1.Itumizwa mu mahanga ryujuje ubuziranenge polystirene ikoreshwa nkibikoresho fatizo.Ubuso bwibiryo bya Petri biroroshye kandi muri rusange gukorera mu mucyo ni hejuru, bikaba byoroshye gukura no kwaguka kwingirabuzimafatizo zifatiye ku rukuta.

2.Gukoresha hamwe na okiside ya Ethylene kugirango urebe neza, ifata amoko mpuzamahanga amarira.

3.Bikwiriye ingirabuzimafatizo, umuco wa bagiteri, kwipimisha ibiyobyabwenge, nibindi birakwiriye no guterwa muri laboratoire, kwandika, gutandukanya abakoloni no kwezwa, nibindi.

Uburyo bwo Gusukura

Mubisanzwe, hari intambwe enye: gushiramo, gukaraba, gutoragura, no gukora isuku.

1. Kunyunyuza: ibikoresho bishya cyangwa byakoreshejwe ibirahuri bigomba gushirwa mumazi meza kugirango ubanze woroshye kandi ushonga imigereka.Ibikoresho bishya byibirahure bigomba guhanagurwa gusa namazi ya robine mbere yo kubikoresha, hanyuma bigashiramo ijoro ryose hamwe na aside hydrochloric 5%;Ibikoresho bikoreshwa mubirahuri bikubiyemo proteine ​​nyinshi hamwe namavuta, ntabwo byoroshye koza nyuma yo gukama, bityo bigomba guhita byinjizwa mumazi meza kugirango byoge nyuma yo kubikoresha.

2. Kwoza: shyira ibirahuri byometse mumazi yogeje hanyuma uhanagure inshuro nyinshi ukoresheje brush yoroshye.Ntugasige inguni zapfuye, kandi wirinde kwangirika hejuru yibikoresho.Koza kandi wumishe ibirahuri byogejwe kugirango ushire.

3. Gutoragura: gutoragura ni ugucengera imiyoboro yavuzwe haruguru mugisubizo cyogusukura, kizwi kandi nkumuti wa acide, kandi ugakuraho ibintu bishobora kuba bisigaye hejuru yubwato binyuze muri okiside ikomeye yumuti wa aside.Gutoranya ntibigomba kuba munsi yamasaha atandatu, mubisanzwe ijoro cyangwa birenga.Witondere mugihe ushyira no gufata ibikoresho.

4. Gukaraba: ibikoresho nyuma yo koza no gutoragura bigomba gukaraba byuzuye amazi.Niba ibikoresho byogejwe neza nyuma yo gutoranya bigira ingaruka nziza kubitsinzi cyangwa kunanirwa kwumuco.Nyuma yo gukaraba intoki zashizwemo, buri cyombo kigomba kuzuzwa inshuro nyinshi "kuzuza amazi ubusa" byibuze inshuro 15, hanyuma ukarangiza amazi yatoboye inshuro 2-3, akuma cyangwa akuma hanyuma agapakira kugirango ahagarare.

 

Icyapa cy'umuco

1.Kwemeza tekinoroji yo gutunganya hejuru yubutaka hamwe nuburyo bwo gukora ibikoresho bya polymer nkeya.

2.Guhuza igifuniko hamwe nisahani yo hepfo bifite ubukana buringaniye, bworoshye guhumeka kandi bikarinda kwanduza icyapa cyumuco cyangwa guhumeka kwamazi.

3.Ibisobanuro bitandukanye bihura n'imico itandukanye.
