Tambayoyin da ake yawan yi (FAQs)

Tambaya: Shin TMAH lafiya ne don amfani?

A: A'a. TMAH yana da lalacewa sosai kuma yana da guba sosai. Dole ne a kula da shi tare da taka tsantsan ta amfani da cikakken kayan kariya na mutum da ingantattun sarrafa injiniyoyi. Duk wani bayyanar fata yana buƙatar kulawar likita nan da nan.

Tambaya: Me yasa aka fi son TMAH akan KOH ko NaOH a cikin semiconductor?

A: TMAH ba shi da ƙarfe-ion-kyauta, yana hana gurɓatar wafers da na'urori yayin samar da kyakkyawan etching da haɓaka aiki.

Tambaya: Menene babban haɗarin TMAH?

A: Yana haifar da ƙonewa mai tsanani ga fata da idanu kuma yana iya haifar da guba na tsari ta hanyar tsotse fata. Hakanan yana da illa ga muhalli.

Tambaya: Yaya ya kamata a adana TMAH?

A: Ajiye a cikin kwantena da aka rufe sosai a cikin sanyi, busasshiyar wuri mai cike da iska daga acid, oxidizers, da iska.

Tambaya: Za a iya amfani da TMAH a abinci ko aikace-aikacen magunguna?

A: A'a. TMAH an yi shi ne don masana'antu, dakin gwaje-gwaje, da amfani da kayan lantarki kawai kuma bai dace da abinci, magunguna, ko aikace-aikacen kayan kwalliya ba.
