Incazelo yemigqa yokumaka yamapayipi e-PE ngemibala ehlukene

Abantu abavame ukusebenzisaIpayipi le-PEukwakhiwa yazi lokhoIpayipi le-PEubuso bunemigqa elinganayo enombala ofanayo, oluhlaza okwesibhakabhaka, ophuzi, obomvu, ngakho kusho ukuthini?Emakethe yamapayipi kamasipala waseShayina, ipayipi lokuphakela amanzi kanye nepayipi legesi yizimakethe ezimbili ezinkulu zokufaka izicelo.Igama lesiShayina lamakhemikhali e-PE, i-polyethylene, impahla ye-PE ngenxa yamandla ayo aphezulu, ukumelana nokushisa okuphezulu, ukumelana nokugqwala, okungezona ubuthi, ukumelana nokugqoka nezinye izici, isetshenziswa kabanzi emkhakheni wokukhiqiza amanzi kanye nokukhiqiza amanzi.Ngoba ngeke igle, ngakho-ke iyipayipi ekahle yokushintsha ipayipi elivamile lokuhlinzeka ngamanzi ensimbi;Ngokusho kokusetshenziswa kwayo, ubuso be-tube ye-PE buhlukaniswa ngemigqa ehlukene yokumaka imibala.Imibala elandelayo imele ukusetshenziswa okuningana ngokulandelana:

1.Umugqa wamaka obomvu: Ipayipi lemayini ye-PE

Phakathi kwawo wonke amapulasitiki obunjiniyela, ukumelana nokugqokwa kwe-HDPE kuthatha umqhele wamapulasitiki, okudonsa amehlo.Ukuphakama kwesisindo se-molecular of the material, yilapho imelana kakhulu, ngisho nangaphezu kwezinsimbi eziningi (njenge-carbon steel, insimbi engagqwali, ithusi, njll.).Ngaphansi kwesimo sokugqwala okuqinile nokugqoka okuphezulu, impilo yayo yesevisi iphindwe izikhathi ezingu-4-6 kunepayipi lensimbi kanye nezikhathi ezingu-9 kune-polyethylene evamile.Futhi uthuthukise ukusebenza kahle kokudlulisela ngo-20%.

I-flame retardant, ukusebenza kwe-antistatic kuhle, konke kuhlangabezana nezidingo ezijwayelekile.Impilo yesevisi ye-Downhole iminyaka engaphezu kwengu-20, izinzuzo zezomnotho eziphawulekayo, ukumelana nomthelela, ukumelana nokugqoka, umphumela wokumelana kabili.

2.Umugqa oluhlaza:Ipayipi lokuphakela amanzi le-PE, ipayipi lokudonsa amanzi, nepayipi lomlilo

Ipayipi le-PE blowdown: Ipayipi le-PE elisetshenziselwa i-blowdown libizwa nangokuthi ipayipi le-polyethylene ephezulu, okuyi-HDPE ngesiNgisi.Lolu hlobo lwamapayipi luvame ukusetshenziswa njengepayipi likamasipala lobunjiniyela, elisetshenziswa kakhulu: embonini yokuhlanza indle.Ngenxa yokumelana nokugqokwa kwayo, ukumelana ne-asidi, ukumelana nokugqwala, ukumelana nokushisa okuphezulu, ukumelana nomfutho ophakeme nezinye izici, kancane kancane iye yashintsha indawo yepayipi lensimbi lendabuko, ipayipi likasimende namanye amapayipi emakethe, ikakhulukazi ngoba ipayipi lilula isisindo futhi kulula ukuyifaka nokuhambisa, kuyisinqumo esingcono kakhulu sezinto ezintsha.

Ipayipi lamanzi le-PE: Ipayipi le-PE lokuphakelwa kwamanzi liwumkhiqizo oshintshwayo wepayipi lensimbi lendabuko kanye nepayipi lamanzi okuphuza le-PVC.Ipayipi lamanzi kufanele lithwale ingcindezi ethile, ngokuvamile likhethe isisindo esiphezulu samangqamuzana, izakhiwo ezingcono zemishini ye-PE resin, njenge-HDPE resin.I-LDPE resin inamandla aphansi okudonsa, ukumelana nokucindezela okubi, ukuqina okubuthakathaka, ukuzinza okungalungile kwe-dimensional lapho yakha futhi icutshungulwa, nokuxhumeka okunzima, ayifaneleki njengempahla yepayipi lokucindezela kwamanzi.Kodwa-ke, ngenxa yenkomba yayo ephezulu yezempilo, i-PE, ikakhulukazi i-HDPE resin, isibe yinto evamile ekukhiqizeni amapayipi amanzi okuphuza.I-HDPE resin ine-viscosity encane encibilikayo, i-fluidity enhle nokucubungula okulula, ngakho-ke uhla lokukhetha lwenkomba yalo yokuncibilika lubanzi, ngokuvamile i-MI phakathi kuka-0.3-3g/10min.

3.Ulayini welebula ophuzi: Ipayipi legesi le-PE

Ipayipi le-PE legesi liwumkhiqizo oshintshwayo wepayipi lensimbi yendabuko kanye negesi ye-PVC.

Ipayipi legesi kufanele lithwale ingcindezi ethile, ngokuvamile likhethe isisindo esikhulu samangqamuzana, izakhiwo ezinhle zemishini ye-PE resin, njenge-HDPE resin.I-HDPE resin inamandla aphansi okudonsa, ukumelana nokucindezela okubi, ukuqina okubuthakathaka, ukuzinza okungalungile kwe-dimensional lapho yakha, nokuxhumeka okunzima, ayifaneleki njengempahla yepayipi lokucindezela kwamanzi.Kodwa-ke, i-LDPE, ikakhulukazi inhlaka ye-LLDPE, isiphenduke into esetshenziswa kakhulu ipayipi legesi ngenxa yenkomba yayo ephezulu yezempilo.I-LDPE, i-LLDPE resin melt viscosity incane, i-fluidity enhle, ukucubungula okulula, ngakho-ke uhla lokukhetha lwenkomba yalo yokuncibilika lubanzi, ngokuvamile i-MI phakathi kuka-0.3-3g/10min.
