TDore ibikoresho byinshi byo gukingira ubushyuhe bidukikije, hakurikijwe ikoreshwa ry’ibihe bitandukanye byo gushyira mu byiciro, nko mu buryo busanzwe harimo ibikoresho byo gukingira ubushyuhe ku gisenge cyangwa ibikoresho byo gukingira ubushyuhe ku nkuta, muri iki gihe byibanda ku gushyira mu byiciro ibikoresho byo gukingira inkongi ku nkuta zo hanze n’uburyo bwihariye bwo gushyira mu byiciro.
Bitewe n’iterambere ryihuse ry’ubwubatsi bugezweho, dufite ibisabwa byinshi ku mikorere y’urukuta rwo hanze. Tugomba kwiga no guhanga udushya ubuhanga bushya bwo gushyiramo ibikoresho bivanze bifite ingaruka nziza ku bushyuhe, imikorere myiza yo gutwika, kurengera ibidukikije, kandi igiciro gishobora kwemerwa na buri wese.
Amabwiriza yacu yo ku rwego rw'igihugu ya GB8624-97 agabanya imikorere y'ibikoresho by'ubwubatsi mu byiciro bikurikira:
1.Icyiciro: ibikoresho by'ubwubatsi bidashya: hafi ya byose nta bikoresho bishya bihari.
2.B1: Ibikoresho by'ubwubatsi bishya: Ibikoresho bishya bigira ingaruka nziza ku muriro. Biragoye gufata umuriro mu kirere iyo hari umuriro ufunguye cyangwa ubushyuhe bwinshi, ntabwo byoroshye gukwirakwira vuba, kandi iyo isoko ry'umuriro rikuweho, umuriro uzahita uhagarara.
3.Urwego rwa B2: ibikoresho by'ubwubatsi bishya: ibikoresho bishya bigira ingaruka zimwe na zimwe ku muriro. Mu kirere iyo hari umuriro ugurumana cyangwa ubushyuhe bwinshi, umuriro uhita utangira gukwirakwira, nk'inkingi z'ibiti, imbaho z'ibiti, imitako y'ibiti, ingazi z'ibiti, n'ibindi.
4.B3: ibikoresho by'ubwubatsi bishobora gushya: nta ngaruka zitinza umuriro, byoroshye gutwika, ingaruka zikomeye z'umuriro.
Ibikoresho byo gukingira inkuta byo hanze bigabanyijemo ibice hakurikijwe igipimo cy'umuriro:
1.Imikorere yo gutwika ku rwego rw'ibikoresho byo gukingira: ubwoya bw'amabuye, ubwoya bw'ibirahure, ikirahure cy'ifuro, ifuro rya ceramic, sima ya furo, perlite ifunze, nibindi.
2.Imikorere yo gutwika ibikoresho byo gukingira bya B1: nyuma yo gutunganya byihariye plaque ya polystyrene (XPS) / nyuma yo gutunganya byihariye polière (PU), phenolic, utuntu twa polystyrene y'umukara, nibindi.
3.Imikorere y'ibikoresho byo gutwika bya B2 grade: board ya polystyrene ikozwe mu buryo bwa molded (EPS), board ya polystyrene ivamo (XPS), polyurethane (PU), polyethylene (PE), n'ibindi.
