Rwb thaiv tsev cov ntaub ntawv rau cov kav dej ua los ntawm polyethylene ua npuas ncauj: qhov luaj li cas, tus yam ntxwv, cov duab

Thaum pw thiab lag luam ntawm pipelines ntawm txhua yam yuav tsum tau lo lus uas peb ua tau ib co kev cai, txwv tsis pub koj yuav pom me ntsis tag nrho cov hom teeb meem.

qhov yuav tsum tau siv

Sewer thiab kav xa dej, uas yog nyob sab nraum los yog sab hauv lub unheated chav, yuav khov. Nrog kev xav txog cov cua kub system, lawv yuav tsum tau tiv thaiv kom txhob kub poob, raws li zoo raws li tej yam kub ntawm lub coolant. Rau kev tiv thaiv nyob rau hauv lub piav mob siv tso cua sov rau cov kav dej ua los ntawm polyethylene ua npuas ncauj.

Ntsiab nta

Qhov saum toj no hais cov ntaub ntawv uas muaj ib tug tshwj xeeb cov qauv uas muaj me me kaw hlwb, nws ceev yuav ua ncaj rau cov duab nyob rau hauv txoj kev khwv los ntawm 25 mus 40 kilograms ib cubic Meter. Polyethylene muaj zoo heev elasticity txawm thaum raug tsawg kub, thiab nws cov khoom ua tsis hloov ntawm lub ntau yam ntawm -60 thiab +90 degrees. Qhov no qhia tau hais tias cov rwb thaiv tsev rau cov kav dej ua los ntawm polyethylene ua npuas ncauj yuav muab ntsia tau rau hauv tej huab cua tej yam kev mob. Foamed polyethylene rwb thaiv tsev coefficient siab txaus, txij thaum lub thermal conductivity yog tsawg tsawg thiab mas nws txawv ntawm 0,038 mus 0,039. Dej vapor permeability yog 0,001, uas tso cai rau cov ntaub ntawv uas ua kom pom qhov zoo ntawm cov ua kom tiav vapor kuj. Nws yog kev kawm mus rau ntau yam loads, thiab raws li lub zoo tshaj plaws ntawm no yog daim duab ntawm 0.3 MPa. Rwb thaiv tsev rau cov kav dej ntawm polyethylene ua npuas ncauj muaj ib lub suab haum uas yog 16 decibels, li ntawd, cov ntaub ntawv uas yog excellently absorbs suab thiab deeg uas tej zaum yuav tshwm sim thaum lub sij hawm ntawm kev siv cov pipeline systems. Nws yuav tsum tau muab sau tseg thiab rau yav tom ntej hydrophobicity yog li no nyob rau hauv ncaj qha kev sib cuag nrog lub kua yog tau yuav absorbed rau hauv lub xeem 1% ntawm tag nrho cov ntim. Qhov siab tshaj plaws nqi ntawm cov dej haum yog 3.5%. Uas yog vim li cas lub styling tsis hais qhov yuav tsum tau rau waterproofing ua hauj lwm, txij li thaum lub qhov chaw yuav tsis tsim ib tug condensate. Thaum tshav kub kub rwb thaiv tsev rau cov kav dej ua los ntawm polyethylene ua npuas ncauj excellently tiv nrog tus ntawm sib active tshuaj ntawm lub hom roj av, roj, kua qaub thiab alkalis.

ntxiv nta

Piav rwb thaiv tsev yog manufactured nyob rau hauv raws li GOST 30244-94. Foamed polyethylene yuav dej num raws li muaj mob pesnrab combustible cov ntaub ntawv, lub ignition kub nyob rau hauv qhov ncaj nplaim raug ntawm 306 degrees. Rau tus kheej-tiv cav tseb yog 416 degrees yog txaus. Txawm li cas los, nws yog suav tias yog ib tug ntxiv kom zoo dua hais tias cov rwb thaiv tsev yog tsis lom txawm thaum hlawv, nyob rau hauv tus txheej txheem, nws tsis emit teeb meem vapors rau tib neeg lub cev.

yam ntxwv

Yog hais tias koj yog txaus siab nyob rau hauv rwb thaiv tsev rau cov kav dej ua los ntawm polyethylene ua npuas ncauj, koj yuav tsum xav txog tag nrho nws cov zoo. Heev feem ntau, cov khoom yog muab piv nrog polystyrene ua npuas ncauj thiab polyurethane ua npuas ncauj, yog li ntawd yuav paub qhov txawv ntau yam zoo, ntawm lawv - me ntsis thermal conductivity, los ntawm kev uas yog tau muab ib tug zoo kev foob uas muaj ib tug me me thickness. Nws yuav tsum tau muab sau tseg, thiab xws li ib tug zoo li tensile lub zog, thiab kuj zoo heev muaj peev xwm rov qab kho cov daim ntawv pib tom qab deformation. Nyob rau hauv ua npuas ncauj yuav muaj kev cuam tshuam xis mas, gypsum, txiv qaub thiab ua vaj tse, tsis muaj prejudice rau cov zoo cov yam ntxwv. Rau cov yog vim li cas hais tias cov qhia tawm rhaub yog kiag li txawm, tsis tsuas yog rau cov tib neeg, tiam sis kuj rau cov ib puag ncig, nws yog tau tso cai rau siv nyob rau hauv qhov kev lag luam, nyob hauv tsev, nyob rau hauv cov tsev kho mob thiab cov tsev ntawm lub lag luam ua noj. Polyethylene muaj cov qualities ntawm hydrophobicity uas tsim tej yam kev mob uas tshem tawm qhov tshwm sim ntawm pwm thiab pwm. Nws yuav tsum tau muab sau tseg, thiab yooj yim ntawm installation, t. Yuav kom. Cov khoom ua nyob rau hauv daim ntawv ntawm hollow hlab uas yuav siv tau rau ib tug luv luv lub sij hawm kom sov cov yeeb nkab, siv ntxiv cov cuab yeej thiab cov khoom siv rau lub hom phiaj no. Material nqi yog 2 lub sij hawm tsawg dua nyob rau hauv kev sib piv nrog zoo xws li cov kev daws teeb meem, uas yog vim li cas qhov no hom ntawm rwb thaiv tsev siv los ntawm tau txais kev pab yog nce.

Ib co ntawm cov tsis zoo yam ntxwv

Thermal rwb thaiv tsev rau cov kav dej ua los ntawm polyethylene ua npuas ncauj, tus yam ntxwv uas yog nyob rau hauv tsab xov xwm, muaj ib co tsis zoo, ntawm lawv, raws li hais saum toj no, muaj peev xwm mus hais ntxiv rau combustion thiab flammability thaum nplaim taws raug. Vim li no, cov ntaub ntawv uas muaj peev xwm siv tsis tau nyob rau lub chaw uas yuav tsum tau raws li siab tua hluav taws kev ruaj ntseg uas yuav tsum tau. Ntawm lwm yam, ua npuas ncauj collapses nyob rau hauv tus ntawm ncaj qha tshav ntuj. Qhov no qhia qhov yuav tsum tau mus khaws thiab tuav cov yeeb nkab rwb thaiv tsev nyob rau hauv cov chaw uas cais los ntawm uas nkag mus rau ultraviolet. Yuav kom daws tau qhov teeb meem no, ib cov khoom yog xaiv uas muaj ib tug opaque zaj duab xis. Shortcomings yooj yim compensated los ntawm cov saum toj no-hais zoo.

Qhov ntev thiab lwm yam ntxwv

Yog hais tias koj xav siv rwb thaiv tsev rau cov kav dej ua los ntawm polyethylene ua npuas ncauj, qhov luaj li cas ntawm cov uas muaj peev xwm sib txawv los ntawm 6 mus rau 160 hli, nws yog tsim nyog los paub tag nrho cov ntau ntau yam ntawm nws cov diameters. Yog li, cov phab ntsa thickness tej zaum yuav sib npaug zos rau cov duab nyob rau hauv lub chav rau mus rau peb caug-ob millimeters. Kev ua lag luam yuav nrhiav tau ib cov yeeb nkab rwb thaiv tsev, uas yog muab nrog ib tug tshwj xeeb daim nyias nyias, muaj ib tug dawb lias polymeric txheej. Nws tiv thaiv tiv tshav ntuj kub raug, uas tso cai rau kev siv ntawm cov khoom no, txawm nyob rau hauv qhov chaw uas yog lossi raug ultraviolet lub teeb. Ntawm lwm yam, rwb thaiv tsev rau cov kav dej ua los ntawm polyethylene ua npuas ncauj, uas cov duab no yog nyob rau hauv tsab xov xwm tej zaum yuav ib daim ntawv los yog yob. Tej zaum thaum lub sij hawm siv thiab los yog rwb thaiv tsev complemented foiled nplaum.

Tus qauv ntawm lub plhaub

rho tawm daim ntawv yuav tsum tau raws li tej yam uas yuav tsum tau hais tias cia nws mus puag khawm ib tug saum npoo nrog tsawg heev khoob. Cov khoom yuav tsum tsis txhob yuav deformed, thiab rau hauv daim ntawv yuav tsum muaj ib yam kab uas hla. Tsuas yog nyob rau hauv no txoj kev yuav tsum tau muab ib tug tseem ceeb tshaj plaws ntawm rwb thaiv tsev. Yuav ua kom yooj yim installation raws lub raj, raws li ib tug txoj cai, nws yog ib tug hauj incision, uas tso cai rau ua installation ua hauj lwm nyob rau hauv lub shortest tau lub sij hawm thiab nyob rau hauv lub tshuab uas yog twb ntsia.

Nta ntawm lub installation

Yog hais tias koj txiav txim siab los siv rau rwb thaiv tsev, rwb thaiv tsev rau cov kav dej ua los ntawm polyethylene ua npuas ncauj, txoj kab uas hla yog tsim nyog los xaiv lub zoo meej tshaj plaws. Tom qab hais tias, nws yog ib qho tseem ceeb ua raws li cov installation ntawm rwb thaiv tsev technology. Hlab yog npaj rau cov txheej txheem, thiab lawv nto yog ntxuav los ntawm av thiab plua tshauv. Polyethylene yog muab tso rau hauv ib tug stocking hom uas yuav tsum tsis txhob txuam nrog rau kev teeb meem. Qhov no yuav ua tau nyob rau yeeb nkab tsis tau ntsia, lub rwb thaiv tsev yuav tsis yuav puas ntsoog nrog ib tug riam.
