I-DESOATEN SC – I-Revolutionary Leather Chemistry Incazelo Yomkhiqizo:
I-DESOATEN SC iyinto entsha eyenziwe ngamakhemikhali esikhumba ekhiqizwa, yathuthukiswa futhi yathengiswa yifektri yethu ephelele yamakhemikhali esikhumba. Lo mkhiqizo othuthukisiwe unikeza izinzuzo eziningi zokuthuthukisa isikhumba uma kuqhathaniswa nezithako zendabuko zokushiswa kwesikhumba ze-polymer, okuhlanganisa ukumelana namanzi okuhle kakhulu, amandla athuthukisiwe ngokomzimba, ukugcwala kwesikhumba okuthuthukisiwe, kanye nokuhlangenwe nakho okunamandla okuthinteka. I-DESOATEN SC eyenzelwe ngqo imboni yokushiswa kwesikhumba, ayilula nje kuphela ukuyisebenzisa kodwa futhi yenza kube lula ukumunca... -
Indlela eya ezweni 'elingenayo i-formaldehyde' | Izincomo zemikhiqizo yochungechunge lwe-amino resin ye-Decision
Umthelela obangelwa yi-free formaldehyde ekhiqizwa ngesikhathi senqubo yokushiswa kwesikhumba ukhulunywe ngabashisi besikhumba kanye namakhasimende eminyakeni engaphezu kweyishumi edlule. Kodwa-ke, eminyakeni yamuva nje kuphela lapho le ndaba ithathwe ngokungathi sína ngabashisi besikhumba.
Kuzo zombili izindawo zokushuna izikhumba ezinkulu nezincane, ukugxila kuye kwaba ukuhlola okuqukethwe kwe-formaldehyde yamahhala. Ezinye izindawo zokushuna izikhumba zingahlola yonke inqwaba yesikhumba sazo esisanda kukhiqizwa ukuqinisekisa ukuthi imikhiqizo yazo ihambisana nezindinganiso.
Kwabaningi embonini yesikhumba, ukuqonda ukuthi unganciphisa kanjani okuqukethwe yi-formaldehyde yamahhala esikhumbeni kuye kwacaca kakhulu——

I-polymer tanning agent enekhono eliphezulu kanye nesisindo sama-molecule 'esiyingqayizivele' | Isiphakamiso somkhiqizo esihle kakhulu sesinqumo
isisindo sama-molecule somkhiqizo we-polymer
Kumakhemikhali esikhumba, omunye wemibuzo ebaluleke kakhulu engxoxweni yemikhiqizo ye-polymer ukuthi, isimo sezulu sokuthi umkhiqizo ungumkhiqizo we-micro noma we-macro-molecule.
Ngoba phakathi kwemikhiqizo ye-polymer, isisindo sama-molecule (uma siqondile, isisindo sama-molecule esimaphakathi. umkhiqizo we-polymer uqukethe izingxenye ezincane nezinkulu zama-molecule, ngakho-ke uma kukhulunywa ngesisindo sama-molecule, ngokuvamile kubhekisela esisindweni sama-molecule esimaphakathi.) kungenye yezisekelo eziyinhloko zezakhiwo zomkhiqizo, kungathinta ukugcwaliswa komkhiqizo, impahla yokungena kanye nesibambo esithambile nesithambile sesikhumba esingasinika.Vele, isici sokugcina somkhiqizo we-polymer sihlobene nezici ezahlukahlukene ezifana ne-polymerization, ubude beketanga, isakhiwo samakhemikhali, ukusebenza, amaqembu athanda amanzi, njll. Isisindo sama-molecule asinakubhekwa njengokubhekisela kuphela kwesici somkhiqizo.
Isisindo sama-molecule amaningi ama-polymer retanning agents emakethe singaba ngu-20000 kuya ku-100000 g/mol, izakhiwo zemikhiqizo enesisindo sama-molecule ngaphakathi kwalesi sikhathi zibonisa isici esilinganiselayo.Kodwa-ke, isisindo sama-molecule semikhiqizo emibili ye-Decision singaphandle kwalesi sikhawu ngakolunye uhlangothi.

Ukushesha kokukhanya okuhle kakhulu | Isincomo esihle kakhulu sesinqumo somkhiqizo we-syntan
Kuhlala kukhona izingcezu zakudala esizitholayo empilweni yethu ezisenza smile njalo uma sicabanga ngazo. Njengalezo zibhuzu zesikhumba ezimhlophe ezikhululekile kakhulu ekhabetheni lakho lezicathulo.
Kodwa-ke, kuyakhathaza ngezinye izikhathi ukukhumbula ukuthi ngokuhamba kwesikhathi, amabhuzu akho owathandayo ngeke esamhlophe futhi acwebezele, futhi kancane kancane azoguga futhi abe phuzi.
Manje ake sithole ukuthi yini engemuva kokuphuzi kwesikhumba esimhlophe——Ngo-1911 AD uDkt. Stiasny wakha i-tannin entsha yokwenziwa engathatha indawo ye-tannin yemifino. Uma kuqhathaniswa ne-tannin yemifino, i-tannin yokwenziwa kulula ukuyikhiqiza, inempahla enhle yokushiswa kwesikhumba, umbala okhanyayo kanye nokungeneka okuhle. Ngakho-ke isithathe isikhundla esibalulekile embonini yokushiswa kwesikhumba eminyakeni eyikhulu yentuthuko. Ebuchwephesheni besimanje bokushiswa kwesikhumba, lolu hlobo lwe-tannin yokwenziwa lusetshenziswa cishe kuzo zonke izinto.
Ngenxa yesakhiwo sazo esihlukile kanye nokusetshenziswa kwazo, zivame ukubizwa ngokuthi i-synthetic tannin, i-phenolic tannin, i-sulfonic tannin, i-disperse tannin, njll. Okujwayelekile kwalawa ma-tannins ukuthi i-monomer yawo ivame ukuba nesakhiwo samakhemikhali se-phenolic.

I-DESOATEN ARA I-Amphoteric Polymeric Tanning Agent kanye ne-DESOATEN ARS I-Amphoteric Synthetic Tanning Agent | Izincomo Eziphezulu Zesinqumo
Kukhona umlingiswa ogama lakhe linguWang Yangming eMbusweni WamaMing. Ngesikhathi engekho ethempelini, wasungula isikole sengqondo; ngesikhathi eseyisikhulu sabazali, wazuzisa umphakathi; lapho izwe lisenkingeni, wasebenzisa ukuhlakanipha kwakhe nesibindi sakhe cishe eyedwa ukuthulisa ukuvukela nokuvimbela izwe ukuba lingabhujiswa yimpi yombango. “Ukusungula ubuhle, ubuhle kanye nenkulumo akuyona neze inketho yesibili eminyakeni eyizinkulungwane ezinhlanu edlule.” Ukuhlakanipha okukhulu kukaWang Yangming kuseqinisweni lokuthi wayenomusa kakhulu phambi kwabantu abalungile futhi enobuqili kakhulu phambi kwabavukeli abanobuqili.
Umhlaba awukho ohlangothini olulodwa, uvame ukuba yi-hermaphroditic. Njengezinto ezithinta isikhumba ezisebenzisa i-amphoteric phakathi kwamakhemikhali esikhumba. Izinto ezithinta isikhumba ezisebenzisa i-amphoteric ziyizinto ezithinta isikhumba ezineqembu le-cationic kanye neqembu le-anionic esakhiweni esifanayo samakhemikhali - lapho i-pH yesistimu iyiphuzu eliqondile le-isoelectric le-agent yokuthinta isikhumba. i-agent yokuthinta isikhumba ayibonisi izakhiwo ze-cationic noma ze-anionic;
Uma i-pH yesistimu ingaphansi kwephuzu le-isoelectric, iqembu le-anionic le-agent yokuthamba liyavikelwa futhi lithatha uhlamvu lwe-cationic, kanye nokuphikisana nalokho. -
Yenza isihloko se-floater sibe silingana kakhudlwana, i-DESOATEN ACS | Izincomo ze-Premium ze-Decision
Uma ushayela eXinjiang, landela iLianhuo Expressway ubuyele e-Urumqi, ngemva kokuwela iGuozigou Bridge, uzodlula emhubheni omude, futhi ngokushesha nje lapho uphuma emhubheni – kuzongena amehlo akho nge-crystal clear blue enkulu.
Kungani siwathanda amachibi? Mhlawumbe ngoba ubuso obukhazimulayo bechibi businika umuzwa wokuzola 'okuguquguqukayo', hhayi okuqinile njengamanzi omthombo noma okungcolile njengempophoma, kodwa okuvinjelwe futhi okunempilo, okuhambisana nobuhle baseMpumalanga bokulinganisela nokuzihlolisisa.
I-Floater cishe isitayela sesikhumba esibonakalisa kahle lobu buhle.
I-Floater isitayela esivamile sesikhumba ngenxa yomphumela okhethekile wezinhlamvu, onikeza isithakazelo sesitayela semvelo nesikhululekile. Isetshenziswa kakhulu ezicathulweni ezivamile, ezicathulweni zangaphandle kanye nesikhumba sesofa sefenisha. Iphinde isetshenziswe ukuthuthukisa isitayela nokuthuthukisa izinga lesikhumba, njengoba ukuphuka kufihla umonakalo wesikhumba.Kodwa i-floater enhle ibeka izidingo eziphezulu ku-rawhide yokuqala uqobo. Idinga ukulingana okuhle kwe-wetblue emanzi, ngaphandle kwalokho ingabangela kalula izinkinga zokuphuka okungalingani. Kodwa-ke, noma ngabe i-wetblue iphathwe kahle, ukuhlukahluka kwezikhumba zokuqala zezilwane, ikakhulukazi umehluko omkhulu emhlane naseziswini eziseceleni, kungenza ngisho nokuphula inselele enkulu yesitayela se-floater. Ngakho-ke ekuphenduleni le nkinga, ithimba le-Decision lethule ikhambi elisha.
