Kev sib txuas yog dab tsi?
Bonding yog ib txoj hauv kev ruaj khov txuas cov khoom qub lossis cov khoom sib txawv ua ke siv cov nplaum nplaum uas tsim los ntawm cov nplaum nplaum rau ntawm qhov chaw. Bonding yog muab faib ua ob hom:structural bonding thiab non-structural bonding.
Lub luag haujlwm ntawm cov nplaum yog dab tsi?
Cov nplaum nplaum tso siab rau kev sib cuam tshuam ntawm kev sib txuas ntawm kev sib txuas, thiab txuas tshwj xeeb homogeneous lossis heterogeneous thiab complex zoo li cov khoom lossis cov khoom siv los ntawm cov txheej txheem yooj yim, thaum muab qee yam tshwj xeeb, xws li sealing, rwb thaiv tsev, thermal conduction, hluav taws xob conduction, magnetic permeability. , filling, buffering, kev tiv thaiv thiab lwm yam. Ob lub ntsiab ntawm kev sib txuas yog adhesion thiab cohesion. Adhesion yog hais txog kev nyiam ntawm ob qhov chaw sib txawv, thiab cohesion yog hais txog kev nyiam ntawm cov molecules ntawm cov khoom nws tus kheej.
Cov kev sib txuas ua ke yog dab tsi?
1. Butt joint: Qhov kawg ntawm ob lub substrates coated nrog nplaum yog sib txuas ua ke, thiab qhov chaw sib txuas yog me me.
2.Cov pob qij txha thiab T- sib koom ua ke: Nws txuas nrog qhov kawg ntawm ib qho khoom siv hauv paus thiab sab ntawm lwm cov khoom siv hauv paus.
- 3. Lap sib koom tes (pav sib koom ua ke): Nws yog txuas los ntawm ob sab ntawm cov khoom siv hauv paus, thiab qhov chaw sib txuas yog loj dua lub pob tw.
- 4. Lub qhov (socket) sib koom ua ke: ntxig ib qho kawg ntawm kev sib txuas rau hauv qhov sib txawv los yog punched qhov ntawm lwm qhov kawg rau kev sib txuas, lossis siv lub tes tsho los txuas.
Dab tsi yog qhov cuam tshuam rau kev sib raug zoo?
1. Cov khoom yuav tsum tau sib txuas: deg roughness, deg huv si thiab polarity ntawm cov khoom, thiab lwm yam .;
2. Kev sib txuas cov pob qij txha: ntev, nplaum txheej thickness thiab cov ntaub ntawv sib txawv ntawm cov pob qij txha;
3. Ib puag ncig: ib puag ncig (kub / dej / teeb / oxygen, thiab lwm yam), qhov kub thiab txias hloov ntawm qhov chaw gluing;
4. Adhesive: chemical qauv, nkag mus, tsiv teb tsaws, kho txoj kev, siab, thiab lwm yam .;
Dab tsi yog vim li cas rau kev sib txuas tsis ua haujlwm?
Muaj ntau qhov laj thawj rau kev sib koom ua ke tsis ua haujlwm, uas yuav tsum tau txheeb xyuas cov xwm txheej tshwj xeeb. Cov laj thawj feem ntau suav nrog cov hauv qab no:
1. Cov nplaum nplaum thiab cov khoom siv hauv paus tsis sib xws, xws li: tawg tshwm sim ntawm ethanol tshem tawm thiab cov khoom siv hauv PC;
2. Cov kab mob hauv qhov chaw: tso tawm cov neeg ua haujlwm cuam tshuam rau kev sib txuas, flux cuam tshuam rau peb txoj kev tiv thaiv, potting lom, thiab lwm yam;
3. Lub sij hawm luv luv / tsis txaus siab: Tsis txaus siab los yog lub sij hawm tuav lub sij hawm ua rau muaj kev cuam tshuam tsis zoo;
4. Cov nyhuv ntawm qhov kub thiab av noo: cov kuab tshuaj evaporates sai thiab cov txheej txheem nplaum solidifies sai heev;
Nws tuaj yeem pom tias cov kua nplaum tsim nyog yuav tsum tsis yog tsuas yog coj mus rau hauv tus account cov khoom, cov duab, qauv thiab cov txheej txheem gluing ntawm cov khoom sib txuas, tab sis kuj xav txog cov khoom thauj thiab daim ntawv ntawm ntau qhov sib txuas nrog rau ib puag ncig ib puag ncig. Cov yam ntxwv cuam tshuam, thiab lwm yam. Yog tias koj muaj dab tsi koj tsis nkag siab lossis xav tau cov nplaum nplaum, thov hu rauSiway.
