Umbhobho wokuFundisa kuMgangatho we-PEX vs Ubhedu / uMbhobho we-PE-RT

Kwinkqubo yobushushu obuphantsi obukhazimlayo bomgangatho ophantsi, imibhobho ifana nemithambo yegazi yomzimba womntu, echaphazela ngqo ukusebenza kakuhle kokufudumeza, ukusetyenziswa kwamandla kunye namava okusebenzisa ixesha elide. Ngokuqhubela phambili kobugcisa bezinto eziphathekayo, I-PEX (i-polyethylene edibeneyo) umbhobho, umbhobho wobhedu kunye ne-PE-RT (i-polyethylene yokumelana nobushushu obuphezulu) imibhobho ibe lukhetho oluqhelekileyo. Kweli nqaku, siya kuthelekisa imilinganiselo emine yeempawu zezinto eziphathekayo, ukumelana nomhlwa, Ukusebenza kakuhle kwe-thermal conductivity kunye neendleko zofakelo ukukunceda wenze izigqibo ezingabizi kakhulu.

Ekuqaleni, uthelekiso lwezinto: ukuba bhetyebhetye, ukhuseleko lobomi nokusingqongileyo

1.Umbhobho wokufudumeza umgangatho wePEX: ibhalansi yokuguquguquka kunye nokuqina ...

Imibhobho ye-PEX idityaniswe ngokunqamlezileyo ukwenza ubume bomnatha obumacala amathathu obudibanisa ukuguquguquka nokomelela kwepolyethylene.. Iinzuzo zayo ziquka:

• ...Dukumelana ne-eformation: -70℃ ~ 110 ℃ uluhlu lonyamezelo, unokuxhathisa umgangatho wokufudumeza umjikelo obandayo kunye nokutshatyalaliswa okushushu.
• ...Mukomelela kwengqondo: inokuphila ngokwayo emva kokwaphuka ngempazamo ngexesha lolwakhiwo ukunciphisa umngcipheko wokuvuza.
• Ukhuseleko lokusingqongileyo: akukho mngcipheko wemvula yentsimbi enzima, ngokuhambelana nomgangatho we-European Union RoHS.

2.Cumbhobho ongaphezulu: imida yombhobho yentsimbi yemveli ...

Umbhobho we-Copper uyaziwa ngokuba ne-thermal conductivity ephezulu, kodwa kukho iintsilelo ezicacileyo:

• ...Hubunzima, kunzima ukugoba: kufuneka inani elikhulu lamalungu, ukwandisa ukuvuza okunokwenzeka.
• Oi-xidation kunye ne-electrolytic corrosion: ngakumbi kwi-alkaline okanye amanzi anesulfure ekulula ukuvelisa ipatina.
• ...Cost-ubuthathaka: Ixabiso lemathiriyeli ekrwada lichaphazeleka kakhulu kukuguquguquka kwexabiso lobhedu kumazwe ngamazwe.

3.PE-RT ityhubhu: ukhetho oluphakathi lweendleko-esebenzayo ...

I-PE-RT kuphucula ukumelana nobushushu ngokuguqulwa kwesakhiwo seemolekyuli, kodwa xa kuthelekiswa nePEX:

• Weak ukumelana noxinzelelo: kulula ukukhasa phantsi kwexesha elide lobushushu obuphezulu, kunye nobomi bayo benkonzo malunga 20-30 iminyaka (I-PEX inokufikelela ngaphezulu 50 iminyaka).
• ...Linkqubo efanisiweyo: ilungele ngakumbi inkqubo yokufudumeza ubushushu obuphantsi ngaphantsi kwe-60℃.
• Ukuqukumbela: I-PEX iyaphumelela ebomini kunye nokuguquguquka, ngokukodwa ukulungelelaniswa kombhobho onzima.

Ukumelana nokubola: olona vavanyo lomgangatho wamanzi kunye nokusingqongileyo

ityhubhu yePEX: ukumkani we-inertia yekhemikhali

Akukho kusabela kwiasidi, isisombululo sealkali kunye netyuwa (pH 2-12), iiyoni zekloridi, akukho mfuneko yokucoca rhoqo.

Ityala: 90% yokufudumeza umgangatho kuMntla Yurophu isebenzisa imibhobho ye-PEX ukujongana namanzi aphantsi amaminerali aphezulu ngaphandle koxinzelelo.

Umbhobho wobhedu: indawo yemigodi yomngcipheko womhlwa ...

• Ei-lectrochemical corrosion: kulula ukwenza umphumo webhetri yendawo emanzini kunye nomxholo ophezulu we-oxygen.
• Sukubola kwe-ulfide: amanzi kwezinye iindawo zaseTshayina aphezulu kwisulfure, ekulula ukwenza isikali sobhedu sesulfide emnyama.
• Iindleko zokugcina: kufuneka ukongeza i-corrosion inhibitor rhoqo, iindleko zonyaka zokugcinwa malunga 300-500  /100㎡.

PE-RT ityhubhu: uzinzo lungaphantsi kwePEX...

Emva kokusetyenziswa kwexesha elide, inokubangela ukonakala ngenxa ye-oxidation, kwaye ikhonkco kulula ukuqhekeka.

Ukuqukumbela: I-PEX iphantse yangalungiswa, ingakumbi ilungele imekobume yomgangatho wamanzi eTshayina.

I-Thermal conductivity Efficiency: Ukungaqondwa “inzuzo yesinyithi”

1.Dokanye uthelekiso

2.Metal thermal conductivity ≠ eyona inzuzo ...

• Thermal inertia: umbhobho wobhedu unokugcinwa kobushushu obuqinileyo, okukhokelela ekunyukeni kancinci kobushushu/ukupholisa, engabangeli ulawulo oluchanekileyo lobushushu.
• Okususwa kukulahlekelwa bubushushu: ityhubhu yobhedu idinga ukufakwa okongeziweyo (20% iindleko ezingaphezulu), kwaye i-PEX ine-conductivity ephantsi ye-thermal.
• Uniformity: Iityhubhu ze-PEX zinokudityaniswa-zibotshelelwe ukuhlawulela umahluko we-thermal conductivity kunye nokufezekisa ukulahla ubushushu obulinganayo..
• Ukuqukumbela: Umphumo wangempela wokufudumeza we-PEX usondele kwityhubhu yethusi, kwaye ugcino lwamandla luphuculwe ngo 10%-15%.

Iindleko zokufakela: ikhowudi yokugcina imali kwiiprojekthi ezifihliweyo

Cuthelekiso lweendleko ezipheleleyo (ukuthatha 100㎡ indlu njengomzekelo) ...

Izibonelelo zokwakha zePEX ...

• ...Sumbhobho ongeyodwa ubeka ngokuqhubekayo: akukho uyilo oludibeneyo lokunciphisa 90% iindawo zokuvuza.
• Toool ukwenza lula: isixhobo esikhethekileyo sokudibanisa endaweni ye-welding yobhedu yombhobho, nciphisa ixesha lokwakha nge 40%.
• Hukunyamezela iimpazamo: inkxaso non-professional DIY ukulungiswa (njengokusetyenziswa komkhono oshushu onyibilikayo).
• Ukuqukumbela: Iindleko ezibanzi zePEX kuphela 1/3 yalowo wombhobho wobhedu, kwaye ulondolozo lwamva luphantse lube yi-zero investment.

Ukhetho lokugqibela: Kutheni i-PEX inguMkhwa wexesha elizayo?

1.Iindlela ezivela kwidatha yoshishino ...

I-PEX iya kuphendula 68% kwimarike yombhobho wokufudumeza umgangatho wehlabathi kwi 2025 (umthombo wedatha: Ingxelo ye-GIA).

Izinga lokwamkelwa kwe-PEX kwiinkqubo zokufudumeza ezisanda kufakwa kwindawo yokuhlala e-China liye latsiba ukusuka 32% kwi 2015 ukuya 79% kwi 2025.

2.Scenario-based kucetyiswa ...

I-PEX ekhethwayo: ifanelekile 90% yeentsapho, ngakumbi ukuguqulwa kwezindlu ezindala kunye neeyunithi ezinzima.

Khetha ngokucophelela umbhobho wobhedu: Ikhuthazwa kuphela kwiindawo zorhwebo (ezifana neendawo zokujima) nge-UHF qala kwaye umise, kunye nenkqubo yamanzi athambileyo iyafuneka.

Enye indlela ye-PE-RT: imimandla esemazantsi enohlahlo lwabiwo-mali olulinganiselwe kakhulu kunye namaxesha amafutshane okufudumeza.

Ubume obuphindaphindayo bombhobho wokufudumeza phantsi komgangatho kuphuculo lwexabiso lomsebenzisi — I-PEX ifezekisa ukuthembeka okuphezulu ngexabiso eliphantsi, oluyindibaniselwano egqibeleleyo yezinto zenzululwazi kunye nobulumko bobunjineli.
