Ma defoamers mu Mafakitale Ogwiritsira Ntchito

Zonyozandizofunikira kwambiri pa ntchito zamafakitale. Njira zambiri zamafakitale zimapanga thovu, kaya ndi kugwedezeka kwa makina kapena kuchitapo kanthu kwa mankhwala. Ngati silikulamulidwa ndi kuchiritsidwa, lingayambitse mavuto akulu.

Thovu limapangidwa chifukwa cha kukhalapo kwa mankhwala ophera tizilombo toyambitsa matenda m'madzi, zomwe zimapangitsa kuti thovu likhazikike, zomwe zimapangitsa kuti thovu lipangidwe. Ntchito ya ophera tizilombo toyambitsa matenda ndikusintha mankhwala ophera tizilombo toyambitsa matenda, zomwe zimapangitsa kuti thovu liphulike ndikuchepetsa thovu.

Kodi mitundu ikuluikulu ya thovu ndi iti?

Foam ya biofoam ndi surfactant:

Biofoam imapangidwa ndi tizilombo toyambitsa matenda pamene timagaya ndi kuwononga zinthu zachilengedwe m'madzi otayira. Biofoam imakhala ndi thovu laling'ono kwambiri lozungulira, lokhazikika kwambiri, ndipo limawoneka louma.

Thovu la surfactant limayamba chifukwa cha kuwonjezera zinthu zosungunulira monga sopo ndi sopo, kapena chifukwa cha zinthu zowononga zomwe zimachitika ndi mafuta kapena mafuta ndi mankhwala ena.

Kodi ma defoamers amagwira ntchito bwanji?

Ma defoamers amaletsa thovu kupanga mwa kusintha mawonekedwe a madzi. Ma defoamers amalowa m'malo mwa mamolekyu a surfactant mu thovu lochepa, zomwe zikutanthauza kuti monolayer si yotanuka kwambiri ndipo nthawi zambiri imatha kusweka.

Kodi mungasankhe bwanji defoamer?

Ma defoamer nthawi zambiri amagawidwa m'magulu awiri: ma defoamer okhala ndi silicone ndi ma defoamer osagwiritsa ntchito silicone. Kusankha kwa defoamer kumadalira zofunikira ndi mikhalidwe ya ntchito yeniyeniyo. Ma defoamer okhala ndi silicone amagwira ntchito bwino pansi pa pH yosiyana ndi kutentha ndipo nthawi zambiri amakondedwa chifukwa cha kukhazikika kwawo komanso kugwira ntchito bwino. Ma defoamer osagwiritsa ntchito silicone ndi ma defoamer opangidwa makamaka ndi zinthu zachilengedwe monga mafuta a amide, sopo wachitsulo, mafuta ochulukirapo, ndi ma esters amafuta acid. Ubwino wa machitidwe osakhala a silicone ndi ma coefficients akuluakulu ofalikira komanso kuthekera kwamphamvu kosweka thovu; vuto lalikulu ndilakuti mphamvu yoletsa thovu ndi yofooka pang'ono chifukwa cha kupsinjika kwakukulu pamwamba kuposa silicone.

Posankha chotsukira mpweya choyenera, zinthu monga mtundu wa makina, momwe ntchito ikuyendera (kutentha, pH, kuthamanga), kugwirizana kwa mankhwala, ndi zofunikira pa malamulo ziyenera kuganiziridwa. Posankha chotsukira mpweya choyenera, makampaniwa amatha kuthana bwino ndi mavuto okhudzana ndi thovu ndikuwongolera magwiridwe antchito onse.

Kodi ndi liti pamene chinthu chowonjezera cha defoaming chikufunika pochiza madzi?

Pa nthawi yothira madzi, nthawi zambiri pamakhala zinthu zomwe zimapangitsa kuti thovu lituluke, monga kugwedezeka kwa madzi, kutulutsa mpweya wosungunuka, komanso kupezeka kwa sopo ndi mankhwala ena.

Mu njira zoyeretsera madzi akuda, thovu limatha kutsekereza zipangizo, kuchepetsa kugwira ntchito bwino kwa njira yoyeretsera, komanso kusokoneza ubwino wa madzi oyeretsera. Kuwonjezera zinthu zoyeretsera madzi m'madzi kungachepetse kapena kuletsa kupangika kwa thovu, zomwe zimathandiza kuti njira yoyeretsera igwire bwino ntchito komanso kukonza ubwino wa madzi oyeretsera.

Mankhwala ochotsera thovu kapena mankhwala oletsa thovu ndi mankhwala omwe amawongolera, ngati kuli kofunikira, kuchotsa thovu m'madzi okonzedwa kuti apewe zotsatira zoyipa za thovu pamlingo wosafunikira kapena wopitirira muyeso.

Zotsukira tsitsi zathu zitha kugwiritsidwa ntchito m'magawo otsatirawa:

● Makampani opanga zamkati ndi mapepala

● Kuyeretsa madzi

● Makampani opanga sopo

● Makampani opanga utoto ndi zokutira

● Makampani opanga mafuta

● Ndi mafakitale ena
