Tawv Additive Test

(1) Cov khoom siv: tanning agents, retanning agents, fatliquoring agents, degreasing agents, liming agents, de ashing agents, enzyme npaj, softeners, fillers, thickeners, leveling agents, fixing agents, waterproofing agents, anti fouling agents, hand feel agents, finishing agents, brighteners, inhibitors, inhibitors dispersants thiab lwm cov txheej txheem tawv ntau lawm additives.

(2) Cov xwm txheej siv tau: kev lees txais cov khoom siv raw, kev tswj cov txheej txheem tsim khoom, kev soj ntsuam cov khoom tiav, kev ntsuam xyuas kev nyab xeeb ib puag ncig, kev sim ua raws li kev txiav txim, kev txiav txim siab.

(1) Cov tsos mob thiab lub cev thiab tshuaj lom neeg
Qhov tshwm sim, xim, tsw, cov ntsiab lus tsis zoo, tsis yog - cov teeb meem tsis hloov pauv, pH tus nqi, qhov ceev, viscosity, fineness, particle loj, noo noo, tshauv ntsiab lus, solubility, dispersibility, emulsion stability, cia stability, khov -thaw stability.

(2) Kev siv cov txheej txheem kev ua haujlwm
Defatting efficiency, tshauv tshem tawm cov nyhuv, enzyme kev ua, tanning coefficient, retanning thiab filling zog, softness, fullness, evenness, transparency, kho nyhuv, waterproofing, roj kuj, stain kuj, tactile nyhuv, glossiness, nplaum lub zog, zaj duab xis - tsim cov khoom, thiab tsis kam mus qhuav thiab ntub so.

(3) Kev ua tau zoo cuam tshuam nrog cov khoom tawv
Tear lub zog, tensile zog, elongation, hnav tsis kam, flexural tsis kam, yellowing kuj, aging kuj, hws kuj, ntxuav tsis kam, xim ceev, breathability, thiab dej vapor permeability.

(4) Ib puag ncig thiab kev nyab xeeb ntsuas
Dawb formaldehyde, banned azo dyes, hnyav hlau ( lead, cadmium, mercury, chromium, arsenic, npib tsib xee, cobalt), hexavalent chromium, polycyclic aromatic hydrocarbons, phthalates, alkylphenol polyoxyethylene ether (APEO), VOCs, penmethylene chloride, fumarate, residual pwm inhibitors, antibacterial thiab bactericidal zog, corrosiveness, mob toxicity.
