Kusiyana pakati pePlasticizer uye Superplasticizer

Plasticizers uye superplasticizers ese ari maviri marudzi emakemikari ekuwedzera anoshandiswa mukongiri musanganiswa kuvandudza kushanda, kuderedza mvura zvirimo, uye kuwedzera zvimwe zvimiro zvekongiri. Nekudaro, ivo vanosiyana mumaitiro avo ekuita uye chaiwo mabhenefiti avanopa. Heino misiyano yakakosha pakati peplasticizers uye superplasticizers:

1. Mechanism of Action:
   • Plasticizers: Plasticizers imvura-inonyungudika organic komisheni inopindirana nepamusoro pemasimende, inoderedza kupindirana kwemasimba ekukwezva uye kunatsiridza kupararira kwezvikamu zvesimende mumusanganiswa. Ivo vanoshanda zvakanyanya nekuzora zvimedu, izvo zvinobvumira kuwedzera fluidity uye nyore kubata kwekongiri musanganiswa.
   • Superplasticizers: Superplasticizers, inozivikanwawo seyakakwira-range mvura inoderedza (HRWR), inoshanda zvakanyanya-inoderedza mvura maajenti anoparadzira masimende simende zvakanyanya kupfuura mapurasitiki. Vanoshanda nekushambadza pamusoro pezvikamu zvesimende uye kugadzira firimu rakatetepa, rinogadzira simba rakasimba rinosemesa pakati pezvikamu, nokudaro kuderedza mvura-ku-simende reshiyo pasina kukanganisa kushanda.
2. Kuderedza Mvura:
   • Plasticizers: Plasticizers anowanzo dzikisa mvura yemukati musanganiswa wekongiri ne5% kusvika 15% uchichengetedza kushanda.
   • Superplasticizers: Superplasticizers inogona kuwana yakakwira mazinga ekudzikisa mvura, kazhinji muhuwandu hwe20% kusvika 40%, ichibvumira kuvandudzwa kwakakosha musimba rekongiri, kusimba, uye kuita.
3. Dosage:
   • Plasticizers: Plasticizers anowanzo shandiswa pakaderera dosages zvichienzaniswa ne superplasticizers nekuda kwekugona kwavo kudzikisira mvura.
   • Superplasticizers: Superplasticizers inoda madosi epamusoro kuti uwane iyo inodiwa kudzikiswa kwemvura uye inowanzoshandiswa pamwe chete nezvimwe zvinosanganiswa kuti uwedzere kuita.
4. Mhedzisiro paKushanda:
   • Plasticizers: Plasticizers anonyanya kuvandudza kushanda uye kuyerera kwekongiri musanganiswa, zvichiita kuti zvive nyore kuisa, compact, uye kupedza.
   • Superplasticizers: Superplasticizers inopa mabhenefiti akafanana kune epurasitiki asi anogona kuwana mazinga epamusoro ekushanda uye kuyerera, achibvumira kugadzirwa kwemvura zhinji uye yekuzvibatanidza kongiri musanganiswa.
5. Applications:
   • Plasticizers: Plasticizers anowanzoshandiswa mumhando dzakasiyana-siyana dzekongiri zvikumbiro apo kuvandudza kushanda uye nyore kubata kunodiwa, senge yakagadzirira-musanganiswa kongiri, precast kongiri, uye shotcrete.
   • Superplasticizers: Superplasticizers anowanzo shandiswa mune yakakwira-inoshanda kongiri musanganiswa uko kusimba kwepamusoro, kusimba, uye kuyerera hunhu hunodiwa, senge muzvivakwa zvepamusoro-soro, mabhiriji, uye mapurojekiti ezvivakwa.

Muchidimbu, nepo maplasticizers uye superplasticizers achishandiswa kuvandudza kushanda uye kuita kwekongiri musanganiswa, superplasticizers inopa hukuru hwekudzikisa mvura uye inonyanya kushandiswa mukuita kwepamusoro kongiri kunyorera uko kwakasarudzika simba, kusimba, uye kuyerera kwakakosha.
