Kukhalapo kwa kuipitsa phukusi kumadalira zida zawo ndikugwiritsa ntchito. Nthawi zina, ngati zinthu zopangidwa kapena zopangidwa ndi chivundikiro cha pack ya ayezi sizikumana ndi miyezo yachitetezo cha chakudya, zitha kukhala zenizeni kuipitsidwa. Nayi malingaliro akuluakulu:
1. Mankhwala Osiyanasiyana:
-Matumba otsika otsika amatha kukhala ndi mankhwala oyipa monga Benzene ndi Phtates (popukusira), yomwe ingawononge vuto laumoyo. Mankhwala awa amatha kufinya chakudya panthawi yogwiritsa ntchito, makamaka mu kutentha kwambiri.
2. Zowonongeka ndi Kutayika:
-Titi chikwama cha ice chimawonongeka kapena chomata mukamagwiritsa ntchito, gel kapena madzi mkatimo amatha kulumikizana ndi chakudya kapena zakumwa. Ngakhale mafilimu ambiri a ayezi ndi oundana (monga polymer gel kapena yankho la saline), kulumikizana mwachindunji sikukulimbikitsidwa.
3. Chitsimikizo cha Zogulitsa:
-Pasankha pa paketi ya Ice, yang'anani chiphaso cha chakudya, monga kuvomerezedwa ndi FDA. Zolemba izi zikuwonetsa kuti zinthu za papaketi ya madzi oundana ndizotetezeka komanso zoyenera kulumikizana ndi chakudya.
4. Kugwiritsa ntchito molondola ndi kusungirako:
-Kukhondo kwa mapaketi a ice musanagwiritse ntchito, ndikuwasunga bwino. Pewani kuyanjana ndi zinthu zakuthwa kuti mupewe kuwonongeka.
-Pakuti pogwiritsa ntchito paketi ya madzi, ndibwino kuti muikemo chikwama cha madzi kapena kukulunga ndi thaulo kuti musacheze mwachindunji ndi chakudya.
5. Nkhani Zachilengedwe:
-Kuteteza zachilengedwe, mapaketi oundana amatha kusankhidwa, ndipo amafunikira kulandila njira zobwezeretsedwa ndi kutayidwa kwa njira zounitsira ma utoto kuti muchepetse kuwonongeka kwa chilengedwe.
Mwachidule. Ngati pali nkhawa zapadera, mutha kumvetsetsa mwatsatanetsatane zida zamalonda ndi kuwunika kwa ogwiritsa ntchito musanagule.
Zigawo zikuluzikulu za mafinya oundana
Mapaketi a madzi oundana amakonzedwa nthawi zambiri amapangidwa ndi zinthu zingapo zofunika popereka kuperekera zinthu zabwino komanso kukhazikika kokwanira. Zida zazikulu zimaphatikizapo:
1. Zosanjikiza kunja:
-Nzake: zopepuka komanso zolimba, zomwe nthawi zambiri zimagwiritsidwa ntchito poyang'ana kunja kwa mapaketi apamwamba kwambiri. Nylon ali ndi vuto kukana ndi kusokoneza misozi.
-Oyenetse: winanso yemwe amagwiritsa ntchito zinthu zakunja, zotsika mtengo kuposa namloni, komanso zimakhalanso ndi kukhazikika kwam'misona.
-VIYL: yoyenera kugwiritsa ntchito mapulogalamu omwe amafunikira madzi osasunthika kapena osavuta kuyeretsa malo.
2. Zinthu zotsikira:
-Polwirethane chithovu: Ndi zinthu zofala kwambiri, ndipo zimagwiritsidwa ntchito kwambiri mu madzi oundana oundana chifukwa cha magwiridwe antchito abwino kwambiri.
-Polystyrene (eps) chithovu: omwe amadziwikanso kuti Strrofoam, nkhaniyi imagwiritsidwa ntchito mabokosi ozizira kwambiri komanso njira zina zosungira nthawi imodzi.
3. Zamkati zovala zamkati:
-Avulmunum zojambulajambula kapena filimu yachitsulo: yomwe nthawi zambiri imagwiritsidwa ntchito ngati zinthu zomwe zimathandizira kuwonetsa kutentha ndikukhalabe kutentha kwamkati.
-Fod kalasi ya peva (polyethylene vinyl acetate): Zinthu zopanda pake zomwe zimagwiritsidwa ntchito poizoni mkati mwa chakudya, ndipo mulibe PVC.
4. Filler:
-Geli thumba: thumba lomwe lili ndi gel yosalala, yomwe imatha kupitilirabe kuzizira kwa nthawi yayitali mutazizira. Gel nthawi zambiri imapangidwa ndi kusakaniza madzi ndi polymer (monga polyacryamide), nthawi zina zoteteza ndi antifalapy ndi zipewa zimawonjezeredwa kuti zizigwira ntchito.
-Madzi ena kapena mayankho ena: Mapaketi ena osavuta okha amatha kukhala ndi madzi amchere okha, omwe ali ndi nthawi yotsika kuposa madzi oyera ndipo amatha kupatsa nthawi yayitali yozizira panthawi ya firiji.
Mukamasankha thumba loyenerera loyenera, muyenera kuganizira ngati zida zake zikukwaniritsa zosowa zanu zenizeni, makamaka ngati chitetezero cha chakudya chimafunikira kuyeretsa kapena kugwiritsa ntchito malo ena.
Zigawo zazikuluzikulu za ma utoto oundana
Phukusi lachisanu limakhala ndi zigawo zingapo zotsatirazi, iliyonse yomwe ili ndi ntchito zina kuti muwonetsetse kuti chisanu cha oundana chimakhala ndi kutentha kochepa:
1. Zosanjikiza kunja:
-Nnylon: Nylon ndi chokhacho, chopanda madzi, komanso zopepuka zopepuka zokhala ndi matumba oundana omwe amafunikira kuyenda kwa ayezi komwe kumafuna kuyenda pafupipafupi kapena kugwiritsa ntchito zakunja.
-Oyerter: Polyester ndi zina zambiri zokhazikika zomwe zimagwiritsidwa ntchito pachigoba chakunja kwa matumba oundana, ndikulimbana ndi kukana.
2. Kusanjikiza:
-Polwirethane chithovu: Ndi zinthu zothandiza kwambiri, ndipo zimagwiritsidwa ntchito kwambiri m'matumba oundana chifukwa cha kuthekera kosinthasintha kotentha.
-Polystyrene (eps) chithovu: omwe amadziwikanso kuti styrene chithovu, zopepukazi zimagwiritsidwanso ntchito mu firiri ndi zophika, makamaka mayankho firiji.
3. Chingwe chamkati:
-Avuldum zojambulajambula kapena filimu yokhazikika: Zipangizozi zimagwiritsidwa ntchito ngati zingwe zothandizira kusintha mphamvu kutentha ndikuwonjezera zovuta.
-Fod kalasi ya Peva: Ichi ndi chinthu chosafunikira cha pulasitiki chomwe chimagwiritsidwa ntchito polowera mkati mwa ma utoto a ayezi, ndikuonetsetsa kuti kulumikizana ndi chakudya.
4. Filler:
-Geli: Zogwiritsidwa ntchito kawirikawiri za matumba oundana ndi gel, zomwe nthawi zambiri zimakhala ndi madzi, ma polymers (monga polyacryammide) ndi zowonjezera zazing'onoting'ono (monga antifalapts). Mafuta awa amatha kuyamwa kutentha kwambiri ndikumasula pang'onopang'ono kuzizira pambuyo pozizira.
-Salt Madzi am'madzi: Mapaketi ena osavuta a Ice, madzi amchere akhoza kugwiritsidwa ntchito ngati ozizira chifukwa madzi amchere amatsika kuposa madzi oyera, kupereka kuzizira kwambiri.
Posankha mapaketi ozizira, ndikofunikira kuwonetsetsa kuti zinthu zosankhidwa ndi zotetezeka, zachilengedwe, ndipo zitha kukwaniritsa zosowa zanu, monga kusamalira chakudya. Pakadali pano, lingalirani kukula ndi mawonekedwe a ma utoto oundana kuti awonetsetse kuti ali ndi chidebe chanu kapena malo osungira.
