Imboni yezokwakha ihlezi ishintsha futhi kuthuthukiswa izinto ezintsha nobuchwepheshe ukuze kube ngcono nakakhulu.Enye yezinto ezintsha ezinjalo ukusetshenziswa kwezimpushana ze-polymer ezihlakazeka kabusha emikhiqizweni yodaka lwe-polymer.Izimpushana ze-polymer ezihlakazeka kabusha zisetshenziswa njengezibophezelo ekwenzeni le mikhiqizo.Kuyimpuphu emhlophe etholwe yi-emulsion polymerization yama-monomers.Impushana ibe isicutshungulwa ibe yipolymer engaphinde ihlakazwe kalula emanzini.Izimpushana ze-polymer ezihlakazeka kabusha zinezakhiwo ezihlukahlukene ezizenza zibe izibophezelo ezifanele zemikhiqizo yodaka lwe-polymer.Kulesi sihloko, sihlola indima yempushana ye-polymer ehlakazekayo emikhiqizweni yodaka lwe-polymer nokuthi kungani idinga ukuguquguquka okuphezulu.
Izakhiwo ze-latex powder ehlakazeka kabusha
Izimpushana ze-polymer ezihlakazeka kabusha zinezakhiwo ezimbalwa ezizenza zifanelekele ukusetshenziswa emikhiqizweni yodaka lwe-polymer.Enye yezinto ezibalulekile zama-powders yikhono labo lokuthuthukisa ukunamathela komkhiqizo nokuguquguquka.Lokhu kungenxa yokuthi impushana yakhiwe ngezinhlayiya ze-polymer ezilengiswe emanzini.Lapho i-powder ixubene namanzi, yakha i-emulsion ezinzile engasetshenziswa kalula ezindaweni ezingaphansi kwe-substrate.Njengoba amanzi ehwamuka, izinhlayiya ze-polymer ziyanqwabelana ukuze zenze ifilimu eqhubekayo ehlanganisa umkhiqizo ne-substrate.
Enye impahla yama-polymer powders ahlakazekayo ukumelana kwawo namanzi.Impushana iyi-hydrophobic, okusho ukuthi ixosha amanzi.Lokhu kwenza imikhiqizo yodaka lwe-polymer imelane namanzi, ivimbele ukuthi ingaqhekeki futhi yonakale lapho ihlangana nomswakama.Lesi sakhiwo futhi senza imikhiqizo iqine kakhulu njengoba ikwazi ukumelana nokuchayeka isikhathi eside emanzini.
I-latex powder e-redispersible nayo inezindawo ezinhle kakhulu zokunamathela.Yakha isibopho esiqinile phakathi kodaka kanye ne-substrate, ithuthukisa ukusebenza okuphelele komkhiqizo.Lesi sakhiwo sibaluleke kakhulu emikhiqizweni ye-polymer mortar yezinhlelo zokusebenza zangaphandle njengoba idinga ukukwazi ukumelana nezimo zezulu ezinzima.
Kungani imikhiqizo ye-polymer mortar idinga ukuguquguquka okuphezulu
Imikhiqizo yodaka lwe-polymer equkethe izimpushana ze-polymer ezihlakazeka kabusha idinga ukuguquguquka okuphezulu njengoba ivame ukusetshenziswa ezinhlelweni zangaphandle ezivezwe ezimeni ezahlukahlukene zemvelo.Lezi zimo zingabangela i-substrate ukuthi inwebeke futhi inciphe, okuholela ekuqhekekeni nokonakala komkhiqizo.Ngakho-ke, ukuguquguquka okuphezulu kuyadingeka ukuze kuqinisekiswe ukuthi umkhiqizo ungamelana nalawa mandla ngaphandle kokuqhekeka noma ukuphuka.
Imikhiqizo ye-polymer mortar equkethe izimpushana ze-polymer ezihlakazeka kabusha nazo ziyasetshenziswa ezinhlelweni zangaphakathi ezivezwe ukudlidliza nokushaqeka.Kulezi zimo, ukuguquguquka okuphezulu kuyadingeka ukuze kuqinisekiswe ukuthi umkhiqizo ungamelana nalawa mandla ngaphandle kokuqhekeka noma ukuqhekeka.Ukuguquguquka okuphezulu nakho kunomthelela ekusebenzeni okuphelele komkhiqizo njengoba kuvumela ukuthi uhambisane ne-substrate futhi ugcine amandla awo esibopho ngaphansi kwengcindezi.
I-latex powder e-redispersible iyingxenye ebalulekile ekukhiqizeni imikhiqizo ye-polymer mortar.Izakhiwo zayo ezihlukahlukene ziyenza ibe ingcina efanelekile yale mikhiqizo, njengoba ithuthukisa izici zayo zokubopha, ikhulise ukumelana namanzi, futhi ithuthukise ukuqina kwayo kukonke.Imikhiqizo ye-polymer mortar equkethe izimpushana ze-polymer ezihlakazeka kabusha idinga ukuguquguquka okuphezulu, ikakhulukazi izinhlelo zokusebenza zangaphandle ezivezwe ezimeni ezahlukahlukene zemvelo kanye nezinhlelo zangaphakathi ezivezwe ukudlidliza nokushaqeka.Ngezinzuzo zabo eziningi, izimpushana ze-polymer ezihlakazekayo zishintsha ubuso bemboni yezokwakha ngokushintsha indlela izinto zokwakha ezikhiqizwa ngayo, okuholela emikhiqizweni esebenza kahle futhi ehlala isikhathi eside.
