Nyob rau hauv kev tsim kho, raws li nyob rau hauv lwm yam lag luam yog nce resorting rau kev siv nyob rau hauv qhuav ntawm khoom muag thiab kev pab cuam ntawm lub tshuab tseeb thiab innovation. Fiberglass qhov cuab lub zog - ib qho piv txwv ntawm xws li ib lwm txoj kev daws teeb meem. Nws sai sai txaus los hloov tsoos hlau qhov chaw, ua ntej ntawm lawv economic thiab kev tsis. Nyob rau hauv no tsab xov xwm koj yuav kawm dab tsi hauv lub fiberglass qhov cuab lub zog. Tus yam ntxwv ntawm cov khoom no yog hais nyob rau hauv kev sib piv nrog rau lwm tus neeg.

Fiberglass qhov cuab lub zog - yog dab tsi?

Reinforcing txhais tau tias, los yog uas tsis yog-nws yog xim hlau qhov cuab lub zog fiberglass yog ib tug pas nrig nrog ib tug ribbed nto ntawm cov iav fibers. Spiraleoobrazen nws profile, thiab txoj kab uas hla xws li ntawm 4 mus rau 18 hli. haum ntev yuav ncav cuag 12 meters. Tej zaum, nws tshwm sim nyob rau hauv daim ntawv ntawm cov coils, lub lub cheeb ntawm lub tsev cov ntaub ntawv uas yog 10 hli.

Sia mus thoob ntiajteb Fiberglass rebar, daim ntawv thov uas yog cia li zoo, raws li peb tau, hu ua polymeric khoom. Qhov no tas mus li fiber qhov cuab lub zog. Nyob rau hauv Russia, nce nyob acronym AKC.

Yuav ua li cas yog fiberglass qhov cuab lub zog?

AKC lub cev lub cev yog tsim los ntawm cov ob peb qhov chaw:

1. Lub ntsiab lub cev. Nws yog ua los ntawm thaum uas tig mus fibers uas yog kev cob cog rua rau lub polymer cob. Lub ntsiab lub cev muab qhov cuab lub zog lub dag lub zog.

2. Cov txheej txheej - yog ib tug fibrous lub cev. Nws yog lub qhov txhab nyob rau hauv ib tug kauv nyob ib ncig ntawm lub pob tw ntawm lub AKC. Nws tshwm sim raws li cov xuab zeb Txau los yog bidirectional winding.

Muaj ntau variations ntawm fiberglass, nws tag nrho cov nyob rau hauv lub tswv yim ntawm lub chaw tsim tshuaj paus thiab lub feasibility ntawm know-yuav ua li cas. Cov muag khoom yuav pom armature tub ntxhais chim uas yog nyob rau hauv daim ntawv ntawm cov pa roj carbon fiber pigtails.

Ntsiab zog

Yuav kom txiav txim seb lub thaj chaw ntawm fiberglass, nws twb ua ib tug ntau ntawm kev tshawb fawb thiab kev soj ntsuam. Cov kev tshwm sim tau yog piav raws li cov AKC siab zog thiab check khoom rau kev tsim kho, uas muaj ntau yam zoo tshaj lwm yam ntaub ntawv:

• tsawg qhov ceeb thawj (fiberglass lighter hlau fittings 9 sij hawm);
• kuj mus corrosion nyob rau acidic tej kev kawm thiab corrosive chloride (10 lub sij hawm superior thaj chaw ntawm lub steel qhov cuab lub zog);
• tsawg thermal conductivity;
• efficiency (nws yog ntau muaj txiaj ntsim mus nqa, thiab cov kev hloov yog nqa tawm tsawg zaus);
• magnitoinertost;
• xov tooj cua transparency;
• Fittings yog ib tug dielectric.

Fiberglass qhov cuab lub zog: shortcomings

Nyob rau hauv tas li ntawd mus rau lub undoubted merits ntawm kev ua si, ua tsaug rau uas nws tau tau zoo kawg muaj koob meej ntawm kev tsim kho tuam txhab uas muag thiab zoo tib yam cov pej xeem, nws muaj nws cov drawbacks. Ntawm cov hoob kawm, tseem ceeb heev yuav tau hu rau lawv nyuaj heev. Txawm li cas los, nws yuav tsum tau borne nyob rau hauv lub siab thiab tsis zoo cov yam ntxwv ntawm cov khoom, uas tej zaum yuav cuam tshuam rau cov txheej txheem ntawm kev tsim kho.

Yog li, cov disadvantages:

• tsawg modulus ntawm elasticity;
• tsis txaus tshav kub tsis kam qhia;
• Lwm yam.

Vim cov uas tsis muaj elasticity ntawm kev ua si nws yog ib qho yooj yim khoov. Rau lub chaw ua khoom ntawm lub hauv paus thiab tus khiav nws tsis yog ib tug loj drawback. Tab sis nyob rau hauv cov ntaub ntawv nrog lub zus tau tej cov slabs tau ua ntxiv suav, noj mus rau hauv tus account qhov no feature ntawm cov valve.

Tsis txaus tshav kub kuj - ib tug loj heev drawback ntawm kev ua si. Lub fact tias cov iav nws tus kheej yog thaum tshav kub kub-resistant, tsis yog dab tsi. Yas link muaj peev xwm tsis mas siab kub, tab sis yog hais txog cov pab pawg neeg armature self-extinguishing cov ntaub ntawv. Qhov no feature yog zoo mus rau ib tug kub ntawm 2000 degrees centigrade, whereupon ACN loses nws lub zog. Yog li ntawd, cov kev siv ntawm fiberglass nrog qhob yog txwv tsis pub. Tej qub yuav siv tau xwb nyob rau hauv cov cheeb tsam ntawm lub tsev, uas tag tshem tawm qhov kub thiab txias dauv. Txawm li cas los, cov kev cai no yog yuav luag ib txwm nqa tawm nyob rau hauv cov pa thaj thiab ib co muaj vaj tse.

Fiberglass rebar, qhov twg lub shortcomings uas muaj npe saum toj no, muaj ib tug xov tooj ntawm kev tsis zoo. Thaum lub sij hawm, lub dag lub zog ntawm nws puas lawm, thiab nyob rau hauv tus ntawm alkaline tebchaw cov tshuaj tiv thaiv tus nqi yog nce los ntawm ob peb lub sij hawm. Txawm li cas los, niaj hnub technologies cia kom tiv nrog no drawback. Muaj pes tsawg leeg ntawm lub AKC ntxiv tsawg lub ntiaj teb co uas ua rau fiberglass tsawg sensitive.

Ib txhia kws txawj hais qhov tseeb hais tias xws li yuav tsis ua siab ntev welding. Yog li ntawd, muaj ntau yam xav kom "sawv" ntawm fiberglass nplawm.

fiberglass Manufacturing

Peb feem ntau siv fiberglass qhov cuab lub zog nyob rau hauv tsev, rau piv txwv, pouring lub hauv paus thiab lwm tus neeg. Qhuav ntawm kev ua si tsis muaj yuav tsum tau nyob rau hauv-line. Muaj ntau nws pib kho khw, kev soj ntsuam txog nrog lub tsheb nyob, tso cov ntaub ntawv uas nyob rau hauv ib tug txawv configuration.

Tab sis nyob rau hauv cov ntaub ntawv no peb yuav sib tham txog me-scale lawm. AKC muab tso rau hauv kwj tsuas loj industrial qhauj.

Muaj ntau ntau yooj yim txoj kev ntawm kev siv thiab ua:

• Broaching;
• wrapping;
• phau ntawv txoj kev.

Tus thawj txoj kev yog siv rau manufacturing ntau yam profiles. Nyob rau hauv lub khiav ntawm ib tug tas mus kab ntawm cov iav fiber yog unwound. Feem ntau cov feem ntau deployed nrog bobbins thaum uas tig mus kab teeb ntawm cov ntaub ntawv uas yog tsis cov ua ke. Kws txawj hu no roving ntau lawm. Ua ntej yuav bobbin tuaj mus rau hauv kev txiav txim, fiberglass lubricated cob uas muaj ib yam khoom uas rau nws polymerization sov siab. Maj mam, cov khoom yuav tawv, tab sis qhov no cov nyhuv yog tiav vim cov tshuaj cov tshuaj tiv thaiv tshwm sim. Ces tus iav kis tau los ntawm cov ntxaij lim dej uas tso rau hauv lub dhau heev lawm cov ntaub ntawv uas los ntawm lub cob, thiab acquires ACN li ib txwm cylindrical zoo. Thaum lub valve yog tsis solidified, nws spirally txhab ib tug tshwj xeeb sam xauv nees. Hais tias yog, nws muab lub dag lub zog thaum nyob rau hauv kev sib cuag nrog qhob. Vim hais tias ntawm cov cuab yeej no yog nce siv fiberglass rebar rau lub hauv paus. Xyuas uas tawm hauv lub builders, feem ntau zoo.

Tom qab tag nrho cov manipulations ACN kis tau los ntawm ib qhov cub nyob qhov twg nws yog thaum muaj kev kub kub hardens. Tom ntej no cov tiav lawm qhov cuab lub zog yog txiav mus rau hauv daim ntawm qhov kev kawm ntev (hu ua whipping). Tej zaum ACN yog lub qhov txhab mus rau ib tug bobbin, tab sis qhov no yog tsuas tau yog hais tias nws muaj ib tug me me txoj kab uas hla. Tuab lashes tsis yooj yim sua twist. Qhov no fiberglass rebar, kev siv ntawm cov uas yog heev, yog ua nyob rau hauv loj qhov ntau thaum nws los txog rau loj-scale lawm.

winding txoj kev ua feem ntau ntawm fiberglass kav. Lawv yog ua los nyob rau hauv tib lub ntsiab cai raws li cov nplawm. Nyob rau hauv ib tug tshwj xeeb tshuab yog lub qhov txhab iav fibers impregnated nrog cob. Winding ntaus ntawv, vim nws kev sib hloov, nws tso cai rau kom muab tau ib tug cylindrical nto. Tom ntej no lub khob kis tau los ntawm ib tug kub qhov cub thiab txiav mus rau hauv lub raj ntawm txhais qhov ntev.

Cov phau ntawv txoj kev yog feem ntau siv nyob rau hauv me me-scale lawm. Fiberglass qhov cuab lub zog, uas tsis zoo tsis heev cuam tshuam zaum kawg tshwm sim tso cai rau kom tau txais ib tug khoom tsheb lub cev, bumpers thiab cov zoo li. D. Wizards muab ib tug tuag precoated zoo nkauj thiab kev tiv thaiv txheej. Feem ntau qhov no yog ua li cas siv cov tshuaj tsuag, uas tso cai rau rau ib yam nyhuv. Tom qab hais tias, lub matrix iav khoom yog pw, uas yog txiav tawm nyob rau hauv ua ntej ntawm yam loj. Khob fiber los yog iav lev yog impregnated nrog ib tug polymeric cob sib tov. Nws yog qhov zoo tshaj plaws los mus siv ib tug txhuam hniav. Nrog ib tug menyuam ntawm cov ntaub ntawv uas seem cua yog squeezed, kom tsis txhob voids nyob rau hauv lub fiber. Thaum cov ntaub so ntswg tau hardened, nws yog txiav, tsim rau hauv lub Desired zoo, drilled qhov nyob rau hauv nws, thiab hais txog. N. Ces koj yuav siv lub matrix dua.
