Redispersible polymer powder (RDP) chinhu chakakosha chepolymer chinowedzera chinoshandiswa kusimudzira kushanda kwesimende-based, gypsum-based, lime-based uye lime-mortar-based materials. RDP inovandudza mashandiro akazara ezvishandiso izvi kuburikidza nekuita kwayo kwekubatana, kusimbaradza, kutsemuka kuramba, kuramba kwemvura, nezvimwewo, uye inoshandiswa zvakanyanya mukuvaka.
Mhando huru dzeRDP
Mhando dzeRDP dzinonyanya kuiswa zvichienderana nerudzi rwe substrate yavanoumbwa nayo, ndima yekushandisa uye maitiro anoshanda. Zvakajairwa RDPs zvinosanganisira zvinotevera:
Ethylene-vinyl acetate copolymer (EVA) mhando:
Zvimiro: Ethylene-vinyl acetate copolymer imwe yemhando dzakawanda dzeRDP. Iyo ine yakanakisa kuchinjika uye kunamatira, uye inopa yakanaka kudzivirira kwemvura uye kuramba kwemamiriro ekunze.
Chishandiso: Inonyanya kushandiswa mumatairi anonamira, ega-leveling pasi zvinhu, ekunze madziro ekudzivirira masisitimu uye mamwe minda.
Zvakanakira: Inopa kusimba kwakanaka uye kuchinjika, inokodzera zviitiko zvinoda kumwe kuchinjika uye kunamatira.
Zvakashata: Nekuda kwehuwandu hwayo hweethylene, mashandiro ayo anogona kunge asina kukwana zvishoma mune mamwe maapplication ane yakakwirira simba zvinodiwa.
Ethylene-vinyl acetate-vinyl acetate terpolymer (VeoVa/EVA) mhando:
Zvimiro: Rudzi urwu rweRDP runounza VeoVa (vinyl ester) pahwaro hwe ethylene uye vinyl acetate copolymerization, iyo inovandudza kudzivirira kwemvura uye kugadzikana kwemakemikari ezvinyorwa.
Chishandiso: Inowanzo shandiswa mune ekunze madziro machira uye gypsum zvigadzirwa, nezvimwe.
Zvakanakira: Iine mvura iri nani inodzivirira uye inodzivirira kemikari, inokodzera zvekunze uye zvemakemikari zvikumbiro.
Zvakaipa: Kuenzaniswa neyechinyakare EVA mhando, mutengo unogona kunge wakakwira zvishoma.
Styrene-butadiene copolymer (SB) mhando:
Zvimiro: Iyo inonyanya kuumbwa ne styrene uye butadiene monomers, uye ine yakanaka yekubatanidza zvivakwa, kuchinjika uye kudzivirira mvura.
Kushandisa: Inowanzo shandiswa mumatairi anonamira uye anochinjika putties.
Zvakanakira: Kubatana kwakanaka uye kuchinjika, uye zvakare kuita kwakanakisa mukudzivisa mvura.
Zvakashata: Inogona kukwegura pasi pechiedza che ultraviolet.
Vinyl acetate-ethylene copolymer (VAE) mhando:
Zvimiro: Iyo copolymer yevinyl acetate uye ethylene, ine yakanakisa kuchinjika uye kudzivirira mvura.
Chikumbiro: Inokodzera kunamatira mataira, ekunze madziro ekudzivirira masisitimu, gypsum-based self-leveling, nezvimwe.
Zvakanakira: Inopa kunamatira kwakanaka uye kuramba kwemvura, uye ine mamwe makemikari kuramba.
Zvakaipa: Mari yacho yakati wandei.
Acrylic copolymer (Acrylic) mhando:
Zvimiro: Chinhu chikuru ndeye acrylic ester, iyo ine yakanakisa adhesion uye kuchinjika.
Chikumbiro: Inoshandiswa zvakanyanya mukushongedza dhaka, mataira adhesives, gypsum uye zvimwe zvinhu.
Zvakanakira: Yakanakisa kunamatira uye kuchinjika, uye yakanakisa UV kuramba.
Zvakaipa: Nekuda kwemutengo wakakwira we acrylic zvinhu, mutengo werudzi urwu rweRDP zvakare wakakwira.
Mabasa uye mashandisirwo eRDP
Kuvandudza bonding performance:
RDP inotora bhiriji muzvinhu, inosimudzira kunamatira kwekunamira, uye inovandudza chisungo pakati pezvinhu zvekuvaka uye substrate.
Nzvimbo dzekushandisa dzinosanganisira mataira anonamira, bonding mortars, nezvimwe.
Kuwedzeredzwa kuchinjika uye kushomeka kuramba: Nekuwedzera RDP, kuchinjika kwechinyorwa kunovandudzwa zvakanyanya, izvo zvinobatsira kudzivirira kuitika kwekutsemuka.
Inowanzo shandiswa mumasisitimu ekudzivirira, flexible putty, kugadzirisa zvinhu, nezvimwe.
Kuvandudza kusamira kwemvura uye kusamira kwemvura:
RDP inovandudza kudzivirira kwemvura kwechinhu, ichiibvumira kuchengetedza kushanda kwakagadzikana munzvimbo ine hunyoro.
Inoshandiswa mumachira asingapindi mvura, machira ekunze emadziro, nezvimwe.
Kuvandudzwa kwekuita kwekuvaka:
RDP inogona kuvandudza mashandiro ekuvaka ehupfu hwakaoma zvinhu, zvichiita kuti kuvaka kuve nyore uye kushanda nesimba.
Inoshandiswa zvakanyanya mu-self-leveling pasi zvinhu, machira, nezvimwe.
Yakavandudzwa kusimba uye kuramba kwemamiriro ekunze: Nekuda kwekuwedzera kweRDP, kusimba uye kuramba kwemamiriro ekunze kwechinhu chacho kunovandudzwa zvakanyanya, uye inokwanisa kumira muyedzo wenzvimbo dzakaomarara.
Inoshandiswa kune ekunze madziro masisitimu, padenga coatings, nezvimwe.
Mafungiro ekusarudza RDP yakakodzera
Mamiriro ekushandisa:
Sarudza iyo yakakodzera RDP mhando zvinoenderana nechaiyo mamiriro ekushandisa, semuenzaniso, maapplication ekunze anoda RDP ine yakanaka yemamiriro ekunze kuramba.
Kudzora mutengo:
Pachimiro chekusimbisa kuita, zvinodikanwa kuti utarise mutengo wezvinhu uye sarudza iyo inodhura RDP.
Kuenderana:
RDP inofanirwa kunyatsoenderana nezvimwe zvinhu kuti ive nechokwadi chekugadzikana uye kuita kuenderana kwemusanganiswa.
Performance zvinodiwa:
Sarudza iyo yakakodzera RDP mhando zvinoenderana neinodiwa zvivakwa (sekuchinjika, kunamatira, kuramba mvura, nezvimwewo).
Redispersible latex poda inoita basa rakakosha muzvivakwa zvemazuva ano zvekuvaka, uye mhando dzayo dzakasiyana dzinopa mhinduro dzinochinjika kune dzakasiyana siyana dzekuvaka. Kusarudza iyo yakakodzera RDP mhando inogona kuvandudza zvakanyanya mashandiro ezvivakwa zvekuvaka, nekudaro kuvandudza kunaka uye kusimba kwemapurojekiti ekuvaka.
