Umuyoboro w'ivyuma vy'ivyuma
Imiyoboro y'ivyuma vy'ivyuma, izwi kandi ko ari "umuyoboro w'amazi", ugizwe n'"uburyo bubiri bw'ivyuma", bugizwe n'umurongo w'inyuma w'ivyuma vy'ivyuma vy'ivyuma, ibikoresho vy'ivyuma vy'ivyuma vy'ivyuma vy'ivyuma vy'ivyuma vy'ivyuma vy'ivyuma vy'ivyuma vy'ivyuma vy'ivyuma vy'ivyuma vy'ivyuma vy'ivyuma vy'ivyuma vy'ivyuma vy'ivyuma. Ico gikoresho co gukingira ni igifu gikomeye gifise uburemere bwa 60 kg/m3 gushika kuri 80 kg/m3, ivyo bikaba vyongera neza ikinogo kiri hagati y’umuyoboro w’icuma n’igipfukisho, kandi gifise inkomezi zimwe zimwe zo gufatanya, ku buryo umuyoboro w’icuma, umuyoboro w’ijaketi n’ivyuma vy’ivyuma bikoresha ikintu gikomeye. Polyurethane ihamba ifu y’ubushuhe ifise ubushobozi bwiza bwo gukoresha ubushuhe n’ubushobozi bwo gukingira ubushuhe, akenshi ishobora guhangana n’ubushuhe bwinshi 120℃biciye mu guhindura canke gufatanya n’ibindi bikoresho vyo gukingira ubushuhe bishobora guhangana n’ubushuhe bwinshi 180 degre 180 , bibereye ku bwoko bwose bw’amazi akanye, ashushe n’ubushuhe buke bw’ubushuhe.
Polyurethane yahamba umuyoboro w'ubushuhe bw'ubushuhe burabereye ku bijanye n'ubuhinga bwo gukingira ubushuhe bw'ibinyamakuru bitandukanye biri ku rugero rwa 50℃- -150℃. Ikoreshwa cane mu gushushanya mu bisagara, ivyumba vy’ugushusha, ububiko bukonje, amakara, icuma c’amavuta, inganda y’imiti, umuyoboro wa gaze kavukire, umuyagankuba uhamba, umuyoboro wo hagati wo gukingira umuyaga, umuyoboro w’amazi, umuyoboro w’amazi n’izindi nganda z’ubuhinga bwo gukingira ubushuhe n’ubuhinga bwo gukingira imbeho.
Ivyiza vya polyurethane vyahambwe ata guca ku ruhande umurongo w’ubushuhe
1. Kugabanya igiciro c’umugambi. Dushingiye ku kubara inzego zijanye n’ivyo, umuyoboro w’ugushushanya kabiri, mu bihe bisanzwe, ushobora kugabanya igiciro c’umugambi c’ibice 25%, gukoresha FRP nk’igice c’uburinzi.
2. Ubushuhe buke n’ugukiza inguvu. Ubushobozi bwayo ni: λ=0.013—0.03kcal/
mhoC iri hasi cane y’ibindi bikoresho bikoreshwa cane mu gukingira imiyoboro mu bihe vya kera, kandi ingaruka z’ivyo bikoresho ni 4~9 incuro 4~9. Ikindi kandi, igitigiri c’amazi yayo y’amazi kiri hasi cane, ku bilo 0,2/m2. Impamvu y’ugunywa amazi make ni uko igitigiri c’ifu ya polyurethane kigera kuri nk’ibice 92%. Ubushobozi bwo gutwara ubushuhe n’amazi make, bifatanijwe n’igice c’ivyuma n’ubushobozi bwiza bwo gukingira amazi bw’ivyuma vy’uburemere bwinshi canke FRP, vyahinduye ivy’ugushushanya ivy’ugushushanya “impuzu y’impuzu y’impuzu y’impuzu”, bigabanya cane ubushuhe bwose bwo gushusha amazi, ubushuhe bw’uruzitiro rw’ubushuhe ni 2%, ni ukuvuga ko 10%.
3. Anti{{1}=Ubushobozi bwo gushakashaka, ubushobozi bwiza bwo gukingira, n’ubuzima buramba. Kubera ko igipande c’ivyuma vy’ivyuma bikomeye gifatanye n’urukoba rw’umuyoboro w’icuma, ukwatandukanywa n’ukwinjira kw’umuyaga n’amazi, gishobora gukina ingaruka nziza yo kurwanya {{3} =} Muri ico gihe nyene, imyobo yayo y’ifu irafunze, kandi amazi ni make cane. Igipfunsi c’uburemere bwinshi, igihimba c’umubiri c’ibirahuri gifise ugusenyuka neza, ivyuma bikingira umubiri n’imiterere y’ubuhinga. Ku bw’ivyo, urukoba rw’inyuma rw’umuyoboro w’icuma rukora uragoye gusenywa n’umuyaga wo hanze n’amazi. Igihe cose amazi yo mu mutima y’umuyoboro afatwa neza, hakurikijwe amakuru y’amahanga, ubuzima bw’ibikorwa burashobora gushika ku myaka irenga 50, ni ukuvuga incuro 3~4 kuruta ugutera imbere kw’imigende n’ugutera imbere kw’imbere.
4. Uburebure bw’ubutaka, ubwubatsi bwihuta, n’uburyo bwiza bwo gukingira ibidukikije. Umuyoboro w’ubushuhe utagira akamaro ntukeneye kwubaka umugende munini, gusa kugira ngo umuntu ahambe umuyoboro w’ivyuma mu mpisho, ku buryo bigabanya cane akarere k’umugambi, bikagabanya kwimba kw’ibikorwa vyo kw’isi n’ibice birenga 50%, bigabanya igitigiri c’amabuye y’agaciro n’amabuye y’agaciro n’amabuye y’agaciro 90%. Muri ico gihe nyene, ugutunganya imiyoboro y’ivyuma n’ivyo ku -Inyuma y’urugendo, ni yo yonyene ishobora kugabanya igihe c’ubwubatsi n’ibice birenga 50%.
Imisoro ishushe: umuyoboro w’ivyuma vy’ivyuma vy’ivyuma, Ubushinwa icuma c’icuma c’icuma c’icuma c’icuma, abatanga ibikoresho, uruganda .
