Matayala ambiri opangidwa kumene kapena okonzedwanso ayamba kugwiritsa ntchito pulasitiki yopanda madzi. Pakadali pano, gawo la pulasitiki mu msika wapabanja lakwera mwachangu. Ndi kutchuka kwambiri kwa matope osambira a pulasitiki, thumba la pulasitiki lingasungidwe bwanji ndikusungidwa?
1. Pambuyo pa kuvomerezedwa kwa dziwe lakusambira la Mool laterproof, wogwiritsa ntchitoyo agawire munthu wodzipereka kuti aziyang'anira.
2. Amaletsedwa kubowola mabowo kapena kukhudza zinthu zolemera pa chingwe chamadzi chokongoletsera: sichimaloledwa kuyika kapena kuwonjezera zopanga zokongoletsera madzi okongoletsera. Maofesi akafunika kuwonjezeredwa ku PVC lamer, zofananira ndi zokongoletsa ziyenera kuchitika.
3. Malowedwe osambira a pulasitiki a pulasitiki ayenera kuyika madzi oyeretsa m'madzi onse 7-15.
4. Zimaletsedwa kuti muwonjezere mankhwala oyambira oyambirira mu dziwe la PVC Linmer kusambira. Mankhwala ayenera kuchepetsedwa makonzedwe.
Mtengo wa PH wa dziwe losambira liyenera kuwongoleredwa mgulu la 7.2 mpaka 7.6.
5.
6. Ndi zoletsedwa kugwiritsa ntchito mabulosi achitsulo kapena zida zina zakuthwa kuti muyeretse pamwamba pa PVC.
7. Kwa madontho akulu omwe ndi ovuta kusamba, zoyeretsa zamankhwala zotsika a asidi zitha kugwiritsidwa ntchito kuyeretsa.
8. Mukamagwiritsa ntchito dziwe losambira, kutentha kozungulira kumayenera kulamulidwa mu mitundu ya 5-40 ℃. Chingwe chopanda madzi chiyenera kusamalidwa molingana ndi malamulo osakira a National Tool ndi Masamalire ndi njira zamagetsi zamadzi zomwe zilipo.
9. Pamene kutentha kwa kutentha kuli pansi pa 5 ℃, zida zotsutsana ndi zodetsa (monga zakumwa zonyansa zodziwika, etc.) ziyenera kukhazikitsidwa kapena kugwiritsidwa ntchito mu dziwe lokongoletsa filimu isanayambe kuzizira. Nthawi yomweyo, madzi a dziwe amayenera kuthiridwa, ndi dothi ndi madontho pansi pa chingwe chopanda madzi ziyenera kutsukidwa munthawi yake, ndipo njira zotchingira ziyenera kutengedwa.
