I-DESOATEN SC-Inkcazo yeMveliso yeMveliso yeLeather yeLeather:
I-DESOATEN SC yimathiriyeli yeekhemikhali zesikhumba eveliswayo, yaphuhliswa yaza yathengiswa ngumzi-mveliso wethu wemichiza wesikhumba obanzi. Le mveliso ihambele phambili ibonelela ngoluhlu lweenzuzo zokuphucula ufele xa kuthelekiswa neearhente zemveli zokusukwa kwepolymer, kubandakanya nokuxhathisa okugqwesileyo kwamanzi, ukomelela komzimba okuphuculweyo, ukugcwala kwesikhumba, kunye namava abambekayo aphezulu. Yenzelwe ngokukodwa ishishini lofele, iDESOATEN SC ayilulanga kuphela ukuyisebenzisa kodwa ikwaququzelela ukufunxa... -
Yonke indlela eya kwihlabathi 'elingenayo i-formaldehyde' | Isindululo seemveliso ze-amino resin zeSigqibo
Impembelelo ebangelwa yi-formaldehyde yamahhala eveliswa ngexesha lenkqubo yokutshisa ikhankanyiwe yi-tanneries kunye nabathengi ngaphezu kweminyaka elishumi edlulileyo. Nangona kunjalo kuphela kwiminyaka yakutshanje lo mbandela uthatyathwe nzulu ngabasuki.
Kuzo zombini ii-tanneries ezinkulu nezincinci, ugxininiso luye lwatshintshela kuvavanyo lomxholo wasimahla we-formaldehyde. Ezinye ii-tanneries ziya kuvavanya yonke ibhetshi yesikhumba sabo esandula ukuveliswa ukuqinisekisa ukuba iimveliso zabo zisemgangathweni.
Kubantu abaninzi kwishishini lesikhumba, ukuqonda indlela yokuthoba umxholo we-formaldehyde yasimahla kwisikhumba yenziwe yacaca gca——

Iarhente yokulukwa kwePolymer esebenza ngeUltra kunye nobunzima bemolekyuli 'Yodwa' | Isigqibo esona sindululo semveliso
imveliso polymer ubunzima molekyuli
Kwimichiza yesikhumba, omnye wemibuzo echaphazelekayo kwingxoxo yeemveliso zepolymer kukuba, isimo sezulu imveliso yimveliso encinci okanye i-macro-molecule.
Ngenxa yokuba phakathi kweemveliso zepolymer, ubunzima bemolekyuli (ukuchaneka, ubunzima obuphakathi kwemolekyuli. imveliso yepolymer iqulathe amasuntswana amancinci kunye ne-macro-molecule, ke xa kuthethwa ngobunzima bemolekyuli, ihlala ibhekisa kubunzima obuqhelekileyo bemolekyuli.) yenye yeziseko ezisisiseko zepropathi yemveliso, inokuchaphazela ukuzaliswa kwemveliso, ipropathi egqobhozayo kunye nesibambo esithambileyo nesithambileyo esinokusikhulula.Ngokuqinisekileyo, ipropati yokugqibela yemveliso ye-polymer inxulumene nezinto ezahlukeneyo ezifana ne-polymerization, ubude bekhonkco, ukwakhiwa kweekhemikhali, ukusebenza, amaqela e-hydrophilic, njl.
Ubunzima bemolekyuli yoninzi lweearhente zokulahla i-polymer kwimarike zijikeleze i-20000 ukuya kwi-100000 g/mol, iipropathi zeemveliso ezinobunzima bemolekyuli ngaphakathi kweli thuba zibonisa ipropathi elungeleleneyo.Nangona kunjalo, ubunzima bemolekyuli yeemveliso ezimbini zeSigqibo bungaphandle kweli xesha lokuphumla kwelinye icala.

Ukukhanya okugqwesileyo ngokukhawuleza | Isigqibo esona sincomo semveliso yesivakalisi
Kuhlala kukho iziqwenga zakudala esizifumana ebomini bethu ezisenza sincume qho xa sicinga ngazo. Njengezo bhutsi zesikhumba ezimhlophe ezipholileyo kwikhabhathi yakho yezihlangu.
Nangona kunjalo, kuyakukhathaza ngamanye amaxesha ukukhumbula ukuba ngokuhamba kwexesha, iibhutsi zakho ozithandayo azisayi kuba mhlophe kwaye zibengezele, kwaye ngokuthe ngcembe ziya kukhula zibe tyheli.
Ngoku masifumanise ukuba yintoni esemva kolusu olumhlophe——Ngo-1911 AD uGqr Stiasny uye wavelisa inoveli ye-tannin eyenziweyo enokuthi ithathe indawo ye-tannin yemifuno. Xa kuthelekiswa nemifuno ye-tannin, i-synthetic tannin kulula ukuyivelisa, inepropati enkulu yokutshisa, umbala okhanyayo kunye nokungena kakuhle. Yiyo ke loo nto ifikelele kwisikhundla esibalulekileyo kushishino lokutshisa ulusu kwiminyaka elikhulu yophuhliso. Kwitekhnoloji yolusu lwangoku, olu hlobo lwe-tannin yokwenziwa lusetyenziswa phantse kuwo onke amanqaku.
Ngenxa yesakhiwo sayo esahlukileyo kunye nokusetyenziswa kwayo, zidla ngokubizwa ngokuba yi-tannin yokwenziwa, i-phenolic tannin, i-sulfonic tannin, i-disperse tannin, njl njl. Ukuqheleka kwezi tannins kukuba i-monomer yabo idla ngokuba yi-phenolic chemical structure.

DESOATEN ARA Amphoteric Polymeric Tanning Agent and DESOATEN ARS Amphoteric Synthetic Tanning Agent | ISigqibo seNgcebiso zeNtlawulo yaNyanga le
Kukho umlinganiswa obizwa ngokuba nguWang Yangming kwiMing Dynasty. Uthe akumka etempileni, waseka imfundiso yengqondo; xa wayeligosa labazali, wayenceda uluntu; xa ilizwe lalisebugxwayibeni, wasebenzisa ubulumko nenkalipho ukuze aphelise eyedwa loo mvukelo waza wathintela elo lizwe ukuba lonakaliswe yimfazwe yamakhaya. "Ukumisela ukufaneleka kunye nokulunga kunye nentetho ayiyonto yesibini kukhetho lwesibini kwiminyaka engamawaka amahlanu edlulileyo." Ubulumko obukhulu bukaWang Yangming buxhomekeke kwinto yokuba wayenobubele phambi kwabantu abalungileyo kwaye enobuqili ngakumbi phambi kwabavukeli abanobuqili.
Ihlabathi alikho cala-nye, lihlala liyi-hermaphroditic. Kanye njengee-amphoteric tanning agents phakathi kwemichiza yesikhumba. Ii-amphoteric tanning agents zi-amphoteric tanning agents ezineqela le-cationic kunye neqela le-anionic kwisakhiwo semichiza efanayo - xa i-pH yenkqubo iyindawo ye-isoelectric ye-agent e-agent. i-agent esusa ulusu ayibonisi iimpawu ze-cationic okanye i-anionic;
Xa i-pH yenkqubo ingaphantsi kwendawo ye-isoelectric, iqela le-anionic le-agent ye-tanning likhuselekile kwaye lithatha umlingiswa we-cationic, kwaye ngokuphambene noko. -
Yenza inqaku elidadayo ngakumbi, DESOATEN ACS | ISigqibo seNgcebiso zeNtlawulo yaNyanga le
Ukuba uqhuba e-Xinjiang, landela i-Lianhuo Expressway ebuyela e-Urumqi, emva kokuwela iBhulorho yaseGuozigou, uya kudlula kwitonela elide, kwaye umzuzu uphuma kwi-tunnel - i-crystal eluhlaza okwesibhakabhaka iya kukhawuleza emehlweni akho.
Kutheni sithanda amachibi? Mhlawumbi ngenxa yokuba umphezulu ubengezelayo wechibi usinika imvakalelo yokuzola 'okuguquguqukayo', kungekhona okuqinileyo njengamanzi equla okanye ukungcoliseka okufana nengxangxasi, kodwa kuthintelwe kwaye kudlamkile, ngokuhambelana nobuhle baseMpuma bokumodareyitha kunye nokuzijonga.
I-Floater mhlawumbi sesona simbo sesikhumba esibonakalisa kakuhle obu bubuhle.
I-Floater yindlela eqhelekileyo yesikhumba ngenxa yesiphumo esikhethekileyo senkozo, esinika umdla wendalo kunye nesitayela esikhululekile. Isetyenziswa kakhulu kwizihlangu eziqhelekileyo, izihlangu zangaphandle kunye nesikhumba sesofa yefenitshala. Ikwasetyenziselwa ukuphucula isitayile kunye nokuphucula umgangatho wesikhumba, njengoko ikhefu lifihla umonakalo wesikhumba.Kodwa i-float elungileyo ikwabeka iimfuno eziphezulu kwi-rawhide yasekuqaleni ngokwayo. Ifuna ukulingana okulungileyo kwe-wetblue emanzi , ngaphandle koko kunokubangela iingxaki zekhefu ezingalinganiyo. Nangona kunjalo, nangona i-wetblue iphathwa kakuhle, ukuhluka kwezikhumba zokuqala zezilwanyana, ngokukodwa ukungafani okukhulu kwi-backbone kunye ne-bellies esecaleni, kungenza nokuba uphule umngeni omkhulu wesitayela se-float. Ngoko ukuphendula le ngxaki, iqela leSigqibo lizise isisombululo esitsha.
