Kugadzikana: Butylnaphtalenesulfonic acid sodium salt inogadzikana zvakanyanya kune acids, bases uye mvura yakaoma. Kana chinhu chakaoma chikapiswa kusvika 110℃, hachinyungudike asi chinoita carbonize uye chinoburitsa alkaline vapor.
Maitiro ekushanda
Sodium butylnaphthalene sulfonate (CAS 25638-17-9) imushonga weanionic surfactant wakanaka une hunhu hwakanaka hwekupinda, kunyorovesa, kusanganisa, kupararira uye kuburitsa furo. Sodium 4-butylnaphthalene-1-sulfonate inoshanda zvakanaka panyaya yekudzivirira acid, alkali, mvura yakaoma uye inorganic salt. Kuwedzera munyu mudiki wetafura kunogona kuwedzera simba rayo rekupinda.
Kupinda kwemvura kwakanakisa
Kusanganiswa kwe "butyl hydrophobic chain + naphthalene ring + sodium sulfonate hydrophilic group" muchimiro chemamorekuru kunogona kupinda nekukurumidza mumaburi kana ma layers ane wax pamusoro pezvinhu zvakasimba zvakaita sefibers, machira, uye pigment particles. Kunyanya mumamiriro ezvinhu akadai sekubvisa saizi yemachira uye kupfapfaidza mishonga inouraya zvipembenene, sodium 2-butyl-1-naphthalenesulfonate inogona kupfupisa zvakanyanya nguva yekupinda kwemushonga wekurapa (semuenzaniso, mumabasa emachira, butylnaphtalenesulfonic acid sodium salt inogona kubvumira mushonga wekukwesha kupinda mukati mejira mukati memaminitsi 1-3). Uyezve, mushure mekuwedzera munyu mudiki, simba rekupinda rinogona kuwedzerwa ne30% kusvika 50%, inova mukana wayo wakasiyana pane mamwe mapenetrants.
Kunyorova kwakanyanya
Munyu we sodium weButylnaphtalenesulfonic acid unogona kukurumidza kuparadzira mvura kana mvura inonyungudutsa pamusoro pemvura inonyungudutsa (senge machira ejira, mashizha ezvirimwa, uye pamusoro pe pigment) kuti ugadzire firimu rinonyorovesa zvakafanana, kudzivirira chiitiko che "droplet agglomeration" - semuenzaniso, muindasitiri yekugadzira mapepa, NekalBX inogona kuparadzira ma pulp fibers zvakaenzana mumvura, zvichideredza kusakwana kwemapepa kunokonzerwa ne fiber agglomeration. Mukuputira, Pelex NB inogona kubatsira pasi pezvinhu kunyorovesa zvidimbu zve pigment, zvichiisa hwaro hwekupararira kunotevera.
Hunhu hwakanaka hwekusanganisa uye kuparadzira
Hunhu hwe emulsifying:NekalBXinogona kuparadzira mafuta zvakanaka (semushonga wezvipembenene, rabha monomers) muchikamu chemvura kuti igadzire emulsion yakafanana (semuenzaniso, mushure mekusanganisa mushonga wezvipembenene nemvura, sodium 2-butyl-1-naphthalenesulfonate inogona kugara kwemaawa anopfuura mana isina kupatsanurwa).
Kupararira: Butylnaphtalenesulfonic acid sodium salt ine simba rakanaka rekuparadzanisa uye kudzikamisa zvidimbu zvakasimba (zvakadai semadhayi nependi), uye inogona kudzivirira kuunganidzana kwezvidimbu. Semuenzaniso, mukudhaya nekudhinda, inogona kuchengetedza zvidimbu zvedhayi pahukuru hwakaenzana hwe1-5μm, ichidzivirira kuitika kwe "mavara anotsvedza" panguva yekudhaya.
Hunhu hwemafuro ari pakati nepakati
Munguva yekukurunga kana kuyerera kwemvura, furo rinogadzirwa. Furo rinogona kubatsira mukunamira zvidimbu zvakasimba (sezvinozadza mukugadzira mapepa), asi kugadzikana kwefuro kuri pakati nepakati (hazvisi nyore kugadzira "mabubble akafa" akaoma kubvisa), uye hapana chikonzero chekuwedzera huwandu hwakawanda hwe defoamer gare gare. Butylnaphtalenesulfonic acid sodium salt inofunga nezve "suspension assistance" uye "nyore kwekurapwa kunotevera".
Mashandisirwo makuru
1. Munda wekudhinda nekudhaya machira (munda wekushandisa wakakosha)
Iyi ndiyo nzira huru yekushandisa butylnaphtalenesulfonic acid sodium salt, iyo inonyanya kushanda semushonga wekupinda, wetisa uye mubatsiri wekudhaya:
Maitiro ekugadzirisa: Kana yawedzerwa panguva yekubvisa saizi, kukwesha, kuisa carbonization, kuunganidzwa, chlorination nedzimwe nzira dzemachira, sodium 4-butylnaphthalene-1-sulfonate inogona kuderedza kushushikana kwemvura nekukurumidza, zvichiita kuti mvura yekurapa (yakadai sekubvisa saizi, mvura yekuchenesa) ipinde zvakanaka mukati mefaibha dzemachira, zvichivandudza kushanda zvakanaka kwetsvina (yakadai sehukuru, wakisi), uye panguva imwe chete ichidzivirira zvikanganiso mumachira nekuda kwekusagadziriswa kwakaenzana.
Maitiro ekudhaya/kudhinda: Semushonga wekubatanidza dhayi uye musanganiswa wekubatanidza dhayi,Pelex NBinogona kuvandudza kunyungudika uye kupararira kwemadhayi mumvura, kubatsira madhayi kunamira zvakaenzana kune machira, kuderedza mitsetse yemavara nematambudziko ekusiyana kwemavara, uye inonyanya kukodzera kudhaya machira echisikigo akadai sedonje nerineni, pamwe nemachira akasanganiswa.
Maitiro ekurapa mushure mekurapwa: Batsirai zvinhu zvinopedza basa (zvakaita sezvinhu zvinodzivirira makwinya uye zvinopfavisa) kuti zvipinde mukati mejira kuti zvive nechokwadi chekuti mhedzisiro yekupedzisa inofukidza jira zvakaenzana.
2. Nzvimbo yekuputira, inki uye zvinonamira
Inonyanya kushandiswa semuchina wekuparadzira:
Mukugadzirwa kwependi, machira emvura uye inki, kuwedzerwa kwe sodium butylnaphthalene sulfonate kunogona kuparadzira pigments zvakaenzana (senge titanium dioxide ne carbon black) uye fillers mu base material, kudzivirira pigment agglomeration, kunatsiridza kugadzikana, kufanana kwemavara uye kuenzana kwe coatings/inks, uye panguva imwe chete kudzivirira sedimentation uye stratification panguva yekuchengetera.
Mukugadzirira maglues, butylnaphtalenesulfonic acid sodium salt inogona kuvandudza kupararira kwemaresins nemafillers, uye kuwedzera simba rekubatanidza uye kugadzikana kwemaglues.
3. Indasitiri yekugadzira mapepa
Semushonga wekunyorovesa uye wekunyungudutsa:
Padanho rekugadzirira pulp, butylnaphtalenesulfonic acid sodium salt inobatsira mishonga yemakemikari (yakadai sebleaching agents, cooking agents) kupinda nekukurumidza mu pulp fibers, zvichivandudza mashandiro ekugadzirisa;
Munguva yekugadzira bepa, butylnaphtalenesulfonic acid sodium salt 25638-17-9 inovandudza kupararira kwefibers ne fillers (senge calcium carbonate, talcum powder), inoderedza fiber agglomeration, uye inowedzera kufanana, simba uye kutsetseka kwepepa.
4. Munda wezvipembenene
Semushonga wezvipembenene (penetrant, emulsifier):
Kana ikaiswa mukugadzira emulsions kana mishonga yekuuraya zvipembenene, mishonga yekuuraya zvipembenene, uye mishonga yekuuraya zvipembenene, Pelex NB inogona kuwedzera kugona kwemushonga wemvura kupinda pamusoro pezvirimwa (kana pamusoro pemasora nezvipembenene), kupwanya ganda rakaita serakisi reganda rezvirimwa, kugonesa zvinhu zvinoshanda kuti zvipinde nekukurumidza, kuvandudza mwero wekushandiswa uye simba rekudzora mishonga yekuuraya zvipembenene, uye panguva imwe chete kuderedza marara anokonzerwa nekudonha kwemushonga wemvura.
5. Mimwe minda yemakemikari yeindasitiri neyamazuva ese
Indasitiri yerabha: Sodium 2-butyl-1-naphthalenesulfonate inoshanda semulsifier mukugadzira rabha dzakapfava (dzakadai serabha yechisikigo nerabha yakagadzirwa latex), ichibatsira kuti zvidimbu zverabha zviparadzirwe zvakaenzana mumvura, zvichiwedzera kugadzikana kwerabha, uye zvichiita kuti kugadziriswa kuitwe (sekuputira nekuumba).
Muminda yemakemikari ezuva nezuva: Butylnaphtalenesulfonic acid sodium salt inoshandiswa zvishoma mu detergent uye cleansing agent formulas kubatsira mukuvandudza kugona kubvisa tsvina. Kana kuti inogona kushandiswa se emulsifier mune zvimwe zvizoro (senge lotions nema creams) kuvandudza kufanana uye kugadzikana kwechimiro chechigadzirwa.
Isu tiri nyanzvi yekugadzira zvinhu zvemakemikari uye tanga tichiita basa rekugadzira zvinhu izvi.munyu we sodium munyu we butylnaphtalenesulfonic acidkwemakore anoda kusvika makumi maviri. Kana muchida chigadzirwa ichi, ndapota taurai nesu chero nguva.
