Kuyamba kwa Zakudya Zina Zapulasitiki

Kufufuza kwa Chidziwitso cha Zaumoyo cha PP, PC, PS, Botolo la Madzi a Tritan Pulasitiki

Mabotolo amadzi apulasitiki amatha kuwonekera kulikonse m'moyo. Mabotolo amadzi apulasitiki ndi olimba kugwa, osavuta kunyamula, komanso owoneka bwino, anthu ambiri amakonda kusankha mabotolo amadzi apulasitiki akagula mabotolo amadzi. M'malo mwake, anthu ambiri sadziwa zomwe zimapangidwa ndimabotolo amadzi apulasitiki, ndipo nthawi zambiri samvera masanjidwe ndi chitetezo cha zinthu zamabotolo amadzi, ndipo nthawi zambiri samanyalanyaza chitetezo chamabotolo amadzi.

Zipangizo wamba zamabotolo amadzi apulasitiki ndi Tritan, PP pulasitiki, PC pulasitiki, PS pulasitiki. PC ndi polycarbonate, PP ndi polypropylene, PS ndi polystyrene, ndipo Tritan ndi m'badwo watsopano wazinthu zopangidwa ndi copolyester.

PP ndi chimodzi mwazida zotetezeka kwambiri pakadali pano. Imatha kupirira kutentha kwambiri ndipo imatha kutenthedwa mu uvuni wa microwave. Ili ndi kutentha kwambiri, koma siyolimba, kosavuta kuthyola, ndipo imakhala yowonekera pang'ono.

Zida za PC zili ndi bisphenol A, yomwe imasulidwa ikamawotha kutentha. Kudya kwakanthawi kochepa kwa bisphenol A kumawononga thanzi la munthu. Mayiko ndi madera ena aletsa PC kapena kuletsa PC.

PS zakuthupi ndizowonekera bwino kwambiri komanso pamwamba pamtunda. Ndizosavuta kusindikiza, ndipo zimatha kujambulidwa momasuka, ndilopanda fungo, lopanda pake, lopanda poizoni, ndipo sizimayambitsa bowa. Chifukwa chake yakhala imodzi mwazinthu zotchuka kwambiri za pulasitiki.

Opanga akukumana ndi mavuto azaumoyo komanso kuteteza zachilengedwe ndipo akuyang'ana zida zomwe zingalowe m'malo mwa PC.

Pamsika uwu, Eastman waku United States adapanga m'badwo watsopano wa copolyester Tritan. Ubwino wake ndi chiyani?

1. Kukhazikika kwabwino, kuwala pang'ono> 90%, chiutsi <1%, ndi kunyezimira kokhala ngati kristalo, kotero botolo la Tritan limakhala lowonekera bwino komanso lowoneka ngati galasi.

2. Ponena za kukana kwamankhwala, zinthu za Tritan zimakhala ndi mwayi wambiri, chifukwa chake mabotolo a Tritan amatha kutsukidwa ndi mankhwala ophera tizilombo toyambitsa matenda osiyanasiyana, ndipo sawopa kutupa.

3. Mulibe zinthu zovulaza ndipo zimakwaniritsa zofunikira zachitetezo cha chilengedwe ndi thanzi; kulimba kwabwino, mphamvu yayikulu; Kutentha kwakukulu pakati pa 94 ​​℃ -109 ℃.
