Cov khoom siv raw yog txawv. Cov khoom siv raw siv los ntawm cov tshuab tshuab tshuab tshuab feem ntau yog cov khoom siv petrochemical xws li polyethylene (PE) thiab polypropylene (PP). Cov ntaub ntawv no tsis yog ib txwm degradable thiab yuav ua rau muaj kuab paug rau ib puag ncig; thaum biodegradable zaj duab xis tshuab tshuab siv cov ntaub ntawv biodegradable. Cov ntaub ntawv degradable, xws li PLA (polylactic acid), PHA (polyhydroxy acid), thiab lwm yam, cov ntaub ntawv no tuaj yeem decompose sai sai hauv ib puag ncig ntuj thiab txo cov pa phem ib puag ncig.
Cov txheej txheem tsim khoom thiab cov txheej txheem sib txawv. Kev tsim cov txheej txheem ntawm cov tshuab tshuab tshuab zoo tib yam yog qhov yooj yim, feem ntau yog melting thiab extruding petrochemical cov ntaub ntawv rau hauv cov yeeb yaj kiab; biodegradable zaj duab xis tshuab tshuab xav tau kev tswj xyuas meej dua ntawm txhua qhov txuas hauv cov txheej txheem tsim khoom, vim tias kev tsim cov khoom siv biodegradable yuav raug rau ntau cov txheej txheem thiab kev ua haujlwm thev naus laus zis.
Daim ntawv thov kev cia siab yog txawv. Cov pa phem ib puag ncig los ntawm cov ntaub ntawv ntawm cov tshuab tshuab tshuab tsis tuaj yeem tsis quav ntsej, thiab nws qhov kev cia siab ntawm daim ntawv thov raug txwv; thaum cov ntaub ntawv siv nyob rau hauv biodegradable zaj duab xis tshuab tshuab yog biodegradable thiab yuav tsis ua paug rau ib puag ncig, yog li ntawd lawv muaj zoo dua daim ntawv thov.
Cov cuab yeej nta txawv. Lub cev muaj zog ntawm biodegradable zaj duab xis tshuab tshuab yog qhov muaj zog dua, cov ntsia hlau siv cov ntsia hlau siab ceev, kev tswj qhov kub thiab txias yog qhov tseeb dua, lub thav duab yog siab dua los muab cov cua txias kom ntev dua, thiab siv ob qhov chaw nres nkoj cua txias. kom ua tiav uniformity thiab siab ceev ntawm txias. . Tsis tas li ntawd, biodegradable zaj duab xis tshuab tshuab xav tau siab precision hauv kev xaiv cov khoom siv hluav taws xob thiab induction probes. Cov qauv kev kub ceev feem ntau yog nruab nrog cov tshuab rewinding tsis siv neeg los hloov kho kom nrawm nrawm, thaum phau ntawv rewinding muaj qee yam kev pheej hmoo.
Cov yam ntxwv ntawm cov khoom sib txawv. Cov yeeb yaj kiab uas tsim los ntawm biodegradable zaj duab xis tshuab tshuab yog cov dej-soluble biodegradable yas xws li PLA, PBAT, thiab PVA. Cov ntaub ntawv no tau siv dav hauv kev ntim kua, luam ntawv lamination, khaub ncaws thiab ntim khoom, ntim khoom lag luam thiab lwm yam. Cov hnab ua los ntawm cov khoom siv biodegradable muaj zog dua li ib txheej thiab tuaj yeem muaj ob txheej xim xim.
