Cov khoom qhia luv luv

Diacetone acrylamide nrog ob pawg reactive: N - hloov amides thiab ketone, ethylene thiab monomer copolymerization nrog rau lwm yam yooj yim heev, yog li ketone carbonyl, nkag mus rau hauv lub polymer, kev siv cov ketone carbonyl tshuaj muaj zog, tuaj yeem ua rau cov polymer / koom nrog cov ceg xws li cov tshuaj tiv thaiv. , yog siv los npaj ntau yam adhesives, thickener, ntawv reinforcing tus neeg saib xyuas, crosslinking tus neeg saib xyuas, thiab lwm yam. Nws tau dav siv nyob rau hauv txheej, nplaum, kev lag luam tshuaj niaj hnub, epoxy resin curing agent, photosensitive resin auxiliary, textile auxiliary, kev kho mob thiab kev noj qab haus huv thiab lwm yam. teb.

6, soluble hauv dej, methanol, chloromethane, benzene, acetonitrile, ethanol, acetone, tetrahydrofuran, ethyl acetate, styrene, n-hexanol thiab lwm yam organic solvents, insoluble hauv roj av ether (30 ~ 60 ° C).

siv

Nws feem ntau hu ua diamine, N-(1,1-dimethyl-3-oxobutyl) thiab tom qab ntawd DAAM.Daim ntawv thov ntawm DAAM yog raws li nram no:
⑴ Daim ntawv thov hauv cov plaub hau primer
Cov yam ntxwv tseem ceeb ntawm diamine yog tias nws homopolymer lossis copolymer yog insoluble hauv dej, tab sis muaj "dej ua pa", tus nqi nqus dej mus txog 20% ​​~ 30% ntawm nws qhov hnyav, thaum huab cua noo tsawg dua 60%, tab sis kuj tuaj yeem ua tau. tso dej.Qhov no feature yog siv los tsim cov plaub hau tsuag fixative thiab photosensitive resin nrog diamine.
⑵ Daim ntawv thov nyob rau hauv photosensitive resin
Siv BRIGHT, HARD thiab ACID-base RESISTANT SOLID DIAMine homOPOLYMER los tsim PHOTOSENSITIVE resin tuaj yeem ua rau cov resin photosensitive sai, yooj yim tshem tawm cov duab tsis zoo tom qab raug, kom tau txais cov duab meej thiab lub zog zoo, hnyav thiab dej tsis kam phaj .
Lwm qhov tseem ceeb ntawm kev siv diamines yog los hloov cov gelatin ib nrab.Gelatin yog siv los ua photosensitive emulsion, uas yuav siv sij hawm kom zoo dua ntawm yuav luag tag nrho cov khoom tshwj xeeb ntawm gelatin, yog li nws tau nyuaj rau nrhiav tau ib qho khoom zoo tagnrho los hloov nws rau ntau tshaj 100 xyoo.High purity photographic gelatin yuav nyob rau hauv luv luv nyob rau hauv Tuam Tshoj rau ib ntev lub sij hawm, nws yuav tsum tau hais tias lub domestic photosensitive cov ntaub ntawv yuav tsum tau gelatin txog 2500t, tab sis tam sim no lub zus tau tej cov domestic photographic gelatin tsuas yog ntau pua tons.
(3) rau kev npaj cov yas nyem luam ntawv phaj
(4) Daim ntawv thov hauv nplaum
Nws tuaj yeem siv los ua cov khoom lag luam thiab txhim kho cov fiber ntau, cement, iav, txhuas thiab polyvinyl chloride.Nws tseem tuaj yeem ua rau cov nplaum nplaum nplaum.Nws kuj tseem siv tau los ua cov nplaum nplaum rau cov ntawv, textiles thiab yas zaj duab xis uas muaj acrylic polymers.
⑸ Kev siv ⑸ hauv lwm yam
Ntxiv rau qhov saum toj no ob peb yam ntawm daim ntawv thov, diacetone acrylamide hauv lwm qhov chaw kuj tseem siv tau dav:
① tuaj yeem siv los ua tus neeg sawv cev kho rau epoxy resin, nkoj hauv qab cov xim pleev xim, nkoj hauv qab dej pleev xim, acrylic resin xim, tsis muaj polyester thiab lwm yam txheej;
② Cov dej-soluble copolymer monomer ntawm diacetone acrylamide tau siv tau zoo rau kev qhia meej ntawm cov khib nyiab pov tseg;
③ tuaj yeem siv los ua cov ntaub ntawv thermal laser;
④ Siv los ua iav los tiv thaiv qhov muag plooj;
⑤ siv rau hauv cov ntaub ntawv luam azo;
⑥ Siv ua dej-soluble photosensitive resin Cheebtsam.

pob thiab thauj

B. Cov khoom no tuaj yeem siv tau, 25KG, hnab
C. Khaws ntim rau hauv qhov chaw txias, qhuav thiab qhov cua nyob hauv tsev.Cov thawv ntim khoom yuav tsum tau muab kaw kom nruj tom qab siv txhua zaus ua ntej siv.
D. Cov khoom no yuav tsum raug kaw kom zoo thaum lub sijhawm thauj mus los kom tsis txhob ya raws, muaj zog alkali thiab acid, nag thiab lwm yam impurities los ntawm kev sib xyaw.
