Mu gihe ibisabwa mu kwirinda inkongi bikomeje kwiyongera muri sisitemu zo gutwara abantu muri gari ya moshi, mu bigo bitanga amakuru, mu nyubako ndende, mu bitaro no mu mishinga y’ingufu zisubiramo, insinga za Low Smoke Zero Halogen (LSZH) zirimo kuba amahitamo meza ku bikorwa byinshi by’ingenzi. Ku bakora insinga, LSZH si icyiciro cy’ibicuruzwa gusa—igaragaza inzira y’ikoranabuhanga itandukanye cyane ugereranyije n’ibikoresho bisanzwe bya PVC.
Ibikoresho bya LSZH ni iki?
LSZH (Halogen y'umwotsi muke nta ruhu), izwi kandi nka Low Smoke Halogen Free (LSHF), yerekeza ku bwoko bw'ibikoresho bigabanya umuriro bidahumanya ibidukikije bikoreshwa mu gukingira insinga no kuziba. Mu nganda z'insinga, ibi bikoresho bikunze gushyirwa mu byiciro bya HFFR (Halogen Free Flame Retardant).
Ibinyabutabire bya LSZH ubusanzwe bishingiye kuri resins za polyolefin nka polyethylene (PE) na ethylene-vinyl acetate (EVA). Bikozwe mu bikoresho bigabanya umuriro bidafite halogen, harimo aluminiyumu hydroxide (ATH) na magnesium hydroxide (MDH), hamwe na antioxydants, amavuta, n'ibikoresho bifasha mu gutunganya. Bitandukanye n'ibinyabutabire bya PVC, ibikoresho bya LSZH ntibirimo chlorine, bromine, cyangwa ibindi bintu bya halogen.
Ugereranyije n'insinga zisanzwe za PVC, ibikoresho bya LSZH bishobora kubungabunga ubushyuhe bw'amashanyarazi n'imiterere ya mekanike mu gihe bigabanya cyane umwotsi n'imyuka yangiza mu gihe cyo gutwika. Kubera iyo mpamvu, bikoreshwa cyane mu gukoresha insinga aho umutekano w'inkongi ari ikintu cy'ingenzi cyane.
Ni irihe tandukaniro riri hagati ya LSZH na PVC?
Polyvinyl chloride (PVC) ikomeje kuba imwe mu nsinga zikoreshwa cyane bitewe n'ikoranabuhanga ryayo ryo gutunganya, uburyo ikoresha neza amafaranga, ndetse n'imikorere yayo muri rusange. Ikunze gukoreshwa mu kubaka insinga, insinga z'amashanyarazi, ndetse no mu nganda.
Ibikoresho bya LSZH, mu buryo butandukanye, bishingiye kuri sisitemu ya polyolefin kandi bigabanya ubushyuhe binyuze mu bintu bigabanya ubushyuhe mu buryo budashingiye ku bidukikije aho gukoresha inyongeramusaruro zirimo halogen. Itandukaniro rikomeye hagati y’ibyo byombi rigaragara mu gihe cy’inkongi.
PVC ishobora kurekura umwotsi mwinshi n'imyuka yangiza irimo chlorine iyo itwitswe. Ku rundi ruhande, ibikoresho bya LSZH bitanga umwotsi muke cyane kandi ntibisohora imyuka myinshi ya aside halogen. Ibi bifasha kugumana isura nziza mu gihe cyo kuva mu nzu kandi bigabanya kwangirika kw'ibikoresho by'amashanyarazi n'iby'ikoranabuhanga.
Byongeye kandi, ibikoresho bya LSZH bihuye neza n'ibisabwa mu mishinga igezweho y'ibikorwa remezo bigezweho mu mutekano no mu kubungabunga ibidukikije, harimo sisitemu zo gutwara abantu muri gari ya moshi, ibigo by'amakuru, ibibuga by'indege, ibitaro n'inyubako rusange. PVC iracyatanga ibyiza mu bijyanye n'ikiguzi no gutunganya neza, bigatuma ikoreshwa mu bikorwa byinshi bisanzwe.
Ukurikije uburyo ubushyuhe budashobora kwihanganirwa, imvange za LSZH zishobora gukorwa kugira ngo zihuze n'ubushyuhe bwa 70°C, 90°C, 105°C, ndetse no hejuru, bitewe n'ibisabwa gukoreshwa. Imvange gakondo za PVC zikoreshwa mu bikoresho by'insinga bifite agaciro ka 70°C cyangwa 90°C. Kubera iyo mpamvu, ibikoresho bya LSZH birushaho gukundwa mu bikorwa bisaba umutekano mwinshi no gukora neza mu bushyuhe.
Ni ayahe mahame agomba kuba yujuje ibikoresho bya LSZH?
Ibikoresho nyabyo bya LSZH bigomba kubahiriza amahame yemewe n'inganda n'ibisabwa mu isuzuma.
Ku bijyanye n'imikorere idafite halogen, IEC 60754-1 na IEC 60754-2 bikunze kuvugwa mu gusuzuma ingano ya aside halogen isohoka mu gihe cyo gutwika, ndetse n'ubushyuhe n'ubushobozi bw'imyuka itwika. IEC 60754-2 ivuga ko agaciro ka pH k'imyuka itwika kagomba kuba munsi ya 4.3 kandi ubushobozi bw'amashanyarazi ntibugomba kurenga 10 μS/mm.
Ku bijyanye n'imikorere y'umwotsi muke, uruhererekane rwa IEC 61034 rupima ubucucike bw'umwotsi binyuze mu gupima kohereza urumuri.
Byongeye kandi, imikorere y’insinga zirinda umuriro ikunze gusuzumwa hakurikijwe amahame ya IEC 60332 na GB/T 18380, mu gihe GB/T 19666 igaragaza ibisabwa ku nsinga zirinda umuriro n’izidakira umuriro.
Ku masoko yohereza ibicuruzwa mu mahanga no mu mishinga mpuzamahanga, ibikoresho by'insinga nabyo bikunze gukenerwa kugira ngo hubahirizwe amabwiriza agenga ibidukikije nka RoHS na REACH.
Kuki imishinga myinshi ihitamo insinga za LSZH?
Gukomeza gukoresha insinga za LSZH biterwa no kwiyongera kw'ibikenewe mu kubungabunga umutekano w'inkongi, kurengera ibidukikije no kurengera imitungo.
Ibyiza by'ingenzi birimo:
Kugabanya umwotsi uturuka mu bihe by'inkongi z'umuriro, bigatuma habaho kugaragara neza kw'abantu bava mu rugo no gutabara mu gihe cy'impanuka.
Kugabanya irekurwa ry'imyuka ihumanya, bifasha mu kurinda sisitemu z'itumanaho, ibikorwa remezo by'amashanyarazi, ibikoresho byo mu kigo cy'amakuru, n'ibindi bikoresho by'ikoranabuhanga byoroshye.
Gukurikiza amabwiriza akaze yo kubungabunga ibidukikije n'ibipimo by'umushinga bikomeje kwiyongera.
Ikwiriye gukoreshwa mu bikorwa by’umutekano mwinshi nko gutwara abantu muri gari ya moshi, ibigo by’amakuru, ibibuga by’indege, ibitaro, sisitemu za photovoltaic, imodoka zikoresha amashanyarazi, n’ibigo binini bya leta.
Muri icyo gihe kandi, iterambere rihoraho mu ikoranabuhanga ry’ibikoresho ryazamuye cyane imiterere ya mekanike, imikorere y’ubushyuhe, imiterere yo gutunganya, ndetse n’uburyo bwo gukomeza kwizerwa kw’ibikoresho bigezweho bya LSZH bikingira n’ibikingira, birushaho kwagura uburyo bikoreshwa.
Ibisubizo by'ibikoresho bya ONE WORLD LSZH Cable
Nk'umwuga mu gukora ibikoresho by'insinga,ISI IMWEInzobere mu bushakashatsi, iterambere, umusaruro, n'ubufasha mu bya tekiniki ku bikoresho by'insinga. Ibicuruzwa byacu birimo LSZH Sheathing Compounds, LSZH Insulation Compounds, HFFR Compounds, Cross-Linked Polyolefin (XLPO) Compounds, na PVC Cable Compounds.
Ibi bikoresho bikoreshwa cyane mu nsinga z'amashanyarazi, insinga z'itumanaho, insinga za gari ya moshi, insinga zo mu kigo cy'amakuru, insinga za photovoltaic, insinga z'imodoka zikoresha amashanyarazi, n'izindi nsinga zidasanzwe.
Mu gukomeza kunoza imikorere y’ibikoresho no kubitunganya, ONE WORLD yiyemeje guha abakora insinga ibisubizo byizewe by’ibikoresho, ndetse n’ubufasha mu bya tekiniki bukubiyemo guhitamo ibikoresho, isuzuma ry’icyitegererezo, no gushyira mu bikorwa umusaruro mwinshi.
Umwanzuro
Uko ibisabwa mu mutekano bikomeje kwiyongera mu nzira za gari ya moshi, mu bigo bitanga amakuru, mu ngufu zishobora kuvugururwa, mu buryo bwo kubika ingufu, no mu mishinga y’ibikorwa remezo rusange, ibikoresho bya LSZH birimo kuba kimwe mu byerekezo by’ingenzi by’iterambere mu nganda zikora insinga.
Ugereranyije n'ibinyabutabire gakondo bya PVC, ibikoresho bya LSZH bitanga inyungu zikomeye mu bijyanye no kugabanya imyotsi ihumanya, imikorere ya halogen idafite, kubahiriza ibidukikije, no kurinda ibikoresho. Kubera iyo mpamvu, bigenda birushaho kuba amahitamo meza yo gukoresha insinga zitekanye cyane.
Bitewe n’uko amahame y’inganda agenda ahinduka ndetse n’izamuka ry’ubukene ku isoko, byitezwe ko ikoreshwa ry’ibikoresho bya LSZH rizakomeza kwaguka. ONE WORLD izakomeza kwiyemeza guteza imbere no gukora ibikoresho bya LSZH bifite imikorere myiza, itanga ibisubizo byizewe ku bikoresho ndetse n’ubufasha bw’umwuga mu bya tekiniki ku bakora insinga ku isi yose.
