Enqubweni yokushisela okushisayo kwepayipi le-PE, kuyadingeka ukulawula ngokuphelele ikhwalithi yayo, ukwenza umsebenzi wokuphatha opharetha, imishini yomshini, izinto zokushisela kanye nenqubo yokushisela, ukuthembela emsebenzini wokuhlola, futhi ulwele ukunciphisa imifantu yokushisela kanye imifantu.Njengamanje, amabhizinisi okwakha aseShayina abekwi-hot melt welding

Qala ukusebenzisa ubuchwepheshe bokuhlola be-ultrasonic ukuze wenze umsebenzi wokuhlola ofanele, ongathola ngesikhathi esifanele izinkinga zekhwalithi yokushisela ngaphakathi kwamapayipi e-PE, uthathe izinyathelo eziphumelelayo zokulawula ikhwalithi ngaphambi nangesikhathi sokushisela, futhi ulawule ikhwalithi yokwakha ngokuhlola ngemva kokushisela.

1) Izinyathelo zokulawula ikhwalithi ngaphambi kokushisela.

Ngaphambi kwe-welding, kuyadingeka ukwenza umsebenzi omuhle ekulawuleni izinga, okungathuthukisa izinga lomsebenzi.Okokuqala, kubaqhubi be-welding, ikhwalithi yabo yobuchwepheshe kanye namakhono adinga ukulawulwa ngokuqinile, futhi kudingeka babe nezitifiketi zeziqu zokushisela.Ngasikhathi sinye, kuyadingeka ukwakha isikimu esihlela sokuphathwa kwekhwalithi futhi kwakhiwe ibhizinisi lekhwalithi ephezulu ngokuya ngezidingo zalo zangempela zentuthuko.

Ithimba lethalente lekhwalithi, ukuze lithuthukise ikhwalithi yokwakha.Mayelana nezinto zokusetshenziswa zokushisela, izidingo zekhwalithi zikazwelonke ezifanele zizohlangatshezwana nazo.Okwesibili, ekukhetheni umshini wokushisela, kuyadingeka ukusebenzisa ngokugcwele umshini wokushisela kagesi ozenzakalelayo ukuze ube nemisebenzi yesinxephezelo esizenzakalelayo, ukushisisa okuzenzakalelayo nokucindezela, ukubonisa okuzenzakalelayo kolwazi lwedatha yokushisela, ukuzihlola okuzenzakalelayo kanye nokuzi- ukuqapha

Ukutholwa okuzenzakalelayo, i-alamu ezenzakalelayo neminye imisebenzi yokusekela ukuthuthukiswa komsebenzi wokushisela.Okwesithathu, kuyadingeka ukukhetha ngokwesayensi inqubo yokushisela futhi uyihlole.Ngesikhathi esifanayo, kuyadingeka ukuqinisekisa ukuthi izinga lokuncibilika lihlangabezana nemithethonqubo efanele futhi azikho izinkinga zekhwalithi ezivunyelwe.Okokugcina, kumapharamitha wenqubo yokushisela, kuyadingeka ukwenza umsebenzi omuhle wokuhlola nokulawula imingcele yawo yokushisa.

Izinga lokushisa lokulungiselela lingaphakathi kuka-230 ℃, ukuze lithuthukise izinga layo lokusebenza.Ngesikhathi esifanayo, ikhwalithi yamapayipi nokufakwa kufanele kuhlolwe ngokucophelela.Ngemuva kokuthi ikhwalithi ihlangabezane nezidingo ezifanele, isikhombimsebenzisi se-welding sizolungiswa, ukwelashwa kokuhlanza kuzokwenziwa, futhi ungqimba lwe-oxide luzosulwa.

2) Izinyathelo zokulawula izinga ngesikhathi sokushisela.

Emsebenzini we-welding wangempela, kuyadingeka ukwenza umsebenzi omuhle ekuphathweni kwekhwalithi, ukunciphisa ukuhlukumeza futhi kancane kancane ukwandise uhlelo lwayo lokusebenza.Okokuqala, izinga lokushisa lomshini wokushisela lidinga ukulawulwa cishe ku-210 ℃ ukuze kube lula ukushisela.Ngaphezu kwalokho, esimweni sezulu esinomoya noma semvula neqhwa, akusizi ukwenza umsebenzi wokushisela futhi ugweme izinga lokushisa elidlulele.

Isimo esiphansi.Okwesibili, ochwepheshe bezokwakha badinga ukusebenza ngokuhambisana ngokuqinile nemithethonqubo efanele ukuze baqinisekise ukunemba kolwazi lwedatha yomsebenzi.Okwesithathu, imvume yokwakha impahla kufanele ilawulwe ngaphezu kuka-21mm, futhi isivinini sokusebenza nezinga lokushisa kufanele kulawulwe ngokwesayensi ukuze kugwenywe izinkinga zokushisela.Okwesine, ijoyinti yokushisela idinga ukupholiswa ngaphansi kwengcindezi ezinzile (ukupholisa komoya wemvelo).Ayikwazi ukunyakaza noma ingcindezi eyengeziwe.Okwesihlanu, ngesikhathi se-welding, kuyadingeka ukuqinisekisa ukuthi ubuso bepuleti lokushisa buhlala buhlanzekile.

3) Izinyathelo zokulawula ikhwalithi ngemuva kokushisela.

Ngemuva kokuqeda umsebenzi wokushisela, inkampani yokwakha idinga ukuhlola konke ukubukeka kwezingxenye zokushisela, futhi isebenzise indlela yokuhlola ukusika (ukuhlolwa kwesampula ye-notch kufika ku-5%) ukuthola izinkinga ezikhona emsebenzini wokushisela ngesikhathi. .Ngesikhathi esifanayo, ochwepheshe badinga ukwenza ukuhlolwa kwengcindezi futhi bahlanganise ukuhlola okungahleliwe nokuhlola okuphelele, njengomthamo we-tensile.

Esilinganisweni nasekuhloleni okungahleliwe, uma izinkinga zekhwalithi sezitholakele, ukuhlolwa okuphelele kuzosetshenziswa ukuze kutholwe ukuthi zikhona yini izinkinga kuzo zonke izingxenye zokushisela.
