Hauv tsab xov xwm dhau los, peb tau kawm txog thawj plaub lub ntsiab lus los txhim kho kev sib raug zoo ntawm kev sib raug zoo

kubyajnplaum.Hnub no Qingdao Sainuo tseem yuav qhia koj txog plaub lub ntsiab lus kawg.

5. Siab

Thaum sib txuas, siv lub siab rau qhov chaw sib txuas kom yooj yim rau cov nplaum los sau cov pits ntawm

nto ntawm adherend, thiab txawm ntws mus rau hauv qhov sib sib zog nqus qhov thiab capillaries kom txo tau kev sib raug zoo ntawm kev sib raug zoo.Rau

adhesives nrog qis viscosity, siab dhau yuav tshwm sim Cov av ntws, ua rau tsis muaj kua nplaum.Yog li ntawd,

lub siab yuav tsum tau siv thaum lub viscosity siab, uas tseem yuav txhawb txoj kev khiav tawm ntawm cov pa ntawm qhov chaw

lub adherend thiab txo cov pores nyob rau hauv lub tsev cog khoom cheeb tsam.

6. Adhesive txheej thickness

Thicker adhesive txheej yog yooj yim los tsim npuas, tsis xws luag thiab tawg thaum ntxov.Yog li ntawd, lub nplaum txheej yuav tsum

yuav ua kom nyias li sai tau kom tau txais kev sib txuas siab dua.Tsis tas li ntawd, thermal expansion ntawm tuab

nplaum txheej tom qab cua sov ua rau cov cua sov nyob rau hauv lub interface cheeb tsam.Qhov kev ntxhov siab kuj muaj ntau dua, uas yuav muaj ntau dua

ua rau kev puas tsuaj.

7. Thauj kev ntxhov siab

Kev ntxhov siab ua rau ntawm qhov sib koom ua ke yog qhov nyuaj, nrog rau kev ntxhov siab shear, tev tawm kev ntxhov siab thiab hloov kev ntxhov siab.

(1) Shear stress: vim yog eccentric nro, kev nyuaj siab concentration tshwm sim ntawm kev sib raug zoo kawg.Ntxiv rau qhov shear

quab yuam, kuj tseem muaj lub zog tensile zoo ib yam nrog cov kev taw qhia interface thiab lub zog tearing perpendicular rau

kev taw qhia interface.Nyob rau lub sij hawm no, nyob rau hauv qhov kev txiav txim ntawm shear kev nyuaj siab, ntau dua lub thickness ntawm adherend, lub

ntau zog ntawm kev sib koom tes.

(2) Sim zam kev siv cov txheej txheem sib koom ua ke uas yuav ua rau muaj kev ntxhov siab thaum lub sij hawm tsim.

(3) Alternating stress: Cov nplaum ntawm qhov sib koom ua ke yog maj mam qaug zog vim qhov kev sib hloov kev ntxhov siab, thiab nws tawg.

nyob rau hauv tej yam kev mob ntau npaum li cas qis dua tus nqi static stress.tawv thiab elastic nplaum (xws li tej yam roj hmab

adhesives) muaj kev qaug zog zoo.

8. Kev ntxhov siab sab hauv

(1) Kev ntxhov siab Shrinkage: Thaum cov nplaum kho tau zoo, lub ntim ntim vim volatilization, txias thiab tshuaj lom neeg.

tshuaj tiv thaiv, ua rau shrinkage kev nyuaj siab.Thaum lub shrinkage quab yuam tshaj lub adhesion quab yuam, qhov pom tseeb daim ntawv cog lus

lub zog yuav txo qis heev.

(2) Thermal stress: Thaum kub kub, thaum lub molten resin txias thiab solidifies, ntim shrinkage yuav tshwm sim,

thiab kev ntxhov siab sab hauv yuav raug tsim tawm ntawm qhov interface vim muaj kev txwv kev sib txuas.Thaum muaj qhov ua tau

slippage ntawm molecular chains, lub internal stress generated disappears.Cov yam tseem ceeb cuam tshuam rau thermal

Kev ntxhov siab yog cov coefficient ntawm thermal expansion, qhov kub thiab txias sib txawv ntawm chav tsev kub thiab Tg, thiab

qhov sib txawv ntawm elasticity.
