① Ayikwazi ukufeza umuzwa ofisayo wokuthinta: Isitayela esithambile sokuqedela okuthambile siyahlukahluka kuye ngezidingo zekhasimende, njengokuthambile, ukushelela, ukuthambile, ukuthambisa, uwoyela, ukoma, njll. Izithambisa ezihlukene zikhethwa ngokuya ngezitayela ezahlukene. Emafilimini athambile, kunezinhlaka ezahlukene zamafilimu athambile athambile, anamazinga ahlukene okuthamba, ama-fluffiness, abushelelezi, aphuzi, futhi athinta ukumuncwa kwamanzi kwezindwangu; Kuwoyela we-silicone, izakhiwo zamafutha abicah aguquliwe anezakhi zofuzo ezihlukile zokuguqulwa nazo zihlukile, njengamafutha a-amino silicone, uwoyela we-silicone we-hydroxyl, uwoyela we-epoxy modified silicone, uwoyela we-silicone oguquliwe we-carboxyl, njll.
② Ukushintsha umbala nokubaphuzi: Ngokuvamile kubangelwa ukuba khona kwamaqembu e-amino kumafilimu athile athambile ahlelekile namafutha a-amino asilicone. Kwifilimu ethambile, ifilimu ethambile ye-cationic ithambile futhi inokuzwakala kahle kwesandla. Kulula ukukhangisa ezindwangu, kodwa ijwayele ukuphuzi nokushintsha umbala, okuthinta i-hydrophilicity. Uma ifilimu elithambile le-cationic liguqulwa libe yimpushana kawoyela ethambile, ukuphuzi kwayo kuzoncipha kakhulu futhi i-hydrophilicity nayo izothuthukiswa. Isibonelo, ngokuhlanganisa ifilimu ethambile ye-cationic namafutha e-silicone e-hydrophilic noma i-hydrophilic finishing agent, i-hydrophilicity yayo izothuthukiswa.
Amafilimu e-anionic noma angewona awe-ionic awajwayele ukuphuzi, futhi amanye amafilimu awaphuzi futhi awathinti i-hydrophilicity.
Uwoyela we-amino silicone okwamanje ungawoyela we-silicone osetshenziswa kakhulu, kodwa amaqembu e-amino angabangela ukushintsha kombala nokuphuzi. Lapho inani le-ammonia liphakeme, liba likhulu ukuphuzi. Uwoyela we-amino silicone ophuzi ophansi noma i-polyether eshintshiwe, uwoyela we-silicone oshintshiwe we-epoxy ongajwayele ukuphuzi kufanele usetshenziswe esikhundleni salokho.
Ngaphezu kwalokho, ama-cationic surfactants afana no-1227, 1831 kanye no-1631 ngezinye izikhathi asetshenziswa njengama-emulsifiers ku-lotion polymerization, okuzophinde kubangele ukuphuzi.
Ukusetshenziswa kwama-emulsifiers ahlukene phakathi ne-silicone emulsification yamafutha kubangela "imiphumela yokuhlubula imibala" ehlukene, engabangela ukuhlubuka kombala ngaphansi kwezimo ezihlukene futhi kubangele umbala okhanyayo, osevele uthathwa njengoshintsho lombala.
③ Ukwehla kwe-hydrophilicity yezindwangu ngokuvamile kubangelwa izinkinga ngesakhiwo sefilimu ethambile esetshenziswayo kanye nokuntuleka kwezakhi zofuzo ezimunca amanzi ngemuva kokwakhiwa kwefilimu kawoyela we-silicone, kanye nokuvalwa kwezikhungo ezimunca amanzi ezifana namaqembu e-hydroxyl ku-cellulose fibers, amaqembu e-carboxyl, namaqembu e-amino eboyeni, okuholela ekwehleni kokumuncwa kwamanzi. Amafilimu athambile e-anionic kanye ne-non-ionic kanye nezinhlobo ze-hydrophilic zamafutha abicah kufanele akhethwe ngangokunokwenzeka.
④ Izindawo ezimnyama: Isizathu esiyinhloko ukuthi amabala kawoyela endwangu awazange asuswe ngokuphelele ngesikhathi sokwelashwa kwangaphambili, futhi umbala wamabala kawoyela wawumnyama ngesikhathi sokudaya; Noma kukhona igwebu eliningi kakhulu ekugezeni kokudaya, futhi ingxube ye-foam ne-sweater fancy, idayi, njll ingcoliswe kwendwangu; Noma amafutha antantayo e-defoamer abangela amabala amnyama amafutha; Noma itiyela njengezinto eziku-vat yokudaya ezinamathele endwangu; Noma odayi bahlanganisa amabala anombala omnyama ngaphansi kwezimo ezihlukene; Noma ngenxa ye-calcium eningi ne-magnesium ion emanzini, abopha ngodayi futhi anamathele ezindwangu. Ukwelashwa okuhlosiwe kufanele kwenziwe, njengokwengeza ama-agent okwehlisa amafutha okucwenga ngesikhathi sokwelashwa kwangaphambili, ukusebenzisa ama-ejenti okudaya amagwebu aphansi futhi angaphumi amagwebu, ukukhetha ama-defoam angajwayele ukuntanta uwoyela, ukwengeza ama-chelating agents ukuthuthukisa izinga lamanzi, ukwengeza ama-solubilizing kanye nama-agent ahlakazayo ukuvimbela ukuhlanganisa udayi ngendlela yokuhlanza, nokusebenzisa ama-agent okuhlanza isikhathi sokuhlanza.
⑤ Amabala anombala okhanyayo: Isizathu esiyinhloko ukungalingani kokwelashwa kwangaphambili, okunomthelela omubi wezinwele kwezinye izindawo, okuholela ezingeni elithile lokwenqatshwa kodayi, noma ukuqukatha izinto ezilahlwa udayi, noma ngensipho ye-calcium, insipho ye-magnesium, njll. endwangu ngesikhathi sokwelashwa kwangaphambili noma isicwebezelisi sikasilika esingalingani, noma ukomiswa okungalingani njengezinhlayiyana ezingaqediwe noma i-soda engaqediwe. indawo yendwangu, noma amanzi aconsayo ngaphambi kokoma udayi, noma izindawo ezisizayo ezibangelwa ukwelashwa ngemva kokwelashwa njengokuthambisa udayi. Ngokufanayo, ukwelashwa okuhlosiwe kuyadingeka, njengokuqinisa ukwelashwa kwangaphambili. Lapho ukhetha izithasiselo zokwelashwa zangaphambi kokwelashwa, kuyadingeka ukugwema ukwakheka kwensipho ye-calcium magnesium, futhi ukwelashwa kwangaphambilini kufanele kube okufanayo futhi kuphelele (okuhlobene nokukhethwa kwama-ejenti okuhlanza, ama-ejenti angenayo, ama-dispersants we-chelating, ama-sericulture penetrating agents, njll.). I-Yuanming powder, i-soda ash, njll. kumele kucutshungulwe kahle futhi kufakwe ethangini, futhi umsebenzi wokuphatha ukukhiqiza kumele uqiniswe.
⑥ Amabala e-alkali: Isizathu esiyinhloko ukuthi ukususwa kwe-alkali ngemva kokwelashwa kwangaphambili (njengokufiphalisa, ukupholisha usilika) akuhlanzekile noma akufani, okuholela ekwakhekeni kwamabala e-alkali. Ngakho-ke, kuyadingeka ukuqinisa inqubo yokususwa kwe-alkali yenqubo yokwelashwa kwangaphambili.
⑦ Ibala elithambile:
Kunezizathu ezimbalwa ezingenza lokhu:
a. Impahla yefilimu ethambile empofu, enentofontofo emise okwebhlokhi enamathela endwangu;
b. Kukhona igwebu eliningi ngemva kokuba ifilimu isincibilikile. Lapho indwangu iphuma ku-vat, indwangu ingcoliswe igwebu elithambile;
c. Izinga lamanzi elibi, ubulukhuni obuphezulu, ukungcola emanzini kuhlangana ne-softener kanye nokuhlanganisa endwangu. Amanye amafekthri aze asebenzise i-sodium hexametaphosphate noma i-alum ukwelapha amanzi, okwenza ama-flocs anokungcola emanzini futhi ashiye amabala ebusweni bendwangu ngemva kokungena okugeza okuthambisayo;
d. Indwangu ihlanganiswe nezinto ze-anionic, ezihlanganisa nezithambile ze-cationic ukuze zenze amabala ngesikhathi sokucubungula ukuthambisa, noma indwangu ihlanganiswe ne-alkali, okwenza ukuthi izithambisa zihlangane;
e. Isakhiwo sezinto ezithambisayo siyahlukahluka, futhi ezinye zingase zibangele ukuthi zishintshe ukusuka kusimo se-emulsified zibe into efana ne-slag futhi zinamathele ezindwangu emazingeni okushisa aphezulu.
f. Kukhona itiyela elifana nezinto ezithambisayo nezinye izinto kusilinda eziwayo bese zinamathela endwangu.
⑧ Amabala kawoyela we-Silicone: Lolu uhlobo olunzima kakhulu lwamabala ukuphatha, ikakhulukazi ngenxa:
a. Inani le-pH lendwangu alithathi hlangothi, ikakhulukazi uma liqukethe i-alkali, okwenza ukuba amafutha abicah aphule futhi antante;
b. Izinga lamanzi lokugeza lokuhlanza liphansi kakhulu futhi ubulukhuni buphezulu kakhulu. Amafutha e-Silicone athambekele ekubeni amafutha antanta emanzini anobunzima obukhulu kuno-150PPM;
c. Izinkinga zekhwalithi zamafutha abicah zifaka phakathi i-emulsification engalungile (ukukhethwa okungalungile kwama-emulsifiers, inqubo ye-emulsification engalungile, izinhlayiya ezinkulu ze-emulsified, njll.), kanye nokungazweli kahle kwe-shear (ikakhulukazi ngenxa yekhwalithi yamafutha abicah ngokwawo, uhlelo lwe-emulsification, izinhlobonhlobo zamafutha a-silicone, inqubo yokuhlanganisa uwoyela we-silicone, njll.).
Ungakhetha uwoyela we-silicone amelana ne-shear, i-electrolyte, ne-pH izinguquko, kodwa kufanele unake ukusetshenziswa nendawo kawoyela we-silicone. Ungase futhi ucabange ukukhetha uwoyela we-silicone we-hydrophilic.
⑨ Ukungaboni kahle:
I-fuzzing engalungile ihlobene eduze nokusebenza komshini wokufiphaza (njengokulawula ukushuba, isivinini se-roller efifizayo, njll.). Ngokuhlanganisa, uma usebenzisa isithambisa (esivame ukwaziwa ngokuthi i-waxing), ukulawula ama-coefficients ashukumisayo namile endwangu kuwukhiye. Ngakho-ke, ukwakhiwa kwe-fuzzing softener kubalulekile. Uma isithambisi singasetshenziswa kahle, singabangela ngokuqondile ukungezwani kahle, futhi kuholele nasekudabukeni noma ekushintsheni kobubanzi bomnyango.
