2. Ejiri ya na fumigation ọka na refrigeration nke obere ihe nrịbama na ikuku oyi. A na-eji ya dị ka ihe inyeaka na-afụ ụfụ na mmepụta nke polyether urethane foam yana dị ka ihe na-afụ ụfụ maka ụfụfụ polysulfone extruded.
3.Jiri dị ka ihe mgbaze, extractant na mutagen. Ejiri ya na nyocha mkpụrụ ndụ ihe ọkụkụ.
4.Ọ nwere ihe mgbaze dị mma, bụ ihe mgbaze dị ala na-esi ísì ụtọ na obere nsị na enweghị ọkụ n'etiti ihe mgbaze ụlọ ọrụ a na-ejikarị eme ihe, ma nwee ezigbo ihe mgbaze maka ọtụtụ resins, paraffins na abụba. A na-ejikarị eme ihe dị ka onye na-agba agba agba, mmanụ dewaxing ihe mgbaze, onye na-emepụta ihe na-adịghị mma, onye na-emepụta lanolin sitere na ajị na mmanụ oriri sitere na aki oyibo, ihe mgbaze nke ihe nkiri triacetate cellulose. A na-ejikwa ya n'ọtụtụ ebe na eriri acetate, mmepụta fiber vinyl chloride, nhazi na ihe ọkụ ọkụ, refrigerant, urotropine na mmepụta ndị ọzọ.
5.Jiri na ụlọ ọrụ eletrọnịkị. A na-ejikarị eme ihe dị ka ihe nhicha iji wepụ mmanụ.
6.Widely eji dị ka ọkụ retardant mgbaze na a dị nnọọ ala esi ebe. Na mgbakwunye na ịsacha ihe mgbaze maka ụgbọ elu ụgbọ elu, igwe ziri ezi, wdg, a pụkwara iji ya mee ihe dị ka onye na-agbapụ agba agba, a pụkwara ịgwakọta ya na ihe ndị ọzọ na-edozi ahụ ka a ga-eji mee ihe dị iche iche nke ụlọ ọrụ mmepụta ihe.
7.Asịkwara na-eji dị ka ethyl ester eriri mgbaze, eze anestetiiki mpaghara, refrigerant na ọkụ emenyụ gị n'ụlọnga, wdg, bụ a nkịtị eluent maka chromatographic nkewa na mmịpụta nkewa nke nkịtị mgbaze.
8.Jiri dị ka ihe mgbaze na resin na plastic ụlọ ọrụ.
Ihe ndetu nchekwa ngwaahịa:
1.Chekwaa n'ụlọ nkwakọba ihe dị jụụ, ikuku.
2.Chep n'ebe ọkụ na isi iyi ọkụ.
3.Na-echekwa na okpomọkụ na-agaghị agafe 32 Celsius C na iru mmiri na-erughị 80%.
4.Na-edebe akpa ahụ akara.
5.It kwesịrị ịchekwa iche site na ọla alkali na kemịkalụ oriri, ọ dịghịkwa mgbe a ga-agwakọta ya.
6.Equipped na kwesịrị ekwesị iche na quantities nke ọkụ ọgụ ngwa.
7.Ebe nchekwa ahụ kwesịrị ịkwado ngwa ngwa ọgwụgwọ mberede na-agbapụta na ihe ndị dị mma.
