Emgqeni wokukhiqiza amapayipi epulasitiki, ubuchwepheshe obungenamakhono bomqhubi kanye nokusebenza komshini kuzobangela ukuthi ipayipi lepulasitiki libonakale lilukhuni endaweni yangaphandle, indandatho ye-jitter ngaphakathi, ukushuba kodonga olungalingani, ukujikeleza okwanele nokunye. Ngakho-ke, ukulungiswa okufika ngesikhathi kwenqubo yokukhiqiza amapayipi epulasitiki kanye nokuxazulula izinkinga zomugqa wokukhiqiza ipayipi lepulasitiki kungathuthukisa ikhwalithi yomkhiqizo.

1.Indawo yangaphandle yepayipi lepulasitiki ilukhuni
● Lungisa izinga lokushisa lenqubo;
● Yehlisa izinga lokushisa lamanzi okupholisa, izinga lokushisa elingcono kakhulu lamanzi okupholisa lamapayipi e-PE ngu-20～25℃;
● Hlola umzila wamanzi ukuze ubone ukuthi akukho yini ukuvaleka noma umfutho wamanzi onganele;
● Hlola ukuthi indandatho yokushisisa yomgqomo, ikhanda, njll. yonakele yini;
● Lungisa ukugeleza kwamanzi angenisayo komkhono wokulinganisa;
● Hlola izakhiwo nezinombolo zeqoqo zezinto ezingavuthiwe;
● Hlola izinga lokushisa lomnyombo wesikhunta. Uma iphakeme kunezinga lokushisa lesigaba sokufa, yehlisa izinga lokushisa lenhliziyo;
● Hlanza inhlanganisela yesikhunta;

2. Ama-grooves avela ngaphandle kwepayipi lepulasitiki
● Lungisa ukucindezela komthombo wamanzi womkhono wokulinganisa, futhi ukuphuma kwamanzi kuyadingeka ukuze kulinganiswe;
● Lungisa i-engeli yombhobho ebhokisini lokubumba ivacuum ukuze wenze ipayipi liphole ngokulinganayo;
● Hlola idayi, ukulinganisa umkhono, umshini wokusika, nezinye izingxenye zensimbi ukuze uthole imfucumfucu, ama-burrs, njll.;

3. Ama-grooves avela endaweni engaphakathi
● Hlola ukuthi amanzi ayangena yini eshubhuni elingaphakathi. Uma kungena amanzi, cindezela umbungu weshubhu wesikhunta ngemva nje kokuphuma ukuze uvale umgodi ongaphakathi;
● Yehlisa izinga lokushisa langaphakathi lesikhunta;
● Hlanza bese upholisha isikhunta;

4. Kuvela iringi yejita ngaphakathi kwepayipi
● Lungisa ukuphuma kwamanzi komkhono wokulinganisa ukuze ulenze lilingane;
● Lungisa i-vacuum degree yegumbi lesibili ukuze i-vacuum degree yekamelo elingemuva iphakame kancane kune-vacuum degree yekamelo elingaphambili;
● Hlola ukuthi isivalo sevacuum siqinile yini;
● Bheka ukuthi ugandaganda uyazamazama yini;
● Hlola ukuthi umshini omkhulu ukhipha ngokulinganayo yini;

5. Akukho vacuum
● Hlola ukuthi i-inlet yamanzi yepompo yevacuum ivaliwe yini. Uma ivinjiwe, yivule;
● Hlola ukuthi ingabe iphampu yevacuum ivame ukusebenza;
● Hlola ukuthi ipayipi levacuum liyavuza yini;
● Hlola ukuthi imbobo encane emaphakathi nesikulufu sokucindezela isikhunta esiyinhloko ivinjiwe yini. Uma ivinjiwe, sebenzisa ucingo oluncane lwensimbi ukuze uyisuse;

6. I-diameter yangaphandle yepayipi iphelelwe ukubekezelelana
● Ubukhulu bendilinga yangaphandle bungashintsha ngokulungisa idigri ye-vacuum;
● Ubukhulu beringi yangaphandle bungashintsha ngokushintsha isivinini sokudonsa;
● Lungisa usayizi wembobo yangaphakathi yomkhono wokulinganisa;

7. Ukuyindilinga kwepayipi akubekezelelani
● Lungisa i-engeli ye-nozzle emshinini wokusetha i-vacuum kanye nebhokisi lokufafaza ukuze upholise ipayipi ngendlela efanayo;
● Hlola umshini wokwenza ivacuum, izinga lamanzi ebhokisini lesifutho, kanye nokucindezela kwegeji yokucindezela kwamanzi ukuze wenze umthamo wesifutho ube mkhulu futhi ube namandla;
● Hlola izinga lokushisa lamanzi lomshini wokusetha i-vacuum kanye nebhokisi lokufafaza. Uma ingaphezulu kuka-35℃, isistimu yamanzi abandayo noma ibhokisi lokupholisa lesifutho kufanele lengeze;
● Hlola umzila wamanzi futhi uhlanze isihlungi;
● Lungisa inqubo;
● Hlola futhi ulungise ukujikeleza kwembobo yangaphakathi yomkhono wokulinganisa;
● Lungisa umhlahlandlela wepayipi kanye nedivaysi yokubopha ukuze ubuyekeze i-ovality yepayipi;

8. Ubukhulu bodonga lwamapayipi angalingani
● Lungisa ukujiya kodonga esikhunjeni;
● Lungisa i-engeli ye-nozzle emshinini wokusetha i-vacuum kanye nebhokisi lokufafaza ukuze wenze ipayipi liphole ngokulinganayo; lungisa ukuphuma kwamanzi komkhono wokulinganisa ukuze ulingane;
● Hlukanisa isikhunta, hlola ukuthi izikulufu ezingaphakathi kwesikhunta azikhululekile yini, bese usiqinisa kabusha;

9. Izinga lokushisa leplastiki liphezulu kakhulu
● Lungisa inqubo;
● Lungisa izinga lokushisa lokushisa kwe-mold core futhi ukhiphe umoya futhi upholise isikhunta;
● Ukushisa okukhulu kwesikulufu kuphezulu kakhulu, buyisela isikulufu;

10. Ubude bokusika obungalungile
● Hlola ukuthi isondo elide licindezelwe ngokuqinile yini;
● Hlola ukuthi isondo elide liyashwibeka yini, bese uqinisa amabhawodi okulungisa amasondo amade;
● Hlola ukuthi i-stroke switch yomshini wokusika yonakele yini;
● Hlola ukuthi isishumeki esijikelezayo sonakele yini;
● Ukuthi izintambo zesishumeki esijikelezayo zinqanyuliwe yini (ukuthi isihlalo sepulaki yendiza sixhumene kahle yini);

Indawo ngayinye ebiyelwe ezimele yodwa (itheminali ye-PE) kufanele isekelwe ngokuhlukene endaweni ephelele ukuze kusekelwe okuthembekile. Iphuzu eliphansi kufanele libe nesigxobo sokumisa esihlangabezana nezidingo zesisekelo sikagesi. Akuvunyelwe ukuxhuma izivalo ezizimele zodwa (amatheminali e-PE) ochungechungeni naphansi. Uma kungenjalo, bazokwethula i-Interference pulse, okubangela ubude bokusika obungalungile;

11. Inkinga yelebula ye-Co-extrusion
Ukusatshalaliswa kwemichilo yokuhlonza i-co-extrusion: Ngokuvamile, kubangela ukukhethwa okungafanele kwezinto zabasebenzisi zokukhishwa ngokubambisana. Izinto ezihlukile, njenge-PE, kufanele zisetshenziswe. Uma kunesidingo, izinga lokushisa lesigaba se-extrusion linganciphisa;
I-co-extruder ayikwazi ukukhama: misa i-extruder eyinhloko, vula umshini we-co-extrusion kuqala, futhi uvule idivayisi ye-co-extrusion cishe imizuzu eyi-10 ngaphambi kokuvula umsingathi;
Umugqa womaka we-co-extrusion mncane kakhulu noma ubanzi kakhulu: Ngokuvamile, ubangela ngokungafani phakathi kwevolumu yokukhishwa komshini we-co-extrusion kanye nesivinini sokudonsa sepayipi futhi kufanele kulungiswe, imvamisa yesiguquli sefrikhwensi yenjini ye-co-extrusion noma ukushintsha isivinini sokudonsa ukuze sifane nalawa mazinga amabili;
Okwesibili isizathu sokuthi kungani ijaji lamanzi okupholisa lesigaba sokuthulula se-co-extruder lingadluli emanzini okupholisa;
Enkambweni yangempela yokukhiqiza yomugqa wokukhiqiza ipayipi, kuzoba nezinye izimo ezingavamile, okufanele zibhekane nazo ngokuvumelana nesimo esiqondile.
