nkhani

Asidi ya Butylnaphtalenesulfonic ndi mchere wa sodium(Sodium 2-butyl-1-naphthalenesulfonate), CAS 25638-17-9, yomwe imadziwikanso kuti Pelex NB, NekalBX, ndi anionic surfactant. Butylnaphtalenesulfonic acid sodium salt imagwiritsidwa ntchito kwambiri m'mafakitale ndi kupanga zinthu zosiyanasiyana. Tiyeni tiwone izi kuchokera m'mbali zotsatirazi.

Chidziwitso choyambira

Dzina la malonda: Butylnaphtalenesulfonic Acid Sodium Salt

Fomula ya maselo: C14H15NaO2S

Kulemera kwa maselo: 286.32

Zina zomwe zimatchedwanso: Pelex NB; NekalBX; sodium butylnaphthalenesulfonate; Butylnaphthalenesulfonic acid sodium salt; Sodium 2-butyl-1-naphthalenesulfonate; Sodium 4-butylnaphthalene-1-sulfonate

Mawonekedwe: Ufa woyera pang'ono kapena wachikasu pang'ono.

Kusungunuka: Kusungunuka mosavuta m'madzi.

Kukhazikika: Asidi ya butylnaphtalenesulfonic ndi mchere wa sodium womwe umakhala wokhazikika ku ma acid, ma bases ndi madzi olimba. Pamene chinthu cholimbacho chitenthedwa kufika pa 110℃, sichisungunuka koma chimapanga mpweya wa carbon ndikutulutsa nthunzi ya alkaline.

Mawonekedwe a magwiridwe antchito

Sodium butylnaphthalene sulfonate (CAS 25638-17-9() ndi anionic surfactant yabwino kwambiri yokhala ndi mphamvu zolowa, kunyowetsa, kusakaniza, kufalitsa ndi kutulutsa thovu. Sodium 4-butylnaphthalene-1-sulfonate imagwira ntchito bwino pankhani yolimbana ndi asidi, kukana alkali, kukana madzi olimba komanso kukana mchere wosapangidwa. Kuwonjezera mchere pang'ono patebulo kungapangitse kuti mphamvu yake yolowa iwonjezere kwambiri.

Kuchuluka kwa mpweya wabwino kwambiri

Kuphatikiza kwa "butyl hydrophobic chain + naphthalene ring + sodium sulfonate hydrophilic group" mu kapangidwe ka molekyulu kumatha kulowa mwachangu m'mipata kapena zigawo za sera pamwamba pa zinthu zolimba monga ulusi, nsalu, ndi tinthu ta pigment. Makamaka m'zochitika monga kuchotsa kukula kwa nsalu ndi kupopera mankhwala ophera tizilombo, sodium 2-butyl-1-naphthalenesulfonate imatha kufupikitsa kwambiri nthawi yolowera ya yankho lochizira (mwachitsanzo, mu njira zogwirira nsalu, butylnaphtalenesulfonic acid sodium salt ingalole yankho lopukuta kulowa mkati mwa nsalu mkati mwa mphindi 1-3). Komanso, mutawonjezera mchere pang'ono, mphamvu yolowera imatha kuwonjezeka ndi 30% mpaka 50%, yomwe ndi mwayi wake wapadera kuposa zina zolowera.

Kunyowa kwambiri

Mchere wa sodium wa butylnaphtalenesulfonic acid ukhoza kufalitsa madzi mwachangu kapena madzi osungunuka pamwamba pa malo osagwirizana ndi madzi (monga ulusi wa nsalu, masamba a mbewu, ndi malo obiriwira) kuti apange filimu yonyowa yofanana, kupewa "kuchulukana kwa madontho" - mwachitsanzo, mumakampani opanga mapepala, NekalBX imatha kufalitsa ulusi wa pulp mofanana m'madzi, kuchepetsa zolakwika zofanana za pepala zomwe zimachitika chifukwa cha kuchulukana kwa ulusi. Mu zokutira, Pelex NB ingathandize zinthu zoyambira kunyowetsa tinthu ta utoto, ndikuyika maziko a kufalikira pambuyo pake.

Kapangidwe kabwino ka emulsifying ndi dispersing

Katundu wopangira emulsifying:NekalBXakhoza kufalitsa mafuta mosasunthika (monga zosakaniza zophera tizilombo, ma monomers a rabara) m'madzi kuti apange emulsion yofanana (mwachitsanzo, atachepetsa mphamvu ya mankhwala ophera tizilombo ndi madzi, sodium 2-butyl-1-naphthalenesulfonate imatha kusungidwa kwa maola opitilira 4 popanda kugawa).

Kufalikira: Mchere wa sodium wa butylnaphtalenesulfonic acid uli ndi mphamvu yabwino yofalitsa ndi kukhazikika pa tinthu tolimba (monga utoto ndi utoto), ndipo umatha kuletsa kusonkhana kwa tinthu. Mwachitsanzo, popaka utoto ndi kusindikiza, umatha kusunga tinthu ta utoto pa kukula kofanana kwa tinthu ta 1-5μm, kupewa kupezeka kwa "mtundu wosalala" panthawi yopaka utoto.

Kapangidwe ka thovu pang'ono

Pa nthawi yosakaniza kapena kutsanulira madzi, thovu linalake lidzapangidwa. Thovu lingathandize kuletsa tinthu tolimba (monga zodzaza popanga mapepala), koma kukhazikika kwa thovu kumakhala kocheperako (sikophweka kupanga "thovu lakufa" lomwe ndi lovuta kuchotsa), ndipo palibe chifukwa chowonjezera kuchuluka kwa defoamer pambuyo pake. Butylnaphtalenesulfonic acid sodium salt imaganizira zonse "zothandizira kuyimitsa" komanso "zosavuta kuchiza pambuyo pake".

Ntchito zazikulu

1. Malo osindikizira ndi kupaka utoto nsalu (malo ofunikira kwambiri)

Umu ndi momwe mchere wa sodium wa butylnaphtalenesulfonic acid umagwiritsidwira ntchito, womwe umagwira ntchito ngati cholowetsa madzi, chonyowetsa komanso chothandizira kupaka utoto:

Njira Yokonzera Zinthu: Powonjezerapo panthawi yochotsa kukula, kupukuta, kuyika kaboni, kusonkhanitsa, kuyika chlorination ndi njira zina za nsalu, sodium 4-butylnaphthalene-1-sulfonate imatha kuchepetsa msanga mphamvu ya pamwamba pa madzi, zomwe zimathandiza kuti madzi oyeretsa (monga madzi oyeretsa, madzi oyeretsa) alowe bwino mkati mwa ulusi wa nsalu, ndikuwonjezera mphamvu yochotsera zinyalala (monga kukula, sera), komanso kupewa zolakwika mu nsalu chifukwa cha kusakonzedwa bwino.

Njira yopaka utoto/kusindikiza: Monga chosungunulira utoto komanso chopaka utoto pamodzi,Pelex NBZingathandize kusungunula ndi kufalikira kwa utoto m'madzi, zimathandiza utoto kumamatira mofanana ku ulusi, kuchepetsa mikwingwirima yamitundu ndi mavuto osiyanasiyana amitundu, ndipo ndizoyenera kwambiri kupaka utoto wa ulusi wachilengedwe monga thonje ndi nsalu, komanso nsalu zosakanikirana.

Njira yochizira pambuyo pa chithandizo: Kuthandiza zinthu zomalizitsa (monga zinthu zoletsa makwinya ndi zofewetsa) kuti zilowe mkati kuti zitsimikizire kuti zotsatira zake zimaphimba nsalu mofanana.

2. Munda wa zophimba, inki ndi zomatira

Amagwiritsidwa ntchito kwambiri ngati dispersant:

Pakupanga utoto, zophimba ndi inki zochokera m'madzi, kuwonjezera sodium butylnaphthalene sulfonate kumatha kufalitsa mofanana utoto (monga titanium dioxide ndi carbon black) ndi zodzaza mu zinthu zoyambira, kuletsa kusonkhana kwa utoto, kukonza kukhazikika, kufanana kwa mitundu ndi kusinthasintha kwa zophimba/inki, komanso nthawi yomweyo kupewa kusungunuka ndi kugawikana kwa utoto panthawi yosungira.

Pokonzekera zomatira, mchere wa sodium wa butylnaphtalenesulfonic acid ukhoza kupititsa patsogolo kufalikira kwa ma resin ndi zodzaza, ndikuwonjezera mphamvu yolumikizana ndi kukhazikika kwa zomatira.

3. Makampani opanga mapepala

Monga chonyowetsa ndi chotulutsira madzi:

Pa nthawi yokonzekera zamkati, mchere wa sodium wa butylnaphtalenesulfonic acid umathandiza mankhwala (monga mankhwala oyeretsera, mankhwala ophikira) kulowa mwachangu mu ulusi wa zamkati, ndikuwonjezera luso lokonza;

Pa nthawi yopanga mapepala, butylnaphtalenesulfonic acid sodium salt 25638-17-9 imathandiza kuti ulusi ndi zinthu zodzaza (monga calcium carbonate, talcum powder) zisamafalikire, zimachepetsa kuchuluka kwa ulusi, komanso zimapangitsa kuti pepalalo likhale lofanana, lolimba komanso losalala pamwamba.

4. Munda wa mankhwala ophera tizilombo

Monga chowonjezera cha mankhwala ophera tizilombo (cholowetsa, chosakaniza):

Powonjezera mankhwala ophera tizilombo, mankhwala ophera udzu ndi fungicides m'madzi, Pelex NB imatha kunyowetsa ndi kulowetsa mankhwala amadzimadzi pamwamba pa mbewu (kapena pamwamba pa udzu ndi tizilombo), kuswa phula la khungu la mbewu, kulola zosakaniza zogwira ntchito kulowa mwachangu pamalo omwe mukufuna, kuonjezera kuchuluka kwa momwe mankhwala ophera tizilombo amagwiritsidwira ntchito komanso mphamvu yowongolera, komanso kuchepetsa zinyalala zomwe zimachitika chifukwa cha "kutuluka" kwa mankhwala amadzimadzi.

5. Magawo ena a mankhwala a mafakitale ndi a tsiku ndi tsiku

Makampani opanga rabara: Sodium 2-butyl-1-naphthalenesulfonate imagwira ntchito ngati emulsifier pokonzekera ma phala a rabara (monga rabara lachilengedwe ndi latex ya rabara yopangidwa), kuthandiza tinthu ta rabara kuti tifalikire mofanana m'madzi, kukulitsa kukhazikika kwa latex, komanso kuthandizira kukonza pambuyo pake (monga kuphimba ndi kuumba).

Mu mankhwala a tsiku ndi tsiku: Butylnaphtalenesulfonic acid, mchere wa sodium umagwiritsidwa ntchito pang'ono mu sopo ndi zotsukira kuti uthandize kukulitsa mphamvu yochotsa kuipitsidwa. Kapena ungagwiritsidwe ntchito ngati emulsifier mu zodzoladzola zina (monga mafuta odzola ndi mafuta) kuti ukhale wofanana komanso wokhazikika wa kapangidwe ka mankhwalawo.

Ndife akatswiri opanga zinthu zopangira mankhwala ndipo takhala tikugwira ntchito yopanga zinthubutylnaphtalenesulfonic acid mchere wa sodiumkwa zaka pafupifupi makumi awiri. Ngati mukufuna chinthu ichi, chonde titumizireni nthawi iliyonse.
