Introduction to biaxially oriented polylactic acid BOPLA

Gabatarwa zuwa polylactic acid BOPLA mai daidaitacce

Biaxially daidaitacce poly (lactic acid) fim (BOPLA) wani nau'in fim ne mai ƙarfi mai ƙarfi wanda aka samo bayan madaidaiciyar madaidaiciya da madaidaiciyar kayan polylactic acid da crystallization.Biaxial shimfidawa tsari ya hada da Mataki-mikewa, 2. Mechanical lokaci guda mikewa da m LISIM lokaci daya mikewa, kamar yadda aka nuna a cikin Hoto 1. Idan aka kwatanta da sauran hanyoyin sarrafawa, tsarin shimfidawa na biaxial yana inganta tsarin kwayoyin halitta na kayan PLA, yana ba da kayan PLA tare da babban ƙarfi babban juriya na zafi, kuma yana rage kauri na samfurori don cimma mafi kyawun amfani da kayan.BOPLA yana da abũbuwan amfãni daga daidaitattun ingantattun kaddarorin injina na tsaye da kwance, babban fahimi, babban fa'ida da ingantaccen bugu.Zai iya maye gurbin fim ɗin da ake amfani da shi a halin yanzu a cikin kayan aikin e-kasuwanci, abinci mai ƙima, samfuran lantarki, lamination takarda-roba da sauran fannoni.

Hoto 1. Tsarin tsarin shimfidawa na biaxial

BOPLA yana da fa'idodi guda uku a aikace-aikacen kasuwa.

Na farko, BOPLA shine mafi kyawun fim na gaskiya na tushen halittu akan kasuwa.Godiya ga halaye na kayan aiki da machinability na PLA, BOPLA yana da ƙarancin matakan samarwa da ƙarancin sarrafa aiki, kuma yana da fa'idodin hana ruwa da bugu na fim ɗin polymer na gargajiya, wanda ya sa ya sami kyakkyawan fata a fagen aikace-aikacen fim na bakin ciki.

Na biyu, BOPLA yana da halayen lalacewa masu iya sarrafawa.A ƙarƙashin yanayin ajiya na al'ada, BOPLA na iya kula da kyakkyawan aiki don ba da garantin rayuwar samfuran da kuma guje wa raguwar rayuwar samfuran tasha saboda saurin lalacewa.A karkashin yanayin takin, BOPLA na iya samun kauri mai kauri a ƙarƙashin kayan aikin injin guda ɗaya, ta yadda zai iya ƙasƙanta da sauri a yanayin takin.

Na uku, BOPLA ya cika buƙatun ajiyar kayayyaki na al'ada da jigilar kayayyaki, kuma yana da tushen aikace-aikacen masana'antu.A cikin gwajin saurin tsufa na BOPLA (FIG.2), ƙarfin ɗaure yana lalata kashi 4.5 kawai bayan shekara 1 da 5.2% bayan shekaru 2.Ƙarfin rufewar zafi yana rage 12.8% bayan shekara 1, wanda ya dace da buƙatun aikin rufewar zafi.A cikin gwaje-gwajen teku na BOPLA (Xiamen-Antwerp, FIG. 3), babu wani canji mai mahimmanci a cikin kayan fim da bayyanar.
