Modified Yas, Ntev Iav Fiber PP Ntev hauv kawg yog ntev npaum li cas?
Tej zaum koj nyeem ntau xov xwm thiab xov xwm ntawm tsheb tsheb sib tw, ntev fiberglass PP thiab nylon yellows, thiab uas tau tsim cov khoom tshiab fiberglass. Qhov tseeb yog qhov tseem ceeb "vim li cas? Yuav siv qhov twg?" Yuav kom tsis muaj leej twg hais txog yam tseem ceeb tshaj plaws - yuav ua li cas npaj cov ntaub ntawv no? Xiao Bian nyeem tsuas yog xav hais tias "lub cev tau hollowed tawm", cov yas hauv lub tsheb, tab sis tseem yuav ua li cas siv lub hnub los tham txog?
Li ntawd, Xiao Bian tham nrog koj hnub no thiab seb yuav ua kom ntev ntev ntawm iav fiber hauv lub qauv matrix los ntawm cov cuab yeej thiab kev siv tshuab? Yuav ua li cas thov, rau dab tsi khoom, yog tom qab lo lus. Mus qiv tag nrho cov neeg ua yeeb yam nyiam ib lo lus, uas yog, "rov qab mus rau qhov qub, tsis hnov qab pib lub siab!"
Ua ntej, qhov zoo tshaj fiber ntau iav substrate ntev
Cov iav fiber ntau hauv daim duab matrix ntev yog luv heev, tsuas yog lub luag haujlwm ntawm cov tub luam, tsis tuaj yeem txhim kho lub luag haujlwm ntawm (xws li ob peb duas las ntawm CaCO3 qhov kev cuam tshuam zoo li qub, poob ntawm koj); ntev ntev, txawm hais tias qhov kev kho kom zoo Tshaj, tiam sis cuam tshuam rau cov dispersion ntawm iav fiber hauv lub qauv matrix, tsim processability thiab cov khoom ua tau zoo.
Cov nyhuv ntawm Fiber Retention Ntev rau Kev Ua Tau hauv Cov Ncej
Yog li, nws feem ntau ntseeg hais tias qhov zoo tagnrho ntev ntawm iav fiber ntau hauv matrix thermoplastic yuav tsum yog 5 npaug nws qhov tseem ceeb ntev. Qhov tseem ceeb ntev yog qhov tsawg kawg nkaus uas tsim nyog rau iav fiber nyob rau hauv kev nyuab siab nyob rau hauv ib lub cev diam ntawm lub fiber reinforced thermoplastic kom ncav cuag tus nqi ntawm nws cov kev nyuaj siab ntawm so. Nruab nrab yog tias koj mus rau lub khw yuav ris, cov ris ntev ntev tsis zoo rau pob taws, tiam sis loj hlob ob peb centimeters, kom tiv thaiv kom txhob tsaus muag rau hauv lub ris yog lub tswv yim. Raws li cov lus hais tias "tsis muaj ntau tshaj li qhov tsis tau ua ntej."
Ntev ntev / luv iav fiber ntau hloov PP kev sib piv
Vim hais tias nyob rau hauv lub khob fiber reinforced yas, fiberglass ntev tsuas ncav cuag ib yam ntev mus rau kev hloov siab, ua si lub luag hauj lwm kom txhawb nqa cov khoom, txwv tsis pub nws yog High School-qib CaCO3. Tab sis nws tsis yog tib yam li kev ntaus yeeb yam tshiab "ib ntu ntev, ib nti muaj zog", tab sis nws muaj qhov ntev tshaj plaws. Tsis tas li ntawd, txawm tias qhov pom kev pom ntev lawm, nws tsis tuaj yeem 100% lav tias qhov ntev ntawm iav fiber ntau nyob hauv qhov khoom yog qhov tseem ceeb vim tias cov khoom siv thiab cov txheej txheem muaj kev zoo rau lub sijhawm kawg ntawm cov iav fiber . Piv txwv, koj lub ris ntsuav. Yog li, tom qab ntawd Xiaobian tham txog koj yuav ua li cas kom paub tseeb tias ntev npaum li cas ntawm cov khoom siv fiberglass rau khoom siv thiab tshuab.
Qhov thib ob, qhov zoo tshaj plaws uas cuam tshuam qhov ntev ntawm iav fiber ntau hauv plastics
1, khoom siv
(1) kev sib tsoo cov cuab yeej thiab cov khoom haum
Cov hom phiaj ntawm twin-screw configuration tsim thiab chim configuration rau kev npaj cov iav fiber ntau yog: (1) los tiv thaiv cov duab matrix ntawm degradation thiab ua rau cov iav fiber uniformly dispersed hauv matrix re; (2) los xyuas kom meej tias txhua lub fib fais yog qhov kawg ntawm qhov Polymer Degree of wetting; ③ cov nqaij ntuag tau mus rau qhov ntev tshaj plaws, los xyuas kom meej tias cov dej sib xyaw kom siab tau zoo tshaj plaws cov nyhuv; ④ extrusion txheej txheem ntawm cov neeg tsis tuaj yeem ua pa yuav raug thawb.
⑴ khob fiber ntau ntxiv rau cov ntaub ciav hlau: iav fiber ntau ntxiv rau lub zawj yuav tsum tau siv rau cov hmoov lead loj, lub polymer uas muaj cov ntsia thawv kom ntws tawm qhov chaw txaus kom haum lub khob fiber ntau. Tsis tas li ntawd, kom tsis txhob muaj qhov chaw nres nkoj raug thaiv los ntawm lub polymer, lub iav fiber ntau yog nkag nrog ib qho xov thawj, thiab cov iav ntev tuaj yeem nkag nrog tsawg kawg yog ib tug khub ntawm cov pob txha caj dab.
⑵ khob txiv hmab txiv ntoo txiav tawm thiab tawm tsam:
① iav fais fab hauv qab ntws ntawm tus qauv txhuam cov qauv tsim yuav tsum muaj qhov hloov ntawm qhov ntev ntawm iav fiber ntau thiab homogenization. Ntev iav ntev yog qhov kawg. Tom qab lub hau ntswj ntxiv, nws yuav tsum tau txiav mus rau hauv ib qhov ntev thiab sib tov zoo nrog lub yaj. Cov nplaum yuav tsum yog tsim los ntawm cov khoom faib thiab muab cov khoom qub los sis cov pob txha uas tov nrog cov ntaub qhwv tov.
② Luv khob iav, tsuas yog los ntawm polymer yaj fiber ntau soaked thiab dispersed, ces tus nplaum ntog yuav muaj ib lub tais nyias nyias ntawm cov khob ntawm lub hauv paus tawg los yog grooved nyob rau hauv qhov muab xauv rau ntawm cov xov thawj los yog cov ntawv phaj toothed.
(3) high viscosity polymer los yog cov iav siab (> 40%) cov khoom sib txhuam tsis tshua muaj viscosity polymer lossis iav fiber cov ntsiab lus ntawm qhov kev sib tsoo cov cuab yeej muab rau kev sib txeeb kom paub meej tias cov iav tsis tuaj yeem tawg.
(2) qhov chaw seem cua
Vim tias qee qhov iav yog pretreated, xws li ntev fiberglass twisting fibers yog kho nrog ib tug paraffin ua liaj ua teb emulsifying impregnant, thiab untwisted fibers yog kho nrog ib tug toughening tus neeg sawv cev. Nyob rau ntawm tej lub ntsuas kub, tom qab cov iav fiber yog yaj-sib xyaw, tus neeg sawv cev thiab tus neeg txhawb zog rau hauv cov iav fiber ua qhov khoom faib tawm tom qab raug rau hauv kev kub siab thaum lub sij hawm extrusion txheej txheem, thiab cov cua tso tawm yuav tsum tau muab pov tseg kom raug cais tawm. Txoj hlua yuav tsum muaj nyob rau ntawm qhov fiberglass inlet, ntws sab hauv ntawm qhov chaw nres tsheb sab nraud ntawm qhov chaw nres tsheb sab nraud, qhov kev sib tsoo qhov yuav tsum tau txhawm rau tiv thaiv lub tshuab nqus tsev hauv qhov kev txiav txim ntawm cov khoom raug rho tawm, xws li rov qab xov los yog rov qab kneading blocks .
(3) Tshooj kawg ntawm lub hau ntswj (homogenization thiab tsim qhov siab)
Yuav kom rho tawm qhov sib tov rau hauv qhov tuag, ib qho khoom me me rau pem hauv ntej pub xov yuav tsum raug siv los tsim kom muaj lub siab tawg. Nyob rau hauv qhov chaw nres nkoj thiab qhov kawg ntawm lub hau ntswj, thiab qee zaus los muab cov ntawv phaj toothed thawj, lub homogenization fiber ntau, kom tsis muaj cov xim fiberglass.
2 Tawm tswv yim
(1) Cov iav fiber ntau ntxiv
Ntev iav fiber ntau thiab iav fiber ntau los koom siv ntau txoj kev.
① luv iav fiber ntsuas cov khoom feem ntau tuaj koom, tab sis thaum cov iav fiber ntau ntev dua 6 hli, koj siv tau cov khoom ntsuas vibrating, lub pob zeb ntawm cov tshuaj polymer thiab iav ua ke, los yog nws yuav ua rau cov fiber ntau thiab kev sib cais. Yuav kom nce lub qhov tso zis, sab pub ntxiv yuav ntxiv los ntawm sab kev pub mis.
② ntev fiber ntau yooj yim mus koom, tsis tas yuav tshwj xeeb pub khoom, ntev li ntev ntawm cov iav dai fiber ntau rau hauv qhov chaw nres nkoj ntxaib pub mis.
(2) Qhov chaw ntawm lub khob fiber ntau ntxiv
Raws li ib txwm muaj, lub polymer ntxiv rau hauv qhov chaw pub thawj zaug (main) pub mis, yuav tsum yaj, thiab mam li ntxiv cov khob cij pub mis rau hauv qab, uas siv cov khoom rov qab. Vim hais tias ntawm kev rov qab noj, khob fiber ntau ntxiv rau melted polymer, yaj thiab fiber ntau sib tov, fiber ntau qhwv, ua si lub luag haujlwm hauv kev tiv thaiv lubrication, txo fiber ntau thiab ntau ntau txoj kev ntxaws ntxoo rau txoj kev fiberglass Dispersion thiab faib nyob rau hauv lub yaj.
Albania xaus lus
Cov teeb meem uas tau teev tseg los ntawm Xiaobian tsuas yog qee yam tseem ceeb tshaj. Nyob rau hauv cov txheej txheem ntawm iav fiber ntau hloov kho, tshwj xeeb tshaj yog ntev iav fiber ntau hloov plastics, muaj ntau ntau yam cuam tshuam cov zoo ntev ntawm iav fiber ntau. Yog li ntawd, thaum kawg, nws nce mus txog qhov khoom ua tau zoo noj mov, seb qhov txheej txheem, khoom siv, thiab daim ntawv qhia yog tsim nyog. Technology yeej ib txwm tho kev, tab sis nws lom zem ua ib feem thiab kev hlub. Xiaobian muaj peev xwm thiab paub tsawg, txais tos rau txhua tus tub txawg kev sib tham Xiaobian, thov tau kawm ntawv rau peb!
Cov khoom los ntawm phau ntawv los ntawm Yang Mingshan, kho los ntawm Alban pab pawg. Tsim los qhia kev siv tshuab, kev kawm paub, Albanian kws phais neeg!
