I-Polyethylene (PE) isetshenziswa kabanzi ku-Ukufakwa kanye nokufutheka kwamakhebuli wamandla kanye nezintambo zokuxhumana ngocingoNgenxa yamandla ayo amahle emishini, ukuqina, ukumelana nokushisa, ukufakwa, kanye nokuqina kwamakhemikhali. Kodwa-ke, ngenxa yezici ezihlelekile ze-Pe uqobo, ukumelana kwayo ekuqhekekeni kwengcindezi yemvelo kumpofu. Le ndaba ivelele ikakhulukazi lapho i-PE isetshenziswa njengezintambo zangaphandle zezintambo zezingxenye ezinkulu zengxenye.
1. Indlela yokuqhekeka kwe-PE Sheath
I-Sheath Sheath iqhekeka ikakhulukazi ezimweni ezimbili:
a. Ukuqhekeka kwengcindezi yemvelo Kubangelwa ikakhulukazi ukucindezelwa kwangaphakathi ngaphakathi komgodi nokuchayeka isikhathi eside ku-Polar Liquid. Ucwaningo olunzulu ngokuguqulwa kwezinto ezibonakalayo luxazululwe kakhulu lolu hlobo lokuqhekeka.
b. Ukuqhekeka kwengcindezi ye-mehendic Lolu hlobo lokuqhekeka luphinyiselwe ngokwengeziwe emigodini yangaphandle yezintambo zensimbi ezinkulu zensimbi.

2.1 Ithonya lekhebulaItheyiphu yensimbiUkwakheka
Kumakhebuli anezinhlamvu ezinkulu zangaphandle, ungqimba olunezikhali ngokuvamile lwakhiwa ngovalo lwensimbi enezinsimbi eziphindwe kabili. Kuya ngobubanzi obungaphandle kwentambo, ukuqina kwensimbi kuyahlukahluka (0.2mm, 0.5mm, no-0.8mm). Amateyipu wensimbi ahlanganisiwe anobunzima obuphakeme nobumpofu be-plastiki, okuholela ekuhlukaniseni okuphezulu phakathi kwezendlalelo eziphezulu nezingaphansi. Ngesikhathi sokukhishwa, lokhu kubangela umehluko obalulekile ekuqineni komgodi phakathi kwezendlalelo ezingenhla nezingaphansi zendawo ehlomile. Izindawo ze-Sheath ezincanyana emaphethelweni e-Outer Steel Tape isipiliyoni ngokugxilisa ingcindezi enkulu kunazo zonke futhi yizindawo eziyinhloko lapho kwenzeka khona ukuqhekeka kwesikhathi esizayo.
Ukunciphisa umthelela weteyipu yensimbi ehlomile ku-arter sheath, ungqimba olubukhali lobukhulu obuthile olusongwe noma lukhishwe phakathi kwetheyipu lensimbi kanye ne-peath yensimbi. Lesi singqimba esibuhlungu kufanele sibe mnene, ngaphandle kwemibimbi noma ama-protors. Ukungezwa kwesendlalelo se-buffering kuthuthukisa ubushelelezi phakathi kwalezi zingqimba ezimbili zetheyipu lensimbi, kuqinisekisa ubukhulu be-pepe, futhi, kuhlangene nokugqwayiza kwe-sheath ye-pe, kunciphisa ukucindezela kwangaphakathi.
I-OneWorld ihlinzeka abasebenzisi ngobukhulu obuhlukile beIzinto zensimbi zensimbi ezihlangene ze-talvanizedukuhlangana nezidingo ezahlukahlukene.
2.2 umthelela wenqubo yokukhiqiza ikhebula
Izinkinga eziyinhloko zenqubo yokukhishwa kwe-Extresion yamakhebula amakhemikhali anobude obukhulu abonakale kupholile, ukulungiselela okungafanele isikhunta, kanye nesilinganiso esengeziwe sokwelula, okuholela ekucindezelekeni okwedlulele ngaphakathi komgodi. Amakhebuli amakhulu asayizi, ngenxa yama-sheaths awo aminyene futhi abanzi, avame ukubhekana nemikhawulo ngobude kanye nomthamo wemikhombe yamanzi emigqeni yokukhiqiza ye-Extruon. Ukupholisa phansi kusuka kuma-degree angaphezu kwama-200 Celsius ngesikhathi sokudluliselwa ekushiseni kwegumbi kuba izinselelo. Ukupholisa okunganele kuholela emgqeni othambile eduze kwezembatho zezembatho, okubangela ukuklwebheka emgqeni we-sheath lapho ikhebula lihlanganiswe, ekugcineni kuphumela ekuqhekekeni kwamakhebula ngenxa yamabutho angaphandle. Ngaphezu kwalokho, ukupholisa okunganele kunomthelela ekukhulisweni kwamabutho angaphakathi akwa-Shrinkage ngemuva kokuhlanganisa, ukuphakalise ubungozi bokuqhekeka komhlanga ngaphansi kwamabutho angaphandle. Ukuqinisekisa ukupholisa ngokwanele, kwandisa ubude noma umthamo wemikhombe yamanzi. Yehlisa ijubane lokukhishwa ngenkathi ugcina i-sheath efanelekile yepulasitiki nokuvumela isikhathi esanele sokupholisa ngesikhathi sokuhlanganisa imali kubalulekile. Ngaphezu kwalokho, ngokubheka i-polyethylene njenge-crystalline polymer, indlela yokunciphisa izinga lokushisa elihlukanisiwe, ukusuka ku-70-75 ° C kuya ku-50-55 ° C, kusiza ukunciphisa izingcindezi zangaphakathi ngesikhathi senqubo yokupholisa.
2.3 Ithonya lokufaka imali ehlanganayo ekubizeni ikhebula
Ngesikhathi sokukholisa ikhebula, abakhiqizi banamathela emazingeni embonini ngokukhetha ama-reels okulethwa afanele. Kodwa-ke, ukuhlalisa ubude bokulethwa kwezikhathi zokulethwa kwamakhebuli amakhulu angaphandle kuba nezinselelo ekukhetheni ama-reels afanele. Ukuhlangabezana nobude obunqunyelwe ukulethwa, abanye abakhiqizi banciphisa ama-diameters we-reel barrel, okuholela ekuboleni okunganele ukubhala i-radii yekhebula. Ukugoba ngokweqile kuholela ekuchithweni kwezingalo zezembatho zezembatho zezembatho zezembatho, kubangela amandla amakhulu okugunda emgodini. Ezimweni ezinzima, ama-burrs ensimbi ahlomile angabhoboza ungqimba we-cushioning, ashukumise ngqo emgodini futhi adale imifantu noma imicibisholo eceleni komphetho wensimbi. Ngesikhathi sokubeka ikhebula, amabutho ahlanganayo okugoqa nokudonsela abamba umgoqo ukuthi aqhekeze ngalezi zinsimbi, ikakhulukazi amakhebuli asondelene nezingqimba zangaphakathi zikaRele, zibenza bathambekele ekuqhekekeni.
2.4 Umthelela wokwakhiwa kwesayithi nemvelo yokufaka
Ukuze uqinise ukwakhiwa kwamakhebula, kuyalulekwa ukuthi unciphise isivinini sokubeka ikhebula, ukugwema ingcindezi ye-lateral eyeqile, ukugoba, ukudonsa, ukudonsa kanye nokushayisana komhlaba, ukuqinisekisa indawo yokwakha empumputhe. Ngokuncono, ngaphambi kokufakwa kwentambo, vumela ikhebula ukuphumula ku-50-60 ° C ukukhipha ingcindezi yangaphakathi kusuka kumfutho. Gwema ukuvezwa isikhathi eside kwamakhebuli okuqondisa ukukhanya kwelanga, njengoba amazinga okushisa ahlukene ezinhlangothini ezahlukahlukene zekhebula kungaholela ekugxilisweni kwengcindezi, okwandisa ubungozi bokuqhekeka kwe-sheath ngesikhathi sekhebula.
