Ifilimu yokudlaiwuhlobo lwemikhiqizo yokupakisha yepulasitiki, ngokuvamile eyenziwa ukusabela kwe-polymerization nge-ethylene njenge-masterbatch.
Ingahlukaniswa izigaba ezintathu
Eyokuqala yi-PE , Isetshenziselwa ikakhulukazi ukupakisha ukudla.Le filimu isetshenziselwa izithelo nemifino esivame ukuyithenga, okuhlanganisa nemikhiqizo eseqediwe ethengwe esitolo.
Eyesibili i-PVC.Le nto ingasetshenziselwa futhi ukupakisha ukudla, kodwa inomthelela othile ekuphepheni komzimba womuntu;
Eyesithathu i-PVDC, esetshenziselwa ikakhulukazi ukupakisha ukudla okuphekiwe, i-ham neminye imikhiqizo.
Yelula ifilimuikhiqizwa kusetshenziswa i-polyethylene ewumugqa we-LLDPE resin kanye nezithasiselo ezikhethekile ze-tackifier.
1. Ukusetshenziswa okuhlukile
Ifilimu Yokudla: ukusetshenziswa okubanzi okubandakanya ukupakishwa kokudla, izithelo, imifino, inyama kanye nokupakishwa kwezihloko.
Ifilimu yokwelula: ukupakishwa, kanye nokupakishwa kokuvikela kwezimpahla ngesikhathi sokuthutha, ikakhulukazi ukuvimbela izinto ukuthi zingahlakazeka noma ziklwebhe.
2. Imininingwane ehlukene
Ubukhulu befilimu yokwelula bukhulu kunefilimu yokudla, futhi ubukhulu bukhulu kunefilimu yokudla.
Ukugoqa kwepulasitiki yasendlini kuvamise ukuba ngu-30cm ububanzi no-10um ukujiya;ifilimu enwetshiwe yezimboni ngokuvamile ingama-50cm ububanzi nama-20um ukujiya.
3. I-stretch ratio ehlukile
Ifilimu yokwelula iyanwebeka kunefilimu yokudla.Ifilimu yokwelula ishaywa ngokuqondile isuka ku-LDPE ngomshini wokubumba igalelo, futhi isilinganiso sayo sokwelula singafinyelela ku-300% -500%.Ngesikhathi esifanayo, ifilimu yokunamathela inamathele esihlokweni, kuyilapho ifilimu elula i-self-adhesive, ehlobene nenani le-polyisobutylene elisetshenzisiwe.
I-LGLPAK igxile ocwaningweni nasekuthuthukisweni nasekukhiqizweni kwemikhiqizo yepulasitiki, ukuhlinzeka amakhasimende ngemikhiqizo egculisayo yilokho esikuphishekelayo.
