VAE poda RDP (Redispersible) polymer poda inowanzo shandiswa zvinowedzera muindasitiri yekuvaka. Inowedzerwa kune zvigadzirwa zvesimende zvakadai sematairi ekunamatira, self-leveling compounds uye kunze kwemadziro ekudzivirira masisitimu ekuvandudza zvinhu zvakadai sekushanda, kunamatira uye kushanduka. Saizi yechikamu, kuwanda kwehuwandu uye viscosity yeRD polymer powders akakosha paramita anokanganisa mashandiro avo mumashandisirwo aya. Ichi chinyorwa chinotarisa pane viscosity bvunzo nzira yeVAE hupfu RD polymer hupfu.
Viscosity inotsanangurwa sechiyero chekuramba kwemvura kuyerera. Kune VAE hupfu RD polymer hupfu, viscosity yakakosha parameter inokanganisa kuyerera uye kushanda kwesamende misanganiswa. Iyo yakakwirira viscosity, zvakanyanya kuoma kuti hupfu husanganise nemvura, zvichiita kuti mapundu uye kupararira kusina kukwana. Naizvozvo, zvakakosha kwazvo kuchengetedza viscosity level yeRD polymer poda kuti uwane hunoenderana mhando yechigadzirwa chekupedzisira.
Iyo viscosity yekuyedza nzira yeVAE poda RD polymer hupfu inoitwa uchishandisa inotenderera viscometer. A rotational viscometer inoyera torque inodiwa kutenderedza spindle mukati memuenzaniso wepolymer poda yakaturikwa mumvura. Iyo spindle inotenderera pane imwe sipidhi uye torque inoyerwa ne centipoise (cP). Iyo viscosity yepolymer poda inozoverengerwa zvichibva pane torque inodiwa kutenderedza spindle.
Matanho anotevera anotsanangura maitiro eViscosity Test Method yeVAE Powder RD Polymer Powder.
1. Kugadzirira kwemuenzaniso: Tora mumiririri wemuenzaniso weRD polymer powder uye uremeke kune iri pedyo 0.1 g. Chinja sample mugaba rakachena, rakaoma uye rine tara. Nyora huremu hwegaba uye sampuli.
2. Kuparadzira polima upfu: Paridza polima poda mumvura maererano nemirairo yemugadziri. Kazhinji, hupfu hwepolymer hunosanganiswa nemvura uchishandisa high speed mixer. Sanganisa hupfu hwepolymer nemvura kweanenge maminetsi mashanu kana kusvika musanganiswa wakafanana wawanikwa. Iko kusanganisa kumhanya uye nguva inofanirwa kuenderana mukati meyedzo.
3. Viscosity kuyerwa: shandisa viscometer inotenderera kuyera viscosity yepolymer poda kuturika. Iyo spindle size uye kumhanya kunofanirwa kusarudzwa zvinoenderana neinotarirwa viscosity yepolymer poda. Semuenzaniso, kana yakaderera viscosity inotarisirwa, shandisa diki diki saizi uye yakakwirira RPM. Kana yakakwirira viscosity inotarisirwa, shandisa saizi yakakura yekuruka uye yakaderera kumhanya.
4. Calibration: Usati watora zviyero, gadzirisa viscometer maererano nemirairo yemugadziri. Izvi zvinosanganisira kuseta zero point uye calibrating neyakajairwa mhinduro yeinozivikanwa viscosity.
5. Edza torque: Isa rotor mupolymer powder kuturika kusvikira yanyura zvachose. Mushonga haufanire kubata pasi pegaba. Tanga kutenderedza spindle uye kumirira kuti torque kuverenga kudzikame. Rekodha kuverenga kwe torque mu centipoise (cP).
6. Replicate: Zviyero zvinokwana zvitatu zvakatorwa kune imwe neimwe sampuli uye avhareji viscosity yakaverengwa.
7. Kuchenesa: Mushure mokunge kuyerwa kwapera, chenesa rotor uye mudziyo zvakakwana nemvura uye detergent. Shamba nemvura yakasvibiswa uye woomesa zvakanaka.
Iyo viscosity yeRD polymer poda inobatwa nezvinhu zvakati wandei zvinosanganisira tembiricha, pH uye kutarisisa. Nokudaro, zvakakosha zvikuru kuyera viscosity pasi pemamiriro akaenzana. Zvakare, zviyero zvenguva dzose viscosity zvinofanirwa kutorwa kuti ive nechokwadi chekuenderana kweRD polymer poda.
Muchidimbu, iyo viscosity yekuyedza nzira yeVAE powder RD polymer hupfu muyedzo wakakosha wekuona fluidity uye kushanda kwesemende-based zvigadzirwa. Kuyedzwa kunofanirwa kuitwa uchishandisa yakajairwa michina uye maitiro ekuwana iwo chaiwo uye anoburitsa mhedzisiro. Viscosity zviyero zvinofanirwa kutorwa nguva nenguva kuti ive nechokwadi chemhando yeRD polymer poda.
