Ubwino wa nsalu zosalukidwa kodi mukudziwa kuchuluka kwake | JINHAOCHENG

Chogulitsacho chapangidwa ndinsalu yosalukidwaNdi mbadwo watsopano wa zipangizo zosamalira chilengedwe. Sizimatha kunyowa, zimapuma, zimasinthasintha, zimakhala zopepuka, sizimayaka, zimawonongeka mosavuta, sizimawononga komanso sizimakwiyitsa, zimakhala ndi utoto wambiri, zimakhala ndi mtengo wotsika komanso zimatha kubwezeretsedwanso.

Zinthuzo zimatha kuwola mwachilengedwe zitayikidwa panja kwa masiku 90. Zimakhala ndi moyo wautali wa zaka 5. Sizili ndi poizoni, sizinunkha ndipo zilibe zinthu zotsalira zikawotchedwa, kotero sizimaipitsa chilengedwe ndipo zimadziwika padziko lonse lapansi ngati chinthu choteteza chilengedwe chomwe chimateteza chilengedwe cha dziko lapansi.

Ubwino:

1. Kulemera kopepuka: Utomoni wa polypropylene ndiye chinthu chachikulu chopangira. Mphamvu yake yeniyeni ndi 0.9 yokha, magawo atatu mwa asanu okha a thonje, lomwe ndi lofewa komanso lomveka bwino.

2. Chopanda poizoni, chosakwiyitsa: Chogulitsachi chimapangidwa motsatira malamulo a FDA pankhani ya chakudya, chilibe mankhwala ena, chimagwira ntchito bwino, sichimayambitsa poizoni, sichimanunkhira bwino, ndipo sichimakwiyitsa khungu.

3. Mankhwala oletsa mabakiteriya ndi mankhwala oletsa mabakiteriya: Polypropylene ndi chinthu chopanda mankhwala, chomwe sichimapweteka, ndipo chimatha kusiyanitsa mabakiteriya ndi tizilombo tomwe tili mumadzi. Mankhwala oletsa mabakiteriya, dzimbiri la alkali, ndi zinthu zomalizidwa sizimakhudza mphamvu zomwe zimadza chifukwa cha kukokoloka kwa nthaka.

4. Makhalidwe abwino a thupi: Amapangidwa pozungulira polypropylene mwachindunji kukhala netiweki, ndipo mphamvu ya chinthucho ndi yabwino kuposa ya zinthu wamba za ulusi wamba, mphamvu yake siili yolunjika, ndipo mphamvu zake zazitali komanso zopingasa ndizofanana.

5. Ponena za kuteteza chilengedwe, nsalu zambiri zopanda ulusi zomwe zimagwiritsidwa ntchito ndi polypropylene, ndipo zinthu zopangira matumba apulasitiki ndi polyethylene. Ngakhale kuti zinthu ziwirizi zili ndi mayina ofanana, zili ndi kapangidwe ka mankhwala kosiyana kwambiri. Kapangidwe ka molekyulu ya mankhwala ya polyethylene kali ndi kukhazikika kwakukulu ndipo n'kovuta kwambiri kuwonongeka. Chifukwa chake, zimatenga zaka 300 kuti thumba la pulasitiki liwonongeke. Kapangidwe ka mankhwala ka polypropylene sikolimba, ndipo unyolo wa molekyulu ukhoza kusweka mosavuta, kotero kuti ukhoza kuwonongeka bwino. Ndipo mu mawonekedwe osaopsa mu kuzungulira kwina kwa chilengedwe, achikwama chogulira zinthu chosalukidwaikhoza kuwola kwathunthu mkati mwa masiku 90. Kuphatikiza apo, thumba logulira losalukidwa likhoza kugwiritsidwanso ntchito nthawi zoposa 10, ndipo kuchuluka kwa kuipitsidwa kwa chilengedwe pambuyo potaya ndi 10% yokha ya thumba la pulasitiki.
