Umbala webhande lokuhambisa elinokushisa okuphansi uluhlaza, ubuso bufana nebhande lokuhambisa elivamile le-PVC eliluhlaza, kodwa ukwakheka akufani, sengeze i-ejenti engabanda engqimbeni yerabha ye-PVC, engagcini nje ngokuqinisekisa amandla okuthwala umthwalo webhande lokuhambisa, kodwa futhi inciphisa ukujiya okuphelele kwebhande lokuhambisa, okunciphisa isisindo sonke sebhande lokuhambisa, futhi kushintsha uhlobo lwebhande lokuhambisa, linezici zokuqina okuphezulu, ukumelana nokushayisana, ukumelana nokubanda, njll., futhi liyakwazi ukwanelisa ukuhanjiswa kwemvelo kwezinga lokushisa lama-degrees angaphansi kwezinga -10 ~ -40.
Izici zebhande lokuhambisa elingamelana nokushisa okuphansi:
1, ukumelana nokubanda. I-plasticizer evamile ye-PVC ku-minus 40 ℃ ayiqini, ayijiyile. Ihlolwe izikhathi eziningi ngokuphindaphindiwe, inekhwalithi eqinile kanye nokugeleza koketshezi okuzinzile.
2, ayibhamuzi uwoyela. I-PVC okuvamile plasticizer kanye ne-PVC okuvamile resin ukuncibilika, ukuzinza ukushisa isikhathi eside, ukuxazulula inkinga yokuwa kwamafutha.
3. Thuthukisa ukukhanya nokucaca kwemikhiqizo.
4, Nciphisa izindleko zabakhiqizi bemikhiqizo ejwayelekile ye-PVC.
5, ukuvikelwa kwemvelo kwe-ester ye-Dioctyl kanye ne-ester ye-dibutyl akukuhle njenge-ester yesitshalo sokwenziwa, i-ester yesitshalo sokwenziwa ayinayo i-16p. Futhi ekuthuthweni akukho zimpahla eziyingozi, ezingashisi, kunzima ukuzishintsha.
