Inkcazo yemveliso ye-Chesotict Shemistry Lengsists:
I-SOCOED SC yindawo entsha yemichiza yekhemikhali evelisiweyo, iphuhlisiwe kwaye ithengiswa ngumzi mveliso wesikhumba esibanzi. Le mveliso iphambili ibonelela ngoluhlu lwezibonelelo zokuphucula isikhumba xa kuthelekiswa neearhente zokungena kwamanzi, kubandakanya ukumelana kwamanzi, ukuphuculwa kwesikhumba, kunye namava aphuculweyo, kunye namava aphezulu akhuthazayo. Iyenzelwe ngqo ishishini lesikhumba, i-SOOTED SCATATE ilula kuphela ukuba isetyenziselwe kodwa ikwaququzelele i-bensep ... -
Yonke indlela eya kwi-'Mfazwe' yehlabathi | Ukucebisa kweemveliso ze-Amino ze-Amino ze-Amino
Impembelelo ezibangelwe yi-formaldehyde yasimahla ngexesha lenkqubo yokutyibilika ikhankanywe yi-tanneries kunye nabaxumi ngaphezulu kweshumi elidlulileyo. Nangona kunjalo kwiminyaka yakutshanje kukho umba othathwe nzulu ngo-ntenters.
Zombini ezikhulu nezincinci, ukugxila kutshintshiwe kuvavanyo lwe-formaldehydehyde. Ezinye iitaneries ziya kuvavanya yonke i-batch yesikhumba sabo esisandul 'ukuveza ukuba iqinisekise ukuba iimveliso zabo zikwimigangatho.
Uninzi lwabantu kwishishini lesikhumba, ukuqonda kwendlela yokuthoba umxholo wefomaldehyaldehydedde yesikhumba yenziwe kakuhle--

I-Polymer Tanner Agent ye-Ultra yokuSebenzisa kunye 'ne-folecular eyodwa | Ingcebiso yeMveliso yeFowuni
I-Polymer imveliso yemolekyuli yemolekyuli
Kwimichiza yesikhumba, omnye wombuzo oxhalabisayo kwingxoxo yeemveliso zePolymer kukuba, imozulu iMveliso yimveliso encinci okanye i-macro-molecule.
Kuba phakathi kweemveliso zepolymer, ubunzima bemolekyuli (ukuba sichanekile, ubunzima bemoyaremu.Ewe kunjalo, ipropathi yokugqibela yemveliso yePolymer ihambelana nemiba eyahlukeneyo enjenge-polymerizazazazazazazazation, ubude be-chain, imilinganiselo ye-molek, i-Hydrophilic, njl.
Ubunzima bemolekyuli uninzi lweearhente zokubuyiselwa kwePolymer kwimakethi malunga ne-20000 ukuya kwi-100000 G / Mol, iipropathi zeemveliso ezinobunzima bemolekyuli phakathi kwethuba elipheleleyo.Nangona kunjalo, ubunzima beemolekyuli zeemveliso ezimbini zezigqibo zingaphandle kwethuba kwelinye icala.

Ukuzithoba kokukhawuleza | ISIQINISEKISO SESIQINISEKISO SOKUGQIBELA Imveliso ye-Syntan
Kuhlala kukho iziqwenga zeklasikhi esizifumana ebomini bethu ezisenza ukuba sincume ngalo lonke ixesha sicinga ngazo. Njengaloo roll supy shy goathe yesikhumba kwiKhabhinethi yakho yamaShundu.
Nangona kunjalo, kuyakukhulula ngamanye amaxesha ukukhumbula ukuba ngokuhamba kwexesha, iibhutsi zakho ozithandayo azisayi kuba mhlophe kwaye zibekile, kwaye ngokuthe ngcembe yayimdala kwaye ityheli.
Ngoku masifumanise ukuba yintoni eyona nto ityheli yengubo emhlophe yesikhumba--Ngo-1911 AD DR. Xa kuthelekiswa nemifuno eTanin, iTanin ye-Tanin kulula ukuyivelisa, inepropathi enkulu yokutsala, umbala okhanyisayo kunye nenyanga elungileyo. Yiyo loo nto ifikile kwisikhundla esibalulekileyo kwishishini lokutyibiliki ngaphezulu kwekhulu leminyaka yophuhliso. KwiTekhnoloji yeTekhnoloji ye-Tanning yanamhlanje, olu hlobo lwe-tannin yokwenziwa lusetyenziswa phantse kuwo onke amanqaku.
Ngenxa yesakhiwo sayo esahlukileyo kunye nesicelo, bahlala bebizwa ngokuba yi-synthetic tanin, i-pinonin tanin, i-Sulfoni Tannin, i-Sulfoni Tanin, i-Sul.

I-Arabed Ara Ara Arampleic Polymeric Polymeric Pening kunye ne-ArsOoded Ars Amphotetic Syntatic Syntatic Syntatic ye-Amputer | Izigqibo zePremiyamu zePremiyamu
Kukho umlinganiswa obizwa ngokuba yiWang yang Xa wayengekho etempileni, wasikelwa esikolweni sengqondo; Xa wayeligosa lomzali, wazuza uluntu; Xa ilizwe lisengxakini, wasebenzisa ubulumko nenkalipho yakhe phantse umntu omnye umntu ovuthiweyo kwaye uthintele ilizwe ukuba lingonakaliswa yimfazwe yamakhaya. "Ukuseka i-merit kunye nobuhle kunye nokuthetha akukho lula ukuba khetha ukhetho lwesibini kule minyaka mihlanu idlulileyo." Wang Yangming's great wisdom lies in the fact that he was kinder in the face of the good people and more cunning in the face of the cunning rebels.
Umhlaba awungqhinga omnye, ihlala iHermaphroditic. Kanye njengokuba iiarhente zokuntywila kwi-amphoteric ziphakathi kwamachiza esikhumba. Iiarhente zokuntywila ze-Amphoteric zinearhente yokutsibela eneqela lesiko kunye neqela le-aions kwisakhiwo esifanayo sekhemikhali - xa i-PH yenkqubo yeyokwaluvo lwe-isolylic version. Iarhente ye-Tanning ibonakalisa i-curicic okanye i-aidic yepropathi;
Xa i-PH yale nkqubo ingezantsi kwendawo ye-ISOCTRICT, iqela le-ANERIC learhente ye-Tanning likhuselwe kwaye lithatha umlinganiswa wesiko, kunye ne-vice. -
Yenza inqaku le-biloer ngaphezulu nangaphezulu, ii-desoineades ze-AC | Izigqibo zePremiyamu zePremiyamu
Ukuba uqhuba e-xinajiang, landela i-lianshuo i-Puotheo ibuyela eUrumqi, emva kokuwela ibhulorho ende, uya kuphuma kumjelo omde, kwaye okomzuzwana uphuma emehlweni akho.
Kutheni simthanda amachibi? Mhlawumbi ngenxa yokuba umphezulu wechibi usinika ingqondo 'yokuhamba' i-Dynamic ', ayingqinelani njengamanzi amdaka okanye ukungcola njengokuhamba kwamanzi, kodwa kuhambelana nokuphila nge-empuma yokumodareyitha kunye ne-introssiction.
Iidazi mhlawumbi kusenokuba sisitayile sesikhumba esibonisa kakuhle obu buhle.
I-Dlowater sisitayile esiqhelekileyo kwisikhumba ngenxa yesiphumo senkozo ekhethekileyo, enika inzala yendalo neyonwabisileyo. Isetyenziselwa kakhulu izihlangu eziqhelekileyo, izihlangu zangaphandle kunye nefanitshala ye-sofa. Ikwasetyenziselwa ukonyusa isitayile kwaye siphucule inqanaba lesikhumba, njengoko ikhefu lifihla umonakalo kwisikhumba.Kodwa intaka elungileyo ikwabeka iimfuno eziphezulu kwi-rawhide yeyokuqala. Ifuna ukudakumba okufanelekileyo kwendawo emanzi, kungenjalo kunokubangela iingxaki ezingalinganiyo. Nangona kunjalo, nokuba indawo emanziweyo inyangwa kakuhle, umahluko kwizikhumba zantlandlolo zezilwanyana, ngakumbi umahluko omkhulu kwi-ballies nakwiintsimbi zecala, unokwenza umngeni omkhulu wesitayile semibala. Ke ngenxa yokuphendula kule ngxaki, iqela lesigqibo lazise isisombululo esitsha.
