Cov txheej txheem pultrusion yog ib txoj kev nruam molding uas cov carbon fiber impregnated nrog kua nplaum yog dhau los ntawm pwm thaum kho.Txoj kev no tau siv los tsim cov khoom lag luam nrog cov duab sib dhos ua ke, yog li nws tau rov nkag siab tias yog ib txoj hauv kev tsim nyog rau kev tsim khoom loj thiab txhim kho kev tsim khoom, thiab kev siv kuj nce ntxiv.Txawm li cas los xij, cov teeb meem xws li tev, tawg, npuas, thiab xim sib txawv feem ntau tshwm sim ntawm qhov chaw ntawm cov khoom thaum lub sij hawm pultrusion txheej txheem.
Flaking
Thaum cov khoom kho tau tawm ntawm cov pwm ntawm qhov chaw, qhov tshwm sim no hu ua flaking lossis flaking.
Kev daws:
1. Ua kom qhov kub ntawm qhov nkag mus rau qhov kawg ntawm cov pwm thaum ntxov ntawm cov khoom kho.
2. Txo cov kab ceev kom cov resin kho ua ntej.
3. Nres kab rau kev ntxuav (30 mus rau 60 vib nas this).
4. Ua kom cov concentration ntawm qis kub pib.
Blister
Thaum blistering tshwm sim ntawm qhov chaw ntawm qhov chaw.
Kev daws:
1. Ua kom qhov kub thiab txias ntawm qhov kawg pwm ua kom cov resin kho sai
2. Txo cov kab nrawm, uas muaj cov txiaj ntsig zoo ib yam li cov kev ntsuas saum toj no
3. nce qib ntawm kev txhawb nqa.Foaming feem ntau tshwm sim los ntawm voids uas ua los ntawm cov iav fiber ntau tsawg.
Nto tawg
Cov kab nrib pleb yog tshwm sim los ntawm ntau qhov shrinkage.
Kev daws:
1. Ua kom cov pwm kub kom ua kom ceev ceev
2. Txo cov kab nrawm, uas muaj cov txiaj ntsig zoo ib yam li cov kev ntsuas saum toj no
3. Ua kom qhov chaw thau khoom lossis iav fiber ntau cov ntsiab lus ntawm cov muab tub lim kom ua kom lub zog ntawm cov resin-nplua nuj nto, yog li txo qis shrinkage, kev ntxhov siab thiab tawg.
4. Ntxiv cov pawm los yog daim ntaub thaiv rau qhov chaw
5. Ua kom cov ntsiab lus ntawm qhov ntsuas kub qis lossis siv cov pib pib qis dua qhov ntsuas kub tam sim no.
Sab hauv tawg
Cov kab nrib pleb sab hauv feem ntau cuam tshuam nrog ntu tuab heev, thiab cov kab nrib pleb tuaj yeem tshwm hauv nruab nrab ntawm lub laminate lossis ntawm qhov chaw.
Kev daws:
1. Ua kom qhov kub ntawm qhov khoom noj kawg kom kho cov resin ua ntej
2. Txo cov pwm kub ntawm qhov kawg ntawm cov pwm thiab siv nws los ua lub dab dej kub kom txo tau qhov exothermic ncov
3. Yog tias cov pwm kub tsis tuaj yeem hloov pauv, ua kom cov kab nrawm kom txo tau qhov kub ntawm cov txheej txheem sab nraud ntawm qhov chaw thiab lub siab exothermic, yog li txo cov thermal stress.
4. Txo cov theem pib, tshwj xeeb tshaj yog cov pib kub kub.Qhov no yog qhov kev daws teeb meem zoo tshaj plaws, tab sis xav tau qee qhov kev sim los pab.
5. Hloov lub siab kub pib nrog ib qho pib nrog qis exotherm tab sis zoo curing nyhuv.
Chromatic aberration
Cov pob kub tuaj yeem ua rau tsis sib xws, ua rau chromatic aberration (aka xim hloov)
Kev daws:
1. Tshawb xyuas lub rhaub kom paub tseeb tias nws nyob hauv qhov chaw kom tsis txhob muaj qhov kub tsis sib xws ntawm qhov tuag
2. Tshawb xyuas cov khoom sib xyaw kom ntseeg tau tias cov khoom ntim thiab / lossis cov xim tsis sib haum lossis sib cais (xim txawv)
Tsawg bus hardness
Tsawg barcol hardness;vim kev kho tsis tiav.
Kev daws:
1. Txo cov kab nrawm kom nrawm rau kev kho ntawm cov resin
2. Ua kom cov pwm kub tuaj yeem txhim kho tus nqi curing thiab curing degree hauv pwm
3. Tshawb xyuas cov kev sib xyaw ua ke uas ua rau cov yas ntau dhau
4. Tshawb xyuas lwm yam kab mob xws li dej lossis cov xim uas tuaj yeem cuam tshuam rau tus nqi kho
Lus Cim: Barcol hardness nyeem ntawv yuav tsum tsuas yog siv los sib piv cov kev kho nrog tib cov resin.Lawv tsis tuaj yeem siv los sib piv cov kev kho mob nrog cov resins sib txawv, vim cov resins sib txawv tau tsim nrog lawv tus kheej glycols thiab muaj qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv.
Cua npuas los yog pores
Cov npuas cua los yog qhov hws tuaj yeem tshwm rau ntawm qhov chaw.
Kev daws:
1. Tshawb xyuas seb cov dej vapor thiab cov kuab tshuaj ntau dhau yog tshwm sim thaum sib xyaw lossis vim cua sov tsis raug.Dej thiab cov kuab tshuaj boil thiab evaporate thaum lub sij hawm exothermic txheej txheem, ua npuas los yog pores ntawm qhov chaw.
2. Txo cov kab ceev, thiab/los yog nce pwm kub, kom zoo dua kov yeej qhov teeb meem no los ntawm kev ua kom cov resin hardness.
3. Siv lub npog ntsej muag los yog lub ntsej muag zoo nkauj.Qhov no yuav ntxiv dag zog rau cov resin saum npoo thiab pab tshem tawm cov npuas los yog cov pores.
4. Ntxiv cov pawm los yog daim ntaub thaiv rau qhov chaw.
