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, ugovuze ngokulinganayo futhi uyeke ume imizuzu emi-2, bese ugoqa ngokulinganayo, uthele isixazululo engilazini ehlanzekile eyisicaba, ubeke ingilazi endaweni enomoya futhi enomthunzi, futhi ngokugcwele. omile Okokugcina, hlubula i-coating 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 ukala ngemuva 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.

Indlela yokukhetha 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.
