Ndikutanthauza zoyendetsa, zoseweretsa ana kapena zaku China. Ma Dryer, ma thermos, ma TV, ma routers, ma foni ndi mafoni, ndi zina zambiri. Sitikudziwa kuchuluka kwa zinyalala zomwe timapanga, zonse zomwe timataya ...
Tikufuna kuyankha funso wamba.
Ndingatani ndi ...? Kodi ndingagwiritse ntchito mwayi wanji ...?
Ndasunga kwa nthawi yayitali makina awiri owonongeka apakompyuta a Samtron, popeza sindikudziwa zaka zingati zapitazo. Lingaliro loyamba linali kuyesa kukonza chimodzi ndi ziwalo za chinzake. Koma lero sizimvekanso kukhala ndi chowunikira chamtundu uwu, kotero ndiwagawanitsa ndikusunga magawo omwe ali okondweretsa.
Chinthu choyamba kungotsegula, ndipo musanakhudze chirichonse, ndicho tulutsani flyback kuti isatipatse kutulutsa kwa makumi angapo masauzande a volts. Opaleshoniyo ndi yofanana ndi yomwe timachita kuti titsitse microwave condenser. Timazungulira mozungulira.
Ofufuza kuchokera ku MIT adapanga njira akonzanso mabatire am'galimoto omwe agwiritsidwa ntchito ndikuwagwiritsa ntchito popanga ma solar.
Mpaka pano, 90% yama batri oyendetsa galimoto ku United States amasinthidwa kuti apange mabatire ambiri, koma idzafika nthawi pomwe ukadaulo uwu usinthidwa ndi mitundu ina ya mabatire ndipo ngati sizingatheke / chidwi chobwezeretsanso iwo atha kukhala okhwima vuto lachilengedwe.
Chifukwa chake MIT yapeza yankho labwino kwambiri. Ndi njira yosavuta yomwe imawalola kuti asinthidwenso kuti awasandutse magwiridwe antchito azuwa. Ndipo chabwino ndikuti mbale izi zikamaswa itha kubwerezedwanso m'mabatani atsopano.
Komanso, maubwino samathera pano. njirayi ndi yoipitsa pang'ono poyerekeza ndi yomwe ikugwiritsidwa ntchito pakadali pano kutulutsa mtovu. Chifukwa chake zikuwoneka kuti zonse zili bwino. Ngakhale kuyendetsa bwino kwa mbale zatsopanozi zomwe zili pafupifupi 19% pafupifupi chimodzimodzi pazipita zotheka ndi matekinoloje ena. Tsopano chomwe chikusowa ndi kampani yomwe idadzipereka kutsatsa.
Ngati ndinu m'modzi mwa iwo omwe amadyera yogati mu mphika wagalasi, mosakayikira mwasunga magalasi kuti achite china chake chosazolowereka ndipo pamapeto pake chimakhala mu kabati kapena choipa kwambiri, mu zinyalala.
El Silika gel osakaniza Amagwiritsidwa ntchito ngati wothandizira kuti athetse chinyezi cha mpanda. Kutentha kwake kwakukulu kumapangitsa kukhala chinyezi chabwino. Monga momwe muwonera ngakhale pali zokambirana za Silika gel osakaniza, iyi si gel osakaniza, koma yolimba.
Matumbawa amapezeka tikamagula nsapato, zovala, ndi zinthu zina zambiri. Ndipo nthawi zambiri sitikudziwa choti tichite nawo ndipo amathera ku zinyalala.
Zofunika:
Silika gel osakaniza lili cobalt mankhwala enaake, amene, polimbana ndi chinyezi, kutembenukira ku buluu kuti pinki. Fumbi lomwe limapangidwa mukamagwiritsa ntchito mankhwalawa limatha kuyambitsa silicosis, chifukwa chake musaliphwanye kapena zina.
El polystyrene yotulutsa (XPS), yomwe imagulitsidwa pansi pa dzina la Stryrofoam, amapangidwa ndi 95% polystyrene ndi 5% mpweya womwe watsekedwa munthawi ya extrusion.
Kupangidwa kwa mankhwala a polystyrene yotulutsidwa ndi ofanana ndi wa polystyrene yowonjezera. Koma njira yakapangidwe ka Styrofoam, Amapereka kutentha kwambiri ndipo amachititsa kuti madzi asamavutike.
Ngati simukudziwa kuti polystyrene ndi chiyani, ndi chomera, choyera chamoyo chonse, ndi chithu, ndi omwe mumaona kuti nthawi zina ndi okhwima. Ndi thovu lomwe timawona kuti amagwiritsa ntchito pomangira nyumba
