Taw qhia rau Interface Agents
Interface agents, raws li cov nplaum, ua lub luag haujlwm tseem ceeb hauv kev kho pob zeb. Txij li cov pob zeb pob zeb feem ntau yog du heev, siv cov neeg ua haujlwm sib txuas tau zoo hloov kho qhov xwm txheej no los ntawm kev ua kom lub substrate nto. Qhov no txhim kho adhesion rau hauv paus txheej, tiv thaiv cov teeb meem xws li hollow me ntsis thiab tev nyob rau hauv plaster txheej. Primers yog dav siv cov neeg ua haujlwm kho mob thoob plaws hauv kev tsim khoom, kev tsim kho, tub rog, thiab lwm yam haujlwm. Lawv txhim kho lossis hloov pauv tag nrho lub cev, cov khoom siv, thiab cov yam ntxwv ntawm cov khoom siv los ntawm kev kho lub cev lossis physicochemical. Cov khoom tsim los hloov kho cov khoom physicochemical ntawm ib qho khoom siv interface kuj tseem hu ua interface modifiers.
Txoj Cai ntawm Kev Ua thiab Kev Ua Haujlwm
Txoj Cai ntawm Kev Ua
Cov primer ua haujlwm los ntawm kev sau cov pores hauv cov phab ntsa substrate, txo nws cov absorbency, thiab yog li muab kev sib raug zoo thiab teeb tsa cov xwm txheej rau cov tshuaj khib nyiab. Tib lub sijhawm, nws ua raws li qhov nruab nrab nplaum nruab nrab ntawm cov phab ntsa thiab cov khoom siv saum npoo av, ua kom tag nrho cov qauv sib txuas rau hauv ib qho kev sib txuas mus tas li.
Cov khoom tseem ceeb
Muaj ob hom kev sib txuas ntawm cov neeg ua haujlwm feem ntau muaj: hmoov qhuav thiab emulsion. Cov hmoov qhuav qhuav cov neeg ua haujlwm feem ntau muaj cov khoom siv tsis zoo xws li cov cement, ua ke nrog cov fillers, polymer hmoov, thiab cov khoom sib xyaw. Lawv muaj kev sib raug zoo siab, dej tsis kam, thiab kev laus ua haujlwm. Thaum siv, lawv yuav tsum tau tov nrog dej raws li cov proportions teev.
