Chii chinonzi bonding?
Bonding inzira yekubatanidza zvakasimba zvinhu zvakafanana kana zvakasiyana pamwe chete uchishandisa simba rekunamatira rinogadzirwa neadhesive glue panzvimbo yakasimba. Bonding yakakamurwa kuva marudzi maviri:chisungo chekugadzirisa uye chisungo chisingaiti.
Ndeapi mabasa ekunamira?
Iyo yekubatanidza inonamatira inotsamira pakudyidzana kweiyo bonding interface, uye inobatanidza chaiyo homogeneous kana heterogeneous uye yakaoma maumbirwo zvinhu kana zvishandiso kuburikidza nenzira yakapusa maitiro, uku ichipa mamwe mabasa akakosha, sekuisa chisimbiso, insulation, kupisa conduction, magetsi conduction, magineti permeability. , kuzadza, kuvharidzira, kudzivirira nezvimwe zvakadaro. Iwo maviri musimboti wekubatana ndeyekunamatira uye kubatana. Adhesion inoreva kukwezva pakati penzvimbo mbiri dzakasiyana, uye kubatana zvinoreva kukwezva pakati pemamorekuru echinhu chacho.
Ndedzipi nzira dzakajairika dzekubatanidza?
1. Butt joint: Migumo yezvikamu zviviri zvakaputirwa neadhesive zvakabatanidzwa pamwe chete, uye nzvimbo yekubatanidza yekubatanidza idiki.
2.Corner joint uye T- joint: Yakabatanidzwa nekuguma kweimwe base zvinhu uye rutivi rwechimwe chigadziko.
- 3. Lap joint (flat joint): Inobatanidzwa nemativi ehwaro zvinhu, uye nzvimbo yekubatanidza yakakura kudarika butt joint.
- 4. Socket (embedded) joint: isa imwe mugumo wekubatanidza mugomba kana bhomba kune imwe mugumo wekubatanidza, kana kushandisa sleeve kuti ubatanidze.
Ndezvipi zvinhu zvinokanganisa bonding effect?
1. Zvinhu zvinofanira kusungirirwa: hutsinye hwepamusoro, hutsanana hwepamusoro uye polarity yezvinhu, nezvimwewo;
2. Kubatanidza majoini: kureba, adhesive layer thick and different forms of joints;
3. Zvakatipoteredza: zvakatipoteredza (kupisa / mvura / chiedza / oksijeni, nezvimwewo), kutonhora uye kuchinja kwekushisa kwenzvimbo yegluing;
4. Adhesive: chimiro chemakemikari, kupinda, kutama, kurapa nzira, kumanikidza, nezvimwewo;
Ndezvipi zvikonzero zvekukundikana kwekubatana?
Pane zvikonzero zvakawanda zvekutadza kwekubatana, izvo zvinoda kuongororwa kwakadzama kwemamiriro chaiwo. Zvikonzero zvakajairika zvinosanganisira zvinotevera:
1. Kunamatira uye nheyo yezvinhu hazvifananidzi, zvakadai se: kuputika kunoitika pakati pekubvisa ethanol uye PC base material;
2. Kusvibiswa kwepamusoro: Kusunungurwa kwevashandi kunokanganisa kusungirirwa, kuyerera kunobata zvidziviriro zvitatu, potting poisoning, nezvimwewo;
3. Nguva pfupi yekubatana / kusakwana kudzvinyirira: Kusakwana kudzvinyirira kana kudzvinyirira kubata nguva kunokonzera kuipa kwekubatana;
4. Mhedzisiro yekushisa / humidity: solvent inoputika nokukurumidza uye chigadziro chekunamatira chinoomesa nekukurumidza;
Zvinogona kuonekwa kuti yakakodzera yekubatanidza glue solution haifaniri kungofunga nezvezvinhu, chimiro, chimiro uye gluing maitiro ezvikamu zvakasungirirwa, asiwo funga nezvemutoro uye chimiro chezvikamu zvakasiyana-siyana zvakasungwa pamwe chete nenharaunda yakapoteredza. Kufurira zvinhu, nezvimwe. Kana uine chausinganzwisise kana kuti unoda adhesive sealant, ndapota bataSiway.
