Ungayibona kanjani futhi ukhethe impushana ye-latex ehlakazeka kabusha?

Redispersible latex powder iyimpushana encibilika kabusha encibilika emanzini, eyi-copolymer ye-ethylene ne-vinyl acetate, ene-polyvinyl alcohol njenge-colloid evikelayo. Ngakho-ke, i-latex powder e-redispersible ithandwa kakhulu emakethe yemboni yezokwakha, futhi umphumela wokwakha awulungile ngenxa yokukhethwa okungalungile kwe-latex powder. Kubalulekile ukukhetha impushana ye-latex ehlakazeka kabusha efanelekile, ngakho-ke ungayibona kanjani futhi ukhethe impushana ye-latex ehlakazeka kabusha?

Indlela yokuhlonza impushana ye-latex ehlakazeka kabusha

Hlanganisa i-latex powder namanzi e-redispersible kanye namanzi ngesilinganiso se-1: 5, gxuma ngokulinganayo futhi uyivumele ime imizuzu engu-5, bese ubheka i-sediment ngezansi. Ngokuvamile, ukuncipha kwenhlabathi, kuba ngcono ikhwalithi yempushana ye-latex ehlakazeka kabusha.

Xuba impushana ye-latex ehlakazeka kabusha namanzi ngesilinganiso se-1: 2, gudluza ngokulinganayo bese uvumela ukuthi ime imizuzu engu-2, bese ugoqa ngokulinganayo, uthele isisombululo engilazini ehlanzekile eyisicaba, ubeke ingilazi endaweni enomoya futhi enomthunzi, futhi ngokugcwele. yomile Ekugcineni, cwecwa ukugqoka engilazini bese ubuka ifilimu ye-polymer. Uma kubonakala obala, ikhwalithi ye-latex powder iba ngcono. Bese udonsa ifilimu ngokulingene. I-elasticity engcono, ikhwalithi engcono. Sika ifilimu ibe yimichilo Gcoba emanzini, bheka emva kosuku olu-1, izinga lokuncibilika kancane lingcono.

Thatha inani elifanele lempushana ye-latex futhi uyikale. Ngemva kokulinganisa, yibeke esitsheni sensimbi, sishise kuze kufike kuma-degree angama-500, sishise ekushiseni okuphezulu kwama-degrees angu-500, bese silinganisa ngemva kokupholisa. Isisindo esilula, ikhwalithi engcono kakhulu.

Hlola ngeglue ebhodini lebhokisi noma i-veneer. Thatha amabhodi amabhokisi amabili amancane noma amabhodi okhuni amancane anosayizi olinganayo, bese usebenzisa i-glue esibonakalayo sesampula. Ngemva kwemizuzu engu-30 yokucindezela entweni, yikhiphe ukuze iyohlolwa. Uma ingahlanganiswa ngokuqinile futhi i-100% ye-interface ibhujiswa, iwumkhiqizo omuhle wekhwalithi ye-latex powder. Uma isikhombimsebenzisi singabhujiswa kancane kuphela, kusho ukuthi amandla okubopha we-latex powder awalungile kakhulu futhi ikhwalithi ayifaneleki. Uma isixhumi esibonakalayo siqinile futhi singonakalisiwe, kusho ukuthi sisezingeni eliphansi futhi siwumgunyathi.

Ungakhetha kanjani i-latex powder ehlakazekayo

Izinga lokushisa lokushintsha kwengilazi lempushana ye-latex ehlakazeka kabusha. Izinga lokushisa lokushintsha kwengilazi liyinkomba ebalulekile yezakhiwo ezibonakalayo ze-latex powder ehlakazeka kabusha. Ngomkhiqizo othize, ukukhethwa okunengqondo kwezinga lokushisa lokushintsha kwengilazi yempushana ye-latex edispersible kulungele ukuthuthukisa ukuguquguquka komkhiqizo nokugwema izinkinga ezifana nokuqhekeka.

Ukuxazululeka.

Izinga lokushisa eliphansi lokwenza ifilimu. Ngemuva kokuthi i-latex powder ehlakazeka kabusha ihlanganiswe namanzi futhi iphinde ifakwe emulsified, inezici ezifanayo ne-emulsion yasekuqaleni, okungukuthi, ifilimu izokwakhiwa ngemva kokuba amanzi eqhuma. Ifilimu inokuguquguquka okuphezulu nokunamathela okuhle kuma-substrates ahlukahlukene.

Okungenhla kuyindlela yokuhlonza impushana ye-latex ehlakazeka kabusha nokukhetha impushana ye-latex ehlakazekayo ukuze uthole inkomba yakho. Noma ubani obambe iqhaza embonini yezokwakha uyazi ukubaluleka kwayo. Izinga le-latex powder lihlobene ngokuqondile nekhwalithi kanye nenqubekelaphambili yokwakhiwa. Kubalulekile ukukhetha impushana ye-latex ehlakazeka kabusha efanele.
