Cov Khoom Siv PVA Uas Yaj Tau Dej
Cov ntaub ntawv PVA uas yaj tau hauv dej yog hloov kho los ntawm kev sib xyaw polyvinyl cawv (PVA), hmoov txhuv nplej siabthiab qee yam khoom ntxiv uas yaj tau hauv dej. Cov ntaub ntawv no yog cov khoom siv zoo rau ib puag ncignrog dej solubility thiab biodegradable zog, lawv tuaj yeem yaj tag nrho hauv dejer. Hauv ib puag ncig ntuj, cov kab mob me me thaum kawg rhuav cov khoom ua carbon dioxide thiabdej. Tom qab rov qab mus rau qhov chaw ib puag ncig, lawv tsis muaj tshuaj lom rau cov nroj tsuag thiab tsiaj txhuals.
Qhov kub thiab qhov ceev ntawm cov khoom siv uas yaj tau hauv dej tuaj yeem hloov kho kom tau raws li kev caicov kev cai ntxiv, ntawm no 2108C tuaj yeem yaj hauv dej txias (25 ℃ ± 10 ℃), thiab 2110H tuaj yeemyaj hauv dej kub (> 60 ℃)
Cov yam ntxwv ntawm cov khoom:
1: Kev ceev ceev yaj, qhov kub yaj thiab kev yaj ceev tuaj yeem hloov kho.
2: Nws tuaj yeem raug rhuav tshem thiab ploj mus rau hauv qhov xwm txheej, thiab tuaj yeem ua rau biodegradable tag nrho rau hauv carbon dioxide thiab dej.
3: Cov khoom siv tsis muaj tshuaj lom kiag li: muaj kev nyab xeeb thiab tsis muaj tshuaj lom; tsis muaj kev puas tsuaj rau tib neeg, tsiaj txhu thiab nroj tsuag; nws tuaj yeem sib cuag nrog zaub mov.
4: Cov khoom siv kho tshuab zoo heev, kev ua haujlwm zoo thaum tshav kub kub.
5: Cov khoom siv muaj lub zog tensile siab, kev tiv thaiv zoo, thiab kev ua haujlwm zoo dua ntawm huab cua, uas tiv thaiv kev kis tus kab mob tsis zoo.
Daim Ntawv Thov:
Cov yeeb yaj kiab tsim los ntawm cov ntaub ntawv no tuaj yeem siv los ua cov hnab yuav khoom, cov hnab pov tseg,
cov hnab ntim khoom, cov hnab ntxhua khaub ncaws uas yaj tau hauv dej, thiab lwm yam.
Pob Khoom/Cia:
Lub hnab yas uas tsis ntub dej thiab sab nraud/ntawv-yas uas muaj lub hnab yas nyob hauv
ntim khoom, 25 kg/hnab, ntim kaw rau hauv chav sov, khoom lav rau ob xyoos.
Lus Cim: Cov khoom no muaj qee yam kev nqus dej noo, yog li thov siv lawv sai li sai tau tom qab
qhib lub ntim khoom, lossis kaw cov khoom tsis tau siv nrog cov hnab yas.
