Ntugharị na-acha uhie uhie bụ ihe pụrụ iche na polymer pụrụ iche nke polymer na-eme site na ịgba ọkụ na vinyl acetate-ethlene dị ka ihe dị mkpa. Mgbe akụkụ nke mmiri ahụ na-ekupụ, mkpụrụ osisi polymer na-etolite ihe nkiri polymer site na agglomeration, nke na-arụ ọrụ dị ka ihe mkpuchi. Mgbe ejiri na-achagharị anya na-acha uhie uhie na-eji ya na inorganic na-efoning mineral dị ka ciment, ọ nwere ike ịgbanwe ngwa agha. Isi ọrụ nke ntụ ntụ na-acha uhie uhie dị ka ndị a.
(1) Meziwanye ike nkekọ, ike tensile na ike zuru ike.
Mpempe akwụkwọ na-acha odo odo na mbubreyo nwere ike ime ka nkekọ nke ngwa agha mee ka ọ dị mma. Ọnụ ego ahụ buru ibu, ka ukwuu bulie elu. Ike dị elu nwere ike igbochi mkpọtụ ruo ụfọdụ, nrụgide nke nrụrụ ahụ na-adị mfe ịgbasasị ma wepụta ya, yabụ nke njikọ dị ezigbo mkpa maka imeziwanye nguzogide. Nnyocha e mere egosila na ọnya mmetụta nke mkpụrụ osisi celler na polymer ntụ ntụ na-enyere aka ka mma ike nke ngwa agha ciment.
(2) Belata modulu nke ngwa agha nke ngwa agha, nke mere na ihe mgbatị ciment ciment na-emebi emebi nwere ogo mgbanwe.
Adịli modulu nke Redistrible nke Redisperpentible mbubreyo dị ala, 0.001-10GPA; Ọ bụ ezie na motulu ciment dị elu, 10-30gpa, yabụ, ngwa agha nke ciment ga-ebelata na mgbakwunye nke polmer ntụ. Agbanyeghị, ụdị na ego nke polymer ntụ na-enwe mmetụta na modulu nke ike. Na mkpokọta, dị ka oke nke polymer na-abawanye ụba, modulu nke elastic na-ebelata na nrụrụ na-abawanye.
(3) Meziwanye nguzogide mmiri, iguzogide agha alkali, iguzogide na iguzogide nguzogide.
Ihe ngosi nke polymer mechiri oghere na cracks ke composed, ma si otú ahụ na-ebelata ihe mgbochi, na-eme ka ndị na-eguzogide na ntuli mmiri na-eguzogide ndagide ciment. Mmetụta a na-abawanye na ịba ụba nke poment. Mmezi nke iyi na-eguzogide na ụdị polymer ntụ nke polymer ntụ nke polymen ka ciment. Na mkpokọta, yi nguzogide na-eme ka ọ dị ka oke nke polymer na-abawanye.
(4) melite ahihia na ebelata.
(5) melite mbedo nke igwe na-eme ka mmiri belata.
A na-agbasasị polymer emulsion nke polmerble polymerble polymerble polymerble polymerble polymer na-agbasa mmiri na-agbasa mmiri na-agbasasị na ngwa agha, na-aga n'ihu na-aga n'ihu na-aga n'ihu na ngwa agha mgbe ị ga-eme ya. Ihe nkiri ndị a nwere ike igbochi Mbugharị mmiri, si otú a belata ọnwụ mmiri na ngwa agha ahụ ma na-egwu ọrụ na mgbochi mmiri na mmiri.
(6) Belata Prenomenon
Elongation na isi ike nke ngwa agha ciment ciment dị mma karịa ngwa agha ciment nkịtị. Arụmọrụ na-agbanwe agbanwe karịrị ugboro abụọ nke ngwa agha ciment nkịtị; Mmetụta ihe isi ike na-abawanye na mmụba nke polymer ciment. Site na mmụba nke polymer ntụkwụ polymer gbakwunyere, akwara na-agbanwe agbanwe nke polymer nwere ike igbochi mmepe nke cracks, ma n'otu oge ahụ ọ nwere ezigbo nrụgide na-akpata nrụgide.
