Yog koj tab tom nrhiav"CPU Casting Defects", "Bubbles nyob rau hauv cam khwb cia polyurethane", "Nqus degassing polyurethane elastomer", "pot life control", los yog"cam khwb cia urethane curing kub", koj twb nyob ze rau lub ntsiab lus tseem ceeb: zoo CPU qhov chaw los ntawm ob qho tib sizoo chemistrythiabua kom raug.
CPU tsim hauv paus (thiab vim li cas cov txheej txheem tseem ceeb)
Cast polyurethane elastomers yog tsim thaumprepolymer react nrog saw extenders, ces lub kaw lus kho rau hauv 3D network qauv. Thaum lub sijhawm tsim khoom, cov kua sib xyaw tseem ua haujlwm tau rau lub sijhawm txwv (lauj kaub) thiab tom qab ntawd solidifies. Hauv ntau qhov system,siab kub curingpab txhim kho qhov kawg network zog thiab durability.
Plaub yam teeb meem casting thiab cov tswv yim daws teeb meem
1) Cua npuas / voids
Cov tsos mob:pinholes, internal voids, txo tensile zog, tsis ua hauj lwm ntxov.
Kev daws:
Sivnqus tsev degassingtom qab sib tov (tshwj xeeb tshaj yog rau tuab ncuav)
Tswj kom raugviscosity thiab pouring kub
Khaws cov pwm kom qhuav thiab preheated thaum xav tau
Lub tshuab nqus tsev degassing thiab lub sij hawm nyob rau hauv lub lauj kaub lub neej yog feem ntau hais txog kev coj ua.
2) Lub neej luv luv / ntxov ntxov gelling
Cov tsos mob:tsis zoo txaus, tsis tiav pwm sau, weld kab.
Kev daws:
Xaiv qhov system / curative ua ke nrog lub lauj kaub ua haujlwm rau koj qhov loj
Tswj cov khoom kub (kub heev feem ntau shortens lub neej lauj kaub)
Siv cov kev sib xyaw kom zoo kom tsis txhob muaj cov hotspots hauv zos
Cov ntaub ntawv ua haujlwm sib tham txog qhov kev xaiv curative cuam tshuam rau kev kho tus nqi thiab lub neej lub lauj kaub, tshwj xeeb tshaj yog nyob rau hauv ntau tsev neeg prepolymer.
3) Cov dej noo- cuam tshuam txog qhov tsis xws luag
Cov tsos mob:foaming, npuas, inconsistent hardness.
Kev daws:
Khaws cov ntaub ntawv raw khoom kaw; siv daim pam qhuav nitrogen yog tias ua tau
Qhuav fillers / pigments; khaws cov pwm kom huv si thiab qhuav
Nco ntsoov tias cov tshuab sib txawv tuaj yeem ua rau pom qhov sib txawv ntawm cov dej noo thaum lub sijhawm ua haujlwm
4) Raws li - kho los yog tsis sib xws hardness
Cov tsos mob:tacky nto, tsis muaj zog, tsis ruaj khov compression teeb.
Kev daws:
Ua raws li kev pom zoocuring kub / sijhawm
Xav txogpost- khokom maximize mechanical zog
Xyuas kom meej qhov sib piv tswj thiab kev sib xyaw kom raug
Vim li cas cov txheej txheem no tswj tau txhais ua ROI zoo dua
CPU ua haujlwm zoo dua txhais tau tias:
Zoo sib xwsNtug hardness
Siab dualub zog tsim kua muagthiababrasion tsis kam
Tsawg tus nqi seem thiab tsawg dua cov neeg siv khoom tsis txaus siab
Lub neej ua haujlwm ntev dua hauv cov log, cov menyuam, cov ntsaws ruaj ruaj, thiab hnav cov khoom siv
Ua haujlwm nrog tus neeg muag khoom uas nkag siab txog kev tsim khoom
Shandong Beiqiao txhawb nqa cov neeg siv khoom tsis yog tsuas yog nrog CPU cov khoom siv, tab sis kuj nrog cov lus qhia ua tau zoo ntawm kev sib tw casting-cov khoom kub, sib tov, degassing, thiab kho- yog li koj tuaj yeem ua tiav qhov zoo ntawm qhov ntsuas.
