Adhesion - Iyini?

Kunezindlela eziningi ezahlukene budlelwane emkhatsini wetincenye nemizimba yenyama. Omunye walena uwukuba ebusweni adhesion. Ake sibheke ukuthi lesi simo futhi lokho izakhiwo.

Kuyini adhesion

Inchazelo kuyacaca okwengeziwe uma sifuna ukuthola ukuthi kwamiswa leli gama. Nge adhaesio Latin elihunyushwe ngokuthi "ukuthatheka, adhesion, adhesion". Ngakho, adhesion - akuyona nje uxhumano zemizimba heterogeneous olujiyile okwenzeka contact abo. Lapho edlubhe ebusweni contact, kukhona icala okhethekile ukuxhumana. Wabiza autohesion. Kuzo zombili lezi zimo kungenzeka ukudweba ecacile isigaba umngcele emkhatsini wetintfo idatha. Ngokuphambene, secrete nokubumbana, lapho amangqamuzana adhesion ngaphakathi impahla ngokwayo. Ukuze wenze kube sobala, cabangela isibonelo nokuphila. Thatha PVA glue namanzi abavamile. Khona-ke uzisebenzise ezingxenyeni ezihlukahlukene okufanayo ingilazi ebusweni. Kulesi sibonelo, amanzi kuyinto into okuyinto abazalwa nawo adhesion abampofu. Kulula ukuhlola ngokuvula ingilazi esiphendula esibhekisa phansi. Ukubumbana futhi ephawula amandla ejenti. Uma lezo izingcezu ezimbili ingilazi nge ingcina, ukuxhumana kuyoba okunokwethenjelwa ngokwanele, kodwa uma uhlanganisa nabo plasticine, ukudabuka zokugcina phakathi. Kusukela lokho singaphetha ngokuthi nokubumbana yayo ngoba obuqinile ngeke kwanele. Singasho ukuthi zombili lezi amabutho umphelelisi nomunye.

Izinhlobo adhesion futhi izici ezithinta amandla ayo

Kuye ngalokho umzimba basabela nomunye, avele izici ezithile okunamathiselwe. Inani eliphakeme limelela adhesion okwenzeka ukuxhumana eqinile. Le mpahla inenzuzo yangempela enkulu ekwakhekeni anamathelayo ahlukahlukene. Ngaphezu kwalokho, namanje secrete adhesion ukudla okuqinile futhi uketshezi. Kunezici eziningana ezingase ukhiye bungabonakala ukuthi ngokuqondile kunqunywa amandla ngawo babonakalise adhesion. Le ndawo yokuxhumana, ubunjalo emizimbeni ixhumana kanye izakhiwo ezishelelayo yabo. Ngaphezu kwalokho, uma okungenani eyodwa pair of izinto uzalela icala kagesi okuzovela nokuxhumana isibopho donor-acceptor, okuzokwenza ngcono traction. A indima ebalulekile udlalwa ngu ukufingqa capillary ye umhwamuko phezu. Ngenxa lokhu mkhuba phakathi substrate kanye ingcina singenzeka ukusabela ikhemikhali kwandisa amandla okuxhumana. Uma umzimba okuqinile ukushonisa ku ketshezi, singabona yalokho ukuthi abangela adhesion - is ogelezayo nokumanzisa. Lesi simo esiyingqayizivele sibangelwa livame ukusetshenziswa for Umdwebo, gluing, nokunamathisela ngomthofu, Lubrication, amatshe nokunonophala, njll Ukuqeda adhesion igrisi isetshenziswa, okuyinto kuvimbela ukuxhumana ngqo ye evele, futhi ukuze luqine, Ngakolunye uhlangothi, ukukhiqiza ukusebenza ebusweni by ukwelashwa mechanical imisebe noma amakhemikhali, ukuchayeka emisebeni kagesi noma ukwengeza ukungcola ahlukahlukene sokusebenza. Quantitatively, degree of ukuxhumana okunjalo kunqunywa amandla okufanele zisetshenziswe ukuze zehlukanise phakathi kwemini evele Ixhumana ne. Ukuze ukukala amandla adhesion, idivayisi elikhethekile okuthiwa i adgeziometrami. Isethi kakhulu efanayo izindlela zokunquma kulokhu salo adgeziometrii aziwayo.
