Cov tub ntxhais sib txawv: molecular qauv txiav txim nws qhov
Cov roj silicone zoo tib yam (PDMS):
Tus qauv: nws cov molecular pob txha ntawm txoj hlua ncaj ntawm lwm silicon (si) thiab oxygen ({}}}} atom. Tag nrho molecule tsis yog - polar thiab hydrophobic (dej {{}}} Tsom cov tshuaj).
Cov duab qhia ua piv txwv: nws zoo li ib qho kev du heev, cov saw hlau tsis zoo.
204 dej - soluble Silicone Roj:
Tus qauv: Nws yog tus qauv Silicone roj backuminion gratered nrog sethylene oxide (POOS). Cov polyeten segments yog hydrophilic.
Duab medaphor: nws zoo li ib txoj hlua caj dab "amphiphilic" nrog rau "lipophilic hlaws dai" (polyethane) thiab "polyether) strung ua ke ntawm tib txoj saw hlau.
Kev sib piv ncaj qha ntawm kev ua tau zoo thiab kev ua tau zoo
Vim lawv cov qauv sib txawv ntau yam, ob qho sib txawv ntawm qhov sib txawv ntawm kev ua tau zoo:
Nta: Cov Roj Silicone (PDMS) 204 Dej - soluble Silicone Roj
Solubility: Insoluble hauv dej, soluble hauv feem ntau cov emvents organic (xws li Toluene thiab Heptane). Yuav tsum yog emulsified los ua ib qho emulsion rau siv, ua kom muaj kev sib tw ruaj khov. Nws yog mistible nrog dej hauv txhua qhov kev sib tw, ua cov tshuaj tov. Nws yog qhov yooj yim heev rau siv thiab lub kaw lus ruaj khov.
Cov haujlwm saum npoo: nws yog qhov tsis tshua muaj siab heev Nws kuj tseem muaj qhov qauv amphipilic muaj kev txhim kho cov chaw ua kom zoo, ua rau tus neeg sawv cev ntub dej thiab emulsifier zoo heev.
Kev sib xyaw: Nws muaj qhov tsis zoo nrog feem ntau cov kab polar (xws li cov dej hauv cov qauv thiab muaj ntau yam pleev xim rau nag lossis demulsification. Nws muaj qhov zoo heev nrog dej - raws cov khoom xyaw, thiab ntau yam surfactants, ua kom yooj yim los tsim.
Kev ua haujlwm: nws feem ntau muab hydrophobicity, lub roj, defoaming, thiab pwm tso tawm. Txhais tes xav tias feem ntau du thiab qhuav. Thaum khaws ib coricity, nws hais txog kev softness, smoothness, thiab cov tshuaj tivthaiv cov tshuaj tiv thaiv. Nws xav tias muaj moisturizing ntau dua thiab nplua. Nws tseem ua raws li tus choj, ruaj khov muaj cov roj silicone hauv cov dej.
Tsis muaj huab taw tes. Nws ua kom pom huab huab, lub ntsiab lus nws cov kev daws teeb meem aqueous pib turkid thaum cua sov kom sov rau ib qho kub. Cov cuab yeej no tuaj yeem siv rau hauv textile finishing kom ua tiav qhov ntev-} kawg mos nyhuv.
Qhov sib txawv tseem ceeb hauv cov chaw thov
Cov kev ua tau zoo sib txawv ncaj qha rau divergor daim ntawv thov cov xwm txheej rau ob hom roj silicone:
Cov ntawv thov ntawm cov roj silicone roj:
Defoaming cov neeg sawv cev: Siv raws li siab - effecticiing cov neeg sawv cev hauv kev lag luam xws li tshuaj lom neeg, kev kho kom zoo nkauj thiab dej khib nyiab.
Tso cov neeg sawv cev: Siv ua qhov tsis - stick txheej rau sab nraum qab ntawm cov ntawv lo thiab tapes.
Lubricants: Siv rau lubrication ntawm cov tshuab ua hluav taws xob thiab cov yas zog.
Kev saib xyuas tus kheej: Feem ntau ntxiv rau hauv daim ntawv ntawm cov emulsion, thiab ntau npaum li cas cov tshuaj yuav tsum tau nruj me ntsis los tiv thaiv kev tsim.
Cov ntawv thov ntawm 204 dej -} soluble Silicone Roj:
Textile Printing thiab Core muag muag ua tiav, nws imparts zoo muag muag, nws imparts zoo rau cov ntaub thaum tiv thaiv cov roj.
Kev saib xyuas tus kheej: Cov khoom siv tseem ceeb hauv high -}}}}}}}} {diav, lub cev ntxuav, thiab cov khoom siv tawv nqaij. Nws cov dej - Soluble Qhov uas tiv thaiv kev tsim kho thiab muab cov kev xav ua kom zoo dua qub thiab mob siab, du.
Ua liaj ua teb: Raws li cov tshuaj tsuag adjuvant, nws txhim kho kev sib kis thiab cov nplaum ntawm tshuaj tua kab ntawm cov nroj teb nplooj.
Roj fiber ntau: ib lub roj nplua nyeem zoo tshaj plaws thiab cov tshuaj tivthaiv cov tshuaj tivthaiv hauv hluavtaws fiber ntau txheej txheem.
Tsuas yog muab cov kua silicone tsis tu ncua yog tus kws tshaj lij hauv roj {{}}} Solule silicone kua yog ib tug tswv nyob rau hauv dej {}}}} kev siv.
Cov kua dej silicone tsis tu ncua zoo li tus kws tshaj lij, ua kom zoo tshaj plaws hauv oilool ib puag ncig uas yuav tsum muaj zog hydrophobicity thiab cov khoom thaiv.
