Imiterere ya kabili isa nkaho yoroshye, mubyukuri, buri kintu kigize gifite intego yacyo cyingenzi, bityo buri kintu cyigice kigomba gutoranya neza mugihe cyanditseho umugozi, kugirango habeho kwizerwa muri ibyo bikoresho mugihe cyo gukora.
1. Ibikoresho bishinzwe
Amateka, ibikoresho bikoreshwa kumashanyarazi byari umuringa na aluminium. Sodium nayo yageragejwe na gato. Umuringa na aluminium bafite imishinga y'amashanyarazi meza, kandi ingano yumuringa ni mikeya mugihe cyo kohereza ibigezweho, bityo diameter yo hanze yuyobora umuringa ni ntoya. Igiciro cya aluminium kirenze umuringa. Byongeye kandi, kubera ko ubucucike bw'umuringa bunini kuruta icya Aluminiyumu, nubwo ubushobozi bwo gutwara ibintu ari bumwe, umugozi wambukiranya umuyoboro wa aluminiyumu kuruta uwuyobora uruta.
2. Ibikoresho byo kwikinisha
Hariho ibikoresho byinshi bikubiyemo MV insinga zingufu za MV zishobora gukoresha, ndetse zirimo tekinoroji yibikoresho byimpapuro zidasanzwe, bikoreshwa neza mumyaka irenga 100. Uyu munsi, abasulake bagaragaye ko byemewe cyane. Ibikoresho byo kwigishaho Polymer birimo pe (ldpe na hdpe), xlpe, wtr-xlpe na epr. Ibi bikoresho ni thermostique kimwe no kuri trarmoseting. Ibikoresho byo mu mubiri bihinduka iyo gushyuha, mugihe ibikoresho bya thermosese bigumana imiterere yubushyuhe bwo gukora.
2.1. Urupapuro
Ku ntangiriro yimikorere yabo, insinga zuzuye impapuro zitwara umutwaro muto kandi ukomeza kubungabungwa neza. Nyamara, abakoresha imbaraga bakomeje gukora umugozi mwinshi kandi mwinshi, imiterere yumwimerere yo gukoresha ntabwo ikwiriye gukenera umugozi uriho, noneho uburambe bwiza bwambere ntibushobora guhagararira imikorere yumwanya wa kabili bugomba kuba bwiza. Mu myaka yashize, impapuro zuzuye insinga zakoreshejwe gake.
2.2.Pvc
PVC iracyakoreshwa nkibintu bifatika kubikoresho bito-voltage 1kv kandi nabyo ni ibintu byinshi. Ariko, gusaba PVC mubiganiro bya kabili bisimburwa byihuse na xlpe, kandi gusaba muri lilyethylene (LELPE) cyangwa ubucucike bwa polyethylene (MDPE) cyangwa insinga zidasanzwe, hamwe nubutaka buke bwikiguzi cyo hasi.
2.3. Polyethylene (pe)
Ubucucike buke Polyethylene (LDPE) yakoreshwaga nka shingiro rya polyethylene (Xlpe) hamwe nigiti kirwanya amazi yambukiranya polyethylene (Wtr-Xlpe) ibikoresho. Muri leta ya thermoplastique, ubushyuhe ntarengwa bwo gukora bwa polyethylene ni 75 ° C, iri munsi yubushyuhe bwimpapuro insinga zuzuye (80 ~ 90 ° C). Iki kibazo cyakemuwe hamwe no kugaruka kwa polyethylene (Xlpe), ishobora guhura cyangwa kurenza ubushyuhe bwa serivisi bwimigozi yimpapuro.
2.4.Crotethylene (Xlpe)
Xlpe ni ibikoresho bya theruset bikozwe mukuvanga-ubucucike bwa polyethylene (ldpe) hamwe numukozi wambukiranya (nka peroxide).
Umuyobora ntarengwa ukora ubushyuhe bwa Xlpe yizewe 90 ° C, ikizamini kirenze urugero kigera kuri 140 ° C. XLPE ifite ibiranga 250 °
2.5. Igiti kirwanya amazi cyambukiranya polyethylene (wtr-xlpe)
Ibiti byamazi bizagabanya ubuzima bwa serivisi ya Xlpe. Hariho inzira nyinshi zo kugabanya imikurire y'ibiti by'amazi, ariko imwe mukemerwa cyane ni ugukoresha ibikoresho byo kugira ngo bigerweho bidasanzwe byo gukura kw'ibiti, byitwa igiti kirwanya amazi yambukiranya amazi ya polyethlene wtr-xlpe.
2.6. Ethylene Propaylene Rubber (EPR)
EPR ni ibintu bikoresho bikozwe muri Ethylene, propylene (rimwe na rimwe umuhanga wa gatatu), na copolymer ya monomer eshatu yitwa Ethylene Propaylene Diene Diene Rubber (EPDM). Hejuru yubushyuhe bwinshi, EPR buri gihe ikomeza kuba yoroshye kandi ifite ubuhanga bwiza bwa corona. Ariko, gutakaza imishinga yibikoresho bya EPR biruta cyane kurenza xlpe na wtr-xlpe.
3. Ubugenzuzi buke
Inzira yo kwambukiranya irihariye kuri polymer yakoreshejwe. Gukora polymes yambukiranya abantu bitangirana na matrix polymer hanyuma bigasindagaje kandi tros transkers zongeweho kugirango zibe imvange. Gahunda yo kwambukiranya yongeraho ingingo nyinshi kumiterere ya molecular. Iyo umusanzu umaze guhuzwa, urunigi rwa polemer ruguma ahantu hose, ariko ntushobora gucibwa burundu amazi ashonga.
4. Umuyobora ukingira kandi akinga ibikoresho bigize
Igice cya kabiri gikingira kumurongo uhagaze hanze yuyobora no kwinjiza kwagura amashanyarazi no kubamo amashanyarazi muri kabili yagejejwe. Ibi bikoresho birimo urwego rwubwubatsi rwa karubone kugirango ushoboze umugozi wikingira kugirango ugere ku muco uhamye kugirango ugere kumurongo usabwa.
