Njengopowder binder, ipolymer powder edispersible isetyenziswa ngokubanzi kushishino lokwakha. Umgangatho wepolymer powder odispersible 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. Ukuqwalasela imbonakalo: sebenzisa intonga yeglasi ukugubungela umlinganiselo omncinci we-latex powder ophindwe kabini kumphezulu weplate yeglasi ecocekileyo ngokucokisekileyo kwaye ngokulinganayo, beka ipleyiti yeglasi kwiphepha elimhlophe, kwaye uhlolisise ngokubonakalayo amasuntswana, izinto zangaphandle kunye ne-coagulation. 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 kwakhona;
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 izixhobo ezingafanelekanga kunye nomxholo ophezulu we-inorganic;
4. Ukuqwalasela indlela yokwenza ifilimu: Ipropati yokwenza ifilimu isisiseko semisebenzi yokuguqulwa kodaka efana nokudibanisa, kunye nepropati yokwenza ifilimu ihlwempuzekileyo, ngokuqhelekileyo ibangelwa ukwanda okugqithisileyo kwezixhobo ze-inorganic okanye i-organic components engafanelekanga. 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 we-latex owenziwe ngokutsha, udibanise namanzi kumlinganiselo we-1: 1 kwaye udibanise ngokulinganayo imizuzu emi-2, uvuselele kwakhona, ugalele isisombululo kwiglasi ecocekileyo ecocekileyo, kwaye ubeke iglasi kwindawo engena umoya kunye ne-shared. Xa yomile ngokupheleleyo, yixobule. Jonga ifilimu yepolymer esusiweyo. Ukucaca 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.
