Ibikoresho by'insinga na kabili birashobora kugabanywamo ibikoresho bitwara ibintu, ibikoresho byokwirinda, ibikoresho birinda, ibikoresho byo gukingira, ibikoresho byuzuza nibindi ukurikije ibice n'imikorere yabyo.Ukurikije ibintu bifatika, irashobora kugabanywamo ibyuma (umuringa, aluminium, aluminiyumu, ibyuma), plastike (PVC, PE, PP, XLPE / XL-PVC, PU, ​​TPE / PO), reberi, nibindi ariko bimwe muri ibyo bikoresho birasanzwe muburyo butandukanye.Cyane cyane ibikoresho bya termoplastique, nka polyvinyl chloride, polyethylene, mugihe cyose ihinduka ryibice bya formula rishobora gukoreshwa mugukingira cyangwa gukata.

Ibikurikira, tumenyekanisha insinga zisanzwe zitari ibyuma hamwe nibikoresho fatizo

Imwe, polyvinyl chloride (PVC)

PVC isanzwe ikoreshwa nkibikoresho byo gukingira.PVC nk'imikorere ya insinga na insinga: ntabwo byoroshye gutwika, kurwanya gusaza, kurwanya amavuta, kurwanya imiti, kurwanya ingaruka, amabara yoroshye;Nyamara, kubera nini nini ya dielectric ihoraho, mubisanzwe ikoreshwa gusa nkibikoresho byo kubika insinga ya voltage ntoya na kabili yo kugenzura.

PVC nk'imigozi y'insinga n'insinga: hamwe no kurwanya kwambara neza, kurwanya amavuta, aside, alkali, bagiteri, ubushuhe n'izuba, hamwe nibikorwa bya flame bifite imikorere yo kuzimya;Icyatsi cya PVC gifite ubushyuhe buke bwo gukora -40 ° C hamwe nubushyuhe bwo hejuru bwa 105 ° C.

Babiri, polyethylene (PE)

PE ibintu rusange bifatika: ibishashara byera, byoroshye, byoroshye kandi bikomeye, birashobora kurambura gato, urumuri kuruta amazi, ntabwo ari uburozi;Ibiranga gutwikwa: gutwikwa, kuva mumuriro kugirango ukomeze gutwika, impera yo hejuru yumuriro ni umuhondo naho impera yo hepfo ni ubururu, gushonga gutonyanga iyo byaka, gutanga impumuro yo gutwika paraffine;Polyethylene itunganya gushonga ni 132 ~ 1350C, ubushyuhe bwo gutwika ni 3400C, ubushyuhe bwihuse ni 3900C.

Polyethylene (PE) muri rusange igabanijwemo LDPE, MDPE, HDPE, FMPE ibyiciro byinshi.

1. imbaraga zikomeye.Umuvuduko muke wa polyethylene ufite imbaraga zubukanishi, kurwanya ubushyuhe buke, kandi, kandi, intege nke zigaragara ni ukurwanya nabi ibidukikije.

2.

3. yazamuye imyuka y'amazi hamwe na barrière ya barrière, guhangana nibidukikije byangiza ibidukikije birarenze.

4, FMPE: ifuro rya PE ni ibikoresho bikoreshwa cyane, bifashishije polyethylene yimiti, imiti ihoraho ya dielectric irashobora kugabanuka kugera kuri 1.55.Niba tekinolojiya mishya yo gukoresha ifuro ifatika, ni ukuvuga, iyo gusohora gaze ya gaze (azote cyangwa umwuka) mu ifuro rya polyethylene yashongeshejwe, ingano ntoya y’ibishobora kuboneka mu ifuro rya polyethylene, impumu irashobora kugenzurwa hagati ya 35-40 %, hejuru ya 40% Zhui, ihoraho ya dielectric irashobora kugabanuka kugera kuri 1.20 cyangwa irenga, kandi kubera ko idakoresha imiti ifata imiti, insulasiyo ntabwo irimo ibisigazwa byabashitsi, kandi igihombo cya dielectric kirashobora kugabanuka cyane, cyageze urwego rwo guhumeka ikirere.

Polyethylene ifite imikorere myiza yamashanyarazi kandi ikoreshwa cyane mugutumanaho insinga.Kugirango tunoze ibipimo bya tekiniki nubukungu byinsinga zitumanaho, muri rusange polyethylene ikoreshwa.Kugirango tunoze imikorere yibidukikije byangiza ibidukikije, usibye gukoresha XPE, birashobora kandi guhitamo gushonga kwa PE nto.Mubisanzwe, uburemere buke bwa molekuline (niko urwego rwo hejuru rushonga), niko bigenda byangiza ibidukikije.Igipimo cyo gushonga kiri munsi ya 0.4 kirashobora ahanini kwirinda guhagarika ibidukikije.Ubucucike bwa 0.950, igipimo cyo gushonga cyubwoko buto, burwanya cyane ihungabana ry’ibidukikije.Niba ubucucike burenze 0,95, guhangana n’ibidukikije byangiza ibidukikije nabyo ni bibi, ariko ubucucike bwo hasi hamwe nigipimo kimwe cyo gushonga nibyiza cyane.Nyamara, gushushanya kwa HDPE akenshi bifite ibibazo bisigaye byimbere, bigomba kwitabwaho mugikorwa cyo gukoresha.

Kuvanga PE na EVA muburyo runaka birashobora guteza imbere ihungabana ryibidukikije;Kuvangwa na PP birashobora kunoza ubukana;Ivanze na PE yubucucike butandukanye, irashobora guhindura ubworoherane nubukomere.

Ethylene - vinyl acetate copolymer (EVA)

EVA ni ubwoko bwa thermoplastique hamwe na elastike nka nuo rubber, imikorere yayo nibiri muri vinyl acetate (VA) bifitanye isano ikomeye: ntoya VA isa na polyethylene yumuvuduko ukabije, kandi nuburyo VA isa na reberi.EVA nuo umuvuduko mwinshi polyethylene hamwe na VA nkeya, yoroshye ningaruka nziza zingirakamaro, ibereye gukora ibikoresho byinshi.

EVA ifite ubuhanga bworoshye nubushyuhe buke, kurwanya imiti, kurwanya ikirere, hamwe na LDPE copolymerisation, birashobora kunoza ibidukikije byangiza ibidukikije bya LDPE, kurwanya ingaruka, gukomera no gufatana hagati yuyobora no kwikingira.

Tetrapolypropylene (PP)

Uburemere bwihariye bwa polypropilene ni 0.89 kugeza 0,91, aribwo buto muri plastiki zisanzwe.Ifite imbaraga zubukanishi, ubushyuhe bworoshe cyane muri resimoplastique, hamwe nubushyuhe buke bwo kurwanya no gusaza.Gusa optique yo guhinduranya irwanya ubukene gato, ariko irashobora kunozwa na copolymerisation hamwe na stabilisateur.

Ibintu rusange bya polypropilene: ISOKO ya PP irasa cyane na HDPE, ni igishashara cyera gikomeye, kibonerana kurusha PE, kidafite uburozi, cyaka kandi kizakomeza gutwikwa nyuma yumuriro, kandi kirekure impumuro ya peteroli nuo.

Ugereranije na polyethylene, polypropilene ifite ibintu bitandukanye bikurikira:

1, Ubuso bwa PP burenze hejuru ya PE, kwambara birwanya no kugorora ubushobozi bwo guhindura ibintu nibyiza cyane, PP rero izwi nka "plastike yubucucike buke cyane plastike".

2, PP iruta PE ikindi kintu cyiza ntakibazo gihari cyo guhagarika ibidukikije, PP ifite imbaraga zo kurwanya ihungabana ryibidukikije.Nyamara, kubera ubwinshi bwimiterere ya molekulire ya PP, imikorere yayo mubushyuhe bwicyumba nubushyuhe buke ni bibi cyane.

3, THE amashanyarazi yimikorere ya PP: PP nibikoresho bidafite inkingi, kubwibyo hariho amashanyarazi meza.

Gukwirakwiza amashanyarazi ahanini bisa na LDPE, kandi ntabwo bihinduka mumurongo mugari.Bitewe n'ubucucike buke cyane, dielectric ihoraho ni ntoya kuruta LDPE (ε = 2.0 ~ 2.5), igihombo cya dielectric Angle tangent ni 0.0005 ~ 0.001, ubukana bwa 1014 ω.M, gusenya umurima imbaraga nazo ziri hejuru cyane, 30MV / m;Byongeye kandi, kwinjiza amazi ni bito cyane, PP rero irashobora gukoreshwa nkibikoresho byo hejuru cyane.

Ibikoresho bitanu bya polyester

Ubu bwoko bwibikoresho burangwa na modulus nyinshi, irwanya amarira menshi, irwanya kwambara cyane, elastique nyinshi hamwe nubukererwe buke, urugero rwo hejuru rwubushyuhe bukurikizwa ni 1500C, cyane kuruta izindi reberi ya termoplastique, ariko kandi ifite amavuta meza yo kurwanya amavuta, irwanya ibishishwa ibiranga.
