II-RDP powderiyancibilika emanziniimpushana ehlakazeka kabusha, okuyi-copolymer ye-ethylene ne-vinyl acetate, futhi isebenzisa utshwala be-polyvinyl njenge-colloid evikelayo. Ngenxa yekhono eliphezulu lokubopha kanye nezakhiwo eziyingqayizivele zempushana ye-latex ehlakazeka kabusha, njengokumelana namanzi, ukusebenza kahle, kanye nokufakwa kwe-thermal, ububanzi bokusebenza kwabo bubanzi kakhulu. Redispersible latex powder isetshenziswa kakhulu odakeni oluxubile olomile olufana ne-putty powder yezindonga zangaphakathi nangaphandle, i-ceramic tile bonding ejenti, i-ejenti yokukhomba amathayela e-ceramic, i-ejenti yokusebenzelana kwempushana eyomile, udaka lwangaphandle olufaka udonga, udaka oluzilinganisa, udaka lokulungisa, udaka lokuhlobisa. , udaka olungangeni manzi, njll. Impushana ye-latex ephindwe kabusha iluhlaza, ivumelana nemvelo, yonga amandla, ikhwalithi ephezulu kanye nezinto ezihlukahlukene zokwakha impushana, futhi iyisengezo esisebenzayo esibalulekile sodaka olomile oluxubile. Ingakwazi ukuthuthukisa ukusebenza kodaka, ikhulise amandla ayo, ithuthukise amandla okubopha phakathi kodaka nama-substrates ahlukahlukene, ithuthukise ukuguquguquka nokuguquguquka, amandla acindezelayo, amandla aguquguqukayo, ukumelana nokugqokwa, ukuqina, ukunamathela namandla okugcina amanzi, nokwakhiwa kodaka. Ngaphezu kwalokho, i-latex powder ene-hydrophobicity ingenza udaka lube nezindawo ezinhle zokungangeni manzi.
Indima yei-latex powder ehlakazeka kabusha:
1. II-EVA copolymeryakha ifilimu ngemuva kokuhlakazwa futhi isebenza njenge-adhesive yesibili yokuthuthukisa amandla ayo;
2. I-colloid evikelayo imuncwa uhlelo lodaka (ngeke lonakaliswe amanzi ngemva kokwakhiwa kwefilimu, noma "ukuhlakazeka kwesibili";
3. I-resin ye-polymer eyenza ifilimu isakazwa njengento yokuqinisa kulo lonke uhlelo lodaka, ngaleyo ndlela ikhulise ukuhlangana kodaka; I-redispersible emulsion powder iwuhlobo lokunamathela okuyimpushana olwenziwa yi-lotion ekhethekile (i-polymer ephezulu) ngemva kokumiswa kwesifutho. Ngemva kokuthintana namanzi, le mpushana ingaphinde ihlakazwe ngokushesha ukuze yenze isithako, futhi inezakhiwo ezifanayo nelotion yokuqala, okungukuthi, amanzi angenza ifilimu ngemva kokuhwamuka. Le filimu inokuguquguquka okuphezulu, ukumelana nesimo sezulu esiphezulu nokunamathela okuphezulu kuma-substrates ahlukahlukene.
Umsebenzi kanye nokusetshenziswa kwe-Redispersible Latex Powder
I-redispersible emulsion powder iwuhlobo lwe-powder adhesive eyenziwe nge-lotion ekhethekile (i-polymer ephezulu) ngemva kokumiswa kwesifutho. Ngemva kokuthintana namanzi, le mpushana ingaphinde ihlakazwe ngokushesha ukuze yenze isithako, futhi inezakhiwo ezifanayo nelotion yokuqala, okungukuthi, amanzi angenza ifilimu ngemva kokuhwamuka. Le filimu inokuguquguquka okuphezulu, ukumelana nesimo sezulu esiphezulu nokunamathela okuphezulu kuma-substrates ahlukahlukene.
Inani eliphakeme kakhulu lama-RDPiyimpahla yokwakha eluhlaza, evumelana nemvelo, ewonga amandla, esezingeni eliphezulu futhi eguquguqukayo, futhi iyisengezo esisebenzayo esibalulekile sodaka olomile oluxubile. Ingakwazi ukuthuthukisa ukusebenza kodaka, ikhulise amandla ayo, ithuthukise amandla okubopha phakathi kodaka nama-substrates ahlukahlukene, ithuthukise ukuguquguquka nokuguquguquka, amandla acindezelayo, amandla aguquguqukayo, ukumelana nokugqokwa, ukuqina, ukunamathela namandla okugcina amanzi, nokwakhiwa kodaka. Ngaphezu kwalokho, i-latex powder ene-hydrophobicity ingenza udaka lube nezindawo ezinhle zokungangeni manzi.
Impushana ye-latex ehlakazeka kabushaisetshenziswa kakhulu odakeni oluxubekile oluhlukahlukene olufana ne-putty powder yezindonga zangaphakathi nezangaphandle, i-ejenti yokubopha amathayela e-ceramic, i-ejenti yokukhomba amathayela e-ceramic, i-ejenti yokuxhumana yempushana eyomile, i-ejenti yokufakwa odongeni yangaphandle, udaka lokuzilinganisa, udaka lokulungisa, udaka lokuhlobisa, udaka olungangeni manzi. , njll.
Ububanzi bokusetshenziswa
1. Ukufakwa odongeni kwangaphandle nodaka lokuplasta
2. I-ejenti yokukhomba i-Ceramic tile
3. I-putty eguquguqukayo yezindonga zangaphandle
Lo mkhiqizo uyimpushana ye-latex ethambile engahlakazeka emanzini, ithuthukise ukunamathela phakathi kodaka nezisekelo ezijwayelekile, ithuthukise izakhiwo zemishini yodaka, futhi ithuthukise ukwakheka kwayo.
