Kev npaj cov txheej txheem ntawm cov ntaub ntawv sealant

Cov txheej txheem kev npaj ntawm cov ntaub ntawv sealant ncaj qha txiav txim siab lawv qhov kawg kev ua tau zoo thiab kev siv tau zoo. Cov txheej txheem feem ntau suav nrog kev xaiv cov khoom siv raw, kev tsim qauv, sib xyaw thiab dispersion, deaeration, nrog rau kev tsim thiab ntim. Txawm hais tias cov txheej txheem tshwj xeeb sib txawv ntawm ntau hom sealants, tag nrho cov txheej txheem kev npaj tseem zoo sib xws.

Nyob rau hauv cov txheej txheem xaiv raw khoom, tsim nyog cov resins, muab tub lim, plasticizers, thiab functional additives raug xaiv raws li kev ua tau zoo. Lub hauv paus cob yog cov khoom tseem ceeb uas txiav txim siab tag nrho cov khoom, thiab cov tshuab xws li silicone, polyurethane, lossis acrylic raug xaiv nyob ntawm daim ntawv thov. Fillers thiab additives yog siv los kho cov khoom siv kho tshuab thiab kev ua haujlwm.

Thaum lub sij hawm tsim formulation, txhua feem yog scientific proportioned kom ua tau ib tug balanced kev ua tau zoo profile. Lub formulation yuav tsum xav txog adhesion, elasticity, durability, daim ntawv thov kev ua tau zoo, thiab tus nqi efficiency. Ib qhov zoo- tsim qauv tsim yog qhov tseem ceeb los ua kom cov khoom ruaj khov.

Nyob rau hauv qhov sib tov thiab dispersion theem, tag nrho cov ntaub ntawv raw yog sib xyaw kom huv si siv cov cuab yeej tshwj xeeb los tsim ib qho kev sib txuam thiab ruaj khov. Rau siab -viscosity lossis ntau- cov khoom siv, cov khoom siv nqus tsev sib xyaw feem ntau yog siv los txhim kho kev ua kom tawg thiab tiv thaiv agglomeration.

Deaeration yog ib kauj ruam tseem ceeb hauv kev tsim khoom. Cov npuas cua tuaj yeem raug qhia thaum sib xyaw, thiab yog tias tsis raug tshem tawm, lawv tuaj yeem cuam tshuam qhov ntom ntom thiab sealing kev ua tau zoo ntawm cov khoom. Nqus deaeration los yog static so txoj kev yog feem ntau siv los xyuas kom meej ib tug uniform thiab compact sab hauv.

Thaum lub sij hawm tsim thiab ntim, cov ntaub ntawv raug ua tiav rau hauv paste, gel, los yog ob -cov ntaub ntawv ntim cov khoom nyob ntawm seb hom khoom, thiab tom qab ntawd muab kaw cia kom ruaj khov thaum thauj thiab siv.

Zuag qhia tag nrho, kev npaj cov ntaub ntawv sealant yog ntau- cov txheej txheem sib koom ua ke nrog kev koom ua ke ntawm cov ntaub ntawv tshawb fawb thiab txheej txheem engineering. Tsuas yog los ntawm kev tswj hwm nruj ntawm txhua theem tuaj yeem tsim cov sealants nrog kev ua haujlwm ruaj khov thiab txhim khu kev qha zoo.
