Eminyakeni emibili edlule, ukukhiqizwa kwamapayipi ensimbi ane-plastic lined ezweni lami kuye kwathuthuka ngokushesha, ikakhulukazi emkhakheni wokuhlinzekwa kwamanzi.Njengamanje, ngaphezu kuka-90% wamapayipi okuhambisa amanzi ezakhiwo eziphakeme e-Shanghai asebenzisa amapayipi ensimbi anepulasitiki.
Ipayipi lensimbi elinepulasitiki aligcini nje ngokuba namandla aphezulu, ukuqina, ukumelana nomlilo, nokumelana nezinga lokushisa kwamapayipi ensimbi kodwa futhi linokuvikelwa kwenhlanzeko nemvelo nokusebenza okungalingani kwamapayipi epulasitiki.Amapayipi ahlanganisiwe.
Ipayipi lensimbi elinomugqa wepulasitiki likhipha ipayipi lepulasitiki bese limbozwa ngongqimba olunamathelayo, bese lifakwa epayipini lensimbi, liwushise, licindezele, lipholile, futhi libunjwe kanye nepayipi lensimbi, bese lihlanganisa ipayipi lepulasitiki nepayipi lensimbi. ngokuqinile ndawonye, engasetshenziselwa ukuthuthwa kwamanzi abandayo noma ukulethwa kwamanzi ashisayo.
I-1.Imishini yepulasitiki ehlanganisiwe kanye nokugeleza kwenqubo
(1) Imishini yokubumba yamapayipi epulasitiki
Amapayipi epulasitiki akhiqizwa ama-screw extruder, okuhlanganisa ama-extruder ashisayo, ama-crawler tractor, ukupholisa i-vacuum, amathangi okubumba, imishini yokusika-ubude, amasistimu okulawula ugesi kanye nezinga lokushisa, njll.
(2) Impahla yepulasitiki yolwelwesi
①Ithebula lokuphakelayo lisetshenziselwa ukubeka amapayipi ensimbi nokufaka amapayipi epulasitiki kumapayipi ensimbi;
②Isistimu yokudlulisa iketango ishayela ipayipi lensimbi esiteshini ngasinye;
③Isithando sokushisa sihlukaniswe izingxenye ezinhlanu ukuze kushise ipayipi lensimbi, ukuze izinga lokushisa lengxenye ephakathi yepayipi lensimbi liphakeme kunalelo lezinhlangothi ezimbili, futhi lehla nge-gradient ukuqinisekisa ukuthi igesi egebe phakathi ipayipi lepulasitiki kanye nepayipi lensimbi lingageleza lisuka endaweni ephakathi liye epayipini lensimbi ngesikhathi senqubo yokucindezela.Ukukhipha emikhawulweni yomibili;
④Isistimu yokulawula ugesi ilawula ngokuzenzakalelayo isenzo ngasinye salo lonke isethi yezisetshenziswa, futhi ilawula izinga lokushisa ngokuya ngokulungiselelwa kwepharamitha yenqubo;
⑤ Uhlelo lokucindezela lusebenzisa igesi ephezulu yokucindezela ukucindezela udonga lwangaphakathi lwepayipi lepulasitiki ukuze ipayipi lepulasitiki likhule futhi lixhumane ngokugcwele nodonga lwangaphakathi lwepayipi yensimbi;
⑥ Isistimu yokupholisa yesifutho ifutha futhi ipholise ipayipi lensimbi elicindezelweyo elinemigqa yepulasitiki ukuze ipayipi lepulasitiki libumbeke futhi lihlanganiswe ngokuqinile nepayipi lensimbi.
2. Umgomo wenqubo kanye nenqubo yepayipi yensimbi ene-plastic-lined
(1) Isimiso
Ngokushisisa ipayipi lensimbi elifakwe epayipini lepulasitiki, ukushisa kunikezwa i-thermoforming kanye nokubopha ipayipi lepulasitiki elinemigqa, bese ipayipi lepulasitiki licindezelwa ukwenza ipayipi lepulasitiki likhule futhi lihlangane nepayipi lensimbi ngokusebenzisa ungqimba wokunamathela.Ekugcineni, yakhiwa ngokupholisa nokubeka.
(2) Ukugeleza kwenqubo
Ukushiswa kwamapayipi ensimbi, ukuqhunyiswa kwesanti, ukufakwa kumapayipi epulasitiki anemigqa, amasethi esikhunta se-pressurization ephezulu, ukushisisa isithando somlilo nokugcinwa kokushisa, ukugcinwa kokushisa kokwandisa ingcindezi, ukukhishwa kwesithando somlilo, ukupholisa isifutho nokubunjwa, ukukhululeka kwengcindezi, amasethi esikhunta esicindezelayo, ukuphungula amapayipi Itheminali, ukuhlolwa. , ukupakisha, ukukala, ukugcina.
3. Izici zenqubo yepayipi yensimbi ene-plastic-lined
Ipayipi lepulasitiki kanye nesendlalelo sokunamathisela kukhiqizwa nge-co-extrusion, futhi isendlalelo se-adhesive se-hot-melt sihlanganiswa ebusweni bepayipi yepulasitiki.Lapho ipayipi lepulasitiki likhishwa, ubukhulu bongqimba lwe-adhesive ebusweni kufanele bufane.Ukufana kokuqina kwesendlalelo sokunamathisela kungahlulelwa ngokubheka umehluko ekukhanyeni kwezingqimba ezimbili zepulasitiki endaweni yokugcina yepayipi lepulasitiki.Amapayipi epulasitiki akhiqiziwe adingeka ukuthi abe nobuso obushelelezi futhi angabi ne-agglomeration ngaphakathi kodonga lwamapayipi.Ukuchezuka komkhawulo wokuqina kodonga esigabeni esifanayo akufanele kudlule i-14%, futhi ubukhulu bengqimba yokunamathisela kufanele ilawulwe phakathi kuka-0.2-0.28mm.
Ipayipi lensimbi elinomugqa wepulasitiki lihlanganisa ukusebenza okuhle kakhulu kwepayipi lensimbi nepayipi lepulasitiki, futhi izindleko ziphakeme kancane kunepayipi elifakwe emanzini ashisayo, okuyingxenye eyodwa kwezintathu kuphela yezindleko zepayipi lensimbi engagqwali.Inezinzuzo ezisobala ekusebenzeni kwezindleko phakathi kwamapayipi amaningi okuhambisa amanzi.Ngaphezu kwalokho, kulula futhi kunokwethenjelwa ukuyifaka futhi isiphenduke ipayipi elikhulu lokuhlinzeka ngamanzi amancane naphakathi.Ngenxa yokuthi ingasetshenziselwa ukuthuthwa kwamanzi ashisayo, inobubanzi besicelo esibanzi kunamapayipi ahlanganiswe ngepulasitiki ngaphansi kwezimo zamanje zobuchwepheshe.
