Ib tug ntawm peb cov neeg muas zaub nug kuv: 'Yuav ua li cas yog koj ntau lawm mus? Nws tseem zoo?

uas ua rau kuv paub tias Tuam Tshoj Ib puag ncig kev tiv thaiv twb muaj kev cuam tshuam loj heev rau cov khoom siv tshuaj lom neeg xws li cov khoom sib xyaw ua ke hauv Suav teb.

Cia kuv qhia rau koj txij thaum pib.

Raws li peb txhua tus paub, Tuam Tshoj txhim kho sai heev rau xyoo no, lub sijhawm no, qhov teeb meem ntawm ib puag ncig tau ntau dua thiab hnyav dua.rau cov khoom sib xyaw ua ke, xws li sodium naphthalene formaldehyde, polycarboxylate superplasticizer, thiab lwm yam thiab lawv cov khoom siv raw khoom ua rau dej thiab huab cua ntau ntau.

Raws li thib ob tiam pob zeb admixture, sodium naphthalene formaldehyde, rau nws cov khoom siv raw, muaj cov qib qib naphthalene thiab formaldehyde.besides, thaum lub sij hawm ntau lawm, muaj ntau ntau pungent tsw thiab hmoov av particle.

Raws li qhov tseeb tiam tshiab cov khoom sib xyaw, polycarboxylate superplasticizer, yeej ib txwm muaj ntxhiab tsw txawv txav nyob ib puag ncig polycarboxylate superplasticizer cog.

Tuam Tshoj tsoomfwv pib paub tias qhov no tsis yog txoj hauv kev tsim nyog rau kev txhim kho kev lag luam.lawv pib teeb tsa ib puag ncig saib xyuas pab pawg los daws cov teeb meem muaj kuab paug.

Raws li ib qho ntawm cov kev lag luam hnyav hnyav, ntau cov khoom sib xyaw ua ke cuam tshuam txog kev tsim khoom lag luam tsis muaj daim ntawv tso cai ua lag luam lossis tsis muaj txoj hauv kev kom muaj kev tswj hwm cov pa phem raug yuam kom kaw.
