Isikhwama esilukiweyo siyisikhwama sepulasitiki esisetshenziswa kakhulu, ikakhulukazi esenziwe nge-polyethylene noma i-polypropylene, esinwetshwa sibe usilika oyisicaba, bese selukwa, selukiwe futhi sifakwe esikhwameni.Ngenxa yokuthi amandla, ukuqina nokucaca kwe-polypropylene kungcono kune-polyethylene, ngakho-ke isetshenziswa kakhulu, indima yezikhwama ezilukiweyo nayo ibanzi kakhulu.Zivame ukusetshenziswa njengezikhwama zokupakisha futhi zingasetshenziswa ukupakisha imikhiqizo yezimboni nezolimo.Ukudla, njll Ngaphandle kwalokho, ezokuvakasha.Izikhwama ezilukiweyo nazo ziyasetshenziswa ekulweni nezikhukhula nasekusizeni izinhlekelele.
Isikhwama esilukiweyo, esaziwa nangokuthi isikhwama se-snakeskin, siwuhlobo lwesikhwama sepulasitiki, esisetshenziselwa kakhulu ukupakisha, khona-ke iyini impahla yesikhwama esilukiwe sepulasitiki?Ngokuvamile, izikhwama ezilukiwe zinezinto ezimbili zokusetshenziswa:
1. I-polyethylene
Eyaziwa nangokuthi ipulasitiki ye-PE iyinhlaka ye-thermoplastic eyenziwe nge-ethylene polymerization.Isikhwama esilukiwe sepulasitiki se-polyethylene sisebenza kahle, kepha i-polyethylene iyazwela ekucindezelekeni kwemvelo, ukumelana nokushisa okubi nokuguga, ngakho-ke ayisetshenziswa kancane eChina.
2. I-Polypropylene
Ngokuvamile, izikhwama eziningi ezilukiwe e-China zenziwe nge-polypropylene.I-Polypropylene (PP) inhlaka ye-thermoplastic eyenziwe nge-acrylic polymer enezinto ze-isotropic.Okungahleliwe futhi intergauge ukucupha ezintathu, amandla ayo.Ukuqina nokungafihli kungcono kune-polyethylene, futhi kungashintshwa futhi kwengezwe ama-antioxidants ukunqoba ukumelana nomthelela wokushisa okuphansi, ukushiyeka okulula kokuguga.
Emikhiqizweni yepulasitiki, i-plastic braid iwuhlobo lwezinto eziguquguqukayo ezinamandla amakhulu okuphuka, okuhlobene nesakhiwo sayo samangqamuzana, i-crystallinity, isiqondiso sokubhala kanye nohlobo lokungezelela.Uma umluko wepulasitiki ukalwa ngamandla athile (amandla/amandla adonsela phansi athile), ungaphezulu noma useduze kwento yensimbi.
Ezingeni lokushisa lasekamelweni, indwangu eboshwe ngepulasitiki imelana ngokuphelele nokuguguleka kwamanzi, futhi izinga lokumunca amanzi lingaphansi kuka-0 phakathi namahora angu-24.01%.Ukungena kwamanzi nakho kuphansi kakhulu.Emazingeni okushisa aphansi, iba crunchy.Imiluko yepulasitiki ayikhuntile.
