kuqala. Kuqala qonda ukuba yintoniumgubo wepolymer ophinda unyibilike.
Iipowder zepolymer ezisasazekayo ziipolymers ezicoliweyo ezenziwe ngee-emulsions zepolymer ngenkqubo echanekileyo yokomisa ngokutshiza (kunye nokukhethwa kwezongezo ezifanelekileyo). Umgubo wepolymer owomileyo ujika ube yi-emulsion xa udibana namanzi, kwaye unokuphinda unciphe ngexesha lokuxinana kunye nenkqubo yokuqina komota, ukuze amasuntswana epolymer enze isakhiwo somzimba wepolymer kwimota, efana nenkqubo yokusebenza kwe-polymer emulsion, enokuphucula umota wesamente. Isiphumo sesondo. Umota oguqulweyo we-Emulsion dry powder ubizwa ngokuba yi-dry powder mortar (ekwaziwa ngokuba yi-dry mixed mortar, dry mixed mortar). Ekubeni umgubo owomileyo ungadingi ukuqwalasela ukwakheka kwe-emulsion kunye nokuzinza njenge-polymer emulsions, inani elincinci lomxube linokwenza umota ufezekise iipropati ezifunwayo, kwaye uneengenelo zokupakishwa okulula, ukugcinwa, ukuthuthwa kunye nokunikezelwa kune-emulsions, i-antifreeze kunye nokungabikho kokukhula kwesikhunta, Ingxaki yeebhaktheriya eziphilayo, kunye nenzuzo yokuba ungenziwa ube yimveliso yecandelo elinye kunye nokupakisha okuxutyiweyo okulungiselelwe njengesamente kunye nesanti, kwaye ungasetyenziswa emva kokongeza amanzi.
Xa ufaka, xuba kwaye upakishe isanti, isamente, umgubo owomileyo we-emulsion kunye nezinye izongezo ezincedisayo kwangaphambili, kwaye kufuneka wongeze amanzi athile kuphela ngexesha lokwakha kwindawo ukuze wenze udaka lomgubo owomileyo olusebenza ngcono. Eyona nto iphambili ekuvelisweni komgubo we-emulsion owomileyo kukuba amasuntswana e-polymer emva kokusasazwa kwakhona komgubo we-latex abonise ubungakanani besuntswana okanye ukusasazwa kobukhulu besuntswana obufana nobo besuntswana lokuqala lwe-emulsion polymer. Inani elithile le-colloid ekhuselayo efana ne-polyvinyl alcohol kufuneka longezwe kwi-emulsion, ukuze umgubo we-latex uphinde usasazwe kwi-emulsion xa udibana namanzi. Kuphela xa usasazeke kakuhle apho umgubo we-latex unokufumana isiphumo esihle. . Umgubo we-polymer osasazekayo uhlala umgubo omhlophe. Izithako zawo ziquka:
I-resin ye-polymer: Ikwinxalenye ephambili yamasuntswana e-rubber powder, kwaye ikwayeyona nto iphambili kwi-polymer powder ephinda inyibilike.
Isongezelelo (sangaphakathi): kunye ne-resin, idlala indima yokuguqula i-resin. Isongezelelo (sangaphandle): Izinto ezongezelelweyo zongezwa ukwandisa ukusebenza komgubo we-polymer osasazekayo.
I-colloid ekhuselayo: umaleko wezinto ezihlala emanzini ezigqunywe phezu kwamasuntswana e-latex powder aphinda aqhekeke, i-colloid ekhuselayo yomgubo we-latex powder ophinda aqhekeke yi-polyvinyl alcohol.
I-arhente yokulwa nokubopha: isizalisi seminerali esincinci, esisetyenziselwa kakhulu ukuthintela umgubo werabha ekubambeni ngexesha lokugcina nokuthuthwa kunye nokwenza lula ukuhamba komgubo werabha (ophuma kwiingxowa zephepha okanye kwiitanki.)
Ungawubona njani umgangatho we-latex powder ephinda inyibilike?
Indlela 1, indlela yothuthu
Thatha umlinganiselo othile we-latex powder ephinda inyibilike, uyibeke kwisitya sesinyithi emva kokulinganisa, uyifudumeze ukuya kuthi ga kwi-500 degrees, emva kokuyitshisa kubushushu obuphezulu be-500 degrees, uyipholise ifikelele kubushushu begumbi, uze uyilinganise kwakhona. Ubunzima obuphantsi kunye nomgangatho olungileyo.
Indlela yesibini, indlela yokuchithwa
Thabatha umlinganiselo othile we-latex powder ephinda inyibilike uze uyinyibilikise ngamanzi aphindwe kahlanu, uyixube kakuhle uze uyivumele ime imizuzu emi-5 ngaphambi kokuba uyijonge. Ngokomgaqo, xa izinto ezincinci zingena kumaleko osezantsi, kokukhona umgangatho we-polymer powder ephinda inyibilike ungcono. Le ndlela ilula kwaye kulula ukuyenza.
Indlela yesithathu, indlela yokwenza ifilimu
Thatha umgangatho othile we-latex powder ephinda inyibilike, uyinyibilikise emanzini izihlandlo ezi-2, uyixube ngokulinganayo, uyivumele ime imizuzu emi-2, uyixube kwakhona, galela isisombululo kwiglasi ecocekileyo esicaba, kwaye ubeke iglasi kwindawo enomthunzi. Yisuse xa yomile ngokupheleleyo. Jonga ifilimu yepolymer esusiweyo. Icacile kakhulu kwaye isemgangathweni. Emva koko tsala ngokulinganisela, ngokuthamba okuhle kunye nomgangatho omhle. Ifilimu yanqunyulwa yaba yimicu, yantywiliselwa emanzini, yaza yabonwa emva kosuku olu-1, umgangatho wefilimu wawunganyibiliki kangako emanzini. Le ndlela ingenamkhethe ngakumbi
