Tenneries nthawi zambiri imagwirizanitsidwa ndi kununkhira kwa "sulfide" sulfide ", komwe kumachitika chifukwa cha kuchuluka kwa ma sulfphydric mpweya, komwenso kumadziwika kuti hydrogen sulfide. Mitengo yotsika ngati 0,2 ppm ya H2S ili kale yosasangalatsa kwa anthu ndi kuchuluka kwa 20 ppm sikugwirizana. Zotsatira zake, matupi angakakamizidwe kutseka majeremusi kapena okakamizidwanso kuti apezenso malo okhala anthu.
Monga momwe Beardhouse ndi kusindika nthawi zambiri zimachitika m'malo omwewo, fungo limakhala locheperako. Kudzera mwa zolakwa za anthu, izi nthawi zonse zimakhala zowopsa zophatikizika ndi zoyandama zokhala ndi sulfide wokhala ndi mphukira yoyandama ndikumasula H2S. Pa mulingo wa 500 ppm yonse yoletsedwa ndi mpweya wotsekedwa ndipo mpweya, motero, umakhala wosamveka komanso wowonera chifukwa cha anthu 30 mphindi zomwe zikulepheretsa kuledzera. Pa ndende za 5,000 ppm (0,5%), kuopsa kwatchulidwa kuti mpweya umodzi ndi wokwanira kuyambitsa kufa kwa masekondi nthawi yayitali.
Ngakhale panali mavuto onsewa komanso ngozi zonsezi, Sulphide adakonda mankhwala omwe amakonda kwambiri pazaka zopitilira zana. Izi zitha kutchulidwa kuti njira zina zothetsa izi: Kugwiritsa ntchito ma sulphic shulphidedededes awonetsa kuti ndi oyenera koma osavomerezedwa chifukwa cha ndalama zowonjezera zomwe zimakhudzidwa. Osadandaula ndi promolytic ndi Keratolytic Syzyme adayesedwa mobwerezabwereza koma chifukwa chosasankha zinali zovuta kuti uziwongolera. Ntchito yambiri yakhalanso yopanda pake, koma mpaka lero ndizochepa pakugwiritsa ntchito kwake chifukwa chovuta kupeza zotsatira.

Njira Yosamveka

Congeton yawerengetsa kuchuluka kwa sodium sulphium sulphide wa mafakitale (60-70%) Pochita izi, kuchuluka komwe kwagwiritsa ntchito njira yodalirika kumakhala kokwera kwambiri, ndi 2-3%. Cholinga chachikulu chonena izi ndikuti kuchuluka kwa zovuta kumatengera kuchuluka kwa ma aionshide a syphide (s2-). Zoyandama zazifupi nthawi zambiri zimagwiritsidwa ntchito kupeza kuchuluka kwa Sulfupside kwambiri. Komabe kuchepetsa kuchuluka kwa sulphide kumakhudzanso kuchotsedwa kwa tsitsi munthawi yovomerezeka.
Mosamala kwambiri momwe kuchuluka kwa osaganizira kumadalira mankhwala omwe ali ogwiritsidwa ntchito ndi mankhwala ogwiritsa ntchito, ndizodziwikiratu kuti kuchuluka kwambiri ndikofunikira makamaka pakuukira njira inayake. Munthawi yotentha ya tsitsi, mfundo iyi ndi Keratin ya Cortex, yomwe imawonongeka ndi sulphide chifukwa cha kuwonongeka kwa mabatani a cystine.
Munthawi yotetezeka tsitsi, pomwe Keratin imatetezedwa ndi chitetezo cha Katemera, mfundo yake imangochitika makamaka mapuloteni a tsitsi omwe amangokhala ndi michere ya alkalilic, ngati ilipo. Mfundo yachiwiri komanso yofunika kwambiri youkira ndi Pre-Keratin yomwe ili pamwamba pa babu la tsitsi; Itha kuchepetsedwa ndi purteolytic hydrolysis pamodzi ndi KeratolyItic zotsatira za Sulphide.
Njira iliyonse yomwe imagwiritsidwa ntchito povuta, ndiyofunikira kwambiri kuti ziwonetserozo zitheke zimapezeka mosavuta chifukwa cha njira zamankhwala zomwe zimapangitsa kuti zikhale zovuta kwambiri. Izi zikutanthauzanso kuti ngati mwayi wopeza njira yogwira ntchito (mwachitsanzo, laimu, sulzhide, enzyme etc) ku malo ofunikira atha kugwiritsidwa ntchito, ndikotheka kugwiritsa ntchito kwambiri mankhwalawa.

Kuyenda ndi chinthu chofunikira kwambiri kuti musakhale bwino

Mankhwala onse omwe amagwiritsidwa ntchito molakwika ndi ma sungunuka amadzi ndipo madzi ndi njirayi sing'anga. Chifukwa chake mafuta motero chifukwa cha cholepheretsa zachilengedwe kuchepetsa mphamvu iliyonse yosasangalatsa. Kuchotsa mafuta kumatha kusintha magwiridwe antchito osagwira ntchito. Zotsatira zake, maziko a osagwira ntchito molakwika ndi chowonjezera champhamvu cha mankhwala ayenera kuyikika mu gawo.
Cholingacho ndi njira yoyendetsera tsitsi komanso kubisala kwamitundu ndikuchotsa mafuta a sebaceous. Kumbali inayo imayenera kupewa kuchotsa mafuta ambiri ambiri, makamaka kuchokera ku thupi, chifukwa nthawi zambiri sikotheka kuzisunga ndi mafuta. Izi zimabweretsa mawonekedwe amtundu wamafuta m'malo mwa "youma" imodzi, yomwe imapangitsa kugwira ntchito bwino kwa ntchito yopanda pake.
Ngakhale kuchotsa kwa mafuta kuchokera ku zinthu zina zomwe zimapangitsa kuti zikhale za chikopa pambuyo pake zimapangitsa kuti zitsambanetsatane wa mankhwala osasangalatsa, zipolopolo zina zimatha kutetezedwa nthawi yomweyo. Zochitika zimawonetsa kuti kutsika kwambiri ndi mikhalidwe ya anthu padziko lapansi - ma alkali amakangana pamapeto pake kumapangitsa kuti abwerere ndi ziwiya zamitundu ndi mabelumita ambiri. Pakadali pano palibe kufotokozera kokwanira kwa chowonadi ichi, koma manambala owunikira akuwonetsa kuti kuwulutsa kwambiri ndi kufalikira kosiyanasiyana kwa zinthu zomwe zimafanizira ndi phulusa la soda.
Ngakhale kuti kupezeka kwa phulusa ndi phulusa la ku Soda ndi yunifolomu, kugwiritsa ntchito dziko lapansi ma aclines kumapangitsa zinthu zapamwamba m'magawo omasulidwa madera omwe asungidwa, mwachitsanzo. Kaya izi zikuchitika chifukwa chochotsa mafuta kuchokera kumadera ena kapena kubwereza kwa mafuta a mafuta sanganenedwe pakadali pano. Kaya ndi chifukwa chotani, zotsatira zabwino pa zokolola zodula zimasakanika.
Wosanja watsopano wotsika amagwiritsa ntchito zotsatira zake; Imaperekanso malo oyenera a mizu yabwino tsitsi ndi kuchepetsedwa kwa tsitsi ndi kuchepetsedwa kwa Sulfide kupatsidwa, ndipo nthawi yomweyo imasunga umphumphu wa mabelu ndi ma flanks.

Mafuta otsika a sulphide adathandizira osagwira ntchito

Chikopa chikakonzedwa moyenera kuwuluka, chosasangalatsa chimakwaniritsidwa bwino ndi njira yogwiritsira ntchito przymatic protengoly protecit ndi protoretic of Sulphide. Komabe, munthawi yotetezeka tsitsi, ndalama zoperekera kwa sulphide tsopano zitha kuchepetsedwa kwambiri kuti zikhale zongoyerekeza 1% yokhayo kuti ibiseni kubisala. Izi zitha kuchitika popanda kunyengerera ponena za kuchuluka kwa momwe osavomerezeka kapena ukhondo wambiri. Kupereka kotsika kumabweretsanso kuchuluka kwa Sulphide komwe kumatsika kwambiri ndikubisala komanso kubisala (kumasuthira zocheperako Ngakhale kutentha kwa tsitsi kumatha kuchitidwa pazomwezo.
Kupatula pazeolytic zotsatira za sulphide, pulolyc hydrolysis nthawi zonse imafunikira kuti musangalale. Bulu latsitsi, lomwe limakhala ndi mapuloteni, ndipo pre-rea-keratin yomwe ili pamwamba pake imafunikira kuukiridwa. Izi zimatheka ndi achi Alkalinity ndipo mwanjira zina ndi ma promolytic michere.
Collagen imakonda kwambiri hydrolysis kuposa Keratin, ndipo pambuyo pa laimu kuwonjezera decogen ndikusinthidwa moyenera. Kuphatikiza apo, kutupa kwa alkaliline kumapangitsanso kuti ziwonongeke. Chifukwa chake, ndi zotetezeka kwambiri kuti mukwaniritse kumenyedwa kwa babu ndi pre-rearatin pa pH yotsika isanachitike mandimu.
Izi zitha kuchitika ndi protengoly enzymation yopanda tanthauzo yomwe ili ndi ntchito yayikulu kwambiri mozungulira pH 10.5. Pa PH yofananira ndi miyendo yokhoma pafupifupi 13, ntchitoyi ndi yotsika kwambiri. Izi zikutanthauza kuti zopepuka sizikudziwika kuti zimawonongeka ndi hydrolytic ikakhala m'malo mwake.

Kuchepa kwa Sulphide, njira yotsika tsitsi

Wokhazikika woteteza madera omwe amatayidwa ndi chikopa chopanda chikopa chomwe chimapangitsa kuti pH yotsimikizika ikhale yotsimikizika bwino kwambiri komanso yabwinobwino kwambiri. Nthawi yomweyo, kachitidwe katsopano katsopano kamapangitsa kuti atulutsidwe a Sulhide, ngakhale atatentha tsitsi. Koma mapindu apamwamba kwambiri amapezeka ngati amagwiritsidwa ntchito ngati tsitsi lotetezeka. Zotsatira zophatikizika zowoneka bwino komanso zosankha za promolythc ya enzyme ya enzyme yodalirika popanda zovuta popanda mavuto a tsitsi labwino komanso mizu ya tsitsi komanso ukhondo wabwino kwambiri.

Dongosolo limasintha chinsinsi chotsegulira chomwe chimatsogolera ku chikopa chofewa ngati sichikulipitsidwa ndi kuchepetsa kwa laimu. Izi, kuphatikiza ndi kuwunika tsitsi ndi fyuluta, kumabweretsa kuchepetsedwa kwakukulu.

Mapeto

Njira yotsika ya sulfide, yotsika ya laimu yokhala ndi epidermis yabwino, mizu ya tsitsi ndi tsitsi ndiyotheka pokonza chikopa choyenera. Njira yosankha Enzymatic Exilory ikhoza kugwiritsidwa ntchito popanda kukhulupirika kwa tirigu, mabelu ndi ma flanks.
Kuphatikiza zinthu zonse ziwiri, ukadaulo umapereka maubwino otsatirawa panjira yogwira ntchito:

- chitetezo chabwino
- fungo lopanda tanthauzo
- kuchepetsedwa kwambiri pamalo - Sulphide, nayitrogeni, cod, sludge
- Kukhazikika komanso kosasunthika kuyika, kudula ndi chikopa chabwino
- kutsitsa mankhwala, njira ndi mtengo wowononga
