Ni izihe ngaruka z'ifu ya latex ishobora gukurwamo ku mikorere ya mortilage ya EPS insulation?

EPS granular thermal insulation mortar ni ibikoresho byoroshye byo gukingira ubushyuhe bivanze n'inorganic binder, organic binder, advangement, advangement hamwe n'urumuri rworoheje mu rugero runaka. Mu bushakashatsi buriho ubu n'ikoreshwa rya EPS particle insulation mortar, ifu ya latex ishobora kongera gukoreshwa igira ingaruka zikomeye ku mikorere ya mortar kandi ifite igipimo kinini mu giciro, bityo ikaba ari yo yakunze kwitabwaho. Imikorere yo guhuza ya EPS particle thermal insulation mortar external thermal insulation system ituruka ahanini kuri polymer binder, kandi igice cyayo ahanini ni vinyl acetate/ethylene copolymer. Ubu bwoko bwa polymer emulsion bushobora kumyuka kugira ngo haboneke ifu ya latex ishobora kongera gukoreshwa. Bitewe n'itegurwa neza rya latex ikoreshwa mu bwubatsi, gutwara neza no kubika neza, ifu idafite ishingiro ya polymers yabaye icyerekezo cy'iterambere kubera itegurwa ryayo neza, gutwara neza no kubika neza. Imikorere ya EPS particle insulation mortar iterwa ahanini n'ubwoko n'ingano ya polymer ikoreshwa. Ifu ya ethylene-vinyl acetate latex (EVA) ifite ethylene nyinshi hamwe n'agaciro ka Tg nke (ubushyuhe bw'impinduka mu kirahuri) ifite imiterere myiza mu bijyanye n'imbaraga z'ingaruka, imbaraga z'imibanire n'ubudahangarwa bw'amazi.

Kunoza imikorere y'ifu ya latex ishobora gusubirwamo kuri mortilage biterwa n'uko ifu ya polymer ari polymer ifite molekile nyinshi ifite amatsinda ya polar. Iyo RDP ivanze n'uduce twa EPS, igice kitari polar mu muyoboro mukuru w'ifu ya polymer kizahuzwa n'ubuso butari polar bwa EPS. Amatsinda ya polar muri polymer areba inyuma ku buso bw'uduce twa EPS, bigatuma uduce twa EPS duhinduka kuva ku mazi adafite aho ahuriye n'amazi tujya ku mazi. Bitewe no guhindura ubuso bw'uduce twa EPS n'ifu ya polymer, ikibazo cy'uko uduce twa EPS tworoshye guhura n'amazi kirakemuka. Ibibazo bikomeye byo kureremba, byo gutandukana kwa mortilage. Muri iki gihe, iyo wongeyeho sima no kuvanga, uduce twa polar twinjijwe ku buso bw'uduce twa EPS dukorana n'uduce twa sima kandi tugahuza neza, ibyo bikaba binongera cyane ubushobozi bwo gukora bwa mortilage ya EPS. Ibi bigaragarira mu kuba uduce twa EPS tworoshye gutoswa na sima, kandi imbaraga zo guhuza hagati yabyo zirarushaho kwiyongera cyane.

Nyuma y’uko emulsion n’ifu ya latex ishobora guhindurwamo firime, bishobora gukora imbaraga zo gukomera no gukomera ku bikoresho bitandukanye. Bikoreshwa nk’icyuma cya kabiri gifunga muri mortilage kugira ngo bihuzwe na sima, sima na polimeri. Gukoresha imbaraga zijyanye no kunoza imikorere ya mortilage. Mu kwitegereza imiterere mito y’ibikoresho bya polimeri-simenti, bifatwa ko kongeramo ifu ya latex ishobora guhindurwamo firime bishobora gutuma firime ya polimeri iba igice cy’urukuta rw’umwobo, bigatuma mortilage iba yose binyuze mu mbaraga z’imbere, ibyo bikanoza imbaraga z’imbere za mortilage. Imbaraga za polimeri, bityo byongera imbaraga za mortilage kandi byongera imbaraga za nyuma. Kugira ngo twige imikorere y’igihe kirekire ya latex ishobora guhindurwamo firime muri mortilage, byagaragaye hakoreshejwe microscope ya elegitoroniki, nyuma y’imyaka 10, imiterere mito ya polimeri muri mortilage ntiyahindutse, ikomeza gufatana neza, imbaraga zo guhindagurika no gukomera ndetse n’amazi meza. Hafashwe ifu ya latex ishobora gukurwamo nk'ikintu cy'ubushakashatsi, hakozwe ubushakashatsi ku buryo bwo gushyiraho imbaraga zo gufatanya amatafari, maze byagaragaye ko nyuma yuko polymer yumishijwe ihinduka firime, firime ya polymer yashyizeho isano iri hagati ya sima n'amatafari ku ruhande rumwe, naho ku rundi ruhande, polimeri ziri muri sima zongera umwuka uri muri sima, bigira ingaruka ku buryo ubuso butoshye n'ubushyuhe, kandi nyuma yaho mu gihe cyo gushyiraho, polimeri nazo zigira ingaruka nziza ku buryo sima itoha kandi igacika. Ibikoresho byo gufatanya, ibi byose bifasha kongera imbaraga zo gufatanya.

Kongeramo ifu ya latex ishobora gukurwamo mu gishishwa bishobora kongera imbaraga zo gufatanya n'ibindi bikoresho, kuko igice cy'amazi cy'ifu ya polymer ikunda gushonga n'isima byinjira mu myenge no mu miyoboro y'amaraso ya matrix, mu gihe ifu ya latex yinjira mu myenge no mu miyoboro. Urupapuro rw'imbere rurakorwa kandi rugahambirwa neza ku buso bw'icyuma, bityo bigatuma habaho imbaraga nziza zo gufatanya hagati y'ibikoresho bya gel n'icyuma.
