Bokosi la pulasitiki ndi mtundu wa zida zosungira zomwe zimagwiritsidwa ntchito posungira magawo osiyanasiyana. Ili ndi mawonekedwe a kukana kwa asidi ndi alkali, kutsutsana kwamafuta, yopanda poizoni komanso yopanda fungo, yosavuta kuyeretsa, yolongosoka bwino, komanso yosavuta kuyisamalira. Malinga ndi mawonekedwe, nthawi yogwiritsira ntchito, yonyamula mphamvu ndi kapangidwe kake, imagawika m'magulu awiri: msonkhano wamba wama bokosi olumikizidwa ndi bokosi lolimbitsa. Kodi ndi mitundu iti yomwe mitundu iwiri yamabokosi amafikira?
Bokosi losungidwira limagwiritsa ntchito co-polypropylene ngati zopangira, zomwe zimakhala ndi mawonekedwe abwino, kulemera pang'ono, moyo wautali, kukana zidulo ndi alkalis, ndikuwongolera bwino zinthu. Itha kugwiritsidwa ntchito molumikizana ndi mashelufu opepuka, makabati osungira, okonza zinthu, ndi zida zogwirira ntchito ndi matabwa opachika. Kugwiritsa ntchito bokosi lazopachika kumbuyo lolimba kwambiri kumapulumutsa malo ndikuchepetsa ndalama.
Chidebe chosungika chitha kuphatikizidwa, ndipo chimagwiritsidwa ntchito pamagetsi, makina, mankhwala ndi mafakitale ena. Itha kuphatikizidwa kukhala malo osiyanasiyana ogwiritsira ntchito malinga ndi zochitika zosiyanasiyana. Imasinthika pakugwiritsa ntchito ndipo imasunga bwino malo. Ikasungidwa ndikugwiritsidwa ntchito mosungira, imatha kupewa kukhazikitsa mashelufu, kupulumutsa ndalama.
