Magalasi ang'onoang'ono a China ogulitsa - Magalasi ang'onoang'ono opanda kanthu odzaza utoto - Kehui

Ma microspheres agalasi opanda kanthu ndi ma microspheres agalasi okhala ndi kukhuthala kochepa, kulemera kopepuka komanso mphamvu zambiri. Chifukwa cha mawonekedwe ake opanda kanthu, poyerekeza ndi mikanda yagalasi wamba, ili ndi mawonekedwe a kulemera kopepuka, kukhuthala kochepa komanso magwiridwe antchito abwino oteteza kutentha. Njirayi imawonjezedwa mwachindunji ku dongosolo lophimba, kotero kuti filimu yophimba yomwe imapangidwa ndi kuphimba kwa chophimbacho imakhala ndi mphamvu zoteteza kutentha. Kuphatikiza pa kuyamwa mafuta pang'ono komanso kukhuthala kochepa, kuwonjezera 5% (wt) kumatha kuwonjezera chinthu chomalizidwa ndi 25% mpaka 35%, motero sikuwonjezera kapena kuchepetsa mtengo wa unit voliyumu ya chophimbacho.
Magalasi ozungulira opanda kanthu ndi mabwalo otsekedwa opanda kanthu, omwe amawonjezeredwa mu pulasitiki kuti apange mabowo ambiri odziyimira pawokha a kutentha, motero amawongolera kwambiri kutetezedwa kwa filimu yophimba ku kutentha ndi phokoso komanso kuchita gawo labwino pakuteteza kutentha ndi kuchepetsa phokoso. Pangani pulasitiki kukhala yosalowa madzi, yoletsa kuipitsa komanso yoletsa dzimbiri. Pamwamba pa pulasitiki yozungulira yopanda mankhwala imakhala yolimba ku dzimbiri la mankhwala. Filimu ikapangidwa, tinthu ta mikanda yaying'ono yagalasi Zili pafupi kwambiri kuti zikhale ndi ma porosity ochepa, kotero kuti pamwamba pake pamapanga filimu yoteteza yomwe imaletsa chinyezi ndi ma ayoni owononga, zomwe zimathandiza kwambiri pakuteteza.

Kapangidwe kake kozungulira ka mikanda yagalasi yopanda kanthu kamapangitsa kuti ikhale ndi mphamvu yabwino yofalikira pa mphamvu ya kugwedezeka ndi kupsinjika. Kuiyika pa chophimbacho kungathandize kukana kugwedezeka kwa filimu yophimbacho komanso kungachepetsenso kufalikira ndi kupindika kwa kutentha kwa chophimbacho.

Kuyeretsa bwino ndi kufinya. Ufa woyera uli ndi kuyeretsa bwino kuposa utoto wamba, zomwe zimachepetsa kuchuluka kwa zodzaza ndi utoto zina zodula (poyerekeza ndi titanium dioxide, mtengo wa mikanda yaying'ono ndi 1/5 yokha). Zimathandizira kumatirira bwino kwa utoto. Makhalidwe otsika a mikanda yaying'ono yagalasi amalola utomoni wambiri kutenga nawo mbali popanga filimu, motero zimawonjezera kumatira kwa utoto ndi nthawi zitatu mpaka zinayi.

Kuonjezera 5% ya mikanda yaying'ono kungapangitse kuti kukhuthala kwa chophimbacho kukhale kochepa kuchoka pa 1.30 kufika pansi pa 1.0, motero kuchepetsa kwambiri kulemera kwa chophimbacho ndikupewa kuchotsedwa kwa chophimba cha khoma.

Ma microbeads ali ndi mphamvu yabwino yowunikira kuwala kwa ultraviolet, zomwe zimathandiza kuti utotowo usasinthe kukhala wachikasu komanso wokalamba.

Kusungunuka kwakukulu kwa tinthu tating'ono ...

Malangizo ogwiritsira ntchito: Kuchuluka kwa zowonjezera ndi 10% ya kulemera konse. Mikanda yaying'ono imakonzedwa pamwamba ndipo imakhala ndi kachulukidwe kochepa, zomwe zimapangitsa kuti chophimbacho chiwonjezeke ndikuyandama panthawi yosungira. Tikukulimbikitsani kuwonjezera kukhuthala koyambirira kwa chophimbacho (powonjezera kuchuluka kwa chokhuthala kumalamulira kukhuthala kopitilira 140KU), pankhaniyi, chochitika choyandama sichidzachitika chifukwa kukhuthala kuli kotsika kwambiri, ndipo tinthu tating'onoting'ono ta chinthu chilichonse m'dongosolo timachepa chifukwa cha kukhuthala kwakukulu, komwe kumathandiza kuwongolera kukhazikika kwa kukhuthala. Tikukulimbikitsani kwambiri njira yotsatirayi yowonjezera: chifukwa mikanda yaying'ono ili ndi makoma owonda a tinthu tating'onoting'ono komanso kukana kudulidwa kochepa, kuti mugwiritse ntchito bwino mawonekedwe a mikanda yaying'ono, tikukulimbikitsani kugwiritsa ntchito njira yomaliza yowonjezera, kutanthauza kuti, ikani mikanda yaying'ono kumapeto kwa Kuwonjezerako kumafalikira ndi zida zosakaniza ndi liwiro lotsika komanso mphamvu yochepetsedwa yodulidwa momwe mungathere. Chifukwa mawonekedwe ozungulira a mikanda yaying'ono ali ndi kusinthasintha kwabwino ndipo kukangana pakati pawo si kwakukulu, ndikosavuta kufalikira. Ikhoza kunyowetsedwa kwathunthu munthawi yochepa, ingowonjezerani nthawi yosakaniza kuti ifike pofalikira mofanana.

Tizilombo toyambitsa matenda timakhala topanda mankhwala ndipo sitili ndi poizoni. Komabe, chifukwa cha kulemera kwake kopepuka kwambiri, chisamaliro chapadera chikufunika powonjezera. Tikupangira njira yowonjezera pang'onopang'ono, ndiko kuti, kuchuluka kwa chowonjezera chilichonse ndi theka la tizilombo toyambitsa matenda totsala, ndipo pang'onopang'ono timawonjezeredwa, zomwe zingalepheretse kuti tizilombo toyambitsa matenda tisamayende mumlengalenga ndikupangitsa kuti kufalikira kwake kukhale kokwanira.
