PE ipayipi izakhiwo eziningana ezikhethekile

1.PE izici zokumelana nokugqwala kwepayipi?

I-Polyethylene iyinto engasebenzi engamelana nokugqwala kwemithombo yamakhemikhali ehlukahlukene.Akukho ukugqwala kwe-electrochemical, akukho ungqimba oluphikisana nokugqwala.

2. Izici ezingavuzi ze-PE tube?

Ipayipi le-polyethyleneikakhulukazi ithatha uxhumano lwe-welding (uxhumano olushisayo lwe-fusion noma uxhumano lwe-electric fusion), okuqinisekisa ngokuyisisekelo ubunikazi be-interface material, isakhiwo kanye nomzimba wepayipi, futhi eqaphela ukuhlanganiswa kwejoyinti nepayipi.Ukuhlolwa kufakazela ukuthi amandla aqinile namandla okuqhuma kwesixhumi esibonakalayo aphezulu kunalawo omzimba wepayipi, futhi ayikho inkinga yokuvuza uma kuqhathaniswa namajoyinti enjoloba noma amanye amalunga emishini.

Ipayipi le-3.PE izici zokuqina okuphezulu?

Ipayipi le-polyethylene liwuhlobo lwepayipi lokuqina okuphezulu, ubude bayo ngesikhathi sekhefu ngokuvamile bungaphezu kuka-500%, ikhono lokuzivumelanisa nokuhlaliswa okungalingani kwesisekelo sepayipi kunamandla kakhulu.Futhi kuwuhlobo lwepayipi olusebenza kahle kakhulu ngokumelene nokuzamazama komhlaba.Ngo-1995 ukuzamazama komhlaba e-Kobe e-Japan, ipayipi legesi le-polyethylene kanye nepayipi lokuhlinzeka ngamanzi yisistimu yamapayipi ayilondoloziwe.Ngakho-ke, iJapane ngemva kokuzamazama komhlaba ikhuthaza ngamandla ukusetshenziswa kwepayipi le-PE emkhakheni wegesi.

I-4.PE tube inezici ezinhle kakhulu eziguquguqukayo?

Ukuguquguquka kwe-polyethylene kuvumela amapayipi e-polyethylene ukuthi aphindwe futhi ahlinzekwe ngobude obude ngaphandle kwesidingo sezinhlobonhlobo zokuhlanganiswa okuhlangene.Ngokwakhiwa okungenazintambo, isiqondiso sepayipi le-polyethylene singashintshwa kalula ngokuvumelana nezidingo zendlela yokwakha, futhi ubukhulu bokuqala nobukhulu kungabuyiselwa ngemva kokwakhiwa.

5. Ungaziqonda kanjani izici ze-PE tube enokumelana okuhle nemihuzuko?

Ukuklwebheka kubangela ukugxila kokucindezeleka ezintweni, okuholela ekuhlulekeni kwepayipi.Lapho kusetshenziswa ubuchwepheshe obungenamibhoshongo, kunzima kakhulu ukugwema ukuklwebheka, kungakhathaliseki ukuthi kufakwe ipayipi elisha noma kushintshwa ipayipi elidala.Eminyakeni yamuva nje, kuye kwafakazelwa ukuthi ipayipi le-polyethylene le-PE80 linokumelana okungcono nokukhula kancane kokuqhekeka nokumelana nokuklwebheka, futhi ipayipi le-polyethylene le-PE100 linokumelana okungcono nokuklwebheka.Ngakho-ke, ipayipi le-polyethylene lisetshenziswa kabanzi ekwakhiweni kobuchwepheshe be-trenchless.

6. Ipayipi le-PE linezici zokumelana okuhle kokudlulisa ukuqhekeka okusheshayo.

Ukuqhekeka ngokushesha kwepayipi kuwuhlobo lwengozi yengozi.Umfantu ukhula ngokushesha ngesivinini esithile, okubangela ukugqabuka kwamapayipi angamashumi amamitha noma izinkulungwane zamamitha amapayipi ngaso leso sikhathi, futhi umphumela uba yinhlekelele.Ekuqaleni kwawo-1950, kwaba nezingozi ezimbalwa eziqhekeka ngokushesha epayipini legesi lase-United States.Ukuqhekeka okusheshayo kwepayipi legesi le-polyethylene akutholakalanga ekusebenzeni.Eminyakeni yamuva nje, kuye kwenziwa ucwaningo oluningi mayelana nokuqhekeka okusheshayo kwamapayipi emhlabeni.Imiphumela ibonisa ukuthi ukumelana kwepayipi le-polyethylene ekusakazeni ukuqhekeka kuphakathi kokuhle kakhulu.
