Umusenyi canke umusenyi w’umusenyi wo ku ruhande rw’umusenyi ushizweko igice c’ibara ry’umubiri rikomeye imbere y’uko ubumbabumba. Hariho uburyo bubiri bwo gupfuka: uburyo bukonje n’uburyo bushushe. Mu buryo bw’ubukonje, resine irasenyuka na ethanol na urethane irashirwa mu gihe c’uguvanga umusenyi kugira ngo ishire ku ruhande rw’intete z’umusenyi. Ico gikoresho citwa ethanol kirahinduka umwuka kugira ngo kironke umusenyi upfutse. Uburyo bw’ubushuhe bujanye n’ugushushanya umusenyi ku bushuhe bumwe, bwongerako resine kugira ngo ugifungure, gutera imbere kugira ngo upfuke uburebure bw’intete z’umusenyi n’ibara ry’umusenyi, kwongera umuti w’amazi ya rotropine n’amavuta, gukonjesha, gukama no gusesa umusenyi upfutse. Ikoreshwa ku bihimba vy'icuma n'ibice vy'icuma
Ibintu Insobanuro
Ivyiza vy'umusenyi
1. Ugushikama kw’imbere: Ivyokurya bikozwe mu musenyi upfutse biragaragaza neza neza neza be n’uburyo bwiza bwo ku ruhande, kandi ntibikunda guhungabana.
2. Ugushikama neza kw’ubushuhe: Umusenyi w’umusenyi urashobora guhangana n’ubushuhe bwinshi ata guhinduka kw’ubushuhe canke ugusaduka, kandi ubunini n’imiterere y’ibikoresho vy’ivyuma na vyo nyene birashobora kuguma bikomeye.
3. Ugukomera gukomeye: Umusenyi upfutse udasanzwe urafise ugushikama kw’ubushuhe bwinshi cane n’inkomezi z’ugukomera, kandi urashobora gusubira gukoreshwa incuro nyinshi, bikagabanya cane amafaranga y’uguhingura.
4. Urutonde rw’ikoreshwa ry’ivyuma: Umusenyi w’umusenyi urabereye gutera ivyuma nk’ivyuma, ivyuma, umuringa n’ivyuma vy’aluminium, hamwe n’ibitari - ivyuma nk’ivy’ivyuma n’ibirahuri, kandi birafise ubushobozi bwo guhindura cane.
Ivyago vy'umusenyi
1. Igiciro kinini co guhingura: Guhingura umusenyi upfutse bisaba gukoresha imiti idasanzwe kugira ngo umuntu avure, ivyo bikaba bituma habaho amahera menshi cane yo gukora.
2. Ubumara bwinshi: Ivyo bikoresho bikoreshwa mu guhingura umusenyi upfutse, nk’ivyo bita phenolic resine na polyurethane, birafise ubumara bumwebumwe ku bidukikije no ku buzima bw’umuntu.
3. Ubushobozi bwo guhingura ibiharuro binini binini vy’abantu: Kubera imiterere y’umubiri w’umusenyi upfutse, amapantalo asohoka ni make cane kandi ntashobora gushitsa ibisabwa vyo gukora ibikoresho bininibinini.
Ivyiyumviro vy'Ivyiyumviro
Ivyo gukora ibikoresho bisaba ko umuntu agira ubwiza bwinshi kandi akagira uburyo bwiza bwo ku ruhande.
2. Gukora ibikoresho vy’ivyuma bisaba ko ubushuhe bugumaho cane, nk’ubwo bujanye n’ubushuhe bwinshi canke imikazo myinshi.
3. Imisa - Gutanga ibiharuro bitobito.
High- Umusenyi w’umusenyi ushobora guhangana n’ishirahamwe ryacu ryizigirwa cane n’abaguzi .
