I-polymer powder ehlakazeka kabushaiyimpushana ephinde ihlakazeke encibilika emanzini, evame kakhulu i-ethylene-vinyl acetate copolymer, futhi isebenzisa i-polyvinyl alcohol njenge-colloid evikelayo.Ngakho-ke, i-polymer powder ehlakazeka kabusha ithandwa kakhulu emakethe yemboni yezokwakha.Kodwa umphumela wokwakha we-polymer powder owenziwe kabusha awugculisi ngenxa yokukhethwa okungalungile.Ngakho-ke kubaluleke kakhulu ukukhetha impushana ye-polymer ehlakazeka kabusha efanele, indlela yokubona nokukhetha impushana ye-polymer ehlakazeka kabusha?

Indlela yokuhlonza impushana ye-polymer ehlakazeka kabusha

1. Hlanganisa i-polymer powder ephindwe kabusha emanzini ngesilinganiso se-1: 5, gxuma ngokulinganayo futhi uyivumele ime imizuzu engu-5, bese ubheka i-sediment kungqimba olungezansi.Ngokuvamile, uma inzika iyancipha, iba ngcono ikhwalithi ye-RDP.

2. Hlanganisai-polymer powder ehlakazeka kabushangamanzi ngesilinganiso se-1: 2, gubungula ngokulinganayo, ake ume imizuzu emi-2, bese ugoqa ngokulinganayo, uthele isixazululo engilazini ehlanzekile eyisicaba, ubeke ingilazi emthunzini ophefumulayo, emva kokumisa ngokugcwele, hlubula i-coating. ingilazi bese ubuka ifilimu ye-polymer.Uma kuba sobala ngokwengeziwe, iba ngcono ikhwalithi yempushana ye-polymer ehlakazeka kabusha.Donsa ifilimu ngokulingene.I-elasticity engcono, ikhwalithi engcono.Sika ifilimu ibe yimichilo.Yayicwiliswe emanzini, futhi yabonwa ngemva kosuku olu-1, lapho incibilike kancane, ikhwalithi engcono kakhulu.

3. Thatha inani elifanele lempushana ye-polymer ukuze uyikale, uyifake esitsheni sensimbi ngemva kokukala, uyishise ifike cishe ku-500℃, uyishise ekushiseni okuphezulu okungu-500℃, bese uyikala ngemva kokupholisa.Isisindo esilula, ikhwalithi engcono kakhulu.

4. Ukuhlolwa kweglue ngebhodi lebhokisi noma i-veneer.Thatha izingcezu ezimbili ezincane zebhodi lebhokisi noma ibhodi elincanyana elilingana nosayizi, bese usebenzisa i-glue kusixhumi esibonakalayo sesampula.Ngemva kwemizuzu engu-30 yokucindezela entweni, yikhiphe ukuze iyohlolwa.Uma ingaboshelwa ngokuqinile futhi isixhumi esibonakalayo sonakaliswe ngo-100%, iyikhwalithi enhle ye-RDP.Uma isixhumi esibonakalayo singacekelwa phansi kancane, kusho ukuthi amandla okunamathela e-RDP awalungile kakhulu futhi nekhwalithi ayifaneleki.Uma isixhumi esibonakalayo siqinile futhi singonakalisiwe, kusho ukuthi siphansi futhi siwumgunyathi.

Indlela yokukhetha impushana ye-polymer ehlakazeka kabusha

1. Izinga lokushisa lengilazi (TG) lempushana ye-polymer ehlakazeka kabusha.Izinga lokushisa lokushintsha kwengilazi liyinkomba ebalulekile yezakhiwo ezibonakalayo ze-RDP.Ngomkhiqizo othile, ukukhetha okunengqondo kwezinga lokushisa lengilazi (TG) ye-RDP kunenzuzo ukuthuthukisa ukuguquguquka komkhiqizo nokugwema izinkinga ezinjengokuqhekeka.

2. Ukuncibilika kabusha.

3. Izinga lokushisa elincane lokwenza ifilimu (MFFT).Ngemvai-polymer powder ehlakazeka kabushaixubene namanzi futhi i-emulsified kabusha, inezici ezifanayo ne-emulsion yasekuqaleni, okungukuthi, ifilimu izokwakhiwa ngemva kokuba amanzi eqhuma.Ifilimu inokuguquguquka okuphezulu nokunamathela okuhle kakhulu ezinhlobonhlobo zama-substrates.

Okungenhla kuyindlela yokuhlonza impushana ye-polymer ehlakazeka futhi nokukhetha impushana ye-polymer ehlakazeka kabusha.Abantu abasembonini yezokwakha bazi i-RDP njengokubaluleka Kwamakhemikhali Okwakha Ezokwakha.Izinga le-polymer powder lihlobene ngqo nekhwalithi kanye nenqubekelaphambili yokwakhiwa.Kubalulekile ukukhetha impushana ye-polymer ehlakazeka kabusha efanelekile.
