Rashin daidaituwa polymer foda (RDP)Abun da aka yi da kayan abinci ne da aka yi ta bushe polymer emulsion emulsion, wanda aka saba amfani dashi a cikin kayan da aka saba amfani da shi a cikin kayan, mayaka, adheresives adhereves. Babban aikinta shine ya koma cikin emulsion ta ƙara ruwa, samar da kyakkyawan m, elelitity, juriya na ruwa, crack juriya, da juriya na ruwa, da juriya na ruwa.
Za'a iya bincika foda na polymer foda (RDP) ana iya bincika shi daga bangarori da yawa, har da abubuwan haɗin:
1. Gudun Polymer
Babban kayan polymer foda ne polymer foda, wanda yawanci ana samun polymer da aka samo ta emulsion polymerization. Usermer gama gari ya ƙunshi:
Polyvinyl barasa (PVA): Yana da kyakkyawan m da kayan aikin fim kuma ana amfani dashi cikin kayan gini.
Polyacryles (kamar su polyacrylate, polyurthanes, da sauransu): suna da kyakkyawan elasticity, haɗin ƙarfi, da juriya ruwa.
Polystyrene (PS) ko Ethylene-Vinyl Acetate copolymer (Eva): Amfani da shi don inganta kaddarorin samar da fim, da juriya na ruwa, da juriya na ruwa.
Polymeth metharryate (PMMA): Wannan polymer yana da ingantaccen anti-tsufa da nuna gaskiya.
Wadannan polymer suna gyara emulsions ta hanyar halayen polymerization, sannan ruwan a cikin emulsion an samo shi ta bushewar polymer ko daskararre foda na polymer foda.
2. Surfacts
Don kula da kwanciyar hankali tsakanin barbashi polymer kuma guje wa agglomeration a cikin foda, za a ƙara yawan adadin surfactants a lokacin aiwatar samarwa. Matsayin Surfactants shine a rage tashin hankali na tsakanin barbashi da taimako da barbashi watse cikin ruwa. Surfacts na kowa sun haɗa da:
Surfacts ɗin da ba shi da kyau (kamar su polyethers, polyethylene glycols, da sauransu).
Anionic surfactants (kamar kitse acid salts, Alkyl sulfonates, da sauransu).
Wadannan surfactants na iya haɓaka watsawa na polymer foda (RDP) s, ba da damar marigayi foda don sake samar da emulsion bayan ƙara ruwa.
3. Talla da thickeners
Don daidaita aikin na Moryx powders da rage farashi, wasu masu talla a yayin samarwa. Akwai nau'ikan masu flers da yawa, da kuma waɗanda suka haɗa da su:
Calcium Carbonate: Fuskantar Inorganic mai narkewa wanda zai iya ƙara tasirin ingshi da inganta farashi mai tsada.
Talc: Zai iya ƙara yawan ruwa da juriya na kayan.
Ma'adinan siliki: kamar na Bentonite: kamar Bentonite, da kuma fadada hoto, da dai sauransu, na iya haɓaka juriya da juriya da ruwa na kayan.
Yawancin lokaci ana amfani da thicken don daidaita danko na samfurin don daidaita shi ga yanayi daban-daban. Abubuwa na kowa sun hada da Hydroxypropyl methylcellulhin (hpmc) da polyvinyl barasa (PVA).
4. Wakilin anti-cakina
A cikin samfuran powdered, don hana agglomerations yayin ajiya da sufuri, ana iya ƙara wakilan anti-CINTA yayin aiwatar da samarwa. Agret na anti-cing galibi wasu abubuwa masu kyau ne, kamar suilum silate, silicon dioxide, da sauransu foda barbashi daga saman marixar foda tare da hana barbashi daga agglomate tare.
5. Sauran ƙari
Rayayyun polymer foda (RDP) Mayu kuma yana iya ƙunsar wasu ƙari na musamman don inganta takamaiman kaddarorin:
Wakilin UV-resistant: Inganta juriya da yanayin yanayi da kuma ikon anti-tsufa na kayan.
Wakilin kwayar cuta: Yana rage haɓakar ƙananan ƙananan ƙwayoyin cuta, musamman idan ana amfani dashi a cikin yanayin da aka yi amfani da shi.
Plaster: Yana inganta sassauci da juriya na marigayi foda.
Magani: Hana kayan daga daskarewa a cikin yanayin ƙananan yanayin zafi, rinjayar gini da amfani da sakamako.
6. Danshi
Duk da cewa an warware shi polymer foda (RDP) yana cikin bushewar foda, shima yana buƙatar wani adadin danshi iko a lokacin aiwatar da kaya a ƙasa 1%. Abubuwan danshi da ya dace yana taimakawa wajen kula da hasken da hasken ruwa na dogon lokaci na foda.
Matsayi da aikin maimaitawa polymer foda (RDP)
Babban mahimmancin polymer foda (RDP) shine za a iya juyawa shi don samar da emulsion bayan ƙara halaye, kuma yana da waɗannan mahimman bayanai:
Kyakkyawan adonci: haɓaka karfin kayan sutturar gashi da adhereves, da inganta ƙarfin haɗin tsakanin kayan gini.
Elasticiti da sassauci: inganta elatingticity na shafi, haɓaka ƙarfin juriya da tasiri.
Juriya na Ruwa: Inganta tsayayya da ruwa na kayan, wanda ya dace da amfani a cikin waje ko yanayin laima.
Yanayin Designance: Inganta kayan UV, anti-tsufa da sauran kaddarorin, kuma mika rayuwar sabis.
Cowrowanci: Yana da kyakkyawar juriya kuma ya dace da bukatun anti-fatattaka a cikin ayyukan ginin.
RDPan yi ta hanyar canzawa polymer polymer cikin foda ta hanyar tsari mai saurin aiki. Yana da kyakkyawan kaddarorin kuma ana amfani dashi sosai a cikin gini, coftings, adheres da sauran filayen. Zabi da kuma yawan kayan aikinta kai tsaye yana shafar wasan karshe na.
