Qhov zoo thiab qhov tsis zoo ntawm ob yog muab piv rau hauv qab no:

Tes nteg-up yog txheej txheem qhib-pwm uas tam sim no suav txog 65% ntawmiav fiberreinforced polyester composites. Nws qhov zoo yog tias nws muaj kev ywj pheej zoo hauv kev hloov pauv ntawm cov pwm, pwm tus nqi qis, kev hloov pauv tau zoo, cov khoom lag luam tau lees paub los ntawm kev ua lag luam, thiab kev nqis peev tsawg. Yog li nws yog qhov tshwj xeeb tshaj yog rau cov tuam txhab me me, tab sis kuj yog rau kev lag luam marine thiab aerospace, qhov twg nws feem ntau yog ib feem loj. Txawm li cas los xij, kuj tseem muaj cov teeb meem hauv cov txheej txheem no. Yog hais tias cov volatile organic compound (VOC) emissions tshaj tus qauv, nws muaj kev cuam tshuam zoo rau kev noj qab haus huv ntawm cov neeg ua haujlwm, nws yooj yim rau cov neeg ua haujlwm poob, muaj ntau yam kev txwv rau cov ntaub ntawv tso cai, cov khoom ua tau zoo yog tsawg, thiab cov resin yog nkim. thiab siv ntau npaum li cas, tshwj xeeb tshaj yog cov khoom. Qhov zoo yog tsis ruaj khov. Qhov ratio ntawmiav fiber thiab resin, thickness ntawm qhov chaw, ntau lawm tus nqi ntawm txheej, thiab cov uniformity ntawm txheej yog tag nrho cov cuam tshuam los ntawm tus neeg teb xov tooj, thiab tus neeg teb xov tooj yuav tsum muaj technology zoo dua, kev paub thiab zoo.Cov resinCov ntsiab lus ntawm tes nteg cov khoom yog feem ntau nyob ib ncig ntawm 50% -70%. VOC emission ntawm pwm qhib txheej txheem tshaj 500PPm, thiab volatilization ntawm styrene yog siab li 35% -45% ntawm cov nyiaj siv. Cov kev cai ntawm ntau lub teb chaws yog 50-100PPm. Tam sim no, ntau lub teb chaws txawv teb chaws siv cyclopentadiene (DCPD) los yog lwm yam qis styrene tso resins, tab sis tsis muaj qhov zoo hloov rau styrene li monomer.

Fiberglass lev tes nteg txheej txheem

Lub tshuab nqus tsev resinkev taw qhia cov txheej txheem yog cov txheej txheem tsim nqi qis tsim nyob rau hauv 20 xyoo dhau los, tshwj xeeb tshaj yog tsim rau kev tsim cov khoom loj. Nws qhov zoo yog raws li nram no:

(1) Cov khoom muaj kev ua tau zoo thiab muaj txiaj ntsig zoo.Nyob rau hauv cov ntaub ntawv ntawm tib yamfiberglassraw cov ntaub ntawv, lub zog, nruj thiab lwm yam lub cev lub cev ntawm lub tshuab nqus tsev resin-qhia Cheebtsam yuav txhim kho los ntawm ntau tshaj 30% -50% piv nrog tes nteg-up Cheebtsam (Table 1). Tom qab cov txheej txheem ruaj khov, cov txiaj ntsig tuaj yeem nyob ze rau 100%.

(2) Cov khoom zoo yog qhov ruaj khov thiab rov ua tau zoo.Cov khoom lag luam tsis tshua muaj kev cuam tshuam los ntawm cov neeg ua haujlwm, thiab muaj qhov sib xws ntawm qhov sib xws txawm tias nws yog tib qho khoom siv lossis ntawm cov khoom siv. Cov ntsiab lus fiber ntau ntawm cov khoom tau muab tso rau hauv pwm raws li tus nqi teev ua ntej cov resin txhaj, thiab cov khoom muaj qhov sib piv ntawm cov resin, feem ntau 30% -45%, yog li cov uniformity thiab repeatability ntawm cov khoom ua tau zoo. zoo dua li cov khoom siv tes nteg cov txheej txheem. ntau, thiab tsawg dua.

(3) Kev tiv thaiv kev qaug zog yog txhim kho, uas tuaj yeem txo qhov hnyav ntawm cov qauv.Vim muaj cov ntsiab lus fiber ntau, tsis tshua muaj porosity thiab cov khoom ua tau zoo, tshwj xeeb tshaj yog kev txhim kho ntawm interlaminar lub zog, qaug zog tsis kam ntawm cov khoom tau zoo heev. Nyob rau hauv cov ntaub ntawv ntawm tib lub zog los yog kev nruj nruj, cov khoom tsim los ntawm lub tshuab nqus tsev induction tuaj yeem txo qhov hnyav ntawm cov qauv.

(4) Ib puag ncig tus phooj ywg.Lub tshuab nqus tsev infusion txheej txheem yog txheej txheem kaw pwm uas cov organics tsis zoo thiab cov pa phem nyob hauv lub hnab ntim khoom. Tsuas yog cov kab ntawm cov volatiles muaj nyob rau thaum lub tshuab nqus tsev twj tso kua mis (filterable) thiab cov resin chim qhib. VOC emissions tsis tshaj tus qauv ntawm 5PPm. Qhov no kuj tseem txhim kho qhov chaw ua haujlwm zoo rau cov neeg ua haujlwm, ua kom cov neeg ua haujlwm ruaj khov, thiab nthuav dav ntau yam khoom siv.

(5) Cov khoom ncaj ncees yog qhov zoo.Lub tshuab nqus tsev qhia cov txheej txheem tuaj yeem tsim cov ribs, cov qauv sandwich thiab lwm yam ntxig rau tib lub sijhawm, uas txhim kho kev ncaj ncees ntawm cov khoom, yog li cov khoom loj xws li kiv cua hoods, nkoj hulls thiab superstructures tuaj yeem tsim.

(6) Txo kev siv cov khoom siv raw thiab kev ua haujlwm.Nyob rau hauv tib layup, tus nqi ntawm resin yog txo los ntawm 30%. Tsawg pov tseg, resin poob tus nqi tsawg dua 5%. Kev ua haujlwm siab ua haujlwm, ntau dua 50% kev ua haujlwm txuag piv nrog cov txheej txheem ntawm tes. Tshwj xeeb tshaj yog nyob rau hauv molding ntawm loj thiab complex geometries ntawm cov qhaub cij thiab ntxiv dag zog rau cov qauv, cov khoom thiab kev ua hauj lwm kev txuag nyiaj yog txawm ntau ntau. Piv txwv li, hauv kev tsim cov rudders ntsug hauv kev lag luam aviation, tus nqi ntawm kev txo cov fasteners los ntawm 365 yog txo los ntawm 75% piv nrog rau cov txheej txheem ib txwm, qhov hnyav ntawm cov khoom tseem tsis hloov, thiab kev ua tau zoo dua.

(7) Cov khoom precision yog zoo.Qhov tseeb qhov tseeb (thickness) ntawm lub tshuab nqus tsev qhia cov txheej txheem cov khoom lag luam zoo dua li ntawm cov khoom siv tes. Nyob rau hauv tib lub layup, lub thickness ntawm cov khoom siv tshuab nqus tsev vacuum diffusion yog 2/3 ntawm cov khoom siv tes. Cov khoom thickness sib txawv yog hais txog ± 10%, thaum lub tes nteg txheej txheem feem ntau ± 20%. Lub flatness ntawm cov khoom nto yog zoo dua li ntawm tes nteg cov khoom. Sab hauv phab ntsa ntawm lub hood cov khoom ntawm lub tshuab nqus tsev cob qhia txheej txheem yog du, thiab qhov chaw ib txwm ua cov txheej txheem resin-nplua nuj, uas tsis tas yuav tsum tau ntxiv lub tsho tiv no. Txo kev ua haujlwm thiab cov khoom siv rau kev xuab zeb thiab pleev xim.

Ntawm chav kawm, tam sim no lub tshuab nqus tsev cob qhia txheej txheem kuj muaj qee yam tsis txaus:

(1) Cov txheej txheem npaj yuav siv sij hawm ntev thiab nyuaj dua.Kev teeb tsa kom zoo, kev tso chaw ntawm kev tshaj tawm kev sib txawv, cov raj xa dej, kev siv lub tshuab nqus tsev zoo, thiab lwm yam. Yog li ntawd, rau cov khoom me me, cov txheej txheem lub sij hawm ntev dua li cov txheej txheem ntawm tes.

(2) Tus nqi tsim khoom yog siab dua thiab ntau cov khoom pov tseg raug tsim tawm.Cov khoom siv xws li lub tshuab nqus tsev zaj duab xis, kev hloov pauv nruab nrab, tso tawm daim ntaub thiab lub raj xa dej yog tag nrho cov pov tseg, thiab ntau ntawm lawv tam sim no tuaj txawv teb chaws, yog li tus nqi tsim khoom yog siab dua li cov txheej txheem lay-up. Tab sis qhov loj ntawm cov khoom, qhov sib txawv me me. Nrog rau qhov chaw ntawm cov khoom siv pabcuam, qhov sib txawv ntawm tus nqi no tau txais me me thiab me. Kev tshawb fawb tam sim no ntawm cov ntaub ntawv pabcuam uas tuaj yeem siv tau ntau zaus yog kev txhim kho ntawm cov txheej txheem no.

(3) Cov txheej txheem tsim khoom muaj qee yam txaus ntshai.Tshwj xeeb tshaj yog rau cov khoom lag luam loj thiab nyuaj, ib zaug resin infusion tsis ua haujlwm, cov khoom lag luam yooj yim yuav tsum tau muab pov tseg.

Yog li ntawd, kev tshawb fawb ua ntej zoo dua, kev tswj xyuas cov txheej txheem nruj thiab cov kev kho kom zoo yuav tsum tau ua kom muaj kev vam meej ntawm cov txheej txheem.
