Polypropylene kanjani ngokoqobo? Nokufaka futhi amapayipi kwe-polypropylene

Polypropylene buthola kwayo ezimweni yesimanje. It has zonke izidingo izinga efanele, kulula ukufaka futhi izindleko iphansana.

Ngakho-ke, abaningi amanzi ompompi kanye Ukushisa eqoqwe lapho usebenzisa le nto. Polypropylene nokufakwa ezixhunywe esebenzisa brazing ukwakha isakhiwo Monolithic. Kusenjalo emalungeni we lonke ipayipi.

Nokho, nokufakwa eyenziwe polypropylene kumele ngendlela efanele ukukhetha bafudumale, ukukhucululwa, namanzi.

Umqondo jikelele nokufakwa

Noma yiluphi uhlelo lapho amanzi ithuthwe, yakhiwa amashubhu nebudlelwano bawo. Lokhu nokufakwa. Polypropylene kulokhu ubhekwa esihle.

NgesiNgisi igama elithi "kufaneleka" lisho ukuthi "ukukhweza", "ukuxhuma". Zisetshenziswa phinda amaphayiphi iqonde, izinkomba, amagatsha. Ngosizo lwabo, ushintsho komunye ipayipi ubukhulu kwenye.

Nokufaka futhi amapayipi nokulethwa elinama ezifana polypropylene, kungenziwa ashiselwe. Lokhu kwenzeka ngokushesha kakhulu uma usebenzisa yensimbi nokunamathisela ngomthofu ne Imibhobho esemzimbeni. Kulokhu emalungeni ngeke kwenzeke nge awokuthi.

Le mpahla ingenye izinzuzo ezibaluleke kakhulu. Namuhla, Isidingo salokhu nokufakwa. Polypropylene isetshenziswa yonke indawo.

Ubukhulu

Abakhiqizi ukukhiqiza ezihlukahlukene osayizi efanelekayo. Lokhu kwenza kube lula ukukhetha zinhlobo oyifunayo. Kukhona ukuxhumana ngokubhanqwa wentambo ngaphandle kwalo. Basuke akhethwa ngokusekelwe izimo zokusebenza.

Uma lokhu kufaneleka ngentambo, kungaba yokuhlukanisa futhi lonke. Lokhu kufanele kubhekwe lapho ukhetha usayizi olungile.

Polypropylene kuyiphi nokufakwa avame ukusetshenziswa lapho kwenziwa izinhlelo ezahlukene, ivumela inqwaba izakhi ezahlukene.

Amasayizi ngokuvamile ezisetshenziswa ezibhekwa izingxenye nge cross-section 20, 25, 32, 40 mm. Ukuze ilungiselelo kohlelo namanzi asetshenziswa multi-storey izakhiwo, ngisho usayizi ezifana 110mm.

ubukhulu ukubala senziwa ikhumbula ubude ohlelweni lonke. I emikhulu kunjalo, abantu abaningi ipayipi kanye nokufakwa kwayo ukuze ifakwe.

okunezinhlobonhlobo

Ukwabela izakhi ezahlukene ohlelweni. Ingabe bonke ukucupha okungenzeka nokufakwa (polypropylene).

Amanzi, umoya omncane, ukushisa noma amanzi ukuzisebenzisa ngokugcwele. Inqawe kwale nto akusho bend, ngakho ukusebenzisa ngeke compounds kunoma isiphi isimo. kukhona:

• bamba;
• ukuhwebelana;
• kukufanele wena;
• yokuwela;
• Imigudu;
• emakhoneni.

I elihlangana kuzovumela ukuxhuma amapayipi we ubukhulu efanayo, futhi ushintsho - ehlukile cross-section. Inyunyana liyadingeka uma isidingo ukuxhuma zokuxhumana nge hose nezimo. Yokuwela zingezokunikeza amagatsha. Plug uphawu ivumela kwangqingetshe ipayipi.

Ngakho, ukujikeleza engenziwa usebenzisa ekhoneni. Ngokuvamile, zingabantu 45 no-90 degrees.

wokugubha

Ukuze kungabi nesikhathi esifushane ukwenza indawo amapayipi kufanele ukhethe kubo. Ukuze wenze lokhu kufanele sinake mshini.

Polypropylene amapayipi kanye nokufakwa for amanzi ayifanele bafudumale. Ukumakwa lisetshenziswa yonke imininingwane.

PN10 kungokwalabo izingxenye mncane-udonga ngoba amakhaza amanzi itheku ukuze +20 degrees. Operating ingcindezi - 1 MPA.

PN16 eyenzelwe ngamanzi abandayo ne umfutho ophakeme.

PN20 kubonisa ukuthi into zingamelana ishisisa ukuba +80 degrees kanye nokucindezela - up 2 MPA.

Ukuze amanzi ashisayo ukunikezela Ukushisa izakhi usetshenziswe ngendlela PN25 wokugubha. Bayakwazi ukugcina ukushisa kuze kube degrees 95. Kulesi simiso ovumelekile ingcindezi lingafika ku 2.5 MPA.

Uma amapayipi ufake ephakeme lokushisa liquid amanzi abandayo, baqala deform. Ngakho-ke, yize ukubaluleka amakilasi ahlukene pipe ihlukile kakhulu, kufanele uthenge kuphela nemingcele ezifanele kohlelo nogwali nokufakwa.

isithunzi

polypropylene nokufakwa Ukushisa, amanzi kunezinzuzo eziningana.

1. Isisindo ongaphakeme kwenza kube lula ukusebenza.
2. ukuphila isikhathi eside. Ukushisa polypropylene ihlala engaba ngu-25, futhi emakhazeni amanzi nezokuxhumana - engu-50.
3. izindleko iphansana.
4. ukufakwa okusheshayo.
5. ukubukeka Tebuciko.

Zonke lezi zimfanelo zibenza akuleso edingeka kangaka. ngenxa yokuthandwa kwayo, liyakhula cishe nsuku zonke. Nokufaka amelana ukugqwala futhi ukuhlasela zamakhemikhali. Abenzi lutho imali limescale, ama-bacterium musa wande.

amaphutha

Polypropylene nokufakwa ngokulungisa amapayipi amanzi kanye nezinye izinhlelo benezingane eziningi izimfanelo ezimbi. rigidity enkulu abaziphatha ngayo. Akumelwe zintengezele. Ngakho-ke, ukufakwa kuzodinga ngempela inani elikhulu ukuxhumana.

I yokuntula futhi zihlanganisa isidingo imishini ekhethekile. It kuyodingeka ukuthenga okwakungaqhutshelwa kuyo umhlangano.

Polypropylene kubuye kakhulu sensitive ukwanda lokushisa. Ngenxa yalokhu, kungase ukunwetshwa ububanzi luqhubeke yemigqa. Ngenxa yalesi okokusebenza lokushisa ezibalulekile.

Nokho, lezi yokuntula ukuphaphatheka phambi zonke izimfanelo. kudivayisi nokunamathisela ngomthofu akuyona eqolo uma udinga solder ipayipi ekhaya. Professionals ngokushesha recoup izindleko izimpahla ezibizayo ukusetshenziswa njalo.

obandayo

Polypropylene, kusukela lapho nokufakwa asetshenziswa ukuvuselelwa izinhlelo ezahlukene, kuhilela ukusetshenziswa ikakhulukazi inhlangano ubuchwepheshe.

Ukuze wenze lokhu kuyodingeka ukuthenga yensimbi ekhethekile nokunamathisela ngomthofu ne Imibhobho esemzimbeni edingekayo ubukhulu. Kuyadingeka ukuba usike ipayipi sikelo ekhethekile. Futhi, i-kuphekwe Milling umsiki, telunyawo, umaka.

Ukuthwala inhlangano electrosolderers setha lokushisa 240-260 degrees. Nge Planer asuswe ipayipi ungqimba maphakathi ucwecwe-2 mm.

Ngakolunye uhlangothi nokunamathisela ngomthofu umlomo wombhobho lufakwa igemfe ngakolunye - fitting. Ligcinwe Ukushisa isikhathi 3-5 isekhondi. Basuke isuswe kanyekanye ukukhiqiza ipayipi kwakwakhe nge efanelekayo. Nikeza izakhi kudambe bese uhlole ngokuhlanganyela. Lena esheshayo lula ukufaka, ezingabizi, ngisho Wabasaqalayo.

Ngemva kokubukeza lokho kwaziswa njengeseluleko polypropylene nokufakwa manje kakhulu ziphoqa, ungakwazi self-babuthane izinhlobo ezahlukene izinhlelo. Kahle eqoqa yonke izinto ukuze afeze ukuba umhlangano wabo ngendlela efanele, ningaqiniseka ukuthi ukusebenza yesikhathi eside kohlelo. Njengoba yezinto ezisetshenziswa kakhulu, polypropylene ke unezimfanelo eziningi ezinhle. Ubulula yokumiswa, ukuqina kanye ongaphakeme izindleko ukwanda ukufunwa nokufakwa kuwo.
