tsum npaj cov cuab yeej thiab cov khoom siv tsim nyog, xws li cov weighers, mixers, pwm thiab lwm yam. Kev xaiv pwm yuav tsum raws li qhov loj me thiab cov duab ntawm cov casters, thaum xyuas kom meej tias cov pwm ruaj khov thiab ruaj khov.
Sib tov
Sib tov cov polyurethane resin, catalyst, filler thiab solvent uas tau xaiv raws li qee qhov sib piv. Thaum lub sijhawm sib tov, xyuam xim rau kev tswj qhov kub thiab viscosity kom ntseeg tau tias cov khoom siv raw zoo. Tom qab sib tov, nchuav cov khoom polyurethane sib xyaw rau hauv pwm uas tau npaj ua ntej.
Ncuav
Thaum lub sijhawm nchuav, qhov ceev thiab lub siab yuav tsum tau tswj kom tsis txhob muaj teeb meem xws li cua npuas thiab tsis muaj khoom siv. Tib lub sijhawm, xyuam xim saib xyuas qhov xwm txheej nchuav thiab kho qhov ceev thiab lub siab ntawm kev nchuav raws sijhawm. Feem ntau, cov casting casters yuav tsum loj dua qhov loj me me uas xav tau rau kev txiav tom qab kho.
Kev Kho thiab Kev Txij Nkawm
Cov ntaub ntawv polyurethane yuav tsum tau kho thiab tswj xyuas tom qab casting. Lub sijhawm kho feem ntau yog 24 teev, thaum lub sijhawm ntawd qhov chaw ntawm cov slurry yuav tsum tau khaws cia noo noo, thiab tuaj yeem ua kom noo noo lossis tiv thaiv los ntawm lub hnub, thiab lwm yam, raws li cov xwm txheej kev tsim kho. Thaum lub sijhawm txij nkawm, yuav tsum tau ceev faj kom tsis txhob muaj kev cuam tshuam ntawm cov yam ntxwv sab nraud rau cov casters, xws li kub thiab av noo.
Cov yam ntxwv ntawm kev ua tau zoo
Kev tiv thaiv kev sib txhuam: cov log tsheb polyurethane muaj kev tiv thaiv kev sib txhuam siab heev, tuaj yeem siv tau ntev hauv qhov chaw ua haujlwm tsis zoo, thiab ua rau lub neej ua haujlwm ntev dua.

Ib lub polyurethane caster zoo yuav tsum muaj cov yam ntxwv hauv qab no:
Kev tsis kam roj: cov khoom siv muaj kev tiv thaiv corrosion zoo rau ntau hom roj thiab tsim nyog rau ntau qhov chaw muaj roj.
Kev tiv thaiv dej: cov log tsheb polyurethane tsis yooj yim rau deform hauv dej thiab muaj kev tiv thaiv dej zoo.
Kev tiv thaiv kub tsawg: cov khoom siv tseem tuaj yeem tswj tau qhov elasticity zoo nyob rau hauv qhov kub tsawg, tsim nyog rau thaj chaw txias.
Kev tiv thaiv ib puag ncig: cov khoom siv polyurethane tsis muaj tshuaj lom thiab tsis muaj ntxhiab, uas ua tau raws li qhov yuav tsum tau ua ntawm kev tiv thaiv ib puag ncig thiab yog qhov zoo rau kev txhim kho ruaj khov.
