Polyethylene yitwa Chlorinated Polyethylene (cpe) ni iki kandi ikoreshwa he?
Ibikoresho byo gukingira insinga bya polyethylene ya Argonated cpe polyethylene yo mu bwoko bwa 2 silicone rubber blend ni polyethylene yo mu bwoko bwa low density (LDPE) naho polydimethylsiloxane ihuzwa na ethyl methacrylate (EMA) (PDMS) rubber blend ni ibikoresho byo gukingira insinga birwanya ubushyuhe. Imiterere itandukanye y'amashanyarazi, imiterere ya mekanike n'imiterere y'ubushyuhe bw'uruvange byizweho. Ibisubizo bigaragaza ko uruvange rushobora gukoreshwa nk'ibikoresho byo gukingira ubushyuhe, ugereranije n'ibikoresho bya silicone rubber, rufite igiciro cyiza.
Kuva kera, abantu bafataga silicone rubber nk'icyuma cyihariye gikoreshwa mu nsinga mu bushyuhe bwinshi butandukanye. Ariko, igiciro gihenze cya silicone rubber kigabanya urugero rw'ikoreshwa ryayo.
LDPE ni pulasitiki ifite ingano nini mu nganda. Ifite igiciro gito kandi ifite imiterere myiza y'amashanyarazi, bityo ikoreshwa cyane nk'umusemburo wa polymeri urinda ubushyuhe mu nsinga n'insinga zikoresha ingufu ziciriritse n'iziciriritse. LDPE ntabwo ihendutse gusa mu giciro ahubwo inafite ubushobozi buke bwo gutakaza ingufu zikomoka ku mashanyarazi, ifite ubushobozi bwo guhangana n'ihindagurika ry'amashanyarazi, ifite ubushobozi bwo guhangana n'ihindagurika ry'amashanyarazi, ifite ubushobozi bwo guhangana n'ihindagurika ry'amashanyarazi, kandi ifite imiterere myiza ya mashini iri munsi y'ubushyuhe bwa dogere selisiyusi 90, bityo imashini nyinshi za sintetike, nka styrene-butadiene rubber (SBR), butyl rubber (IR), neoprene (CR) n'izindi zatakaje igice cy'isoko. Ugereranyije n'ibikoresho bya silikoni bikingira rubber, uruvange rwa polydimethylsiloxane (PDMS) na LDPE rufite akarusho ko ku giciro gito kugira ngo ruhuze n'imiterere itandukanye. Uretse ibisabwa byihariye by'insinga zo kohereza ingufu, kugenzura n'ibikoresho, abantu bakomeje gukora ibikoresho bishya bikingira amashanyarazi bya polymeri. Ariko, imiterere ya mashinii n'ubushyuhe bw'ibikoresho by'amashanyarazi bifite ingufu nke (<10kV) biri hejuru kurusha
Imiterere y'amashanyarazi ni ingenzi cyane.
Urugero; urwego rwo gukingira insinga z'itanura rugomba kugira ubushobozi bwo kugumana neza n'imikorere ya mekanike ku bushyuhe bwinshi. Mu buryo nk'ubwo; ibisabwa ku nsinga zidakoresha umwotsi mwinshi, zidakoresha amavuta, kandi zidakoresha umuriro nabyo biratandukanye. Bityo, insinga igomba gukoreshwa. Igihe cyo kuyikoresha kigena ibisabwa kugira ngo insinga ikore neza. Kwangirika kwa ogisijeni kw'urukuta no kurema urwego rwa ogisijeni ku buso byongera ubushobozi bwo gutwara, kuko nyuma y'uko rukuta rukozwe ogisijeni, polarity iravuka hagati y'ibice by'umukara wa karuboni.
Amatsinda (nka carboxyl) Aya matsinda atanga inzira ngufi ya electron. Hari ibintu byinshi byo kuzirikana mu gihe cyo guhitamo ibikoresho byo gukoresha. Ku bijyanye no gukingira insinga; ikintu cy'ingenzi ni uko bigabanya ubushobozi bw'amashanyarazi bwo kunyura mu gice cyo gukingira insinga. Ku muyoboro w'amashanyarazi utaziguye (dc), biragaragara ko gukoresha ibikoresho birwanya cyane bishobora kugabanya ubunini bw'igice cyo gukingira insinga; ku muyoboro w'amashanyarazi usimburana (ac), uburenganzira n'igihombo biri hasi cyane.
Ikintu cyo gukwirakwiza ibintu kigabanya ubugari bw'ubushyuhe.
Ethyl methacrylate (EMA) ishobora gusimburwa ahanini na silicone rubber nk'ibikoresho byo kwishyushya hakoreshejwe PDMS blends ku miterere itandukanye y'amashanyarazi, imiterere ya mekanike ndetse no kwirinda ubushyuhe.
Ingufu z'ingano imwe n'iy'umuti uhuza LDPE na PDMSA (50:50).
1. Sisitemu yo kurinda ihamye, CPE izarekura hydrogen chloride iyo ishyushye cyangwa ivungaguritse, bityo hagomba gukoreshwa ibintu bikomeza umwuka bifite ingaruka zo kwinjiza aside muri iyo formula, nka calcium stearate, barium stearate, tribasic lead sulfate cyangwa magnesium oxide.
2. Sisitemu yo gushushanya pulasitiki. Imashini zikoresha pulasitiki za ester zikunze gukoreshwa muri CPEZ, nka dioctyl phthalate (DOP) na dioctyl adipate (DOA). Ibipimo byazo byo gushonga biri hafi y’ibya CM. Ubushobozi bwiza. Gukoresha DOA na DOS muri rubber bishobora gutuma rubber ihangana neza n’ubukonje.
3. Sisitemu yo gukurura CPE, CPE ni umukara wuzuye, kandi sisitemu isanzwe yo gukurura sulfur ntishobora kuyikurura neza. Uburyo bwa mbere bwo gukoresha sisitemu yo gukurura CPE ni sisitemu ya thiourea, ifite akamaro kanini muri yo ni Na-22, ariko Na-22 ifite umuvuduko muto wo gukurura, idakora neza mu gusaza, ifite ubushobozi bwo gukanda cyane, kandi Na-22 ni kanseri ikomeye. Itanga impumuro mbi, kandi ikoreshwa ryayo ryaragabanijwe mu mahanga.
4. Sisitemu yo kongera imbaraga mu kuzuza, CPE ni ubwoko bwa rubber idakomeza imbaraga, isaba sisitemu yo kongera imbaraga kugira ngo igere ku mbaraga nziza. Sisitemu yayo yo kongera imbaraga isa n'iya kole ikoreshwa muri rusange. Ingufu zo kongera imbaraga ahanini ni umukara wa karuboni n'umukara wa karuboni wera. Umukara wa karuboni wera ushobora kongera ubushobozi bwo kurwanya amarira ya CPE, kandi ushobora gukora sisitemu yera ya metamethyl kugira ngo wongere uburyo bwo gufatana hagati ya CPE n'amagufwa. CPE ifite ubushobozi bwo kuzuza bwinshi, kandi sisitemu yo kuzuza irimo karuboni karuboni, ifu ya talcum, ibumba, nibindi.
