Kusankha Pakati pa Bokosi Lotetezedwa ndi EPS ndi Bokosi Lotetezedwa ndi PU la Ice Chest Cooler Yanu

Pankhani yosankha yoyenerabokosi loziziritsira la pachifuwa choziziraPaulendo wanu wakunja kapena zosowa zanu za tsiku ndi tsiku zamasana, kumvetsetsa zipangizo zotetezera kutentha n'kofunika kwambiri. Njira ziwiri zodziwika bwino ndi mabokosi oteteza kutentha a EPS (Expanded Polystyrene) ndi mabokosi oteteza kutentha a PU (Polyurethane). Bokosi lililonse lili ndi ubwino wake wapadera, ndipo kudziwa izi kungakuthandizeni kupanga chisankho chodziwa bwino.

Mabokosi Otetezedwa a EPS
Mabokosi otetezedwa ndi EPS amadziwika kuti ndi opepuka komanso otsika mtengo. Amapangidwa ndi mikanda yowonjezera ya polystyrene, yomwe imapereka chitetezo chabwino kuti chakudya ndi zakumwa zanu zizikhala zozizira. Ngati mukufunabokosi la chakudya chamasana lomwe limasunga chakudya choziziraKwa nthawi yochepa, choziziritsira cha EPS chingakhale chokwanira. Komabe, sichingakhale cholimba kwambiri ndipo sichingapirire kugunda kwakukulu, zomwe zimapangitsa kuti chisakhale choyenera kugwiritsidwa ntchito panja molimba.

Mabokosi Otetezedwa a PU
Kumbali inayi, mabokosi otetezedwa a PU amapereka mphamvu yabwino kwambiri yotetezera kutentha. Thovu la polyurethane limapereka R-value yapamwamba, zomwe zikutanthauza kuti limatha kusunga zinthu zanu kuzizira kwa nthawi yayitali. Izi zimapangitsa kuti ma cooler a PU akhale chisankho chabwino paulendo wautali kapena mukafunika kusunga zinthu zowonongeka kwa maola ambiri. Kuphatikiza apo, mabokosi a PU nthawi zambiri amakhala olimba komanso osawonongeka, zomwe zimapangitsa kuti akhale oyenera kuchita zinthu zosiyanasiyana zakunja.

Mapeto
Mukasankha pakati pa bokosi lotetezedwa ndi EPS ndi bokosi lotetezedwa ndi PU la bokosi lanuchoziziritsira cha pachifuwa chozizira chonyamulika, ganizirani zosowa zanu. Ngati mukufuna njira yopepuka komanso yotsika mtengo yoyendera maulendo afupiafupi, choziziritsira cha EPS chingakhale chokwanira. Komabe, paulendo wautali kapena wovuta kwambiri, kuyika ndalama mu bokosi lotetezedwa ndi PU kudzakuthandizani kugwira ntchito bwino komanso kulimba. Pomaliza, chisankho choyenera chidzadalira momwe mukukonzera kugwiritsa ntchito bokosi lanu loziziritsira komanso kuchuluka kwa choziziritsira chomwe mukufuna.
