Steel fiber qhob: nta, GOST

Steel fiber yog npaj los txhim kho lub zoo cov yam ntxwv ntawm lub pob zeb ua tom qab nws attains nws tsim lub dag lub zog. Nws yog noteworthy uas siv fiber ntawm yooj yim heev, tab sis cov technology yog txawv nyob rau hauv hais tias nws yuav siv tau txawm los ntawm cov neeg uas tsis muaj ntau npaum li cas nyob rau hauv lub tshav pob ntawm kev tsim kho.

Qhov no cov ntaub ntawv uas ua lub luag hauj lwm ntawm lub hwj chim, thiab muab kev cia siab rau daim hlau. Hlau fiber ntaub ntawv ib tug unitary qauv nrog cov tshuaj thaum lub sij hawm nws, uas yuav tsum tau ua manually los yog mechanically. Nws tshwm sim ntau thiab stalefibrobetona, uas yog ib yam ntawm cov pob zeb uas valve zog khiav lag luam steel fibers. Lawv faib thoob plaws hauv lub ntim, thiab kev siv ntawm tej vaj tse lug tso cai rau kom tshem tawm los ntawm ib tug tej yam yog ib feem ntawm qhov cuab lub zog, thiab tej zaum kuj yuav kiag li cais hauv lub xub ntiag ntawm cov pa kav valve.

Efficiency nyob rau hauv kev siv ntawm steel fiber qhob Siv tiav los ntawm kev txo lub dag zog rau lub reinforcing ua hauj lwm thiab cov tshuaj thiab cov hlau khiav yuav txo tau. Txheej txheem ua hauj lwm tau muab thiab nws thiaj li ua kev reinforced loj yog tau, uas thiaj li muaj qhov complexity ntawm 27% thiab khaws rau kev tsim kho cov ntaub ntawv ntawm 1 m ³ lawm cov khoom.

Teb ntawm kev siv ntawm cov khoom

Steel fiber yuav siv tau:

• muaj floorings;
• Tshem tawm panels;
• pawg;
• hauv qab daus phab ntsa;
• screeds.

Ntawm lwm yam, cov ntaub ntawv uas siv nyob rau hauv lub lwm ntawm lub hauv paus, prefabricated tsev, txoj kev thiab kev pab txhawb nqa panels.

Lub ntsiab zoo ntawm steel fibers

Yog hais tias koj hloov ib tug Mesh nyob rau fiber, lub Screed thickness yog txo ho, thaum nws nqa peev xwm nyob twj ywm. Yog li stalefibrobetonnnye qauv muaj lub siab kuj yuav zoo li qub thiab dynamic loads. Tus tsim yuav siv sij hawm zoo ntawm speed kuj, puas kuj, kev co nce endurance thiab lub dag lub zog.

Thaum piv nrog cov tus tsoos steel fiber qhov cuab lub zog, tej zaum nws yuav muab sau tseg tias lub sij hawm siv nyob rau hauv lub installation ntawm li qub, yog txo. Qhov no yog vim lub fact tias lub steel fiber yog ntxiv rau hauv tus tov khoom los yog nyob rau hauv ib lub Hoobkas, thiab cov nws lub sij hawm tej zaum yuav nyob ntev li ntawm 5 mus rau 15 feeb. Kev co kuj vim lub fact tias cov loads yog faib tusyees thiab tsis txhob ua rau kom cov kev puas tsuaj ntawm qhob. Tab sis, yog hais tias koj muab tso rau lub reinforcing tuav thaum lub sij hawm lub pouring ntawm lub hauv paus, lawv yuav tsis cuam tshuam nrog rau cov tsim ntawm me me kab nrib pleb. Stalefibrobetona muaj ib tug nce kuj mus corrosion. Yog hais tias zoo li no tsis zoo los yuav raug rau qhov cuab lub zog, nws volume yuav ua rau kom ho nyob rau hauv lub tsim uas yuav ua rau kev puas tsuaj ntawm cov kev tiv thaiv txheej.

Ntsiab nta

Yog hais tias lub steel fiber yog ntxiv rau lub pob zeb ua thaum lub sij hawm lub creation ntawm ntau yam lug, lub tom kawg yuav muaj superior qualities ntawm dabtsi yog khoov zog thiab elongation, cov lwm yam, ua tau tiav ib tug txwv lub compressibility thiab siab tej yam muaj zog. Siv cov ntaub ntawv hais yuav txo tau shrinkage thiab nkag deformation. Cov khoom tau thermo-, te, thiab hluav taws-resistant, thiab kuj muaj ib tug high muaj peev xwm mus tiv thaiv puas.

kev yam ntxwv

Steel fiber rau ua vaj tse, cov duab uas yog nyob rau hauv tsab xov xwm yog ib tug ya ntawm hlau, qhov ntev ntawm uas yuav sib txawv los ntawm 0.5 mus 1.2 hli. Qhov ntev ntawm lub ntsiab mas nws txawv ntawm 25 mus rau 60 hli. Yog hais tias koj muaj ib tug los ze zog saib fiber, nws sau tseg hais tias nws cov xaus muaj ib tug tshwj xeeb configuration, nws txhawb nqa ib tug tuav khov nrog cov tshuaj.

Lub ntsiab yog tsim los ntawm cov uas tsis muaj hlau, uas belongs rau ib qho ntawm peb cov chav kawm ntawv zog. Nws tsiag ntawv los ntawm thawj 1,150 MPa, thaum lub sij hawm thib ob thiab thib peb muaj ib lub zog nyob rau hauv 1335 thiab 1550 MPa, ntsig txog. Kev siv ntawm steel fibers nyob rau hauv tej rooj plaub muaj zoo dua kev siv ntawm cov valve. Steel fiber rau ua vaj tse, tau ib m3 uas yog hais txog 25-50 kg, cov ntaub ntawv ib tug peb-dimensional qauv uas muaj peev xwm sawv ntawm tiv tensile kev nyuaj siab thiab eliminates microcracks qhia tawm. Cov yav tas yuav tsum tsim nyob rau hauv tus ntawm kev nyuaj siab thiab kev rau siab ya raws. Thaum kawg, steel fiber qhob yuav ua tsis tau qhov yuav tsum tau rau kev kho.

Cov nyiaj txiag zoo ntawm kev siv fiber

Steel fiber rau ua vaj tse, cov ndlwg ntawm uas tau raug hais saum toj no eliminates qhov kev ncua tshwm sim los ntawm cov installation ntawm cov pa fasteners. Yog li ntawd, mus rau qhov chaw ib daim phiaj rau hauv pem teb yog tsis tsim nyog yog hais tias tus ntau lawm yog nqa tawm nyob rau hauv loj qhov chaw ntawm qhob slabs. Thaum muab cov steel ntsiab yuav koom nrog tsawg heev tooj ntawm cov neeg ua thiab lub pob zeb ua kev tsim kho los ntawm yuav muaj ntau dua zoo, uas yog qhia nyob rau hauv lub fact tias Tensile thiab FLEXURAL zog nce los ntawm 2 lub sij hawm, thiab lub siab tshaj plaws tensile lim yog kho los ntawm 20 lub sij hawm. Tau siv lub fiber qauv txawm nyob rau hauv seismically tej cheeb tsam tej zaum yuav siv tau.

lub xeev cov qauv

Steel fiber rau ua vaj tse, uas zoo li GOST 3282-74 nruab nrab yog ib tug thauj tog rau nkoj khoom uas yog ua los ntawm stainless hlau. Qhov tseem ceeb tshaj parameter uas txiav txim seb tus raug cai - qhov no yog ib tug ib ntus kuj, uas pib los ntawm ib tug cim ntawm 900 N / hli ^2. Qhov no cov ntaub ntawv uas yog siv rau qhov siv thiab ua kua thiab Screed, reinforcing bases thiab rov qab Pavements. Qhov no fiber yog siv los thauj tog rau nkoj muaj khoom, tej chaw tiv thaiv, choj lug, runways thiab waterworks.

Nyob rau hauv cov lag luam tawm thiab ua tau raws li high-carbon steel fibers los ntawm hlau, uas thaum lub sij hawm siv thiab ua cov tooj dag coated sib tov. Nyob rau hauv cov ntaub ntawv no nws zoo li GOST 9389-75, thiab tensile lub zog ntawm cov khoom pib los ntawm 1200 N / hli ^2.

Cov yam ntxwv ntawm Dramix fibers

Yog hais tias koj xav nyob rau hauv steel fiber qhob Dramix, koj yuav tsum tau ua ntau me ntsis txog cov nws cov nta. Nws yog tsim los ntawm cov uas tsis muaj steel hlau, uas muab peb-dimensional qhov cuab lub zog. Qhov no fiber yog zoo li tus li ntawd nws adheres zoo mus rau lub pob zeb matrix. Siv cov khoom siv no yuav ua tau ib tug flooring nyob rau hauv ib lub lag luam, qhov siv thiab ua tubing ntau, qhob txau lawm thiab nyob rau hauv txhua rooj plaub thaum muaj ib tug xav los txhim kho qhov zoo cov yam ntxwv ntawm lub pob zeb ua.
