Ukumelana namanzi: Njenge-emulsion engangeni manzi, ukumelana namanzi yeyona nto iphambili neyona ibalulekileyo. Ngokubanzi, ii-emulsions ezinokumelana namanzi okuhle zinokugcina ifilimu yepeyinti icacile kwaye ingabi lula ukuyithambisa nokuba sele imanziswe emanzini ixesha elide. Ngokohlalutyo oluqhelekileyo lwembonakalo yomzimba, ukumelana namanzi kwe-emulsion yokukhanya okuluhlaza okwesibhakabhaka kungcono kunokwe-emulsion yokukhanya okumhlophe okanye okubomvu. Ngokubanzi, okukhona ubukhulu besuntswana buncinci, kokukhona ukumelana namanzi kungcono, kwaye ubungakanani besuntswana bunokugwetywa ngokubonakala. : Ulandelelwano lobungakanani besuntswana: olucacileyo > ukukhanya okuluhlaza okwesibhakabhaka > ukukhanya okuluhlaza > ukukhanya okubomvu > okumhlophe okumhlophe. l Ukwandiswa: Okukhona ukuphakama kokwandiswa, kokukhona ukuguquguquka kobushushu obuphantsi, kwaye kokukhona umlinganiselo wolwelo ukuya kumgubo uphezulu. Ke ngoko, ukuphakama kokwandiswa kwe-emulsion kuya kuba nokusebenza kakuhle kweendleko.

Ukuncamathelisa: I-emulsion elungileyo engangeni manzi kufuneka ibe nesiphumo esihle kakhulu sokunamathela kwisiseko sesamente. Ngokuqhelekileyo, eyona ndlela yendabuko kodwa isebenzayo kukufumana i-emulsion ezandleni zakho, uze uyivumele yome ngokwendalo. Kwelinye icala, isiphumo sokutsala se-emulsion siyajongwa. Ukuba kunzima ukuyihlikihla ezandleni zakho, kubonisa ukuba ukunamathela kwe-emulsion kungcono. Enye indlela kukuxuba i-emulsion nesamente, uze uyenze phezu kwethayile. , nto leyo ebonisa ukuba ukunamathela kwe-emulsion kuphantsi. Ukuba i-emulsion elungileyo ixutywe nesamente kwaye yomiswe, akukho lula ukuyiphosa phantsi.

Ukhuseleko lokusingqongileyo: Ii-emulsions ezingangeni manzi ze-polymer zonke zenziwa ngenkqubo ye-polymerization, ngoko ke izixhobo eziphambili kunye nokuzinza kwefomyula kuchaphazela ngokuthe ngqo ukusebenza kakuhle kwe-synthesis. Kwi-emulsions ezinokusebenza okuphantsi kwe-synthesis, umxholo we-monomer ekhululekileyo uya kuba phezulu ngokwemvelo, kwaye umxholo we-monomer ekhululekileyo uya kuba phezulu ngokwemvelo. Inobungozi. Okukhona inqanaba liphezulu, kokukhona iyingozi emzimbeni womntu. Ngokubanzi, umxholo wee-monomers ezikhululekileyo unokugwetywa ngevumba. Kwelinye icala, kulula ukuvelisa igesi ye-ammonia emva kokuba i-polymer engangeni manzi kunye nesamente zixutywe, nangona igesi ye-ammonia ingenabungozi kakhulu emzimbeni womntu. Nangona kunjalo, ukuba ulwakhiwo lwenziwa kwigumbi lokuhlambela elivaliweyo, i-basement kunye nezinye iindawo, ngenxa yomoya ongagudiyo, kulula ukubangela ukuba uxinzelelo lwegesi ye-ammonia kwindawo nganye lube phezulu kakhulu. Ukusebenza kwindawo enjalo ixesha elide kunokukhokelela ngokulula ekutshisweni kwe-mucosa yempumlo.

Ukumelana nemozulu: Ukumelana nemozulu kokungangeni manzi kwepolymer kungcono kunokwe-polyurethane kunye nerabha ye-styrene-butadiene. Ukumelana nemozulu kwe-acrylic emulsion kulungile, kodwa ixabiso liphezulu kakhulu kunele-styrene-acrylic emulsion. Umahluko phakathi kwe-styrene-acrylic polymer emulsion kunye ne-acrylic acid ngumahluko ekumelaneni nombala otyheli, kodwa kwizinto ezingangeni manzi, i-styrene-acrylic polymer isetyenziswa ngokubanzi njenge-Emulsion, ixabiso elifanelekileyo, ukumelana nemozulu elungileyo.
