Kuyini fibre polypropylene kwagcizelela? Okuhlezi emqondweni polypropylene amapayipi: ngebuhle nebubi

Kwamanzi, amalahle indlu noma ifulethi (yama yodwa noma eyodwa) ngeke akwenze ngaphandle ukusetshenziswa amapayipi. Abaningi khumbula ukuthi ukubheka alithandeki metal amapayipi, kufanele kube njalo ngesineke, azigcine zisebenza kahle, namanje nganoma isiphi isikhathi bakwazi ukuthatha umninindlu, ngoba ngokuhamba kwesikhathi zisabela lapho kushintsha izinga lokushisa nokucindezelwa sibi kakhulu.

Metal kuhle okusheshayo ngaphakathi embozwe isikali, okuyinto kakhulu kubambezela ukuhanjiswa amanzi ashisayo, futhi ngenxa yalokho, kunciphisa ukudluliswa ukushisa. Mhlawumbe, zonke nemibi metal amapayipi utshelwa ososayensi, onjiniyela kanye technologists ukuthuthukisa futhi ukwethula onobuhle ezintsha amapayipi ezenziwe ngezinto zanamuhla besebenzisa ubuchwepheshe eziphambili.

Namuhla, polypropylene amapayipi akusona isimanga. Babé ingxenye yokuphila kwethu kwansuku zonke, futhi cishe ngeke uthole wayenomuzi ofuna ukushintsha metal amapayipi ubudala entsha efanayo.

Izinzuzo izinto ezintsha

polypropylene Okuhlezi emqondweni - material yesimanje zobuchwepheshe, eye yasetshenziswa ngempumelelo enkulu ekwakhekeni amapayipi. Kulula kakhulu metal, libhekene kuyaqina namakhemikhali okusezingeni eliphezulu futhi ukugqwala ukumelana. Ngaphezu kwalokho, izinto iphephile imvelo.

Inqawe eyenziwe polypropylene kwagcizelela abe izindleko sasivumela ongaphakeme, futhi ukufakwa yabo akunzima kakhulu, ngisho non-ochwepheshe. Kufanele kuqashelwe ukuthi imizila le nto ezikhangayo ababukeka kakhulu alivamile avuzayo. Lokhu enkingeni kungenzeka kuphela ngenxa amaphutha enziwa phakathi nokufaka.

Ngaphezu kwalokho Ukushisa intrahouse izinhlelo futhi amapayipi amanzi kwagcizelela polypropylene elisetshenziswa amapayipi izinhlelo, ukupholisa zangaphandle amanzi, kwezolimo nasezimbonini. Zimbili izinhlobo yalesi material. Ngebuhle nebubi ngamunye wabo sizobe ukumboza kulesi sihloko.

izinhlobo

Polypropylene kuyinto noplastiki Coefficient okusezingeni eliphezulu lokwanda ezishisayo. lokushisa yayo ukuncibilika kuyinto +175 ° C. Nokho, sekuvele kwayithambisa okushisa aphansi (+140 ° C). A ipayipi wenza kusuka izinto ezinjalo ngeke ziqinisekiswe emsebenzini ezingeni lokushisa hhayi ephakeme kunaleyo +95 ° C.

Ngenxa yalokho ephezulu ingcindezi amanzi ashisayo futhi kungase likhubazeke. Ukuze kwandiswe amandla futhi ukunciphisa izinga ukunwetshwa komugqa amapayipi eyenziwe le nto, basuke luqiniswe ingilazi fibre noma aluminium. Ukuqinisa - kungcono nje uhlobo luhlaka eqinile okuyinto akuvumeli ipayipi ukwandisa noma ubude noma ububanzi. Ukuze uqhathanise, zicabange okuza of lwento ukunwetshwa ezishisayo we amapayipi ngaphambi nangemva ukuqinisa:

• polypropylene unreinforced - 0.15 mm / MK, mayelana 10 mm kuya ku-1 imitha ezingeni lokushisa 70 ° C;
• aluminium kwagcizelela - 0.03 mm / MK, kuya ku-3 mm imitha ngalinye;
• fiberglass ukuqinisa - 0,035 mm / MK.

Polypropylene fibre kwagcizelela

Indaba oluyinhlanganisela emithathu ungqimba. It isilinganiso fibre ungqimba ashiselwe kuya eduze polypropylene izingqimba. Imiphumela iba yinhlanganisela yokukhandleka ukwakhiwa eziqinile kakhulu kokuba Coefficient aphansi kakhulu lokwanda ezishisayo ziqhathaniswa sokuqala impahla. Ngenxa propylene Monolithic, fiberglass-kwagcizelela, abahlukene.

Inqawe ekhiqizwa kulokhu kwaziswa, abe kuyaqina okukhulu. Lokhu kunikeza nezimo of imikhiqizo, okuyinto lula kakhulu ukufakwa. Encishisiwe ukufakwa nesikhathi ukwakhiwa, njengasekuqaleni Welding amapayipi enjalo akudingeki oyi-bahlanza aluminium ungqimba.

Polypropylene kwagcizelela aluminiyamu

Kulokhu, lo ukugcizelela wenziwe a perforated noma okuqinile aluminium ucwecwe ukushuba 0.1 kuya 0.5 mm. A ucwecwe ngaphakathi nangaphandle phakathi laphakathi plastic. Izinhla zihlangene nge glue ekhethekile. Lapho ucwecwe abukeka ngayo ngaphandle, ngaphansi mncane ungqimba zokuhlobisa plastic, Welding aso kufaneleka is bahlanza nge ungqimba aluminium ukuze ugweme ukuxhumana metal ngamanzi futhi unikeze izinga Welding ezinhle ukuze ugweme ukuvuza.

Solid ucwecwe ungqimba ayikuvumeli-mpilo agelezele kokupholisayo. Inani lakhe ngokweqile kuvame ukuholela ukugqwala Ukushisa amadivaysi. Nokho, ucwecwe, esesikhundleni surface bushelelezi ngokuphelele, kungase kungasheleli ngaso sonke unikeze isibopho sasivumela obuqinile plastic. Ngenxa yale njongo a ingcina ekhethekile futhi kudinga bawuhloniphe inqubo, kungenjalo amangqamuzana amanzi angena ngokusebenzisa izindonga, buthelela ngaphansi ungqimba aluminium phezu futhi bangase bafinyelele amabhamuza.

Ngakho kwagcizelela polypropylene, aluminium ikhiqizwa usebenzisa ucwecwe perforated eminyakeni yamuva. It has izimbobo, ngesikhala esilinganayo. izingqimba plastic kulokhu kuthiwa esigaxe ndawonye ngokuphephile. Oxygen permeability e isakhiwo ucingo ngale ndlela kwandisa kancane, kodwa uhlala ngaphakathi uhla evamile.

Eminyakeni yamuva, amapayipi, lapho isendlalelo aluminium ibekwe phakathi ezimbili zamatshe plastic. Le ndlela umkhiqizo ihlinzeka ophansi umoya-mpilo permeability kanye ongaphakeme ukunwetshwa Coefficient. Abanye abakhiqizi zithi amapayipi enjalo angadingi pre-bula. Nokho, installers, ochwepheshe bakholelwa ukuthi ukuze kuqinisekiswe izinga ezinhle Welding, kufanele ngombala. Kungenjalo, ungqimba aluminium nabo amanzi, futhi ekugcineni le kuzokwenza ukugqwala metal nokwakhiwa umqulu. Pipe polypropylene kwagcizelela aluminium facer nge Imibhobho esemzimbeni ekhethekile bayamba.

Ukushisa

polypropylene Okuhlezi emqondweni Ukushisa (ngokunembile, amapayipi wenza kulokhu kwaziswa) - yafika kukhulu, okuyinto ethandwa kakhulu phakathi abanikazi ekhaya. Bona ingafakwa esakhiweni sokuhlala, nemikhakha ezimele.

Yikuphi ukukhetha ipayipi Ukushisa?

Namuhla esetshenziswa ezimbili izinhlobo amapayipi Ukushisa, okuyinto aqukethe izingqimba amathathu noma amahlanu. Leli payipi emithathu ungqimba sigcizelelwa ungqimba maphakathi. It zingenziwa aluminiyamu noma-fiberglass. Ngandlela-thile ngendlela ehlukile ahlelwe ezinhlanu-ungqimba amaphayiphi bafudumale. polypropylene Okuhlezi emqondweni isetshenziswa izingqimba ezimbili - i-yangaphandle futhi kwangaphakathi. Ngaphezu kwalokho, kukhona ugqinsi ingilazi (noma ucwecwe) kanye ezimbili ungqimba kokokunamathisela ukushisa ukumelana.

Mshini kanye nezimpawu

Zonke amapayipi ibhalwe zomzimba ziyinkimbinkimbi ngendlela abizwa osetshenziswayo nezinombolo ezikuvumela ukucacisa ukuthi kwathiwa kwenziwe ukuqinisa impahla. Pipe eyenziwe polypropylene kwagcizelela aluminium esinelebuli izifinyezo PPR-AL-PPR. Le mikhiqizo zihlukaniswe amaqembu amaningana:

• aluminium perforated imaphakathi nasemaceleni lesi sendlalelo zitholakala emhlabeni izimbobo ezincane;
• okuqinile aluminium ukuqinisa (ngaphandle izimbobo);
• emihlanu-ungqimba tube.

Aluminium (kwagcizelela) ungqimba kungase kudingeke Umbala ezahlukene. Njengomthetho, ke ongaqhubeki ukwaziswa mayelana nezinhlamvu kanye nekhwalithi yomkhiqizo, ngakho ungadikibali ke ukunakwa kakhulu lapho uthenga.

Kwenzeka ukuthi wokugubha esikhundleni ukuqokwa at PPR PEX. Lokhu kusikisela eziningi izakhiwo ezahlukene izingqimba. Inishiyali e inhlanganisela enjalo ngoba olwelwesini, kulandele aluminium abuye acedzele ekubizweni isendlalelo kwangaphakathi.

Okumbi ukuqinisa aluminiyamu

Leli payipi nokuba ukuqinisa zangaphandle, zithandwa kakhulu ngenxa intengo zabo okungabizi. Kodwa babe nobubi obuthile. Ukufakwa idinga ilungiswe aluminium kuhla kwakwakhe nge ubude efanelekayo. Ngaphezu kwalokho, uma ufaka noma iyiphi ukusebenza olungalungile e amashubhu ezinjalo kungalimaza yangaphandle ungqimba gcizelela, okuyinto kamuva nomthelela isimo lobuchwepheshe isakhiwo.

Pipe eyenziwe polypropylene kwagcizelela aluminium ngaphakathi, okuhlala isikhathi eside. Akudingi ukulungiselela eziyinkimbinkimbi yokumiswa. Kodwa kubalulekile ukuba acabangele ngesinye isici uxhumano - I-ukuvuvukala okunokwethenjelwa futhi obukhulu kufanele kube qualitatively enze ilungiswe imiphetho imininingwane, ngamanye amazwi, lo cross-ingxenye ipayipi kufanele abe bushelelezi futhi ngokuqinile mpo, kungenjalo uxhumano ngesikhatsi operation samanje akukho lezimanga. Emva uhlelo Ukushisa ugcwele, lokhu kucindezela kuzokwanda ngawakhamela amanzi ngisho ngokusebenzisa izikhala kulencane.

Inqawe nge glass fibre ukugcizelela

Le mikhiqizo ibhalwe - PPR-FB-PPR. Lokhu kusho ukuthi zenziwa ngumuntu multilayer, lapho ungqimba kwagcizelela (ingilazi Imicu yotshani) esikhungweni. Ngokuvamile, amapayipi zokuphumula ezinjalo zibizwa ngokuthi fiberglass. Njengoba ungqimba ucwecwe, ungqimba ingilazi Imicu yotshani kungenzeka anemibala ehlukene. On engxenyeni ipayipi kuyacaca kahle. Kodwa kulokhu, umbala akuyona inkomba yokuthi izinga noma nokunye ukucacisa futhi akuphazamisi ukusebenza.

Ochwepheshe abaningi bakholelwa ukuthi ingilazi-kwagcizelela polypropylene, Ukushisa - ikhambi ekahle. Inzuzo enkulu amashubhu esinjalo ukufakwa elula futhi esheshayo, bona angadingi Samandla futhi yokuhlanza. Ngale ndlela ungagcina isikhathi esiningi. Pipe eyenziwe polypropylene luqiniswe ingilazi endwangwini, delaminate ngoba isakhiwo Monolithic: ingilazi nje soldered kuya polypropylene.

Naphezu kweqiniso lokuthi Abenzi zithi amapayipi enjalo abanaso nhlobo amaphutha, zingabantu kancane disingenuous. Ngu izindawo obuthaka amapayipi ezinjalo zingase zihlanganise ukunwetshwa kancane mkhulu phakathi Ukushisa, uma iqhathaniswa amapayipi aluminium nakakhulu. Nokho, ngokuvumelana ze, lena akuyona lokususa kubalulekile wale mikhiqizo, futhi ezidume ezingaphezu kuka ipayipi nge isendlalelo aluminium.

I diameters we amapayipi

Ngakho, ukwakha alondoloze nemithombo yamanzi noma bafudumale system ukhetha polypropylene nakakhulu. I diameters kuzo ngemibhobho ubukhulu udinga kulesi simo? Abakhiqizi iveza kwagcizelela amapayipi e eziningi ezihlukahlukene kusukela 16 kuya 1200 mm ububanzi. Nokho, i-yasekhaya kwamanzi nokuthuthwa amapayipi kodwa angabangi umsindo asetshenziswa kusukela 16 kuya 32 mm, ukuze amapayipi okuhambisa indle (kwangaphakathi) - 40, 50 noma 110 mm ububanzi. Umhlangano omkhulu kunayo yonke polypropylene amapayipi asetshenziselwa ukufakwa amapayipi amapayipi ngaphandle kwe emafulethini, ngisho lonke omakhelwane.

Ukuze amanzi abandayo ukukhethwa yokuhlala ubukhulu ipayipi incike lemali amanzi amaphuzu, futhi ubude iphayiphi. Ngokuvamile, ipayipi okuphakelayo has a ububanzi of 32 mm ngokubukeka wiring ku ubukhulu flat yangaphandle zokhahlamba kusuka 16 kuya ku-20 mm.

izingxenye-accessory

Lapho obandayo kwagcizelela polypropylene amashubhu usebenzisa izakhi ezahlukene okwenyanga sokuqedela uxhumano. Bonke bazimisele kusengaphambili Ukushisa umdwebo wiring noma amapayipi. Le mininingwane ayadingeka: nokufakwa, Tees, izindololwane futhi couplings, nokufakwa nokunye. Basuke akhethiwe kuye ngokuthi ububanzi amashubhu kanye nezici zabo. Ngokwesibonelo, akunakwenzeka ukuthola ukufakwa kule izingxenye Ukushisa wesifunda ngamanzi abandayo.

Ukuxhuma namanye ezindaweni kohlelo, eyenziwe ezinye izinto, usebenzisa imikhiqizo ekhethekile nge metal threaded ifaka okushunyekiwe noma ne nati cap.

Abakhi polypropylene kwagcizelela amapayipi

Akusiyo imfihlo ukuthi uma uthenga amashubhu of okumqoka kuba kukhethwa kahle kungase kutholakale umkhiqizi ezimakethe zomhlaba Russian futhi. Namuhla sethula ezinye brand ethandwa ukuthi ngokukhethekile ukukhiqizwa ezinjalo.

FV Plast (Czech Republic)

Le nkampani ezikhethekile womshini polypropylene amapayipi Ukushisa, ashisayo nabandayo amanzi, bafudumale. imikhiqizo yenkampani itholakala kuphela ezimpunga aluminium ne-fiberglass ungqimba.

"Metak" (Russia)

Le nkampani inyathelisa ezihlukahlukene imikhiqizo ephuma polypropylene, kuhlanganise amapayipi ingilazi fibre kwagcizelela ngaphansi kwegama lomkhiqizo "Metak Fibre». imikhiqizo yenkampani mahle izinhlelo egcwele phama Ukushisa.

Banninger (Germany)

Inkampani German ukhiqiza imikhiqizo emihle kakhulu kukhona of eliphezulu kakhulu futhi waba nokwethenjelwa ukusebenza. Umthengi uyithole ngokushesha amafasitela esitolo Emerald oluhlaza.

Ekuphetheni, Ngithanda ukuncoma kubafundi bethu hhayi ukuthenga polypropylene kwagcizelela izinkampani engaziwa ukuthi musa ngisho igama yabo brand kwilebula. Igcina esincane uma uthenga, ungalahlekelwa imali eningana (imizwa, isikhathi) lapho eliphansi imikhiqizo wehluleka. Futhi lokhu kwenzeka ngokuvamile okwamanje esibi.
