Kev ntsuas qhov hnyav ntawm biodegradable ib puag ncig tus phooj ywg lub hnab yog tib yam li cov hnab yas zoo tib yam, ob qho tib si tau txais los ntawm kev suav cov khoom ntawm qhov ntom thiab ntim. Raws li cov ntaub ntawv muab los ntawm Baidu Zhidao, qhov hnyav ntawm lub hnab yas tuaj yeem suav nrog cov qauv hauv qab no: hnyav {{0}} ntom x ntim. Tshwj xeeb tshaj yog rau cov hnab yas, yog tias peb paub qhov loj thiab tuab ntawm lub hnab yas, peb tuaj yeem suav nws lub ntim, thiab muab nws los ntawm qhov ntom ntawm cov yas (feem ntau qhov ntom ntawm polyethylene yog li ntawm 0.92 g / cm ³) kom tau qhov hnyav ntawm lub hnab yas. Piv txwv li, yog tias qhov loj ntawm lub hnab yas yog 42cm x 18cm thiab thickness yog 0.00007cm, ces nws ntim yog kwv yees li 42 x 18 x 0.00007 cubic centimeters. Multiplying lub ntim los ntawm qhov ntom yields qhov hnyav.
Cov qauv yooj yim rau kev xam qhov hnyav ntawm biodegradable eco-friendly hnab yog:
Nyhav=density x volume
Ntawm lawv:
Qhov ceev (p) feem ntau yog ntsuas hauv grams ib cubic centimeter (g / cm ³) thiab yog qhov piv ntawm qhov loj ntawm cov khoom rau nws ntim.
Volume (V) feem ntau yog ntsuas hauv cubic centimeters (cm ³) thiab tuaj yeem xam raws li qhov loj ntawm lub hnab yas.
Rau biodegradable eco-phooj ywg hnab ua los ntawm cov khoom sib txawv, cov qauv kev suav yog tib yam, tab sis tus nqi ntom ntom ntawm cov khoom sib thooj yuav tsum tau siv. Nov yog ntau qhov sib txawv ntawm cov ntaub ntawv biodegradable thiab cov piv txwv ntawm kev siv cov kev ceev no los xam qhov ntim thiab qhov hnyav:
1. Polyethylene (PE) - nrog qhov ceev ntawm kwv yees li 0.92 g / cm³
2. Polylactic acid (PLA) - nrog qhov ceev ntawm kwv yees li 1.24 g / cm³
3. Polyadipic acid! Polybutylene terephthalate (PBAT) - nrog qhov ceev ntawm kwv yees li 1.19 g / cm³
Piv txwv tias peb muaj lub hnab yas nrog qhov ntev ntawm 42cm hauv qhov ntev, 18cm dav, thiab 0.00007cm hauv tuab, peb tuaj yeem siv cov kauj ruam hauv qab no los xam qhov hnyav ntawm lub hnab yas ua los ntawm cov khoom sib txawv:
1. xam ntim:
V=Length x Dav x Thickness
V = 42 x 18 x 0.00007
2. xam qhov hnyav uas siv qhov ntom ntom:
Luj =px V
Piv txwv li, rau cov hnab yas ua los ntawm cov khoom siv polyethylene:
Qhov hnyav PE {{0}}.92 x (42 x 18 x 0.00007)
Rau cov hnab yas ua los ntawm polylactic acid (PLA) khoom:
Qhov hnyav PLA{{0}}.24 x (42 x 18 x 0.00007)
Rau cov hnab yas ua los ntawm poly (adipic acid / butylene terephthalate) (PBAT) khoom:
Qhov hnyav PBAT{{0}}.19 x (42 x 18 x 0.00007)
Thov nco ntsoov tias nyob rau hauv kev xam tiag tiag, nws yog ib qho tsim nyog los sib sau ua ke qhov loj me hauv centimeters thiab xyuas kom meej tias cov thickness units yog centimeters es tsis yog meters los yog lwm yam units, thiaj li yuav xam qhov ntim kom raug.
Nws yuav tsum tau muab sau tseg tias cov khoom ntawm biodegradable eco-friendly hnab yuav txawv ntawm cov hnab yas zoo tib yam, xws li polylactic acid (PLA) los yog poly (adipic acid / butylene terephthalate) (PBAT), thiab lwm yam. Qhov ceev ntawm cov ntaub ntawv no tej zaum yuav yog. sib txawv ntawm polyethylene, yog li cov nqi sib xws yuav tsum tau siv rau hauv kev suav. Lub caij no, cov yam ntxwv degradation thiab ib puag ncig cuam tshuam ntawm biodegradable eco-friendly hnab kuj tseem ceeb uas yuav tsum tau xav txog thaum xaiv lawv.
