Ukufakwa Kwepayipi Lepulasitiki Amathiphu Okuxhumana Kwezobuchwepheshe

I-extrusion yamapayipi idinga ukuba ne-viscosity ephezulu, kuyilapho ukubunjwa komjovo kudinga impahla ene-liquidity ephezulu. Izidingo zokusebenza komkhiqizo zokuhlanganisa amapayipi ziphezulu kakhulu.

Kumapayipi kanye nezimpawu ezihlangene embonini esebenzisa ubuchwepheshe obuthuthukisiwe, ngokusebenzisa i-catalyst esebenzayo inoveli iyadingeka ukulawula isakhiwo samangqamuzana.

Inqubo yokwenza ukukhiqizwa kwamapayipi iyinkimbinkimbi kakhulu, ngisho nokubumba okukhulu okujikelezayo kwamalunga amakhulu. Ukusetshenziswa kwaseYurophu kwamathani epulasitiki angaba yizigidi ezi-3.5 ngonyaka. Njengoba ipayipi elisendle, ukuhlinzekwa kwamanzi, amapayipi amanzi, imigwaqo kanye ne-drainage applications ezindaweni ezifana nokukhuphuka, imakethe iyakhula.

I-polyethylene ehlanganisiwe isetshenziswa kakhulu emakethe yamapayipi, igwema ukulahlekelwa kwamapayipi ethusi abizayo. Ingafakwa ngenani eliphansi futhi ngokushesha. Ukufakwa kwe-PEX okusetshenzisiwe kunganciphisa isistimu, futhi kukuvumela ukuthi usebenzise ukufakwa kwamapayipi okuhlukahlukene. Amandla ayisici esibaluleke kakhulu, amandla angama-66% asetshenziswa kule nqubo, futhi lawa asetshenziswa kakhulu kumamotho kagesi nasekushisiseni imiphongolo. Sebenzisa kuphela isilawuli sejubane lemoto, unganciphisa umsebenzi ongadingekile; izinga lokushisa emgqonyeni elawulwa 30-70% Ukushisa izindleko zingagcinwa. Ama-polymers ane-fluorinated amapayipi ezimboni kanye namapayipi okucindezela, lawa ma-fluoropolymer ezinhlelweni zamanzi ashisayo nokufakwa ekumelaneni kwamakhemikhali okuhle kakhulu.

Ubuchwepheshe bokufakwa kwamapayipi epulasitiki, futhi futhi kudingeka baqhubeke nokusungula, ukuhlanganisa nokuthuthukiswa kwezikhathi, baqonde izidingo zokuthuthukiswa kwazo zonke izihwebo.
