Kodi mukuda nkhawa ndi kulephera kwa makina anu pa ntchito zanu za mapaipi? Kusankha zinthu zolakwika kungayambitse kutaya madzi ambiri, kukonza zinthu modula, komanso kuwononga mbiri yanu.

Cholumikizira cha PPR ndi cholumikizira chopangidwa kuchokera ku Polypropylene Random Copolymer. Zolumikizira izi zimagwiritsidwa ntchito ndi mapaipi a PPR ndipo zimalumikizidwa kudzera mu njira yolumikizira kutentha, yomwe imalumikiza bwino chitolirocho ndikuchiyika mu chidutswa chimodzi, chopanda msoko, komanso chosataya madzi kwamuyaya.

Monga munthu amene wamanga bizinesi yake popereka njira zodalirika zoyendetsera madzi, ndikumvetsa kufunika kwa zinthu zomwe mungadalire. Woyang'anira zogula ngati Carlos sakungogula gawo lake, koma akugula mtendere wamumtima kwa makasitomala ake. Tiyeni tiwone chifukwa chake PPR yakhala njira yodziwika bwino yopangira mapaipi amakono.

Kodi zolumikizira za PPR zimagwiritsidwa ntchito pa chiyani?

Kodi mukuyika makina opopera madzi omwe amafunika kunyamula madzi otentha ndi ozizira? Kugwiritsa ntchito zipangizo zomwe sizili ndi kutentha kwambiri ndi vuto lalikulu lomwe likuyembekezera kuchitika.

Zipangizo za PPR zimagwiritsidwa ntchito makamaka pamakina amadzi otentha ndi ozizira m'nyumba, mahotela, zipatala, ndi maofesi. Kukana kwawo mankhwala komanso kulimba kwawo kumapangitsanso kuti zikhale zoyenera kunyamula madzi m'mafakitale, makina oponderezedwa mpweya, komanso kusonkhanitsa madzi amvula.

Ndikukumbukira ndikulankhula ndi kontrakitala ku Mexico yemwe ankamanga hotelo yatsopano. Ankada nkhawa ndi ndalama zosamalira kwa nthawi yayitali chifukwa cha kutuluka kwa madzi mkati mwa makoma. Ndinafotokoza momwe malo olumikizirana a PPR amachotsera chiopsezochi. Kwa manejala wogula ngati Carlos, kukhala ndi mwayi wopereka chitetezo champhamvu ndi mfundo yogulitsa. Zimasintha zokambirana kuchoka pamtengo kupita pamtengo wanthawi yayitali.

Mapaipi a Nyumba ndi Mabizinesi

Iyi ndi njira yoyamba kugwiritsa ntchito. PPR siiwononga kapena kulola limescale kusonkhana, zomwe zikutanthauza kuti madzi azikhala ndi mphamvu komanso kuyenda bwino nthawi yonse ya dongosololi. Zipangizozi sizowopsa ndipo zimavomerezedwa kuti zigwiritsidwe ntchito pamadzi akumwa, zomwe zimaonetsetsa kuti ogwiritsa ntchito ali ndi thanzi komanso chitetezo. Kwa akatswiri okonza mapaipi, makina omwe sapanga ma callback okhudzana ndi kutuluka kwa madzi ndi agolide weniweni.

HVAC ndi Machitidwe a Mpweya Wopanikizika

Mu makina otenthetsera, mpweya wabwino, ndi oziziritsa mpweya (HVAC),Mapaipi a PPRamagwiritsidwa ntchito kunyamula madzi ozizira kapena otentha. Malo awo osalala amkati amachepetsa kukangana, zomwe zimapangitsa kuti mphamvu zizigwiritsidwa ntchito bwino. Pa mpweya wopanikizika,chilengedwe chosataya madziKutulutsa madzi mumzere woponderezedwa wa mpweya ndi ubwino waukulu. Kutulutsa madzi mumzere woponderezedwa wa mpweya kumawononga ndalama zambiri, kotero dongosolo lotetezeka limapereka ndalama zambiri zogwirira ntchito.

Kugwiritsa Ntchito Mafakitale ndi Ulimi

Popeza PPR imagonjetsedwa ndi mankhwala osiyanasiyana, ndi njira yodalirika yotumizira madzi osiyanasiyana m'mafakitale. Mu ulimi, ingagwiritsidwe ntchito pothirira m'malo obiriwira, makamaka komwe feteleza amasakanizidwa m'madzi, zomwe zimapangitsa kuti mapaipi achitsulo azizire mwachangu.

Ndi iti yabwino, PPR kapena PEX?

Kodi mkangano pakati pa kulimba kwa PPR ndi kusinthasintha kwa PEX ukubweretsa chisokonezo? Kusankha cholakwika kungayambitse ndalama zambiri zoyikira ndi machitidwe omwe sagwira ntchito monga momwe amayembekezera.

Palibe chilichonse mwa izi chomwe chili chabwino kuposa china chilichonse; chimakwaniritsa zosowa zosiyana. PPR imapereka mapaipi olimba, owongoka komanso malo olumikizirana amphamvu kwambiri otenthedwa. PEX ndi yosinthasintha kwambiri, zomwe zimapangitsa kuti kuyika mwachangu kuzungulira zopinga ndi zolumikizira zochepa. Kusankha kwabwino kwambiri kumadalira zomwe polojekitiyi ikufuna komanso zomwe okhazikitsa amazolowera.

Nthawi zambiri ndimalangiza makasitomala kuti aganizire za nthawi yayitali. Munthu wina wokonza mapaipi anandiuzapo kuti amakonda PPR pamapulojekiti apamwamba okhalamo chifukwa mizere yolimba imawoneka yaukadaulo kwambiri ndipo malo olumikizirana amamva kuti ndi otetezeka kwambiri kwa iye. Ngakhale kuti PEX ndi yofulumira kuyiyika, amagulitsa makasitomala ake chifukwa cha kudalirika kwa PPR. Kwa Carlos, akupereka njira zonse ziwiri kuti athe kuthandiza makontrakitala omwe amaika patsogolo liwiro ndi omwe amaika patsogolo kulimba.

Tebulo ili likuthandiza kufotokozera momveka bwino kuti chisankhocho ndi chosiyana. Ngati ntchitoyo ikufuna kugwirira ntchito kwautali komanso molunjika pakupanga kwatsopano, kulimba kwa PPR ndi mphamvu ya malumikizano ndizabwino kwambiri. Ngati ndi kukonzanso komwe kuli ndi ngodya zambiri zolimba komanso zomangamanga zomwe zilipo kale, kusinthasintha kwa PEX kungapulumutse nthawi ndi ntchito yambiri.

Kodi vuto la PPR ndi chiyani?

Kodi mukuganiza kuti PPR ndi njira yabwino kwambiri yothetsera mavuto anu onse? Musanapereke, muyenera kudziwa zofooka zake kuti mupewe mavuto okhumudwitsa komanso okwera mtengo panthawi yokhazikitsa.

Zoyipa zazikulu za PPR ndi kulimba kwake, komwe kumafuna zolumikizira zambiri kuti zizungulire, kufunikira kwa chida chapadera cholumikizira kutentha, komanso kukula kwake kolunjika ponyamula madzi otentha. Sizimalimbananso ndi kuwala kwa UV ndipo ziyenera kutetezedwa ku dzuwa.

Kulankhula momveka bwino za zofooka za chinthu ndikofunika kwambiri kuti munthu akhale ndi chidaliro. Nthawi zonse ndimaonetsetsa kuti ogwirizana nawo ngati Carlos akudziwa bwino zinthu izi. Kuthana ndi zovuta izi n'kosavuta pokonzekera bwino, ndipo zimasonyeza kuti wokhazikitsayo ndi katswiri weniweni. Mwachitsanzo, kudziwa kuphatikiza chingwe chokulitsa chingwe chamadzi otentha ndi chizindikiro cha kukhazikitsa kwabwino.

Zida Zapadera ndi Maphunziro

Simungathe kulumikiza PPR ndi guluu kapena zida zosavuta kugwiritsa ntchito pamanja. Zimafunikachitsulo chowotcherera kutenthaNgakhale kuti si yokwera mtengo kwambiri, ndi ndalama zomwe zimafunika pasadakhale kwa kontrakitala aliyense kuyambira ndi PPR. Kuphatikiza apo, wogwiritsa ntchito amafunika maphunziro oyambira kuti adziwe nthawi yayitali yotenthetsera chitoliro ndi kuyika kuti apange weld yoyenera. "Weld yozizira" yomwe sinalumikizidwe mokwanira ingayambitse kulephera.

Kulimba ndi Kukula kwa Kutentha

Ngakhale kulimba ndi phindu la kuthamanga molunjika, ndi vuto poyenda m'malo opapatiza. Kusintha kulikonse komwe kumafuna kulumikizidwa ndi chigongono. Chofunika kwambiri, monga mapulasitiki onse, PPR imakula ndi kutentha. Pakuyenda kwakutali kwa chitoliro cha madzi otentha, "lupu yowonjezera" kapena offset iyenera kupangidwa mu dongosolo kuti itenge kayendedwe kameneka ndikuletsa kupsinjika pa chitoliro ndi zolumikizira.

Kuzindikira kwa UV

PPR sinapangidwe kuti iwonekere padzuwa mwachindunji. Kuwala kwa ultraviolet kudzawononga zinthuzo pakapita nthawi, zomwe zimapangitsa kuti zikhale zofooka. Kuyika kulikonse kwa panja kwa chitoliro cha PPR kuyenera kupakidwa utoto wowala,Utoto wotchinga UVkapena yokutidwa ndi chikwama choteteza. Iyi ndi sitepe yosavuta koma yofunika kwambiri yomwe siinganyalanyazidwe.

Kodi zomangira za PPR ndizabwino kuposa PVC?

Kodi mumayesa kugwiritsa ntchito PVC yokhazikika pa waya wothira madzi otentha kuti musunge ndalama? Ichi ndi cholakwika choopsa chomwe chingayambitse kulephera kwa mapaipi, kuwonongeka kwa katundu, komanso mavuto okhudzana ndi udindo.

Pakugwiritsa ntchito madzi otentha, PPR ndi yabwino kuposa PVC. PPR idapangidwa kuti igwire kutentha mpaka 95°C (203°F), pomwe PVC yokhazikika imatha kuyamba kufewa ndikuwonongeka pafupifupi 60°C (140°F), zomwe zimapangitsa kuti ikhale yosayenera komanso yosatetezeka ku madzi otentha.

Monga mtsogoleri wa Pntek, kampani yotchuka ndi zinthu zake zabwino za PVC, ndine woyamba kunena kuti: gwiritsani ntchito chida choyenera pa ntchito yoyenera. Timagulitsa PVC pa zinthu zomwe imachita bwino kwambiri—mipope yamadzi ozizira, kuthirira, ndi kukhetsa madzi. Kuyesa kuipangitsa kuti igwire ntchito yomwe sinapangidwe ndi njira yoti ilephereke. Pa bizinesi yake, Carlos amatumikira makasitomala ake bwino kwambiri poika PVC kuti igwiritsidwe ntchito m'madzi ozizira ndi PPR kuti igwiritsidwe ntchito m'madzi otentha.

Kuyerekeza Kumene Kuli Kofunika

Kusankha pakati pa PPR ndi PVC sikuti ndi chiyani "chabwino" chonse, koma ndi chiyani choyenera kugwiritsa ntchito. Nthawi zambiri zimatengera kutentha.
