As an important part of modern building materials, redispersible polymer powders (RDP) play an important role in many applications such as mortars, putties, grouts, tile adhesives and thermal insulation systems. Isakhono sokwenza ifilimu ye-RDP sisimo esibalulekileyo esichaphazela umgangatho wemveliso yokugqibela. Ukuhlaziywa kweepowders emva kokugcina, ezothutho kunye nokudibanisa kubalulekile. Yiyo le nto iindlela ezineenkcukacha nezingqongqo zibalulekile ukuqinisekisa ukufaneleka kunye nokusebenza kweemveliso ze-RDP.
Enye yezona mvavanyo zibalulekileyo ze-RDP yefilimu yefilimu yi-powder ye-powder ye-enulsion yefilimu yovavanyo lwefilim. Le ndlela yovavanyo isetyenziswa ngokubanzi kuvavanyo lwemveliso esemgangathweni kunye ne-R & D Inkqubo ye-RDP. Indlela yovavanyo lokwenza ifilimu ye-polymer ye-polymer ye-polymer yindlela elula nelula yovavanyo, enokuvavanya ngokufanelekileyo amandla efilimu yemveliso ye-RDP.
Okokuqala, ukuhlengahlengiswa komgubo kufuneka kuvavanywe ngaphambi kovavanyo lweefilimu. Ukuxuba umgubo wamanzi kwaye uvuselele ukuhlengahlengisa amasuntswana ePolymer aqinisekisa ukuba ipowder isebenza ngokwaneleyo kuvavanyo.
Emva koko, indlela yokufumana i-polymer ye-polymer yefilimu inokuqaliswa. Iqondo lobushushu elisetiweyo kunye nokufuma okuhambelana kufuneka kugcinwe imeko yezizwe kwifilimu ukunyanga ngokufanelekileyo. Izinto ezenziwa kubungakanani bomzimba ochazwe kwangaphambili. Izinto ezinzulu ziya kuxhomekeka kwiimfuno zesicelo. Umzekelo, isicelo sokulala sinokufuna i-corimentic. Emva kokutshiza, umbandela uvunyelwe ukuba wome ixesha elimisiweyo, emva kokuba amandla okwenza ifilimu anokuvavanywa.
I-powder ye-powder ye-Emolsion yeFowuni yeFillion yovavanyo lwefilimu ivavanya izinto ezininzi. Oku kubandakanya ukugqiba komphezulu, ukunamathela kunye nokuguquguquka kwefilimu. Ukugqitywa komphezulu kungavavanywa ngokuhlolwa okanye ukusebenzisa i-microscope. Umlinganiso wefilimu kwi-filthed kwi-subtate uzimisele ukusebenzisa uvavanyo lweteyiphu. I-adhesion eyaneleyo iboniswa xa ityhubhu isetyenziswa kwi-tepi kwaye ifilimu ihleli ilandelwa yi-supicterate emva kweteyiphu isusiwe. Ukuguquguquka kwefilimu kunokuvavanywa kusetyenziswa uvavanyo lweteyiphu. Yolula ifilimu ngaphambi kokuba isuswe iteyiphu, ukuba iyawalandelela ikhubalo, ibonisa inqanaba elifanelekileyo lokuguquguquka.
Kubalulekile ukulandela iinkqubo zovavanyo ezifanelekileyo zokuqinisekisa iziphumo ezingaguqukiyo. Iinkalo ezininzi zovavanyo lokwenza iifilimu kufuneka zibekwe emgangathweni ukuphelisa ukwahluka phakathi kweebatch ezahlukeneyo zovavanyo. Oku kubandakanya iinkqubo zokulungiselela, ubushushu, ubushushu, ubukhulu bemisebenzi kunye nexesha lokunyanga. Uvavanyo lweteyiphu kufuneka lwenziwe ngoxinzelelo olufanayo lokufumana iziphumo ezinokuthelekiswa. Ukongeza, izixhobo zovavanyo kufuneka zilungelelaniswe ngaphambi kovavanyo. Oku kuqinisekisa imilinganiselo echanekileyo nechazayo.
Ekugqibeleni, utoliko oluchanileyo lweziphumo zendlela yokuvavanywa kwefilimu ye-Emolsion ibalulekile. Iziphumo ezifunyenwe ziindlela zokuvavanya ifilimu kufuneka zithelekise imigangatho emiselweyo yesicelo esithile sezinto. Ukuba ifilimu ihlangabezana neemfuno kunye neenkcazo, umgangatho wayo uthathwa njengento yamkelekile. Ukuba akukhange kubenjalo, imveliso inokufuna ukucokiswa okungapheliyo okanye ukuguqulwa kokuphucula iipropathi zefilimu. Iziphumo zovavanyo zinokukunceda ekwenzeni iingxaki kunye nokuchonga imiba yemveliso okanye iziphene zemveliso.
Kwisishwankathelo, umgubo wokusasaza i-polymer pilemer yefilim idlala indima ebalulekileyo ekumiseleni ukusebenza kwemveliso yePolymer Polymer Polymer Polymer. Njengomnye wezinto ezibalulekileyo zezinto zokwakha zanamhlanje, amandla okwenza ifilimu ye-RDP ibalulekile kwintsebenzo yayo. Ukuqinisekisa ukuba i-RDP yefilimu yokwakha ifilimu ihlangabezana nepropathi oyifunayo kubalulekile ekuqhubeni intsebenzo kunye nobomi bemveliso yokugqibela. Ukubambelela ngokuchanekileyo kwiinkqubo zovavanyo kubalulekile ekufumaneni iziphumo ezingaguqukiyo. Ukutolikwa okufanelekileyo kweziphumo zovavanyo kunokubonelela ngokuqonda okuxabisekileyo kukuqulunqwa nokuveliswa kweemveliso ze-RDP ekumgangatho ophezulu.
