Arov ua los ntawm Polypropylene random co-polymer, uas ua rau lawv ruaj khov dua, yooj yim rau nruab, thiab tiv taus qhov kub thiab txias.
Txawm li cas los xij, ib yam li lwm yam khoom siv kav dej, kev siv cov kav dej PPR yuav tsum tau ceev faj kom ntseeg tau tias lawv siv tau zoo thiab muaj txiaj ntsig. Kab lus no yuav qhia txog qee qhov kev ceev faj tseem ceeb tshaj plaws uas yuav tsum tau xav txog thaum siv cov kav dej PPR.
1. Cov txheej txheem txhim kho kom raug:
Thawj thiab qhov tseem ceeb tshaj plaws ceev faj thaum nws los txog rau kev siv cov kav dej PPR yog los xyuas kom meej tias lawv raug ntsia kom raug. Cov txheej txheem kev teeb tsa kom zoo tuaj yeem txhim kho lub neej ntawm PPR kav dej thiab yuav pab kom tsis txhob tawg thiab tawg.
PPR cov kav dej yuav tsum tau siv PPR vuam tshuab uas yaj cov kav dej yas thiab cov pob qij txha ua ke los tsim kom muaj kev sib txuas. Nws yog ib qho tseem ceeb uas cov hlau vuam yog teem rau ntawm qhov kub thiab txias, thiab qhov tob qhov tob yuav tsum zoo meej kom tsis txhob muaj qhov nkag tsis txaus ntawm cov yeeb nkab rau hauv qhov haum.
2. Tsis txhob siv cov tshuaj hnyav hnyav:
Lwm qhov kev ceev faj tseem ceeb rau kev siv cov kav dej PPR yog tsis txhob siv cov tshuaj hnyav. PPR kav dej tiv taus cov tshuaj corrosion, tab sis raug rau cov kua qaub los yog alkaline heev tuaj yeem ua rau cov kav dej puas.
Yog li ntawd, nws yog ib qho tseem ceeb kom tsis txhob siv cov tshuaj xws li acids, alkalines, tshuaj tua kab, lossis lwm yam khoom tsis zoo nyob rau hauv kev sib cuag nrog PPR kav.
3. Kev Tswj Kub Kub:
PPR kav dej paub tias tiv taus kub txog 95 degree, ua rau lawv zoo tagnrho rau kev siv dej kub. Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum tau ceev faj kom tsis txhob overheating cov kav dej.
Overheating tuaj yeem ua rau deformation lossis melting ntawm cov kav dej, ua rau cov dej xau. Nws yog ib qho tseem ceeb kom tswj tau qhov kub thiab txias hauv qhov kev pom zoo, ob qho tib si thaum lub sij hawm installation thiab kev siv tiag tiag.
4. Lubrication zoo:
Kev lubrication ntawm PPR cov kav dej thiab fittings yog qhov tseem ceeb los ua kom yooj yim installation, txhim khu kev ruaj ntseg, thiab tiv thaiv kom tsis txhob xau. PPR cov kav dej tuaj nrog lub ntsej muag du, uas ua rau nws nyuaj rau cov fittings ua raws.
Lubricating cov fittings nrog lubricants xws li xab npum tuaj yeem pab txo qis kev sib txhuam, yog li ua kom nrawm nrawm ntawm cov kav dej thiab cov fittings.
5. Kev tshuaj xyuas tsis tu ncua:
Kev tshuaj xyuas tsis tu ncua yog qhov tseem ceeb thaum siv cov kav dej PPR. Kev tshuaj xyuas ib ntus tuaj yeem pab txheeb xyuas qhov kev puas tsuaj lossis muaj peev xwm xau, uas tuaj yeem ua rau muaj kev puas tsuaj loj thiab dej khib nyiab.
Nws yog ib qho tseem ceeb uas yuav tsum tau soj ntsuam cov kav dej tsis tu ncua ua ntej thiab tom qab kev teeb tsa thiab thaum siv los xyuas kom meej tias cov kav dej zoo tag nrho.
6. Zam kev puas tsuaj:
Kev puas tsuaj yog ib qho tseem ceeb tshaj plaws ntawm PPR yeeb nkab tsis ua hauj lwm. Nws yog ib qho tseem ceeb kom tsis txhob nthuav tawm cov kav dej rau kev puas tsuaj xws li kev cuam tshuam lossis kev sib tsoo.
Nws yog ib qho tseem ceeb kom tsis txhob nthuav tawm cov kav dej kom hnyav lossis hnyav vim qhov no tuaj yeem ua rau cov kav dej ntau dhau ua rau deformation lossis tawg.
7. Xaiv cov kav dej zoo PPR:
Kev xaiv ntawm cov kav dej PPR yog qhov tseem ceeb thaum nws los txog rau kev ceev faj. Nws yog ib qho tseem ceeb los xaiv cov kav dej zoo PPR uas ua tau raws li cov qauv kev lag luam.
Cov kav dej tsis zoo yuav tsis muaj qhov yuav tsum tau muaj zog, ua haujlwm ntev, lossis kev ntsuas siab, ua rau tawg lossis tawg.
Xaus:
PPR kav dej yog ib qho kev daws teeb meem zoo tshaj plaws thaum nws los txog rau dej, cua sov, thiab cua txias. Lawv yog cov yooj yim rau nruab, ruaj khov, thiab raug nqi.
Txawm li cas los xij, kev siv cov kav dej PPR yuav tsum tau ua tib zoo saib xyuas kom ntseeg tau tias lawv tau nruab thiab siv kom raug. Cov txheej txheem kev teeb tsa kom raug, zam cov tshuaj hnyav, kev tswj xyuas qhov kub thiab txias, thiab kev tshuaj xyuas tsis tu ncua yog qee qhov tseem ceeb tshaj plaws uas yuav tsum tau xav txog.
Nrog kev saib xyuas kom zoo, cov kav dej PPR tuaj yeem nyob tau ntau xyoo, providing txhim khu kev qha thiab siv tau cov kav dej daws teeb meem.
