Tsuas yog hais txog cov complex: polypropylene kav, lawv qhov loj me thiab kev ua haujlwm

Peb qhia seb cov kav dej twg nws yog qhov zoo dua los xaiv rau kev muab cua sov thiab dej.

Tus qauv hluav taws xob ntawm cov hlau maj mus rau hauv keeb kwm, muab txoj kev rau cov neeg ruaj khov tshiab, nrog rau kev pheej yig analogs. Raws li nrog txhua lub tsev siv, lawv muaj lawv tus kheej qhov zoo lossis qhov tsis zoo. Xaiv polypropylene leeg, qhov ntev yuav tsum tau soj ntsuam kom zoo thiab paub txog cov cim nta. Noj txog nws thiab tham.

Ua ntej tshaj plaws, nws yog ib qho tseem ceeb kom paub txoj kab uas hla ntawm polypropylene Cheebtsam rau cov dej thiab cua sov. Muaj ntau ntau ntau ntau yam, lawv raug sib cais los ntawm cov phab ntsa thickness, hydraulic xam thiab kub tsoom fwv, uas muaj peev xwm sawv ntawm tiv.

• PN 10 - Lawv muaj cov phab ntsa thinnest, uas txhais tau tias nws tsis zoo tshaj plaws tsis sim nrog dej kub thiab siv rau kev muab dej txias. Qee zaum lawv kuj tau siv thaum txhim kho chav sov. Cov khoom lag luam nrog khij pn 10 tuaj yeem tiv thaiv cov dej kub kom txog li 45 degrees thiab lub siab siab tshaj ntawm 1 MPA.
• PN 16 yog qhov siab dua, kev khiav hauj lwm siab txog li 1.6 MPa, thiab cov dej uas pom zoo kom sov rau + 60 ° C.
• PN 20 - Raws li cov phab ntsa tuab ntxiv nce, cov khoom siv ua kom thev naus laus zis tau loj hlob. Ntawm no koj tuaj yeem teeb tsa 80 degrees ntawm tshav kub hauv dej thiab sim lub siab ntawm 2 mpa.
• PN 25 yog qhov kev xaiv ruaj khov tshaj plaws. 95 degree nrog yuav luag npau npau yog tswj, nrog rau kev ua haujlwm siab ua haujlwm nrog ib qho 2.5 MPA siab.

Ntxiv rau cov ntsuas no, nws yog kev cai los faib cov qauv ntawm ib-txheej thiab multilayer. Qhov kev xaiv thib ob yog nruab nrog fiberglass, ntawv ci thiab basalt fiber. Vim li cas koj thiaj xav tau nws? Qhov kev txhawb nqa txheej tshaj, qhov tseeb, tag nrho cov kev sib ntxiv no tau tso cai rau cov phab ntsa kom ruaj khov, thiab yog li ntawd nws yog kom muaj zog tshaj tawm, kev kub. Txoj kev pheej hmoo ntawm kev nthuav dav qhov loj ntawm dej kub yog txo, uas feem ntau tshwm sim thaum ua haujlwm nrog polypropylene.

Yuav ua li cas tsis txhob yuam kev thaum xaiv qhov ntau thiab tsawg

Dab tsi koj yuav tsum paub, mus rau tom khw muag khoom rau cov khoom lag luam? Yuav pib nrog - kev ua haujlwm. Lub installation ntawm cov dej nrog cov dej haus? Lossis koj puas npaj cua sov, lossis chav sov sov? Ntseeg kuv, nyob rau hauv tag nrho cov xwm txheej uas lub tshuab uas sib txawv rau cov kav dej polypropylene hauv hli yuav txawv. Hais tias yog vim li cas cov khoom siv tau yuav nyob rau hauv ib txoj haujlwm kev tsim kho tshwj xeeb. Ntxiv rau qhov ua haujlwm yooj yim, nws yog qhov tsim nyog los xav txog seb muaj cua sov hauv chav uas lub installation yuav ua.

Cov yam ntxwv thiab siv cov kev xaiv

Txhawm rau kom pom tseeb qhov koj xav tau, nws yog qhov zoo tshaj plaws los hais txog lub rooj rau polypropylene kav. Muaj koj xav nrhiav qhov kub ntawm kev txaus siab, qhov loj me yog qhov cim uas sib haum rau cov ntsuas uas xav tau yuav yog koj cov kev qhia.

Qhov ntev ntawm polypropylene kav hauv nti hauv nti thiab mm yog teev - qhov no yog ua kom yooj yim, txij li kev lag luam ntawm txawv teb chaws muaj lawv tus kheej siv.

Cov khoom siv xaiv raws li cov yam ntxwv ntawm kev siv

• RRN - Homopolers, nws muaj nqi siv tsuas yog dej txias.
• RRV - Thaiv cov ntawv luam tawm, kuj yog qhov zoo rau dej txias, qee zaum lawv tseem siv thaum txhim kho chav sov.
• PPR yog lub ntsej muag polypropylene copolymer, cov nrov tshaj plaws, tuaj yeem tiv tauj nrog cov dej kub, dej txias, sov pem teb lossis cua sov.
• PPS yog qhov kev xaiv txhim kho nrog cov kub siab dua. Infrequently pom nyob rau hauv cov tsev nyob hauv tsev.

Txhawm rau nteg dej nrog dej txias, suav nrog kev haus dej, cov khoom lag luam ncaj nrog cov cim PN10. Pipeline tsev neeg tsis muaj cov kev siab siab ntawm tsev neeg, raws li txoj cai, nws tsis yog ntau dua 1 MPa, thiab dej qis tsis ua rau kev nthuav dav.

Polypropylene kav rau cua sov, qhov ntau thiab tsawg ntawm uas yog nyob rau hauv lub rooj saum toj no, nws yog ntshaw kom siv txhawb nrog ntawv nyiaj lossis basalt. Tom kawg tau tshwm sim tsis ntev tas los no tsis ntev tas los no tsis ntev tas los no tsis ntev tas los no thiab muaj tsawg tus neeg uas ua haujlwm nrog nws, tab sis cov ntaub ntawv twb tau txais kev txheeb xyuas qhov zoo. Vim li cas kuv xav tau kev txhawb zog? Qhov no yog ib qho tseem ceeb heev hauv kev tsim cov dej kub, vim tias vim lub gasket thaum raug kom kub, propylene tsis hloov nws cov duab thiab loj. Thiab nws txhais tau tias yuav tsis muaj deformation uas tuaj yeem ua rau xau. Sab hauv lub taub ntawm polypropylene kav, lub rooj nrog uas tau nthuav tawm saum toj no, ua tsawg dua, tab sis cov ncauj lus tseem tsis hloov.

Cov Kev Cai thiab Cov Lus Qhia Cov Tswv Yim Txhawb

• Qhov yooj yim tsim yog ib-txheej. Txhawm rau tsim lawv, thawj cov khoom yog txiav tawm nrog cov yeeb nkab cutters, tig cov npoo thiab muab cov qauv tsim uas siv cov fittings lossis kua nplaum.
• Multilayer mounted raws li qhov sib txawv nkaus xwb - thaum ua haujlwm nrog lawv tsis tuaj yeem siv tshuaj txias, nws yuav tsis muab kev sib txuas rau txhua txheej. Feem ntau, cov txheej txheej ntau txheej txuas nrog los ntawm kub vuam lossis siv cov fittings tshwj xeeb.
• Kev txhawb nqa cov kav dej xav tau kev npaj tshwj xeeb ua ntej kev teeb tsa. Qhov khoom yog tias cov ntawv ci txhuas yog txuas rau cov fiber ntau ntawm cov kua nplaum, uas txhais tau tias muaj qee qhov kev pheej hmoo ntawm cov tev. Txhawm rau zam qhov no, ua ntej vuam cov khoom nrog kev txhawb cov khoom siv, nws yog qhov tsim nyog kom tshem tawm cov ntawv ntawm ntug, thiab tom qab ntawd sch fiber ntawm ob sab. Los ntawm cov kev tiv thaiv no, cov dej yuav tsis nkag mus, uas txhais tau tias cov raj xa hluav taws xob yuav nyob ua lej.

Yuav ua li cas xyuam xim rau kev xaiv ntawm fittings

Raws li txoj cai, fittings rau cov khoom tom ntej yog ua los ntawm thermoplast. Cov ntaub ntawv no yog qhov rhiab heev rau qhov ntsuas kub thiab txias thiab tuaj yeem tawm tsam thaum raug cua sov. Yog vim li cas koj yuav tsum xaiv cov khoom siv nrog kev saib xyuas tshwj xeeb. Yuav ua li cas tsis ua yuam kev?

• Rau dej kub, compression fittings yuav tsis haum. Lawv deformed thaum compressed thiab tuaj yeem ua rau cov raj xa dej tawg. Nws yog qhov zoo dua los siv American - ib lub xov hluav taws xob yooj yim disassembled, uas txhais tau tias nws yuav yooj yim rau hauv qhov no.
• Nco ntsoov xyuas nrog cov cim thiab Gost thaum yuav cov khoom - nws yuav tsum ua kom ze rau txoj kev tsim. Piv txwv li, yog tias koj ua haujlwm nrog soldering, nws yog ib qho tseem ceeb kom xaiv ob qho khoom lag luam los ntawm tib cov ntaub ntawv.
• Tsis txhob yuav hloov kho, crumpled lossis txawm tawg fittings. Tej yam me me uas koj tsis tau coj mus rau hauv tus account yuav ua rau kom tawg ntawm tag nrho cov dej.
