Umsebenzi we-latex powder enokuphinda ihlakazwe:
1. I-latex powder ehlakazekayo yenza ifilimu kwaye isebenze njenge-adhesive ukunyusa amandla ayo;
2. I-colloid ekhuselayo ixutywe yinkqubo yodaka (ayiyi konakala ngamanzi emva kokubunjwa kwefilimu, okanye "i-dispersion yesibili";
3. I-resin ye-polymer eyenza ifilimu isasazwa njengento yokuqinisa kulo lonke inkqubo yodaka, ngaloo ndlela ikhulisa ukudibanisa komdaka; Redispersible emulsion powder luhlobo lwe-adhesive powder eyenziwe nge-lotion (i-polymer ephezulu ye-molecular) emva kokumisa isitshizi. Emva kokunxibelelana namanzi, le powder inokusasazwa ngokukhawuleza ukwenza i-lotion, kwaye ineepropati ezifanayo njenge-lotion yokuqala, oko kukuthi, amanzi angenza ifilimu emva kokuphuma komphunga. Le filimu inokuguquguquka okuphezulu, ukuchasana kwemozulu ephezulu kunye nokunamathela okuphezulu kwii-substrates ezahlukeneyo.
Indima ye-latex powder enokuphinda ihlakazwe:
Ukuphucula ukuxhathisa impembelelo
Redispersible latex powder, eyi-resin thermoplastic. Ifilimu ethambileyo ehlanganiswe phezu kweengqungquthela zodaka, ezinokuthatha impembelelo yamandla angaphandle, ziphumle ngaphandle komonakalo, ngaloo ndlela ziphucula ukuchasana kwempembelelo yodaka.
Ukuphucula ukumelana nokunxiba kunye nokuqina
Ukongeza i-latex powder enokuphinda ikwazi ukunyusa ikhonkco elixineneyo phakathi kwamasuntswana odaka lwesamente kunye neefilimu zepolymer. Ukongezwa kwamandla okuncamathelisa ngokuhambelanayo kuphucula amandla odaka ukuze umelane noxinzelelo lokucheba, kunciphisa izinga lokunxiba, kuphucula ukuxhathisa ukunxiba, kunye nokwandisa ubomi benkonzo yodaka.
Ukuphucula i-hydrophobicity kunye nokunciphisa ukufunxa kwamanzi
Ukongeza i-latex powder enokuphinda ihlaziywe inokuphucula i-microstructure yodaka lwesamente. Ipolymer yayo yenza inethiwekhi engenakuguqulwa kwinkqubo ye-cement hydration, itywina i-capillary kwi-gel ye-samente, ivimbela ukungena kwamanzi, kwaye iphucula ukungaphumeleli.
Ukuphucula amandla okudibanisa kunye nokuhambelana
I-latex powder ephinda iphindwe kwakhona inempembelelo ebalulekileyo ekuphuculeni amandla okudibanisa kunye nokudibanisa kwezinto. Ngenxa yokungena kwe-polymer particles kwi-pores kunye ne-capillaries ye-matrix ye-cement, yenza ukubambisana okuhle emva kokuxutywa kunye ne-samente. Ukuncamathela okugqwesileyo kwe-polymer resin ngokwayo kuphucula ukubambelela kweemveliso zodaka lwesamente kwi-substrates, ngokukodwa ukubambelela kakubi kwezibophelelo ze-inorganic ezifana ne-samente kwii-substrates eziphilayo ezifana nemithi, i-fiber, i-PVC, kunye ne-EPS, Isiphumo sicacile.
Ukuphucula ukuzinza komkhenkce kunye nokuthintela ngokufanelekileyo ukuqhekeka kwezinto
I-latex powder ekwazi ukuphinda iphindwe kwakhona kunye ne-thermoplastic resin yayo inokuwoyisa umonakalo wokwandiswa kwe-Thermal yodaka lwesamente olubangelwa ngumahluko weqondo lokushisa. Ukoyisa iimpawu ze-deformation enkulu eyomileyo ye-shrinkage kunye nokuqhekeka okulula kodaka lwe-samente olucocekileyo lunokwenza izinto eziguquguqukayo, ngaloo ndlela kuphuculwe ukuzinza kwexesha elide lezinto eziphathekayo.
Ukuphucula ukugoba kunye nokuxhathisa
Kwisakhelo esiqinileyo esakhiwe yi-hydration ye-cement mortar, i-membrane ye-polymer i-elastic kwaye iguquguqukayo, idlala umsebenzi ofanayo njengento ehambayo phakathi kweengqungquthela ze-sement mortar. Iyakwazi ukumelana nemithwalo ephezulu yokuguqulwa, ukunciphisa uxinzelelo, kunye nokuphucula ukunyanzeliswa kunye nokugoba ukugoba.
Izinto eziluncedo kwi-latex powder ephinda ihlakazwe
Akukho mfuneko yokugcina nokuthutha ngamanzi, ukunciphisa iindleko zokuthutha; Ixesha elide lokugcina, i-anti-freezing, kulula ukuyigcina; Ipakethe incinci ngobukhulu, ilula ngobunzima, kwaye kulula ukuyisebenzisa; Inokuxutywa kunye ne-binder-based binder ukwenza i-synthetic resin modified premix. Xa isetyenziswe, amanzi kuphela kufuneka afakwe, angagcini nje ukuphepha iimpazamo ngexesha lokuxuba kwisayithi, kodwa aphucula ukhuseleko lokuphathwa kwemveliso.
