Isetshenziselwa ini i-emulsion powder ehlakazekayo?
Impushana ye-emulsion ehlakazeka kabusha ukuhlakazeka kwe-polymer lotion ngemuva kokumiswa kwesifutho. Ngokukhuthazwa nokusetshenziswa kwayo, ukusebenza kwezinto zokwakha zendabuko kuye kwathuthukiswa kakhulu, futhi amandla okubopha kanye nokuhlangana kwezinto kuye kwathuthukiswa. Ingathuthukisa i-perf...Funda kabanzi -
Yiziphi izithasiselo zokwakha ezingathuthukisa izakhiwo zodaka olomile oluxubile? Zisebenza kanjani?
I-anionic surfactant equkethwe ezithasiselweni zokwakha ingenza izinhlayiya zikasimende zihlakazeke zodwa ukuze amanzi amahhala ahlanganiswe yi-aggregate kasimende akhululwe, futhi iqoqo likasimende elihlanganisiwe lihlakazeke ngokuphelele futhi lifakwe amanzi ngokuphelele ukuze kuzuzwe isakhiwo esiminyene futhi...Funda kabanzi -
Chaza kabanzi ngenqubo yokuthuthukiswa komlando yempushana ye-latex ehlakazeka kabusha kanye ne-ceramic tile adhesive
Kusukela ngawo-1930s, izibophezelo ze-polymer zazisetshenziselwa ukuthuthukisa ukusebenza kodaka. Ngemuva kokuthi i-polymer lotion ibekwe ngempumelelo emakethe, u-Walker wasungula inqubo yokumisa isifutho, eyaqaphela ukuhlinzekwa kwesithambiso sempushana yerabha, kwaba ukuqala kwenkathi ...Funda kabanzi -
Impushana ye-latex edispersible iwuhlobo lokunamathela okuyimpushana olwenziwa ngokumiswa okukhethekile kwesifutho se-lotion.
Impushana ye-latex edispersible iwuhlobo lokunamathela okuyimpushana olwenziwa ngokumiswa okukhethekile kwesifutho se-lotion. Lolu hlobo lwempushana lungahlakazeka ngokushesha lube yi-lotion ngemva kokuxhumana namanzi, futhi lunezici ezifanayo njenge-lotion yokuqala, okungukuthi, amanzi angakha ifilimu ngemva kokuhwamuka. Le filimu ine...Funda kabanzi -
Iyini imisebenzi ye-polymer powder ehlakazeka kabusha emikhiqizweni ehlukene ye-drymix? Ingabe kuyadingeka ukwengeza impushana ehlakazeka kabusha odongeni lwakho?
I-polymer powder e-redispersible inezinhlobonhlobo zezinhlelo zokusebenza. Idlala indima ebonakalayo ezinhlelweni ezibanzi nezibanzi. Njengento enamathelayo yamathayela e-ceramic, i-wall putty kanye nodaka lokufakwa ngaphakathi kwezindonga zangaphandle, konke kunobudlelwane obuseduze nempushana ye-polymer ehlakazeka kabusha. Ukwengezwa kwe-redispersible la...Funda kabanzi -
Iqhaza nezinzuzo ze-latex powder ehlakazeka kabusha，Lokhu akugwemi kuphela amaphutha ngesikhathi sokuxuba endaweni yokwakha, kodwa futhi kuthuthukisa ukuphepha kokuphathwa komkhiqizo.
