1.Halayen amino silicone
Amino silicone yana da mahimman sigogi huɗu: ƙimar ammonia, danko, reactivity, da girman barbashi. Waɗannan sigogi guda huɗu suna nuna ingancin amino silicone kuma suna tasiri sosai ga salon masana'anta da aka sarrafa. Kamar jin hannu, fari, launi, da sauƙi na emulsification na silicone.
① darajar Ammoniya
Amino silicone yana ba da yadudduka tare da abubuwa daban-daban kamar taushi, santsi, da cikawa, galibi saboda ƙungiyoyin amino a cikin polymer. Ana iya wakilta abun ciki na amino ta ƙimar ammonia, wanda ke nufin milliliters na hydrochloric acid tare da daidaitaccen taro da ake buƙata don kawar da 1g na amino silicone. Saboda haka, darajar ammonia kai tsaye daidai da adadin tawadar da ke cikin amino acid a cikin man silicone. Mafi girman abun ciki na amino, mafi girman darajar ammonia, kuma mafi laushi da santsi na masana'anta da aka gama. Wannan saboda karuwa a cikin ƙungiyoyin aikin amino yana ƙara haɓaka alaƙarsu ga masana'anta, suna samar da tsari na yau da kullun na ƙwayoyin cuta da ba masana'anta laushi da laushi.
Duk da haka, hydrogen mai aiki a cikin rukunin amino yana da sauƙi ga oxidation don samar da chromophores, yana haifar da rawaya ko ɗan rawaya na masana'anta. Game da rukunin amino guda ɗaya, a bayyane yake cewa yayin da abun ciki na amino (ko ƙimar ammonia) ke ƙaruwa, yuwuwar oxidation yana ƙaruwa kuma launin rawaya yana ƙaruwa. Tare da karuwar darajar ammonia, polarity na amino silicone molecule yana ƙaruwa, wanda ke ba da buƙatu mai kyau don emulsification na amino silicone mai kuma ana iya sanya shi cikin micro emulsion. Zaɓin emulsifier da girman da rarraba girman barbashi a cikin emulsion kuma suna da alaƙa da ƙimar ammonia.
① Danko
Danko yana da alaƙa da nauyin kwayoyin halitta da rarraba nauyin kwayoyin halitta na polymers. Gabaɗaya magana, mafi girman danƙon shine, mafi girman nauyin kwayoyin halitta na amino silicone, mafi kyawun kayan samar da fim a saman masana'anta shine, mafi laushin ji, kuma santsi yana da kyau, amma mafi muni. permeability shine. Musamman ga yadudduka masu murƙushewa da kyawawan yadudduka masu ƙima, amino silicone yana da wahalar shiga cikin fiber na ciki, yana shafar aikin masana'anta. Maɗaukakin danko kuma zai sa zaman lafiyar emulsion ya fi muni ko da wahala a yi micro emulsion. Gabaɗaya, aikin samfur ba za'a iya daidaita shi ta ɗanko kawai ba, amma galibi ana daidaita shi ta ƙimar ammonia da ɗanko. Yawancin lokaci, ƙananan ƙimar ammonia suna buƙatar babban danko don daidaita laushin masana'anta.
Don haka, santsin hannu yana buƙatar babban danko amino modified silicone. Duk da haka, a lokacin sarrafa taushi da yin burodi, wasu amino silicone giciye don samar da fim, ta haka yana ƙara nauyin kwayoyin halitta. Saboda haka, farkon nauyin kwayoyin halitta na amino silicone ya bambanta da nauyin kwayoyin halitta na amino silicone wanda a ƙarshe ya samar da fim a kan masana'anta. Sakamakon haka, santsin samfurin ƙarshe na iya bambanta sosai lokacin da ake sarrafa amino silicone iri ɗaya ƙarƙashin yanayin tsari daban-daban. A gefe guda kuma, ƙananan danko amino silicone kuma na iya inganta nau'in yadudduka ta hanyar ƙara abubuwan haɗin giciye ko daidaita yanayin yin burodi. Low danko amino silicone ƙara permeability, kuma ta hanyar giciye jamiái da kuma aiwatar da ingantawa, da abũbuwan amfãni daga high da low danko amino silicone za a iya hade. Matsakaicin danko na al'ada amino silicone yana tsakanin 150 zuwa 5000 centipoise.
Koyaya, yana da mahimmanci a lura cewa rarraba nauyin kwayoyin halitta na amino silicone na iya yin tasiri mafi girma akan aikin samfur. Ƙananan nauyin kwayoyin halitta yana shiga cikin fiber, yayin da babban nauyin kwayoyin halitta yana rarraba a saman farfajiyar fiber ɗin, ta yadda ciki da waje na fiber suna nade da amino silicone, yana ba da masana'anta mai laushi da santsi, amma matsala na iya zama cewa kwanciyar hankali na micro emulsion zai shafi idan bambancin nauyin kwayoyin halitta ya yi girma.
① Reactivity
Amino silicone mai amsawa zai iya haifar da haɗin kai yayin kammalawa, kuma haɓaka matakin haɗin giciye zai ƙara santsi, laushi, da cikar masana'anta, musamman dangane da haɓakar elasticity. Tabbas, lokacin amfani da abubuwan haɗin giciye ko haɓaka yanayin yin burodi, amino silicone na gabaɗaya shima zai iya haɓaka digiri na haɗin giciye don haka inganta haɓakawa. Amino silicone tare da ƙarshen hydroxyl ko methylamino, mafi girman darajar ammonia, mafi kyawun digirin haɗin kai, kuma mafi kyawun ƙarfin sa.
② Girman sashi na micro emulsion da cajin lantarki na emulsion
The barbashi Girman amino silicone emulsion ne karami, kullum kasa 0.15 μ, don haka emulsion ne a cikin wani thermodynamic barga watsawa jihar. Its ajiya kwanciyar hankali, zafi kwanciyar hankali da karfi da kwanciyar hankali ne m, kuma shi kullum ba ya karya da emulsion. A lokaci guda, ƙaramin girman barbashi yana ƙara saman yanki na barbashi, haɓaka sosai da yiwuwar tuntuɓar silinilone da masana'anta. Ƙarfin adsorption na saman yana ƙaruwa kuma daidaito yana inganta, kuma haɓaka yana inganta. Sabili da haka, yana da sauƙi don samar da fim mai ci gaba, wanda ke inganta laushi, laushi, da cikar masana'anta, musamman don ƙarancin ƙima. Duk da haka, idan girman rabon barbashi na amino silicone bai dace ba, kwanciyar hankali na emulsion zai yi tasiri sosai.
Cajin amino silicone micro emulsion ya dogara da emulsifier. Gabaɗaya, filayen anionic suna da sauƙin tallata cationic amino silicone, ta haka inganta tasirin magani. Tallace-tallacen emulsion na anionic ba abu ne mai sauƙi ba, kuma ƙarfin adsorption da daidaituwa na emulsion wanda ba na ionic ba ya fi anionic emulsion. Idan mummunan cajin fiber yana da ƙananan, tasiri akan nau'o'in cajin daban-daban na micro emulsion zai ragu sosai. Saboda haka, sinadarai zaruruwa kamar polyester sha daban-daban micro emulsion tare da daban-daban cajin da kuma uniformity ya fi auduga zaruruwa.
1.Tasirin amino silicone da kaddarorin daban-daban akan hannun-ji na yadudduka
① Taushi
Ko da yake an inganta halayen amino silicone sosai ta hanyar ɗaure ƙungiyoyin amino aiki zuwa yadudduka, da kuma tsarin tsari na silicone don ba da yadudduka mai laushi da santsi. Koyaya, ainihin tasirin ƙarewa ya dogara ne akan yanayi, yawa, da rarraba ƙungiyoyin ayyukan amino a cikin amino silicone. A lokaci guda, da dabara na emulsion da talakawan barbashi girman emulsion kuma rinjayar taushi ji. Idan abubuwan da suka shafi abubuwan da ke sama za su iya cimma daidaito mai kyau, salon laushi na ƙare masana'anta zai kai ga mafi kyawunsa, wanda ake kira "super soft". Darajar ammonia na gabaɗaya amino silicone softeners yawanci tsakanin 0.3 da 0.6. Mafi girman darajar ammonia, mafi yawan rarraba ayyukan amino a cikin siliki, kuma mafi laushin masana'anta yana jin. Duk da haka, lokacin da darajar ammonia ya fi 0.6, jin daɗin laushi na masana'anta ba ya karuwa sosai. Bugu da kari, da karami da barbashi size na emulsion, da more conducive zuwa manne da emulsion da taushi ji.
② Santsi hannun hannu
Saboda yanayin tashin hankali na fili na silicone yana da ƙanƙanta, amino silicone micro emulsion yana da sauƙin yadawa akan farfajiyar fiber, yana samar da kyakkyawan santsi. Gabaɗaya magana, ƙarami ƙimar ammonia kuma mafi girman nauyin kwayoyin halitta na amino silicone, mafi kyawun santsi. Bugu da kari, silicone da aka dakatar da amino zai iya samar da kyakkyawan tsari na jagora saboda duk atom na siliki a cikin hanyoyin haɗin sarkar da ake haɗa su da rukunin methyl, yana haifar da kyakkyawan jin daɗin hannu.
