Polypropylene raj, siv tam nrog iav fibers, rau cua sov. Nta, zoo thiab tsis zoo

Thaum arrangement ntawm niaj hnub cua sov tshuab siv tshwj xeeb kev sib txuas lus. Feem ntau niaj hnub no raj polypropylene, siv tam nrog iav fiber, tus nqi ntawm uas yuav sib txawv los ntawm 51 mus 144 rubles. rau TDG. m. Technical specifications ntawm cov khoom no tso cai rau koj mus siv lawv nyob rau hauv lub feem ntau high-kub tej kev kawm.

Lub ntsiab zoo

Polypropylene raj, siv tam nrog iav fibers, rau cua sov ib tug plurality ntawm yam ntxwv. Cov lawv:

• tsawg luj;
• lub dag lub zog;
• muaj yog tsis muaj kev nce rau hauv lub lag luam.

Rau cov yog vim li cas hais tias cov khoom muaj ib tug uas tsis muaj ceeb thawj, yog lawv yog heev yooj yim mus rau Mount nyob rau hauv kev sib txuas lus tshuab ntawm nws tus kheej. Ntawm lwm yam, lawv lub zog tso cai rau lawv nyiaj mus dhau hnyav kub hloov. Kav muaj siab yooj. Uas yog vim li cas nrog rau cov kev pab los ntawm lawv koj yuav equip ib arbitrarily complex systems. Nyob rau lawv puab nto nrog lub sij hawm tsis ua rau kom cov mineral residue uas yuav tsum tau hu ua ib tug loj ntxiv.

Lub ntsiab disadvantage

Polypropylene raj, siv tam nrog fiberglass (rau cov cua kub), muaj ib tug tseem ceeb drawback. Nws yog qhia nyob rau hauv lub tsawg kub thaum lub sij hawm lub lag luam. Nws yog sib npaug zos rau 95 ° C. Yog hais tias qhov no txwv yuav zoo tshaj, thiab qhov kub thiab txias yuav mus txog 140 ° C, lub raj dej system yog tsuas melted. Nyob rau hauv kev txiav txim kom tsis txhob muaj xws teeb meem, tus tsim thiab txhawb nqa qhov khoom hlau.

rau cov ntaub ntawv

Qhov cuab lub zog yog ib txoj kev ntxiv dag zog rau kev sib txuas lus tshuab. Ua li no, txhuas yog siv nyob rau hauv lub ntsiab. Tig cev yuav ua tau nyob rau hauv nruab nrab thiab sab hauv. Nyob rau hauv lub caij nyoog kawg no rooj plaub no nws yog tau mus cuag zoo tau, raws li muaj ib tug siab yuav qhov muaj tseeb uas lub puab phab ntsa yuav ua rau kom ntsev deposits. Cov feem ntau yas siv tam nrog txhuas nyob rau hauv nruab nrab.

German Specifications tam kav

Cov feem ntau lately polypropylene raj. Tam 25 hli nyob rau hauv txoj kab uas hla, piv txwv li, yuav tau tsim nyog 83 rubles. rau TDG. m. Nyob rau hauv xyoo tsis ntev los, nrov heev German kav uas ntxiv dag zog rau nrog iav fiber nyob rau hauv lub center. Tej khoom muaj ib tug tseem ceeb coefficient ntawm expansion. Nws yog Cr = 0,009 hli / m. Nyob rau hauv cov kav dej muaj thicker phab ntsa nyob rau hauv kev sib piv nrog cov khoom siv tam nrog txhuas ntawv ci.

Lawv yog cov tsim rau dai dej kub mov systems thiab lub cua sov, xws li cov installation ntawm hauv pem teb cua kub los yog cua sov, raws li zoo raws li lub koom haum ntawm kua. Lawv yog cov tau nyiaj mus dhau pressures mus txog ob peb atmospheres, zoo li hlau standpipes. Qhov kub ntawm cov ua hauj lwm nruab nrab yuav ncav cuag 120 ° C thaum lub txheem nqi yog 95 ° C.

Main yam ntxwv ntawm tus tshiab polypropylene hlab PPRC, fiberglass tam

Polypropylene raj, siv tam nrog iav fibers, muaj impressive kev kawm rau cov cua kub. Ntawm lawv, - ib tug ntom uas yog 0.9 g / cm ^3. Nws yuav tsum raug sau tseg melting kub - 1490 ° C. Tensile zog mas nws txawv ntawm 34 mus 35 N / MMA, whereas lub tawm los kev nyuaj siab yuav ua tau sib npaug zos rau 24 mus rau 25 N / hli. Tawm expansion yog 0.15 hli / m, tab sis thermal conductivity ntawm 200 ° C yog 0,24 W / m. Cov tshav kub muaj peev xwm nyob rau tib lub kub theem yog 2 kJ / kg. Tej kav yuav siv tau xwb tsis rau tus arrangement ntawm cov cua kub, tab sis kuj rau lub lag luam ntawm sib uas siv compressed cua. Cov khoom uas yog tsim rau pipeline tes hauj lwm siv nyob rau hauv cov nqe lus ntawm ua liaj ua teb thiab kev lag luam.

Cov yam ntxwv nyuaj fiberglass yeeb nkab ntawm PP-R

Yog hais tias koj xav nyob rau hauv polypropylene kav, siv tam nrog iav fiber, rau cua sov, ces koj yuav xav txog ib tug ob peb manufacturers, xws li Italian, Czech, Turkish, German thiab Lavxias teb sab. Nyob rau hauv thawj cov ntaub ntawv, lub raj yuav tsum ua nyob rau hauv 20 tuav. Nyob rau tib lub sij hawm khoom Czech, Turkish, German thiab Lavxias teb sab ntau lawm uas tsim tau rau 25 bar nyob rau hauv thawj cov ntaub ntawv. Thiab 20 bar - nyob rau hauv tag nrho cov lwm leej lwm tus. Qhov siab tshaj plaws kev khiav hauj lwm kub ntawm Italian kav, Czech, Turkish, German thiab Lavxias teb sab ntau lawm yog 950, 800, 950, 900 thiab 1100 ° C feem. Txhua yam ntawm cov khoom no muaj tib cov kev pab lub neej, uas yog 50 xyoo.

Yog hais tias peb xav txog cov kav dej nyob rau hauv cov nqe lus ntawm lub txheej inch, nyob rau hauv thawj cov ntaub ntawv tej zaum nws yuav sib txawv los ntawm 20 mus rau 63, nyob rau hauv lub thib ob - los ntawm 16 mus rau 125, nyob rau hauv lub thib peb - los ntawm 20 mus rau 110, nyob rau hauv plaub - los ntawm 20 mus rau 125, thiab nyob rau hauv lub thib tsib - los ntawm 20 mus rau 110 hli. Tej kav no yog ua los ntawm polypropylene siv tam nrog iav fiber, tus nqi ntawm uas justifies cov yam ntxwv tej zaum yuav siv tau rau koom haum pab cov cua kub thiab domestic dej kub. Mus saib lawv cov kev xyaum, qhov zoo tshaj plaws zoo, nws yog tsim nyog los ua raws li cov chaw tsim tshuaj paus lub tswv yim pom zoo, uas yog qhia nyob rau hauv cov cais tawm ntawm qhov nruab nrab txheej ntawm reinforcing kev sib cuag nrog dej. Ntawm lwm yam, thaum lub sij hawm installation nws yog pom zoo kom siv ib tug tshwj xeeb milling cutter.

ntxiv tsis zoo

Yog hais tias koj xaiv rau mount lub cua sov polypropylene kav, koj yuav tsum tau ua ntau me ntsis txog cov lawv lub ntsiab tsis zoo. Lawv hais nyob rau hauv tsis zoo feem ntawm ultraviolet tawg rau cov khoom, li zoo li nyob rau hauv lub linear expansion. Lub hnub lub sab txhoj puab heev tej yam rau cov qauv ntawm cov polymers, thiab tom qab tso lawv muaj peev xwm tsis tsum sab laug tawm sab nraud yuav tsum tau muaj kev tiv thaiv cov khoom. Lub downside yuav hu ua thiab lub linear expansion. Nws yog ob zaug kom ntau li ntau piv nrog hlau kav. Cov yav tas feature ua rau qhov yuav tsum tau ntawm qhov cuab lub zog.

Khoom manufactured los ntawm ob extrusion. Nyob rau tam ncej rau imposing siab rau cov txheej thiab puab sab yog thov mus rau lub thermoplastic polymer. Yas nyob rau hauv cov huab cua yuav siv sij hawm lub hardness. Thiab thaum kawg tswj kom tsim ib tug muaj zog daim ntawv cog lus nrog ib tug khoom ncej.

Yuav ua li cas lwm tus yuav tsum xyuam xim rau?

Tam yas kav, tus yam ntxwv uas yog nyob rau hauv tsab xov xwm, muaj ib tug muaj zog lub cev pob txha nyob rau hauv daim ntawv ntawm cov iav fibers. Sandwich Siv muaj txheej thiab ib puab txheej ua los ntawm polypropylene thiab cov reinforcing iav fiber tsim. Thaum lub sij hawm extrusion, cov ntaub ntawv yog sintered rau hauv ib lub khoom qab zib thiab tsim ib cov yeeb nkab lub cev. Tej khoom muaj ntau yas, thiab lawv txoj kab uas hla tej zaum yuav mus txog 125 hli.
