Mabizinesi amakulitsa kupanga, madongosolo oyambitsidwa nthawi yomweyo adayambitsanso zopangira, makamaka pbat, ma pbs ndi zida zina za membrane m'miyezi 4 yokha, mtengo womwe udachitika. Chifukwa chake, zinthu za m'lifupi ndi mtengo wokhazikika zimakopa chidwi.
Poly (lactic acid) (pla) Mapeto ake, monga co2 ndi H2O.
Chifukwa cha zabwino zake zolimbitsa mphamvu, kukonza kosavuta, malo okhazikika, bioocomations, kumagwiritsidwa ntchito kwambiri paulimi, chakudya chamankhwala ndi minda ina. Udzu wopanda kanthu walandira chidwi kwambiri m'zaka zaposachedwa.
Poyankha ku Plapt Clearder, udzu wa pepala amagwiritsidwa ntchito kwambiri ku China. Komabe, zovala za pepala zimatsutsidwa kwambiri chifukwa chosagwiritsa ntchito bwino ntchito. Opanga kwambiri amayamba kusankha zida zosinthidwa kuti zipange udzu.
Komabe, ngakhale kuti polylactic acid ali ndi mphamvu zamakina, kutalika kwake kotsika (nthawi zambiri kumakhala kochepera 10%) komanso kuwongolera koyenera kumachepetsa ntchito mu udzu.
Chifukwa chake, chopondera chakhala mutu wankhani wotentha pakalipano. Otsatirawa ndi kupita patsogolo kwapakati pa kafukufuku wotsatsa.
Poly - lactic acid (pl) ndi imodzi mwazinthu zokhwima zokhazikika kwambiri. Zida zake zopangira ndizochokera kutsamba chosinthira, chimanga, cha ulimi wa zamalonda, etc., ndipo limakhala ndi biodegradiyimily. Play Wabwino Kwambiri, ofanana ndi mapulaneti a polypropherlene a pp ndi pulasitiki ya zinyama m'minda ina. Pakadali pano, plash ili ndi gloss yabwino, kuwonekera, kumva ndi dzanja la antibacterial
Pulogalamu Yopanga
Pakadali pano, Plawi ili ndi njira ziwiri zopangira. Chimodzimodzi ndi consination mwachindunji polymerization, mwachitsanzo, lactic acid ndi madzi osungunuka komanso ochepetsedwa pansi pa kutentha komanso otsika. Njira yopanga ndi yosavuta ndipo mtengo wake ndi wotsika, koma kuchuluka kwa zochulukitsa sikuli bwino, ndipo ntchito yothandiza kwambiri siili bwino.
Wina ndi mphete ya lactade - kutsegula polymerization, komwe ndi njira yopangira.
Kuwonongeka kwa pla
Pla ndi yokhazikika kutentha kwa firiji, koma amachepetsa mosavuta mu CO2 ndi madzi mu malo okwera kwambiri, malo oyambira ndi microber. Chifukwa chake, zinthu zam'magulu zimatha kugwiritsidwa ntchito mosavomerezeka mkati mwa nthawi yovomerezeka komanso yowonongeka nthawi ya nthawi atachotsedwa poyikidwa kuwongolera chilengedwe ndikunyamula.
Zinthu zomwe zimakhudza kuchepa kwa Volecular makamaka kunenepa, ma crystalline, kutentha kwa micrest, kutentha, nthawi ya chinyezi, nthawi yowunikira zachilengedwe.
Mapulogalamu ena amatha kukhudza kuchuluka kwa kuwonongeka.
Mwachitsanzo, pla yowonjezera ufa wa nkhuni kapena chimbale cha chimanga chimatha kuthamanga kwambiri kuchuluka kwa kuchepa.
Kuyendetsa bwino
Chikumbutso chimatanthawuza luso la zinthu kuti muchepetse gawo la mpweya kapena nthunzi yamadzi.
Katundu wotchinga ndi wofunikira kwambiri pazida za matepu. Pakadali pano, thumba la pulasitiki lopanda tanthauzo pamsika ndi ma pl / pbat mawonekedwe.
Zotchinga za filimu yokonzedwa bwino zitha kuwonjezera pulogalamu yofunsira.
Zinthu zomwe zikukhudza katundu wa plar cocor zimaphatikizapo zinthu zamkati (ma delecular ndi ma crystalrization) ndi zinthu zakunja (kutentha, chinyezi, mphamvu yakunja).
1. Kutenthetsa filimuyo kumachepetsa katundu wake wotchinga, kotero pla sioyenera kudya chakudya chomwe chimafunikira kutentha.
2.
Chiwerengero cha tunsin chikachuluka kuchokera 1 mpaka 6.5, makiyirizidwe aphulika amawonjezeka kwambiri, kotero katundu wotchinga wasinthidwa.
3. Kuwonjezera zotchinga zina (monga dongo ndi fiber) ku ma PLIRX imatha kukonza katundu wa plall.
Izi ndichifukwa choti chotchinga chimathandizira njira yokhotakhota yamadzi kapena njira yolumikizira mafuta amolekyulu yaying'ono.
4. Chithandizo cholumikizira pa filimu ya pulama amatha kusintha katundu wotchinga.
