Cov thev naus laus zis tshiab thiab kev tsim kho tshiab tau siv dav niaj hnub no, suav nrog hauv kev tsim kho kev lag luam, pab tsim cov khoom tshiab uas txawv txav hauv lawv cov kev ua tau zoo dua. Ib qho ntawm lawv yog fiberglass reinforcement, uas tuaj yeem hu ua ib qho ntawm cov khoom siv ruaj khov thiab ruaj khov. Tau tshwm sim tsis ntev dhau los, nws tau txais txiaj ntsig zoo, dhau los ua lwm txoj hauv kev rau hlau fittings. Nws muaj cov muab tub lim tshwj xeeb uas ua haujlwm nrawm thiab cov khoom siv hluavtaws (polyester lossis epoxy resin).
Qhov zoo ntawm fiberglass reinforcement
Qhov nrov ntawm cov khoom siv no yog vim kev sib xyaw ua ke ntawm nws cov yam ntxwv zoo. Ib qho tshwj xeeb polymer binder fiber ntau muab kev tiv thaiv corrosion, rot thiab tshuaj tiv thaiv.
Tsawg thermal conductivity tsis txhob khov ntawm phab ntsa thiab cov hauv paus hauv lub caij ntuj no hnyav Lavxias.
Muaj qhov tshwj xeeb lub ntiajteb txawj nqus qis dua li ntawm cov khoom siv hlau, cov fiberglass analogue tsis muaj qhov qis dua rau nws ntawm lub zog. Kev sib xyaw ua ke ntawm cov khoom zoo no ua rau cov khoom siv tshwj xeeb yog nrov nrogtsim cov txheej txheem nyuaj thiab lub luag haujlwm.
Cov khoom siv hluav taws xob siab siab tshem tawm cov dej ntws tawm thiab tso cai siv cov khoom siv hauv cov qauv xws li cov ncej teeb pom kev zoo, cov kab hluav taws xob. Fiberglass yog ib qho dielectric, yog li tsis muaj hluav taws xob cuam tshuam, uas tseem ceeb heev rau cov tsev uas muaj cov cuab yeej siv siab.
Vim rau qhov ribbed profile, qhov kev txhawb nqa yog ruaj khov thiab ruaj khov rau hauv pob zeb, ua kom nws ua tiav ntau yam kev teeb tsa ua haujlwm.
Nws kuj tau txais txiaj ntsig los ntawm kev lag luam ntawm kev pom los siv cov khoom siv xws li fiberglass reinforcement. Tus nqi rau nws yog kev ywj pheej (nyob ntawm qhov tuab, nws yog 11-16 rubles ib meter) thiab tso cai rau koj txo tus nqi ntawm cov qauv tsim.
Tsis xav tau lub tshuab vuam lossis lwm yam cuab yeej thaum txhim kho. Es tsis txhob vuam, ntau yam fasteners yog siv.
Fiberglass reinforcement yog yooj yim rau kev thauj mus los, raws li nws tau muag hauv cov pas nrig thiab coils, uas tuaj yeem yooj yim haum txawm nyob hauv lub tsheb.
Flaws
Nrog tag nrho nws qhov txiaj ntsig tsis tuaj yeem lees paub, cov khoom siv no kuj muaj ntau qhov tsis zoo. Piv nrog rau steel reinforcement, nws muaj lub zog tawg tsis tshua muaj zog. Yog li ntawd, nws yog ib qho tseem ceeb uas fiberglass reinforcement tsuas yog siv nyob rau hauv cov kev lag luam uas tau hais meej meej los ntawm cov chaw tsim khoom.
Vim yog qhov qis qis ntawm elasticity, cov khoom khoov raws li qee qhov xwm txheej, yog li thaum tsim cov plag tsev, nws yog qhov yuav tsum tau ua ntxivkev txiav txim.
Cov thermal tsis kam ntawm fiberglass yog xws li qhov kub ntawm ntau tshaj 200 degrees nws lub zog poob, qhov no tsis suav nrog kev siv cov khoom siv rau kev tsim cov qauv uas muaj qhov kub thiab txias.
Scope of application
Kev siv cov khoom sib xyaw ua ke tau pom zoo los ua cov khoom siv ntxiv hauv kev cib, hauv kev tsim cov meshes thiab rods uas ntxiv dag zog rau cov kabmob muaj peev xwm ntawm cov qauv.
Nws kuj yog qhov yooj yim rau kev ntxiv dag zog rau txoj hauv kev, txuas hniav, txhawm rau tsim cov txheej txheem kaw, thaum lub sijhawm kho thiab kho ntau yam haujlwm.
Nyob rau hauv kev tsim kho ntawm txhua yam ntawm cov pob zeb tso tsheb hlau luam, hauv cov kav dej thiab cov dej kho dej, hauv kev sib tsoo, fiberglass reinforcement yog siv. Siv nws nyob rau hauv cov ntaub ntawv no yog ntau npaum li cas profitable piv rau cov hlau counterpart.
GRP yog qhov tseem ceeb hauv cov qauv uas raug corrosion (docks, wharves, thiab lwm yam)
Kev tsim cov fiberglass reinforcement
Fiberglass cov ntaub ntawv yog impregnated nrog polyester resins thiab kos los ntawm ib tug rhuab tuag los ua ib tug fiberglass profile.
Qhov thev naus laus zis tshiab tso cai rau koj los tsim cov khoom lag luam nrog ntau yam profile. Nws tuaj yeem yog pas nrig, yeeb nkab, channel, phaj, thiab lwm yam.tshuab pultrusion.
YFiberglass PCT
Qhov no yog cov khoom siv yob yooj yim heev. Nws yog tsim los siv tib yam li fiberglass reinforcement - qhov no yog fiberglass thiab polymer binders. Nws cov txiaj ntsig tseem ceeb yog ua kom yooj yim dua, ua haujlwm rau ntau yam tshuaj lom neeg thiab thermal cuam tshuam, dej tsis kam thiab kev nyab xeeb rau tib neeg kev noj qab haus huv.
Scope of application
PCT fiberglass yog tus cwj pwm los ntawm kev hnav tsis kam ua ke nrog tus nqi qis. Qhov no ua rau nws indispensable raws li ib tug txheej rau lub tshav kub-insulating txheej ntawm pipelines, uas yog nyob rau hauv ob qho tib si sab hauv tsev thiab sab nraum zoov, thaum tso underground cua sov tes hauj lwm. Hauv kev tsim hluav taws xob insulating thiab cov ntaub ntawv vov tsev, nws yog qhov nyuaj rau ua tsis muaj fiberglass hnub no. Thaum khoov, cov khoom no tsis tsim cov kab nrib pleb, uas ua rau nws yooj yim heev rau siv, thiab cov qauv ntawm nws tau txais kev zoo nkauj.
Fiberglass nkoj
Fiberglass yog cov khoom siv sib xyaw uas nyiam, yam tsis muaj kev lag luam feem ntau tsis tuaj yeem ua yam tsis muaj. Nws kuj tseem siv tau zoo hauv kev tsim cov nkoj me me vim muaj cov khoom zoo li kev ruaj ntseg, siab tiv thaiv corrosion, plasticity. Cov nkoj fiberglass hauv tsev yog nyob rau hauv kev xav tau ntau dua niaj hnub no. Hauv lawv qhov chaw tsim khoom, ib qho kev txhawb nqa mesh yog siv los tiv thaiv cov tsos ntawm cov kab nrib pleb hauv lub cev. Vibration-suppressing cov ntaub ntawv txhawb kev nplij siabsiv nkoj.
GRP tsis muaj txoj hauv kev qis dua rau txhuas hauv cov khoom ua haujlwm. Yog li ntawd, cov khoom tsim los ntawm cov khoom siv no tsis tshua muaj zog thiab txhim khu kev qha. Ntxiv rau, lawv tseem pheej yig dua. Cov nkoj ua los ntawm fiberglass tsis rot, corrode, thiab yog hais tias lawv nto yog kho nrog ib tug tshwj xeeb xim, qhov no kuj yuav tshem tawm nws fouling nrog algae.
Tau ntau xyoo, cov neeg tsim nkoj hauv tsev tau ua haujlwm tau zoo ntawm cov nkoj thiab nkoj siv fiberglass. Lub hull ntawm lub nkoj zoo li no yooj yim kho. Cov tsos ntawm qhov tsis zoo me me tuaj yeem kho tau yooj yim nrog cov resin thiab fiberglass. Nyob rau tib lub sijhawm, vim cov txheej txheem tshiab ntawm cov khoom siv, lub zog ntawm lub cev nce ntxiv.
Qhov chaw thiab lub zog ntawm fiberglass tau lees paub los ntawm ntau cov qauv ua tiav thiab cov lus tawm tswv yim los ntawm cov neeg tsim khoom. Qhov kev thov ntau ntxiv rau cov khoom siv fiberglass qhia tau hais tias qhov ua tau zoo ntawm kev siv cov khoom siv no.
