Cov tshuaj polymer tanning uas muaj kev ua tau zoo heev thiab qhov hnyav molecular 'Unique' | Cov lus pom zoo zoo tshaj plaws ntawm Decision
qhov hnyav molecular ntawm cov khoom polymer
Hauv cov tshuaj tawv nqaij, ib qho lus nug txhawj xeeb tshaj plaws hauv kev sib tham txog cov khoom polymer yog tias, huab cua cov khoom yog cov khoom micro lossis macro-molecule.
Vim tias ntawm cov khoom polymer, qhov hnyav molecular (kom meej meej, qhov nruab nrab ntawm qhov hnyav molecular. ib yam khoom polymer muaj cov khoom me me thiab macro-molecule, yog li thaum hais txog qhov hnyav molecular, nws feem ntau yog hais txog qhov nruab nrab ntawm qhov hnyav molecular.) yog ib qho ntawm cov hauv paus tseem ceeb ntawm cov khoom, nws yuav cuam tshuam rau cov khoom sau, cov khoom nkag mus nrog rau qhov kov mos thiab suave ntawm daim tawv uas nws tuaj yeem muab tau.Tau kawg, qhov khoom kawg ntawm cov khoom polymer muaj feem cuam tshuam nrog ntau yam xws li polymerization, ntev ntawm cov saw, cov qauv tshuaj lom neeg, kev ua haujlwm, cov pab pawg hydrophilic, thiab lwm yam. Qhov hnyav molecular tsis tuaj yeem suav tias yog qhov siv tau ntawm cov khoom.
Qhov hnyav molecular ntawm feem ntau ntawm cov neeg sawv cev polymer retanning hauv khw yog nyob ib puag ncig 20000 txog 100000 g / mol, cov khoom ntawm cov khoom nrog qhov hnyav molecular hauv lub sijhawm no qhia tau tias muaj cov khoom sib npaug ntau dua.Txawm li cas los xij, qhov hnyav molecular ntawm ob qho ntawm Cov Khoom Txiav Txim Siab yog sab nraum lub sijhawm no hauv qhov kev taw qhia rov qab.

Tam sim no cia peb nrhiav seb dab tsi yog tom qab ntawm qhov daj ntawm tawv dawb——Xyoo 1911 AD, Dr. Stiasny tau tsim ib hom tannin tshiab uas hloov tau cov tannin los ntawm zaub. Piv rau cov tannin los ntawm zaub, cov tannin yooj yim tsim, muaj cov khoom zoo heev rau kev tanning, xim kaj thiab nkag tau zoo. Yog li ntawd, nws tau los ua ib qho tseem ceeb hauv kev lag luam tanning dhau ib puas xyoo ntawm kev txhim kho. Hauv cov thev naus laus zis niaj hnub no, hom tannin no siv rau hauv yuav luag txhua yam khoom.
Vim nws cov qauv sib txawv thiab daim ntawv thov, lawv feem ntau hu ua synthetic tannin, phenolic tannin, sulfonic tannin, disperse tannin, thiab lwm yam. Qhov sib xws ntawm cov tannins no yog tias lawv cov monomer feem ntau yog cov qauv tshuaj phenolic.

DESOATEN ARA Amphoteric Polymeric Tanning Agent thiab DESOATEN ARS Amphoteric Synthetic Tanning Agent | Cov Lus Qhia Zoo Tshaj Plaws ntawm Kev Txiav Txim Siab
Muaj ib tug cwj pwm hu ua Wang Yangming hauv The Ming Dynasty. Thaum nws tsis nyob hauv lub tuam tsev, nws tau tsim lub tsev kawm ntawv ntawm lub siab; thaum nws yog ib tug thawj coj ntawm niam txiv, nws tau pab cov zej zog; thaum lub teb chaws muaj teeb meem, nws siv nws txoj kev txawj ntse thiab kev ua siab loj los yuav luag ib leeg tua cov neeg tawm tsam thiab tiv thaiv lub teb chaws kom tsis txhob raug kev puas tsuaj los ntawm kev ua tsov rog hauv tebchaws. "Kev tsim kom muaj kev zoo thiab kev coj zoo thiab kev hais lus tsis yog qhov kev xaiv thib ob hauv tsib txhiab xyoo dhau los." Wang Yangming txoj kev txawj ntse zoo yog qhov tseeb tias nws ua siab zoo dua thaum ntsib cov neeg zoo thiab ntse dua thaum ntsib cov neeg tawm tsam ntse.
Lub ntiaj teb no tsis yog ib sab xwb, feem ntau nws yog hermaphroditic. Ib yam li cov neeg sawv cev tanning amphoteric ntawm cov tshuaj tawv. Cov neeg sawv cev tanning amphoteric yog cov neeg sawv cev tanning uas muaj pawg cationic thiab pawg anionic hauv tib lub qauv tshuaj - thaum pH ntawm lub kaw lus yog qhov isoelectric point ntawm tus neeg sawv cev tanning. tus neeg sawv cev tanning tsis muaj cov khoom cationic lossis anionic;
Thaum lub pH ntawm lub cev qis dua qhov isoelectric point, pawg anionic ntawm tus neeg sawv cev tanning raug tiv thaiv thiab xav tias muaj tus cwj pwm cationic, thiab rov ua dua. -
Ua kom tsab xov xwm floater sib npaug dua, DESOATEN ACS | Cov Lus Qhia Zoo Tshaj Plaws ntawm Kev Txiav Txim Siab
Yog tias koj tsav tsheb hauv Xinjiang, ua raws Lianhuo Expressway rov qab mus rau Urumqi, tom qab hla Guozigou Choj, koj yuav dhau los ntawm lub qhov av ntev, thiab lub sijhawm koj tawm hauv lub qhov av - lub xiav loj ntshiab yuav ntws rau hauv koj lub qhov muag.

Floater yog tej zaum cov qauv tawv uas qhia tau qhov zoo nkauj no zoo tshaj plaws.
Cov tawv nqaij uas muaj cov khoom siv floater yog ib hom tawv uas siv ntau vim nws muaj cov noob tshwj xeeb, ua rau nws zoo nkauj thiab xis nyob. Nws siv dav hauv cov khau yooj yim, cov khau sab nraum zoov thiab cov rooj tog zaum. Nws kuj siv los txhim kho cov qauv thiab ua kom cov tawv zoo nkauj dua, vim tias qhov tawg zais qhov puas tsuaj rau tawv.Tiam sis ib daim tawv zoo uas ntab dej kuj xav tau cov tawv rawhide qub heev. Nws xav tau kom daim tawv wetblue ntub sib npaug zoo, txwv tsis pub nws yuav ua rau muaj teeb meem tawg tsis sib npaug. Txawm li cas los xij, txawm tias daim tawv wetblue tau kho zoo los xij, qhov sib txawv ntawm cov tawv nqaij qub ntawm cov tsiaj, tshwj xeeb tshaj yog qhov sib txawv loj ntawm cov pob txha nraub qaum thiab sab plab, tuaj yeem ua rau tawg qhov teeb meem loj tshaj plaws ntawm cov tawv floater. Yog li ntawd, los teb rau qhov teeb meem no, pab pawg neeg txiav txim siab tau qhia txog kev daws teeb meem tshiab.
