Cov txheej txheem pultrusion yog lub nruam moulding txoj kev nyob rau hauv uas cov carbon fiber impration imprognegnated nrog kua nplaum tau dhau los ntawm cov pwm thaum kho. Txoj kev no tau siv los tsim cov khoom lag luam nrog cov kab hla kev nyuaj, yog li nws tau rov qab tsim nyog rau cov huab hwm coj tsim nyog thiab txhim kho ntau lawm, thiab nws siv kuj nce ntxiv. Txawm li cas los xij, teeb meem xws li teeling, tawg, npuas, thiab cov xim sib txawv tshwm sim ntawm cov khoom thaum lub sijhawm tus txheej txheem pultrusion.
Npau taws
Thaum hais cov nplais ntawm cov tshuaj resin tuaj tawm ntawm cov pwm tawm ntawm cov npoo ntawm ib feem, qhov tshwm sim no yog hu ua flaking lossis flaking.
Kev daws:
1. Nce qhov ntsuas kub ntawm cov inlet pub rau kawg ntawm cov pwm thaum ntxov ntawm lub cured resin.
2. Txo cov kab ceev kom ua rau lub resin kho ua ntej.
3. Nres kab rau kev ntxuav (30 txog 60 vib nas this).
4. Ua kom cov concentration ntawm tsawg ntsuas qhov ntsuas kub.
Lub hlawv
Thaum blistering tshwm sim rau saum npoo ntawm ib feem.
Kev daws:
1. Nce qhov kub ntawm qhov inlet Kawg pwm kom ua rau cov khoom kho kom sai dua
2. Txo cov kab nrawm, uas muaj tib cov txiaj ntsig raws li kev ntsuas saum toj no
3. Nce theem ntawm kev txhawb nqa. Ua npuas ncauj yog feem ntau tshwm sim los ntawm voids tshwm sim los ntawm cov ntsiab lus fiber tsawg.
Nto cracks
Cov kab nrib pleb yog tshwm sim los ntawm ntau dhau shrinkage.
Kev daws:
1. Nce cov pwm kub kom ceev rau txoj kev kho kom ceev
2. Txo cov kab nrawm, uas muaj tib cov txiaj ntsig raws li kev ntsuas saum toj no
3. Nce cov chaw thau khoom lossis cov thawv fiber ntau cov ntsiab lus ntawm kev ua kom nruj ntawm cov chaw so ntawm cov chaw so, yog li txo cov shrinkage, kev ntxhov siab thiab tawg
4. Ntxiv cov ntaub qhwv saum npoo lossis daim ntaub thaiv sab
5. Ua kom cov ntsiab lus ntawm cov pib tsawg lossis siv cov pib qis dua li qhov kub tam sim no.
Sab hauv nrib pleb
Sab hauv cov kab nrib pleb feem ntau cuam tshuam nrog cov tuab tuab dhau, thiab cov kab nrib pleb yuav tshwm sim hauv nruab nrab ntawm lub laminate lossis ntawm saum npoo.
Kev daws:
1. Nce qhov kub ntawm cov khoom noj thaum kawg los kho tus so resin ua ntej
2. Txo cov pwm kub ntawm qhov kawg ntawm cov pwm thiab siv nws ua cua sov kom txo cov ncov siab exothermic
3. Yog tias cov pwm kub hloov tsis tau, nce txoj kab khiav ceev kom txo qhov kub ntawm lub contour ntawm ib feem thiab cov kev ntxhov siab explais, yog li txo cov kev ntxhov siab no.
4. Txo cov qib ntawm cov pib, tshwj xeeb tshaj yog cov pib ntsuas kub siab. Nov yog qhov kev daws teeb meem zoo tshaj plaws, tab sis xav tau qee qhov kev sim kom pab.
5. Hloov lub siab ntsuas kub ua rau lub pib nrog tus pib nrog tshem tawm qis dua tab sis kho cov nyhuv zoo dua.
Chromatic aberration
Cov kub me tuaj yeem ua rau tsis sib thooj, ua rau muaj kev cuam tshuam chromatic (AKA xim hloov)
Kev daws:
1. Txheeb xyuas lub rhaub kom paub tseeb tias nws yog nyob rau hauv qhov chaw kom tsis muaj qhov kub tsis sib luag ntawm txoj kev tuag
2. Khij cov khoom cob qhia sib xyaw kom ntseeg tau tias cov chav sau thiab / lossis pigments tsis khom lossis cais (xim sib txawv)
Tsawg npav lub tsheb loj
Tsawg barcol hardness; Vim tias kev kho tsis tiav.
Kev daws:
1. Txo cov kab ceev ceev kom nrawm ntawm txoj kev kho ntawm lub resin
2. Nce cov pwm kub kom txhim kho tus nqi kho thiab kho qib hauv cov pwm
3. Tshawb xyuas cov khoom sib xyaw ua yeeb yam uas ua rau muaj ntau ntxiv yas
4. Tshawb xyuas lwm yam kev paug xws li dej lossis cov pigments uas tuaj yeem cuam tshuam tus kho mob
Nco tseg: Barcol hardness nyeem yuav tsum tsuas yog siv los sib piv cov tshuaj kho nrog tib lub resin. Lawv tsis tuaj yeem siv los sib piv cov txiaj ntsig sib txawv, raws li cov resins sib txawv yog tsim nrog lawv tus kheej tshwj xeeb glycols thiab muaj qhov sib txawv ntawm cov ntoo khaub lig.
Huab cua npuas lossis pores
Pa cua npuas los yog cov hws yuav tshwm nyob saum npoo.
Kev daws:
1. Kuaj xyuas seb cov dej dej ntau dhau thiab cov kuab tshuaj yog tshwm sim thaum sib xyaw lossis vim yog cua sov tsis zoo. Dej thiab cov kuab cua boil thiab evaporate nyob rau lub sijhawm exothermic, ua rau cov npuas lossis hws nyob saum npoo.
2. Txo cov kab nrawm, thiab / lossis nce cov pwm kub, kom kov yeej cov teeb meem no los ntawm kev nce cov teeb meem saum npoo av tawv tawv.
3. Siv ib qho chaw npog lossis saum npoo. Qhov no yuav ntxiv dag zog rau saum npoo Resin thiab pab tshem tawm huab cua npuas lossis pores.
4. Ntxiv cov ntaub qhwv saum npoo lossis daim ntaub thaiv rau seem.
