Uruhare rwa redispersible latex ifu ya minisiteri

1. Uburyo bwibikorwa byifu ya latx ikwirakwizwa muri minisiteri

Ingano ya emulion polymer ishobora gukorwa mugushonga ifu ya latx yatatanye mumazi ihindura imiterere ya pine ya minisiteri, kandi ingaruka zayo zo guhumeka ikirere zigabanya ubucucike bwa minisiteri, iherekejwe no kugabanya imyenge ikomeye no gukwirakwiza kimwe muri rusange. . Polimeri itangiza umubare munini wimyuka ntoya ifunze ikirere cyinshi muri sima ya sima, itezimbere cyane imikorere ya minisiteri ivanze. Muri icyo gihe, ibyo byuka byo mu kirere birashobora guhagarika capillary imbere ya minisiteri ikomye, kandi hydrophobique igaragara hejuru ya capillary ifunze. Ingirabuzimafatizo; icy'ingenzi cyane, iyo sima iyobowe, polymer nayo ikora firime kandi ikomeka kuri hydrata ya sima kugirango ibe imiterere imwe y'urusobe, kandi polymer na hydrate byinjirana kugirango bikore icyiciro gikomeza. Iyi miterere igizwe na polymer-yahinduwe na sima ya sima, kandi igiteranyo nacyo gihujwe na minisiteri ikomye hamwe nibikoresho. Bitewe na modulus nkeya ya polymer, imiterere yimbere yimbere ya sima ya sima iratera imbere, ishobora kwihanganira guhindagurika no kugabanya imihangayiko, kandi amahirwe yo gucika mikoro nayo ni mato; byongeye, fibre fibre yambukiranya micro-crack kandi ikora nkikiraro no kuzuza Ingaruka igabanya ikwirakwizwa ryimyanda kandi bigatuma uduce duto duto tubura ahantu hari polymers nyinshi. Kugabanuka kwa micro-frake imbere muri slurry bigabanya ubushobozi bwo kwinjiza amazi ya capillary imbere ya minisiteri, kandi ubushobozi bwo kwinjiza amazi ya minisiteri buratera imbere icyarimwe.

2. Kurwanya ubukonje

Igipimo cya freze-thaw igihombo cya sima ya minima yipimishije hamwe nifu ya latex iri hasi cyane ugereranije nicyitegererezo utongeyeho ifu ya latex, kandi hamwe no kwiyongera kwifu ya latex, uko igipimo cyigihombo kinini ari gito, niko gukonjesha ari byiza. -kurwanya kurwanya ikizamini ni. , iyo ibirimo ifu ya latex irenze 1.5%, igipimo cyigihombo kinini cya freeze-thaw gihinduka gake.

3. Ingaruka yifu ya latex kumikorere ya minisiteri

Imbaraga zo guhonyora za minisiteri zigabanuka hamwe no kwiyongera kwifu ya latex, kandi iyo ivanze na selile ya ether, imbaraga zo kwikuramo zirashobora kugabanuka neza; imbaraga za flexural nimbaraga ziyongera hamwe no kwiyongera kwifu ya latex; Iyo ingano yifu ya latex iri munsi ya 2%, imbaraga zububiko bwa minisiteri ziyongera cyane, hanyuma kwiyongera bikadindira; ifu ya latex irashobora kunoza cyane imikorere yuzuye ya minisiteri, kandi umubare ukwiye ni 2% -3% byibikoresho bya sima.

4. Agaciro k'isoko hamwe nicyizere cya powderx yahinduwe minisiteri yubucuruzi

Gukoresha ifu ya latex kugirango uhindure isima ya sima irashobora kubyara ifu yumye yumurimo hamwe nibikorwa bitandukanye, itanga isoko ryagutse ryubucuruzi bwa minisiteri. Kimwe na beto yubucuruzi, minisiteri yubucuruzi ifite ibiranga umusaruro uhuriweho hamwe nogutanga hamwe, bishobora gutanga uburyo bwiza bwo gukoresha ikoranabuhanga nibikoresho bishya, gushyira mubikorwa igenzura ryiza, kunoza uburyo bwubwubatsi, no kwemeza ubwiza bwumushinga. Ubusumbane bwa minisiteri yubucuruzi mubijyanye nubwiza, imikorere, ubukungu no kurengera ibidukikije byagaragaye cyane hamwe nubushakashatsi niterambere, kumenyekanisha no kubishyira mu bikorwa, kandi bigenda byamenyekana buhoro buhoro. Irashobora gukusanyirizwa mumagambo umunani: imwe irarenze, ibiri irihuta, itatu ni nziza, nintara enye (imwe ni myinshi, hariho ubwoko bwinshi; kuzigama umurimo, kuzigama ibikoresho, kuzigama amafaranga, nta mpungenge) . Byongeye kandi, ikoreshwa rya minisiteri yubucuruzi irashobora kugera ku myubakire y’umuco, kugabanya ibibanza byegeranye, no kwirinda ivumbi, bityo kugabanya ibidukikije no kurinda isura y’umujyi.
