Umuti wo gukaranga uruhu wa polymer ufite imikorere ya Ultra n'uburemere bwa molekile 'budasanzwe' | Icyemezo cyiza cyo gutanga umusaruro
uburemere bwa molekile y'ibicuruzwa bya polymer
Mu bijyanye n'imiti ikoreshwa mu ruhu, kimwe mu bibazo bihangayikishije cyane mu kiganiro ku bicuruzwa bya polymer ni uko, ikirere cy'uko ibicuruzwa ari ikintu gito cyangwa kinini.
Kubera ko mu bicuruzwa bya polymer, uburemere bwa molekile (mu by’ukuri, uburemere busanzwe bwa molekile. polymer igizwe n’ibice bito na binini bya molekile, bityo iyo uvuze uburemere bwa molekile, akenshi yerekeza ku buremere busanzwe bwa molekile.) ni kimwe mu bintu by’ingenzi bigize imiterere y’ibicuruzwa, bishobora kugira ingaruka ku buryo ibicuruzwa byuzuza, byinjira ndetse n’aho bikorera uruhu rworoshye kandi rurerure.Birumvikana ko imiterere ya nyuma y’umusaruro wa polimeri ifitanye isano n’ibintu bitandukanye nko kuyungurura, uburebure bw’umunyururu, imiterere ya chimique, imikorere, amatsinda akunda amazi, nibindi. Uburemere bwa molekile ntibushobora gufatwa nk'aho ari bwo bwonyine bugaragaza imiterere y’umusaruro.
Uburemere bwa molekile bw'ibintu byinshi bihindura imiterere ya polymer ku isoko buri hagati ya 20000 na 100000 g/mol, imiterere y'ibicuruzwa bifite uburemere bwa molekile muri iki gihe igaragaza imiterere iringaniye.Ariko, uburemere bwa molekile bw'ibicuruzwa bibiri bya Decision buri hanze y'iki gihe mu cyerekezo gitandukanye.

Ubushyuhe bw'urumuri bwiza cyane | Icyemezo cyiza cy'ibicuruzwa bya syntan gitangwa n'umwanzuro
Hari ibintu bisanzwe dusanga mu buzima bwacu bidutera kumwenyura igihe cyose tubitekerejeho. Nk’inkweto z’umweru nziza cyane zo mu kabati k’inkweto zawe.
Ariko, rimwe na rimwe birakubabaza kwibuka ko uko igihe kigenda gihita, inkweto ukunda ntizizongera kuba zera kandi zirabagirana, kandi zizagenda zisaza buhoro buhoro kandi zigasaza.
Noneho reka turebe icyari inyuma y'umuhondo w'uruhu rwera——Mu 1911 nyuma ya Yesu, Dr. Stiasny yavumbuye tannin nshya ya sintetike ishobora gusimbura tannin y'imboga. Ugereranyije na tannin y'imboga, tannin y'ubukorikori yoroshye kuyikora, ifite ubushobozi bwo kuyisiga, ibara ryoroheje kandi irabyinjiramo neza. Bityo yaje gufata umwanya ukomeye mu nganda zisiga tannin mu myaka ijana ishize. Mu ikoranabuhanga rigezweho ryo gusiga tannin, ubu bwoko bwa tannin y'ubukorikori bukoreshwa hafi mu bintu byose.
Bitewe n'imiterere n'ikoreshwa ryabyo bitandukanye, bikunze kwitwa tannin y'ubukorano, tannin ya phenolic, tannin ya sulfonic, tannin ikwirakwira, n'ibindi. Igisanzwe cy'izi tannins ni uko monomer yazo akenshi iba ifite imiterere ya phenolic chemical.

Imiterere myiza cyane yo gukaraba, komeza umugozi woroshye｜Icyemezo cy'umwanzuro w'ibicuruzwa byiza bya DESOPON SK70
Ifuro ni iki?
Ni ubumaji buri hejuru y'umukororombya;
Ni urumuri rwiza ku musatsi w'uwo dukunda;
Ni inzira zisigaye iyo dolphin yibira mu nyanja y'ubururu bwimbitse…Ku bakora akazi ko gushushanya, ifuro riterwa no kuvurwa mu buryo bwa mekanike (imbere mu ngoma cyangwa mu mapine), umwuka washyizwe mu gice cy’amazi akora mu byuma bisukura umwuka, bigahinduka uruvange rwa gaze n’amazi.
Ifuro ntirishobora kwirindwa mu gihe cyo gutosa. Ibyo biterwa nuko, mu gihe cyo gutosa, cyane cyane mu cyiciro cyo kongera gushonga, amazi, surfactants n'uburyo bwo kuvura imashini ari byo bintu bitatu by'ingenzi bituma ifuro ritera, nyamara ibi bintu bitatu bibaho hafi mu gihe cyose cyo gutosa.Muri ibyo bintu bitatu, surfactant ni kimwe mu bikoresho by'ingenzi bikoreshwa mu gihe cyo gukaraba. Gutoseza neza kw'igishishwa kimwe kandi gihoraho hamwe n'uburyo imiti yinjira mu gishishwa byose biterwa nabyo. Ariko, ingano nini ya surfactant ishobora gutera ibibazo by'ifuro. Ifuro ryinshi rishobora guteza ibibazo mu gihe cyo gukaraba. Urugero, bishobora kugira ingaruka ku buryo imiti yinjira neza, ikayikuramo, ndetse no kuyifata neza.

DESOATEN ARA Amphoteric Polymeric Tanning Agent na DESOATEN ARS Amphoteric Synthetic Tanning Agent | Ibyifuzo by'Icyemezo
Hari umuntu witwa Wang Yangming mu Ngoma ya Ming. Ubwo yari kure y'urusengero, yashinze ishuri ry'ubwenge; ubwo yari umukozi w'umubyeyi, yagiriraga akamaro umuryango; ubwo igihugu cyari kiri mu bihe bikomeye, yakoresheje ubwenge bwe n'ubutwari bwe kugira ngo ahagarike imyivumbagatanyo kandi akumire igihugu kwangirika n'intambara y'abenegihugu. “Gushyiraho imico myiza n'ubunyangamugayo n'imvugo ntabwo ari amahitamo ya kabiri mu myaka ibihumbi bitanu ishize.” Ubwenge bukomeye bwa Wang Yangming buri mu kuba yari umuntu mwiza imbere y'abantu beza kandi akaba umuhanga cyane imbere y'ibyigomeke by'abenegihugu.
Isi ntabwo ishingiye ku ruhande rumwe, akenshi iba ifite imiterere ya hermaphroditic. Kimwe n'ibintu bitera uruhu mu ruhu. Ibintu bitera uruhu mu ruhu ni ibintu bitera uruhu bifite itsinda rya cationic n'itsinda rya anionic mu miterere imwe ya shimi - iyo pH y'iyi sisitemu ari yo ngingo ya isoelectric y'ikintu gitera uruhu. Ikintu gitera uruhu ntikigaragaza imiterere ya cationic cyangwa anionic;
Iyo pH y'iyi sisitemu iri munsi y'ingingo ya isoelectric, itsinda rya anionic ry'ikintu gitanga uruhu rirakingirwa kandi rigafata imiterere ya cationic, naho ibinyuranye na byo. -
Komeza ushyireho ingingo ijyanye n'urusobe rw'inyandiko, DESOATEN ACS | Ibyifuzo by'Umwanzuro w'Icyemezo
Niba utwaye imodoka muri Xinjiang, kurikira Lianhuo Expressway usubire Urumqi, nyuma yo kwambuka ikiraro cya Guozigou, uzanyura mu mwobo muremure, kandi igihe uzaba uvuye mu mwobo - ibara ry'ubururu rinini ry'umweru rizagutera amaso.
Kuki dukunda ibiyaga? Wenda bitewe nuko ubuso bubengerana bw'ikiyaga buduha ituze 'rihoraho', ritameze nk'amazi yo mu iriba cyangwa rigahinduka nk'amazi y'amazi, ahubwo rituje kandi rirangwa n'ubuzima, hakurikijwe imiterere y'Iburasirazuba yo kwitonda no kwisuzuma.
Floater ishobora kuba ari yo ruhu rugaragaza neza iyi miterere.
Floater ni ubwoko busanzwe bw'uruhu kubera ko rufite ingaruka zidasanzwe, bigatuma uruhu rusa neza kandi rworoshye. Ikoreshwa cyane mu nkweto zisanzwe, inkweto zo hanze n'ibikoresho byo mu nzu. Ikoreshwa kandi mu kunoza imiterere no kunoza urwego rw'uruhu, kuko uruhu rucika ruhisha ibyangiritse ku ruhu.Ariko icyuma cyiza cyo mu mazi gisaba cyane uruhu rwa mbere. Gisaba ko uruhu rwo mu mazi rungana neza, bitabaye ibyo gishobora guteza ibibazo byoroshye byo kwangirika. Ariko, nubwo uruhu rwo mu mazi rwavuwe neza, itandukaniro ry’uruhu rw’umwimerere rw’inyamaswa, cyane cyane itandukaniro rinini mu mugongo no mu nda zo ku ruhande, rishobora gutuma uruhu rwo mu mazi rurushaho kuba ikibazo gikomeye. Rero mu gusubiza iki kibazo, itsinda rya Decision ryashyizeho igisubizo gishya.

Ifu yoroshye cyane ya sintetike DESOPON USF | Ibyifuzo by'Icyemezo cya Premium
Ubworoherane
Mu misozi ya Ekwateri hamera ubwatsi bwitwa toquilla, amashami yabwo ashobora kubohwamo ingofero nyuma yo kuvurwa. Iyi ngofero yakunzwe cyane n'abakozi bo ku muyoboro wa Panama kuko yari yoroshye, yoroshye kandi ihumeka, kandi izwi nka "ingofero ya Panama". Ushobora kuzingira byose hejuru, ukabishyira mu mpeta hanyuma ukabyikuramo nta minkanyari. Bityo rero akenshi bipfunyikwa mu cyuma kandi bikazunguruka iyo bitambaye, bigatuma byoroha kuyitwara.
Kimwe mu bishushanyo bya Bernini bizwi cyane ni "Pluto Snatching Persephone", aho Bernini yaremye icyari "marble yoroshye" kurusha ibindi byose mu mateka y'abantu, agaragaza ubwiza buhebuje bwa marble mu "bworoshye" bwayo.
Ubworoherane ni bwo buryo bw'ibanze butuma abantu bumva ko ari bo. Abantu bakunda ubworoherane, wenda kubera ko butaduteza ibyago cyangwa ngo budutere akaga, ahubwo butuma tugira umutekano n'ihumure gusa. Iyo sofa zose zo mu ngo z'Abanyamerika ziba ari ubwiza bw'ibiti bikomeye byo mu Bushinwa, ntabwo hagomba kuba hari sofa nyinshi nk'izi, si byo se?
Kubwibyo, ku ruhu, ubwoya bwagiye buhora ari kimwe mu bintu bizwi cyane n'abaguzi. Byaba imyenda, ibikoresho byo mu nzu, cyangwa intebe.
Igikoresho cyiza cyane mu koroshya uruhu ni fatliquor.
Uburyo uruhu rworoshye ni bwo butuma rudakomeza kuba ruto, ahubwo ni ukurinda ko insinga zongera gufunga mu gihe cyo kumisha (kubura amazi mu mubiri).
Ariko uko byagenda kose, gukoresha fatliquors, cyane cyane zimwe na zimwe zisanzwe, bishobora gutuma uruhu rworoshye cyane kandi rworoshye. Ariko kandi, hari n'ibibazo: fatliquors nyinshi zisanzwe zifite impumuro mbi cyangwa umuhondo bitewe n'umubare munini w'imigozi idafunze mu miterere yazo. Fatliquors za synthetic, ku rundi ruhande, ntizihura n'iki kibazo, ariko akenshi ntizoroshye kandi ntiziruhura nkuko bisabwa.Icyemezo gifite umusaruro umwe ukemura iki kibazo kandi ukagera ku musaruro udasanzwe:
