Ukushisa simiso polypropylene amapayipi: ngebuhle izici ukufakwa

Kuze kube manje, ezinkulu-ukusabalala uhlelo Ukushisa polypropylene amapayipi. Lokhu kungenxa yokuthi imikhiqizo yesimanje amapayipi benezingane eziningi amathuba kanye nezinzuzo ukuthi azange abe ababengaphambi zabo (PVC amapayipi kanye nokufakwa kwayo kwenziwa kusukela polyethylene).

izinzuzo

imikhiqizo Industrial eyenziwe polypropylene okuhlala isikhathi eside kakhulu. Uma kahle ukukhetha uhlobo afunekayo, ingahlala iminyaka engu-50 noma ngaphezulu. Polypropylene amashubhu, ngenxa ukwakheka kanye yokukhiqiza amasu esiyingqayizivele, asidingi ezengeziwe ukwahlukanisa staining futhi musa ukuqoqa phezu ukufingqa.

Heat ukonga lapho usebenzisa le mikhiqizo 20%. Amashubhu musa nokugqwala, abumane ngaphakathi imali calcareous futhi qwembe Ukwedlula ngokuphelele bushelelezi izindonga zangaphakathi, okwenza kungabi ukuxabana futhi ukumelana, ngaleyo ndlela amanzi ugeleza ngokukhululekile ngokusebenzisa ipayipi. Ababona wokuba umbhidisi ugesi. Ngaphandle Ukushisa kusuka polypropylene amashubhu uyakwazi withstanding izinga lokushisa irekhodi uphawu 95 ° C.

Imikhiqizo kulula ukuthutha futhi wokumiswa, njengoba ewonke alula kakhulu kunensimbi. usike Kalula nge sikelo ekhethekile. Ukufakwa kwe-polypropylene amapayipi kohlelo bafudumale kuthatha isikhathi esincane. Ukuze uxhumano phakathi ipayipi kanye nokufakwa kudinga nokunamathisela ngomthofu ithuluzi ekhethekile. Kulokhu, kube semikhawulweni umkhiqizo ngaphandle kwesidingo yokuhlanza. Ngenxa Ukushisa eqinile ekhuthaza kwe-polypropylene amapayipi kubhekwa okuthembekile.

obandayo

Lapho obandayo umkhiqizo, awuvezi Ukuhlanekezelwa yabo noma eguqa njengoba polypropylene - sisetshenziselwa izinto kanzima, okusho ukuthi zonke ematfuba kanye nezinye izenzo kumele kwenziwe esebenzisa polypropylene nokufakwa. umsebenzi Ukufakwa is kungcono ishiyelwe ochwepheshe, kungenjalo kukhona ingozi yokuthola igciwane eliphansi bafudumale system. Uma kunesidingo, ipayipi polypropylene kungaba kancane bent, amalahle indawo oyifunayo usebenzisa isakhiwo dryer. Nokho, uma nengcindezi enamandla ku umkhiqizo impahla nolimi bangase babe ukusonteka baphule okufanayo.

Okwamanje kukhiqizwa tube ubude 4 amamitha. imikhiqizo ekhiqizwa ka ezintathu izinhlobo, ngalinye elikwazi yakhelwe ohlelweni oluthile (PN10, PN20, PN25). Uhlelo Ukushisa aboshelwe polypropylene amashubhu, ngokuvamile ezenziwe PN25. Okunye lolu hlobo ungachazwa ukuthi sigcizelelwa kusuka ngaphakathi nge aluminium ucwecwe, Ngakho-ke, hhayi plastic. Ngenxa tube yokugcizelela iqoqo lesithathu lingasetshenziswa ngesikhathi ukucindezela-8 izikhathi eziphindwe kanye okushisa afinyelela ku-70 ° C, lapho isikhathi - engu-50. Kodwa uma amanzi ingcindezi kanye lokushisa izici kuzokhulisa ukuphila tube kuzoncishiswa.

isiphetho

ungakwazi ukuthenga polypropylene amapayipi Ukushisa ngo yisiphi isitolo hardware. Intengo iphansana, okubenza babe atholakalayo. Izindleko incike ubukhulu (25 ukuze 125 mm) kanye zokhahlamba kusuka mayelana 40 1500 noma ngaphezulu ngamunye imitha ruble sikwele. Iningi kakade kubonakala izinga okusezingeni eliphezulu we impahla kanye amanani yeningi.
