Itandukaniro hagati ya Polyethylene Ihuza Intsinga Zisanzwe hamwe ninsinga zisanzwe

Umuyoboro w'amashanyarazi wahujwe na polyethylene ukoreshwa cyane muri sisitemu y'amashanyarazi kubera imiterere myiza yubushyuhe nubukanishi, ibikoresho byiza byamashanyarazi hamwe no kurwanya ruswa. Ifite kandi ibyiza byuburyo bworoshye, uburemere bworoshye, gushyira ntabwo bigarukira kumanuka, kandi bikoreshwa cyane mumashanyarazi yo mumijyi, ibirombe, inganda zimiti nibindi bice. Gukingira umugozi ukoreshaguhuza polyethylene, ihindurwa muburyo bwa chimique iva kumurongo wa molekuline polyethylene ikagira imiyoboro itatu-yimiterere, bityo igatezimbere cyane imiterere ya polyethylene mugihe ikomeza ibintu byiza byamashanyarazi. Ibikurikira birambuye itandukaniro ninyungu hagati ya polyethylene ihujwe ninsinga zisanzwe hamwe ninsinga zisanzwe zifunze kuva mubice byinshi.

1. Itandukaniro ryibintu

(1) Kurwanya ubushyuhe
Igipimo cy'ubushyuhe bw'insinga zisanzwe zisanzwe ni 70 ° C, mu gihe igipimo cy'ubushyuhe cy’imigozi ya polyethylene ihujwe n’insinga zishobora kugera kuri 90 ° C cyangwa hejuru yacyo, bikazamura cyane ubushyuhe bw’umuriro wa kabili, bigatuma bikenerwa ahantu hakorerwa imirimo ikaze.

(2) Gutwara ubushobozi
Munsi yumurongo umwe uhuza ibice, ubushobozi bwo gutwara insinga ya XLPE iruta kure cyane iy'umugozi usanzwe ukingiwe, ushobora kuzuza sisitemu yo gutanga amashanyarazi hamwe nibisabwa muri iki gihe.

(3) Ingano yo gusaba
Intsinga zisanzwe zifunguye zizarekura umwotsi wubumara wa HCl mugihe utwitswe, kandi ntushobora gukoreshwa mubihe bisaba gukumira inkongi yumuriro nuburozi buke. Umugozi wambukiranya polyethylene ntushobora kubamo halogene, yangiza ibidukikije, ibereye imiyoboro ikwirakwizwa, inganda n’inganda zindi zisaba amashanyarazi menshi, cyane cyane AC 50Hz, igipimo cya voltage 6kV ~ 35kV cyagenwe cyo gukwirakwiza no gukwirakwiza.

(4) Imiti ihamye
Polyethylene ihujwe ifite imiti irwanya imiti kandi irashobora gukomeza gukora neza mubidukikije bya acide, alkalis nindi miti, ibyo bigatuma ikoreshwa neza mubihe bidasanzwe nkibimera byimiti n’ibidukikije byo mu nyanja.

2. Ibyiza bya kaburimbo ihuza polyethylene

(1) Kurwanya ubushyuhe
Polyethylene ihujwe ihindurwa nuburyo bwa chimique cyangwa physique kugirango ihindure imiterere ya molekulari yumurongo muburyo bwimiterere yibice bitatu, biteza imbere cyane ubushyuhe bwibintu. Ugereranije na polyethylene isanzwe hamwe na chloride ya polyvinyl, insinga za polyethylene zuzuzanya zirahagaze neza mubushyuhe bwo hejuru.

(2) Ubushyuhe bwo hejuru bwo gukora
Ubushyuhe bwo gukora bwa kiyobora bushobora kugera kuri 90 ° C, bukaba burenze ubw'imigozi gakondo ya PVC cyangwa polyethylene, bityo bikazamura cyane ubushobozi bwo gutwara insinga n'umutekano muremure.

(3) Ibikoresho byo mu rwego rwo hejuru
Umuyoboro wa polyethylene uhujwe uracyafite ibintu byiza bya termo-mashini ku bushyuhe bwo hejuru, imikorere myiza yo gusaza neza, kandi birashobora gukomeza guhagarara neza mubushyuhe bwo hejuru mugihe kirekire.

(4) Uburemere bworoshye, kwishyiriraho byoroshye
Uburemere bwumugozi uhujwe na polyethylene insinga iroroshye kurenza iy'insinga zisanzwe, kandi gushira ntabwo bigarukira kumanuka. Birakwiriye cyane cyane kubidukikije bigoye byubatswe hamwe nini nini yo gushiraho insinga.

(5) Imikorere myiza y’ibidukikije:
Umugozi uhuza polyethylene wangiritse ntabwo urimo halogene, nturekura imyuka yubumara mugihe cyo gutwikwa, ntigira ingaruka nke kubidukikije, kandi irakwiriye cyane cyane ahantu hasabwa cyane kurengera ibidukikije.

3. Ibyiza mugushiraho no kubungabunga

(1) Kuramba cyane
Umuyoboro wa polyethylene uhujwe ufite ibikorwa byinshi byo kurwanya gusaza, bikwiranye no gushyingurwa igihe kirekire cyangwa guhura n’ibidukikije hanze, bikagabanya inshuro zo gusimbuza insinga.

(2) Kwizerwa gukomeye
Ibintu byiza cyane byokwirinda bya polyethylene bihujwe, hamwe n’umuvuduko mwinshi wa voltage hamwe nimbaraga zo gusenyuka, bigabanya ibyago byo kunanirwa kwizana mubisabwa na voltage nyinshi.

(3) Amafaranga yo kubungabunga make
Bitewe no kwangirika kwangirika no kurwanya gusaza kwinsinga za polyethylene zifatanije, insinga zumurimo ni ndende, kugabanya kubungabunga buri munsi no gusimbuza ibiciro.

4. Inyungu zinkunga nshya ya tekiniki

Mu myaka yashize, hamwe nogutezimbere tekinoloji yibikoresho ya polyethylene ihuriweho, imikorere yayo yo kubika hamwe nibintu bifatika byarushijeho kunozwa, nka:
Kuzamura flame retardant, birashobora kuzuza ahantu hihariye (nka metero, sitasiyo yumuriro) ibisabwa byumuriro;
Kunoza ubukonje bukonje, buracyahagaze neza mubukonje bukabije;
Binyuze muburyo bushya bwo guhuza, inzira yo gukora insinga irakora neza kandi yangiza ibidukikije.

Nibikorwa byayo byiza, insinga zahujwe na polyethylene zifite insinga zifite umwanya wingenzi mubijyanye no guhererekanya amashanyarazi no gukwirakwiza, bitanga amahitamo meza, yizewe kandi yangiza ibidukikije kumashanyarazi agezweho yo mumijyi no guteza imbere inganda.
