Uhlalutyo lweePropati kunye neziphumo zeLatex Powder eDispersible

Imveliso ye-latex ye-powder powder edibeneyo yi-powder-soluble redispersible powder, eyi-copolymer ye-ethylene kunye ne-vinyl acetate, kwaye isebenzisa i-polyvinyl alcohol njenge-colloid ekhuselayo.Ngenxa yomthamo ophezulu wokubopha kunye neempawu ezikhethekileyo zepolymer powders eziphinda ziphindwe, ezifana: ukunganyangeki kwamanzi, ukwakhiwa kunye nokufudumala ukushisa, njl., uluhlu lwabo lokusetyenziswa lubanzi kakhulu.

Redispersible latex powder isetyenziswa ikakhulu ku: ngaphakathi nangaphandle eludongeni putty umgubo, ithayile encamathelayo, ithayile arhente yokukhomba, ujongano lwe-agent eyomileyo yomgubo, udaka lwangaphandle lokugquma eludongeni, udaka lokuzilinganisa, udaka lokulungisa, udaka lokuhombisa, udaka olungangeni manzi, njl. xuba udaka.i

I-latex powder i-redispersible iluhlaza, indalo engqongileyo, igcina amandla okwakhiwa, umgangatho ophezulu wezinto ezininzi zokwakha i-powder, kwaye iyimfuneko ebalulekileyo kunye neyongezelelweyo esebenzayo yodaka oluxubileyo.Inokuphucula ukusebenza kodaka, ukunyusa amandla omdaka, ukuphucula amandla okubambisana phakathi kodaka kunye ne-substrates eyahlukeneyo, ukuphucula ukuguquguquka kunye nokusebenza, amandla okunyamezela, amandla okuguquguquka, ukuxhatshazwa kokugqoka, ukuqina, ukunamathela kwi-relay yodaka kunye nokugcinwa kwamanzi, ukwakheka.Ukongeza, i-hydrophobic latex powder inokwenza udaka lungangeni manzi kakhulu.

Indima ye-latex powder enokuphinda ihlakazwe:

1. Emva kokusabalalisa, i-latex powder edibeneyo yenza ifilimu kwaye isebenze njenge-adhesive yesibini yokuphucula umphumo;

2. I-colloid ekhuselayo ixutywa yinkqubo yodaka (ayiyi kutshatyalaliswa ngamanzi emva kokubunjwa kwefilimu, okanye "i-dispersion yesibili";

3. I-resin ye-polymer eyenza ifilimu isasazwa kuyo yonke inkqubo yodaka njengento yokuqinisa, ngaloo ndlela ikwandisa ukudibanisa komdaka;i-latex powder ehlaziywayo luhlobo lwe-emulsion ekhethekileyo eyomisiweyo (i-polymer) eyenziwe iPowder binder.Le powder inokusasaza ngokukhawuleza ukwenza i-emulsion emva kokudibanisa namanzi, kwaye ineempawu ezifanayo njenge-emulsion yokuqala, oko kukuthi, ifilimu inokuqulunqwa emva kokuba amanzi aphuke.Le filimu inokuguquguquka okuphezulu, ukuchasana kwemozulu ephezulu kunye nokuchasana neentlobo ezahlukeneyo zokubambelela kwi-substrates.
