Kev tsim kho tshuaj muaj txiaj ntsig zoo txhim kho kev ua haujlwm ntawm cov khoom siv hauv tsev thiab txhim kho kev tsim kho los ntawm cov txheej txheem xws li lub cev txhaws, tshuaj lom neeg, lossis kev txhawb nqa kev sib tshuam. Nyob deb ntawm kev ua ib qho kev pab cuam nkaus xwb, lawv yog cov khoom tseem ceeb uas ua lub luag haujlwm sib sib zog nqus thiab tseem ceeb hauv kev tsim cov khoom siv thiab kev ua kom zoo ntawm lawv cov khoom.

 

1. Concrete Admixtures: Lub hauv paus ntawm Kev Tswj Xyuas Kev Ua Haujlwm

Cov khoom sib xyaw ua ke yog cov tshuaj siv siv ntau tshaj plaws; Lawv cov txheej txheem ntawm kev txiav txim sib txawv nyob ntawm lawv cov haujlwm tshwj xeeb:

Dej Reducers: Los ntawm adsorbing rau saum npoo ntawm cov cement, lawv tsim electrostatic repulsion uas disperses cov khoom ntau uniformly. Qhov no txo ​​cov ntsiab lus dej uas yuav tsum tau ua, yog li txhim kho cov pob zeb ua kom muaj zog thiab kav ntev.
Retarders / Accelerators: Cov neeg ua haujlwm no tswj tus nqi ntawm cov cement hydration cov tshuaj tiv thaiv. Retarders ncua sij hawm teem sijhawm- ua rau lawv tsim nyog rau kev tsim kho nyob rau hauv siab - qhov kub thiab txias - thaum lub sij hawm accelerators ceev cov txheej txheem hardening, yog li shortening lub curing voj voog.
Waterproofing Agents & Corrosion Inhibitors: Waterproofing agents ua hauj lwm los ntawm thaiv capillary pores los tiv thaiv ya raws, hos corrosion inhibitors tsim ib tug tiv thaiv zaj duab xis nyob rau saum npoo ntawm steel reinforcement los tiv thaiv chloride ions los ntawm triggering corrosion.

 

2. Polyurethane Foaming Catalysts (xws li LED-103): Tswj cov txheej txheem Foaming

Nyob rau hauv cov ntaub ntawv siv rau thermal rwb thaiv tsev, sealing, thiab cov ntawv zoo sib xws, polyurethane foaming catalysts pab txhawb cov tshuaj tiv thaiv ntawm isocyanates thiab polyols. Los ntawm kev tswj tus nqi thiab kev ruaj ntseg ntawm cov npuas tsim, lawv ncaj qha cuam tshuam rau lub npuas qhov ntom, hardness, thiab thermal rwb thaiv tsev zog. Tsis tas li ntawd, cov catalysts no muaj peev xwm hloov mus rau qhov sib txawv ntawm qhov kub thiab txias, yog li ua kom muaj kev ruaj ntseg ntau lawm.

 

3. Adhesives & Sealants: Ua kom ruaj ntseg Bonding

Kev tsim cov nplaum hmoov lossis kua nplaum ua haujlwm los ntawm kev tsim cov tshuaj colloidal thaum tawg ntawm lawv cov khoom siv polymeric. Qhov kev daws teeb meem no tsim peb - qhov sib txuas network qauv ntawm cov cement-raws li substrates, yog li txhim kho kev sib raug zoo ntawm kev sib raug zoo thiab kev sib tsoo. Piv txwv li, cov nplaum nplaum uas muaj polypropylene fibers tuaj yeem txhim kho qhov yooj yim thiab ua haujlwm ntawm cov tshuaj khib nyiab, tiv thaiv cov teeb meem xws li hollowing lossis detachment.
