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.
Umsebenzi we-latex powder ehlakazeka kabusha: 1. Impushana ye-latex ehlakazekayo yakha ifilimu futhi isebenza njengento enamathelayo ukuze ithuthukise amandla ayo; 2. I-colloid evikelayo imuncwa uhlelo lodaka (ngeke lonakaliswe amanzi ngemva kokwakhiwa kwefilimu, noma “ukuhlakazeka kwesibili”; 3...Funda kabanzi -
I-Solid hydroxypropyl methyl cellulose HPMC odakeni olumanzi
I-Soluble hydroxypropyl methyl cellulose (HPMC) iwuhlobo lwe-non-ionic cellulose ether, eyenziwe nge-polymer cellulose yemvelo ngochungechunge lokucutshungulwa kwamakhemikhali. I-Hypromellose (HPMC) iyimpushana emhlophe encibilika emanzini abandayo ukuze yakhe isixazululo esisobala, esibonakalayo. Inakho okufanele...Funda kabanzi -
