Chlorine Polyethylene (cpe) ni iki kandi ikoreshwa he?
Argonated polyethylene cpe yubucucike buke bwa polyethylene 2 silicone reberi ivanga insinga yibikoresho ni insimburangingo nke ya polyethylene (LDPE) na polydimethylsiloxane ihujwe na Ethyl methacrylate (EMA) (PDMS) ivangwa rya reberi ni ibikoresho byiza birinda ubushyuhe.Ibikoresho bitandukanye byamashanyarazi, imiterere yubukanishi nubushyuhe bwumuriro wavanze byizwe.Ibisubizo byerekana ko imvange ishobora gukoreshwa nkibikoresho bya Thermal insulation, ugereranije nibikoresho bya silicone, bifite imikorere myiza.
Kuva kera, abantu babonaga reberi ya silicone nka reberi idasanzwe yinsinga muburyo butandukanye bwubushyuhe bwo hejuru kandi buke.Ariko, igiciro gihenze cya silicone reberi igabanya aho ikoreshwa.
LDPE ni plastike ifite umubare munini mu nganda.Ifite igiciro gito kandi gifite ibikoresho byiza byamashanyarazi, kuburyo ikoreshwa cyane nka polymer insuline mu nsinga ziciriritse na voltage ntoya hamwe ninsinga.LDPE ntabwo iri hasi yikiguzi gusa ariko nanone ugereranije ni mike ya dielectric ihoraho nigihombo, irwanya imbaraga nyinshi, hamwe nubukanishi buhebuje buri munsi yubushyuhe bwibidukikije bwa 90C, bityo reberi nyinshi ya sintetike, nka reberi ya styrene-butadiene (SBR), butyl rubber (IR) ), neoprene (CR) nibindi byatakaje igice cyumugabane wisoko.Ugereranije nibikoresho bya silicone reberi, kuvanga polydimethylsiloxane (PDMS) na LDPE bifite inyungu zo kugiciro gito kugirango byuzuze amanota atandukanye, Usibye ibisabwa byihariye byinsinga zo gukwirakwiza amashanyarazi, kugenzura nibikoresho, abantu bakomeje gutera imbere ibikoresho bitandukanye bishya bya polymer.Nyamara, imiterere yubukanishi hamwe nubushyuhe bwumuriro wamashanyarazi make (<10kV) ibikoresho birarenze
Ibikoresho byamashanyarazi nibyingenzi.
Kurugero;umugozi wokoresha insinga zigomba kugira ituze ryimiterere yubukonje bwinshi.Mu buryo nk'ubwo;ibisabwa kugirango umwotsi muke, urwanya amavuta, hamwe ninsinga zidakira nazo ziratandukanye.Umugozi rero ugomba Gusaba umwanya ugena ibisabwa kubikorwa byihariye bya kabili.Kwangirika kwa okiside ya reberi no gukora urwego rwa oxyde hejuru bizongera ubworoherane, kubera ko iyo reberi imaze kuba okiside, habaho polarite hagati ya karubone yumukara.
Amatsinda (nka carboxyl) Aya matsinda atanga inzira ngufi ya electron.Hariho ibintu byinshi ugomba gusuzuma muguhitamo ibikoresho byo gusaba.Kubyerekeranye no kubika insinga;ikintu cyingenzi ni Imipaka yubushobozi bwubu bwo kunyura murwego rwo kubika.Kuburyo butaziguye (dc), biragaragara ko gukoresha ibikoresho birwanya imbaraga nyinshi bishobora kugabanya ubunini bwurwego rwimikorere;kubihinduranya bigezweho (ac), ugereranije uruhushya no gutakaza ni bike.
Ikintu cyo gutandukana nacyo kigabanya ubukana bwa insulation.
Ethyl methacrylate (EMA) irashobora gusimburwa ahanini na reberi ya silicone nkibikoresho byokwirinda hakoreshejwe imiti ya PDMS kubintu bitandukanye byamashanyarazi, imiterere yubukanishi no kurwanya ubushyuhe.
Imikorere yingero zingana nkihuza LDPE na PDMSA ivanze (50:50).
1. Sisitemu yo kurinda umutekano, CPE izarekura hydrogène chloride mugihe yashyutswe cyangwa ikirunga, bityo stabilisateur zifite ingaruka zo kwinjiza aside zigomba gukoreshwa muri formula, nka calcium stearate, barium stearate, tribasic lead sulfate cyangwa oxyde ya magnesium.
Sisitemu ya plastike.Amashanyarazi ya Ester akoreshwa cyane muri CPEZ, nka dioctyl phthalate (DOP) na dioctyl adipate (DOA).Ibipimo byabo byo gukemura biri hafi ya CM.Ubushobozi bwiza.Gukoresha DOA na DOS muri reberi birashobora guha reberi kwihanganira ubukonje buhebuje.
3. Sisitemu yo kurunga ya CPE, CPE ni reberi yuzuye, kandi sisitemu isanzwe ya sulfuru ntishobora kurigata neza.Ikoreshwa rya mbere rya sisitemu ya volcanisation ya sisitemu ni sisitemu ya thiourea, ingirakamaro muri zo ni Na-22, ariko Na-22 ifite umuvuduko ukabije w’ibirunga, imikorere idahwitse yo gusaza, gushyiramo compression nyinshi, na Na-22 ni kanseri ikomeye.Bitanga impumuro idashimishije, kandi imikoreshereze yabujijwe mu mahanga.
4. Gushimangira sisitemu yo kuzuza, CPE ni ubwoko bwa reberi yo kutiyubaka, bisaba sisitemu yo gushimangira kugirango igere ku mbaraga nziza.Sisitemu yo gushimangira yuzuza sisitemu isa niy'ibisanzwe-intego ifatika.Umukozi ushimangira cyane cyane karubone umukara na karubone yera.Umukara wa karubone yera urashobora kunoza amarira ya CPE, kandi urashobora gukora sisitemu yera ya metamethyl kugirango utezimbere hagati ya CPE na skeleton.komatanya.CPE ifite ibintu byinshi byuzuye, kandi sisitemu yo kuzuza irimo karubone ya calcium, ifu ya talcum, ibumba, nibindi.
