Biodegradable Zaj Duab Xis Hloov Cov Khoom-Phila
Kev siv polylactic acid tam sim no txuas ntxiv dhau cov khoom siv cov hnab ntim khoom xws li hnab ntim khoom, cov yeeb yaj kiab cov ntaub qhwv thiab khob. Ntim khoom tsim los ntawm cov acid txheem acid tau kim, tab sis tau dhau los ua ib qho ntawm cov khoom ntim ntim ntau tshaj plaws. Poly (Lactic acid) tuaj yeem ua rau hauv cov fibers thiab cov yeeb yaj kiab los ntawm extrusion, txhaj tshuaj molding, ncab. Cov dej thiab huab cua permeability ntawm polylactic acid zaj duab xis qis dua li ntawm polystyrene zaj duab xis. Txij li thaum dej thiab roj molecules yog diffused los ntawm amorphus cheeb tsam ntawm polylactic acid zaj duab xis tuaj yeem hloov kho cov crystalline ntawm polylactic acid.
Ntau cov thev naus laus zis xws li annealing, ntxiv nuclearing cov neeg sawv cev, sib txuas ntxiv nrog cov fibers lossis qhia txog cov khoom sib txuas lossis qhia txog cov khoom siv ntawm pla polymers. Polylactic acid tuaj yeem ua tiav zoo li feem ntau thermoplastics rau fiber ntau (piv txwv li, siv cov duab yaj ua cov txheej txheem spinning) thiab ua yeeb yaj kiab. PLA muaj cov khoom zoo sib xws rau pete polymer, tab sis muaj qhov siab tshaj plaws txuas ntxiv txuas kev siv kub. Nrog lub zog saum npoo, PLA muaj cov ntawv luam tawm yooj yim uas ua rau nws dav siv nyob rau hauv 3-d luam ntawv. Lub zog tensile rau 3-D Cov Sta tau txiav txim siab yav dhau los.
SPRA NTA
Lub ntsiab txhais ntawm biodegradable plastics, nws yog los taw rau xwm, ib puag ncig dej, ib puag ncig dej, ib puag ncig dej, cov dej ib puag ncig, kev ua txhaum ntawm cov xwm txheej ntawm qhov muaj xwm txheej, thiab kev cuam tshuam ntawm kev ua haujlwm Rau hauv cov pa roj carbon dioxide (CO2) thiab / lossis methane (ch4), dej (xws li cov roj ntsha tshiab (xws li cov microorganisms, thiab lwm yam) ntawm cov yas.
Daim Ntawv Thov Phila Lub Ntsiab
Nws tuaj yeem hloov cov hnab yas ntim khoom, xws li hnab ntim khoom, hnab ris tsho, hnab khib nyiab, thiab lwm yam.

| Spla-F111 | Lub ntsiab ntawm cov tog-F111 cov khoom yog pla thiab lawv cov khoom tuaj yeem yog 100% biodegred tom qab siv thiab khib nyiab, thiab dej kom tsim cov pa roj hmab thiab dej ib puag ncig. | Thaum siv Spla-F111 Blown zaj duab xis nyob rau hauv lub tshuab zaj duab xis ntau lawm cov kab ntau lawm, cov lus pom zoo ua yeeb yaj kiab kev kub yog 140-160 ℃. |
| Phila-f112 | Lub ntsiab Cheebtsam ntawm Spla-F112 cov khoom yog pla, pbat thiab cov khoom lag luam tuaj yeem siv tau 100% thiab kawg tsim cov pa roj carbon dioxide thiab dej tsis muaj kuab paug. | Thaum siv Spla-F112 Blown zaj duab xis nyob rau hauv Blog zaj duab lug ua yeeb yam ntau lawm kab, cov lus pom zoo ua yeeb yaj kiab kev kub yog 140-160 ℃. |
| Spla-F113 | Lub ntsiab ntawm cov khoom sib xyaw ntawm SPLA-F113 cov khoom yog pla, pbat thiab inorganic tshuaj. Cov khoom tuaj yeem yog 100% biodegraded tom qab siv thiab muab pov tseg, thiab thaum kawg thiab nws tsim cov pa roj carbon dioxide thiab dej tsis muaj kuab. | Thaum siv Spla-F113 zaj duab xis hauv Blown zaj duab lug ua yeeb yaj kiab ntau lawm, cov lus pom zoo ua yeeb yaj kiab kev kub yog 140-165 ℃. |
| Spla-F114 | Cov khoom-F114 yog cov hmoov txhuv nplej siab puv polyethylene hloov masterbatch. Nws siv 50% zaub-derated hmoov txhuv nplej siab es tsis txhob polyethylene los ntawm petrochemical cov peev txheej. | Cov khoom tau sib xyaw nrog polyethylene ntawm lub tshuab ua yeeb yaj kiab ntau lawm. Cov lus pom zoo ntxiv tias 20-60Wt%, thiab Blown zaj duab xis ua qhov kub yog 135-160 ℃. |
