Mitundu ya polyurethane

Tsiku ndi tsiku, zojambula zamakono zimadabwitsa ife ndi malingaliro atsopano. Chimodzi mwazo ndizo kugwiritsa ntchito zipangizo za polyurethane zolowa padenga. Nkhaniyi ndi yamphamvu kwambiri ndipo imakulolani kuti mubise zolakwika zambiri pamtunda.

Kuwonjezera pamenepo, kusintha kosinthika kuchokera ku denga kupita ku khoma kungasinthe ndikusintha maonekedwe a chipinda mwa njira yachilendo.

Aliyense amadziwa kuti kuunikira mu chipinda kumaseŵera mbali yofunikira kwambiri popanga chikhalidwe chofanana ndi chisokonezo, ndipo chitukuko chake chiyenera kuchitidwa mwatcheru. Choncho, ojambula apanga mapangidwe apadera a polyurethane omwe akuphimba chipinda, chomwe chingasinthe mkati mwawo. Njirayi ikuwoneka yodabwitsa kwambiri, imakulolani kuti muwoneke mowonjezera malo ochepa mu chipindamo ndipo pang'ono "kwezani" zotchinga ndipo zingakhale zokometsetsa kwambiri pazinthu zamakono zamakono. Tidzakudziwitsani zambiri zokhudza zokongoletsa ndi kuyika zinthu izi zokongoletsera m'nkhani yathu.

Mpukutu wa polyurethane ndodo ya mabala a LED

Msika wamakono umatipatsa kusankha kwakukulu kotere. Mapepala osasangalatsa ndi oyenerera mazenera oletsedwa omwe safuna maonekedwe okhwima ndi okonzeka. Ndipo m'malo mwake, chimanga cha polyurethane mkati mwake ndi chithunzi chovomerezeka chidzaphatikiza chithunzi chonse pamodzi ndi mafano ake opatsa mpumulo ngati mawonekedwe, masamba, maluwa, zokongoletsera, zojambulidwa kapena zojambulajambula.

Kukondweretsa kokondweretsa ndikuti kukwera phala la polyurethane ndodo ya mabala a LED ndi losavuta. Zonsezi zimatenga pafupifupi theka la tsiku, ndipo nthawi zambiri zimatulutsa khungu. Choyamba, chimanga chimamangirizidwa pakhomalo, kenaka mkati mwake chiyenera kuyendetsedwa ndi tepi yojambula, kuti tipewe moto ngati kutsekedwa. Mbali zina za tepi ya LED zimagulitsidwa pamalumikizidwe ndikutsekedwa ndi tepi yamagetsi. Kenaka, motsatira malangizo, gwiritsani makina onse ofunikira, chotsani filimuyi ndi kumangiriza tepiyo mwachindunji mkati mwa mafunde. Mukatsegula, kuwala kumeneku kukufalikira mofanana kuzungulira chipindacho, ndipo gwero lake silidzapindula kwambiri.

Popeza kuwala kwa LED sikuchotsa kutentha ndi kupindulitsa molimbika kumapeto kwa denga, chophimba chotchedwa polyurethane ndodo ya mipiringidzo ya LED chingagwiritsidwe ntchito bwino poyatsa denga lotambasula.
