I-polymer powder enokuchithwa kwakhonai-powder e-soluble redispersible powder, eyona nto ixhaphake kakhulu yi-ethylene-vinyl acetate copolymer, kwaye isebenzisa i-polyvinyl alcohol njenge-colloid ekhuselayo.Ke ngoko, umgubo wepolymer odispersible uthandwa kakhulu kwimarike yoshishino lokwakha.Kodwa umphumo wokwakha we-polymer powder owenziwe ngokutsha awunelisekanga ngenxa yokukhetha okungafanelekanga.Ngoko ke kubaluleke kakhulu ukukhetha i-polymer powder echanekileyo, indlela yokuchonga kunye nokukhetha i-polymer powder ephindwe kabini?

Indlela yokuchonga umgubo wepolymer ophinda uhlakazwe

1. Xuba i-polymer powder edispersible kunye namanzi ngomlinganiselo we-1: 5, ugxobhoze ngokulinganayo kwaye uvumele ukuba ume imizuzu emi-5, uze ugcine i-sediment kwinqanaba eliphantsi.Ngokubanzi, okukhona intlenga incinci, kokukhona umgangatho weRDP ungcono.

2. Xubai-polymer powder enokuchithwa kwakhonangamanzi kumlinganiselo we-1: 2, xuba ngokulinganayo, makhe ume imizuzu emi-2, uze udibanise ngokulinganayo, ugalele isisombululo kwiglasi ecocekileyo ecocekileyo, ubeke iglasi emthunzini okhupha umoya, emva kokumisa ngokupheleleyo, hlambulula i-coating. iglasi kwaye ujonge ifilimu yepolymer.Okukhona kubonakala elubala, kokukhona umgangatho womgubo wepolymer odispersible ungcono.Tsala ifilimu ngokuphakathi.Okukhona i-elasticity ingcono, ingcono umgangatho.Sika ifilimu ibe yimichilo.Yayifakwe emanzini, kwaye yabonwa emva kosuku olu-1, ukuchithwa kancinci, kungcono umgangatho.

3. Thatha ubungakanani obufanelekileyo bomgubo wepolymer wokulinganisa, uwubeke kwisikhongozelo sentsimbi emva kokuwulinganisa, ufudumeze ukuya kuthi ga kwi-500℃, uyitshise kubushushu obuphezulu obuyi-500℃, kwaye emva koko ukale emva kokupholisa.Ubunzima obulula, bungcono umgangatho.

4. Uvavanyo lweglue ngebhodi yebhokisi okanye i-veneer.Thatha amaqhekeza amabini amancinci ebhodi yebhokisi okanye ibhodi encinci yesayizi elinganayo, kwaye usebenzise iglue kwi-interface yesampuli.Emva kwemizuzu engama-30 yoxinzelelo kwinto, yikhuphe ukuze ihlolwe.Ukuba inokudityaniswa ngokuqinileyo kwaye i-interface i-100% itshatyalaliswe, ngumgangatho omhle we-RDP.Ukuba i-interface ingatshatyalaliswa ngokuyinxenye kuphela, oko kuthetha ukuba amandla okubambelela e-RDP awalungile kakhulu kwaye umgangatho awufaneleki.Ukuba i-interface icocekile kwaye ayonakaliswanga, ithetha ukuba iphantsi kwaye ingumgunyathi.

Indlela yokukhetha umgubo wepolymer ophinda uhlakazwe

1. Iqondo lobushushu beglasi (TG) lomgubo wepolymer odispersible.Ubushushu beglasi yotshintsho luphawu olubalulekileyo lweempawu ezibonakalayo zeRDP.Kwimveliso ethile, ukhetho olufanelekileyo lobushushu beglasi (TG) ye-RDP inenzuzo yokuphucula ukuguquguquka kwemveliso kunye nokuphepha iingxaki ezifana nokuqhekeka.

2. Ukunyibilika kwakhona.

3. Ubuncinci beqondo lobushushu bokwenza ifilimu (MFFT).Emva kokoi-polymer powder enokuchithwa kwakhonaixutywe namanzi kwaye iphinde i-emulsified, ineempawu ezifanayo kwi-emulsion yasekuqaleni, oko kukuthi, ifilimu iya kwenziwa emva kokuba amanzi aphuke.Ifilimu inokuguquguquka okuphezulu kunye nokunamathela ngokugqwesileyo kwiintlobo ezahlukeneyo ze-substrates.

Oku kungasentla yindlela yokuchonga umgubo wepolymer odispersible kwaye ukhethe umgubo wepolymer odispersible.Abantu abakushishino lokwakha bayayazi iRDP njengokubaluleka kweMichiza yoKwakha.Umgangatho wepolymer powder uhambelana ngokuthe ngqo nomgangatho kunye nenkqubela phambili yokwakha.Kubalulekile ukukhetha i-polymer powder efanelekileyo enokuchithwa kwakhona.
