Yeyiphi imiba ekufuneka iqwalaselwe xa uthenga iskena somnwe?

Zintathu izinto eziphambili zeskena somnwe kwintengiso: iplastiki, i-zinc, i-zinc, kunye nentsimbi engenasibala. Ngokubanzi, intsimbi engenazibala ngokuqinisekileyo yeyona nto iqinileyo, ilandelwa ngu-zinc alloy, kwaye eyona imbi yeplastiki, engaqhelekanga, okanye i-firemion, okanye i-firemion, okanye i-firemion, okanye yokuqhuma komlilo.

Xa sithenga iskena somnwe wendlu, kufuneka sivavanye ubunzima bokungenisa iminwe yeminwe kunye nokuchaneka kokuthathwa. Ukuba umnwe awunakubonwa emva kokurekhodwa amaxesha amaninzi, inokugwetywa ukuba isisombululo setshixa yeminwe iphantsi kakhulu.

Xa uthenga isitshixo seminwe, ukongeza ekujongeni kwi-lock quidi, ifrint ikwayinxalenye ephambili. Xa uthenga isitshixo somnyango, kuya kufuneka ugxile ekunxibelelaneni nenkonzo yabathengi malunga nezinto ezibonakalayo, i-lock viction, kunye nomsebenzi wokufakelwa ngokuthelekisa.

Umgangatho weskena somnwe yinxalenye enye, kwaye inkonzo yasemva kwentengiso iza nayo iphambili ekufuneka siqwalasele; Khawufane ucinge ukuba inqanawa yecango yaphukile kwaye inkonzo yasemva kwentengiso icotha ukuya emnyango wokulungisa, ukuba amava amabi amava. Ke ngoko, xa uthenga isitshixo somnyango, kufuneka usebenze ngophando oluninzi kwinkonzo yokufaka emva kwentengiso, nokuba kukho iingcali zokubonelela ngeenkonzo, kunye nokusebenza kakuhle kwentengiso emva kwentengiso.
