Pwm yog cov khoom siv tseem ceeb rau kev tsim cov khoom FRP. Pwm muaj peev xwm muab faib ua hlau, txhuas, cement, roj hmab, paraffin, FRP thiab lwm yam raws li cov khoom siv. Pwm FRP tau dhau los ua pwm siv ntau tshaj plaws hauv cov txheej txheem FRP vim lawv yooj yim tsim, yooj yim nrhiav tau cov khoom siv raw, pheej yig, lub voj voog tsim khoom luv luv thiab yooj yim txij nkawm.
Cov pwm FRP thiab lwm cov pwm yas uas xav tau qhov chaw saum npoo yog tib yam, thiab feem ntau qhov chaw ntawm pwm yog ib theem siab dua qhov chaw tiav ntawm cov khoom. Qhov zoo dua ntawm qhov chaw pwm, qhov luv dua lub sijhawm molding thiab lub sijhawm tom qab ua tiav ntawm cov khoom, qhov zoo dua ntawm qhov chaw ntawm cov khoom, thiab lub neej ua haujlwm ntev dua ntawm cov pwm. Tom qab cov pwm xa mus rau kev siv, txhawm rau kom tswj tau qhov zoo ntawm qhov chaw ntawm cov pwm, kev saib xyuas cov pwm yuav tsum tau ua kom zoo. Kev saib xyuas pwm suav nrog: ntxuav qhov chaw pwm, ntxuav cov pwm, kho qhov puas tsuaj, thiab txhuam cov pwm. Kev saib xyuas pwm raws sijhawm thiab zoo yog qhov pib zoo tshaj plaws rau kev saib xyuas pwm. Tsis tas li ntawd, txoj kev saib xyuas pwm kom raug yog qhov tseem ceeb. Cov lus hauv qab no qhia txog ntau txoj kev saib xyuas thiab cov txiaj ntsig kev saib xyuas sib xws.
Cov txheej txheem txij nkawm sib txawv rau cov pwm sib txawv yog raws li nram no
①Cov pwm tshiab lossis cov pwm uas tsis tau siv ntev
Ua ntej tshaj plaws, ntxuav thiab tshuaj xyuas qhov chaw ntawm pwm, thiab ua qhov kho kom zoo rau cov khoom puas tsuaj thiab tsis tsim nyog ntawm pwm. Tom ntej no, siv cov kuab tshuaj los ntxuav qhov chaw pwm, thiab tom qab ntawd siv lub tshuab polishing thiab cov tshuaj txhuam polishing los txhuam qhov chaw pwm ib lossis ob zaug tom qab ziab. Ua kom tiav kev siv tshuaj pleev xim thiab txhuam peb zaug sib law liag, tom qab ntawd siv tshuaj pleev xim dua, thiab txhuam dua ua ntej siv.
②Cov pwm siv
Ua ntej tshaj plaws, xyuas kom meej tias cov pwm raug pleev xim thiab txhuam txhua peb zaug, thiab cov khoom uas yooj yim puas thiab nyuaj rau rhuav tshem yuav tsum tau pleev xim thiab txhuam ua ntej txhua zaus siv. Qhov thib ob, rau ib txheej ntawm cov khoom txawv teb chaws (tej zaum yuav yog polyphenylene lossis quav ciab) uas yooj yim tshwm sim ntawm qhov chaw ntawm cov pwm uas tau siv ntev, nws yuav tsum tau ntxuav raws sijhawm. Maj mam khawb tawm), thiab qhov txhuam raug rhuav tshem raws li cov pwm tshiab.
③Hauv cov pwm tawg
Rau cov pwm uas kho tsis tau raws sijhawm, koj tuaj yeem siv cov khoom siv quav ciab thiab lwm yam khoom uas yooj yim deformed thiab yuav tsis cuam tshuam rau kev kho ntawm lub tsho gel los sau thiab tiv thaiv cov khoom puas tsuaj ntawm cov pwm, thiab txuas ntxiv siv. Rau cov uas kho tau raws sijhawm, qhov puas tsuaj yuav tsum tau kho ua ntej, thiab qhov kho yuav tsum tau kho los ntawm tsawg kawg 4 tus neeg (ntawm 25 ° C). Qhov kho yuav tsum tau polished, polished thiab demolded ua ntej nws tuaj yeem siv.
Kev saib xyuas ib txwm thiab raug ntawm qhov chaw pwm txiav txim siab lub neej ua haujlwm ntawm pwm, qhov ruaj khov ntawm qhov zoo ntawm cov khoom, thiab qhov ruaj khov ntawm kev tsim khoom, yog li yuav tsum muaj tus cwj pwm zoo ntawm kev saib xyuas pwm.
