Cov txheej txheem pultrusion yog ib txoj kev molding tas mus li uas cov carbon fiber impregnated nrog kua nplaum raug dhau los ntawm pwm thaum kho. Txoj kev no tau siv los tsim cov khoom nrog cov duab sib txawv, yog li nws tau rov nkag siab dua li ib txoj kev tsim khoom loj thiab txhim kho kev ua haujlwm ntau lawm, thiab nws siv kuj nce ntxiv. Txawm li cas los xij, teeb meem xws li tev tawv, tawg, npuas, thiab qhov sib txawv xim feem ntau tshwm sim ntawm qhov chaw ntawm cov khoom thaum lub sijhawm pultrusion.
Kev tawg ua tej daim me me
Thaum cov khoom me me ntawm cov tshuaj kho tau tawm ntawm pwm ntawm qhov chaw ntawm qhov, qhov xwm txheej no hu ua flaking lossis flaking.
Kev daws teeb meem:
1. Ua kom qhov kub ntawm qhov nkag ntawm qhov pwm thaum ntxov ntawm cov tshuaj kho kom nce ntxiv.
2. Txo qhov ceev ntawm kab kom cov resin kho sai dua.
3. Kab nres rau kev ntxuav (30 txog 60 vib nas this).
4. Ua kom qhov concentration ntawm qhov kub qis pib.
Cov pob khaus
Thaum muaj blistering tshwm sim rau ntawm qhov chaw ntawm qhov.
Kev daws teeb meem:
1. Ua kom qhov kub ntawm qhov pwm kawg ntawm qhov nkag kom ua rau cov resin kho sai dua
2. Txo qhov ceev ntawm kab, uas muaj cov txiaj ntsig zoo ib yam li cov kev ntsuas saum toj no
3. Ua kom cov khoom siv txhawb zog ntxiv. Feem ntau cov khoom ua npuas dej yog tshwm sim los ntawm cov qhov khoob uas tshwm sim los ntawm cov iav fiber tsawg.
Cov kab nrib pleb ntawm qhov chaw
Cov kab nrib pleb ntawm qhov chaw yog tshwm sim los ntawm kev ntsws ntau dhau.
Kev daws teeb meem:
1. Ua kom qhov kub ntawm pwm nce ntxiv kom ua kom cov pwm kho sai dua
2. Txo qhov ceev ntawm kab, uas muaj cov txiaj ntsig zoo ib yam li cov kev ntsuas saum toj no
3. Ua kom cov khoom thauj lossis cov iav fiber ntau ntxiv rau ntawm cov khoom siv kom ua rau cov tawv ntawm cov khoom nplua nuj, yog li txo qhov ntsws, kev ntxhov siab thiab kev tawg.
4. Ntxiv cov ntaub pua chaw lossis cov ntaub thaiv rau ntawm qhov chaw
5. Ua kom cov ntsiab lus ntawm cov khoom pib kub qis dua lossis siv cov khoom pib qis dua qhov kub tam sim no.
Qhov tawg sab hauv
Cov kab nrib pleb sab hauv feem ntau yog txuam nrog ib ntu tuab dhau, thiab cov kab nrib pleb yuav tshwm sim hauv nruab nrab ntawm lub laminate lossis ntawm qhov chaw.
Kev daws teeb meem:
1. Ua kom qhov kub ntawm qhov kawg pub kom kho cov resin ua ntej dua
2. Txo qhov kub ntawm pwm thaum kawg ntawm pwm thiab siv nws ua lub dab dej kub kom txo qhov kub siab tshaj plaws.
3. Yog tias qhov kub ntawm pwm tsis tuaj yeem hloov pauv, nce qhov ceev ntawm kab kom txo qhov kub ntawm sab nraud ntawm qhov thiab lub ncov exothermic, yog li txo cov kev ntxhov siab thermal.
4. Txo cov theem ntawm cov initiators, tshwj xeeb tshaj yog cov initiators kub siab. Qhov no yog qhov kev daws teeb meem zoo tshaj plaws mus tas li, tab sis xav tau qee qhov kev sim los pab.
5. Hloov lub tshuab pib kub siab nrog lub tshuab pib uas muaj exotherm tsawg tab sis cov nyhuv kho zoo dua.
Kev hloov pauv ntawm cov xim
Cov chaw kub kub tuaj yeem ua rau tsis sib xws, ua rau muaj kev hloov pauv xim (aka kev hloov xim)
Kev daws teeb meem:
1. Xyuas lub tshuab cua sov kom paub tseeb tias nws nyob hauv qhov chaw kom tsis muaj qhov kub tsis sib npaug ntawm lub pwm
2. Xyuas cov khoom sib xyaw ua ke kom paub tseeb tias cov khoom sau thiab / lossis cov xim tsis sib cais lossis sib cais (qhov sib txawv ntawm xim)
Kev nyuaj ntawm lub tsheb npav qis
Qhov barcol hardness qis; vim yog kev kho tsis tiav.
Kev daws teeb meem:
1. Txo qhov ceev ntawm kab kom ua kom cov tshuaj kho sai dua
2. Ua kom qhov kub ntawm pwm nce ntxiv kom txhim kho qhov nrawm thiab qib kev kho hauv pwm
3. Tshawb xyuas seb puas muaj cov qauv sib xyaw ua ke uas ua rau cov yas ntau dhau
4. Tshawb xyuas seb puas muaj lwm yam khoom tsis huv xws li dej lossis cov xim uas tuaj yeem cuam tshuam rau qhov kho sai.
Lus Cim: Cov kev nyeem Barcol hardness tsuas yog siv los sib piv cov kho nrog tib cov resin. Lawv tsis tuaj yeem siv los sib piv cov kho nrog cov resins sib txawv, vim tias cov resins sib txawv yog tsim los ntawm lawv tus kheej glycols tshwj xeeb thiab muaj qhov tob sib txawv ntawm kev sib txuas.
Cov npuas cua lossis cov qhov hws
Tej zaum yuav muaj cov pa npuas lossis cov qhov hws tshwm sim rau ntawm qhov chaw.
Kev daws teeb meem:
1. Xyuas seb puas muaj cov dej thiab cov tshuaj yaj ntau dhau thaum lub sijhawm sib tov lossis vim tsis ua kom sov zoo. Dej thiab cov tshuaj yaj yuav npau thiab ua pa thaum lub sijhawm exothermic, ua rau muaj npuas lossis qhov hws ntawm qhov chaw.
2. Txo qhov ceev ntawm txoj kab, thiab/lossis nce qhov kub ntawm pwm, kom kov yeej qhov teeb meem no zoo dua los ntawm kev ua kom cov resin tawv dua.
3. Siv daim ntaub npog saum npoo av los yog daim ntaub mos mos rau saum npoo av. Qhov no yuav ua rau cov roj hmab ntawm saum npoo av muaj zog thiab pab tshem tawm cov npuas cua lossis cov qhov hws.
4. Ntxiv cov ntaub pua chaw lossis cov ntaub thaiv rau cov khoom.
