Muri iki gihe cy’iterambere ry’inganda ku isi, hari impinduka ituje ariko ikomeye mu buhanga bw’ubuhanga. Ishami rishinzwe amasoko n’abahanga mu by’ubuhanga barimo kuva ku “giciro gito cyane” bakajya ku “burambe bw’umutungo.” Mu bidukikije nko mu nganda zitunganya imiti, ahantu hasukurwa umunyu, no mu mirima y’umuyaga yo mu nyanja, ubwiganze bwa gakondo bwa SS316 stainless steel cyangwa hot-dip galvanized steel burimo kugeragezwa n’ubundi buryo bugezweho:Agasanduku k'insinga ka FRP(Plasitiki Ikomeye ya Fiberglass). Iri hinduka ntiriterwa n'ibintu bishya, ahubwo riterwa no kubara ingaruka mbi kandi zikomeye hamwe n'ikiguzi kinini cyihishe gifitanye isano no kwangirika kw'ibikorwaremezo.
Umusoro utagaragara wa ruswa
Mu duce tw’inganda cyangwa mu nyubako zifite umwuka mwinshi w’aside, ibyuma bibasirwa buri gihe. Ndetse n’ibyuma bitagira umugese byinshi bihura n’icyuho cyangwa kwangirika kw’umuvuduko iyo bihuye na chloride. Iyo insinga z’icyuma zinaniwe, ikiguzi ntigikunze kugarukira ku giciro cy’icyuma; kibarwa mu madolari ibihumbi yatakaye mu gihe cy’isaha imwe y’ibura ry’amashanyarazi ritari ryateganijwe rikenewe mu gusana.
Aha niho agasanduku k'insinga ka fiberglass gahindura cyane ikigereranyo. Bitandukanye n'ibyuma, bishingira ku bitwikirizo byo hejuru cyangwa ibice bidakora bishobora gushwanyagurika cyangwa kwangirika, FRP ntabwo ikoreshwa mu buryo bwa shimi mu miterere yayo yose. Ikorwa binyuze mu nzira yo guhumeka—aho insinga z'ikirahure zikomeye cyane zikururwa mu bwogero bwa resin ya thermosetting (ubusanzwe ni Vinyl Ester yo mu rwego rwo hejuru)—agasanduku "karinda" ingaruka z'amashanyarazi zitera ingese. Ku muyobozi w'ikigo, ibi bisobanurwa nk'umutungo "wo gushyiraho no kwibagirwa" uguma mu buryo bwiza mu myaka 30 kugeza kuri 50 nta irangi na rimwe rirwanya kwangirika.
Koroshya imiterere y'umutekano
Mu buryo bw'amashanyarazi gusa, guhinduranya kuriAgasanduku k'insinga ka FRPbyoroshya cyane imiterere ya sisitemu. Amasahani y'icyuma ni ibyuma biyobora, bivuze ko bisaba urusobe rwitonze rw'imiyoboro yo gufunga, gufatanya, n'imiyoboro y'ibikoresho kugira ngo hirindwe ko habaho guhungabana cyangwa ibishashi mu gihe cy'ikosa ry'insinga. Buri gice kigomba gushyirwamo ikiraro, kandi buri gice kigomba kugeragezwa kugira ngo kimenyekane ko gikomeza.
FRP, mu miterere yayo, ni icyuma gikingira amashanyarazi gifite imikorere myiza. Uku kudatwara amashanyarazi mu buryo busanzwe byongera urwego rw'ingenzi rw' "umutekano udahindagurika" ku kibanza. Bikuraho ibyago by'impanuka z' "amashanyarazi yo gukoraho" kandi bikarinda ikwirakwira ry'amakosa yo ku butaka binyuze mu nyubako y'inkunga. Mu bidukikije biturika cyangwa mu dusanduku dufite ingufu nyinshi, iyi mbaraga za dielectric ni ikintu kirokora ubuzima. Byongeye kandi, kubera ko FRP idakoresha ingufu za rukuruzi, ntabwo ihura n'ubushyuhe bw'amashanyarazi bushobora kubaho mu dusanduku tw'icyuma dutwara imizigo ya AC ifite amperage nyinshi, bigatuma insinga zikora neza cyane.
"Inyongeramusaruro" y'ibicuruzwa ku ba rwiyemezamirimo
Ku kibanza cy'ubwubatsi gihuze, uburemere ni ikintu cy'ingenzi mu gihe cy'umushinga.Agasanduku k'insinga ka FRPIpima hafi 25% by'icyuma kingana nacyo. Ku ba rwiyemezamirimo, ubu buremere bworoheje bugabanya gukenera ibikoresho biremereye cyangwa cranes zabugenewe mu gihe cyo gushyiraho ahantu hanini. Abakozi babiri bashobora gutwara no gushyira ku murongo igihe kirekire cy'isahani ya FRP, iyo bitabaye ibyo ikaba yakenera icyuma gikozwe mu byuma.
Ahari inyungu idahabwa agaciro cyane ni uburyo bworoshye bwo guhindura aho hantu. Mu nganda zigezweho, aho imiyoboro isanzwe ikunze gutuma habaho impinduka ku munota wa nyuma ku nzira z'insinga, ubushobozi bwo gukata no gucukura isahani ni ingenzi. Gukata isahani y'icyuma bitanga ibishashi, bisaba "Uruhushya rwo gukora rushyushye" - inzira ifata umwanya mu biro kandi itwara igihe kinini mu mazutu na gaze cyangwa imiti. Gukata isahani y'insinga ya fiberglass nta bishashi bitanga, bigatuma akazi gakomeza nta nkomyi. Iyo bihujwe n'amasahani ya modular splice hamwe n'ibikoresho byihuse bihuza, ubu buryo bwo kuzigama abakozi bukunze kugabanya igihe cyose cyo gushyiraho ho 15% kugeza kuri 20%.
Ubwubatsi bw'ibikoresho ku rwego rw'isi
Ni ngombwa kumenya ko amasahani yose agizwe n'ibice bitandukanye adashobora kungana. Sisitemu zifite ubuhanga buhanitse—nk'izakozwe na Qinkai—zikoresha imiti igabanya ubushyuhe bwa UV kugira ngo hirindwe “gukura kw'ibimera” (kwangirika kwa resin bitewe n'izuba). Mu bushyuhe bwinshi bwo mu Burasirazuba bwo Hagati cyangwa mu turere dufite imirasire myinshi ya UV mu gace ka Ositaraliya, izi nyongeramusaruro zituma isahani igumana imiterere yayo mu myaka ibarirwa muri za mirongo.
Byongeye kandi, uburyo bwo gukora ibintu bitandukanye muri resin matrix butuma habaho uburyo bwihariye bwo kudoda. Ahantu umutekano w'inkongi ariho hashyirwa imbere cyane, resin zirinda inkongi zishobora gukoreshwa kugira ngo zihuze n'ibipimo bikomeye bya ASTM E84 byo gukwirakwira k'umwotsi n'umuriro. Izi profili zirimo imvururu nazo zitanga imbaraga zitangaje; NEMA 20C ifite amanotaIngazi ya FRPishobora kwihanganira imitwaro minini y'insinga mu bugari bwa metero 6, bigabanyije umubare w'inkingi zihenze zikenewe mu kigo cyose.
Umwanzuro: Ikibazo cy'ubucuruzi ku mukino muremure
Iyo umuntu arebye gusa ku kintu cyatanzwe ku itegeko ryo gutanga ibicuruzwa, FRP ishobora kugaragara nk'ihenze kurusha icyuma cya galvanised. Ariko, iyo urebye mu ncamake ya "Ikiguzi cyose cy'Ubucuruzi" (TCO), inkuru irahinduka. Iyo uteranyije ikiguzi cyo kohereza kiri hasi (kubera uburemere), amasaha make y'akazi yo gushyiraho, gukuraho ibikoresho byo gusimbuza, ndetse - ikiruta byose - nta kintu na kimwe gisabwa mu kubungabunga mu gihe cy'imyaka 40, FRP ni yo mahitamo ahendutse cyane.
Uko ibikorwa remezo ku isi bigenda birushaho kugorana kandi ikiguzi cyo guhagarika ibikorwa gikomeza kwiyongera cyane,Agasanduku k'insinga ka FRPyavuye ku "bintu by'ingenzi" ijya ku "gipimo ngenderwaho." Ku batanga serivisi nka Sunnie, gutanga izi sisitemu ni ibirenze kugurisha; ni ugutanga ishingiro rihamye ry'umutungo w'inganda w'ingenzi cyane ku isi. Mu rugamba rwo kurwanya igihe n'ikirere, ahazaza h'inganda nta gushidikanya ko hazaba hari byinshi.
