Amashanyarazi avanze yumye ni ubwoko bwa granule nifu bivangwa kimwe ninyongeramusaruro nka agregate nziza hamwe na binders organique, ibikoresho byo kubika amazi no kubyimba, ibikoresho bigabanya amazi, imiti igabanya ubukana, hamwe nogusebanya muburyo runaka nyuma kumisha no kwerekana.Uruvange rujyanwa ahazubakwa na tanker idasanzwe cyangwa umufuka wimpapuro zidafite amazi, hanyuma ukavangwa namazi.Usibye sima n'umucanga, ikoreshwa rya minisiteri yumye ivanze cyane ni ifu ya polymer.Kubera igiciro cyacyo kinini kandi kigira ingaruka zikomeye kumikorere ya minisiteri, niyo yibandwaho.Uru rupapuro ruvuga ku ngaruka za porojeri ya polymer ikwirakwizwa kumiterere ya minisiteri.
Uburyo bwo kugerageza
Kugirango hamenyekane ingaruka ziterwa nifu ya polymer itandukanijwe kumiterere ya polymer mortar, amatsinda menshi ya formula yateguwe nuburyo bwo gupima orthogonal kandi yapimwe hakurikijwe uburyo bwa "Ubugenzuzi Bwiza Bwiza bwa Polymer Mortar kububiko bw’ubushyuhe bwo hanze" DBJOI- 63-2002.Byakoreshejwe kugirango hamenyekane ingaruka za polymer mortar ku mbaraga zingana zingana, imbaraga zo guhuza inkweto zifatika zifatika zifatika hamwe nimbaraga zo guhonyora, imbaraga zihindagurika hamwe no kwikuramo inshuro ebyiri za polymer mortar ubwayo.
Ibikoresho nyamukuru ni P-04 2.5 sima isanzwe ya silika;RE5044 na R1551Z ifu ya latx isubirwamo kandi idasubirwaho;70-140 mesh quartz umucanga;ibindi byongeweho.
2 Ingaruka yifu ya polymer itatanye kumiterere ya polymer mortar
2.1 Guhuza ibintu hamwe no kwikuramo ibyuma byo guhuza ibintu
Hamwe n'ubwiyongere bw'ifu ya polymer itatanye, imbaraga zingirakamaro zingirakamaro hamwe nimbaraga zo gukomeretsa inkweto za polymer mortar na sima na sima nazo zariyongereye, kandi imirongo itanu yazamutse ibangikanye no kwiyongera kwa sima.Impuzandengo iremereye ya buri ngingo ifatika irashobora gusesengura ingano yingaruka ziterwa nibiri mu ifu ya polymer idasubirwaho ku mikorere ya sima.Imbaraga zo kwikuramo imbaraga zerekana umurongo wo gukura.Muri rusange icyerekezo ni uko imbaraga zingana zingana ziyongera kuri 0.2 MPa naho imbaraga zo gukata zogosha ziyongera kuri 0.45 MPa kuri buri kwiyongera kwa 1% kumashanyarazi ya polymer.
2.2 Kwiyunvisha / kugwiza ibintu bya minisiteri ubwayo
Hamwe n'ubwiyongere bw'ifu ya polymer isubirwamo, imbaraga zo gukomeretsa n'imbaraga zo guhuza imbaraga za polymer ubwayo byagabanutse, byerekana ko polymer igira ingaruka zibangamira amazi ya sima.Ingaruka ziterwa nifu ya polymer itandukanijwe kumubare wikigereranyo cya polymer mortar ubwayo irerekanwa mumashusho ya 4., hamwe no kwiyongera kwifu ya pisitori ya latxersible, igipimo cyo guhunika cya polymer mortar ubwacyo kiragabanuka, byerekana ko polymer itezimbere ubukana bwa minisiteri.Impuzandengo iremereye ya buri ngingo ijyanye irashobora gusesengura mu buryo bugereranije urugero rwingaruka ziterwa nifu ya polymer yisubiramo kumikorere ya polymer ubwayo.Hamwe no kwiyongera kwimyunyu ngugu ya polymer isubirwamo, imbaraga zo guhonyora, imbaraga za flexural hamwe na Indentation igipimo cyerekana umurongo ugabanuka.Kuri buri 1% kwiyongera kwifu ya polymer itatanye, imbaraga zo kwikuramo zigabanuka kuri 1.21 MPa, imbaraga za flexural zigabanuka 0.14 MPa, naho igipimo cyo kwikuramo-kugabanuka kigabanuka 0.18.Birashobora kandi kugaragara ko ubworoherane bwa minisiteri butezimbere bitewe no kwiyongera kwinshi kwifu ya polymer.
2.3 Isesengura ryinshi ryingaruka zingero zumucanga kumiterere ya polymer mortar
Muri polymer mortar, imikoranire iri hagati yikigereranyo cyumucanga numusemburo wa polymer isubirwamo bigira ingaruka kumikorere ya minisiteri, bityo rero birakenewe ko tuganira ku ngaruka ziterwa na lime-sand ukwe.Ukurikije uburyo bwo gupima amakuru ya orthogonal, ibipimo bitandukanye bya lime-umucanga bikoreshwa nkibintu bihinduka, kandi ibirimo bifitanye isano na redispersible polymer ifu ikoreshwa nkikintu gihoraho cyo gushushanya igishushanyo mbonera cyerekana ingaruka ziterwa numubare wumucanga kuri minisiteri.Birashobora kugaragara ko, Hamwe niyongerekana ryikigereranyo cyumusenyi, imikorere ya polymer mortar na sima ya minisiteri hamwe nimikorere ya polymer mortar ubwayo yerekana umurongo ugabanuka.Imbaraga zubusabane zagabanutseho 0.12MPa, imbaraga zo gukata inkweto zo kugabanuka zigabanukaho 0.37MPa, imbaraga zo kwikuramo polymer mortar ubwazo zigabanukaho 4.14MPa, imbaraga za flexural zigabanuka 0,72MPa, hamwe no kwikuramo inshuro igipimo cyagabanutseho 0.270
3 Ingaruka yifu ya redxersible latex irimo f ku guhuza kwinshi kwa polymer mortar hamwe na EPS ifuro ifuro rya polystirene Guhuza polymer mortar na sima ya minisiteri no guhuza ubuyobozi bwa EPS byasabwe na DB JOI-63-2002 biravuguruzanya.
Iyambere isaba gukomera cyane kwa polymer mortar, mugihe iyanyuma isaba guhinduka cyane, ariko urebye ko umushinga wo gukwirakwiza amashyuza yo hanze ugomba gukomera kumpome zombi zikomeye ndetse no ku mbaho za EPS zoroshye, icyarimwe, birakenewe ko igiciro ari ntabwo ari hejuru cyane.Kubwibyo, umwanditsi yanditse urutonde rwingaruka ziterwa nifu ya polymer kubintu byoroshye guhuza imiterere ya polymer minar ukwayo kugirango ashimangire akamaro kayo.
3.1 Ingaruka zubwoko bwifu ya polymer itatanye kumubano wububiko bwa EPS
Ifu ya redispersible latex yatoranijwe mumahanga R5, C1, P23;Abanya Tayiwani D2, D4 2;murugo S1, S2 2, yose hamwe 7;ikibaho cya polystirene cyatoranijwe Beijing 18kg / EPS.Ukurikije DBJ01-63-2002, ikibaho cya EPS kirashobora kuramburwa no guhuzwa.Ifu ya redispersible latex irashobora kuba yujuje ibyangombwa bisabwa kandi byoroshye guhuza imiterere ya polymer mortar icyarimwe.
