Composite resin manhole npog yog suppressed
1. Khoom nta ntawm composite resin manhole npog
(1). Lub teeb yuag, qhov hnyav ntawm lub iav steel manhole npog yog li 1/4 ntawm cov hlau npog, kev tsim kho engineering thiab siv qhov qhib thiab kaw yog lub teeb thiab hloov tau;
(2). Zoo rau tus kheej xauv. Qhov tshwj xeeb txwv kev sib txuas qauv ntawm cov iav fiber reinforced yas puag ncig manhole npog thiab lub rooj zaum zoo muaj qhov ua haujlwm ntawm tus kheej txhawm rau tiv thaiv lub hau npog ntawm kev dhia tawm ntawm lub qhov dej tom qab lub tsheb hla;
(3). Siab zog. Lub zog tensile ntawm FRP cov ntaub ntawv yog sib npaug ntawm Q235 steel, thiab lub zog compressive yog ntau tshaj ob zaug ntawm C30X. Nws qhov cuam tshuam, kev vibration, qaug zog, thiab kev puas tsuaj yog zoo dua li cov hlau, hlau thiab lwm yam ntaub ntawv. Nws yog siv los ua tus qauv ntawm lub hau npog, Lub zog thiab kev nyab xeeb yog yooj yim dua kom tau raws li cov hlau manhole npog;
(4). Kev tiv thaiv tub sab nyiag thiab poob, FRP cov khoom tsis muaj cov khoom siv pov tseg. Siv los ua ib lub manhole npog tuaj yeem zam qhov kev phom sij zais ntawm steel manhole npog los ntawm kev nyiag, yog li tiv thaiv tus txiv neej thiab tsheb sib tsoo tshwm sim los ntawm manhole npog tub sab nyiag thiab txo kev poob nyiaj txiag thiab kev lav phib xaub.
(5). Corrosion kuj, iav fiber reinforced yas khoom yog lawm corrosion resistant. Nws yog siv los ua lub hau npog rau cov kua qaub, alkali, ntsev, dej phwj tuaj thiab lwm qhov chaw nruab nrab corrosive. Nws muaj technical thiab economic zoo.
2. Lub hom phiaj tseem ceeb ntawm composite resin manhole coveris tsuas yog siv rau hauv txoj kev hauv nroog, kev siv dej, kev siv hluav taws xob, kev xa ntawv thiab kev sib txuas lus, kev teeb pom kev zoo, thaj chaw nyob, kev npaj vaj tsev, kev siv roj thiab roj, tshuaj lom neeg, kev tsim cov kav dej, thiab lwm yam. engineering tej yaam num, feem ntau muab faib ua peb hom hauv qab no:
(1). Hnyav: txoj kev lossis qhov chaw nres tsheb uas cov tsheb tsav hla.
(2). Lub luag hauj lwm lub teeb: tej chaw ntsuab, hla, tsheb kauj vab txoj kab los yog txoj kev taug kev uas tsis pub tsav tsheb nkag mus.
(3). Hom ib txwm muaj: txoj kev lossis chaw nres tsheb uas cov tsheb ntawm chav kawm 10 thiab qis dua hla.
3. Compound ntoo manhole npog cov khoom siv ntau lawm
Cov khoom siv ntawm cov khoom sib xyaw ua ke yog feem ntau yog cov khoom sib xyaw manhole npog kub-xovxwm ua hydraulic xovxwm. Feem ntau siv specification yog 315-tuj plaub-kem kub xovxwm. Tsis tas li ntawd, yuav tsum muaj cov khoom siv peripheral xws li kneaders thiab pwm; tshwj xeeb, cov khoom siv raw yog npaj los ntawm kneader. BMC molding compound (BMC), cov khoom yog rhuab nyob rau lub sij hawm no, thiab ces sai sai txiav lub loj los luj lub luj, muab tso rau hauv lub pwm kab noj hniav rhuab mus rau ib tug tshwj xeeb kub (feem ntau yog hais txog 140 ° C), thiab tom qab ntawd nias lub swb. beam ceev ceev nias kom kaw lub pwm, tuav lub siab (lub sij hawm tuav lub siab nyob ntawm lub thickness ntawm lub manhole npog), eject lub pwm thiab tau txais cov khoom tiav.
