Intambo yamandla ye-crosslinesed inhlekile isetshenziswa kabanzi ohlelweni lwamandla ngenxa yezakhiwo zayo ezinhle ezishisayo nezemishini, izakhiwo zikagesi ezinhle kakhulu kanye nokuphikiswa kokugqwala kwamakhemikhali. Futhi inezinzuzo zesakhiwo esilula, isisindo esikhanyayo, ukubekwa kungakhawulelwe ngokwehla, futhi kusetshenziswa kabanzi kumagridi wamandla e-Urban Power, izimayini, izitshalo zamakhemikhali nezinye izigcawu. Ukufakwa kwentambo yekhebulai-polyethylene exhumene ne-cross, okuguqulwe ngamakhemikhali kusuka emugqeni moleculale polyethylene ehlelweni lenethiwekhi elinezici ezintathu, ngaleyo ndlela kuthuthukise kakhulu izakhiwo zemishini ze-polyethylene ngenkathi zigcina izakhiwo zayo ezinhle kakhulu zikagesi. Le mininingwane elandelayo umehluko kanye nezinzuzo phakathi kwamakhebuli we-polyethylene afakiwe nezintambo ezijwayelekile ezifakiwe ezivela ezicini eziningi.
1. Umehluko wezinto ezibonakalayo
(1) Ukumelana Nezinga lokushisa
Ukulinganiswa kokushisa kwezintambo ezijwayelekile ezifakiwe kuvame ukuba ngu-70 ° C.
(2) Umthamo ophethe
Ngaphansi kwendawo efanayo yesigaba sesiphambano, umthamo wokuthwala wamanje wekhebula le-XLPE elifakwe kuphakeme kakhulu kunalokho kwekhebula elijwayelekile elifakiwe, elingahlangabezana nohlelo oluningi lwamandla.
(3) Ububanzi besicelo
Izintambo ezijwayelekile ezifakiwe zizokhipha intuthu enobuthi ye-HCL lapho zishiswa, futhi azikwazi ukusetshenziswa ezimweni ezidinga ukuvimbela umlilo kanye nobuthi obuphansi. Ikhebula elihlanganiswe ne-polyethylene elihlanganisiwe alinayo i-halogen, enobungane obuningi, kufanelekile ukuthola amanethiwekhi okusabalalisa, ukufakwa kwezimboni kanye nezinye izimo ezidinga ukuhanjiswa kwamandla amakhulu, ikakhulukazi ama-voltage 6kv ~ 35kv ahleliwe ukuhambisa ukuhanjiswa kanye nemigqa yokusabalalisa.
(4) Ukuqina kwamakhemikhali
I-Crossinked PolyethYlene inokuphikiswa okuhle kwamakhemikhali futhi ingagcina ukusebenza okuhle emvelweni yama-acid, i-alkali kanye namanye amakhemikhali, okwenza kulungele ukusetshenziswa ngezimo ezikhethekile njengezindawo zamakhemikhali kanye nezindawo zasolwandle.
2. Izinzuzo zekhebula elixhumene ne-polyethylene elihlanganisiwe
(1) Ukumelana nokushisa
I-crossinked polyethylene iguqulwa ngezindlela zamakhemikhali noma zomzimba ukuguqula isimo se-molecular eqondile sibe isakhiwo senethiwekhi enezici ezintathu, esithuthukisa kakhulu ukumelana nokushisa kwezinto ezibonakalayo. Uma kuqhathaniswa ne-polyethylene evamile kanye ne-polyvinyl chloride insulation, amakhebula we-polyethylene awela ama-polyethylene aqinile ezindaweni eziphakeme zokushisa.
(2) Izinga lokushisa elisebenzayo
Izinga lokushisa lomqhubi wesifundo alinganiselwe lingafinyelela ku-90 ° C, eliphakeme kunaleso sendabuko yendabuko ye-PVC noma ye-polyethylene efakiwe, ngaleyo ndlela ngcono kakhulu ukuphepha kwamanje kwentambo nokuphepha okusebenzayo kwesikhathi eside.
(3) Izakhiwo eziphakeme zemishini
Intambo ye-polyethylene ye-crosslinesened isenezinto ezinhle kakhulu ze-thermo-mechanical ekushiseni okuphezulu, ukusebenza okungcono kokuguga, futhi kungagcina ukuqina kwemishini endaweni yokushisa ephezulu isikhathi eside.
(4) isisindo esikhanyayo, ukufakwa okulula
Isisindo sekhebula elixhumene ne-polyethylene elihlanganisiwe lilula ukwedlula lezo zezintambo ezijwayelekile, futhi ukubekwa akunqunyelwe yi-Drop. Ilungele ikakhulukazi izindawo eziyinkimbinkimbi zokwakha kanye nezimo ezinkulu zokufaka ikhebula.
(5) Ukusebenza okungcono kwezemvelo:
Intambo exhumekile ye-polyethylene ye-polyethylene ye-polyethylene ayinayo i-halogen, ayikhiphi amagesi anobuthi ngesikhathi sokuhlangana, ayinamthelela omncane emvelweni, futhi ilungele ikakhulukazi izindawo ezinezidingo eziqinile zokuvikelwa kwemvelo.
3. Izinzuzo ekufakweni nasekulungiseni
(1) Ukuqina okuphezulu
Intambo ye-polyethylene ye-crossinked efakwe i-anti-age-agulad, efanelekile ukubeka noma ukuvezwa kwemvelo yesikhathi eside, ukunciphisa imvamisa yokubuyiselwa kwamakhebula.
(2) Ukwethenjwa okuqinile kokufakelwa
Izakhiwo ezihle kakhulu zokufakwa kwe-polyethylene ewelekile, ngokumelana namandla aphezulu voltage kanye namandla okuqhekeka, ukunciphisa ubungozi bokuhluleka ukufaka izicelo kuzicelo eziphakeme ze-voltage.
(3) izindleko eziphansi zokulungiswa
Ngenxa yokumelana nokuqina kokuphikiswa kanye nokuphikiswa kokuguga kwezintambo ze-polyethylene ezifakiwe, impilo yabo yenkonzo ikude, yehlisa izindleko zansuku zonke kanye nezindleko zokubuyiselwa.
4. Izinzuzo zokusekelwa okusha kwezobuchwepheshe
Eminyakeni yamuva nje, ngokuthuthuka kobuchwepheshe bezinto ezibonakalayo ze-polyethylene, ukusebenza kwalo kanye nezindawo ezibonakalayo kuthuthukisiwe, njengokuthi:
I-Flame Retame ethuthukisiwe, ingahlangana nezindawo ezikhethekile (ezinjengesitimela, isiteshi sesiteshi);
Ukuhanjiswa okubandayo okuthuthukisiwe, kusazinza esimeni esindayo esibi kakhulu;
Ngenqubo entsha yokunqamula, inqubo yokukhiqiza amakhebula isebenza kahle futhi inobungani bemvelo.
Ngokusebenza kwayo okuhle kakhulu, izintambo ezixhumene ne-polyethylene ezihlangene ezingena endaweni ebalulekile emkhakheni wokudluliselwa kwamandla nokusatshalaliswa, ukuhlinzeka ngokukhethwa okuphephile, okuthembekile futhi okunobungani kwezemvelo kwamagridi anamuhla asemadolobheni kanye nentuthuko yezimboni.
