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.

Impahla enhle kakhulu yokuhlanza amafoam, gcina isibambo sikhululekile｜Isiphakamiso sesinqumo somkhiqizo ofanele we-DESOPON SK70
Ayini amagwebu?
Ziyimilingo entanta ngaphezu kwezinkanyezi zothingo;
Ziyizinto ezikhazimulayo ezinweleni zomuntu esimthandayo;
Yimizila eshiywa ngemuva lapho ihlengethwa licwila olwandle oluluhlaza okwesibhakabhaka olujulile…Kubashuki besikhumba, amagwebu abangelwa ukwelashwa ngemishini (ngaphakathi kwezigubhu noma ngama-paddle), okufaka umoya ngaphakathi kwezingxenye ze-surfactant zoketshezi olusebenzayo futhi kwakha ingxube yegesi noketshezi.
Amagwebu awanakugwenywa ngesikhathi senqubo yokumanzisa. Lokho kungenxa yokuthi, enqubweni yokumanzisa, ikakhulukazi esigabeni sokubuyiselwa kwe-tan, amanzi, ama-surfactant kanye nokwelashwa kwemishini kuyizinto ezintathu eziyinhloko ezibangela amagwebu, kodwa lezi zinto ezintathu zikhona cishe kuyo yonke inqubo.Phakathi kwezici ezintathu, i-surfactant ingenye yezinto ezibalulekile ezisetshenziswa ngesikhathi senqubo yokushiswa kwesikhumba. Ukumanzisa okufanayo nokuzinzile koqweqwe kanye nokungena kwamakhemikhali oqweqweni konke kuncike kukho. Kodwa-ke, inani elikhulu le-surfactant lingabangela izinkinga zamagwebu. Amagwebu amaningi kakhulu angabangela izinkinga zokuqhubeka kwenqubo yokushiswa kwesikhumba. Isibonelo, kungathinta ukungena okulinganayo, ukumuncwa, kanye nokuqina kwamakhemikhali.

I-fatliquor yokwenziwa ethambile kakhulu i-DESOPON USF | Izincomo ze-Decision Premium
Ukuthamba
Emagqumeni ase-Ecuador kumila utshani obubizwa ngokuthi i-toquilla, iziqu zalo ezingalukwa zibe yizigqoko ngemva kokwelashwa okuthile. Lesi sigqoko sasithandwa yizisebenzi zasePanama Canal ngoba sasilula, sithambile futhi siphefumula kalula, futhi saziwa ngokuthi “isigqoko sasePanama”. Ungayigoqa yonke into, uyifake ngendandatho bese uyivula ngaphandle kokwephuka. Ngakho-ke imvamisa ipakishwa kusilinda bese igoqwa uma ingagqokwa, okwenza kube lula ukuyiphatha.
Esinye sezithombe ezidumile kakhulu zikaBernini yi-"Pluto Snatching Persephone" eyisimangaliso, lapho uBernini adala khona okungenzeka ukuthi imabula "ethambile kakhulu" emlandweni wesintu, eveza ubuhle obukhulu bemabula "ngokuthamba" kwayo.
Ukuthamba kuwumbono oyisisekelo onikeza abantu umuzwa wobuwena. Abantu bathanda ukuthamba, mhlawumbe ngoba akusilethisi ingozi noma ukulimala, kodwa kusilethela ukuphepha nenduduzo kuphela. Ukube wonke amasofa emakhaya aseMelika ayeyifenisha yaseShayina yokhuni oluqinile, kumelwe ukuba bekungeke kube nama-sofa amaningi kangaka, akunjalo?
Ngakho-ke, ngesikhumba, ubumnene bulokhu bungenye yezimpawu eziqashelwa kakhulu ngabathengi. Kungakhathaliseki ukuthi yizingubo, ifenisha, noma isihlalo semoto.
Umkhiqizo osebenza kahle kakhulu wokwenza isikhumba ube mnene yi-fatliquor.
Ukuthamba kwesikhumba kuwumphumela kunokuba kube yinhloso ye-fatliquor, okuwukuvimbela isakhiwo sefayibha ukuthi singanamatheli kabusha ngesikhathi senqubo yokomisa (yokuphelelwa amanzi emzimbeni).
Kodwa noma kunjalo, ukusetshenziswa kwama-fatliquors, ikakhulukazi lawo emvelo athile, kungabangela isikhumba esithambile nesikhululekile kakhulu. Kodwa-ke, kunezinkinga futhi: ama-fatliquors amaningi emvelo anephunga elibi noma aphuzi ngenxa yenani elikhulu lama-bond angagcwali esakhiweni sawo. Ama-fatliquors okwenziwa, ngakolunye uhlangothi, awahlushwa yile nkinga, kodwa avame ukungabi mnene futhi akhululekile njengoba kudingeka.I-Decision inomkhiqizo owodwa oxazulula le nkinga futhi ufeze ukusebenza okungavamile:
I-DESOPON USFI-fatliquor yokwenziwa ethambile kakhulu
Sikwenze kwaba mnene ngangokunokwenzeka -
