Polyethylene (PE) ikoreshwa cyane muinsinga z'amashanyarazi n'iz'itumanaho zishyirwa mu cyuma gikingira no gukingira insinga z'amashanyarazibitewe n'imbaraga zayo nziza za mekanike, gukomera kwayo, kudashyuha cyane, ubushyuhe bwayo, no kudahungabana mu mikorere yayo. Ariko, bitewe n'imiterere ya PE ubwayo, kudahangana kwayo n'ingaruka mbi ku bidukikije ni bike cyane. Iki kibazo kigaragara cyane iyo PE ikoreshejwe nk'icyuma cyo hanze cy'insinga nini.
1. Uburyo bwo gucika kw'icyuma cya PE
Gucika kw'agahu ka PE bibaho cyane cyane mu bihe bibiri:
a. Gucikagurika kw'ibidukikije: Ibi bivuga ikintu aho agahu gacikagurika gaturutse hejuru bitewe n'imbaraga cyangwa kwibasirwa n'ibidukikije nyuma yo gushyiraho insinga no kuzikoresha. Biterwa ahanini n'imbaraga zo mu gahu no kwibasirwa n'amazi menshi aturuka ku mpande. Ubushakashatsi bwinshi ku guhindura ibintu bwakemuye cyane ubwo bwoko bw'icikagurika.
b. Gucikagurika k'umuvuduko w'amashanyarazi: Ibi bibaho bitewe n'imiterere mibi mu nsinga cyangwa inzira zitari nziza zo gusohora insinga, bigatuma habaho stress nyinshi no gucikagurika bitewe n'ihindagurika ry'imitsi mu gihe cyo gushyiraho insinga. Ubwo bwoko bw'icikagurika bugaragara cyane mu nsinga z'inyuma z'insinga nini zifite icyuma.
2. Impamvu zitera PE Sheath scratching no kunoza ingamba
2.1 Ingaruka za CableKaseti y'icyumaImiterere
Mu nsinga zifite umurambararo munini w'inyuma, urwego rw'icyuma rugizwe n'udupira tw'icyuma dufite urwego rubiri. Bitewe n'umurambararo w'inyuma w'insinga, ubunini bwa kaseti y'icyuma buratandukanye (0.2mm, 0.5mm, na 0.8mm). Kaseti z'icyuma zifite icyuma ziremereye zifite ubukana bwinshi kandi ntizikora neza, bigatuma intera iri hagati y'urwego rwo hejuru n'urwo hasi igaragara. Mu gihe cyo gusohora, ibi bitera itandukaniro rikomeye mu bunini bw'icyuma hagati y'urwego rwo hejuru n'urwo hasi rw'urwego rw'icyuma. Uduce tw'icyuma duto ku nkengero z'urupapuro rw'icyuma rwo hanze tubona stress nyinshi kandi ni two duce tw'ibanze aho hazaza hacikamo uduce.
Kugira ngo bigabanye ingaruka za kaseti y'icyuma ifite icyuma gikingira ku gipfundikizo cy'inyuma, urwego rwo gufunga rufite ubunini runaka rurapfundikirwa cyangwa rusohorwa hagati ya kaseti y'icyuma n'agapfundikizo ka PE. Uru rwego rwo gufunga rugomba kuba rufite ubunini bumwe, nta minkanyari cyangwa uduce duto. Kongeramo urwego rwo gufunga byongera uburyohe hagati y'ibice bibiri bya kaseti y'icyuma, bigatuma ubunini bwa kaseti ya PE bungana, kandi, hamwe no gufungana kw'agapfundikizo ka PE, bigabanya umuvuduko w'imbere.
ONEWORLD itanga ubunini butandukanye bw'ibicuruzwa ku bakoreshaibikoresho by'icyuma bya galvanised tepiguhaza ibyifuzo bitandukanye.
2.2 Ingaruka z'Ibikorwa byo Gukora Insinga
Ibibazo by'ingenzi mu nzira yo gusohora insinga nini zo hanze zifite umurambararo munini ni ugukonjesha kudahagije, gutegura nabi ibumba, no kunanura cyane, bigatera imbaraga nyinshi imbere mu gikapu. Insinga nini, bitewe n'insinga zazo nini kandi zagutse, zikunze guhura n'imbogamizi mu burebure n'ingano y'amazi ku mirongo ikora insinga. Gukonjesha kuva kuri dogere selisiyusi zirenga 200 mu gihe cyo gusohora kugeza ku bushyuhe bw'icyumba bitera imbogamizi. Gukonjesha kudahagije bituma insinga yoroshye hafi y'urwego rw'insinga, bigatera gushwanyagurika ku buso bw'insinga iyo insinga ipfundikiye, amaherezo bigatera kwangirika no kuvunika mu gihe insinga zipfundikiye bitewe n'imbaraga zo hanze. Byongeye kandi, gukonjesha kudahagije bigira uruhare mu kongera imbaraga zo mu imbere nyuma yo gupfunyika, byongera ibyago byo gupfunyika kw'insinga bitewe n'imbaraga zikomeye zo hanze. Kugira ngo habeho gukonjesha bihagije, kongera uburebure cyangwa ingano y'insinga z'amazi ni ngombwa. Kugabanya umuvuduko wo gusohora mu gihe ukomeza gushyira pulasitiki mu gikapu no guha igihe gihagije cyo gukonjesha mu gihe cyo gupfunyika ni ngombwa. Byongeye kandi, ukurikije polyethylene nka polymer ya crystalline, uburyo bwo gukonjesha bugabanya ubushyuhe, kuva kuri 70-75°C kugeza kuri 50-55°C, hanyuma ukagera ku bushyuhe bw'icyumba, bifasha kugabanya imihangayiko y'imbere mu gihe cyo gukonjesha.
2.3 Ingaruka z'umurambararo wa Coiling ku Coiling ya Cable
Mu gihe cyo gufunga insinga, abakora insinga bubahiriza amahame y’inganda yo guhitamo insinga zigomba gutangwa. Ariko, kwakira uburebure burebure bwo gutanga insinga nini zo hanze bitera imbogamizi mu guhitamo insinga zikwiye. Kugira ngo zuzuze uburebure bwagenwe bwo gutanga, bamwe mu bakora inganda bagabanya uburebure bw’insinga, bigatuma insinga idakora neza. Gupfundika cyane bituma insinga zigenda mu buryo butari bwiza, bigatera imbaraga nyinshi zo gukata insinga. Mu bihe bikomeye, uduce tw’icyuma gikingira insinga dushobora gutobora urwego rwo gupfunyika, rugashyirwa mu gipfunyika bigatera imiturire cyangwa imyanya ku nkengero z’insinga. Mu gihe cyo gushyiraho insinga, imbaraga zo gupfundika no gukurura zituma igipfunyika gicika kuri izi myenge, cyane cyane ku nsinga zegereye urwego rw’imbere rw’insinga, bigatuma zishobora kwangirika cyane.
2.4 Ingaruka z'ibidukikije byo kubaka no gushyiraho aho hantu
Kugira ngo insinga zishyirweho mu buryo busanzwe, ni byiza kugabanya umuvuduko wo gushyira insinga, kwirinda igitutu kinini cyo ku ruhande, kunama, imbaraga zikurura, no kugongana n'ubuso, bigatuma imiterere y'ubwubatsi iba myiza. Byaba byiza mbere yo gushyiraho insinga, reka insinga iruhuke kuri 50-60°C kugira ngo ikuremo imbaraga zo mu gikoni. Irinde ko insinga zihagarara igihe kirekire ku zuba ryinshi, kuko ubushyuhe butandukanye ku mpande zitandukanye z'insinga bushobora gutuma insinga zigwa, bikongera ibyago byo gucika kw'igikoni mu gihe cyo gushyiraho insinga.
