Makina ochotsera manyowa a mtundu wa PP polypropylene (lamba wonyamula) amapangitsa kuti manyowa a nkhuku aume kukhala osavuta kugwiritsa ntchito komanso kuti manyowa a nkhuku agwiritsidwenso ntchito kwambiri. Manyowa a nkhuku alibe kuwiritsa m'nyumba ya nkhuku, zomwe zimapangitsa kuti mpweya wamkati ukhale wabwino komanso zimachepetsa kukula kwa majeremusi. Ulusi wapadera wa mankhwala, polyethylene ndi zinthu zina zoletsa ukalamba zomwe zimagwiritsidwa ntchito zimakhala ndi makhalidwe oletsa kumiza, kuletsa dzimbiri, kutopa ndi zina zotero, zomwe zimapangitsa kuti nthawi yogwira ntchitoyo ipitirire.
Malangizo ogwiritsira ntchito lamba wosamutsa manyowa a PP:
Popeza lamba wotumizira manyowa ndi wotchuka kwambiri popanga ulimi, mitundu yosiyanasiyana ya manyowa, magwiridwe antchito apamwamba, kulemera kochepa, magwiridwe antchito ambiri komanso moyo wautali ndi zinthu zina zomwe opanga amafunikira. Pakupanga mafakitale, kugwiritsa ntchito bwino lamba wotumizira manyowa wa PU ndikofunikira kwambiri, lamba wotumizira manyowa wa PP yemwe akugwiritsidwa ntchito ayenera kulabadira zinthu zotsatirazi:
1. Pewani kuti ma roller aphimbidwe ndi zinthu zomwe zimapangitsa kuti zinthu zisayende bwino, kuti zinthu zisatuluke pakati pa roller ndi tepi, samalani ndi mafuta omwe amalowa m'malo mwa lamba wa PP, koma musawagwiritse ntchito ngati lamba wonyamulira wopaka mafuta.
2. Pewani kuyambika kwa katundu wa lamba woyeretsa.
3. Ngati lamba wonyamulira katundu walephera kugwirizana, chitanipo kanthu kuti mukonze nthawi yake.
4. Lamba likapezeka kuti lawonongeka pang'ono, thonje lopangidwa liyenera kugwiritsidwa ntchito pokonza nthawi yake kuti lisakulire.
5. Pewani lamba wonyamulira katundu kuti atsekedwe ndi choyikapo, chipilala kapena bolodi, ndipo mupewe kuti lisasweke kapena kung'ambika.
