hordhac kooban oo badeecad ah

Diacetone acrylamide oo leh laba kooxood oo falgal ah: N - amides-ka la beddelay iyo ketone, ethylene iyo monomer copolymerization oo leh kuwo kale oo aad u fudud, sidaas darteed ketone carbonyl, oo lagu soo bandhigay polymer-ka, isticmaalka sifooyinka kiimikada ee ketone carbonyl, waxay samayn kartaa laamaha polymer/isku-xidhka sida falcelinta, waxaa loo isticmaalay in lagu diyaariyo dhejisyo kala duwan, dhumuc-dhejin, wakiilka xoojinta warqadda, wakiilka isku-xidhka, iwm. Waxaa si weyn loogu isticmaalay dahaarka, dhejiska, warshadaha kiimikada maalinlaha ah, wakiilka daaweynta resin epoxy, kaaliyaha resin sawir-qaadista, kaaliyaha dharka, caafimaadka iyo caafimaadka iyo meelaha kale.

sifo

1. Barta iftiiminta >110 °C
2, dhibic dhalaalaysa 57 ~ 58 °C
3, dhibic karkaraya 120℃ (1.07 kPa), 93 ~ 100℃ (13.33 ~ 40.0 Pa)
4. Cufnaanta qaraabada ah 0.998 (60 °C)
5, kiristaal cad ama huruud yar, midab la'aan ka dib marka uu dhalaalo.
6, oo ku milma biyaha, methanol, chloromethane, benzene, acetonitrile, ethanol, acetone, tetrahydrofuran, ethyl acetate, styrene, n-hexanol iyo dareere kale oo dabiici ah, oo aan ku milmi karin batroolka ether (30 ~ 60 °C).

isticmaal

Badanaa waxaa loogu yeeraa diamine,N-(1,1-dimethyl-3-oxobutyl) ka dibna DAAM. Adeegsiga DAAM waa sidan soo socota:
⑴ Codsiga rinjiga timaha
Astaamaha muhiimka ah ee diamine waa in homopolymer-keeda ama copolymer-kiisu aanu ku milmi karin biyaha, laakiin uu leeyahay "neefsasho biyo", heerka nuugista biyaha ilaa 20% ~ 30% miisaankiisa, marka qoyaanka deegaanku uu ka yar yahay 60%, laakiin sidoo kale uu sii dayn karo biyaha. Astaantan waxaa loo isticmaalaa in lagu soo saaro buufinta timaha iyo resin-ka sawir-qaadista leh ee diamine.
⑵ Codsiga resin sawir-qaadis ah
Isticmaalka BRIGHT, HARD iyo ACID-base DIAMIN homoPOLYMER SI AAD U SOO SAARTO RIIXINTA SAWIRKA LEH waxay ka dhigi kartaa resin-ka mid xasaasi u ah sawir-qaadista si dhakhso ah, si fudud looga saari karo qaybta aan sawirka lahayn ka dib soo-gaadhista, si loo helo sawir cad iyo xoog wanaagsan, dareere iyo saxan iska caabbinta biyaha.
Isticmaalka kale ee muhiimka ah ee diamines waa in qayb ahaan lagu beddelo gelatin. Gelatin waxaa loo isticmaalaa sidii emulsion sawir-qaadis ah, kaas oo ka faa'iidaysta ku dhawaad ​​​​dhammaan sifooyinka gaarka ah ee gelatin, sidaa darteed way adkayd in la helo badeecad ku habboon oo lagu beddelo in ka badan 100 sano. Gelatin sawir-qaadis oo saafi ah ayaa ku yaraan doonta Shiinaha muddo dheer, waxaa la filayaa in agabka sawir-qaadista gudaha ay u baahan yihiin gelatin qiyaastii 2500t, laakiin hadda soo saarista gelatin sawir-qaadis gudaha ah waa boqolaal tan oo keliya.
(3) diyaarinta saxanka daabacaadda ee balaastikada ah ee gargaarka degdegga ah
(4) Ku dhejinta dhejiska
Waxaa loo isticmaali karaa sidii kor u qaadis iyo hagaajin isku-xidhka isku-dhafka fiilooyinka, sibidhka, galaaska, aluminiumka iyo polyvinyl chloride. Waxa kale oo loo samayn karaa dhejisyo xasaasi u ah cadaadiska. Waxa kale oo loo isticmaali karaa dhejisyo xasaasiyad ku leh kulaylka warqadda, dharka iyo filimada balaastikada ah ee ay ku jiraan polymers-ka acrylic.
⑸ Adeegsiga ⑸ dhinacyo kale
Marka laga soo tago dhinacyada kor ku xusan ee codsiga, diacetone acrylamide ee meelaha kale ayaa sidoo kale si ballaaran loo isticmaali karaa:
① waxaa loo isticmaali karaa sidii wakiilka daaweynta ee cusbi epoxy, rinjiga ka hortagga miridhku, rinjiga biyaha hoostooda hoostiisa mara ee markabka, rinjiga resin acrylic, polyester aan dheregsanayn iyo dahaadh kale;
② Monomer-ka copolymer-ka ee diacetone acrylamide ee biyaha ku milma ayaa si wax ku ool ah loogu isticmaalay caddeynta adkaha la hakiyey;
③ waxaa loo isticmaali karaa sida qalabka duubista laysarka kulaylka;
④ Waxaa loo isticmaalaa sidii wakiil ka hortagga dhalaalka galaaska;
⑤ lagu dabaqay agabyada nuqulka azo;
⑥ Waxaa loo isticmaalaa qaybo ka mid ah resin-ka sawir-qaadista leh ee biyaha ku milma.

xirmada iyo gaadiidka

B. Badeecadan waxaa loo isticmaali karaa, 25KG, BACO
C. Ku kaydi meel qabow, qalalan oo hawo leh gudaha. Weelasha waa in si adag loo xidhaa ka dib isticmaal kasta ka hor inta aan la isticmaalin.
D. Badeecadan waa in si fiican loo xiraa inta lagu jiro rarista si looga hortago qoyaanka, alkali iyo aashitada xooggan, roobka iyo wasakhda kale ee isku dhafan.
