Ukusetyenziswa kweeplasitiki zokwenziwa kwathatyathwa kwi-petroleum kucengwe ngenxa yemicimbi eyaziwayo kakhulu yongcoliseko olumhlophe. Ukufuna izixhobo zekhabhoni ezihlaziyiweyo njengenye indlela ebaluleke kakhulu kwaye ingxamisekile. I-Polylactic Acid (i-pla) ithathelwe ingqalelo enye into enokubakho yokuthatha indawo esekwe kwi-petroleum-esekwe ngokwesiqhelo. Njengobutyebi obufikelelekayo ovela kwi-biomass ngeempawu ezifanelekileyo zoomatshini, i-biomatisic efanelekileyo, kunye nokuhlanjwa, iplagi inamava okuqhubela phambili kwintengiso yobunjineli, izixhobo zokupakisha, izibonelelo zokupakisha. Nangona kunjalo, ukumelana kobushushu obuphantsi kunye nobunzima obuphantsi bungaphezulu kakhulu kuluhlu lwezicelo.

Ukudibanisa i-Polylactic Acid (i-PLA) kunye ne-thermoesticlistic i-posicone Polytorthane (TPIU) yenziwa kwi-Toughen PLA.

Iziphumo zibonise ukuba i-TPIU yadityaniswa ngempumelelo i-PLA, kodwa akukho nto intshabalalo yekhemikhali yenzeka. Ukudityaniswa kwe-TPIU kwakungekho mphumo mveliso weqondo lokushisa leglasi kunye nokunyibilika kweqondo le-pla, kodwa kunciphise i-crystallity yetlu.

I-Morphology kunye ne-Dynamic Meperation Iziphumo ze-Dynamic Pondoral iziphumo zibonakalise ukungasebenzi kakuhle kwe-thermodynamic phakathi kwe-pla kunye ne-tpsiu.

Izifundo zokuziphatha ze-RIOOOOLOO zibonise ukuba i-Plate / Tpsiu melt yayiyindlela ye-pseudoplastic. Njengomxholo onyuke nge-TPIU, u-Vecofity obonakalayo wePP / TPIU Clends ubonise umkhondo wokunyuka okokuqala kwaye emva koko uwa. Ukongezwa kwe-TPIU kwanefuthe elibonakalayo kwiipropathi zoomatshini wePP / TPSIU. Xa umxholo we-tpsiu wayeyi-15 wt%, i-elongingey ekhefu kwi-pla / i-TPIU BILD ifikelele kwi-22.3% (ifuthe lokufikelela kwi-SPRE), iphakamisa isiphumo esihle kakhulu.

Xa kuthelekiswa ne-TPU, i-TPIU inesiphumo esingcono kwi-PLA kwisandla esinye kunye nokuchasana nobushushu kwelinye icala.

Nangona kunjalo,Isilika Si-tpvyindawo emangalisayo ye-therciastic ye-thertolistic esekwe kwi-Elastone-esekwe kwi-Elastone. Isongele inkxalabo eninzi ngenxa yomphezulu wayo onobuhlobo obuqhelekileyo kunye nombulelo onobuhlobo, ukungavisisani okungcono komdaka, ukungavisisani okungcono, ukungabinayo i-pristriber kunye neoyile yokuthambisa, akukho vumba.

Kunye nefuthe elingcono lefuthe kwiPlati.

Esi sixhobo sikhuselekileyo sezinto ezikhuselekileyo nezendalo, sinika indibaniselwano elungileyo yepropathi kunye nezibonelelo ezivela kwi-thermoplastics kunye nerabha ngokupheleleyo. I-SUITS YOBUCHULE BOKUGQIBELA
