SMC Resin manhole npog

(1) Lub zog siab: siv cov khoom siv hluavtaws polymer
(2) Cov tsos zoo nkauj: Cov qauv saum npoo ntawm lub iav steel manhole npog yog tsim zoo heev, uas tuaj yeem ua rau ntau yam qauv thiab xim kom zoo nkauj hauv nroog ib puag ncig, uas yog ob qho tib si zoo nkauj thiab ruaj khov.
(3) Lub teeb yuag: Qhov hnyav ntawm cov khoom tsuas yog kwv yees li ib feem peb ntawm cov hlau cam khwb cia, uas yooj yim rau kev thauj mus los, kev teeb tsa thiab kho, thiab txo qis kev siv zog ntau.
(4) Kev tiv thaiv tub sab: Cov khoom siv hluavtaws tsis muaj nqi rov ua dua thiab yog ib txwm tiv thaiv tub sab;thiab yog nruab nrog lub xauv qauv
(5) Muaj zog huab cua tsis kam: Cov khoom siv cov khoom hnyav molecular nrog cov hnyav molecular loj thiab muaj zog tshuaj lom neeg ruaj khov raws li cov khoom siv raw.Los ntawm cov qauv kev tshawb fawb, kev siv thev naus laus zis, thiab cov cuab yeej zoo tshaj plaws, cov khoom siv tuaj yeem siv ib txwm ntawm -40 ℃ -90 ℃ .
(6) High precision: Vim tias cov khoom yog molded ntawm qhov kub thiab txias, qhov sib txawv ntawm lub hau thiab lub rooj yog me me, uas kov yeej cov teeb meem ntawm "khiav, dhia, thiab ringing" ntawm cam khwb cia hlau thiab cement manhole npog, thiab txhim kho txoj kev tsheb. muaj peev xwm thiab tsav tsheb yooj yim.
(7) Corrosion kuj.Nws muaj cov kua qaub thiab alkali tsis kam thiab corrosion kuj, thiab qhov kev tiv thaiv kev laus nce mus txog qib peb, thiab kev pab cuam lub neej ntev dua.

Kev soj ntsuam manhole npog yog compounded los ntawm kev siv polymer raws li cov khoom siv matrix, ntxiv cov ntaub ntawv ntxiv, muab tub lim, thiab lwm yam, los ntawm ib qho txheej txheem.Tus txheej txheem tshiab hauv tebchaws tau tsa qhov kev xav tau ntawm lub qhov npog manhole thiab ua raws li kev lees paub thoob ntiaj teb EN124 tus qauv.
Nyob rau hauv qhov tseeb, lub resin manhole npog (tseem hu ua polymer iav fiber reinforced yas manhole cover / composite material manhole cover) yog ib hom iav fiber ntau thiab nws cov khoom (iav ntaub, daim kab xev, xav, xov paj, thiab lwm yam) raws li cov ntaub ntawv txhawb zog, thiab hluavtaws cob raws li cov khoom siv matrix.Ib hom tshiab ntawm manhole npog cov khoom tsim los ntawm unsaturated polyester resin, fillers, initiators, thickeners, tsawg shrinkage additives, zaj duab xis pwm tus neeg saib xyuas, pigments thiab reinforcing cov ntaub ntawv, thiab ces molded nyob rau hauv high kub.

Cov ntaub ntawv tseem ceeb ntxiv yog cov khoom siv fiber ntau (cov ntaub iav, ntaub nplaum, muaj lub siab, xov paj, thiab lwm yam), uas yog cov cim me me, lub zog tshwj xeeb thiab cov qauv tshwj xeeb.Piv txwv li, carbon fiber thiab epoxy resin composite cov ntaub ntawv muaj lub zog tshwj xeeb thiab tshwj xeeb modulus ob peb zaug loj dua cov hlau thiab txhuas alloys.Lawv kuj muaj kev ruaj ntseg zoo heev, kev sib txhuam txo, hnav tsis kam, nws tus kheej lubrication, kub tsis kam, qaug zog tiv thaiv, thiab Creep, txo suab nrov, hluav taws xob rwb thaiv tsev thiab lwm yam khoom.Qhov sib xyaw ntawm graphite fiber ntau thiab cov resin tuaj yeem tau txais cov khoom siv uas nws qhov nthuav dav coefficient yuav luag sib npaug rau xoom.Lwm qhov tshwj xeeb ntawm cov khoom siv fiber ntau yog anisotropy, yog li cov txheej txheem fiber ntau tuaj yeem tsim tau raws li qhov xav tau ntawm lub zog sib txawv ntawm qhov sib txawv.Cov khoom siv aluminium-based composite ntxiv nrog carbon fiber thiab silicon carbide fiber tseem tuaj yeem tuav lub zog txaus thiab cov qauv ntawm 500 ° C.
Resin manhole npog siv rau ntawm txoj kev muaj cov yam ntxwv ntawm rwb thaiv tsev, tsis muaj suab nrov, tsis muaj nqi rov qab thiab ntuj tiv thaiv tub sab.Nws yog irreplaceable rau cam khwb cia hlau manhole npog.
Resin manhole npog yog tsim los ntawm cov txheej txheem molding tshwj xeeb, uas ua rau lub nroog zoo li ib qho tshiab.Kev pabcuam lub neej yog qhov pib 20-50 xyoo.Cov resin composite manhole npog molded los ntawm qhov kub thiab txias muaj lub teeb yuag, siab zog, zoo heev qaug zog, thiab kev nyab xeeb puas., yooj yim molding, tsis tshua muaj suab nrov, zoo tshuaj corrosion kuj, zoo acid thiab alkali tsis kam thiab zoo nkauj tsos, thiab lwm yam, thiab cov pa phem nyob rau hauv cov dej khib nyiab yog ntxiv txo.

Thaum txhim kho ib tug composite manhole npog, ua raws li nram no plaub kauj ruam:

1. Ua ntej installation, lub hauv paus ntawm lub manhole npog yuav tsum zoo huv si thiab ruaj, thiab lub puab txoj kab uas hla, ntev thiab dav ntawm lub manhole npog yuav tsum tau txiav txim raws li qhov loj ntawm lub manhole npog.
2. Thaum txhim kho qhov sib xyaw manhole npog rau ntawm cov cement pavements, ua tib zoo saib xyuas lub qhov dej ntawm lub taub hau masonry yuav tsum tau nchuav nrog pob zeb, thiab tsim kom muaj lub nplhaib tiv thaiv pob zeb rau ntawm qhov chaw rau kev saib xyuas li 10 hnub.
3. Thaum txhim kho manhole composite npog ntawm asphalt pavements, yuav tsum tau them nyiaj mloog kom tsis txhob ncaj dov ntawm lub manhole npog thiab ncej rooj zaum los ntawm kev tsim machinery kom tsis txhob muaj kev puas tsuaj.
4. Yuav kom tswj tau qhov zoo nkauj ntawm lub manhole npog thiab qhov tseeb ntawm kev sau ntawv thiab qauv, ceev faj kom tsis txhob stain lub manhole npog thaum nchuav asphalt thiab cement rau ntawm txoj kev.

Cov khoom siv zog ntawm cov khoom yog ntau tshaj 1200 kg ib cubic centimeter, thiab tag nrho cov load peev xwm ntawm lub manhole npog nyob deb tshaj lub teb chaws tus qauv, uas overcomes ntau yam shortcomings ntawm composite manhole npog uas feem ntau yog txhawb los ntawm steel tuav nyob rau hauv lub lag luam;kev tiv thaiv tub sab nyiag yog qhov kev daws teeb meem vim nws tsis muaj nqi rov ua dua tshiab.Cov teeb meem kev sib raug zoo ntawm qhov ploj lawm manhole npog;qhov tsis muaj suab nrov daws cov suab nrov los ntawm dov ntawm cov khoom siv hlau;geometric loj tsim daim ntawv cog lus ntawm lub hau tsis dhia kom ntseeg tau tias cov khoom tsis tig los yog hloov tom qab lub tsheb nrawm dhau;tus tsim yog tsim nyog, installation, yooj yim rau qhib, thiab yooj yim rau kev soj ntsuam thiab txij nkawm ntawm underground pipeline chaw;zoo nkauj tsos, ntshiab cam khwb cia qauv, zoo heev anti-slip kev ua tau zoo, thiab pleasing xim;corrosion kuj, tsis muaj xeb, soaked nyob rau hauv sulfuric acid tov nyob rau hauv ib tug kub ntawm 40 ℃ thiab ib tug concentration ntawm 60% rau 24 teev, cov khoom tsis muaj qhov txawv txav tshwm sim;Lub neej ua haujlwm ntev Tom qab kuaj kev laus, cov khoom lag luam muaj lub neej ua haujlwm ib txwm muaj ntau tshaj 20 xyoo hauv qab -40 ℃ ~ 100 ℃ qhib cua txias;Nws yog dav siv rau cov tuam txhab muab dej, tuam txhab vaj tsev, tuam txhab hauv nroog, tuam txhab xov tooj, xov tooj cua thiab TV, kev sib txuas lus, tuam txhab hluav taws xob, roj, Lub Tuam Txhab Kub Kub
