Igipimo ngenderwaho cy'ubushyuhe bwa UL94 V-0

Igipimo ngenderwaho cya UL94 V-0 cyo gutwika ni igipimo cy'ingenzi mu bijyanye n'umutekano w'ibikoresho, cyane cyane ibya pulasitiki bikoreshwa mu bikoresho by'amashanyarazi n'iby'ikoranabuhanga. Igipimo ngenderwaho cya UL94 V-0 cyashyizweho na Underwriters Laboratories (UL), ikigo mpuzamahanga gishinzwe gutanga ibyemezo by'umutekano, cyagenewe gusuzuma imiterere y'ibikoresho bya pulasitiki byo gutwika. Iri hame ni ingenzi kugira ngo ibikoresho bikoreshwa mu bicuruzwa bikoreshwa n'inganda bidatera imbere mu gukwirakwiza inkongi, bityo bikazamura umutekano muri rusange.

Igipimo cya UL94 V-0 ni kimwe mu bigize uruhererekane rwagutse rwa UL94, rurimo ibyiciro bitandukanye nka UL94 V-1 na UL94 V-2, buri kimwe kigaragaza urwego rutandukanye rw'ubudahangarwa bw'umuriro. "V" muri UL94 V-0 isobanura "Ubutambitse," yerekeza ku isuzuma ry'ubudahangarwa bw'umuriro rikoreshwa mu gusuzuma ubudahangarwa bw'ibikoresho. "0" igaragaza urwego rwo hejuru rw'ubudahangarwa bw'umuriro muri uru rwego, bivuze ko ibikoresho bigaragaza ubudahangarwa buke.

Kimwe mu bintu by'ingenzi by'ingenzi mu gipimo cya UL94 V-0 ni uburyo bwo gupima buhamye. Ibikoresho bikorerwa isuzuma ry’umuriro uhagaze, aho icyitegererezo cy’ibikoresho gifatwa gihagaze kigashyirwa ku muriro mu gihe cy’amasegonda 10. Hanyuma umuriro urakurwaho, hanyuma igihe bifata kugira ngo ibikoresho bihagarike gushya kigapimwa. Iyi gahunda isubirwamo inshuro eshanu kuri buri cyitegererezo. Kugira ngo ugere ku gipimo cya UL94 V-0, ibikoresho bigomba kuba byujuje ibi bikurikira: umuriro ugomba kuzimya mu masegonda 10 nyuma ya buri gikoresho, kandi nta bitonyanga by’umuriro bitwika ikimenyetso cy’ipamba kiri munsi y’icyitegererezo byemewe.

Akamaro k'ibipimo ngenderwaho bya UL94 V-0 ntigakwiye gukabya. Muri iki gihe aho ibikoresho by'ikoranabuhanga n'ibikoresho by'ikoranabuhanga bikwirakwira hose, ibyago byo kwangirika kw'inkongi byiyongereye cyane. Ibikoresho byujuje ibipimo ngenderwaho bya UL94 V-0 ntibikunze gutwika no gukwirakwiza inkongi, bityo bikagabanya ibyago byo kwangirika kw'impanuka ziterwa n'inkongi. Ibi ni ingenzi cyane ku bicuruzwa bikoreshwa ahantu hashobora gutera ibyago byinshi nko mu nganda, mu bigo nderabuzima no mu buryo bwo gutwara abantu n'ibintu rusange.

Byongeye kandi, kubahiriza amahame ya UL94 V-0 akenshi ni ngombwa kugira ngo habeho kwemerwa n'amategeko no kwemerwa ku isoko. Abakora aya mahame bashobora kwizeza abaguzi n'inzego zishinzwe kugenzura ko ibicuruzwa byabo byujuje ibisabwa mu mutekano. Ibi ntibikomeza izina ry'ikirango gusa ahubwo binatanga amahirwe yo guhangana ku isoko.

Uretse umutekano, amahame ya UL94 V-0 afite n'ingaruka ku bukungu. Ibicuruzwa byujuje aya mahame ntabwo bikunze kugira ingaruka ku nkongi z'umuriro, ibyo bikaba byatera kwangirika gukomeye no kugira ibibazo by'uburyozwe. Kubwibyo, gushora imari mu bikoresho byubahirije amahame ya UL94 V-0 bishobora gutuma inganda zizigama amafaranga mu gihe kirekire.

Mu gusoza, amahame agenga ubushyuhe bwa UL94 V-0 afite uruhare runini mu kurinda umutekano w’ibikoresho bya pulasitiki bikoreshwa mu bikorwa bitandukanye. Uburyo bwo kubigerageza buhamye hamwe n’uburyo burambuye bwo gushyira mu byiciro bitanga igipimo cyizewe cy’ubudahangarwa bw’umuriro w’ibikoresho. Uko ikoranabuhanga rikomeza gutera imbere n’ubukene bw’ibikoresho bihamye bukiyongera, amahame agenga UL94 V-0 azakomeza kuba igikoresho cy’ingenzi ku bakora ibikoresho ndetse n’abashinzwe umutekano.

Shifang Taifeng New Flame Retardant Co, Ltd.ni uruganda rufite uburambe bw'imyaka 22 rwibanda ku gukora ibiyobyabwenge bigabanya umuriro bya ammonium polyphosphate, ibyo dukora byoherezwa mu mahanga cyane.

Imashini yacu igabanya umuriro ihagarariyeTF-201Ntibingiza ibidukikije kandi birahendutse, ikoreshwa mu gusiga irangi ry’imbere mu gitambaro, mu gusiga irangi ry’inyuma mu myenda, mu pulasitiki, mu mbaho, mu nsinga, mu gufunga no mu gusiga ifuro rya PU.

Niba ukeneye kumenya amakuru arambuye, twandikire.
