Yini i-polymer polymer powders?

Ama-polymer powders (RPP) agelezayo, ama-powders amhlophe akhiqizwa yi-Spray-Spray Extemer dispressions noma ama-emulsions. Ziqukethe izinhlayiya ze-polymer ezihlanganiswe nama-ejenti abavikelayo nezithasiselo. Lapho kuxutshwa namanzi, la mapondo asabalalisa kalula ukwakha ama-emulser e-polymer, okwenza akwazi ukusetshenziswa kwawo ezinhlobonhlobo zezicelo ekwakhiweni, ukupenda kanye nokumboza, ukunamathela kanye nezinye izimboni.

Ukwakheka:

Ukwakheka kwama-polymer powders ahleliwe ngokuvamile kufaka phakathi izinto ezilandelayo:

1. Izinhlayiya ze-Polymer: Ingxenye eyinhloko ye-RPP yizinhlayiya ze-polymer, ezisuselwa kuma-polymers ahlukahlukene afana ne-vinyl acetate-ethylene (vae), i-acryrene acetate (eVA), noma i-polyvinyl acetate ( Pva). Lawa ma-polymers anikela ngezakhiwo ezifiselekayo kanye nezimpawu zokusebenza zomkhiqizo wokugcina.
2. Ama-ejenti avikelayo: Ukuvimbela izinhlayiya ze-polymer kusuka ku-agglwerating ngesikhathi sokugcina kanye nokuhamba, ama-ejenti okuvikela anjenge-polyvinyl alcohol (PVA) noma izipho ze-cellulose zivame ukusetshenziswa. Lawa ma-ejenti aqinisa izinhlayiya ze-polymer futhi aqinisekise ukubuyiselwa kwabo emanzini.
3. Amapulangwe: Amapulasitiki angangezwa ukuthuthukisa ukuguquguquka, ukusebenziseka kanye nokunamathela kwama-RPPs. Lezi zithangeluza zisiza ukwandisa ukusebenza kwezinhlayiya ze-polymer kuzicelo ezahlukahlukene, ikakhulukazi ezitsheni eziguqukayo, ukunamathela kanye nabenzaladi.
4. Ama-filler kanye nezithasiselo: Kuya ngezidingo ezithile zohlelo lokusebenza, ama-filler, imibala, ama-crosslinking agents, izinhlanzi, nezinye izengezo zingafakwa kwizakhi ze-RPP ukuthuthukisa impahla yazo noma zinikeze ukusebenza okuthile.

Izakhiwo Nezimpawu:

Ama-polymer polymer powders akhombisa izakhiwo ezimbalwa ezibalulekile nezimpawu ezibenza ziguquguquke futhi zisetshenziswe kabanzi kwizimboni ezahlukahlukene:

1. Ukuhlenga kabusha: I-RPP isatshalaliswa kalula emanzini ukwakha ama-emulmer noma ukuhlakazwa okuzinzile, okuvumela ukufakwa kalula kube ukwakheka kanye nohlelo oluzayo.
2. Ikhono elenziwa ngefilimu: Lapho ihlakazeka emanzini futhi isetshenziswa ezindaweni, i-RPP ingakha amafilimu amancanyana, aqhubekayo lapho eyomiswa. Lawa mafilimu athuthukisa ukunamathela, ukuqina, kanye nokumelana kwesimo sezulu ezitsheni, anamathela, kanye nabelwala.
3. Isikhangiso esithuthukisiwe: I-RPP Thuthukisa ukunamathela phakathi kwama-substrates kanye nokugqoka, izimbotshana, noma ukunamathela, okuholela ekusebenzeni okunamandla nasezintweni zokwakha.
4. Ukugcinwa kwamanzi: Imvelo ye-hydrophilic ye-RPP ibenza bakwazi ukudonsa futhi bagcine amanzi ngaphakathi kokuqamba, ukuthuthukisa i-hydration kanye nokwenza ngcono ukusebenziseka, isikhathi esivulekile, kanye nokunamathela kuzinhlelo zokusebenza ezinamathela ngodaka nasezindaweni ezinamathela.
5. Ukuvumelana nezimo nokuqina: Izinto zokwenziwa ze-RPP zibonisa ukuguquguquka okuguquguqukayo, ukuqina, kanye nobunzima, kubenza bamelane kakhulu ekuqhekekeni, ekulimaleni nasekulimaleni komthelela.
6. Ukumelana Nesimo Sezulu: Ama-RPPs athuthukise ukumelana nesimo sezulu kanye nokuqina kwezimbozo, ama-sealants, kanye nolwelwesi olunganambisene, ukuhlinzeka ngokuvikelwa okuhlala isikhathi eside, ukuhlinzeka ngemisebe ye-UV, umswakama, kanye nezici zezemvelo.

Izicelo:

Ama-polymer polymer powders athola izinhlelo zokusebenza ezinhlobonhlobo zezimboni nemikhiqizo, kufaka phakathi:

• Ukwakhiwa: Amathanga anamathela, udaka, ama-grouts, ama-membranes angangeni manzi, amakhompiyutha okuzenzela, kanye nokufakwa kwangaphandle kanye nezinhlelo zokuqeda (ama-EIFs).
• Amapende nezimbobo: upende wangaphandle, ukugqokwa okubekiwe, ama-plasters wokuhlobisa, kanye nezembatho zezakhiwo.
• Adhesives kanye nama-sealants: ama-tile anamathela, ama-crack filler, ama-caulks, ama-sealars aguquguqukayo, kanye nokunamathelisa okuzwela ingcindezi.
• Izindwangu: I-Textile Coatings, ama-ejenti wokuqeda, kanye nama-compounds.

Ama-polymer powders anhlobonhlobo futhi angasebenzi asetshenziselwa ukwenza ngcono ukusebenza, ukuqina, kanye nokuguquguquka kwemikhiqizo ehlukahlukene nokwakha ekwakheni, ukupenda kanye nokumboza, ukunamathela, izindwangu, kanye nezinye izimboni.
