Polyethylene (PE) ikoreshwa cyane murikubika no gutema insinga z'amashanyarazi n'insinga z'itumanahokubera imbaraga zidasanzwe zubukanishi, ubukana, kurwanya ubushyuhe, kubika, no gutuza imiti. Ariko, kubera imiterere yimiterere ya PE ubwayo, irwanya ihungabana ry’ibidukikije ni rito. Iki kibazo kigaragara cyane mugihe PE ikoreshwa nkicyuma cyo hanze cyinsinga nini zintwaro.
1. Mechanism ya PE Sheath Cracking
PE kumenagura ibyatsi bibaho cyane mubintu bibiri:
a. Ibidukikije byangiza ibidukikije: Ibi bivuga ibintu aho urusenda ruvunika hejuru kubera guhangayika hamwe cyangwa guhura nibitangazamakuru bidukikije nyuma yo gushiraho insinga no gukora. Biterwa ahanini nihungabana ryimbere mumashanyarazi no kumara igihe kinini uhura namazi ya polar. Ubushakashatsi bwimbitse ku guhindura ibintu byakemuye cyane ubu bwoko bwo guturika.
b. Gukomeretsa Mechanical Stress: Ibi bibaho bitewe nuburyo bubi bwubatswe mumigozi cyangwa uburyo bwo gukuramo ibyatsi bidakwiye, biganisha ku guhangayikishwa cyane no guterwa no guhindagurika biterwa no gushiraho insinga. Ubu bwoko bwo guturika bugaragara cyane mumashanyarazi yinyuma yibice binini byuma bya kaseti.
2. Impamvu zitera PE Sheath Kumena no Gutezimbere
2.1 Ingaruka z'umugoziIcyumaImiterere
Mu nsinga zifite umubyimba munini wo hanze, urwego rwintwaro rugizwe nibice bibiri bya kaseti. Ukurikije diameter yo hanze ya kabili, uburebure bwa kaseti y'icyuma buratandukanye (0.2mm, 0.5mm, na 0.8mm). Ibyuma bifata ibyuma bifata ibyuma bifite ubukana bwinshi kandi bidafite plastike, bigatuma habaho intera nini hagati yo hejuru no hepfo. Mugihe cyo gukuramo, ibi bitera itandukaniro rikomeye mubyimbye hagati yicyiciro cyo hejuru no hepfo yubuso bwintwaro. Ahantu hakeye cyane kumpera yicyuma cyo hanze hashobora kwibandwaho cyane kandi niho hantu hambere hazavunika.
Kugirango ugabanye ingaruka za kaseti yicyuma ku cyuma cyo hanze, igipande cyerekana umubyimba runaka cyiziritse cyangwa gisohorwa hagati yicyuma nicyuma cya PE. Uru rupapuro rugomba kuba rwuzuye, rutagira iminkanyari. Kwiyongera kumurongo wa bffer bitezimbere ubworoherane hagati yibyiciro byombi bya kaseti, bigatanga umubyimba umwe wa PE, kandi, hamwe no kugabanuka kwicyatsi cya PE, bigabanya imihangayiko yimbere.
ONEWORLD itanga abakoresha nubunini butandukanye bwaibyuma bya galvanised kaseti ibikoresho byintwaroguhaza ibikenewe bitandukanye.
2.2 Ingaruka zuburyo bwo gutunganya insinga
Ibibazo byibanze hamwe nogusohora inzira nini ya diametre yo hanze ya kaburimbo ya kabili ni gukonjesha bidahagije, gutegura ibishushanyo bidakwiye, hamwe no kurambura gukabije, bikaviramo guhangayika cyane imbere muri sheath. Intsinga nini nini, bitewe nubushyuhe bwazo nubugari, akenshi zihura nimbogamizi muburebure nubunini bwamazi yamazi kumurongo utanga umusaruro. Gukonja kuva kuri dogere selisiyusi 200 mugihe cyoherejwe mubushyuhe bwicyumba bitera ibibazo. Gukonjesha bidahagije biganisha ku cyatsi cyoroshye hafi yintwaro, bigatera gushushanya hejuru yuruhu iyo umugozi umaze gutwikwa, amaherezo bikaviramo kuvunika no gucika mugihe cyo gushyiramo insinga bitewe nimbaraga zo hanze. Byongeye kandi, gukonja bidahagije bigira uruhare mu kongera imbaraga zo kugabanuka imbere nyuma yo gukonjesha, bikazamura ibyago byo guturika ibyatsi munsi yimbaraga nyinshi zo hanze. Kugirango habeho gukonja bihagije, kongera uburebure cyangwa ingano yimigezi y'amazi birasabwa. Kugabanya umuvuduko wo gusohora mugihe ukomeje plastike ikwiye kandi ukemerera umwanya uhagije wo gukonjesha mugihe cyo guteka ni ngombwa. Byongeye kandi, urebye polyethylene nka polymer ya kristalline, uburyo bwo kugabanya ubushyuhe bwo kugabanya ubukonje, kuva kuri 70-75 ° C kugeza kuri 50-55 ° C, hanyuma kugeza mubushyuhe bwicyumba, bifasha kugabanya imihangayiko yimbere mugihe cyo gukonja.
2.3 Ingaruka za Coiling Radius kuri Cable Coiling
Mugihe cyo guhuza insinga, abayikora bakurikiza amahame yinganda kugirango bahitemo ibicuruzwa bikwiye. Ariko, kwakira uburebure burebure bwo gutanga insinga nini ya diameter yo hanze bitera ibibazo muguhitamo ibyuma bikwiye. Kugirango wuzuze uburebure bwatanzwe, ababikora bamwe bagabanya diameter ya reel barrel, bikavamo radii idahagije ya kabili. Kwunama cyane biganisha ku kwimuka mu ntwaro, bigatera imbaraga zikomeye zo kogosha. Mu bihe bikomeye, ibyuma byitwaje ibirwanisho byintwaro birashobora gutobora igipande cyo kuryamaho, kikinjira mu cyatsi kandi bigatera ibice cyangwa ibice ku nkombe z'icyuma. Mugihe cyo gushyiramo insinga, imbaraga zunamye no gukurura zitera igishishwa kumeneka kuri ibyo bice, cyane cyane kubitsinga byegereye ibice byimbere bya reel, bigatuma bikunda kumeneka.
2.4 Ingaruka zo Kwubaka no Kwubaka Ibidukikije
Kugirango uburinganire bwubatswe busanzwe, birasabwa kugabanya umuvuduko wo gushyira insinga, kwirinda umuvuduko ukabije wuruhande, kunama, gukurura imbaraga, no kugongana hejuru, bigatuma ibidukikije byubaka. Byaba byiza, mbere yo kwishyiriraho umugozi, emera umugozi kuruhuka kuri 50-60 ° C kugirango urekure impungenge zimbere mumashanyarazi. Irinde kumara igihe kinini insinga zerekeza kumurasire yizuba, kuko ubushyuhe butandukanye kumpande zinyuranye z'umugozi bushobora gutuma uhangayikishwa cyane, bikongera ibyago byo gucika ibyatsi mugihe cyo gushyira insinga.
