Masiku ano, pali njira zambiri zosangalatsa komanso zopanga zopangira mapaipi. Chimodzi mwazinthu zodziwika bwino zopangira mapaipi apanyumba masiku ano ndi PEX (Cross-Linked Polyethylene), makina opangira mipope komanso oyenerera omwe amatha kuyenda mozungulira pansi ndi pakhoma, koma olimba kuti apirire dzimbiri ndi madzi otentha. Mapaipi a PEX amamangiriridwa ku pulasitiki kapena zitsulo zomangira pakhoma mu dongosololi pomangirira m'malo momatira kapena kuwotcherera. Zikafika pa chitoliro cha PEX vs PVC yosinthika, chisankho chabwinoko ndi chiti?

Flexible PVC ndizomwe zimamveka. Ndi chitoliro chosinthika cha kukula kofanana ndi PVC wamba ndipo chimatha kumangirizidwa ku zida za PVC ndi simenti yosinthika ya PVC. PVC yosinthika nthawi zambiri imakhala yokulirapo kuposa chitoliro cha PEX chifukwa cha kukula kwake 40 ndi makulidwe a khoma. Werengani kuti mudziwe ngatiPEX chitoliro kapena PVC yosinthikandizabwino pakugwiritsa ntchito kwanu!

zinthu zopangira
Zida ziwirizi zimawoneka zofanana chifukwa cha kusinthasintha kwake, koma kapangidwe kake, kugwiritsa ntchito ndi kukhazikitsa ndizosiyana kwambiri. Tiyamba ndi kuyang'ana zinthu. PEX imayimira polyethylene yolumikizana ndi mtanda. Amapangidwa ndi polyethylene yapamwamba kwambiri yokhala ndi zomangira zolumikizirana pama polima. Zimamveka zovuta, koma zimangotanthauza kuti zinthuzo ndi zosinthika ndipo zimatha kupirira kupsinjika kwakukulu (mpaka 180F pakugwiritsa ntchito mapaipi).

PVC yosinthika imapangidwa kuchokera ku zomwezozinthu zofunika monga PVC wokhazikika: polyvinyl chloride. Komabe, mapulasitiki amawonjezeredwa kumagulu kuti azitha kusinthasintha. PVC yosinthika imatha kupirira kutentha kuchokera -10F mpaka 125F, kotero si yoyenera madzi otentha. Komabe, ndizothandiza kwambiri pazogwiritsa ntchito zingapo, zomwe tikambirana mgawo lotsatira.

ntchito
Kusiyanitsa pakati pa mapaipi awiriwa ndi aakulu kuposa mapangidwe awo. Amagwiritsidwanso ntchito mosiyana kwambiri. Chitoliro cha PEX chimagwiritsidwa ntchito kwambiri m'mapaipi apanyumba ndi ogulitsa chifukwa cha malo ake ochepa komanso kukana kutentha. PEX ndiyabwino pantchitozi chifukwa imatha kupindika ndikupindika kulikonse popanda kugwiritsa ntchito zida zambiri. Ndikosavuta kukhazikitsa kuposa mkuwa, womwe wakhala muyeso wamadzi otentha kwa mibadwomibadwo.

Chitoliro chosinthika cha PVC sichingagwire madzi otentha, koma chili ndi zabwino zina. Mapangidwe ake komanso kulimba kwamankhwala kumapangitsa kuti PVC ikhale yabwino pamadziwe ndi kuthirira. Klorini yogwiritsidwa ntchito popanga madzi a padziwe ilibe mphamvu pang'ono pa chitoliro cholimbachi. Flex PVC ndiyabwinonso pakuthirira m'munda, chifukwa imatha kuyendayenda kulikonse komwe mungafune popanda zida zambiri zokwiyitsa.

Monga mukuwonera, kuyerekeza chitoliro cha PEX ndi PVC yosinthika kuli ngati kuponya timu ya baseball motsutsana ndi timu ya hockey. Iwo ndi osiyana kwambiri moti sangathe ngakhale kupikisana wina ndi mzake! Komabe, uku sikutha kwa kusiyanako. Tiwona chimodzi mwazinthu zodziwika kwambiri zamtundu uliwonse wa chitoliro: kukhazikitsa. Werengani zambiri za mapulogalamu a PEX munkhaniyi kuchokera ku The Family Handyman.

Ikani
Nthawi ino tiyamba ndi PVC yosinthika, chifukwa imayikidwa m'njira yomwe timaidziwa bwino pa PVC Fittings Online. Chitolirocho chimakhala ndi zida zamtundu womwewo monga chitoliro cha PVC. Chifukwa ili ndi pafupifupi mankhwala ofanana ndi PVC wamba, PVC yosinthika imatha kulumikizidwa ndi kumangirizidwa kuzinthu za PVC. Simenti yapadera ya PVC yosinthika ikupezeka yomwe idapangidwa kuti ipirire kugwedezeka ndi kukanikiza komwe kumapezeka m'madziwe osambira ndi makina a spa.

ma pex, mphete za crimp ndi zida za crimp PEX mapaipi amagwiritsa ntchito njira yolumikizira yapadera. M'malo momatira kapena kuwotcherera, PEX imagwiritsa ntchito zitsulo zaminga kapena zopangira pulasitiki zomwe zimatalikirana kapena kuziyika pakhoma. Machubu apulasitiki amamangiriridwa ku malekezero amingawa pogwiritsa ntchito mphete zachitsulo, zomwe zimakhala ndi zida zapadera zopukutira. Pogwiritsa ntchito njirayi, kulumikizana kumatenga masekondi ochepa chabe. Pankhani ya mapaipi apanyumba, makina a PEX amatenga nthawi yocheperako kuyika kuposamkuwa kapena CPVC. Chithunzi chakumanja chikuwonetsa teti ya PEX yamitundu yambiri, mphete ya crimp yamkuwa, ndi chida cha crimp, zonse zomwe zikupezeka m'sitolo yathu!
