Eps granular in granular insulation minisiteri nibikoresho byoroheje byimiterere bivanze na anorganic binder, binder organic, afmixture, afmixture kandi yoroheje kandi yoroheje igiteranyo muburyo runaka. Mubushakashatsi buriho no gushyira mubikorwa ePS igenzura ryimikorere, ifu ya landx yinjira igira uruhare runini mumikorere ya minisiteri kandi ifite umubare ugereranije mubiciro, nuko byahoze byibandwaho. Imikorere ihuza ePS ya EPS igenzura ryubushyuhe bwo hanze yuburambe buturuka muri polymer bunder, kandi ibice byayo ahanini ni Vinyl Acetate / Entylene Copolymer. Ubu bwoko bwa polymer burashobora gutera imitsi kugirango ubone ifu ya latex. Bitewe no gutegura neza ifu ya latex mubwubatsi, ubwikorezi bworoshye no kubika byoroshye, ifu yoroshye kuri polymers yahindutse indorerezi yacyo, yo kubika byoroshye no muburyo bworoshye. Imikorere ya EPS insulation ishingiye kuri minisiteri biterwa ahanini nubwoya hamwe na polymer yakoresheje. EVHYNE-vinyl acetate ifu ya latex (eva) hamwe na rowylene ndende kandi hejuru ya tg (ikirahure cyinzibacyuho gito) agaciro gifite imitungo myiza mubijyanye n'ingaruka, imbaraga zubukwe no kurwanya amazi.
Uburyo bwo gukora imikorere yifu ya latex kuri minisiteri biterwa nuko ifu ya polymer ari umuvuduko mwinshi wa molecle hamwe na polar. Iyo RDP ivanze na ePS ibice, igice kitari gisiganwa mumurongo munini wifu ya polymer azagufata kumubiri adsorb hamwe nubuso butarimo pop. Amatsinda ya Polar muri Polymer yerekejwe hanze hejuru ya ePS ibice, bigatuma ibice bya eps bihinduka kuva hydrophodic kuri hydrophilic. Bitewe no guhindura hejuru yibice bya ePS na Polymer Ifu, ikibazo ko ibice bya eP byoroshye guhura namazi byakemuwe. Kureremba, ibibazo byinshi byo gusiga mirtar. Muri iki gihe, mugihe wongeyeho sima no kubyutsa, imitwe ya polar yahishe hejuru ya ePS ibice no guhuza cyane, bitezimbere imikorere ya minisiteri yo kugenzura ePS. Ibi bigaragarira mu kuba eps ibice byoroshye na sima yoroheje, kandi imbaraga zo guhuza byombi ziteye imbere cyane.
Nyuma ya emulsion hamwe nifu ya latex ya latex yashizweho muri firime, irashobora gukora imbaraga zidasanzwe nimbaraga zo guhuza ibikoresho bitandukanye. Zikoreshwa nkuwibunde kabiri muri minisiteri kugirango uhuze na simane idasanzwe binder binder, sima na polymer. Kina imbaraga zijyanye no kunoza imikorere ya minisiteri. Mugukurikirana imiterere yububiko bwa polymer-sima, bifatwa ko kongeramo ifu ya latex ikora igice cyurukuta rwintama, kandi utume umuryango ukora byose binyuze mu mbaraga zimbere za minisiteri. Imbaraga za Polymer, bityo byongera guhangayikishwa na minisiteri no kongera ibibazo bihebuje. Kwiga imikorere ndende yifu yongeye kugaragara muri minisiteri, nyuma yo gusikana microscope ya electrod Gufata ifu ya latex nk'ikintu cy'ubushakashatsi, uburyo bwo gushinga imishinga y'imbaraga za TIF, kandi byagaragaye ko nyuma yuko ubwinshi bw'imiryango yoroha hagati ya minisiteri, bigira ingaruka ku biryo, kandi mu rundi ruhande, inkeri zo mu buryo bworoshye hagati ya minisiteri, ikabasira igorofa ryongeraho ibikubiye muri minisiteri, bigira ingaruka ku mubiri w'imiryango no mu kimenyetso, hanyuma mugihe cyo gushiraho, Polymers nabo bafite ingaruka nziza kubikorwa byo gukumira no kugabanuka kwa sima. Imyanzuro, abafasha bongera imbaraga.
Ongeraho ifu ya latex kuri minisiteri irashobora kunoza imbaraga zibindi bikoresho, kubera ko icyiciro cyamazi cya hydrophilic ifunzwe na capidies ya matrix, mugihe ifu ya laprophilic yinjira muri pore na capillary. Filime y'imbere irashirwaho kandi ihimbajwe cyane ku isi, bityo ibone imbaraga nziza zihuza ibikoresho bya pelile na substrate.
