Selelekela sa Diactone Acrymide

Diactone acrymide (Daam) ke motsoako oa manyolo o sebelisoang ka bongata likopanong tsa indasteri, haholo-holo tlhahisong ea thepa e fapaneng ea polymer e thehiloeng polymer. Ke moqapi ea sebetsang ea Acrymide, e nang le Sehlopha sa Acrymeide le lihlopha tse peli tsa Acestone tse fanang ka thepa e ikhethang ea 'mele le lik'hemik'hale ho molek'hule. Dame o hlokometse ka lebaka la maemo a eona a fetolang sebopeho sa polymer, a susumetsa thepa ea bona ea ho etsa litokollo le botsitso.

Motsoako ona o thahasella ka ho khetheha mangolong a thepa e tsoetseng pele, boholo ba likhomo, likhakanyo le li-hydrogels. Sebopeho sa eona sa lik'hemik'hale le boitšoaro se etsa hore e be mahareng a ho bōpeloa ha basebetsi ka thepa e fapaneng, ho kenyelletsa boenjiniere ba biodity, temo ea metsi.

Joale, re tla hlahloba sebopeho sa lik'hemik'hale sa diactone acertheside, ho sebelisa li-syntheside, ho sebelisa le lits'ebetso tsa eona, hammoho le tšusumetso ea eona ea tikoloho le ea polokeho.

Sebopeho

Diactone acrymide (c₇h₁₁no₂) e na le sebopeho se ikhethang se e khethollang ho acterlaros tse ling. Ke monommer e nang le lihlopha tse peli tsa tšebetso tse peli tsa tšebetso:

1. Sehlopha sa Acrylamide (-ch = CHELEC (O) NH): Sehlopha sa Acrylamide ke karolo e hlalosang molek'hule. Sehlopha sena se lumellana haholo ka lebaka la ho hlonama pakeng tsa khabone ea khabone le sehlopha se haufi le Carbonyl, ho etsa hore komporo e be boikarabelo ba polymeria.
2. Lihlopha tsa Acestone (-c (Ch₃) ₂o): Lihlopha tse peli tsa Acestone li hokahane le atom ea naetrojene ea acrymide. Lihlopha tsena li fana ka tšitiso ea Sterike ho potoloha sebaka sa polymerizing, se ama Dam ha ho bapisoa le litloholo tse ling tsa Acrylamide.

Lihlopha tsa Acestone ho Daam Thusa ho fetola linyemele, le ho ingolisa. Kotsi e tloaetse ho lekola, metsi a se nang 'mala oa mocheso ka kamoreng ea kamore,' me alo ea eona ka metsing e leka-lekana. Leha ho le joalo, Daam e qhibilihisa li-solvent tsa manyolo, ho kenyeletsoa li-geld le acetophols, e leng ea bohlokoa lits'ebetsong tse ngata tsa indasteri moo solvents e sebelisoang e le mecha ea litaba.

Likopo tsa Diactone Acrymide

Litšoantšiso tsa lefu la tsoekere li bapala karolo ea bohlokoa lits'ebetsong tse fapaneng tsa indasteri, ka lebaka la bokhoni ba eona ba ho theha sethepu se nang le thepa e fetotsoeng. Ka tlase ho na le tse ling tsa libaka tsa bohlokoa tseo daame li sebelisoang hangata:

1. Polymerication le copolymeriation

Daam e sebelisoa haholo joalo ka monomer ka li-synttheis tsali-copolelymers. Ha o na le borikhoe, Daam e etsa mekhatlo e hokahaneng e amanang le ho hlahisaLi-sulymers tsa SupebrabledBones (saps), li-hydrogel le thepa e 'ngoe e tsoetseng pele ea Polymer. Ho ba teng ha lihlopha tse peli tsa linaleli tse peli ho Daam ho fana ka thepa e ikhethileng, joalo ka hydrophobicity, e ntlafatsang botsitso ba mollo, mme ba ntlafatsa limakasine tsa mollo.

Hangata li-polymers tsena li sebelisoa likopo tse kang:

• Phekolo ea Metsi: Li-polymers tse thehiloeng ho daam li sebelisetsoa ho etsa li-flocculants le li monya bakeng sa lits'ebetso tsa ho hloekisa metsi.
• Likopo tsa Temo: Li-polymers li hlahisoa le Daam li sebelisoa li-manyolo a lokolohileng tsa ho lokolloa le li-conditioners tsa mobu.
• Likopo tsa biomedical: Damam-ntsopa-holo ea lihloliloeng tsa bo-ralitima-mafu tse ngata li sebelisetsoa lisepa tsa lithethefatsi tse laoloang le liaparo tse leqeba ka lebaka la phepelo ea tsona ea biocondomatic.

2. Lits'enyehelo le li-Coatis

Ts'ebeliso ea diactotoe acrrymide ka lidolara le makhapetla a atileng, haholo-holo indastering tse hlokang matla a phahameng le ho tšoarella. Ha balommers ba bang, Daam o kenya letsoho ho thehoa ha lifilimi tse thata, tse hanyetsanang le tse thibeloang ho senya tikoloho. Sena se etsa hore motho ea nang le polymer a tšoanelehe:

• Likotsi tsa Tsamaiso: Li-cartats tse thehiloeng Dam li ka sebelisoa ka tšepe, polasetiki, le masene a ho ntlafatsa ho tšoarella le ho hanela khatello ea tikoloho.
• Marang-rang a Acrylic: Bohloko ba Daam bo teng ka pel'a bakuli ba bang ba masome ba ka tlamaha ka likarolo tse fapaneng, ba li etsa barekisi, kaho le likoloi tsa likoloi.

3. Hydrogels

Daam e bohlokoa ka ho khetheha ho pōpong eahydrogels, eo e leng marang-rang a likarolo tse tharo tsa polymis tse ka amohelang metsi a mangata. Li-hydrogel tsena li sebelisoa masimong a fapaneng, ho kenyelletsa:

• Likopo tsa biomedical: Liekhilo tse entsoeng ho tloha Daam li sebelisoa lits'ebetsong tsa ho tlisa liphallelo, pholiso ea maqeba, boenjiniere ba lisele, le ha ho tšoloha ho hola holo ea sele.
• Temo: Li hydrogel li ka sebelisoa ho ntlafatsa ho boloka metsi mobung, haholo-holo libakeng tse opolotsoeng.

4. Li-sulymers tsa SupebrabledBones (saps)

E 'ngoe ea likopo tse sa tsebehaleng ka ho fetisisa tsa diactone acrylamide li hlahisoa keLi-polymers tsa Superabseddleben, e ka monyang le metsi a mangata kapa maro a metsi a halefileng a amana le boima ba bona. Lisebelisoa tsena li tšoaea liphoso lihlahisoa tse kang lipeo, lihlahisoa tsa bohloeki le lihlahisoa tsa batho ba baholo.

Matla a mangata a nang le pherekano a nang le pherekano e thehiloeng ho superabent e hlahisoa ke bokhoni ba Daam ho theha marang-rang a hokahanyang haholo ho tšoasa limolek'hule tsa metsi.

Mehopolo ea tikoloho le ea polokeho

Ha destone a acrrymide a na le lits'ebetso tse fapaneng tsa indasteri, tšusumetso ea eona ea tikoloho le boemo ba polokeho ea tikoloho le boemo ba polokeho e lokela ho hlokomeloa ka hloko.

1. Chefo

Joalo ka lik'hemik'hale tse ngata tsa tlhaho, Dame e ka kotsi haeba e sa sebelisoe hantle. Ho pepesehela meaho e phahameng ea li-mouoane kapa ho ikopanya le letlalo ho ka baka ho teneha. Ho bohlokoa ho sebelisa lisebelisoa tse sireletsehileng tsa ts'ireletso, tse kang liatlana le li-gloves, ha u sebetsana le Dam sebakeng sa indasteri kapa la laboratori.

Khalefo kapa ho kenella ha Daam ho ka ba kotsi. Ho bohlokoa ho latela litataiso tsa polokeho le litekanyetso tsa taolo tsa polokeho ho fokotsa kotsi ea ho pepesetsoa.

2. Tšireloana ea tikoloho

Ka lebaka la tšebeliso e ntseng e eketseha ea li-polymers tse ntseng li eketseha litsing tse fapaneng tsa lits'ebetsong tse fapaneng, ho na le ho tšoenyeha ka ho phehella le ho holofala ha lisebelisoa tsena. Polymers e tsoa ho Daam ho se ke ea nyenyefatsa tikoloho ka seng tikoloho, e tlatsetsa tšilafalo ea polasetiki haeba e sa senyehe hantle. Ka hona, bafuputsi ba ntse ba hlahloba mekhoa e mafolofolo ea ho ntlafatsa litlolo tse tsamaisoang hantle ha likheo tsa Dama le ho nts'etsapele mefuta e meng e ntšetsang.

3. Litšila tsa ho lahla

Ho lokela ho lateloa mekhoa e nepahetseng ea ho fokotsa ho thibela tšilafalo ea tikoloho. Dam, joalo ka lik'hemik'hale tse ngata, ha lia lokela ho lokolloa mehloling ea metsi kapa metseng ea mekato e se nang kalafo. Ho sebelisa mekhoa ea ho nchafatsa le ho tsamaisa taolo ea litšila ho ka thusa tšusumetso ea tikoloho.

Diactostoide Acrymide ke setsi sa bohlokoa tšimong ea boenjiniere ba polytmer le boitsebiso ba lintho tse bonahalang. Sebopeho sa eona se ikhethang se e thusa hore e sebelisoe lits'ebelisong tse fapaneng, ho tsoa polymers ea Supebrabes ho ea likhato, bosholu le li-hydrogels. Bokhoni ba ho laola tsela ea eona le ho fetola thepa ea eona e etsang hore e be matla a feto-fetohang bakeng sa lits'ebetso tsa indasteri.

Leha ho bile le melemo e mengata, tšebeliso ea Daame e lokela ho a khona ho eketsa phello ea eona ea tikoloho le chefo. Ho tsoela pele ka lipatlisiso ho qobella polyers e matla le ho feta ea biodegrada ho bohlokoa bakeng sa bokamoso ba Dame mosebetsing oa indasteri.

Ha lisebelisoa tsa ho eketseha li ntse li tsoela pele haholoanyane, tse sebetsang li lebelletsoe hore li lule li le maemong a bohlokoa a mahlale a mangata, kalafo ea metsi le temo ea metsi le temo.
