3.2 Mapulogalamu:
CAS 50662-95-8 imakhala yofunika kwambiri m'mafakitale osiyanasiyana ndi malo ofufuza chifukwa chapadera.Ntchito zina zodziwika bwino ndi izi:
- Zida zamagetsi, monga zida zotetezera ndi matabwa ozungulira.
- Ma composites apamwamba kwambiri, pomwe chigawocho chimalimbitsa mphamvu zamakina ndikuwongolera kukhazikika kwamafuta.
- Thermoplastic resins, kupereka kukana kutentha ndi kukhazikika kwa mankhwala.
- Zopaka ndi zomatira, kukulitsa kulimba komanso kukana zinthu zosiyanasiyana zachilengedwe.
3.3 Ubwino:
Posankha gulu lathu lapamwamba la CAS 50662-95-8, mutha kuyembekezera zotsatirazi:
- Kukhazikika kwapadera kwamafuta, kuwonetsetsa kuti malonda anu amatha kupirira kutentha kwambiri popanda kuwonongeka.
- Mphamvu zamakina apamwamba, kupititsa patsogolo moyo wautali komanso kulimba kwa zida.
- Kukana kwamphamvu kwamankhwala, kuteteza kuzinthu zowononga.
- Zabwino kwambiri zamagetsi, zomwe zimathandizira kuti pakhale zida zamagetsi zamagetsi.
- Ntchito zosunthika m'mafakitale osiyanasiyana, zomwe zimapereka mayankho anzeru pazosowa zanu.
