Cov yam ntxwv ntawm cov txheej txheem dej tsis zoo

Cov yam ntxwv ntawm cov txheej txheem dej tsis zoo ua lub luag haujlwm txiav txim siab hauv lawv cov dej tsis zoo, ua haujlwm ntev, thiab yoog mus rau ntau qhov chaw ua haujlwm engineering. Feem ntau, cov txheej txheem no yog tsim los ntawm cov yeeb yaj kiab- cov khoom tsim, cov tshuab muab tub lim, cov khoom siv ntxiv, thiab cov kuab tshuaj lossis cov xov xwm tawg, txhua yam ua haujlwm ua ke los tsim kom muaj kev tiv thaiv ruaj khov.

Cov yeeb yaj kiab- cov khoom tsim yog cov khoom tseem ceeb ntawm cov qauv, txiav txim siab qhov kev ua tau zoo ntawm cov txheej txheem. Cov tshuab muaj xws li polymer emulsions, polyurethane prepolymers, thiab hloov bitumen. Once cured, they form a continuous and dense waterproof layer that acts as the primary barrier against moisture penetration, with flexibility, strength, and durability directly influencing overall performance.

Lub tshuab muab tub lim yog siv los txhim kho cov khoom siv kho tshuab thiab cov qauv kev ruaj ntseg. Nws pab txhim kho kev tawg tsis kam, puas ntsoog, thiab qhov seem stability. Feem ntau cov khoom siv xws li calcium carbonate, talc, thiab ntau yam inorganic minerals nce qhov ntom ntawm txheej, ua rau cov txheej txheem dej tsis muaj zog thiab txhim khu kev qha.

Functional additives yog suav nrog txhawm rau txhim kho kev ua haujlwm zoo. Plasticizers txhim kho kev yooj yim, cov neeg ua hauj lwm dispersing kom cov khoom sib faib sib faib, thiab cov neeg ua hauj lwm defoaming txo cov cua npuas thaum lub sij hawm thov, ua rau kom siab dua - cov yeeb yaj kiab zoo. Txawm hais tias siv me me, cov tshuaj ntxiv no cuam tshuam rau qhov kawg ntawm cov txheej txheem.

Cov kuab tshuaj los yog dispersion media yog lub luag haujlwm rau kev kho cov khoom siv, muab kev txaus txaus thiab ua haujlwm tau zoo thaum tsim kho. Tom qab daim ntawv thov, lawv maj mam evaporate los yog koom nyob rau hauv kev kho cov tshuaj tiv thaiv, tawm hauv qab ib tug ruaj khov thiab uniform waterproof zaj duab xis.

Zuag qhia tag nrho, cov txheej dej tsis muaj dej tsis yog ib yam khoom tab sis ntau - cov khoom sib xyaw ua ke. Los ntawm kev sib npaug ntawm cov qauv tsim thiab cov qauv tsim, lawv ua tiav kev sib xyaw ua ke ntawm kev yooj yim thiab lub zog, ua kom muaj kev ntseeg tau zoo nyob rau hauv cov txheej txheem sib txawv ntawm cov substrate thiab ib puag ncig xav tau nyob rau lub sijhawm ua haujlwm ntev.
