Chifukwa chiyani mitengo ya zinthu zitatu ikukwera?

Tisanayankhe funso ili, choyamba timvetsetse kuti tritan ndi chiyani?

Tritan ndi copolyester yopangidwa ndi American Eastman Company ndipo ndi imodzi mwazinthu zamapulasitiki zamakono. M'mawu a layman, nkhaniyi ndi yosiyana ndi zipangizo zomwe zilipo pamsika chifukwa ndi zotetezeka, zowononga zachilengedwe, komanso zowonjezereka. Mwachitsanzo, makapu amadzi apulasitiki opangidwa ndi zinthu za PC sayenera kukhala ndi madzi otentha. Kutentha kwa madzi kukadutsa madigiri 70 Celsius, zinthu za PC zidzatulutsa bisphenolamine, yomwe ndi BPA. Ngati imakhudzidwa ndi BPA kwa nthawi yayitali, imayambitsa kusokonezeka kwamkati m'thupi la munthu ndipo imakhudza kubereka. System thanzi, kotero miyambo pulasitiki madzi makapu akuimiridwa ndi PC sangathe kugwiritsidwa ntchito ndi ana, makamaka makanda. Tritan satero. Nthawi yomweyo, imakhala ndi kulimba bwino komanso kulimbikira kukana. Choncho, Tritan nthawi ina ankanenedwa kuti ndi pulasitiki yopangidwa ndi ana. Koma nchifukwa ninji mitengo ya zinthu za tritan ikukwera?

Pambuyo pophunzira za Tritan, sikovuta kupeza kuti m’chitaganya chamakono, anthu amasamalira kwambiri mkhalidwe wa moyo ndi thanzi. Nthawi yomweyo, mafakitale opanga ndi ogulitsa malonda akulimbikitsa mwamphamvu kugwiritsa ntchito zinthu zotetezeka komanso zathanzi za Tritan. Kuphatikiza mfundo ziwirizi, sikovuta kuona kuti chifukwa chachikulu chakukwera kwa mtengo wa Tritan ndikuwongolera mphamvu zopanga. Pamene kufunikira kwa msika kukuchulukirachulukira ndipo kupanga kukucheperachepera, mitengo yazinthu idzakwera mwachibadwa.

Komabe, chifukwa chenicheni chakukwera kwamitengo yazinthu ndi nkhondo yaku US yolimbana ndi msika waku China. Kuwonjezeka kwamtengo pansi pa maziko apadera sizinthu zaumunthu zokha, komanso kuwonjezereka kwa mphamvu zachuma. Chifukwa chake, popanda kuthetsa zifukwa ziwiri zomwe zili pamwambazi, ndizovuta kuti zida za Tritan zipeze malo ochepetsera mitengo. Amalonda ena ndi opanga amafunika kusunga zinthu zambiri kuphatikiza pakugwiritsa ntchito ndi kungoyerekeza. Tilinso tcheru ndi izi ndipo sitingaletse mwayi wodula leeks ku United States.
