Kaaliyaha sameynta filimka dahaarka leh Alcohol Ester-12 CAS 25265-77-4 Wakiilka isku-darka Texanol
Khamriga Ester-12 (2,2,4-Trimethyl-1,3-pentanediol 1-monoisobutyrate) waa wakiil isku-dhaf ah oo waxtar sare leh oo loogu talagalay rinjiga ku salaysan biyaha, oo aan loo kala saarin VOC sida waafaqsan xeerarka Yurub iyo Shiinaha.
Xasillooni hydrolytic oo aad u fiican, oo la jaan qaadi karta noocyo kala duwan oo emulsions ah waxaa ku jira acrylicemulsion PH sare leh
Waxaa si fudud u nuugi doona walxaha emulsion-ka marka si fudud loogu daro, si looga faa'iidaysto isku-darka walxaha. Hagaajinta dareeraha rinjiga iyo qoynta midabka.
Astaamaha Muhiimka ah ee Khamriga Ester-12 sida soo socota:
1. La jaan qaadaya emulsions kala duwan oo ay ku jiraan emulsion-ka acrylic-ga sare ee PH
2. Xasillooni hydrolytic oo aad u fiican
3. Hagaaji dareeraha rinjiga iyo qoynta midabka
4. Hagaaji adkaanta filimka iyo iska caabbinta xoqidda
Waa walxo sameeya filimada si wax ku ool ah loogu isticmaali karo vinyl acetate homopolymers iyo copolymers iyo terpolymers latex, iyo acrylic, styrene iyo vinyl, vinyl acetate latex. Marka loo isticmaalo rinjiga latex iyo dahaarka, waxay leedahay iswaafajin wanaagsan oo resin ah.
Iyada oo ah nooc cusub oo ah wakiilka sameynta rinjiga latex, Alcohol Ester-12 waa mid ammaan ah, hufan oo lagu dabaqi karo dhammaan noocyada resin-ka synthetic-ga.
Faa'iidooyinka Alcohol Ester-12 ee loo isticmaalo rinjiga latex waa: xoog isku-dhafan oo wanaagsan heerkulka hooseeya, xasillooni dheellitiran oo wanaagsan, xasillooni midab oo wanaagsan; iyo in la hagaajiyo isticmaalka rinjiga, sida iska caabbinta cimilada, helitaanka rinjiga iyo nadiifinta, awoodda dayactirka iyo awoodda sameynta midabka.
