Njengopowder binder, i-polymer powder edispersible isetyenziswa ngokubanzi kushishino lokwakha.Umgangatho womgubo wepolymer owenziwe ngokutsha uhambelana ngokuthe ngqo nomgangatho kunye nenkqubela phambili yokwakha.Ngophuhliso olukhawulezayo, kukho ukwanda kwe-R&D kunye namashishini emveliso angena kwiimveliso zomgubo wepolymer ezihlakazekayo, kwaye abasebenzisi banokhetho oluninzi nangakumbi, kodwa kwangaxeshanye, umgangatho womgubo wepolymer odispersible ubuye ungalingani kwaye uxubene.Ukuze kuncitshiswe iindleko, abanye abavelisi bayayigatya imigangatho yomgangatho, i-shoddy, kwaye abanye bade bayithengise ngamaxabiso aphantsi phantsi kwe-redispersible polymer powder kunye ne-resin ye-rubber powder ngokubanzi, engaphazamisi imarike kuphela kodwa iyabakhohlisa.umthengi.
Indlela yokwahlula umgangatho wepolymer powder ephinda ihlakazeka?Nazi ezinye iindlela zokuqala zokuchonga umgangatho womgubo welatex ophinda uhlakazwe:
1. Ukujonga imbonakalo: sebenzisa intonga yeglasi ukugquma umgubo omncinci welatex odispersible kumphezulu wepleyiti yeglasi ecocekileyo kancinci kwaye ngokulinganayo, beka ipleyiti yeglasi kwiphepha elimhlophe, kwaye ujonge ngokubonakalayo amasuntswana, izinto zangaphandle kunye nokuqina. .Umphandle.Ukubonakala kwe-latex powder ehlaziywayo kufuneka ibe ngumgubo omhlophe okhululekileyo okhululekileyo ngaphandle kokuvumba okucaphukisayo.Iingxaki zomgangatho: umbala ongaqhelekanga we powder latex;ukungcola;amasuntswana arhabaxa;ivumba elibi;
2. Isigwebo ngendlela yokutshatyalaliswa: thatha umlinganiselo othile we-latex powder odibeneyo kwaye unyibilike ngamaxesha angama-5 ubukhulu bamanzi, ugxobhoze kakuhle kwaye uvumele ukuba ume imizuzu emi-5 ngaphambi kokujonga.Ngokomgaqo, ukunyamezelwa okuncinci okuhlala kumaleko asezantsi, ngcono umgangatho womgubo wepolymer owenziwe ngokutsha;
3. Ukuqwalasela umxholo womlotha: thatha umlinganiselo othile we-latex powder, uyibeke kwisitya sentsimbi emva kokulinganisa, ushushu ukuya kuma-800 ℃, emva kokutshisa kwe-30min, uyipholise kwiqondo lokushisa, kwaye uphinde ulinganise.Ubunzima obulula busemgangathweni olungileyo.Ubunzima bokukhanya kunye nomgangatho omhle.Uhlalutyo lwezizathu zesiqulatho sothuthu oluphezulu, kubandakanywa izinto ezingafanelekanga kunye nomxholo ophezulu we-inorganic;
4. Ukuqwalasela indlela yokwenza ifilimu: Ipropati yokwenza ifilimu isiseko semisebenzi yokuguqulwa kodaka efana nokudibanisa, kunye nepropathi yokwenza ifilimu ihlwempuzekileyo, edla ngokubangelwa ukwanda okugqithisileyo kwezixhobo ze-inorganic okanye izinto ezingafanelekanga. .I-latex powder ehlaziywayo yomgangatho omhle ineempawu ezintle zokwenza ifilimu kwiqondo lokushisa lokushisa, kodwa iipropati zokwenza ifilimu kwiqondo lokushisa lokushisa azilungile, kwaye ininzi yazo ineengxaki zomgangatho ngokubhekiselele kwi-polymer okanye umxholo womlotha.
Indlela yokuvavanya: Thatha umgangatho othile womgubo welatex ophinda uhlakazwe, uxube namanzi kumlinganiselo we-1: 1 kwaye uvuthulule ngokulinganayo imizuzu emi-2, uvuselele kwakhona, ugalele isisombululo kwiglasi ecocekileyo, kwaye ubeke iglasi kwindawo. indawo enomoya kunye nenomthunzi.Xa yomile ngokupheleleyo, yixobule.Jonga ifilimu yepolymer esusiweyo.Ukungafihli okuphezulu kunye nomgangatho olungileyo.Emva koko tsala ngokuphakathi, kunye ne-elasticity elungileyo kunye nomgangatho olungileyo.Emva koko ifilimu yanqunyulwa ibe yimichilo, ifakwe emanzini, kwaye yabonwa emva komhla we-1, umgangatho wefilimu wawuncitshiswe ngaphantsi kwamanzi.
Oku ngasentla kuyindlela nje elula, engenakuchongwa ngokupheleleyo njengelungileyo okanye embi, kodwa ukuchongwa kwangaphambili kunokwenziwa.Yongeza umgubo werabha kumdaka ngokwemiyalelo yokusetyenziswa, kwaye uvavanye udaka ngokwemigangatho yodaka ehambelanayo.Le ndlela inenjongo ngakumbi.
