Khob fibers rau cov tsheb. Lub cev kho fiberglass

Cov ua chaw nyob rau hauv niaj hnub siv kis txoj kev puas muaj ntaub ntawv. Yuav ua li cas yog lub khob rau cov tsheb thiab vim li cas nws tau txais xws ntau? Cov teeb meem yog heev tseem ceeb niaj hnub no.

Niaj hnub nimno puas yog ib cov khoom uas muaj ib tug xov tooj ntawm Cheebtsam. Cias muab, nws tsis yog ib tug monolithic khoom, ib tug sib tov ntawm cov feem ntau ntau haiv neeg hais. Lub puas muaj ib tug matrix, uas yog ib lub hnab yas substrate lawm ua tus sau nrog ib tug loj tus naj npawb ntawm khaubncaws sab nraud povtseg ntawm cov ntaub ntawv uas.

Yuav ua li cas kom zoo dua puas iav rau cov tsheb nyob rau hauv pem hauv ntej ntawm tag nrho cov lwm yam niaj hnub ntaub ntawv? Ua ntej ntawm tag nrho cov, nws yog check heev thiab tawv, tab sis nyob rau tib lub sij hawm yog heev yooj yim thiab saj zawg zog cov ntaub ntawv uas. Fiberglass quantitatively thiab qualitatively superior rau txhua yam ntawm lub Cheebtsam. Yog hais tias composites siv nyob rau hauv lub tsheb lag luam, kev tsim kho yuav tau zoo heev txhua yam khoom, thiab yog nyob rau hauv txhua rooj plaub yuav tsis muaj kev cuam tshuam rau nws ceeb thawj.

Fiberglass thiab epoxy cob

By txuas lub saum toj no Cheebtsam yog tau ib tug ntawm qhov zoo tshaj plaws uas niaj hnub composites - fiberglass. Tam sim no tus nrov tshaj plaws thiab ntau cov ntaub ntawv uas yog siv nyob rau hauv cov automotive systems.

Tej lub sij hawm dhau los, feem ntau ntawm cov feem ntau ntau haiv neeg qhov chaw ua los ntawm hlau los yog yas. Tab sis, raws li kev xyaum qhia, qhov kev kuaj ntawd rau lub sij hawm thiab lub critics yuav tsis tiv nuj nqis rau ib tug los yog rau lwm cov khoom. Tej khoom ua los ntawm cov hlau, muaj ib tug es loj nyhav thiab feem ntau tawm ntawm kev txiav txim vim qhov tshwm sim ntawm xeb dab, tab sis lub fiberglass cev tsim nws tus kheej tsuas yog nyob rau qhov zoo sab, txawm nrog heev siv yog kiag li tshem tawm xeb. Raws li rau cov yas, nws yog, nyob rau hauv tsis tooj, ib yam nkaus thiab nkig, lub cev tsis kho thiab yuav tsis tau withstand hnyav loads, tab sis yog yus muaj los ntawm cov uas tsis muaj ceeb thawj. Qhib ntawm fiberglass tag nrho dramatically pauv.

Lub sab hauv qauv ntawm fiberglass

Niaj hnub nimno iav fiber khoom yog ib tug iav fiber epoxy, uas yog raws li muab tub lim ntaub kho cob. Lub thav duab cov ntaub ntawv uas tsim raws nraim fiber yog tseem lub luag hauj lwm kom zoo theem yam khoom ua los ntawm fiberglass. Lub ntsiab txheej xwm ntawm lub substance yog lub degree ntawm kam thaum dabtsi yog khoov los yog so, thiab lub dag lub zog lawm.

Epoxy cob yog ib tug phau ntawv tivthaiv. Nws txiav txim qhov kev kawm cov yam ntxwv ntawm fiberglass, piv txwv li, corrosion kuj, thermal conductivity, elasticity thiab dielectric zog. Fiberglass thiab epoxy cob rau tsim ib tug tshwj xeeb cov qauv uas tso cai rau kom muaj ntau yam zoo tshaj tag nrho cov lwm yam ntaub ntawv.

epoxy iav fiber ntau lawm technology

Muaj ntau lawm ntawm cov iav fiber tam yas yog ua yog nyob rau hauv ib los yog nyob rau hauv ob ua sawv. Nyob rau hauv nqa tawm hauv tus txheej txheem yog twv iav ncaj qha los ntawm ib tug iav molten loj. Yog hais tias zus tau tej cov khoom yog nqa tawm nyob rau hauv ob ua sawv, thawj ua me me qhov chaw ntawm lub fritted lub khob los yog cov thawj iav hlaws dai. Lawv melted, mam li ntxiv rau lub resulting fiberglass cob. Nrog rau qhov no bumper fiberglass technology puv zog npaum li cas tshaj yas.

cov ntaub ntawv uas cov kev pab cuam

Fiberglass muaj ib tug ntau ntawm cov tseem ceeb zoo dua tag nrho lwm yam uas zoo sib xws cov ntaub ntawv. Cia peb xav txog lawv:

• ya raws kuj;
• lub teeb yuag;
• Yooj yim rau nruab;
• kuj rau tej teebmeem;
• nqi (.. xaiv fiberglass, uas nws nqi - txog 100 rubles ib 1 square meter, koj zoo heev txog cov nqi ntawm kho tsheb) ;
• ib theem siab ntawm thermal rwb thaiv tsev;
• ntev kev pab cuam lub neej - mus txog rau 50 xyoo;
• tsawg degree ntawm thermal conductivity;
• ceev installation.

Fiberglass yog dav siv nyob rau hauv ntau yam teb. Txawm li cas los, lub ntsiab siv ntawm no cov ntaub ntawv uas yog nyob rau hauv tsheb daim ntaub ntawv. Ntawm no los ntawm nws ua ib lub cev, bumpers thiab lwm qhov chaw.

kho technology

Khob fibers rau cov tsheb - lub feem ntau haum cov ntaub ntawv uas, tshwj xeeb tshaj yog yog hais tias nws yog tsim nyog los kho lub cev. No ua hauj lwm, cov tseem ceeb tshaj plaws - mus soj ntsuam cov neeg ntawm lub tshuab.

1. Lub cev yuav tsum tau ntxuav cov xim muaj hlau, rau qhov no koj yuav siv ib tug tshwj xeeb stripper.
2. Tom qab ntawd, txiav ib daim ntawm cov iav, qhov luaj li cas ntawm cov uas yuav tsum yoog mus rau lub puas cheeb tsam.
3. Cov kauj ruam tom ntej yuav ua tau qhov kev npaj ntawm epoxy resins. Nws yog tsim nyog los tos ib tug tshwj xeeb lub thawv, ntxiv hardener thiab sib tov zoo.
4. Lub puas qhov chaw nyob rau hauv lub cev kho cob.
5. Tom qab ntawd glued fiberglass thiab coated dua nrog cob. Qhov no tus txheej txheem yog ntev heev, raws li koj yuav tsum ua tib zoo lis tag nrho saum npoo.
6. Qhov kawg kov - xov impregnation cob nrog ib tug menyuam chaotic taw.

fiberglass txuj

Muaj ntau tsav tsheb xav kom xyaum ua tej yam nrog fiberglass, ua los ntawm nws tshiab ntsiab lus. Txawm li cas los, nws yog heev yooj yim rau daim ntawv. Nws yog pom zoo kom siv ib lub khob fiber mats. Qhov no txoj kev tsis yuav tsum tau loj kev nqis peev. Fiberglass (nqi, dua, - los ntawm 100 rubles) yog feem ntau kho nrog gelcoat, cov nqi ntawm uas tsis pub tshaj 400 rubles. ib kilogram. Nws yog thov nrog ib tug txhuam los yog tshuaj tsuag rab phom, thiab ces rau kev kawm dav hlau.

Yog vim li cas lub khob?

Tam sim no, feem ntau manufacturers muaj tau txais kev pab iav rau cov tsheb ntawm ntau hom nyob rau hauv cov nqe lus ntawm lawv cov functionality. Nyob rau hnub no txoj kev siv kev ua lag luam, qhov no cov ntaub ntawv uas yog los sib tw nrog lwm hom, uas txog thaum tsis ntev los no nrees nyob rau hauv lub ua txoj hauj lwm, piv txwv li, lub khob, pob zeb ua, co, thiab lawv alloys, ceramics thiab ntoo. Raws li nws cov ntsiab yam ntxwv thiab cov khoom ntawm tej yam ntawm cov ntaub ntawv no yog tsis muaj peev xwm los sib tw nrog lub khob fibers.

Los ntawm nws kev siv ntawm lub tsheb qhov chaw yuav siab zog: yog hais tias lub tshuab yog lossi siv nyob rau hauv lub caij ntuj no, nws qhov chaw no yog ua los ntawm fiberglass, xyuam xim mas qhov sib txawv climatic tej yam kev mob. Nws yog ib nqi ntxiv hais tias cov khoom no, zoo li stainless steel, nws tsis yog amenable mus rau ib lwj los yog corrosion. Nws yog ua tsaug rau nws invention ntawm ib tug tshwj xeeb lub sij hawm los ntev lub neej ntawm tsheb rau ob peb xyoo lawm, txij thaum cov qhov chaw rau ib ntev lub sij hawm ntawm lub sij hawm, tsis txhob yuav tsum tau tej anti-xeb kev kho mob.
