Uruhare rwa redispersible latex ifu ya minisiteri
Kugeza ubu, kubera ko ibicuruzwa bitandukanye byumye byumye byemerwa kandi bigakoreshwa henshi, abantu muruganda bitondera ifu ya redxersible powder nka kimwe mubyongeweho byingenzi byifu ya poro yumye, kuburyo ibintu bitandukanye byagaragaye buhoro buhoro. ifu ya latx, ifu ya polymer nyinshi ya latx, ifu ya resin ya latx, ifu ishingiye kumazi ifu ya latx nibindi.
Imiterere ya microscopique nibikorwa bya macroscopique yaifu ya redxersiblemuri minisiteri ihuriweho, kandi ibisubizo bimwe na bimwe byasesenguwe. Uburyo bwibikorwa bya redispersible latex powder Redispersible latex ifu nugutegura polymer emulion muruvange rushobora gukoreshwa mukumisha spray wongeyeho inyongeramusaruro zitandukanye, hanyuma ukongeramo imiti ikingira hamwe na anti-caking kugirango ukore polymer nyuma yo kumisha spray. Ifu itemba yubusa isubirwamo mumazi. Ifu ya redispersible latex ikwirakwizwa mumashanyarazi yumye. Iyo minisiteri imaze kuvangwa n'amazi, ifu ya polymer isubizwa mumashanyarazi avanze hanyuma ikongera ikarekurwa; kubera hydrata ya sima, guhumeka hejuru hamwe no kwinjiza igipande fatizo, imyenge iri imbere ya minisiteri ni ubuntu. Gukomeza gukoresha amazi hamwe nibidukikije bya alkaline itangwa na sima bituma uduce duto twa latx twuma kugirango habeho firime ikomeza kumazi muri minisiteri. Iyi firime ikomeza ikorwa no guhuza ibice bimwe bitatanye muri emulsiyo mumubiri umwe. Nukubaho kwamafilime ya latex yatanzwe muri polymer yahinduwe ya polymer ituma polimeri yahinduwe ya minisiteri ibona ibimenyetso biranga sima ya sima idashobora gutunga: kubera uburyo bwo kwikuramo bwa firime ya latex, irashobora gushirwa kumutwe cyangwa minisiteri Kuri interineti ya polimeri yahinduwe na base, iyi ngaruka irashobora kunoza imikorere yubusabane bwa minisiteri hamwe nubutaka butandukanye bwa cera. imbaho; Izi ngaruka imbere ya minisiteri irashobora kugumana muri rusange, mu yandi magambo, imbaraga zifatika za minisiteri ziratera imbere, kandi uko ingano y’ifu ya redxersible latx yiyongera, imbaraga z’ubucuti hagati ya minisiteri na base ya beto ziratera imbere ku buryo bugaragara; Hejuru Kuba polimeri ihindagurika kandi yoroheje cyane ya polymer yatezimbere cyane imikorere yo guhuza no guhinduka kwa minisiteri, mugihe moderi ya elastike ya minisiteri ubwayo yagabanutse cyane, byerekana ko ihinduka ryayo ryateye imbere. Filime ya Latex yagaragaye imbere muri minisiteri ya polymer yahinduwe sima kumyaka itandukanye. Filime yakozwe na latex ikwirakwizwa mu myanya itandukanye muri minisiteri, harimo na base-mortar, hagati ya pore, kuzenguruka urukuta rwa pore, hagati y’ibicuruzwa biva mu sima, hafi ya sima, hafi ya agregate, hamwe na interineti-hamwe. Filime zimwe za latex zagabanijwe muri minisiteri yahinduwe nifu ya polymer isubirwamo ituma bishoboka kubona imitungo ya sima ikomeye ya sima idashobora gutunga: firime ya latex irashobora gukuraho ibice byo kugabanuka kumurongo wa base-mortar kandi bigatuma ibice bigabanuka bikira. Kunoza ikidodo cya minisiteri. Gutezimbere imbaraga zifatika za minisiteri: Kuba hariho polymer zihindagurika cyane kandi zoroshye cyane za polymer zitezimbere ubworoherane nubworoherane bwa minisiteri, bitanga ubumwe hamwe nimyitwarire yingirakamaro kuri skeleton ikomeye. Iyo imbaraga zashyizwe mubikorwa, microcrack itinda kugeza igihe impagarara nyinshi zigeze kubera kunoza imiterere no guhinduka. Imiyoboro ya polymer ihuriweho nayo ibuza guhuriza hamwe microcrack mu gucamo ibice. Kubwibyo, redispersible latex ifu yongera kunanirwa kunanirwa no kunanirwa kwibikoresho. Guhindura polymer kuri sima ya sima ituma byombi bibona ingaruka zuzuzanya, kuburyo polymer yahinduwe minisiteri ishobora gukoreshwa mubihe byinshi bidasanzwe. Byongeye kandi, kubera ibyiza bya minisiteri yumye-mugucunga ubuziranenge, ibikorwa byubwubatsi, kubika no kurengera ibidukikije, ifu ya redxersible latex itanga uburyo bwiza bwa tekiniki bwo gukora ibicuruzwa bidasanzwe byumye.
Dushingiye ku buryo bwo gukora ifu ya polymer idasubirwaho muri minisiteri, twakoze ibizamini byo kugereranya kugira ngo tumenye imikorere y’ibindi bikoresho biri ku isoko, bizwi kandi ko ari ifu ya latex, muri minisiteri. 1. Agaciro ka Tg ni -7 ° C, hano bita: redispersible latex powder Fibre fibre: ZZC500 ya sosiyete ya JS Ifu yubucuruzi ya latex ifu yubucuruzi: ifu ya latx iboneka mubucuruzi, yitwa hano ifu ya latx iboneka mubucuruzi ni. Ikibaho cyagutse cya polystirene, ubwinshi ni 18kg / m3, ukata 400 × 400 × 5mm. 2． Ibisubizo by'ibizamini: 2.1 Imbaraga zingana mugihe gitandukanye cyo gukira: Ingero zakozwe ukurikije uburyo bwo gupima imbaraga za minisiteri ya tensile inkomezi muri JG149-2003. Sisitemu yo gukiza hano ni: nyuma yicyitegererezo kimaze gukorwa, irakira umunsi umwe mubihe bisanzwe bya laboratoire, hanyuma igashyirwa mu ziko rya dogere 50. Icyumweru cya mbere cyo kwipimisha ni: shyira mu ziko rya dogere 50 kugeza kumunsi wa gatandatu, kuyikuramo, komeza umutwe wikizamini cyo gukuramo, Ku munsi wa 7, hasuzumwe imbaraga zo gukuramo. Ikizamini mucyumweru cya kabiri ni: shyira mu ziko rya dogere 50 kugeza ku munsi wa 13, ubikuremo, ushyire umutwe wikizamini cyo gukuramo, hanyuma ugerageze imbaraga zo gukuramo kumunsi wa 14. Icyumweru cya gatatu, icyumweru cya kane. . . n'ibindi.
Duhereye kubisubizo, dushobora kubona ko imbaraga zaifu ya redxersiblemuri minisiteri iriyongera kandi ikomeza uko igihe cyubushyuhe bwo hejuru cyiyongera, ibyo bikaba bisa na firime ya latex ifu ya redispersible latex ifumbire muri minisiteri Igitekerezo kirahoraho, igihe kinini cyo kubika, firime ya latx ya poro ya latx izagera ku bucucike runaka, bityo byemeze ko ifatira rya minisiteri hejuru yububiko bwibanze bwa EPS. Ibinyuranye, ifu ya latex yubucuruzi iboneka 97 ifite imbaraga nkeya kuko ibitswe mubushyuhe bwo hejuru mugihe kirekire. Imbaraga zo gusenya ifu ya latx ikwirakwizwa kubuyobozi bwa EPS ikomeza kuba imwe, ariko imbaraga zo gusenya ifu ya latx iboneka mubucuruzi 97 kubuyobozi bwa EPS iragenda iba mibi.
Muri rusange, ubucuruzi bwamavuta ya latx na pisitori ya latx isubirwamo bifite uburyo butandukanye bwibikorwa, kandi ifu ya redispersible latex, ikora firime mubice bitandukanye bya minisiteri, ikora nkibikoresho bya kabiri bya geli kugirango bitezimbere imiterere yumubiri. Uburyo bwibikorwa byimikorere ntibihuye.
