Nkawm khau factories sivpolyurethane raw kua rau khau khauFeem ntau ntsib cov teeb meem paub: npuas, shrinkage, tsis sib xws, tsis zoo demolding, nto pinholes, los yog tsis ruaj khov hardness. Cov teeb meem no ua rau cov khoom seem, ncua kev xa khoom, thiab ua rau muaj kev tsis sib haum xeeb nrog cov hom. Cov xov xwm zoo: feem ntau tsis xws luag yog tiv thaiv tau thaum lubPU ib leeg systemyog matched kom raug thiab ntau lawm tsis yog tswj.
Tsab ntawv xov xwm no qhia txog cov ntsiab lus mob uas tau tshawb nrhiav ntau tshaj plaws rauPU txhaj tshuaj ib leeg khoomthiab muab cov lus qhia siv tau los pab cov neeg yuav khoom ntsuas tus neeg muag khoom lub peev xwm.
Teeb meem 1: npuas / Pinholes hauv PU Soles
Kev tshawb nrhiav hauv Google:
PU npuas npuas, polyurethane ib leeg pinholes, PU txhaj tshuaj cua npuas, Yuav ua li cas tshem tawm npuas hauv PU casting.
Tej yam ua rau:
Moisture nyob rau hauv raw cov ntaub ntawv, fillers, los yog pigments
Nqus plua plav degassing (rau casting)
Kev sib xyaw ua ke tsis raug lossis sib xyaw cov teeb meem
Qhov kub tsis sib haum ua rau muaj roj gas
Inconsistent feem ratio
Cov kev daws teeb meem:
Khaws cov ntaub ntawv kaw; tswj cov av noo nyob rau hauv cia
Xyuas kom cov tank thiab cov kav dej qhuav thiab huv si
Siv cov kev pom zoo sib xyaw ua ke thiab ruaj khov tshuab siab
Xaiv lub kaw lus uas tsim nyog viscosity thiab ntws rau koj cov pwm tsim
Tus neeg muag khoom muaj zog yuav tsum muab cov kev txwv tsis pub ya raws pom zoo thiab cov kauj ruam daws teeb meem.
Teeb meem 2: Shrinkage / Warping / Deformation
Cov ntsiab lus tshawb nrhiav:
PU ib leeg shrinkage, polyurethane ib leeg warping, PU ib leeg deformation tom qab demould.
Tej yam ua rau:
Lub sijhawm demold ceev heev
Pwm kub instability
Qhov ntom ntom tsis sib haum lossis tsim tsis tsim nyog
Lub sijhawm kho tsis txaus
Kev daws:
Stabilize pwm kub thiab ntau lawm chav nyob
Kho lub sij hawm demold thiab tshaj tawm - txheej txheem kho
Siv cov qauv tsim los rau kev tswj kom ruaj khov
Teeb meem 3: Cov Demolding tsis zoo / nplaum nplaum
Cov ntsiab lus tshawb nrhiav:
PU ib leeg daig hauv pwm, tsis zoo demolding PU txhaj, nplaum PU ib leeg nto.
Tej yam ua rau:
Cov tshuaj tiv thaiv tsis tiav vim qhov kub thiab txias
Tsis raug catalyst tshuav nyiaj li cas
Kab mob pwm nto
Tso tus neeg sawv cev tsis sib haum
Kev daws:
Tswj cov khoom thiab pwm kub
Siv qhov tseeb tso tus neeg sawv cev system
Paub meej tias reactivity profile (cream / gel / demold time) ua ntej ntau lawm
Ib tug txhim khu kev qhaPU raw khoom tsumyuav tsum pab koj optimize lub sij hawm voj voog yam tsis muaj kev txi zoo.
Teeb meem 4: Tsis ruaj khov Hardness los yog ntom ntawm Batches
Cov ntsiab lus tshawb nrhiav:
PU ib leeg hardness inconsistent, PU ib leeg density fluctuation, polyurethane system batch variation.
Tej yam ua rau:
Cov khoom siv raw tsis sib xws
Kev tswj tsis zoo piv hauv cov twj metering
Cia kub hloov pauv cuam tshuam rau viscosity
Mixing taub hau hnav thiab tsim kua muag
Kev daws:
Ua haujlwm nrog tus neeg muag khoom uas ua kom cov khoom sib xws thiab QC
Tsis tu ncua calibrate twj thiab saib xyuas cov nqi ntws
Stabilize cia tej yam kev mob kom viscosity kwv yees
Teeb meem 5: Cov ntxhiab tsw thiab VOC Kev txhawj xeeb
Cov ntsiab lus tshawb nrhiav:
PU ib tus ntxhiab tsw, tsis tshua muaj ntxhiab polyurethane system, VOC polyurethane ib leeg khoom.
Cov ntxhiab tsw tuaj yeem cuam tshuam rau cov khoom tsim, kev ua haujlwm kub, lossis kev kho tsis tiav. Xaiv ib qho kev tswj xyuas, siv cov kev kho kom raug, thiab ua kom lub qhov cua kom zoo yuav pab txo kom tsis txhob muaj ntxhiab tsw. Rau cov hom lag luam uas yuav tsum tau ua raws li cov cai nruj, cov ntaub ntawv xa khoom thiab cov khoom siv pob tshab yog qhov tseem ceeb tshwj xeeb.
Dab tsi "Professional Supplier" txhais tau tias tiag tiag rau PU Sole Materials
Thaum xaivpolyurethane raw kua rau khau khau, cov neeg siv khoom tsis yog yuav cov tshuaj xwb -lawv yuav cov khoom ruaj khov thiab kev daws teeb meem. Tus kws tshaj lij exporter yuav tsum muab:
ruaj khovPU ib leeg systemmuab
Clear cov ntaub ntawv technical thiab pom zoo ua qhov rais
Ntim haum rau export logistics
Kev them nyiaj yug rau kev daws teeb meem tsis raug thiab kev hloov pauv
