izinzuzo eziyingqayizivele zokhuni

Okokuqala, izinzuzo eziyingqayizivele zokhuni

I-1, izinkuni ziqinile futhi zihlala isikhathi eside, ikakhulukazi ngenxa yokuthi izinkuni zilula futhi zinamandla aphezulu, isilinganiso samandla nobuningi bokhuni siphezulu kuneso sensimbi evamile.

2, ukusebenza kwezinkuni kuphakeme, ikakhulukazi ngenxa yezinto zokhuni zilula, zithambile, ukusetshenziswa kwamathuluzi alula kungacutshungulwa kube yizinhlobonhlobo zomumo wemikhiqizo.Ukucubungula izinkuni kudla amandla amancane futhi kuyimpahla yokonga amandla.

3, izinkuni ngeke zigqwale, akulula ukugqwala.

4. Izinkuni (izinkuni ezomile) zine-conductivity ebuthakathaka ekushiseni nogesi, ukuphendula okuncane ekushintsheni kwezinga lokushisa, ukuvutha okunamandla, futhi akukho senzakalo esibalulekile sokwanda nokunciphisa okushisayo.Ngakho-ke, izinkuni zifanelekile ukusetshenziswa ekushiseni ukushisa kanye nezidingo zokuvutha kagesi zezindawo eziphakeme.Ifenisha eyenziwe ngokhuni inganikeza umuntu ukushisa ebusika futhi ipholile ehlobo lokunethezeka.

I-5, i-overload yezinkuni ayiyona i-brittle lapho iphukile, ukuze ifenisha yokhuni ikhulise ukuphepha.

6. Nakuba izinkuni zizovutha ekushiseni okuphezulu, ukuguqulwa kwesakhiwo esikhulu sokhuni kuncane futhi kuhamba kancane kunesakhiwo sensimbi, futhi kusengakwazi ukugcina amandla athile lapho kushiswa kancane kancane noma ku-carbonized, kuyilapho isakhiwo sensimbi sizokhasa futhi siwohloke. ngokushesha ngenxa yokushisa okuphezulu.

I-7, umbala wokhuni, iphethini enhle, ngesikhathi esifanayo ngemva kokuqeda ukunikezwa kuyoba okujabulisa kakhulu iso, okufanelekile ukukhiqizwa kwefenisha, amabhokisi wezinsimbi, ubuciko nokunye.

Okwesibili, ukukhubazeka okwandile ngokhuni

Kunezinzuzo, ngokwemvelo kuyoba khona ukushiyeka, nakuba izinkuni zinezimfanelo eziningi ezinhle kakhulu, kodwa ngenxa yezinye izici zabo, kukhona nokukhubazeka okusakazekile okungenakunakwa.Ngezansi, ake sikhulume ngamaphutha athile.

1, ukhuni luyi-anisotropic heterogeneous material, okusho ukuthi, kunomehluko othile ekusebenzeni kwengxenye ngayinye, ikakhulukazi ekhonjiswa njengezinhlobonhlobo zezakhiwo ezingokomzimba nezomshini zomehluko.Ukwandiswa okungalingani kukhulisa ukuguquguquka kokhuni, futhi umehluko wamandla kulula ukuholela ekuqhekekeni kwezinkuni.

2. Ukhuni luyi-hygroscopic material, okusho ukuthi, kulula ukuthola umswakama.Ngakho ngaphansi kwezimo zemvelo kuyokwenzeka ukukhuphuka okumanzi, ukuncipha okomile, kuthinte ukuzinza kobukhulu bohlamvu lwamapulangwe, okulula ukuguqulwa.

I-3, izinkuni ziyi-polymer yemvelo ye-polymer ephilayo, eyenza ezinye izinambuzane kanye nesikhunta (isikhunta, i-wood rot bacteria) ingaba yi-parasitic, okungukuthi, kulula ukuheha izinambuzane nokugqwala, ukuze impilo yezinkuni, ukubhujiswa kwemikhiqizo yezinkuni, okubangela umuntu omkhulu, impahla. kanye nokulahlekelwa ngokwezimali.

4, ukomiswa kwezinkuni kunzima kakhulu.Imikhiqizo yokhuni kufanele yenziwe ngokhuni olomisiwe.Izinkuni omiswe ukuze kudle amandla amaningi, futhi ukunakwa kancane kuzokwenzeka warping, ngokuqhekeka nezinye amaphutha, kuletha ukulahlekelwa okungadingekile.

5. Izinkuni ziyavutha.Lapho kusetshenziswa izinkuni eziningi, kufanele kuqashelwe ukuqinisa izindlela zokuvimbela umlilo.
