Ipayipi likathayela elinezindonga ezimbili

Incazelo emfushane:

Ipayipi likathayela elinezindonga ezikabili: iwuhlobo olusha lwepayipi elinodonga lwangaphandle lwe-annular nodonga lwangaphakathi olubushelelezi. Isetshenziselwa ikakhulukazi ukulethwa kwamanzi amakhulu, ukuhlinzekwa kwamanzi, ukuthuthwa kwendle, ukuthuthwa kwendle, i-exhaust, umoya wesitimela ohamba ngaphansi komhlaba, umoya wezimayini, ukuchelela emapulazini nokunye ngengcindezi yokusebenza engaphansi kuka-0.6MPa. Umbala wangaphakathi wodonga lwezinsimbi eziphindwe kabili ngokuvamile uba luhlaza okwesibhakabhaka nomnyama, kanti ezinye izinhlobo zizosebenzisa ophuzi.

Ipayipi likathayela elinezindonga ezimbili
Yenziwe "nge-HDPE (high-density polyethylene) ipayipi likathayela", "PVC-U (i-polyvinyl chloride eqinile) ipayipi likathayela", "PP (polypropylene) ipayipi likathayela", njll. njengezinto zokusetshenziswa eziyinhloko. , I-extruder co-extrudes yangaphandle, ukubunjwa kwesikhathi esisodwa, udonga lwangaphakathi lubushelelezi, udonga lwangaphandle luboshiwe, futhi kukhona ungqimba olungenalutho lwepayipi yepulasitiki phakathi kwezindonga zangaphakathi nezingaphandle.

Izici zamapayipi epulasitiki kathayela :
1. Isakhiwo esiyingqayizivele, amandla aphezulu, ukucindezelwa kanye nokumelana nomthelela.
2. ukuxhumana kulula, okuhlangene kuvalwe kahle, futhi akukho ukuvuza.
3. isisindo esincane, ukwakhiwa okusheshayo kanye nezindleko eziphansi.
4. Impilo yenkonzo yokungcwatshwa ingaphezu kweminyaka engama-50.
5. I-Polyethylene iyi-polymer ye-hydrocarbon enama-molecule angewona ama-polar futhi imelana nokugqwala kwe-asidi ne-alkali.
6. Izinto zokusetshenziswa ziyizinto eziluhlaza zokuvikela imvelo, ezingenabuthi, ezingagqwali, azilinganisi, futhi zingagaywa kabusha futhi zisetshenziswe.
7. Ububanzi bokushisa bokusetshenziswa bubanzi, ipayipi ngeke liphuke endaweni engu--60 ℃, futhi izinga lokushisa lendawo yokudlulisa ngu-60 ℃.
8. Izindleko eziphelele zephrojekthi ngokuyisisekelo ziyafana nalezo zikakhonkolo, futhi izindleko zokusebenza ziphansi.
9. Asikho isisekelo esidingekayo uma izinga lomhlabathi lilihle.

Isicelo:
Amapayipi kathayela epulasitiki asetshenziswa kabanzi ezindaweni eziningi njengangezansi
1. Amapayipi okukhipha amanzi kanye nokukhipha umoya ezimayini nezakhiwo;
2. Ubunjiniyela bakamasipala, amapayipi amanzi angaphansi komhlaba kanye namapayipi endle ezindaweni zokuhlala;
3. Ukuchelela kanye nokukhipha amanzi endaweni yokonga amanzi epulazini; amapayipi okukhipha indle ezindaweni zokukhuculula indle nezindawo zokulahla udoti;
4. Amapayipi okungenisa umoya ngamakhemikhali kanye namapayipi ahambisa amakhemikhali nezimayini;
5. Ukusetshenzwa sekukonke kwemithombo yokuhlola amapayipi; amakhilomitha anesivinini esikhulu samapayipi angcwatshwe ngaphambili;
6. izintambo zamandla kagesi aphezulu, imikhono yokuvikela ikhebula leposi nelezokuxhumana, njll.
