Sodium naphthalene sulfonate formaldehyde (SNF)

Sodium naphthalene sulfonate formaldehyde (SNF) yog ib qho tshuaj siv dav hauv kev lag luam tawv. Nws belongs rau cov chav kawm ntawm cov hluavtaws dispersing agents thiab feem ntau ua hauj lwm raws li ib tug dispersant thiab wetting tus neeg sawv cev nyob rau hauv tawv ua. Cov khoom sib xyaw no ua lub luag haujlwm tseem ceeb hauv ntau theem ntawm cov tawv nqaij, pab hauv kev npaj, dyeing, thiab ua tiav cov khoom tawv. Hauv tsab xov xwm no, peb yuav tshawb xyuas cov khoom, kev siv, thiab cov txiaj ntsig ntawm sodium naphthalene sulfonate formaldehyde hauv kev lag luam tshuaj tawv nqaij.

Khoom:
Sodium naphthalene sulfonate formaldehyde yog cov dej-soluble compound tau los ntawm naphthalene, hydrocarbon. Nws muaj cov khoom zoo heev dispersing thiab ntub dej, ua rau nws tsim nyog rau kev ua tawv. Cov compound feem ntau muaj nyob rau hauv daim ntawv ntawm cov hmoov brownish los yog kua, nrog ib tug yam ntxwv sulfonate tsw. SNF muaj qib siab ntawm solubility hauv dej, tso cai rau kev sib koom ua ke hauv ntau hom tawv nqaij.

Daim ntawv thov:
1. Pre-Tanning: Sodium naphthalene sulfonate formaldehyde feem ntau yog siv los ua tus neeg sawv cev dispersing thaum lub sij hawm ua ntej tanning. Nws pab tshem tawm cov impurities, xws li av, roj, thiab cov protein seem, los ntawm cov nqaij nyoos los yog tawv nqaij. SNF pab tshem tawm cov impurities, tso cai rau lawv yooj yim tshem tawm thaum lub sij hawm ntxuav tom ntej.

2. Dyeing: SNF ua raws li tus neeg sawv cev dispersing thiab wetting thaum lub sij hawm dyeing. Nws txhim kho cov dispersion ntawm dyes nyob rau hauv cov tawv nqaij, ua rau uniform thiab vibrant xim. Tsis tas li ntawd, nws txhim khu kev nkag mus ntawm dyes rau hauv cov tawv fibers, ua kom cov xim zoo nkauj nrawm thiab ua haujlwm ntev.

3. Kev ua tiav: Nyob rau theem kawg, sodium naphthalene sulfonate formaldehyde pab hauv kev siv cov khoom tiav, coatings, thiab pigments rau cov tawv nqaij. Nws pab kom tawg cov tshuaj no sib npaug, kom ntseeg tau tias du thiab txawm tias npog. SNF kuj tseem txhim kho qhov adhesion ntawm cov tawv nqaij, txhim kho lawv cov kev tiv thaiv kev puas tsuaj, dej, thiab tshuaj lom neeg.

Cov txiaj ntsig:
1. Kev Txhim Kho Kev Ua Haujlwm Zoo: SNF txhawb nqa kev ua haujlwm zoo ntawm cov tawv nqaij los ntawm kev pab cuam hauv kev tawg ntawm ntau yam khoom. Nws pab tshem tawm cov impurities, pab nyob rau hauv daim ntawv thov ntawm dyes thiab tiav, thiab txhim kho tag nrho cov zoo ntawm cov khoom tawv.

2. Kev Txhim Kho Xim Txhim Kho: Cov khoom tawg ntawm sodium naphthalene sulfonate formaldehyde pab txhawb rau kev faib tawm thiab nkag mus ntawm cov xim rau hauv cov tawv fibers. Qhov no ua rau cov xim vibrant thiab kav ntev, muab qhov zoo nkauj zoo nkauj rau cov khoom tawv tiav.

3. Kev Pab Cuam Tshaj Plaws: SNF ua kom muaj kev sib koom ua ke ntawm kev ua tiav, txheej txheej, thiab cov xim ntawm cov tawv nqaij. Qhov no ua rau kev txhim kho adhesion, muaj zog tiv thaiv kev hnav thiab tsim kua muag, thiab kev tiv thaiv zoo dua tiv thaiv ib puag ncig.

4. Kev txiav txim siab ib puag ncig: Sodium naphthalene sulfonate formaldehyde yog suav tias yog kev nyab xeeb rau kev siv hauv kev lag luam tawv. Nws yog biodegradable, tsis muaj tshuaj lom, thiab tsis ua rau muaj kev puas tsuaj ib puag ncig thaum siv raws li cov lus pom zoo.

Hauv kev xaus, sodium naphthalene sulfonate formaldehyde yog ntau yam thiab muaj txiaj ntsig tshuaj lom neeg hauv kev lag luam tawv nqaij. Nws tshwj xeeb dispersing thiab wetting zog ua rau nws ib tug indispensable tivthaiv nyob rau hauv ntau theem ntawm tawv ua. Los ntawm kev ua ntej tanning mus rau dyeing thiab xov, SNF pab txhawb kev txhim kho kev ua tau zoo, txhim kho xim, thiab nce saum npoo ntawm cov khoom tawv. Tsis tas li ntawd, nws ib puag ncig kev sib raug zoo ntxiv rau nws qhov kev thov tag nrho raws li cov khoom tseem ceeb hauv kev lag luam tawv.
