Inkcazelo yemveliso yeDESOATEN SC – Ikhemistri yesikhumba eguqukayo:
I-DESOATEN SC yimveliso yekhemikhali yesikhumba entsha eveliswa, yaphuhliswa kwaye ithengiswa ngumzi-mveliso wethu opheleleyo weekhemikhali zesikhumba. Le mveliso iphambili inikezela ngeenzuzo ezahlukeneyo zokuphucula ulusu xa kuthelekiswa neearhente zendabuko zokuthambisa isikhumba zepolymer, kubandakanya ukumelana nokumanzi okugqwesileyo, amandla omzimba aphuculweyo, ukugcwala kolusu okuphuculweyo, kunye namava angcono okuchukumisa. Yenzelwe ngokukodwa ishishini lokuthambisa isikhumba, i-DESOATEN SC ayilula nje ukuyisebenzisa kodwa ikwanceda ukufunxa... -
Indlela yonke eya kwihlabathi 'elingena-formaldehyde' | Ingcebiso yeemveliso zochungechunge lwe-amino resin zeSigqibo
Impembelelo ebangelwa yi-free formaldehyde eveliswa ngexesha lenkqubo yokutshiswa kwesikhumba ikhankanyiwe ziinkampani zokuthunga kunye nabathengi kwiminyaka engaphezu kweshumi eyadlulayo. Nangona kunjalo, kule minyaka idlulileyo kuphela apho le ngxaki ithathelwe ingqalelo kakhulu ngabathungi bokuthunga.
Kwiindawo zokuthunga ezinkulu nezincinci, ingqwalasela ibikukuvavanya umxholo we-formaldehyde okhululekileyo. Ezinye iindawo zokuthunga ziya kuvavanya yonke ibhetshi yesikhumba sazo esitsha ukuqinisekisa ukuba iimveliso zazo zisemgangathweni.
Kubantu abaninzi abakwishishini lesikhumba, ukuqonda indlela yokunciphisa umxholo we-free formaldehyde kwisikhumba kuye kwacaciswa——

I-arhente yokuthanjiswa kwe-polymer ene-Ultra performance kunye nobunzima be-molecular 'Unique' | Ingcebiso yemveliso efanelekileyo yeSigqibo
ubunzima bemolekyuli yemveliso yepolymer
Kwikhemikhali yesikhumba, omnye wemibuzo exhalabisayo kwingxoxo yeemveliso zepolymer kukuba, imozulu yemveliso yimveliso encinci okanye enkulu yemolekyuli.
Kuba phakathi kweemveliso zepolymer, ubunzima bemolekyuli (ukuba ngokuchanekileyo, ubunzima bemolekyuli obuqhelekileyo. imveliso yepolymer iqulethe izinto ezincinci kunye ne-macro-molecule, ngoko ke xa kuthethwa ngobunzima bemolekyuli, kudla ngokubhekisa kubunzima bemolekyuli obuqhelekileyo.) yenye yezona zinto ziphambili zeempawu zemveliso, inokuchaphazela ukuzaliswa kwemveliso, ipropati yokungena kunye nesiphatho esithambileyo nesithambileyo sesikhumba esinokusinika.Kakade ke, ipropati yokugqibela yemveliso yepolymer inxulumene nezinto ezahlukeneyo ezifana ne-polymerization, ubude betsheyini, ulwakhiwo lweekhemikhali, imisebenzi, amaqela athanda amanzi, njl. Ubunzima bemolekyuli abunakubonwa njengokuphela kwesalathiso sepropati yemveliso.
Ubunzima beemolekyuli ze-polymer retanning agents ezininzi ezithengiswayo zimalunga ne-20000 ukuya kwi-100000 g/mol, iipropati zeemveliso ezinobunzima beemolekyuli ngaphakathi kwesi sithuba zibonisa ipropati elungeleleneyo ngakumbi.Nangona kunjalo, ubunzima beemolekyuli zeemveliso ezimbini zeDecision bungaphandle kwesi sithuba kwicala elahlukileyo.

Ukukhawuleza kokukhanya okugqwesileyo | Ingcebiso efanelekileyo yesigqibo semveliso ye-syntan
Kukho izinto zakudala esizifumanayo ebomini bethu ezisenza sonwabe ngalo lonke ixesha xa sizicinga. Njengeebhutsi zesikhumba ezimhlophe ezikhululekileyo kwikhabhathi yezihlangu zakho.
Nangona kunjalo, ngamanye amaxesha kuyakhathaza ukukhumbula ukuba ngokuhamba kwexesha, izihlangu zakho ozithandayo azisayi kuba mhlophe kwaye zikhazimle, kwaye ziya kuba zindala kwaye zibe tyheli kancinci kancinci.
Ngoku masifumanise ukuba yintoni ebangela ukuba isikhumba esimhlophe sibe tyheli——Ngo-1911 AD uGqr. Stiasny uphuhlise i-tannin entsha yokwenziwa enokuthatha indawo ye-tannin yemifuno. Xa kuthelekiswa ne-tannin yemifuno, i-tannin yokwenziwa kulula ukuyivelisa, ineempawu ezintle zokwenziwa kwesikhumba, umbala okhanyayo kunye nokungeneka kakuhle. Ngaloo ndlela ithathe indawo ebalulekileyo kwishishini lokwenziwa kwesikhumba kwiminyaka elikhulu yophuhliso. Kwiteknoloji yanamhlanje yokwenziwa kwesikhumba, olu hlobo lwe-tannin yokwenziwa lusetyenziswa phantse kuzo zonke izinto.
Ngenxa yesakhiwo sazo esahlukileyo kunye nokusetyenziswa kwazo, zihlala zibizwa ngokuba yi-synthetic tannin, i-phenolic tannin, i-sulfonic tannin, i-disperse tannin, njl. Isiqhelo sezi tannins kukuba i-monomer yazo idla ngokuba yi-phenolic chemical structure.

I-DESOATEN ARA I-Amphoteric Polymeric Tanning Agent kunye ne-DESOATEN ARS I-Amphoteric Synthetic Tanning Agent | Iingcebiso zePremium zeSigqibo
Kukho umlinganiswa ogama linguWang Yangming kwiMing Dynasty. Xa wayengekho etempileni, waseka isikolo sengqondo; xa wayeligosa labazali, wayenceda uluntu; xa ilizwe lalikwingxaki, wasebenzisa ubulumko bakhe nesibindi sakhe phantse eyedwa ukuze aphelise uvukelo aze athintele ilizwe ukuba lingatshatyalaliswa yimfazwe yamakhaya. “Ukumisela ubuhle, isidima kunye nentetho akulona ukhetho lwesibini kwiminyaka engamawaka amahlanu edlulileyo.” Ubulumko obukhulu bukaWang Yangming bukwinyani yokuba wayenobubele ngakumbi xa ejongene nabantu abalungileyo kwaye enobuqhetseba ngakumbi xa ejongene nabavukeli abanobuqhetseba.
Ihlabathi alikho kwicala elinye, lidla ngokuba li-hermaphroditic. Njengee-amphoteric tanning agents phakathi kweekhemikhali zesikhumba. Ii-amphoteric tanning agents zii-tanning agents ezineqela le-cationic kunye neqela le-anionic kwisakhiwo sekhemikhali esifanayo - xa i-pH yenkqubo iyindawo ye-isoelectric ye-tanning agent. I-tanning agent ayibonisi mpawu ze-cationic okanye ze-anionic;
Xa i-pH yenkqubo ingaphantsi kwe-isoelectric point, iqela le-anionic le-agent ye-tanning liyakhuseleka kwaye lithatha uphawu lwe-cationic, kwaye ngokuchaseneyo. -
Yenza inqaku le-floater libe lilinganayo ngakumbi, i-DESOATEN ACS | Iingcebiso zePremium zeSigqibo
Ukuba uqhuba ngemoto eXinjiang, landela iLianhuo Expressway ubuyela eUrumqi, emva kokuwela iBhulorho yaseGuozigou, uza kudlula kumngxuma omde, kwaye kwangoko xa uphuma kumngxuma - isibhakabhaka esikhulu esicacileyo siya kungena emehlweni akho.
Kutheni siwathanda amachibi? Mhlawumbi kungenxa yokuba umphezulu okhazimlayo wechibi usinika umoya wokuzola 'oguquguqukayo', kungekhona okuqinileyo njengamanzi omthombo okanye okungcolileyo njengengxangxasi, kodwa okuzinzileyo nokuphilayo, ngokuhambelana nobuhle baseMpuma bokulinganisela nokuzihlolisisa.
I-Floater mhlawumbi yindlela yokwenza ulusu ebonisa ubuhle bayo.
I-Floater yindlela eqhelekileyo yokwenziwa kwesikhumba ngenxa yesiphumo sayo esikhethekileyo sengqolowa, esinika umdla wendalo nokhululekileyo kwisitayile. Isetyenziswa kakhulu kwizihlangu ezikhululekileyo, izihlangu zangaphandle kunye nefenitshala yesikhumba sesofa. Ikwasetyenziselwa ukuphucula isitayile kunye nokuphucula umgangatho wesikhumba, njengoko ukuqhekeka kufihla umonakalo wesikhumba.Kodwa i-floater elungileyo ikwabeka iimfuno eziphezulu kwi-rawhide yokuqala. Ifuna ukulingana okuhle kwe-wetblue emanzi, kungenjalo inokubangela iingxaki zokuqhekeka okungalinganiyo. Nangona kunjalo, nokuba i-wetblue iphathwe kakuhle, umahluko kwizikhumba zokuqala zezilwanyana, ingakumbi umahluko omkhulu kumqolo nakwisisu esisecaleni, unokwenza nokuba iphule umceli mngeni omkhulu wesitayile se-floater. Ngoko ke, ukuphendula le ngxaki, iqela leSigqibo lizise isisombululo esitsha.
