Mokhoa oa ho kopanya oanaphthalene sesebelisoa se fokotsang metsi se sebetsang hantle haholo:

(1).Naphthalene e ne e le sulfonated ka mocheso o phahameng (160 ~ 165 ℃), haholo-holo e hlahisa β-naphthalene sulfonic acid, empa hape le palo e nyenyane ea naphthalene sulfonic acid;

(2). Eketsa metsi ho etsa α-naphthalene sulfonic acid hydrolyze off, etsa hore β-naphthalene sulfonic acid content e eketsehe;

(3). β-naphthalene sulfonic acid le formaldehyde condensation;

(4) Ho se nke lehlakore.

Theknoloji ea kopo eanaphthalene e sebetsa hantle haholo ho fokotsa metsi:

1.Matla a pele le konkreite e matla e phahameng e lokiselitsoe. Ha o kopanya 0.5% ~ 1%naphthalene sesebelisoa se fokotsang metsi se sebetsang hantle haholoho ea ka boima ba samente, metsi a ka fokotsoa ka 16% ~ 25%, 'me matla a konkreite a tšoanang a ka eketsoa ka 20% ~ 50% (matla a pele a konkreite a eketseha ka ho feta).
2.Ho lokisetsa konkreite e kholo ea phallo, ha honaphthalene e sebetsa hantle haholo ho fokotsa metsibakeng sa tekanyo ea samente ea 0.2% ~ 0.5%, matla a konkreite a lula a sa fetohe, a ka eketsa ho theoha ha konkreite ho 10 ~ 25cm, e sebelisetsoang ho bokella matla a khoheli, ho pompa konkreite, ho ka potlakisa tsoelo-pele ea kaho, ho ntlafatsa boleng ba kaho.
3.ave samente, tlas'a boemo ba ho boloka matla a konkreite ha e fokotsehe, ho phaella ka 0.5%naphthalene ntho e sebetsang hantle ya ho fokotsa metsie ka boloka samente hoo e ka bang 20%.
