Redispersible polymer poda (RDP) ipfu chena inonyungudika nyore mumvura.Yakagadzirwa nepolymer emulsion spray-yakaomeswa neakakosha maitiro.RDP inoshandiswa zvakanyanya mundima yekuvaka nekuda kwekuita kwayo kwakanaka, iyo inogona kuvandudza mashandiro ecementitious zvinhu.Mune ino post, isu tichakurukura kugona kweRDP yekuvandudza Mortar.
Mabasa eRDP
1. Kuvandudza zvinhu zvemagetsi
RDP inogona kukwidziridza zvimisikidzwa zvesimende zvinhu, zvinosanganisira kumanikidza simba, flexural simba uye tensile simba.Izvi zvinodaro nekuti kana RDP yakasanganiswa nesimende, inogona kuumba dense uye dense chimiro, chinogona kuvandudza kunamatira pakati pezvimedu uye kuderedza porosity yechinhu.Naizvozvo, inogona kunyatso kuvandudza ma mechanical properties yezvinhu.
2. Wedzera kubatana
Kubatana pakati pevhu particles kunoenderana zvakanyanya neayo viscosity.Iyo yakakwirira viscosity, iyo inowedzera kubatana pakati pezvimedu.Izvi zvinonyanya kukosha nedhaka remasonry sezvo richiita kuti dhaka rirege kudonha kana kuyerera panguva yekuvaka.RDP inogona kuwedzera zvakanyanya viscosity yedhaka, nekudaro ichiwedzera iyo yakabatana simba pakati pezvimedu uye kuve nechokwadi chemhando yeprojekiti yemasonry.
3. Kuvandudza kuchengetedza kwemvura
Kuchengetedza mvura chinhu chakakosha chedhaka.Inotsanangurwa sekukwanisa kwechinhu kuchengetedza mvura mukati me matrix ayo.Kana kuchengetwa kwemvura kusina kukwana, dhaka rinooma nokukurumidza, izvo zvichakanganisa kushanda kwayo uye kuderedza simba rayo.RDP inogona kuvandudza zvakanyanya kuchengetwa kwemvura kwedhaka, kudzivirira kuti isaoma nekukasira, uye kuve nechokwadi chekushanda kwakanaka.
4. Kuwedzera kushanda
Kushanda (workability) zvinoreva kugona kwedhaka kugadzirwa nekuumbwa zviri nyore.Iko kushanda kwedhaka kwakabatana zvakanyanya nekuenderana kwayo, viscosity uye kuchengetedza kwemvura kuita.RDP inogona kuvandudza zvakanyanya kushanda kwedhaka nekuwedzera kuwirirana kwayo uye viscosity.Inogonawo kupa zvinhu zvakanaka zvekuchengetedza mvura, izvo zvinogona kuve nechokwadi chekushanda kwedhaka kwenguva yakareba.
5. Deredza kutsemuka
Kutsemuka idambudziko rinowanzoitika nesement-based materials.Inokonzerwa nezvikonzero zvakawanda, zvakadai se shrinkage rate yezvinhu, nzira yekushandiswa, mamiriro ezvakatipoteredza, nezvimwewo RDP inogona kuderedza dambudziko rekuputika nekuwedzera kushanduka kwezvinhu uye ductility.Inogonawo kupa kunamatira kwakanaka pakati pezvimedu, izvo zvinogona kuderedza kuunganidza kwekunetseka mune zvinyorwa uye kudzivirira kuputika.
6. Kuvandudza kusimba
Durability zvinoreva kugona kwechinhu kuramba kuparara kunokonzerwa nemakemikari, muviri uye zvakatipoteredza.RDP inogona kuvandudza kusimba kwedhaka nekusimudzira kuramba kwayo kumvura, shanduko yekushisa uye mamiriro ekunze.Inogonawo kupa kunamatira kwakanaka pakati pezvimedu uye kuwedzera iyo firimu-inogadzira zvimiro zvedhaka, izvo zvinogona kuvandudza kugona kwayo kuramba kukukurwa uye kupfeka.
mukupedzisa
Kupfupisa, mhedzisiro yeRDP pakuvandudza dhaka yakakosha.Inogona kuwedzera zvivakwa zvemuchina, kuwedzera kubatana, kuvandudza kuchengetwa kwemvura, kuwedzera kushanda, kuderedza kuputika, nekuvandudza kusimba.Izvi zvivakwa zvakakosha kuve nechokwadi chemhando yebasa remasonry uye kushanda kwenguva refu kwezvivakwa.Naizvozvo, RDP yakashandiswa zvakanyanya mumunda wekuvaka uye yave yakakosha yekuwedzera yekuvandudza mashandiro edhaka.
