Ua Thiab Kev daws rau Huab Cua Npuas Thiab Delamination hauv Tes Lay -txheej txheem Fiberglass Mat
Thaum ua tes nteg - ntawmchopped strand lev, huab cua npuas thiab delamination feem ntau yuav tshwm sim vim lub lev xoob kev ntxhib los mos thiab tsis sib xws impregnation tus nqi. Kab lus no yuav tsom mus rau plaub yam tseem ceeb: cov khoom siv raw, txoj kev ua haujlwm, ib puag ncig, thiab kev kho tshuab. Nws yuav piav qhia meej txog cov laj thawj thiab muab cov kev daws teeb meem los pab koj kom tsis txhob muaj teeb meem hauv koj cov txheej txheem tsim khoom.
I. Ua ntej, nkag siab qhov txawv ntawm npuas thiab delamination.
Ntau tus neeg ua haujlwm tsis meej pem npuas thiab delamination thaum tsim kho, tab sis lawv cov laj thawj, tshwm sim, thiab kev phom sij txawv.
npuas: Cov no feem ntau yog cov voids me me sab hauv lossis ntawm qhov chaw ntawm cov khoom, pom ntawm qhov muag liab qab, thiab tsa rau qhov kov. Lawv feem ntau cuam tshuam cov tsos thiab airtightness.
Delamination: Qhov no tshwm sim thaum cov khaubncaws sab nraud povtseg tsis ruaj khov, ua rau delamination thiab hollow thaj chaw. Ib lub teeb kais tsim lub suab hollow. Nws yog ib qho kev tsis xws luag uas ncaj qha txo lub zog.
Ob qho tib si feem ntau tshwm sim ib txhij: kev tshem tawm npuas tsis tiav → tsis txaus resin impregnation → kawg ua rau delamination, ib qho "faj fab saw."
II. Cov npuas hauv Tes Lay- nce: 7 Qhov Tseem Ceeb + Cov Kev daws teeb meem sib xws
Cov npuas yog qhov teeb meem feem ntau hauv tes nteg- txheej txheem. Cov hauv paus ntsiab lus yog qhov tsis txaus impregnation, cua ntxiab, thiab qhov cua tsis zoo.
1. Resin tuab heev, viscosity siab dhau
High resin viscosity ua rau qeeb ntws, tiv thaiv kom ceev impregnation ntawm fiberglass lev. Huab cua yog daig hauv cov fibers, tsim cov npuas me me.
Kev daws: Ntxiv cov thinner tsim nyog los yog reactive thinner los tswj viscosity; preheat resin ua ntej lub caij ntuj no tsim.
2. Kev txiav txim tsis raug ntawm kev siv cov nplaum thiab dov:
Tso cov kev xav ua ntej siv cov resin feem ntau yuav ntxiab cua.
Kev daws: Ua raws li tus qauv txheej txheem ntawm kev thov primer ua ntej → tso cov kev xav → thov cov nplaum dua → dov kom tshem tawm cua.
3. Cov cuab yeej dov tsis raug lossis tsis txaus siab:
Cov menyuam yaus uas nyuaj dhau, pw tsaug zog ntev ntev, lossis siv lub siab tsis txaus yuav tsis tshem tawm huab cua los ntawm kev xav.
Kev daws: Siv lub tshuab defoaming los yog cov roj hmab tawv tawv, dov ntau zaus hauv ib qho kev taw qhia, tsis txhob rov qab -thiab- tawm mus.
4. Damp los yog oily tws strand lev:
Kev ntub dej los yog cov kab mob paug yuav cuam tshuam impregnation thiab tsim cov npuas.
Kev daws: Khaws cov fiberglass kom qhuav; tshawb xyuas cov dej noo thiab av ua ntej siv.
5. Thov tuab heev txheej nplaum:
Yog tias cov nplaum txheej yog tuab heev, cov npuas hauv cov pa tsis tuaj yeem sawv thiab khiav tawm. Kev daws:
6. Kev kho sai heev
Gelging yog ceev heev; huab cua npuas tsis tau khiav ua ntej kho.
Kev daws: Kho qhov sib piv ntawm accelerator thiab hardener kom tsis txhob kho sai ntawm qhov kub thiab txias.
7. Siab Airflow thiab plua plav hauv ib puag ncig
Cua ua rau tawv nqaij ntxov ntxov, sealing cov npuas hauv huab cua.
Kev daws: Ua kom tsis muaj cua, plua plav-dawb, thiab kub-rhiav ruaj khov.
III. Khoom Delamination: 5 Qhov Tseem Ceeb Ua + Kev daws teeb meem zoo
Delamination yog qhov hnyav dua li huab cua npuas thiab sawv cev rau cov nplaum tsis ua haujlwm, feem ntau tshwm sim ntawm cov khaubncaws sab nraud povtseg, ntawm cov ces kaum, thiab hauv cov cheeb tsam sib txawv.
1. Tsis tiav Impregnation ntawm txheej, qhuav Felt, qhuav chaw
Chopted strand lev tsis yog tag nrho impregnated nrog resin, ua rau "qhuav strands," tiv thaiv kev sib txuas ntawm cov khaubncaws sab nraud povtseg.
Kev daws: Xyuas kom txhua txheej ntawm lev yog tag nrho impregnated nrog cov nplaum, tsis muaj cov pob dawb thiab qhuav, ua ntej siv cov txheej txheem tom ntej.
2. Ntau lub sij hawm nruab nrab ntawm txheej txheej
Yog tias txheej txheej dhau los twb tau kho los yog kho ib nrab, tso ib txheej tshiab yuav ua rau delamination.
Kev daws: Tswj cov txheej txheem tso; txuas ntxiv nteg cov txheej tom ntej thaum nws tseem nto qhuav tab sis tsis tag nrho gelled.
3. Qhov nyuaj hauv huab cua Venting ntawm kaum, nkhaus nto, thiab cov qauv tsis yooj yim.
Cov cheeb tsam tsis sib xws yog feem ntau ua rau huab cua hauv hnab ris thiab cov nplaum tsis txaus, ua rau delamination.
Kev daws: Rau thaj chaw nyuaj, siv cov nplaum ua ntej, tom qab ntawd nteg cov kev xav, thiab rov ua dua. Yog tias tsim nyog, txiav qhov qhib kom tshem tawm wrinkles.
4. Tsis raug Resin Proportioning
Lub hardener tsis txaus ua rau kev kho tsis tiav thiab tsis muaj zog interlayer; Tsis txaus accelerator ua rau qeeb curing thiab susceptibility rau delamination vim cuam tshuam.
Kev daws: nruj me ntsis ua raws li qhov sib xyaw ua ke; sib tov tsuas yog yam xav tau; tsis txhob siv cov nplaum uas tas sij hawm.
5. Tsis sib xws lossis Wrinkled Chopped Strand Mat Laying
Wrinkles inevitably ua rau cov nplaum tsis txaus thiab cov hnab ntim cua, thaum kawg ua rau delamination.
Kev daws: Pw lub lev ca, khov kho, thiab wrinkle -dawb; nias cov npoo ruaj khov.
IV. Ua kom tiav Tes Lay-txheej txheej txheem hauv ib qho mus: Cov txheej txheem kev ua haujlwm
Txoj hauv kev zoo tshaj plaws los tshem tawm cov npuas npuas thiab delamination yog ua raws li cov txheej txheem txheem.
1. Pwm Tu: Xyuas kom cov pwm huv si, qhuav, thiab tsis muaj roj. Thov tus neeg sawv cev tso tawm sib npaug.
2. Resin Preparation: Sib tov cov resin, accelerator, thiab hardener raws li qhov piv txwv thiab do kom huv si.
3. Daim ntawv thov Primer: Siv ib txheej nyias ntawm cov nplaum rau ntawm cov pwm saum npoo los txhim kho adhesion.
4. Chopped Strand Mat Laying: Pw lub lev ca, tsis muaj wrinkles los yog warping.
5. Resin Impregnation thiab Rolling: Siv ib txheej ntawm cov nplaum thiab dov nws kom paub meej tias kev ua kom tiav.
6. Daim Ntawv Thov Txheej: Siv ntau lub tsho nyias nyias, dov hla txhua txheej kom tshem tawm cov npuas npuas.
7. Chav Kho Mob Kub Kub: Khaws ib puag ncig ruaj khov thiab tsis txhob cuam tshuam.
V. Summary: Peb Lub Ntsiab Tseem Ceeb rau Kev Ua Tau Zoo Tes Taw -nce
Lub tes nteg- txheej txheem rau chopped strand lev (CSM) tej zaum yuav zoo li yooj yim, tab sis yuav ua tau siab - cov khoom zoo, cov hauv paus ntsiab lus tseem ceeb yog:
Ua ntej, cov resin yuav tsum tau kom huv si impregnated; impregnation tsis txaus yuav inevitably ua rau muaj teeb meem.
Qhov thib ob, huab cua yuav tsum raug tshem tawm tag nrho; tsis tshem tawm cua yuav ua rau huab cua npuas.
Thib peb, cov khaubncaws sab nraud povtseg yuav tsum tsis tu ncua; zam qhov tsis sib xws los yog ntev heev ntawm cov khaubncaws sab nraud povtseg.
Los ntawm kev ua kom peb cov ntsiab lus no tau hais tseg, qhov tsis xws luag xws li huab cua npuas, delamination, hollow thaj chaw, thiab detachment tuaj yeem zam ntau, txhim kho cov khoom zoo li, lub zog, thiab airtightness. Tes nteg-up yog ib qho txheej txheem sib txuas cov kev paub thiab kev saib xyuas kom meej; Ua tib zoo soj ntsuam, kev hloov kho, thiab ua raws li cov qauv yuav ua kom muaj kev sib raug zoo ntawm cov khoom siv fiberglass siab - zoo.
