Iyo nzira yekuita yeRedispersible Polymer Powder (RDP) mudhaka rakaoma

Redispersible Polymer Powder (RDP)chinhu chakakosha chekuwedzera mukuumbwa kwedhaka rakaoma, rinopa huwandu hwemabhenefiti akadai sekuvandudza kunamatira, kubatana, kuchinjika, uye kushanda. Maitiro ayo ekuita anosanganisira matanho akawanda, kubva pakupararira mumvura kusvika pakubatana nezvimwe zvikamu mumusanganiswa wedhaka. Ngationgororei mune yakadzama meshini:

Kupararira mumvura:
RDP zvimedu zvakagadzirirwa kupararira nekukurumidza uye zvakafanana mumvura nekuda kwechimiro chavo chehydrophilic. Pamusoro pekuwedzera kwemvura kumusanganiswa wakaoma wedhaka, zvimedu izvi zvinoputika uye zvinopararira, zvichiita kugadzikana kwecolloidal suspension. Iyi nzira yekuparadzira inofumura nzvimbo yakakura yepolymer kune yakatenderedza nharaunda, ichigonesa kupindirana kunotevera.

Kugadzira Mafirimu:
Sezvo mvura inoramba ichibatanidzwa mumusanganiswa wedhaka, iyo yakapararira RDP particles inotanga kunyura, ichigadzira firimu rinopfuurira rakakomberedza cementitious particles nezvimwe zvikamu. Iyi firimu inoshanda sechipingamupinyi, ichidzivirira kusangana kwakananga pakati pesimentitious zvinhu uye unyoro hwekunze. Izvi zvakakosha pakudzikisa ingress yemvura, kuwedzera kusimba, uye kuderedza njodzi yeefflorescence uye mamwe maitiro ekuora.

Kuwedzeredzwa Kunamatira uye Kubatana:
Iyo firimu repolymer rakagadzirwa neRDP rinoshanda semumiriri wekubatanidza, kukurudzira kunamatira pakati pedhaka uye akasiyana substrates akadai sekongiri, masonry, kana mataira. Iyo firimu inovandudzawo kubatana mukati medhaka matrix nekuvhara mikaha pakati pezvimedu, nekudaro inowedzera simba rose uye kuvimbika kwedhaka rakaomarara.

Flexibility uye Crack Resistance:
Imwe yemabhenefiti akakosha eRDP kugona kwayo kupa kuchinjika kune dhaka matrix. Iyo firimu yepolymer inogadzika madiki substrate mafambiro uye nekuwedzera kupisa, kuderedza njodzi yekutsemuka. Pamusoro pezvo, DPP inokwidziridza kusimba kwesimba uye ductility yedhaka, ichiwedzera kuvandudza kuramba kwayo kutsemuka pasi pemitoro miviri uye ine simba.

Kuchengeta Mvura:
Kuvapo kweRDP mumusanganiswa wevhu kunobatsira kugadzirisa kuchengetwa kwemvura, kudzivirira kukurumidza kubuda kwemhepo panguva yekutanga yekurapa. Iyi yakawedzerwa nguva ye hydration inosimudzira yakakwana simende hydration uye inova nechokwadi chekusimudzira kwakaringana kwemagetsi zvivakwa, senge compressive uye flexural simba. Uyezve, kuchengetwa kwemvura kunodzorwa kunobatsira kuvandudza kushanda uye kurebesa kuvhurika nguva, kufambisa nyore kushandisa uye kupera kwedhaka.

Durability Enhancement:
Nekuvandudza kunamatira, kuchinjika, uye kuramba kupaza, DPP inosimudzira zvakanyanya kusimba kweakaoma dhaka zvikumbiro. Iyo firimu repolymer rinoita sechivharo chinodzivirira kubva mukunyorova kunopinda, kurwiswa kwemakemikari, uye zvinosvibisa zvakatipoteredza, nekudaro vachiwedzera hupenyu hwesevhisi yedhaka uye kuderedza zvinodiwa zvekuchengetedza.

Kuenderana neAdditives:
RDPinoratidza kugarisana kwakanaka neakasiyana-siyana ekuwedzera anowanzo shandiswa mukuoma kwedhaka maumbirwo, akadai semhepo inopinza, zvinomhanyisa, retarders, uye pigment. Izvi zvakasiyana-siyana zvinobvumira kugadziridzwa kwezvivakwa zvedhaka kuti zvisangane nezvinodiwa zvekuita zvekushandisa kwakasiyana uye mamiriro ekunze.

maitiro echiito chepolymer poda yakaparara mudhaka yakaoma anosanganisira kupararira mumvura, kuumbwa kwefirimu, kuwedzeredzwa kunamatira uye kubatana, kuchinjika uye kutsemuka kuramba, kuchengetedza mvura, kusimba kwesimba, uye kuenderana nezvinowedzerwa. Izvi zvakasanganiswa mhedzisiro zvinobatsira mukuvandudzika kwekuita, kushanda, uye kusimba kwemasisitimu edhaka rakaoma pane dzakasiyana siyana dzekuvaka.
