Mabokosi otsekera nthawi zambiri amagwiritsidwa ntchito kusunga zinthu mkati mwa kutentha kwapadera, kaya ndi kotentha kapena kozizira.Zida zodziwika bwino za bokosi la insulation zikuphatikizapo:
1. Polystyrene (EPS):
Zofunika: Polystyrene, yomwe imadziwika kuti pulasitiki ya thovu, imakhala ndi ntchito yabwino yotchinjiriza komanso mawonekedwe opepuka.Ndi zinthu zotsika mtengo zomwe zimagwiritsidwa ntchito popanga mabokosi otayira kapena osakhalitsa.
Ntchito: Yoyenera kunyamula zinthu zopepuka kapena chakudya, monga nsomba zam'madzi, ayisikilimu, ndi zina.
2. Polyurethane (PU):
Mawonekedwe: Polyurethane ndi thovu lolimba lomwe limagwira ntchito bwino kwambiri komanso mphamvu zamapangidwe.Kutchinjiriza kwake kumakhala bwino kuposa polystyrene, koma mtengo wake ndi wapamwamba.
Kugwiritsa ntchito: Nthawi zambiri amagwiritsidwa ntchito m'mabokosi otsekera omwe amafunikira kutchinjiriza kwa nthawi yayitali kapena amafuna kutsekereza kwamphamvu komanso kolimba, monga kunyamula mankhwala ndi kugawa chakudya chapamwamba.
3. Polypropylene (PP):
Mawonekedwe: Polypropylene ndi pulasitiki yolimba kwambiri yokhala ndi kutentha kwabwino komanso kukana mankhwala.Ndilolemera kuposa polystyrene, koma lingagwiritsidwe ntchito kangapo.
Ntchito: Yoyenera kuti igwiritsidwenso ntchito yotchinjiriza, monga kubweretsa kunyumba kapena malo odyera.
4. Fiberglass:
Mawonekedwe: Mabokosi otchinjiriza a fiberglass ali ndi magwiridwe antchito apamwamba kwambiri komanso olimba.Nthawi zambiri zimakhala zolemera komanso zokwera mtengo, koma zimatha kupereka chitetezo chabwino kwambiri kwa nthawi yayitali.
Ntchito: Yoyenera kunyamula zinthu pansi pazovuta kwambiri, monga zitsanzo za labotale kapena zida zapadera zachipatala.
5. Chitsulo chosapanga dzimbiri:
Mawonekedwe: Mabokosi achitsulo chosapanga dzimbiri amakhala olimba kwambiri komanso magwiridwe antchito abwino kwambiri, pomwe amakhala osavuta kuyeretsa ndi kukonza.Nthawi zambiri zimakhala zolemera komanso zokwera mtengo kuposa zipangizo zapulasitiki.
Kugwiritsa ntchito: Nthawi zambiri amagwiritsidwa ntchito popereka chakudya komanso m'chipatala, makamaka m'malo omwe amafunikira kuyeretsedwa pafupipafupi kapena kupha tizilombo.
Kusankhidwa kwa zinthuzi nthawi zambiri kumadalira zofunikira za kagwiritsidwe ntchito ka bokosi lotsekera, kuphatikizapo kutalika kwa nthawi yotsekera, kulemera kwake, komanso ngati kutetezedwa kwa madzi kapena kukana kukokoloka kwa mankhwala kumafunika.Kusankha zinthu zoyenera kumatha kukulitsa mphamvu yotsekereza poganizira za mtengo wake komanso kulimba.
Kodi pali vuto lililonse loyipitsidwa ndi bokosi lotsekeredwa?
Kaya bokosi lotsekera lidzakhala ndi zovuta zoipitsa makamaka zimatengera zida zake, njira yopangira, ndi njira zogwiritsira ntchito ndi kukonza.Nazi zina zofunika ndi malingaliro owonetsetsa chitetezo mukamagwiritsa ntchito mabokosi otsekedwa:
1. Chitetezo cha zinthu:
-Mabokosi otchinjiriza apamwamba kwambiri amagwiritsa ntchito zinthu zotetezeka komanso zopanda vuto monga pulasitiki ya chakudya, chitsulo chosapanga dzimbiri, kapena aluminiyamu.Onetsetsani kuti bokosi lotsekera lomwe lasankhidwa likugwirizana ndi miyezo yapadziko lonse kapena yadziko lonse yachitetezo cha chakudya, monga FDA (US Food and Drug Administration) kapena miyezo ya EU.
-Mabokosi ena otsekera otsika amatha kugwiritsa ntchito zinthu zomwe zili ndi mankhwala owopsa, monga zitsulo zolemera kapena zopangira mapulasitiki okhala ndi ma phthalates, omwe amatha kusamukira ku chakudya.
2. Njira yopanga:
-Mvetserani ngati njira yopangira mabokosi otsekera ikugwirizana ndi chilengedwe komanso thanzi.Opanga ena amatha kugwiritsa ntchito mankhwala oopsa panthawi yopanga, omwe amatha kukhalabe pazogulitsa.
3. Kugwiritsa ntchito ndi kukonza:
-Bokosi lotsekera likhale loyera.Musanagwiritse ntchito komanso mutatha kugwiritsa ntchito, bokosi lotsekera liyenera kutsukidwa bwino, makamaka m'kati, kuteteza kukula kwa bakiteriya komanso kusamuka kwa mankhwala.
-Yang'anani ngati bokosi lotsekera lili bwino komanso losawonongeka.Mabokosi otsekera owonongeka amatha kusokoneza kukhulupirika kwawo, zomwe zimapangitsa kuti mabakiteriya adziunjikane mosavuta.
4. Pewani kukhudzana mwachindunji ndi chakudya:
-Ngati mukukhudzidwa ndi chitetezo cha zinthu zomwe zili mkati mwa bokosi lotsekedwa, mutha kuyika chakudya m'mitsuko yosindikizidwa kapena matumba apulasitiki amtundu wa chakudya kuti musagwirizane ndi makoma amkati a bokosi lotsekeredwa.
5. Zinthu zachilengedwe:
-Ganizirani kusankha mabokosi otsekera opangidwa ndi zinthu zomwe zingagwiritsidwenso ntchito kuti muchepetse kuwononga chilengedwe.Kuphatikiza apo, kusankha bokosi lotsekera lokhalitsa kumatha kuchepetsa kutulutsa zinyalala.
6. Chizindikiro ndi Chitsimikizo:
-Kusankha mabokosi otchinjiriza kuchokera kuzinthu zodziwika bwino nthawi zambiri kumakhala kotetezeka chifukwa mitunduyi ili ndi udindo wotsatira mfundo zachitetezo.Yang'anani ngati malondawo ali ndi ziphaso zotetezedwa, monga ziphaso zachitetezo chazakudya.
Poganizira zomwe zili pamwambazi, zaumoyo ndi zachilengedwe zomwe zimayambitsidwa ndi kugwiritsa ntchito mabokosi otsekedwa zimatha kuchepetsedwa kwambiri.Kusankha moyenera, kukonza, ndi kugwiritsa ntchito mabokosi otsekeredwa ndikofunikira pakuwonetsetsa kuti chakudya chili chotetezeka.
