Umxholo womlotha ovela kwisiqheloi-polymer powder enokuchithwa kwakhonaumzi-mveliso uqhele ukuba yi-10±2
Umgangatho womxholo womlotha ungaphakathi kwe-12%, kwaye umgangatho kunye nexabiso zithelekiseka
Olunye umgubo welatex wasekhaya ungaphezulu kwe-30%, kwaye eminye irabha yomgubo inothuthu ukuya kuma-50%.
Ngoku umgangatho kunye nexabiso lepolymer echithwayo kwimarike ayilingani, zama ukukhetha
Umxholo ophantsi wothuthu, ukusebenza kweendleko eziphezulu kunye nomgangatho ozinzile wokubonelela.
Unokukhetha njani umgubo welatex ophinda uhlawulwe, ngokuqhelekileyo akunakwenzeka ukuba uqalise xa usenza ifomula,
Ayikho enye indlela esebenzayo ngaphandle kokuyibeka kwimveliso yovavanyo.
Ukukhethwa kwepolymer powder efanelekileyo enokuchithwa kufuneka kuthathelwe ingqalelo kule miba ilandelayo:
1. Ubushushu beglasi benguqu yomgubo wepolymer ehlakazekayo.
Ubushushu beglasi yokutshintsha yipolymer ebonisa ukuqina;ngaphantsi kobu bushushu, ipholima ibonisa ukuqaqadeka.
Ngokubanzi, iqondo lobushushu beglasi yomgubo welatex yi -15±5℃.
Ngokusisiseko akukho ngxaki.
Ubushushu beglasi yotshintsho luphawu oluphambili lweempawu ezibonakalayo zepolymer powders, kunye neemveliso ezithile,
Ukhetho olufanelekileyo lobushushu beglasi yokutshintsha kwepolymer ephinda iphinde iphinde iphinde iphinde ibe ngumgubo inceda ekwandiseni ukuguquguquka kwemveliso kunye nokuphepha.
ukuqhekeka, njl.
2. Ubuncinane befilimu yokwenza iqondo lokushisa
Emva kokuba i-polymer ehlaziywayo kunye ne-dispersible powder powder ixutywe namanzi kwaye i-emulsified, ineempawu ezifanayo kwi-emulsion yokuqala.
Okokuthi, emva kokuba amanzi aphuke, ifilimu iya kwenziwa, enokuguquguquka okuphezulu kunye nokubambelela kakuhle kwii-substrates ezahlukeneyo.
Ubuncinci befilimu yokwenza ifilimu ye-latex powder eveliswe ngabavelisi abahlukeneyo iya kuba yinto eyahlukileyo.
Isalathiso sabanye abavelisi yi-5 ℃, okoko nje i-latex powder enomgangatho olungileyo inobushushu bokwenza ifilim phakathi kwe-0 kunye ne-5 ℃.
3. Iipropati eziphinda zinyibilike.
Iipolymer powders ezinokuthi zihlakazeke ngokuyinxenye okanye zinqabile ukuba zinyibilike kumanzi abandayo okanye kumanzi anealkaline.
4. Ixabiso.
Umxholo oqinileyo we-emulsion umalunga ne-53%, oku kuthetha ukuba malunga neetoni ze-1.9 ze-emulsion ziqina kwitoni enye ye-rubber powder.
Ukuba ubala i-2% yamanzi, yi-1.7 yeetoni ze-emulsion ukwenza itoni enye yomgubo werabha, kunye ne-10% yothuthu,
Kuthatha malunga neetoni ezi-1.5 ze-emulsion ukuvelisa itoni enye yomgubo werabha.5. Isisombululo samanzi se-latex powder
Ukuze uvavanye i-viscosity ye-latex powder, abanye abathengi bavele banyibilikise i-latex powder
Emva kokuyixuba emanzini, ndayivavanya ngesandla, ndafumanisa ukuba ayincangathi, ngoko ndacinga ukuba yayingengomgubo wokwenyani welatex.
Ngapha koko, i-latex powder enokuphinda ihlakazwe ngokwayo ayincangathi, yenziwa ngokutshiza kokumiswa kwe-polymer emulsion.yomgubo.
Xa i-polymer powder edibeneyo ixutywe namanzi kwaye i-emulsified kwakhona, ineempawu ezifanayo njenge-emulsion yokuqala, oko kukuthi, ukufuma.
Iifilimu ezenziwe emva kokuvela kwamanzi ziguquguquka kakhulu kwaye zibambelela kakuhle kwii-substrates ezahlukeneyo.
Inokuphucula nokugcinwa kwamanzi kwizinto eziphathekayo kunye nokuthintela udaka lwesamente ukuba lube lukhuni, lome kunye nokuqhekeka ngokukhawuleza;
Ukwandisa iplastiki yodaka kunye nokuphucula ukusebenza kokwakhiwa.Ukuba uvavanyo luza kwenziwa, kufuneka lulungelelane
Yenza uvavanyo lodaka kwakhona ukuze ubone ukusasazeka kwayo, ukubunjwa kwefilimu, ukuguquguquka (kubandakanya uvavanyo lokukhupha,
Ingaba amandla okuqala afanelekile) Ngokubanzi, iziphumo zovavanyo zingafumaneka emva kweentsuku ze-10
