Ukukhetha imibhobho zangaphandle

Ngaphandle ezikumgangatho ophezulu indle ukunika inqanaba ngokwaneleyo intuthuzelo, ikhaya mihla nje ngqiqweni. Kodwa ukuba wonge imali kulwakhiwo layo, iye yanika ngokwayo nge nikukwanda lonke iingxaki, ukuze zonke izinto kwinkqubo yokukhupha amanzi kufuneka zibe ekumgangatho obhetele.

ngokukhethekileyo kufuneka zikhethwe ngaphandle imibhobho amdaka. Ngethamsanqa, ushishino mihla inganikeza isixa omkhulu ophezulu ezisemgangathweni nezinto zokufunda ixesha elide, kangangokuba akukho nzima kangaka.

Xa ilindle ezinkulu iinkqubo umbhobho ingasetyenziswa ukusuka asbestos isamente, ufakelo lwesamente, intsimbi uphoswe okanye iiplastiki. Noko ke, musa okunene ukuhlangabezana kutshanje imibhobho ezenziwe asbestos zesamente okanye intsimbi ekutyhidweni, ngokuba malini akathethi masihambelane yokusebenza. Ukongeza, imibhobho yangaphandle mva polymeric ikuyo kulula kakhulu ukuba ukugcina noku faka.

Ngokukodwa, owayesakuba uyathandwa kutshanje, imibhobho ezenziwe etyhidiweyo imfumba neengxaki ezinzulu. Eyona obonakalayo lo nokumelana amahlwempu. Kukholelwa ukuba ngonyaka nje omnye, umbhobho sentsimbi standard iba sokurhuqa yi millimitha ubuncinane enye. Ukuba uthathe ingqalelo thina imiphumo ngqwabalala imisinga uqhuzu kunye neempawu umhlaba kwezinye iindawo ubomi izinto ezinjalo ayikho kwiminyaka engaphezu kwemihlanu okanye ezintandathu. Le umbhobho amdaka (lwangaphandle) nje kuphela imali eninzi, kodwa kwakhona oku sisizathu ixabiso layo eliphezulu.

Kwaye ngoko xa ukhetha umbandela ifanelekileyo kufuneka athathe ingqalelo iparameters ezininzi ezibalulekileyo:

• iimpawu amandla;
• kwalo;
• ukukwazi kukunyamezela utyhileko bume yemichiza banqande;
• ukuxhathisa kugqithise lobushushu.

Cinga ezo imibhobho yelindle ngaphandle kakhulu ukuhlangabezana nazo zonke ezi mfuno zilapha ngasentla.

asbestos imihlobo

Ezi imibhobho ayisindi kwaye luhlala ezenziwe ePortland isamente kwakunye ne-asbestos. Ngenxa olugudileyo kumphezulu ongaphakathi; abayi kucocwe rhoqo kakhulu. Ngelishwa, abaphumeleli ephawulekayo a ubu linyuke kancinane, ngoko ke ukusebenza kunye nemibhobho ezifana abaludingayo ngononophelo kangangoko kunokwenzeka.

uhle polymeric

Ezi imibhobho yangaphandle ngokuqhelekileyo kusetyenziswa kwiminyaka yakutshanje. La elide kakhulu, ziye ubunzima phantsi, kulula ukufaka yaye kwakungekho lula ukuba odla. Esi sithintelo kukuba ngenxa ufakelo lazo kudla kuyimfuneko ukuba kusetyenziswe oomatshini iwelding ezizodwa ezifuna umbane kwi izakhiwo eziphantsi kolwakhiwo. Noko ke, unike ixabiso yabo kunye nokusebenza phezulu, aba "Izitenxo" kungaba lula ukwamkela.

Imibhobho iron Cast

Enoba ezilungileyo izinto polymeric, kodwa amandla abo koomatshini nokuzabalazela amaqondo aphezulu kolusizana. intsimbi waphosa ibe ukuthembeka eliphezulu njalo, kwakunye enokumelana okuhle bume ze yemichiza ndlongondlongo. ukuswela balo ubunzima, ngokunjalo ngokunxulumene xaka.

Ngoko ke, lo umbhobho wamanzi amdaka ngaphandle (ixabiso apho kuxhomekeke kudidi kunye umenzi), kufuneka ukhethe ngobulumko, ugxininise kwiimfuno zabo.
