M'chilimwe, dzuwa likamatentha ngati moto, nthawi zambiri limagwa mvula komanso thukuta, ndipo magalasi amakhala pachiwopsezo chachikulu cha kutentha kwambiri komanso kukokoloka kwa mvula. Anthu omwe amavala magalasi amapukuta magalasi pafupipafupi. Kuphulika ndi kusweka kwa magalasi kungachitike chifukwa chogwiritsa ntchito molakwika. Chilimwe ndi nthawi yomwe magalasi amawonongeka mwachangu kwambiri. Kodi mungateteze bwanji chophimba cha magalasi kuti chisawonongeke, ndikuwonjezera nthawi ya moyo wa magalasi?
A. Kupewa kukhudza lenzi ndi khungu
Tiyenera kuyesetsa kuletsa magalasi owonera kuti asakhudze khungu ndikusunga mbali ya mphuno ya chimango cha magalasi ndi m'mphepete mwa lenzi ya magalasi kutali ndi masaya, kuti tichepetse kukhudzana ndi thukuta.
Tiyeneranso kutsuka magalasi athu m'mawa uliwonse tikamatsuka nkhope. Tsukani phulusa loyandama pa magalasi ndi madzi, ndipo tengani madziwo ndi nsalu yotsukira magalasi. Ndikoyenera kugwiritsa ntchito mankhwala ofooka a alkaline kapena osalowerera ndale, m'malo mogwiritsa ntchito mowa wamankhwala.
B. Chimango cha magalasi chiyenera kutsukidwa ndi kusamalidwa bwino
Tikhoza kupita ku shopu yowunikira kapena kugwiritsa ntchito njira yosamalira khungu kuti titsuke makachisi, magalasi, ndi zophimba miyendo. Tingagwiritsenso ntchito zipangizo zamagetsi kuti titsuke magalasi.
Pa chimango cha mbale (chomwe chimadziwika kuti "chimango cha pulasitiki"), chifukwa cha kutentha kwambiri nthawi yachilimwe, chimakhala chopindika mosavuta. Pankhaniyi, muyenera kupita ku shopu yowunikira kuti mukonze pulasitiki. Kuti mupewe kuwonongeka kwa khungu kuchokera ku chimango chakale cha mbale, ndi bwino kuyeretsa chimango chachitsulo ndi mowa wamankhwala milungu iwiri iliyonse.
C. MFUNDO ZA KUSAMALIRA MAGALASI
1. Chotsani magalasi ndi manja onse awiri, gwiritsani ntchito mosamala, ndipo ikani lenzi molunjika mukamayiyika, ndipo isungeni mu chikwama cha lenzi ngati simukufunikira.
2. Ngati chimango cha chiwonetserocho chili cholimba kapena chosasangalatsa kapena chokulungiracho chili chomasuka, tiyenera kusintha chimangocho ku shopu yowunikira.
3. Mukatha kugwiritsa ntchito magalasi tsiku lililonse, pukutani mafuta ndi sweat acid pamphuno ndi chimango nthawi yake.
4. Tiyenera kuyeretsa zodzoladzola ndi zinthu zina zokongoletsera pogwiritsa ntchito mankhwala ochokera ku chimango chifukwa n'zosavuta kuwononga chimangocho.
5. Pewani kuyika magalasi pamalo otentha kwambiri, monga zotenthetsera, galimoto yotsekedwa nthawi yachilimwe, kapena nyumba ya sauna.
Ukadaulo Wophimba Zinthu Zambiri Wopangidwa ndi Universal Optical Hard
Pofuna kuonetsetsa kuti kuwala kukugwira ntchito bwino komanso kuti lenziyo ikhale ndi ma lenzi abwino kwambiri, Universe Optical imagwiritsa ntchito zida zomatira za SCL zochokera kunja. Lenziyo imadutsa m'njira ziwiri monga utoto wa primer ndi utoto wa pamwamba, zomwe zimapangitsa kuti lenziyo ikhale yolimba komanso yolimba, zomwe zimatha kukwaniritsa zofunikira za satifiketi ya US FDA. Pofuna kuwonetsetsa kuti lenziyo ikuyenda bwino, Universe Optical imagwiritsanso ntchito makina omatira a Leybold. Kudzera muukadaulo womatira wa vacuum, lenziyo imakhala ndi kutulutsa kwamphamvu, mphamvu yabwino yotsutsa kuwunikira, kukana kukanda komanso kulimba.
