I-Debut ethi "Sweet guy" |Izincomo ze-Decision Premium-Ukungathathi hlangothi kwama-tannins anezakhiwo eziphakeme zokugoba DESOATEN NSK
14 February, iholidi lothando nezothando
Uma imikhiqizo yamakhemikhali inobudlelwano bezakhiwo, khona-ke umkhiqizo engizokwabelana nawe namuhla kungenzeka kube 'umfana omnandi' odumile.
Ukwakhiwa kwesikhumba kudinga ukusekelwa okuqinile kwama-ejenti okushuka, ukugcotshwa kwama-fatliquors kanye nemibala enemibala yodayi;idinga nosizo lwemikhiqizo eminingi yokusebenza eyakhelwe inhloso ukuze kuzuzwe isitayela nokusebenza okufunayo.

Yonke indlela eya emhlabeni 'we-formaldehyde-free' |Isincomo semikhiqizo yochungechunge lwe-amino resin yesinqumo
Umthelela obangelwa i-formaldehyde yamahhala ekhiqizwa ngesikhathi sokushukwa kwesikhumba kuye kwashiwo ngabakwa- tanneries kanye namakhasimende eminyakeni engaphezu kweshumi edlule.Nokho-ke eminyakeni yamuva nje lolu daba seluthathelwe phezulu ngabashuki.
Kuzo zombili izikhumba ezinkulu nezincane, ukugxila bekulokhu kushintshela ekuhlolweni kokuqukethwe kwamahhala kwe-formaldehyde.Abanye abakhiqizi besikhumba bazohlola zonke iziqephu zesikhumba sabo esisanda kukhiqizwa ukuze baqinisekise ukuthi imikhiqizo yabo isezingeni elifanele.
Kubantu abaningi embonini yesikhumba, ukuqashelwa kwendlela yokwehlisa okuqukethwe kwe-formaldehyde yamahhala esikhumbeni kwenziwe kwacaca——

Umhlahlandlela wokugwema imibono eyiphutha|Isincomo sesinqumo sezinsiza zokucwilisa ezichwepheshile
Ama-surfactants ayisistimu eyinkimbinkimbi, nakuba wonke angase abizwe ngokuthi ama-surfactants, ukusetshenziswa kwawo okuqondile nokusetshenziswa kwawo kungase kwehluke ngokuphelele.Isibonelo, ngesikhathi senqubo yokushuka, ama-surfactants angasetshenziswa njenge-ejenti yokungena, i-leveling agent, ukumanzisa umhlane, ukususa amafutha, ukukhuluphala, ukuthambisa kabusha, ukufaka emulsifying noma imikhiqizo yokuhlanza.
Kodwa-ke, lapho ama-surfactants amabili anemiphumela efanayo noma efanayo, kungase kube nokudideka okuthile.
I-ejenti yokucwilisa kanye ne-ejenti yokwehlisa amafutha yizinhlobo ezimbili zemikhiqizo ye-surfactant evame ukusetshenziswa ngesikhathi sokucwiliswa.Ngenxa yezinga elithile lokuwasha kanye nekhono lokumanzisa lama-surfactants, ezinye izimboni zingayisebenzisa njengemikhiqizo yokuwasha nokucwiliswa emanzini.Kodwa-ke, ukusetshenziswa kwe-agent ekhethekile yokucwiliswa kwe-ionic empeleni kubalulekile futhi akunakuthathelwa indawo.

Uhlelo lwesinqumo lwangaphambi kokushukwa kwe-Efficiency-Balance |Isincomo somkhiqizo esiphezulu sesinqumo
Ukubambisana kweqembu elihlakaniphile kungaletha umsebenzi ophumelelayo, kuyafana nokushukwa kwesikhumba.Isethi yemikhiqizo eyisipesheli neyenziwe ngezifiso ingasiza inqubo yokushuka futhi ikhiphe imiphumela oyifunayo.
Njengoba sonke sazi, ukufaka u-liming kuyinqubo ebaluleke kakhulu ngesikhathi sokusebenza kwe-beamhouse.Kulesi simo, imikhiqizo ehlanganisiwe enganikeza ukusebenza kahle, ukuzinza nokuphepha kungaba yisinqumo esingcono kakhulu sohlelo lokusebenza ekusebenzeni kwe-beamhouse.—-

I-ejenti yokushuka ye-polymer esebenza nge-Ultra kanye nesisindo se-molecular 'Eyingqayizivele' |Isincomo somkhiqizo esiphezulu sesinqumo
isisindo samangqamuzana womkhiqizo we-polymer
Emakhemikhalini esikhumba, omunye wemibuzo ethinteka kakhulu engxoxweni yemikhiqizo ye-polymer ukuthi, isimo sezulu umkhiqizo umkhiqizo omncane noma we-macro-molecule.
Ngoba phakathi kwemikhiqizo ye-polymer, isisindo samangqamuzana (ukuba nembe, isilinganiso sesisindo samangqamuzana. umkhiqizo we-polymer uqukethe izingxenye ezincane kanye ne-macro-molecule, ngakho-ke uma kukhulunywa ngesisindo samangqamuzana, ngokuvamile kubhekisela esilinganisweni sesisindo samangqamuzana.) Isisekelo sezisekelo zezakhiwo zomkhiqizo, kungase kuthinte ukugcwaliswa komkhiqizo, indawo engena ngaphakathi kanye nesibambo esithambile nesithambile sesikhumba ongasinikeza.Kunjalo, indawo yokugcina yomkhiqizo we-polymer ihlobene nezici ezihlukahlukene ezifana ne-polymerization, ubude beketango, ukwakheka kwamakhemikhali, ukusebenza, amaqembu e-hydrophilic, njll. Isisindo se-molecule asikwazanga ukuthathwa njengereferensi yodwa yendawo yomkhiqizo.
Isisindo samangqamuzana eningi lama-ejenti okubuyisela kabusha i-polymer emakethe singama-20000 kuya ku-100000 g/mol, izakhiwo zemikhiqizo enesisindo se-molecular ngaphakathi kwalesi sikhathi sibonisa impahla elinganiselayo.Kodwa-ke, isisindo se-molecular yemikhiqizo emibili ye-Decision singaphandle kwalesi sikhawu ngokuphambene.

Ukushesha kokukhanya okuhle kakhulu |Isincomo esiphezulu sesinqumo somkhiqizo we-sytan
Kukhona njalo izingcezu zakudala esizithola empilweni yethu ezisenza simamatheke njalo uma sizicabanga.Njengalezo zibhuzu zesikhumba ezimhlophe ezithokomele kakhulu ekhabetheni lakho lezicathulo.
Kodwa-ke, kuyakukhathaza ngezinye izikhathi ukukhumbula ukuthi ngokuhamba kwesikhathi, amabhuzu akho owathandayo ngeke esaba mhlophe futhi acwebezele, futhi kancane kancane azoguga futhi abe phuzi.
Manje ake sithole ukuthi yini ebangela ukuphuzi kwesikhumba esimhlophe——Ngo-1911 AD uDkt. Stiasny usungule inoveli yokwenziwa ye-tannin engangena esikhundleni se-tannin yemifino.Uma kuqhathaniswa ne-tannin yemifino, i-tannin yokwenziwa kulula ukuyikhiqiza, inempahla enkulu yokushuka, umbala okhanyayo kanye nokungena kahle.Ngakho-ke isithathe isikhundla esibalulekile embonini yokushukwa kwesikhumba phakathi neminyaka eyikhulu yentuthuko.Kubuchwepheshe besimanje bokushuka, lolu hlobo lwe-tannin yokwenziwa lusetshenziswa cishe kuzo zonke izihloko.
Ngenxa yokwakheka nokusetshenziswa kwayo okuhlukile, kuvame ukubizwa nge-synthetic tannin, i-phenolic tannin, i-sulfonic tannin, i-disperse tannin, njll. Okujwayelekile kwalawa ma-tannins ukuthi i-monomer yawo imvamisa iyisakhiwo samakhemikhali e-phenolic.
