I-polymer powder Redispersible (RDP) yinto eyongeziweyo yokwakha eguqula i-emulsion ye-polymer ibe yifomu yomgubo ngokusebenzisa inkqubo yokumisa isitshizi. Xa le powder ixutywe namanzi, inokusasazwa kwakhona ukuze yenze i-latex suspension ezinzileyo ebonisa iimpawu ezifana ne-latex yasekuqaleni. Esi sixhobo sisetyenziswe ngokubanzi kwishishini lokwakha, ngokukodwa ekuqulunqweni kodaka olomileyo kunye ne-adhesives yokwakha.
1. Izithako ezisisiseko kunye nenkqubo yokulungiselela
Izithako ezisisiseko ze-latex powder ezihlaziywayo zihlala zibandakanya i-polymer matrix, i-colloid ekhuselayo (efana ne-polyvinyl alcohol), izongezo (ezifana ne-defoamers kunye ne-plasticizers) kunye nezinye iifayili ze-inorganic (ezifana ne-calcium carbonate). I-polymer matrix yeyona nto iphambili ye-latex powder enokuphinda ihlakazwe. Iipolymers eziqhelekileyo ziquka i-ethylene-vinyl acetate copolymer (EVA), i-acrylate copolymer kunye ne-styrene-butadiene copolymer.
Inkqubo yokulungiselela umgubo welatex odispersible ikakhulu ibandakanya la manyathelo alandelayo:
I-Emulsion polymerization: Okokuqala, lungiselela i-emulsion enamanzi equkethe i-polymer. Ngokusebenzisa itekhnoloji ye-emulsion polymerization, ii-monomers zenziwe nge-polymerized emanzini ukwenza amasuntswana e-emulsion-efana ne-polymer.
Ukutshiza ukomisa: I-emulsion ye-polymer elungiselelwe yomiswa ngesomisi sokutshiza. I-emulsion ifafazwe ngamaconsi amahle kwaye yomiswe ngokukhawuleza ukuze yenze iincinci zepolymer powder.
Ukunyangwa kwendawo: Ngexesha okanye emva kwenkqubo yokumisa, ezinye ii-arhente zonyango (ezifana ne-polyvinyl alcohol) zivame ukudibaniswa ukuze kuphuculwe ukuzinza kunye nokuphinda kuhlaziywe umgubo.
2. Iimpawu zokusebenza
I-latex powder ephinda ikwazi ukuphinda iphindwe ineempawu ezininzi ezizodwa ezenza idume kwizicelo zokwakha:
I-Redispersibility: Le powder ingaphinda ihlakazwe emanzini kwaye ibuyiselwe kwisimo se-emulsion, inike izinto eziphathekayo ezifana ne-emulsion yasekuqaleni.
Ukubambelela okuphuculweyo: Kwingxube eyomileyo edibeneyo okanye i-adhesive, i-latex powder inokuphucula ukudibanisa phakathi kwezinto kunye ne-substrate.
Ukuguquguquka okuphuculweyo: Kunokuphucula ukuguquguquka kunye nokuxhatshazwa kwezinto eziphathekayo kunye nokunciphisa umngcipheko wokuqhekeka okubangelwa ukuxinwa koxinzelelo okanye utshintsho lweqondo lokushisa.
Ukumelana namanzi kunye nokumelana nemozulu: Umgubo we-latex owenziwe kwakhona unokuphucula ukuxhathisa kwamanzi kunye nokumelana nemozulu yezixhobo, kubenze bazinze ngakumbi kwiimeko zemozulu ezifumileyo okanye eziguqukayo.
Ukuyakha ngokulula: Izixhobo ezinomgubo we-latex odityanisiweyo wongeziweyo zinokusebenza ngcono ngexesha lokwakha, njengexesha elide elivulekileyo kunye nomgangatho ongcono.
3. Iindawo zokufaka izicelo
Redispersible latex powder inoluhlu olubanzi lwezicelo kushishino lokwakha, ingakumbi kubandakanywa le miba ilandelayo:
I-adhesive ye-tile: I-Latex powder inokuphucula kakhulu amandla okudibanisa kunye nokuguquguquka kwe-adhesives ye-tile, kwaye ifanelekile kwii-substrates ezahlukeneyo kunye neentlobo zeetayile, ngokukodwa kwimigangatho ye-geothermal kunye neenkqubo zodonga lwangaphandle.
Udaka olungangenwa ngamanzi: Kwifomula yodaka olungangeni manzi, umgubo welatex unokomeleza ukuxhathisa kokuqhekeka kunye nokusebenza kodaka lokungangeni kwamanzi, oko kuyenza isebenze kakuhle kwindawo efumileyo njengezindlu zokuhlambela kunye namakhitshi.
Izixhobo zomgangatho ozimele: I-Latex powder inokuphucula ukumanzi kunye nokunyuka kwezinto eziphantsi, ukuqinisekisa ukuba umgangatho ulungile, unamandla kwaye akukho lula ukuqhekeka emva kokwakhiwa.
Inkqubo yokugquma iindonga zangaphandle: Kwiinkqubo zokugquma iindonga zangaphandle (ezifana nodonga lwangaphandle kunye neenkqubo zangaphakathi zokugquma), i-latex powder inokuphucula amandla okudibanisa phakathi kwebhodi yokudibanisa kunye nesiseko sesiseko, ukuqinisekisa ukunyaniseka kunye nokuqina kwenkqubo yokugquma.
Udaka lokulungiswa: I-Latex powder idlala indima ekuphuculeni i-bonding kunye nokuxhatshazwa kwe-crack kwi-mortar yokulungisa, ukuqinisekisa ukudibanisa okulungileyo kwendawo yokulungisa kunye nesakhiwo sokuqala kunye nokwandisa ubomi benkonzo yesakhiwo.
4. Ukhuseleko lokusingqongileyo kunye nozinzo
Ngokuphuculwa kolwazi lokusingqongileyo, iimpawu zokukhuselwa kokusingqongileyo ze-latex powder eziphinda zihlaziywe nazo ziye zaqwalaselwa. Abavelisi abaninzi bamkela iinkqubo zokuvelisa ezihambelana nokusingqongileyo ukunciphisa ukusetyenziswa kwezinto ezinobungozi, kwaye le nto inokunciphisa inkunkuma kunye nokuphucula ukusetyenziswa kwezixhobo zokusebenza kwizicelo zokwakha. Ukongezelela, ngelixa uphucula ukusebenza kwezinto zokwakha, i-latex powder inokunciphisa iindleko zokugcina kunye nokusetyenziswa kwamandla kwezakhiwo, ngaloo ndlela igalelo ekuphuhliseni izakhiwo ezizinzileyo.
5. Amathuba emarike kunye neendlela zophuhliso
Ngokunyuka kwemfuno yokusebenza okuphezulu kunye nezixhobo ezihambelana nokusingqongileyo kushishino lokwakha, amathemba emarike yomgubo we-latex onokuphinda ahlakazwe abanzi. Iindlela zophuhliso lwexesha elizayo ziquka:
Ukulungiswa kokusebenza: Ukuphucula ngokuqhubekayo ukusebenza kwe-latex powder, njengokuphucula ukuchasana kwemozulu kunye nokuchasana kweekhemikhali, ukuhlangabezana neemfuno zeemeko ezahlukeneyo zesicelo.
Imveliso eluhlaza: Ukunciphisa i-carbon footprint kunye nefuthe lendalo yenkqubo yokuvelisa ngokusebenzisa i-chemistry eluhlaza kunye neenkqubo ezizinzileyo.
Iimveliso ezenziwe ngokwezifiso: Ukubonelela ngeemveliso ze-latex zomgubo ngokweemfuno ezithile zabathengi ukuziqhelanisa nemeko yesicelo esikhethekileyo, njengokwakhiwa kobushushu obuphantsi, ubume obunomswakama ophezulu, njl.
I-latex powder edibeneyo, njenge-addispersible material yokongeza, inoluhlu olubanzi lwamathemba okusebenza. Ukusebenza kwayo okugqwesileyo akuphuculi nje kuphela umgangatho wezinto zokwakha, kodwa kwakhona kukhuthaza ishishini lokwakha ukuba liphuhlise ngendlela ehambelana nokusingqongileyo kunye nesikhokelo esizinzileyo.
