Masiku ano, pali njira zambiri zosangalatsa komanso zopanga mapaipi. Chimodzi mwa zipangizo zodziwika bwino za mapaipi apakhomo masiku ano ndi PEX (Cross-Linked Polyethylene), njira yolumikizira mapaipi ndi yolumikizira yomwe imasinthasintha mokwanira kuti idutse pansi ndi pakhoma, koma yolimba mokwanira kuti ipirire dzimbiri ndi madzi otentha. Mapaipi a PEX amamangiriridwa ku zolumikizira zapulasitiki kapena zitsulo pa hub mu dongosololi mwa kukumba m'malo momangirira guluu kapena kuwotcherera. Ponena za chitoliro cha PEX vs PVC yosinthasintha, ndi chisankho chiti chabwino?

PVC yosinthasintha ndi momwe imamvekera. Ndi chinthu chosavuta kugwiritsa ntchito.chitoliro chosinthasintha cha kukula kofanana ndi PVC wambandipo ikhoza kulumikizidwa ku zolumikizira za PVC ndi simenti yosinthasintha ya PVC. PVC yosinthasintha nthawi zambiri imakhala yokhuthala kwambiri kuposa chitoliro cha PEX chifukwa cha kukula kwake kwa 40 ndi makulidwe a khoma. Pitirizani kuwerenga kuti mudziwe ngati chitoliro cha PEX kapena PVC yosinthasintha ndi yabwino kugwiritsa ntchito!

chopangira zinthu
Zipangizo ziwirizi zimaoneka zofanana chifukwa cha mawonekedwe ake osinthasintha, koma kapangidwe kake, kugwiritsa ntchito kwake ndi kuyika kwake n'kosiyana kwambiri. Tiyamba ndi kuyang'ana zinthuzo. PEX imayimira polyethylene yolumikizidwa. Imapangidwa ndi polyethylene yolimba kwambiri yokhala ndi ma bond olumikizidwa mu kapangidwe ka polima. Zimamveka zovuta, koma zimangotanthauza kuti zinthuzo ndi zosinthasintha ndipo zimatha kupirira kupsinjika kwakukulu (mpaka 180F pakugwiritsa ntchito mapaipi).

PVC yosinthasintha imapangidwa kuchokera ku zinthu zofanana ndi PVC wamba: polyvinyl chloride. Komabe, mapulasitiki amawonjezedwa ku chinthucho kuti chikhale chosinthasintha. PVC yosinthasintha imatha kupirira kutentha kuyambira -10F mpaka 125F, kotero siyoyenera kuyikidwa m'madzi otentha. Komabe, ndi yothandiza kwambiri pa ntchito zingapo, zomwe tidzakambirana m'gawo lotsatira.

ntchito
Kusiyana pakati pa mapaipi awiriwa ndi kwakukulu kuposa kapangidwe kake. Amagwiritsidwanso ntchito m'njira zosiyanasiyana. Chitoliro cha PEX chimagwiritsidwa ntchito kwambiri m'mapayipi apakhomo ndi amalonda chifukwa cha malo ochepa komanso kukana kutentha kwambiri. PEX ndi yoyenera ntchito izi chifukwa imatha kupindika mosavuta mbali iliyonse popanda kugwiritsa ntchito zowonjezera zambiri. N'zosavuta kuyika kuposa mkuwa, womwe wakhala muyezo wa madzi otentha kwa mibadwomibadwo.

Chitoliro cha PVC chosinthasintha sichingagwire madzi otentha, koma chili ndi ubwino wina. Kulimba kwake ndi kapangidwe kake kumapangitsa PVC yosinthasintha kukhala yabwino kwambiri pa maiwe ndi kuthirira. Chlorine yomwe imagwiritsidwa ntchito pamadzi a dziwe siikhudza kwambiri chitoliro cholimba ichi. PVC yosinthasintha ndi yabwinonso pothirira m'munda, chifukwa imatha kuyendayenda kulikonse komwe mukufuna popanda zowonjezera zambiri zokhumudwitsa.

Monga mukuonera, kufananiza chitoliro cha PEX ndi PVC yosinthasintha kuli ngati kupikisana ndi gulu la baseball motsutsana ndi gulu la hockey. Ndi osiyana kwambiri, sangathe ngakhale kupikisana wina ndi mnzake! Komabe, apa si pomwe kusiyana kumathera. Tiona chimodzi mwazinthu zofunika kwambiri za mtundu uliwonse wa chitoliro: kukhazikitsa. Werengani zambiri za mapulogalamu a PEX m'nkhaniyi kuchokera ku The Family Handyman.

Ikani
Nthawi ino tiyamba ndi PVC yosinthasintha, chifukwa imayikidwa m'njira yomwe timaidziwa bwino ku PVC Fittings Online. Chitolirocho chili ndi mtundu womwewo wazolumikizira monga chitoliro cha PVC chachizoloweziPopeza ili ndi kapangidwe ka mankhwala kofanana ndi PVC wamba, PVC yosinthasintha imatha kukonzedwa ndikusimidwa ndi PVC fittings. Simenti yapadera yosinthasintha ya PVC ilipo yomwe idapangidwa kuti ipirire kugwedezeka ndi kupsinjika komwe kumapezeka m'madziwe osambira ndi m'malo osambira.

Ma pex tee, mphete zopindika ndi zida zopindika Mapaipi a PEX amagwiritsa ntchito njira yapadera yolumikizira. M'malo mwa guluu kapena kuwotcherera, PEX imagwiritsa ntchito zitsulo zopindika kapena zolumikizira zapulasitiki zomwe zimayikidwa patali kapena kuyikidwa pa hub. Machubu apulasitiki amamangiriridwa ku malekezero a zitsulo zopindika pogwiritsa ntchito mphete zopindika zachitsulo, zomwe zimapindika ndi zida zapadera zopindika. Pogwiritsa ntchito njira iyi, kulumikizana kumatenga masekondi ochepa okha. Ponena za mapaipi apanyumba, makina a PEX amatenga nthawi yochepa kuyika kuposamkuwa kapena CPVCChithunzi chomwe chili kumanja chikuwonetsa t-sheti ya polyalloy PEX, mphete ya crimp yamkuwa, ndi chida cha crimp, zonse zikupezeka m'sitolo yathu!
