Qhov zoo thiab qhov tsis zoo ntawm ob yog piv raws li hauv qab no:
Txhais tes nteg-up yog qhib-pwm cov txheej txheem uas tam sim no siv rau 65% ntawmIav Fibersiv cov composites. Nws cov txiaj ntsig yog tias nws muaj qib kev ywj pheej ntawm cov pwm, cov khoom lag luam yog qhov muaj zog, cov khoom lag luam raug lees paub los ntawm kev ua lag luam, thiab kev nqis peev yog tsawg. Yog li nws yog qhov tsim nyog tshwj xeeb rau cov tuam txhab me me, tab sis kuj yog rau cov tubrog nkoj thiab aerospace, qhov twg nws yog feem ntau yog ib feem ntau. Txawm li cas los xij, tseem muaj cov teeb meem ntawm cov teeb meem hauv cov txheej txheem no. Yog hais tias lub volatile cov organic compound (voc) emission ntau npaum li tus qauv, nws yog qhov yooj yim rau cov neeg ua haujlwm pub dawb, nws yog qhov kev ua tau zoo ntawm cov khoom noj muaj txiaj ntsig, thiab cov khoom lag luam tsis muaj pov tseg thiab siv nyob rau hauv ib tug ntau npaum li cas, tshwj xeeb tshaj yog cov khoom. Qhov zoo yog tsis ruaj khov. Kev faib ua feem ntawmIav Fiber Thiab Resin, cov tuab tuab ntawm cov seem, cov nqi tsim khoom ntawm txheej, thiab cov neeg teb xov tooj ntawm cov txheej txheem los ntawm tus neeg teb xov tooj, thiab tus neeg teb xov tooj muaj cov thev naus laus zis zoo dua qub, muaj kev paub thiab zoo.Lub resinCov ntsiab lus ntawm tes txheej txheej yog feem ntau nyob ib ncig ntawm 50% -70%. Lub suab tawm ntawm cov pwm qhib ntau dua li 500ppm, thiab volatilization ntawm styrene yog siab li 35% -45% ntawm cov nyiaj siv. Cov kev cai ntawm ntau lub tebchaws yog 50-100ppm. Tam sim no, feem ntau cov neeg txawv teb chaws siv cyclopentadiene (DCPD) lossis lwm yam qis qis dua cov resins, tab sis tsis muaj qhov zoo hloov rau styrene ua monomer.
Fiberglass Mat Tes Tsho Txheej Txheem
Lub Tshuab Nqus TsevCov txheej txheem qhia yog tus txheej txheem tsim nyog siv tsim tau hauv 20 xyoo dhau los, tshwj xeeb tshaj yog haum rau kev tsim cov khoom loj ntawm cov khoom lag luam loj. Nws cov txiaj ntsig yog raws li hauv qab no:
(1) Cov khoom muaj kev ua tau zoo thiab muaj txiaj ntsig zoo.Cov ntaub ntawv zoo ib yamiav yasCov ntaub ntawv raw, lub zog, txhav thiab lwm yam khoom siv ntawm lub tshuab nqus tsev tuaj yeem raug txhim kho los ntawm ntau tshaj 30% -50 piv nrog txhais tes nteg ntaug (rooj 1). Tom qab cov txheej txheem yog stabilized, cov txiaj ntsig tuaj yeem ze rau 100%.

(2) Cov khoom lag luam zoo yog qhov ruaj khov thiab qhov ua tiav yog qhov zoo.Cov khoom zoo yog tsis tshua muaj kev cuam tshuam los ntawm cov neeg ua haujlwm, thiab muaj qib siab ntawm kev sib xws, thiab muaj qhov sib xyaw ua ke lossis nruab nrab. Cov ntsiab lus fiber ntau ntawm cov khoom tau muab tso rau hauv cov pwm raws li cov nyiaj rov qab ua ntej muab cov khoom siv rov qab ua ntej, thiab cov khoom siv tsis sib xws thiab cov khoom lag luam yog Zoo dua li txhais tes txheej txheej txheem txheej txheem. ntau dua, thiab tsawg dua qhov tsis xws luag.
(3) Cov kev ua tau zoo dhau los tiv thaiv kev ua tau zoo, uas tuaj yeem txo qhov hnyav ntawm cov qauv.Vim yog cov ntsiab lus muaj fiber ntau, porosity tsawg thiab cov khoom lag luam siab, tshwj xeeb cov khoom muaj zog, lub zog nkees ua rau cov khoom lag luam tau zoo dua. Nyob rau hauv cov ntaub ntawv ntawm tib lub zog lossis pob zeb yuav tsum tau, cov khoom lag luam ua los ntawm lub tshuab nqus tsev los ntawm cov txheej txheem muaj peev xwm txo qhov hnyav ntawm tus qauv.
(4) ib puag ncig tus phooj ywg.Lub nqus plua plav Resin Txoj kev ua kauj ruam yog qhov chaw kaw pwm uas tsis tshua muaj cov organic thiab lom cov pa paug paug tau tawm hauv lub hnab nqus plua plav. Tsuas yog cov nyiaj tau los ntawm cov neeg nqus tsev tawm thaum lub tshuab nqus tsev yog qhov cua (lim) thiab cov cob muaj sia tawm. VOC emissions tsis tshaj tus qauv ntawm 5PPM. Qhov no kuj txhim kho kev ua haujlwm ib puag ncig rau cov neeg ua haujlwm, ruaj khov rau kev ua haujlwm, thiab nthuav dav cov ntaub ntawv muaj.
(5) Cov khoom siv ncaj ncees yog qhov zoo.Lub tshuab nqus tsev cob qhia cov saw, cov khoom sib txawv ntawm cov khoom lag luam, cov khoom lag luam loj xws li kiv cua hoods, nkoj Hulls thiab SuperStructures tuaj yeem tsim tawm.
(6) txo cov khoom siv raw thiab ua haujlwm.Nyob rau hauv tib txoj kev pw, tus nqi ntawm Resin yog txo los ntawm 30%. Tsawg cov khib nyiab, cov khoom ploj poob qis tsawg dua 5%. Muaj kev ua haujlwm siab, ntau dua 50% kev ua haujlwm txuag piv nrog cov txheej txheem nteg ntaug. Tshwj xeeb tshaj yog nyob rau hauv moulding ntawm loj thiab complex geometries ntawm cov qhaub cij thiab kev txuag cov khoom siv tau ntau dua. Piv txwv li, hauv kev tsim cov hluav taws xob ntsug hauv kev lag luam aviation los ntawm 365 yog qhov hnyav ntawm cov khoom lag luam nyob tsis hloov, thiab kev ua tau zoo dua.
(7) Cov khoom lag luam yog qhov zoo.Lub sab qhov tseeb (tuab) ntawm lub tshuab nqus tsev cob cov txheej txheem kev tshawb xyuas cov khoom lag luam zoo dua li ntawm cov khoom nteg ua ke. Nyob rau hauv tib tus kab, lub thickness ntawm General Retin diffation tshuab cov khoom lag luam yog 2/3 ntawm qhov ntawd ntawm cov khoom nteg nteg. Cov khoom thickness sib txawv yog hais txog ± 10%, thaum cov txheej txheem txuas tes feem ntau ± 20%. Lub flatness ntawm cov khoom nto yog zoo dua li ntawm cov khoom nteg nteg. Sab hauv phab ntsa ntawm cov khoom lag luam hood ntawm lub tshuab nqus tsev cob qhia cov txheej txheem txheej txheej txheej txheej txheej txheej uas yog txheej txheej saum npoo av, uas tsis tas yuav tsum muaj lub tsho tiv no. Txo cov zog thiab cov khoom siv rau cov sanding thiab cov txheej txheem tha xim.
Tau kawg, tam sim no nqus khaub ncaws qhia cov txheej txheem qhia tseem muaj qee yam shortcomings:
(1) cov txheej txheem npaj npaj yuav siv sijhawm ntev thiab yog cov nyom ntau dua.Kev tso tawm kom zoo, kev tso kawm ntawm kev tshaj tawm kev sib txawv, cov leeg ua si, lub tshuab nqus tsev zoo, thiab lwm yam. Yog li ntawd, rau cov khoom lag luam me, cov txheej txheem lub sijhawm ntev dua ntawm cov txheej txheem ua ke.
(2) Tus nqi tsim yog cov nqi siab dua thiab ntau dua pov tseg yog tsim.Cov ntaub ntawv xws li cov tshuab nqus tsev ua yeeb yaj kiab, kev ua kom muaj zog, thiab ntau yam tau siv tau yooj yim, yog li cov nqi tsim yog siab dua ntawm cov txheej txheem nteg tes. Tab sis cov khoom loj dua, qhov me me qhov sib txawv. Nrog rau cov chaw hauv zos ntawm cov ntaub ntawv tso tawm, cov nqi no tau txais me dua thiab me dua. Cov kev tshawb fawb tam sim no ntawm cov ntaub ntawv siv tam sim no uas tuaj yeem siv ntau zaus yog kev qhia ntawm cov txheej txheem no.
(3) kev tsim qauv muaj qee qhov phom sij.Tshwj xeeb tshaj yog rau cov khoom loj thiab cov txheej txheem sib xyaw ua ke, ib zaug resin Txoj kev lis ntshav tsis, cov khoom yog ib qho yooj yim yuav tsum tau txhuam.
Yog li ntawd, zoo dua kev tshawb fawb ua ntej, nruj txheej txheem tswj cov txheej txheem thiab siv kev ntsuas kev kho kom haum rau cov txheej txheem ua tiav.
