Iindaba

I-tanneries ihlala inxulunyaniswa nenqanaba le-Sulfide kunye ne-Obnoxide ", eneneni ebangelwa kukuxinanisa okuphantsi kwegesi ye-SulfyDDric, ekwabizwa ngokuba yi-hydrogen sulfide. Amanqanaba asezantsi njenge-0.2 i-PPM yee-H2S sele ingathandekiyo ebantwini kunye nokuxinana kwe-20 ye-PPM ayinyamezeleki. Ngenxa yoko, i-tanneries inokunyanzelwa ukuba ivale imisebenzi yegumbi okanye inyanzeliswa ukuba iphinde iphinde ifumaneke kwiindawo ezinabantu abaninzi.
Njengoko igumbi lokuhlala lihlala lenziwa kwindawo enye, ivumba leyingxaki engaphantsi. Ngeempazamo zabantu, oku kuhlala kwenza ingozi yokuxuba i-acidic dats kunye ne-sulfide equkethe igumbi lokudakumba kunye nokukhupha izixa eziphezulu ze-H2S. Kwinqanaba le-PPM yonke i-ppm yonke i-ovictory ivinjelwe kwaye irhasi, ngenxa yoko, iya kuba kungabinamsebenzi kunye nokuvezwa kwemizuzu engama-30 kwimiphumo yobomi. Kwi-propm ye-5,000 ye-PPM (i-0.5%), ityhefu ivakaliswa kukuba ukuphefumla okungaphezulu kwanele ukubangela ukufa kwangoko kwimizuzwana.
Ngaphandle kwazo zonke ezi ngxaki kunye neengozi, i-sulphhide yikhemikhamikhali ekhethiweyo yokungathandanga ngaphezulu kwenkulungwane. Oku kunokubangelwa ziindlela ezizezinye ezingafumanekiyo: Ukusetyenziswa kwe-Sulfisic Sulfisic kubonakalisiwe ukuba kunokwenzeka kodwa akuvunywanga ngenxa yeendleko ezongezelelweyo ezichaphazelekayo. Ukungathandani kuphela yiProteolytic kunye ne-keratolytic enmememe iphinde yakhiwe kwakhona kodwa ngokusilela kokukhetha kwakunzima ukuziqhelanisa nokulawula. Umsebenzi omninzi sele utyalomali ekungadibaniyo kwi-oxidage, kodwa kude kube namhlanje ilinganiselwe kusetyenziso lwayo njengoko kunzima ukufumana iziphumo ezingaguqukiyo.

Inkqubo engathandekiyo

UCovington ubale inani le-theodium ye-sodium sulphide yebanga lezorhwebo (60-70%) yenkqubo yokutsha yeenwele ibe yi-0.6%, isalamane sokufihla ubunzima. Xa uziqhelanisa, iimali eziqhelekileyo eziqeshiweyo zenkqubo ethembekileyo ziphezulu kakhulu, ezizezi-2-3%. Esona sizathu seli yinto yokuba inqanaba lokungathandanga lixhomekeke kuxinzelelo lwe-sulphide ion (S2-) kwi-float. Iidada ezimfutshane zihlala zisetyenziselwa ukufumana uxinzelelo oluphezulu lwe-sulphide. Nangona kunjalo ukunciphisa amanqanaba e-sulphphide kuchaphazela kakubi ukususwa kweenwele ezigqityiweyo ngexesha elifanelekileyo.
Ukujonga ngokusondeleyo malunga nendlela inqanaba lokungabinamali kuxhomekeke kwindlela yokuxinana kweekhemikhali eziqeshiweyo, kuyacaca ukuba uxinzelelo oluphezulu lufuneka ngokukhethekileyo kwinqanaba lokuhlaselwa kwinkqubo ethile. Kwinkqubo etshisayo yeenwele, le ngongoma yokuhlaselwa yi-keratin ye-cortex ye-cortex, ekhutshiwe yi-sulphide ngenxa yokuqhekeka kweebhulorho zeCystic.
Kwinkqubo yenkcitho yeenwele, apho i-keratin ikhuselwe linyathelo lokugonya, inqaku lokuhlaselwa ikakhulu i-protein ye-probrolylid i-hydrolymed kuphela okanye nge-enzymes yeproteolytic, ukuba ikhona. Inqaku lesibini nelibaluleke kakhulu lokuhlasela yiKeratin yangaphambi kwe-quratin ephakathi kwebhalbhu yehabhu; Ingancitshiswa yi-proteolytic hydrolysis edityaniswe nesiphumo se-suratolytic.
Nokuba yeyiphi na inkqubo esetyenziselwa ukungathandanga, kubaluleke kakhulu ukuba ezi ngxelo zohlaselo zifikeleleka ngokulula kwiichemicals, zivumela uxinzelelo lwendawo ephezulu ye-sulphide eliza kubangela ukungalingani. Oku kuthetha ukuba ukuba ukufikelela ngokulula kweekhemikhali zenkqubo yekhemikhali (umz. I-Lime, i-sulphhide, i-enzyme njlnjl njl. Ewe kunjalo ekusebenziseni izixa ezisezantsi kwezi khemikhali.

Ukuntywila kuyinto ephambili ekungasebenzi kakuhle

Zonke iikhemikhali eziqashwe kwinkqubo engathandekiyo kukunyibilika kwamanzi kwaye amanzi yinkqubo. Igrisi ke ngoko isithintelo semvelo sinciphisa ukusebenza kwalo nawuphi na imichiza engabhaliswanga. Ukususwa kwegrisi kunokuphucula kakhulu ukusebenza kwenkqubo yokungabinamdla. Ngenxa yoko, isiseko sokungazifumani ngempumelelo ngokuncitshiswa kwekhemikhali
Ithagethi yindawo efanelekileyo yokudinwa kweenwele kunye nomphezulu wokufihla kunye nokususwa kwegrisi ye-sebaceous. Kwelinye icala kufuneka sikuphephe ukususa igrisi eninzi kakhulu, ngakumbi enyameni, kuba ihlala ingakwazi ukuyigcina kwi-emulsion kunye namafutha amdaka aya kuba sisiphumo. Oku kukhokelela kumphezulu wegrisi kunokuba umntu owomileyo "owomileyo", owawuchaphazela ukusebenza ngempumelelo kwenkqubo engathandekiyo.
Ngelixa ukufuduka okukhethiweyo kwegrisi kwizinto ezithile zolwakhiwo zabafihla zibahlasela kuhlaselo olulandelayo lweekhemikhali ezingathandekiyo, ezinye iindawo zesifihla zinokukhuselwa kuyo. Amava abonisa ukuba i-SOKIRS IIMPAWU ZOKUGQIBELA EZIQHELEKILEYO NGEXESHA LOKUGQIBELA LWEZOBUCHULE NGEXESHA LOKUFUNDA NOKUZIPHATHA. Ukuza kuthi ga ngoku akukho nkcazo ibaluleke ngokupheleleyo yeli nyani iqinisekileyo, kodwa amanani oluhlalutyo abonisa ukuba i-Alkalines ye-Alkalines iphuzile i-SHICY NOKUQHUTYELWA NOKUTHENGA NOKUTHENGELWA NOKUTHENGELWA NOKUTHENGELWA NOKUTHENGELWA NOKUTHENGELWA NOKUTHENGELWA NOKUTHENGELWA NOKUTHENGELWA NOKUTHENGELWA NOKUTHENGELWA NOKUTHENGELWA NOKUTHENGELWA NOKUTHENGELWA NOKUTHENGELWA NOKUTHENGELWA NOKUTHENGELWA NOKUTHENGELWA NOKUTHENGELWA NOKUTHENGELWA NOKUTHENGELWA NOKUTHENGELWA NOKUTHENGELWA NOKUTHENGELWA NOKUTHENGELWA NOKUTHENGELWA NOKUTHENGELWA NOKUTHENGELWA NOKUTHENGA NOKUTHENGA NOKUTHENGA I-SODA.
Ngelixa ifuthe le-ishreyitha leSoda likhulu iyunifomu, ukusebenzisa umhlaba i-Alkalines kuphumela kumxholo ophezulu wezinto ezinamafutha kwiindawo ezikhoyo zepelt, okt kwiiflethi. Nokuba ngaba oku kungenxa yokukhutshelwa kwamafutha kwamanqatha ukusuka kwamanye amalungu okanye ukunikezelwa kwakhona kwezinto ezinamafutha akunakuthethwa ngalo mzuzu. Nokuba yeyiphi na isizathu esiyinyani, ifuthe eliyingenelo kwisivuno esisikiweyo alinakuphikiswa.
Iarhente entsha yokhetho olukhethiweyo isebenzisa iziphumo ezichaziweyo; Ibonelela ngeemeko zangaphambi kweenwele ezilungileyo kunye nokususwa kweenwele ezilungileyo kunye nokuncitshiswa kweenwele ezinciphileyo, kwaye kwangaxeshanye kuyayigcina ingqibelelo yeentsimbi kunye neeflethi.

I-sulzfide ephantsi i-enzyfide encedisileyo

Emva kokuba isifiselo kulungiselelwe ngokufanelekileyo ukuthoba, ukungathandanga kufezekiswe ngokufanelekileyo ngenkqubo esebenzisa indibaniselwano yokuqulunqa iproteolytic yokuqulunqa iprojekyuli kunye nefuthe le-keratolylic le-sulphide. Nangona kunjalo, kwinkqubo yenkazana ekhuselekileyo, ukubonelelwa kwe-sulhide ngoku kungancitshiswa kakhulu kwinqanaba le-1% kuphela yesihlobo sokufihla ubunzima kwi-Bideger kwi-Bideger kwi-Bideger kwi-Bideger ye-Bigger ye-Bigger ye-Bigger ye-Bigger Bovine. Oku kunokwenziwa ngaphandle kokulalanisa malunga nenqanaba kunye nokusebenza kwempumelelo yokungathandanga okanye ukucoceka kwe-pelt. Isibonelelo esisezantsi sikhokelela kumanqanaba ancitshisiweyo se-sulphide kwi-ping kunye ne-figh (iya kukhutshwa kancinci i-H2S emva kwexesha elizayo.). Nditsho nenkqubo yokutsha yeenwele zemveli inokwenziwa kwisibonelelo se-sulphide esisezantsi.
Ngaphandle kwesiphumo se-biratolytic ye-sulphide, i-proteolytic hydrolysis ihlala ifuneka ngokungathandangayo. I-bulb yeenwele, equka iprotein, kunye neKeratin engaphambi kwayo, kufuneka ihlaselwe. Oku kuphunyezwa ngu-Alkalinity kwaye ngokuthe chu nangee-enzymes zeproteolytic.
I-collagen ixhotywe kakhulu kwi-hydrolysis kune-ketin, kwaye emva kokuba i-LIME ukongeza i-comy ye-compleges iguqulwe ngemichiza kwaye ngenxa yoko inobuthathaka ngakumbi. Ukongeza, ukudumba kwe-alkaline kukwenza i-pelt ifakelwe kwimonakalo yomzimba. Kungoko, ke, kukhuseleke kakhulu ukufezekisa uhlaselo lweproteolytic kwi-bulb ye-bulb kunye ne-pre-ketin kwi-thetin esezantsi kwe-PH ngaphambi kongezwa kwekalika.
Oku kungaphunyezwa ngokufumana i-prozytic entsha yeprothenolytic yokuqhelisela okungathandangayo enomsebenzi ophezulu we-PH 10.5. Kwi-PH yenkqubo yenkqubo yokuphela kwe-13, umsebenzi usemgangathweni. Oku kuthetha ukuba i-pelt ayichaphazeli i-hydrodiction ye-hydrolytic xa ikwimeko yayo enobuthathaka.

I-sulphide esezantsi, i-lime ye-lime ye-lime ye-Lime

Iarhente yokunyuka ikhusela kwiindawo ezihlelweyo zokuzifihla kunye nokungafuneki okungafunekiyo okuphezulu kwi-EPE PH, iimeko ze-PH ezifanelekileyo ukufumana umgangatho owona mgangatho kunye nobuninzi bendawo yesikhumba. Kwangelo xesha, inkqubo entsha engathandekiyo ivumela ukuncitshiswa kwe-sulphide, nakwinkqubo yokutsha kweenwele. Kodwa ezona zibonelelo ziphezulu zifunyanwa ukuba isetyenziswa kwinkqubo yenkcitho yeenwele. Iziphumo ezidityanisiweyo zendlela efanelekileyo yokuqhutywa kunye neproteolytic yokuqulunqa okhethekileyo ze-enzyme zikhokelela ekungazipheni kakhulu ngaphandle kweenwele kunye neengcambu zeenwele kunye nokucoceka kweenwele kunye nokucoceka okuphuculweyo kwepelt.

Le nkqubo iphucula ukuvulwa kwesifihlo esikhokelela kwisikhumba esithambileyo ukuba asibubuyekeli ngokuncitshiswa kwe-Lime. Oku, ngokudibeneyo nokuhlolwa kweenwele ngecebo lokucoca, kukhokelela ekunciphiseni kwe-slulual.

Ukuqukumbela

I-sulfide ephantsi, inkqubo ye-lime ephantsi ene-epidermis elungileyo, ingcambu yeenwele kunye nokususwa kweenwele ezilungileyo kunokwenzeka ngokulungiswa ngendlela efanelekileyo yokufihla. Isincedisi-munzymatic ofundela esinokukhetha sinokusetyenziswa ngokungathandanganga ngaphandle kokunyaniseka senkozo yengqolowa, iintsimbi kunye neeflethi.
