(1)Kwambukiranya Umwotsi muke Zeru Halogen Polyethylene (XLPE) Ibikoresho byo kubika:
Ibikoresho bya XLPE bikozwe no guhuza polyethylene (PE) na Ethylene vinyl acetate (EVA) nka matrix fatizo, hamwe ninyongeramusaruro zitandukanye nka halogen idafite flame retardants, lubricants, antioxydants, nibindi, binyuze muburyo bwo guhuza no gutondagura. Nyuma yo gutunganya imirasire, PE ihinduka kuva kumurongo wa molekulari kumurongo igahinduka imiterere-yimiterere itatu, igahinduka kuva mubintu bya termoplastique igahinduka plastike ya termosetting idashonga.
Intsinga ya XLPE ifite ibyiza byinshi ugereranije na termoplastique PE isanzwe:
1.
2. Kongera imbaraga za chimique no kurwanya ibishishwa, kugabanya ubukonje, no gukomeza amashanyarazi. Ubushyuhe bumaze igihe kirekire bushobora kugera kuri 125 ° C kugeza kuri 150 ° C. Nyuma yo guhuza gutunganya, ubushyuhe bwumuzunguruko bugufi bwa PE burashobora kwiyongera kugera kuri 250 ° C, bigatuma ubushobozi bwo gutwara ibintu hejuru cyane bwinsinga zububiko bumwe.
3 , insinga za metero, insinga zangiza ibidukikije zangiza ibidukikije, insinga zubwato, insinga zo mu rwego rwa 1E zinganda zikoresha ingufu za kirimbuzi, insinga za pompe zirohama, ninsinga zohereza amashanyarazi.
Icyerekezo kigezweho mugutezimbere ibikoresho bya XLPE harimo imirasire ihuza imiyoboro ya PE yamashanyarazi, ibikoresho bya irrasiyo ihuza ibikoresho byo mu kirere, hamwe na irrasiyo ihuza flame-retardant polyolefin yo gukata ibikoresho.
(2)Ibikoresho bihuza Polypropilene (XL-PP) Ibikoresho byo kubika:
Polypropilene (PP), nka plastiki isanzwe, ifite ibiranga nkuburemere bworoshye, amasoko menshi yibikoresho fatizo, gukoresha neza ibiciro, kurwanya imiti yangiza imiti, koroshya kubumba, no kongera gukoreshwa. Nyamara, ifite aho igarukira nkimbaraga nke, kutarwanya ubushyuhe bukabije, kugabanuka gukabije kugabanuka, kutagira umuvuduko muke, ubukonje buke, hamwe no kurwanya ubushyuhe no gusaza kwa ogisijeni. Izi mbogamizi zagabanije gukoresha imikoreshereze ya kabili. Abashakashatsi bagiye bakora kugirango bahindure ibikoresho bya polypropilene kugirango barusheho kunoza imikorere yabo, kandi imirasire ihuza imiyoboro ya polypropilene (XL-PP) yatsinze neza izo mbogamizi.
XL-PP insinga zishobora kuba zujuje ibizamini bya flame ya UL VW-1 hamwe na UL igipimo cya 150 ° C. Mubikorwa bya kabili bifatika, EVA ikunze kuvangwa na PE, PVC, PP, nibindi bikoresho kugirango uhindure imikorere yumurongo wa insulasiyo.
Imwe mu mbogamizi ziterwa na irrasiyo ihuza PP ni uko ikubiyemo imyitwarire irushanwa hagati yo gushinga amatsinda yanyuma atuzuye binyuze mubitekerezo byo gutesha agaciro no guhuza imiyoboro hagati ya molekile ikangurwa na molekile nini yubusa. Ubushakashatsi bwerekanye ko igipimo cyo guteshwa agaciro no guhuza ibikorwa muri PP irrasiyoya ihuza PP igera kuri 0.8 mugihe ukoresheje imishwarara ya gamma-ray. Kugirango ugere ku buryo bunoze bwo guhuza ibikorwa muri PP, guhuza porotokoro bigomba kongerwaho kugirango irrasiyo ihuza. Ikigeretse kuri ibyo, ubunini bwambukiranya imipaka bugarukira kubushobozi bwo kwinjira mumashanyarazi ya electron mugihe cyo kurasa. Irrasiyo iganisha ku kubyara gaze no kubira ifuro, ibyo bikaba byiza mu guhuza ibicuruzwa bito ariko bikagabanya ikoreshwa ry'insinga zifite urukuta runini.
.
Mugihe ibyifuzo byumutekano wa kabili byiyongera, iterambere ryumuriro wa halogen-flame-retardant ihuza imiyoboro yateye imbere byihuse. Ugereranije na PE, EVA, itangiza vinyl acetate monomers mumurongo wa molekile, ifite kristu yo hasi, bigatuma habaho guhinduka neza, kurwanya ingaruka, guhuza kuzuza, hamwe nubushuhe bwo gufunga ubushyuhe. Mubisanzwe, imiterere ya EVA resin iterwa nibiri muri vinyl acetate monomers mumurongo wa molekile. Ibintu byinshi bya vinyl acetate biganisha ku gukorera mu mucyo, guhinduka, no gukomera. EVA resin ifite ubwuzuzanye bwiza kandi bwuzuzanya, bigatuma irushaho gukundwa muri halogen-idafite flame-retardant ihuza insinga.
EVA resin ifite vinyl acetate igera kuri 12% kugeza 24% ikoreshwa muburyo bwinsinga. Mubikorwa byukuri bya kabili, EVA ikunze kuvangwa na PE, PVC, PP, nibindi bikoresho kugirango uhindure imikorere yumurongo wa insulasiyo. Ibigize EVA birashobora guteza imbere guhuza, kunoza imikorere ya kabili nyuma yo guhuza.

XL-EPDM ni terpolymer igizwe na Ethylene, propylene, hamwe na monomers ya diene idahuza, ihujwe no kurasa. Umugozi wa XL-EPDM uhuza ibyiza byinsinga za polyolefin hamwe ninsinga zisanzwe zikoreshwa na reberi:
1. Guhinduka, kwihangana, kudafatana n'ubushyuhe bwo hejuru, kurwanya gusaza igihe kirekire, no kurwanya ikirere gikaze (-60 ° C kugeza 125 ° C).
2. Kurwanya Ozone, kurwanya UV, gukora amashanyarazi, no kurwanya ruswa.
3. Kurwanya amavuta hamwe nudusimba ugereranije nintego rusange ya chloroprene reberi. Irashobora kubyazwa umusaruro hakoreshejwe ibikoresho bisanzwe bitunganyirizwa hanze, bigatuma bidahenze.
Intsinga ya XL-EPDM ifite insimburangingo zitandukanye, zirimo ariko ntizigarukira gusa ku nsinga z'amashanyarazi zifite ingufu nkeya, insinga z'ubwato, insinga zo gutwika imodoka, insinga zo kugenzura imashini zikonjesha, gucukura insinga zigendanwa, ibikoresho byo gucukura, n'ibikoresho by'ubuvuzi.
Ingaruka nyamukuru z’insinga za XL-EPDM zirimo kutarwanya amarira mabi hamwe n’imiterere idahwitse hamwe no kwifata, bishobora kugira ingaruka ku gutunganya nyuma.
(5) Ibikoresho bya Silicone Rubber
Rubber ya silicone ifite imiterere ihindagurika kandi irwanya cyane ozone, isohoka rya corona, numuriro, bigatuma iba ibikoresho byiza byo gukwirakwiza amashanyarazi. Ikoreshwa ryibanze mubikorwa byamashanyarazi ni insinga ninsinga. Silicone reberi insinga ninsinga birakwiriye cyane cyane gukoreshwa mubushyuhe bwo hejuru kandi busaba ibidukikije, hamwe nigihe kirekire cyo kubaho ugereranije ninsinga zisanzwe. Porogaramu zisanzwe zirimo moteri yubushyuhe bwo hejuru, transformateur, generator, ibikoresho bya elegitoroniki n amashanyarazi, insinga zo gutwika mumodoka zitwara abantu, hamwe ninsinga zo kugenzura no kugenzura.
Kugeza ubu, insinga za silicone reberi zisanzwe zifitanye isano hifashishijwe umuvuduko wikirere hamwe numwuka ushushe cyangwa umwuka mwinshi. Hariho kandi ubushakashatsi burimo gukorwa muburyo bwo gukoresha imirasire ya elegitoronike yo guhuza reberi ya silicone, nubwo itaragaragara cyane mu nganda. Hamwe niterambere ryambere mubikorwa bya irrasiyoya ihuza ikoranabuhanga, itanga igiciro gito, cyiza, kandi cyangiza ibidukikije kubikoresho bya silicone reberi. Binyuze mumirasire ya elegitoronike cyangwa izindi nkomoko yimirasire, guhuza neza kwifashisha reberi ya silicone irashobora kugerwaho mugihe byemerera kugenzura ubujyakuzimu nintera yo guhuza kugirango byuzuze ibisabwa byihariye.
Niyo mpamvu, ikoreshwa rya tekinoroji ya irrasiyoya ihuza ibikoresho bya silicone reberi itanga amasezerano akomeye mu nganda n’insinga. Iri koranabuhanga riteganijwe kugabanya ibiciro by’umusaruro, kuzamura umusaruro, no kugira uruhare mu kugabanya ingaruka mbi ku bidukikije. Imbaraga zigihe kizaza nimbaraga ziterambere zirashobora kurushaho guteza imbere ikoreshwa rya tekinoroji ya irradasiyo ihuza ibikoresho bya silicone reberi, bigatuma ikoreshwa cyane mugukora ubushyuhe bwo hejuru, insinga zikora cyane ninsinga munganda zamashanyarazi. Ibi bizatanga ibisubizo byizewe kandi biramba kubice bitandukanye byo gusaba.
