kev taw qhia luv luv ntawm cov khoom
Diacetone acrylamide nrog ob pawg reactive: N - hloov amides thiab ketone, ethylene thiab monomer copolymerization nrog lwm yam yooj yim heev, yog li ketone carbonyl, qhia rau hauv polymer, kev siv cov khoom siv tshuaj lom neeg ketone carbonyl, tuaj yeem ua rau cov polymer / koom nrog cov ceg xws li kev ua haujlwm, tau siv los npaj ntau yam nplaum, thickener, ntawv txhawb nqa tus neeg sawv cev, crosslinking tus neeg sawv cev, thiab lwm yam. Nws tau siv dav hauv txheej, nplaum, kev lag luam tshuaj txhua hnub, epoxy resin curing tus neeg sawv cev, photosensitive resin auxiliary, textile auxiliary, kev kho mob thiab kev noj qab haus huv thiab lwm yam teb.
yam ntxwv
1. Qhov kub hnyiab >110 °C
2, qhov chaw yaj 57 ~ 58 ° C
3, qhov kub npau npau 120 ℃ (1.07 kPa), 93 ~ 100 ℃ (13.33 ~ 40.0 Pa)
4. Qhov ceev sib piv 0.998 (60 ° C)
5, dawb los yog me ntsis daj flake siv lead ua, tsis muaj xim tom qab yaj.
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
Feem ntau nws 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
Tus yam ntxwv tseem ceeb ntawm diamine yog tias nws cov homopolymer lossis copolymer tsis yaj hauv dej, tab sis muaj "kev ua pa dej", tus nqi nqus dej txog li 20% ~ 30% ntawm nws qhov hnyav, thaum qhov av noo tsawg dua 60%, tab sis kuj tuaj yeem tso dej tawm. Qhov no yog siv los tsim cov tshuaj tsuag plaub hau thiab cov tshuaj pleev xim nrog diamine.
⑵ Daim ntawv thov hauv cov khoom siv photosensitive
Siv BRIGHT, HARD thiab ACID-base RESISTANT SOLID DIAMine homOPOLYMER LOS TSIM COV PHOTOSENSITIVE resin tuaj yeem ua rau cov resin photosensitive sai, yooj yim tshem tawm cov khoom tsis yog duab tom qab raug, yog li kom tau txais cov duab meej thiab lub zog zoo, cov kuab tshuaj thiab cov phaj tiv thaiv dej.
Lwm qhov tseem ceeb ntawm kev siv diamines yog los hloov ib feem ntawm gelatin. Gelatin yog siv ua cov emulsion photosensitive, uas siv qhov zoo ntawm yuav luag txhua yam khoom tshwj xeeb ntawm gelatin, yog li nws tau nyuaj rau nrhiav cov khoom zoo tagnrho los hloov nws rau ntau tshaj 100 xyoo. Cov gelatin photographic purity siab yuav tsis muaj ntau hauv Suav teb ntev, nws xav tias cov ntaub ntawv photosensitive hauv tsev xav tau gelatin txog 2500t, tab sis tam sim no kev tsim cov gelatin photographic hauv tsev tsuas yog ntau pua tons.
(3) rau kev npaj cov yas luam ntawv phaj
(4) Daim ntawv thov hauv cov nplaum
Nws siv tau ua ib yam khoom siv los txhim kho thiab txhim kho cov khoom sib txuas rau cov fibrous compounds, cement, iav, txhuas thiab polyvinyl chloride. Nws kuj tseem siv tau ua cov nplaum uas rhiab heev rau siab. Nws kuj siv tau ua cov nplaum rhiab heev rau cua sov rau ntawv, ntaub thiab yas zaj duab xis uas muaj acrylic polymers.
⑸ Kev siv ⑸ rau lwm yam
Ntxiv rau ntau yam saum toj no ntawm daim ntawv thov, diacetone acrylamide hauv lwm qhov chaw kuj tuaj yeem siv dav:
① siv tau ua tus neeg sawv cev rau epoxy resin, xim tiv thaiv xeb hauv qab nkoj, xim hauv qab dej hauv qab nkoj, xim acrylic resin, polyester tsis muaj roj thiab lwm yam txheej txheem;
② Cov dej-soluble copolymer monomer ntawm diacetone acrylamide tau siv zoo rau kev ua kom pom tseeb ntawm cov khoom khov kho;
③ siv tau ua cov ntaub ntawv thermal laser;
④ Siv ua tus neeg sawv cev tiv thaiv kev ua kom tsis pom kev zoo;
⑤ siv rau hauv cov ntaub ntawv azo luam;
⑥ Siv ua cov khoom siv photosensitive resin uas yaj tau hauv dej.
pob khoom thiab kev thauj mus los
B. Cov khoom no siv tau, 25KG, hnab
C. Khaws cia rau hauv qhov chaw txias, qhuav thiab muaj cua nkag hauv tsev. Yuav tsum kaw cov thawv kom nruj tom qab siv txhua zaus ua ntej siv.
D. Cov khoom no yuav tsum tau kaw zoo thaum lub sijhawm thauj mus los kom tiv thaiv cov dej noo, alkali thiab acid muaj zog, nag thiab lwm yam tsis huv los ntawm kev sib tov.
