Crosslinked polyethylene: isicelo kanye nezici

Polyethylene sisetshenziselwa izinto esetshenziswa kulezo zimboni. Imikhiqizo kuwo nazo nokusetshenziswa ekuphileni kwansuku zonke. polyethylene Common azigcina amandla ayo 130 degrees. Nokho, ngokuvamile kuyadingeka ukuze ngisebenzise lokhu kokusebenza, futhi ezimweni ezimbi kakhulu ezingeni lokushisa eliphezulu nokucindezelwa, isibonelo kule bafudumale system futhi amanzi ashisayo.

Lesi sidingo ngokwengxenye kuye kwaholela search izindlela ukuthola impahla okuhlala isikhathi eside. ubuchwepheshe Found lavula polyethylene crosslinked, okuyinto has a isisindo esikhulu kuyisayensi yamangqamuzana ezinto ziqhathaniswa impahla ezivamile, futhi iye yathuthuka izici. Ngokuxhumanisa ukuqonda inqubo exhumanisa amangqamuzana ngenxa kumiswa cross-link axhunyiwe endaweni ngakuthathu igridi shirokoyacheistuyu.

Kuye imiphumela efakiwe ukuhlukanisa zamakhemikhali crosslinking ngokomzimba. Kulo mBhalo, igemfe (polyethylene cross-exhumene isetshenziswa ukudala izinto idatha) is zishiswe kuma-X ray eqinile. Lobu buchwepheshe iyakhiqiza impela, futhi umzuzu ungathola kufika ku-80 amamitha material.

A Ububi indlela ukuthi polyethylene crosslinked has ukujiya engalingani ipayipi. Ngo ingaphakathi uphendulela iphesenti aphansi kwakwakhe molecule e-ngaphandle, kunalokho, aphakeme. Ngakho, izindawo ezahlukene kanye nemikhiqizo ngobuningi. Imiphumela iba yinhlanganisela yokukhandleka crosslinked polyethylene isigaba C (PEX).

Uma usebenzisa indlela chemical ngoba esikhundleni sama-athomu ye-hydrogen e amangqamuzana asetshenziswa izidakamizwa silane ekhethekile. Ngakho-ke, silane crosslinked polyethylene. Ngo womshini amapayipi udlule okugeza ekhethekile egcwele izidakamizwa. Lokhu kuvumela ukwenza iyunifomu crosslinking inqubo evele kwangaphakathi futhi yangaphandle izindonga ipayipi ukujula. Lokhu ubuchwepheshe benza ukuthi ukuthola ipayipi nge iphesenti eliphezulu ukucubungula, futhi impahla esiqokiwe PEX-B.

Kukhona indlela kucutshungulwa polyethylene nitrogen ezizivelelayo impahla etholakala yakhethwa PEX-D. Nokho, lobu buchwepheshe awusebenzi ngenxa kahle ongaphakeme.

Futhi ukwenza peroxides cross-oxhumanisa. Kulokhu, inqubo ukukhiqizwa yakhiwa ukuxuba we peroxide kanye polyethylene ke usesimweni oncibilikisiwe nangaphansi lokushisa eliphezulu etholwe polyethylene crosslinked PEX-Iqembu.

Nokho, Amapayipi amakhulu izinto (amaqembu B, C) esetshenziselwa amanzi bafudumale, balinganiselwe eziningana ezihlobene ubunzima kanye nemikhiqizo ductility.

Impumelelo amaphayiphi eyenziwe polyethylene Iqembu, banayo amandla okusezingeni eliphezulu ukukhathala, crack ukumelana, ukuzinza ntathu, ukushintsha-shintsha, ukukhuthazela ukwethusa.

Ukushisisa PEX amapayipi kabanzi ukuze siqu, civil kanye nokwakhiwa ezimbonini. Ngosizo lwabo baphathe Floor kurediyetha isakhiwo bese udala uhlelo Ukushisa phansi.
