Ntchito Zisanu Zazikulu za Opanga Ma Surfactants

1.Zotsatira Zokometsera

Kugwirizana kwathunthu kwa magulu a hydrophilic ndi lipophilic m'mamolekyu a surfactant pa mafuta kapena madzi. Kutengera ndi zomwe zachitika, kuchuluka kwa Hydrophilic-Lipophilic Balance (HLB) kwa ma surfactants kumakhala kochepa pa 0-40, pomwe kwa ma non-ionic surfactants kumakhala mkati mwa 0-20.

Kusakaniza njira yowonjezera:HLB=（HLBa Wa+HLBb /Wb） / （Wa+Wb）Kuwerengera kwa Chiphunzitso：HLB=∑（Mtengo wa HLB wa Magulu Okonda Madzi）+∑（Mtengo wa HLB wa Magulu Okonda Mafuta）-7 HLB：3-8 W/O-type Emulsifier：Pakati；Mtengo wa HLB wa Sopo Wokonda Madzi：8-16 O/W-type Emulsifier：Span；Divalent Sopo.

Dongosolo logawanitsa madzi lopangidwa mwa kufalitsa madzi amodzi kapena angapo ngati madontho amadzimadzi okhala ndi mainchesi opitilira 10−7m mumadzi ena osasakanikirana limatchedwa emulsion. Emulsifier iyenera kuwonjezeredwa kuti ikhalebe yokhazikika. Kutengera kapangidwe ka emulsifier, imatha kupanga emulsion yamafuta-mu-madzi (O/W) yokhala ndi madzi ngati gawo lopitilira kapena emulsion yamadzi-mu-mafuta (W/O) yokhala ndi mafuta ngati gawo lopitilira. Nthawi zina, mtundu wina wa surfactant umafunika kuwonjezeredwa kuti uswe emulsion, yomwe imatchedwa demulsifier. Imalekanitsa gawo logawanitsidwa ndi malo ogawanitsira mu emulsion. Mwachitsanzo, ma demulsifier amawonjezeredwa ku mafuta osakonzedwa kuti alekanitse mafuta ndi madzi.

2. Zotsatira za thovu ndi kuyeretsa

Mankhwala opangidwa ndi ma surfactants amagwiritsidwanso ntchito kwambiri mumakampani opanga mankhwala. Popanga mankhwala, mankhwala ambiri osasungunuka m'madzi monga mafuta ena ofooka, ma cellulose osungunuka m'mafuta ndi mahomoni a steroid amatha kupanga mayankho owonekera ndikuwonjezera kuchuluka kwawo chifukwa cha mphamvu ya ma surfactants yosungunuka. Pokonzekera mankhwala, ma surfactants amagwira ntchito ngati ma emulsifiers ofunikira, othandizira kunyowetsa, othandizira opachika, othandizira thovu ndi othandizira kuyeretsa. "Thovu" limatanthauzidwa ngati mpweya wotsekedwa ndi filimu yamadzi. Ma surfactants ena amatha kupanga mafilimu amphamvu inayake akasakanikirana ndi madzi, omwe amasunga mpweya kuti apange thovu; ma surfactants otere amatchedwa othandizira kuyeretsa thovu ndipo amagwiritsidwa ntchito poyatsira thovu, kuzimitsa moto wa thovu ndikuyeretsa & kuchotsa banga. M'malo mwake, ma defoamers amafunikanso nthawi zina: mwachitsanzo, thovu lochulukirapo limapangidwa panthawi yopanga shuga ndi kukonza mankhwala achi China, kotero ma surfactants oyenera ayenera kuwonjezeredwa kuti achepetse mphamvu ya filimu yamadzi, kuchotsa thovu ndikuletsa ngozi.

3. Kuyimitsa mphamvu

Mu makampani opanga mankhwala ophera tizilombo,Pamafunika kuchuluka kwa ma surfactants pa ufa wonyowa, zinthu zosungunuka, ndi ma emulsions osungunuka. Mwachitsanzo, zosakaniza zogwira ntchito mu ufa wonyowa nthawi zambiri zimakhala zinthu zachilengedwe zomwe zimakhala ndi hydrophobicity. Pokhapokha ngati pali ma surfactants, omwe amachepetsa mphamvu ya madzi pamwamba, tinthu ta mankhwala ophera tizilombo timanyowa ndi madzi ndikupanga madzi osungunuka.

Kugwiritsa ntchito ma surfactants pakuyandama kwa miyala kumadalira mphamvu yothandizira kuyandama. Madontho a miyala amasunthidwa pamene mpweya ukuwombedwa kuchokera pansi pa thanki; thovu lonyamula tinthu tating'onoting'ono ta miyala limasonkhana pamwamba. Thovu limeneli limasonkhanitsidwa, ndipo thovu limasweka ndikusungunuka kuti likwaniritse cholinga chowonjezera miyala. Dothi lopanda miyala ndi miyala zimakhala pansi pa thanki ndipo zimachotsedwa nthawi zonse. Pamene 5% ya pamwamba pa tinthu ta miyala yamtengo wapatali yaphimbidwa ndi osonkhanitsa, pamwamba pake pamakhala popanda madzi, zomwe zimapangitsa kuti tinthu ta miyala yamtengo wapatali tigwirizane ndi thovulo ndikuyandama pamwamba pa madzi kuti zisonkhanitsidwe mosavuta. Osonkhanitsa oyenera ayenera kusankhidwa kotero kuti magulu awo okonda madzi amamatiridwa pamwamba pa tinthu ta miyala yamtengo wapatali, ndi magulu okonda madzi akuyang'ana madzi.

4. Kupha tizilombo toyambitsa matenda ndi kuyeretsa thupi

Mu makampani opanga mankhwala, angagwiritsidwe ntchito ngati mankhwala ophera tizilombo toyambitsa matenda komanso ophera tizilombo toyambitsa matenda. Zotsatira zake zopha tizilombo toyambitsa matenda komanso zophera tizilombo toyambitsa matenda zimachitika chifukwa cha kugwirizana kwawo kwakukulu ndi mapuloteni omwe ali mu biofilms ya mabakiteriya, zomwe zimawononga kapena kuletsa mapuloteniwa. Mankhwala ophera tizilombo toyambitsa matenda awa amakhala ndi kusungunuka kwakukulu m'madzi. Kutengera kuchuluka kwa mankhwala omwe amagwiritsidwa ntchito, angagwiritsidwe ntchito pophera tizilombo toyambitsa matenda pakhungu lisanachitidwe opaleshoni, pophera tizilombo toyambitsa matenda pabala kapena mucous membrane, pophera tizilombo toyambitsa matenda pazida, komanso pophera tizilombo toyambitsa matenda m'malo ozungulira.

5. Chotsukira ndi kuyeretsa zotsatira

Kuchotsa dothi lamafuta ndi njira yovuta kwambiri, yomwe imagwirizana ndi ntchito zomwe zatchulidwa pamwambapa monga kunyowetsa ndi kutulutsa thovu. Ma detergent nthawi zambiri amafunika kuwonjezera zosakaniza zosiyanasiyana kuti awonjezere mphamvu yonyowetsa pa zinthu zomwe zikuyeretsedwa, komanso ali ndi ntchito monga kupatsa thovu, kuyeretsa, ndi kulowa pamalo oyeretsedwa kuti apewe kuipitsidwanso. Pakati pawo, njira yochotsera kuipitsidwa kwa ma surfactants, omwe ndi zigawo zazikulu, ndi motere: madzi amakhala ndi mphamvu yayikulu pamwamba komanso ntchito yonyowetsa pang'ono pa mabala a mafuta, zomwe zimapangitsa kuti zikhale zovuta kutsuka mabala a mafuta. Pambuyo powonjezera ma surfactants, magulu a hydrophobic amayang'ana pamwamba pa nsalu ndikumata dothi, zomwe zimapangitsa kuti dothi lichoke pang'onopang'ono pamwamba. Dothi limayikidwa m'madzi kapena limayandama pamwamba ndi thovu kenako nkuchotsedwa, ndipo pamwamba poyera pamakhala mamolekyu a surfactant. Pomaliza, ziyenera kudziwika kuti ntchito ya ma surfactants si chifukwa cha gawo limodzi lokha la ntchito yawo; nthawi zambiri, ndi zotsatira za kuphatikizana kwa zinthu zingapo. Mwachitsanzo, mumakampani opanga mapepala, angagwiritsidwe ntchito ngati zophikira, zochotsera mapepala otayidwa, zoyezera kukula, zoletsa utomoni, zochotsera mafoam, zofewetsa, zoletsa kutentha, zoletsa masikelo, zofewetsa, zochotsera mafuta, zophera tizilombo toyambitsa matenda ndi algaecides, zoletsa dzimbiri, ndi zina zotero.
