naphthalene sulfonic acid-formaldehyde condensate sodium ntsev

Naphthalenesulfonic acid-formaldehyde condensate sodium ntsev, tseem hu ua sodium naphthalene sulfonate formaldehyde condensate (SNF) yog ntau yam thiab siv tau dej-txo cov tshuaj siv nyob rau hauv ntau qhov kev siv hauv kev tsim kho.

SNF feem ntau yog siv los tsim cov pob zeb ua haujlwm siab. Nws yog siv dav siv superplasticizer uas pab txo cov dej uas xav tau kom ua tiav qhov kev xav tau ntawm kev sib xyaw ua ke. Kev siv SNF hauv kev tsim cov pob zeb ua rau lub sijhawm teem sijhawm sai dua thiab txhim kho lub zog, uas tso cai rau lub sijhawm hloov pauv sai ntawm cov haujlwm tsim kho.

SNF kuj tseem siv los ua cov khoom tawg hauv kev tsim cov gypsum thiab cement-based qhuav-mixes. Nws pab txhim kho flowability thiab sib xws los ntawm kev tiv thaiv caking thiab clumping thaum lub sij hawm cia.

Ntxiv nrog rau kev siv hauv kev tsim kho, SNF kuj tseem siv rau hauv kev lag luam textile ua ib qho dispersant rau dyes thiab pigments. Nws pab tiv thaiv clumping thiab tsis sib npaug ntawm cov dyes, ua rau muaj kev vibrant thiab sib xws ntawm cov ntaub.

Tsis tas li ntawd, SNF yog siv rau hauv kev tsim cov tawv nqaij ua ib qho dispersant thiab plasticizer. Nws pab txhim kho lub zog thiab durability ntawm tawv, thaum tseem txhim kho nws cov dej tsis kam.

Zuag qhia tag nrho, SNF yog cov tshuaj muaj ntau yam thiab siv tau zoo uas muaj ntau yam kev siv hauv ntau yam lag luam. Nws siv hauv kev tsim kho, textile, thiab tawv kev lag luam tau txais kev pabcuam zoo hauv kev ua tiav kev ua haujlwm zoo thiab zoo hauv cov txheej txheem ntau lawm.
