Upfu hweVAE Upfu hweRDP (Redispersible) polymer hupfu hunoshandiswa zvakanyanya muindasitiri yekuvaka. Hunowedzerwa kune zvigadzirwa zvakagadzirwa nesimende zvakaita sematiles, macompounds anozvienzanisa uye masisitimu ekudzivirira madziro ekunze kuti zvivandudze hunhu hwakadai sekushanda, kunamira uye kuchinjika. Saizi yezvikamu, huwandu hwakawanda uye kusimba kweRD polymer powders zvinhu zvakakosha zvinokanganisa mashandiro azvo mukushandiswa uku. Chinyorwa chino chichatarisa pane nzira yekuedza kusimba kweVAE powder RD polymer powder.
Kusimba kunotsanangurwa sechiyero chekusagona kwemvura kuyerera. Kune VAE powders RD polymer powders, kusimba chinhu chakakosha chinokanganisa kusimba uye kushanda kwemusanganiswa wesimende. Kusimba kwacho kwakanyanya, ndiko kuoma kwazvinoita kuti upfu husanganiswe nemvura, zvichikonzera mapundu uye kupararira kusina kukwana. Saka, zvakakosha kuchengetedza mwero wekusimba kweRD polymer powder kuti uwane mhando yakafanana yechigadzirwa chekupedzisira.
Nzira yekuedza viscosity yeVAE powder RD polymer powder inoitwa uchishandisa rotational viscometer. Rotational viscometer inoyera torque inodiwa kuti itenderedze spindle mukati memuenzaniso wepolymer powder yakasungirirwa mumvura. Spindle inotenderera nekumhanya kwakatarwa uye torque inoyerwa mu centipoise (cP). Viscosity yepolymer powder inozoverengerwa zvichibva pa torque inodiwa kuti itenderedze spindle.
Matanho anotevera anotsanangura maitiro ekushandisa nzira yekuedza Viscosity yeVAE Powder RD Polymer Powder.
1. Kugadzirira muenzaniso: Tora muenzaniso unomiririra weRD polymer powder woyera kusvika pa 0.1 g iri pedyo. Tumira muenzaniso wacho kumudziyo wakachena, wakaoma uye wakarukwa. Nyora huremu hwemudziyo nemuenzaniso.
2. Paradzira upfu hwepolymer: Paradzira upfu hwepolymer mumvura zvichienderana nemirairo yemugadziri. Kazhinji, upfu hwepolymer hunosanganiswa nemvura uchishandisa muchina wekusanganisa unomhanya zvakanyanya. Sanganisa upfu hwepolymer nemvura kwemaminitsi mashanu kana kusvika wawana musanganiswa wakafanana. Kumhanya uye nguva yekusanganisa zvinofanirwa kunge zvakafanana mukati mebvunzo yese.
3. Kuyera kusimba kwesimbi: shandisai rotational viscometer kuti muyere kusimba kwepolymer powder suspension. Saizi yespindle nekumhanya kwayo zvinofanira kusarudzwa zvichienderana nekusimba kunotarisirwa kwepolymer powder. Semuenzaniso, kana kusimba kushoma kunotarisirwa, shandisai saizi diki yespindle uye RPM yakakwira. Kana kusimba kunotarisirwa, shandisai saizi yakakura yespindle uye kumhanya kwakaderera.
4. Kuenzanisa: Usati watora zviyero, enzanisa viscometer zvichienderana nemirairo yemugadziri. Izvi zvinosanganisira kuisa zero point uye kuyera nemhinduro dzakajairwa dze viscosity inozivikanwa.
5. Yera torque: Isa rotor mu polymer powder suspension kusvika yanyura zvachose. Spindle haifanirwe kubata pasi pemudziyo. Tanga kutenderedza spindle womirira kuti torque irambe yakasimba. Nyora torque mu centipoise (cP).
6. Kudzokorora: Zviyero zvitatu zvakatorwa pamuenzaniso wega wega uye avhareji ye viscosity yakaverengerwa.
7. Kuchenesa: Kana kuyerwa kwapera, chenesa rotor nechirongo zvakanaka nemvura nesipo. Shamba nemvura yakacheneswa woomesa nokungwarira.
Kuwanda kwehupfu hweRD polymer kunokanganiswa nezvinhu zvakawanda zvinosanganisira tembiricha, pH uye huwandu hwezvinhu. Saka, zvakakosha kuyera hupfu hweRD polymer pasi pemamiriro ezvinhu akajairika. Zvakare, kuyerwa kwehupfu hweRD polymer kunofanirwa kutorwa nguva dzose kuti kuve nechokwadi chekuti hupfu hweRD polymer hunoshanda nguva dzose.
Muchidimbu, nzira yekuedza viscosity yeVAE powder RD polymer powder ibvunzo yakakosha yekuona kuyerera uye kushanda kwezvigadzirwa zvakagadzirwa nesimende. Kuedza kunofanirwa kuitwa uchishandisa michina yakajairika uye maitiro kuti uwane mhedzisiro chaiyo uye inodzokororwa. Kuyerwa kwekusimba kunofanirwa kutorwa nguva nenguva kuti kuve nechokwadi chehunhu hweRD polymer powders.
