NgoFebruwari 14, iholide yothando kunye nothando
Ukuba iimveliso zemichiza zineempawu zobudlelwane, ngoko ke imveliso endiza kubelana nawe ngayo namhlanje kusenokwenzeka ukuba ibe 'ngumfo omnandi' odumileyo.
Ukwenziwa kwesikhumba kufuna inkxaso eqinileyo ye-tanning agents, i-lubrication of fatliquors kunye nemibala enemibala yeedayi;ifuna kwakhona uncedo olubanzi lweemveliso ezisebenzayo ezakhiwe ngenjongo yokufezekisa isimbo esifunwayo kunye nokusebenza.
Enye yezinto ezifunekayo ukuqinisekisa ukuba imveliso inokuncediswa ngokugqibeleleyo kwinkqubo yokutshisa kukuba i-blue-blue ifakwe kwi-pH efanelekileyo kunye namathuba okungena afanelekileyo.
Inkqubo ye-neutralization yinyathelo elibalulekileyo ekulungiseleleni zonke ezi mveliso ukuba zingene ngokulinganayo kwaye zinzulu kwisikhumba.
Iinkqubo ezahlukeneyo kwinkqubo yokutshisa zifuna ugxininiso oluhlukeneyo, kwaye ngenxa yokungathathi hlangothi, iipropati ezithambileyo zokukhusela kunye nesenzo esinzulu esisisigxina sibaluleke kakhulu.
Emva kophando olunzulu kunye nophuhliso liqela leTexel, kuye kwasungulwa imveliso entsha:
ukusebenza okuphezulu kwe-cushioning kuthoba i-tannin DESOATEN NSK
Iipropathi ezigqwesileyo zokuthoba kunye nokungena
Ukuphuculwa kokungena kwezinto zekhemikhali
Fumana ufele oluphangaleleyo nolugqityiweyo
Ukuze i-pH isondele kwindawo ye-isoelectric ye-blue-blue kunye nokuqinisekisa ukungena okwaneleyo kwazo zonke izinto ze-anionic, i-pH idinga ukulungiswa kuluhlu lwe-4.5 ukuya kwi-6.5 usebenzisa izinto ze-alkaline ngexesha lenkqubo yokungathathi hlangothi.
Nangona kunjalo, ukuguquguquka okunobundlobongela kwi-pH kubi kakhulu kwinkqubo yolusu kwaye ukungenwa kakubi kwealkalis ezomeleleyo kudla ngokubangela ukungalingani kwe-pH kumphezulu osikiweyo wesikhumba, okukhokelela ekwakhiweni okugqithisileyo kwemathiriyeli yeekhemikhali kumphezulu weenkozo. , engenakungena ngokulinganayo.
Ngelixa isigqibo sibonisa
ukusebenza komgangatho ophezulu wokunciphisa iitannins DESOATEN NSK.
Iimpawu zayo ezibalaseleyo zokuthintela ziqinisekisa utshintsho oluzolileyo noluthambileyo lwe-pH yomanzi-oluhlaza okwesibhakabhaka, ukhozo olusicaba nolucolekileyo, ukudaya ngokulinganayo kunye nokungaguquguquki okufanayo phakathi kwesikhumba.
Iimpawu zayo eziphazamisayo zikwanceda ukungena ngokupheleleyo kunye ne-homogeneity ye-cross-section emanzi-blue, iqinisekisa ukusebenza kokudaya ngentliziyo yesikhumba, ukungena ngokupheleleyo kwe-tanning kunye ne-fatliquoring agents, ukolula kwesikhumba kunye nesivuno esingcono sesikhumba.
Uthando lufana nempepho efudumeleyo yomngcunube engabupholisiyo ubuso bakho
Uthando lufana nobushushu bokwangiwa kwesithandwa
Uthando luthambile kwaye luthe cwaka
Ukusebenza okuphezulu kwe-cushioning ukuthoba i-tannin DESOATEN NSK
Njengomntu "othambileyo kwaye oqinileyo" omnandi othomalalisa ixabiso le-pH "lokungxamiseka".Ngolu suku lukhethekileyo, ikhemistri nayo yayisenziwa ngothando.
