① Tsis tuaj yeem ua tiav qhov xav tau kev xav tau: Cov qauv muag muag ntawm qhov muag sib txawv nyob ntawm cov neeg siv khoom xav tau, xws li softness, smoothness, fluffiness, softness, oiliness, dryness, thiab lwm yam. Cov softeners sib txawv yog xaiv raws li cov qauv sib txawv. Hauv cov yeeb yaj kiab mos, muaj cov qauv sib txawv ntawm cov khoom siv softener, uas muaj cov qib sib txawv ntawm softness, fluffiness, smoothness, yellowing, thiab cuam tshuam rau cov dej nqus ntawm cov ntaub; Hauv cov roj silicone, cov khoom ntawm cov roj silicone hloov nrog cov noob hloov pauv kuj txawv, xws li cov roj amino silicone, hydroxyl silicone roj, epoxy hloov silicone roj, carboxyl hloov silicone roj, thiab lwm yam.
② Xim hloov thiab yellowing: Feem ntau tshwm sim los ntawm muaj cov amino pawg nyob rau hauv ib co qauv mos films thiab amino silicone roj. Hauv zaj duab xis muag, cationic soft film yog mos thiab muaj tes zoo. Nws yog ib qho yooj yim rau adsorb ntawm fabrics, tab sis nws yog nquag yellowing thiab discoloration, uas cuam tshuam rau hydrophilicity. Yog hais tias cationic mos zaj duab xis yog hloov mus rau hauv cov roj mos hmoov, nws yellowing yuav txo tau heev thiab hydrophilicity kuj yuav zoo dua. Piv txwv li, los ntawm kev sib xyaw cationic mos zaj duab xis nrog hydrophilic silicone roj los yog hydrophilic finishing agent, nws hydrophilicity yuav raug txhim kho.
Anionic lossis non-ionic films tsis ua rau yellowing, thiab qee cov yeeb yaj kiab tsis yellowing thiab tsis cuam tshuam rau hydrophilicity.
Amino silicone roj yog tam sim no feem ntau siv silicone roj, tab sis cov amino pawg tuaj yeem ua rau tsis muaj xim thiab daj. Qhov siab dua tus nqi ammonia, qhov ntau dua qhov yellowing. Tsawg yellowing amino silicone roj los yog polyether hloov, epoxy hloov silicone roj uas tsis tshua muaj yellowing yuav tsum tau siv xwb.
Tsis tas li ntawd, cationic surfactants xws li 1227, 1831 thiab 1631 yog qee zaum siv los ua emulsifiers hauv cov tshuaj pleev xim polymerization, uas yuav ua rau yellowing.
Kev siv cov emulsifiers sib txawv thaum lub sij hawm silicone roj emulsification ua rau txawv "xim stripping teebmeem", uas tuaj yeem ua rau xim stripping nyob rau hauv cov xwm txheej sib txawv thiab ua rau cov xim sib dua, uas twb tau txiav txim siab hloov xim.
③ Qhov txo qis hauv hydrophilicity ntawm cov ntaub yog feem ntau tshwm sim los ntawm cov teeb meem nrog cov qauv ntawm cov ntaub mos mos siv thiab tsis muaj dej nqus cov noob tom qab tsim cov roj silicone, nrog rau kev kaw cov dej nqus cov chaw xws li hydroxyl pawg ntawm cellulose fibers, carboxyl pawg, thiab cov amino pawg ntawm cov ntaub plaub, ua rau txo qis hauv dej nqus. Anionic thiab non-ionic soft films thiab hydrophilic hom silicone roj yuav tsum tau xaiv ntau li ntau tau.
④ Tsaus me ntsis: Qhov laj thawj tseem ceeb yog tias cov roj stains ntawm cov ntaub tsis tau tshem tawm tag nrho thaum kho ua ntej, thiab cov xim ntawm cov roj stains yog tsaus dua thaum dyeing; Los yog muaj npuas ntau dhau hauv cov dyeing da dej, thiab cov khoom sib xyaw ua npuas dej thiab cov tsho zoo nkauj, xim, thiab lwm yam yog stained ntawm cov ntaub; Los yog defoamer ntab roj ua rau cov roj tsaus; Los yog tar zoo li cov khoom nyob rau hauv dyeing vat sticking rau ntaub; Los yog dyes sib sau ua ke rau hauv cov xim tsaus nti hauv cov xwm txheej sib txawv; Los yog vim muaj calcium thiab magnesium ions ntau dhau hauv dej, uas khi nrog dyes thiab lo rau cov ntaub. Cov phiaj xwm kev kho mob yuav tsum tau ua, xws li ntxiv cov tshuaj degreasing rau refining thaum lub sij hawm kho ua ntej, siv cov uas tsis muaj foaming thiab tsis foaming dyeing agents, xaiv defoamers uas tsis nquag rau cov roj ntab, ntxiv chelating agents los txhim kho dej zoo, ntxiv solubilizing thiab dispersing. cov neeg sawv cev los tiv thaiv cov xim sib xyaw ua ke, thiab siv cov tshuaj ntxuav kom huv hauv lub tank kom raws sijhawm.
⑤ Lub teeb xim xim: Qhov laj thawj tseem ceeb yog qhov tsis sib xws ua ntej kev kho mob, nrog rau cov plaub hau tsis zoo hauv qee qhov chaw, ua rau muaj qee qhov kev tsis lees paub xim, lossis muaj cov tshuaj tsis zoo dye, lossis nrog calcium xab npum, magnesium xab npum, thiab lwm yam ntawm cov ntaub. Thaum lub sij hawm kho ua ntej los yog tsis sib xws txhob lo lo ntxhuav gloss, los yog tsis sib npaug ntawm ziab ntawm cov khoom semi-tiav, los yog cov khoom siv xws li undissolved elemental hmoov thiab dej qab zib tshauv ntawm lub ntaub nto, los yog dej ntws ua ntej ziab cov xim, los yog cov chaw pab cuam los ntawm kev kho tom qab xws li softening ntawm cov xim. Ib yam li ntawd, kev kho mob yog tsim nyog, xws li ntxiv dag zog rau kev kho mob ua ntej. Thaum xaiv cov khoom siv kho mob ua ntej, nws yog ib qho tsim nyog yuav tsum tsis txhob tsim cov calcium magnesium xab npum, thiab kev kho mob ua ntej yuav tsum zoo ib yam thiab tag nrho (uas muaj feem xyuam rau kev xaiv cov tshuaj refining agents, penetrating agents, chelating dispersants, sericulture penetrating agents, lwm yam). Yuanming hmoov, dej qab zib tshauv, thiab lwm yam yuav tsum tau ua kom zoo thiab muab tso rau hauv lub tank, thiab kev tswj xyuas kev ua haujlwm yuav tsum muaj zog.
⑥ Alkali me ntsis: Qhov laj thawj tseem ceeb yog qhov tshem tawm alkali tom qab kev kho mob ua ntej (xws li tshuaj dawb, txhob lo lo ntxhuav polishing) tsis huv lossis tsis sib xws, ua rau muaj cov pob alkali. Yog li ntawd, nws yog ib qho tsim nyog los ntxiv dag zog rau cov txheej txheem tshem tawm alkali ntawm cov txheej txheem ua ntej kho.
⑦ Cov tawv nqaij tawv:
Muaj ntau ntau qhov laj thawj rau qhov no:
ib. Cov khoom siv zaj duab xis tsis zoo, nrog thaiv zoo li tus softener adhering rau cov ntaub;
b. Muaj npuas ntau dhau tom qab cov yeeb yaj kiab yaj. Thaum cov ntaub tawm los ntawm lub vat, daim ntaub yog stained nrog softener ua npuas ncauj;
c. Cov dej tsis zoo, siab hardness, impurities hauv dej ua ke nrog cov softener thiab aggregate ntawm cov ntaub. Qee lub tsev lag luam txawm siv sodium hexametaphosphate los yog alum los kho cov dej, uas tsim cov flocs nrog impurities nyob rau hauv dej thiab tawm stains ntawm cov ntaub nto tom qab nkag mus rau softening da dej;
d. Cov ntaub yog coated nrog anionic tshuaj, uas ua ke nrog cationic softeners los tsim stains thaum softening ua, los yog cov ntaub yog coated nrog alkali, ua rau cov softeners aggregate;
e. Cov qauv ntawm softeners sib txawv, thiab qee qhov yuav ua rau lawv hloov los ntawm lub xeev emulsified mus rau ib qho slag zoo li cov khoom thiab ua raws li cov ntaub ntawm qhov kub thiab txias.
f. Muaj tar zoo li softeners thiab lwm yam khoom nyob rau hauv lub tog raj kheej uas poob tawm thiab lo rau ntawm daim ntaub.
⑧ Silicone roj stains: Qhov no yog hom stains nyuaj tshaj plaws los daws, feem ntau yog vim:
ib. Tus nqi pH ntawm cov ntaub yog tsis nruab nrab, tshwj xeeb tshaj yog thaum nws muaj alkali, ua rau cov roj silicone tawg thiab ntab;
b. Cov dej zoo ntawm chav da dej kho mob yog qhov tsis zoo thiab lub hardness siab dhau lawm. Silicone roj yog nquag roj ntab hauv dej nrog lub hardness ntau dua 150PPM;
c. Cov teeb meem zoo ntawm cov roj silicone muaj xws li tsis zoo emulsification (kev xaiv tsis zoo ntawm emulsifiers, cov txheej txheem tsis zoo emulsification, loj emulsified hais, thiab lwm yam), thiab tsis zoo shear kuj (tsuas yog vim qhov zoo ntawm silicone roj nws tus kheej, emulsification system, silicone roj ntau yam, silicone. cov txheej txheem roj synthesis, thiab lwm yam).
Koj tuaj yeem xaiv cov roj silicone uas tiv taus shear, electrolyte, thiab pH hloov, tab sis koj yuav tsum xyuam xim rau kev siv thiab ib puag ncig ntawm cov roj silicone. Koj tuaj yeem txiav txim siab xaiv cov roj silicone hydrophilic.
⑨ Tsis zoo fuzzing:
Cov fuzzing tsis zoo yog cuam tshuam nrog kev ua haujlwm ntawm lub tshuab fuzzing (xws li kev tswj nruj, fuzzing menyuam ceev, thiab lwm yam). Rau fuzzing, thaum thov softener (feem ntau hu ua waxing), tswj cov dynamic thiab zoo li qub kev sib txhuam coefficients ntawm cov ntaub yog qhov tseem ceeb. Yog li ntawd, lub formulation ntawm fuzzing softener yog ib qho tseem ceeb heev. Yog tias lub softener tsis siv kom raug, nws tuaj yeem ua rau tsis zoo fuzzing, thiab txawm tias ua rau tearing lossis hloov ntawm qhov rooj dav.
