I-API 5L X42 PSL1 Ukuqulunqwa kwemichiza
Iimfuno zemichiza ye-PSL1 zikhululekile, ngenjongo yokuqinisekisa ukuwelda kunye nokuqina kwemathiriyeli.
I-API 5L X42 PSL2 Ukuqulunqwa kwemichiza
I-PSL2 inolawulo olungqingqwa lokwakheka kweekhemikhali ukuqinisekisa umgangatho ophezulu kunye nokusebenza kweendawo ezifuna kakhulu kunye nokusetyenziswa.
Amabakala athile etyhubhu yePSL2 ayilelwe ngokukodwa usetyenziso olukhethekileyo, kubandakanywa izimamva zemathiriyeli "S" kunye no "O".Isimamva "S" sibonisa ukuba umbhobho uyilelwe imekobume emuncu, ngelixa imibhobho enesimamva "O" iyilelwe iimeko zeqonga elingaphesheya konxweme.
Ngenxa yokuba le mimandla iyingozi kakhulu, ukuxhathisa ukubola kombhobho wensimbi kuphuculwe ngokutshintsha ukubunjwa kweekhemikhali.
