iingenelo ezizodwa zomthi

Okokuqala, iingenelo ezizodwa zokhuni

I-1, iinkuni zinzima kwaye zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala khona.

I-2, ukusebenza kweplanga kuphezulu, ikakhulu ngenxa yezinto zokhuni zilula, zithambile, ukusetyenziswa kwezixhobo ezilula kunokucutshungulwa kwiintlobo ezahlukeneyo zeemveliso.Ukwenziwa kweenkuni kudla amandla amancinci kwaye zizinto ezonga amandla.

3, iinkuni aziyi kugqwala, akukho lula ukuba zidliwe.

4. Umthi (umthi owomileyo) une-conductivity ebuthakathaka ekushiseni kunye nombane, impendulo encinci kwiinguqu zeqondo lokushisa, ukutsha okuqinileyo, kwaye akukho nto ibalulekileyo yokwandiswa kwe-thermal kunye nokunciphisa.Ngoko ke, ukhuni lufanelekile ukusetyenziswa ekutshiseni ukushisa kunye neemfuno zokutsha kombane kwiindawo eziphakamileyo.Ifenitshala eyenziwe ngamaplanga inokunika umntu ukufudumala ebusika kwaye ipholile kwinduduzo yasehlotyeni.

I-5, i-overload yomthi ayinayo i-brittle xa iphukile, ukwenzela ukuba ifenitshala yokhuni, yandise ukhuseleko oluthile.

6. Nangona iinkuni ziya kutshisa kwiqondo lokushisa eliphezulu, ukuguqulwa kwesakhiwo somthi esikhulu sincinci kwaye sicotha kunesakhiwo sesinyithi, kwaye sisenako ukugcina amandla athile xa sitshiswa ngokuthe ngcembe okanye i-carbonized, ngelixa isakhiwo sesinyithi siya kukhwela kwaye sidilike. ngokukhawuleza ngenxa yobushushu obuphezulu.

I-7, umbala wokhuni, ipateni enhle, ngexesha elifanayo emva kokugqiba ukunikezelwa kuya kuba mnandi ngakumbi kwiso, ukulungele ukuveliswa kwefenitshala, iibhokisi zezixhobo, ubugcisa kunye nokunye.

Isibini, iziphene ezixhaphakileyo zokhuni

Kukho iingenelo, ngokwemvelo kuya kubakho iintsilelo, nangona iinkuni zineempawu ezininzi ezintle, kodwa ngenxa yezinye iimpawu zabo, kukho iziphene ezixhaphakileyo ezingenako ukuhoywa.Ngezantsi, makhe sithethe ngeentsilelo ezithile.

1, ukhuni luyi-anisotropic ye-heterogeneous material, oko kukuthi, kukho iiyantlukwano ezithile ekusebenzeni kwenxalenye nganye, eboniswa ngokukodwa njengeentlobo zeempawu zomzimba kunye noomatshini bomahluko.Ukwandiswa okungalinganiyo kwandisa ukuguqulwa komthi, kwaye ukuhlukana kwamandla kulula ukukhokelela ekuqhekekeni kweenkuni.

2. Ukhuni luyi-hygroscopic material, oko kukuthi, kulula ukufuma.Ngaloo ndlela phantsi kweemeko zendalo kuya kwenzeka ukunyuka okumanzi, i-shrinkage eyomileyo, ichaphazela ukuzinza kobukhulu bomlinganiswa womthi, oko kulula ukuguqulwa.

3, iinkuni i polima yendalo polymer eziphilayo, nto leyo eyenza ezinye izinambuzane kunye nomngundo (umngundo, iintsholongwane iinkuni ukubola) can parasitic, oko kukuthi, lula ukutsala izinambuzane kunye nomhlwa, ukuze impilo iinkuni, intshabalalo iimveliso zomthi, ebangela umntu omkhulu, izinto eziphathekayo. kunye nelahleko yemali.

4, ukomisa iinkuni kunzima ngakumbi.Iimveliso zokhuni kufuneka zenziwe ngomthi owomileyo.Ukomiswa kweenkuni ukuze kutye amandla amaninzi, kwaye ingqwalasela encinci iya kwenzeka i-warping, i-crack kunye nezinye iziphene, zizisa ilahleko engeyomfuneko.

5. Ukhuni lunokutsha.Apho kusetyenziswe iinkuni ezininzi, kufuneka kuqwalaselwe ukuqinisa amanyathelo okuthintela umlilo.
