Kusankha pakati pa CPVC ndi PVC kumatha kupanga kapena kuswa dongosolo lanu la mapaipi. Kugwiritsa ntchito zinthu zolakwika kungayambitse kulephera, kutayikira, kapenanso kuphulika koopsa chifukwa cha kupanikizika.

Kusiyanitsa kwakukulu ndiko kulekerera kutentha - CPVC imagwira madzi otentha mpaka 93 ° C (200 ° F) pamene PVC imangokhala 60 ° C (140 ° F). Mavavu a CPVC nawonso ndi okwera mtengo pang'ono ndipo amakhala ndi kukana kwamankhwala bwino chifukwa cha mawonekedwe awo a chlorine.

Poyamba, mavavu apulasitiki awa amawoneka ngati ofanana. Koma kusiyana kwawo kwa mamolekyu kumapanga mipata yofunika kwambiri yomwe wopanga ndi woyika aliyense ayenera kumvetsetsa. Muntchito yanga ndi makasitomala osawerengeka ngati Jacky, kusiyana kumeneku kumabwera nthawi zambiri ndikamagwira ntchito ndi madzi otentha komwe kuli koyenera.Zithunzi za PVCakanalephera. Chowonjezera cha chlorine muMtengo wa CPVCimapatsa katundu wowonjezera womwe umapangitsa kuti mtengo wake ukhale wokwera nthawi zina, pomwe PVC yokhazikika imakhalabe yosankha bwino pamakina amadzi.

Chimachitika ndi chiyani ngati mugwiritsa ntchito PVC m'malo mwa CPVC?

Mphindi yochepetsera mtengo ingayambitse kulephera koopsa. Kusankha PVC komwe CPVC ikufunika kumapangitsa kuti pakhale ngozi, kusweka, komanso kutayika koopsa kwa makina otentha.

Kugwiritsira ntchito PVC m'madzi otentha (pamwamba pa 60 ° C / 140 ° F) kumapangitsa kuti pulasitiki ikhale yofewa komanso yopunduka, zomwe zimayambitsa kutayikira kapena kulephera kwathunthu. Muzochitika zovuta kwambiri, valavu imatha kuphulika chifukwa cha kupanikizika ikafooka ndi kutentha, zomwe zingathe kuwononga madzi ndi kuopsa kwa chitetezo.

Ndikukumbukira nkhani yomwe kasitomala wa Jacky adayika ma valve a PVC mu makina ochapira mbale kuti asunge ndalama. Patangotha ​​​​masabata angapo, mavavu anayamba kugwedezeka ndi kutuluka. Ndalama zokonzanso zidaposa ndalama zonse zomwe zidasungidwa poyamba. Mapangidwe a maselo a PVC sangathe kupirira kutentha kosalekeza - maunyolo apulasitiki amayamba kusweka. Mosiyana ndi mapaipi achitsulo, kufewetsa uku sikukuwoneka mpaka kulephera kuchitika. Ichi ndichifukwa chake malamulo omangira amawongolera bwino momwe zida zilizonse zingagwiritsidwe ntchito.

Kodi ubwino wa valve ya PVC ndi yotani?

Ntchito iliyonse imayang'anizana ndi zovuta za bajeti, koma simungathe kunyalanyaza kudalirika. Mavavu a PVC amawongolera bwino momwe zinthu zimaloleza.

Mavavu a PVC amapereka mtengo wosagonjetseka, kukhazikitsa kosavuta, komanso kukana kwa dzimbiri kwapamwamba poyerekeza ndi njira zina zachitsulo. Ndiwotsika mtengo 50-70% kuposa CPVC pomwe amapereka ntchito zabwino kwambiri pakugwiritsa ntchito madzi ozizira.

Kwa machitidwe amadzi ozizira, palibe mtengo wabwinoko kuposa PVC. Malumikizidwe awo osungunulira-owotcherera amapanga zolumikizana mwachangu, zodalirika kuposa zida zomangira zitsulo, zomwe zimachepetsa ndalama zogwirira ntchito. Mosiyana ndi zitsulo, siziwononga kapena kupanga mchere. Ku Pntek, tapanga zathuMavavu a PVCndi matupi olimbikitsidwa omwe amasunga umphumphu wawo ngakhale atagwiritsidwa ntchito kwa zaka zambiri. Kwa ma projekiti ngati Jacky'smachitidwe ulimi wothirirakumene kutentha sikudetsa nkhawa, PVC imakhalabe chisankho chanzeru kwambiri.

Chifukwa chiyani CPVC sikugwiritsidwanso ntchito?

Mutha kumva zonena kuti CPVC yayamba kutha, koma chowonadi ndi chosavuta. Kupititsa patsogolo zinthu sikunathetse ubwino wake wapadera.

CPVC imagwiritsidwabe ntchito kwambiri koma yasinthidwa ndi PEX ndi zida zina m'malo ena okhala chifukwa cha mtengo. Komabe, imakhalabe yofunikira pamakina amadzi otentha amalonda komwe kutentha kwake (93°C/200°F) kumaposa njira zina.

Ngakhale kuti PEX yayamba kutchuka pakupanga mapaipi apanyumba, CPVC imakhala ndi malo amphamvu m'magawo atatu ofunika:

1. Nyumba zamalonda zokhala ndi machitidwe apakati amadzi otentha
2. Ntchito zamafakitale zofunikakukana mankhwala
3. Retrofit mapulojekiti ofanana ndi maziko a CPVC omwe alipo

Muzochitika izi, kuthekera kwa CPVC kuthana ndi kutentha ndi kupanikizika popanda zitsulo zachitsulo kumapangitsa kuti zisalowe m'malo. Lingaliro loti izi zikusowa ndi zambiri zokhudzana ndi kusintha kwa msika wa nyumba kusiyana ndi kutha kwaukadaulo.

Kodi zolumikizira za PVC ndi CPVC zimagwirizana?

Zosakaniza zosakaniza zimawoneka ngati njira yachidule yophweka, koma kuphatikiza kosayenera kumapanga mfundo zofooka zomwe zimaika pangozi machitidwe onse.

Ayi, sizigwirizana mwachindunji. Ngakhale onsewa amagwiritsa ntchito kuwotcherera zosungunulira, amafunikira simenti zosiyanasiyana (simenti ya PVC siyimangirira bwino CPVC ndi mosemphanitsa). Komabe, zosinthira zosinthira zilipo kuti zilumikizidwe mosamala zida ziwirizi.

Kusiyanasiyana kwa mankhwala kumatanthauza kuti simenti zawo zosungunulira sizisinthana:

• Simenti ya PVC imasungunuka pamwamba pa PVC kuti igwirizane
• Simenti ya CPVC ndi yamphamvu kuwerengera kapangidwe kake kolimba

Kuyesera kukakamiza kugwirizanitsa kumabweretsa mafupa ofooka omwe amatha kuyesa mayesero poyamba koma amalephera pakapita nthawi. Ku Pntek, timalimbikitsa nthawi zonse:

1. Kugwiritsa ntchito simenti yoyenera pamtundu uliwonse wazinthu
2. Kuyika zokometsera zosinthira zoyenera ngati kulumikizana kuli kofunikira
3. Kulemba momveka bwino zigawo zonse kuti mupewe kusakanikirana

Mapeto

Ma valve a mpira a PVC ndi CPVC amagwira ntchito zosiyanasiyana koma zofunikanso chimodzimodzi-PVC yamadzi ozizira otsika mtengo komanso CPVC yofuna kugwiritsa ntchito madzi otentha. Kusankha moyenera kumapangitsa kuti ntchito ikhale yotetezeka komanso yokhalitsa. Nthawi zonse mufanane ndi valavu ndi kutentha kwadongosolo lanu ndi zofunikira za mankhwala kuti mupeze zotsatira zabwino.
