Waxa kale oo loo yaqaan propylene glycol diethanoate, 1,2-propylene glycol diethanoate ama PGDA (Propylene Glycol Diacetate). Halkan waxaa ah faahfaahinta muhiimka ah:

Guryaha jireed: dareere hufan oo huruud ah oo aan midab lahayn ama cirro leh, dhibic dhalaalaysa -31°C, barta karkarinta ku dhawaad ​​186-191°C, cufnaanta ilaa 1.05 g/ml (25°C), dhibic toosh 84.3-187°F. Waxay ku milmaysaa dareerayaasha organic waxayna wax yar ku milmi kartaa biyaha (76g/L at 20°C).

Codsiga alaabta

Propylene glycol diacetic acid ester (PGDA) waa isku dhis dabiici ah oo badan, inta badan loo isticmaalo sida dareere, balaastiig iyo emulsifier. Waxa si weyn loogu dabaqaa warshado kala duwan sida dahaarka, khadadka, dawooyinka, waxyaalaha la isku qurxiyo iyo cuntada.

1. In dahaarka iyo warshadaha khadadka: Sida dareere wax ku ool ah, waxa ay bedeli kartaa xalalka sare-VOC dhaqameed (sida toluene, butyl acetate, isophorone, cyclohexanone, iwm), milaan acrylic, polyurethane, epoxy iyo resins kale, hoos u viscosity ee nidaamka, iyo hagaajinaysaa dhalaalka iyo adkaanta; sida dareeraha daabacaadda khadadka iyo dahaarka fluorescent, waxay wanaajisaa sinnaanta iyo dhalaalka, gaar ahaan ku habboon rinjiga cad si looga hortago in la caddeeyo filimka rinjiga; sida gargaarka filim-samaynta, waxay hoos u dhigi kartaa heerkulka ugu yar ee samaynta filimka ee daahan waxayna ka hortagtaa in lagu caddeeyo filimka rinjiga ee jawiga qoyan, iyo sida wakiilka siman, waxay ka fogaan kartaa midabka sabaynta iyo ubaxa, samaynta lebis iyo dahaar siman.

2. Xabagyada iyo nadiifiyeyaasha: Xabagta, waxay u adeegtaa sidii dareere si ay u kordhiso xoogga isku xidhka iyo caabbinta cimilada, isla markaana, adoo hagaajinaya heerka uumiga, wanaajiso wakhtiga daaweynta; loo isticmaalo walxaha nadiifinta iyo rinji-saarayaasha, waxay si dhakhso ah u milmi kartaa saliidaha, wasakhda iyo filimada rinjiga ee duugga ah.

3. Sida wax lagu daro maadada-molecular-sare: Sida wakiilka ester-ka dabiiciga ah ee loogu talagalay shubista resins iyo caagagga cellulose acetic acid, waxay kor u qaadaysaa dabacsanaanta walxaha; warshadaha poliurethane, waxay u adeegtaa sida dareere loogu talagalay wakiilada daaweynta PU-ku salaysan, hagaajinta jilicsanaanta iyo hydrophobicity ee filimka rinjiga.

4. Goobaha dawooyinka iyo kuwa la isku qurxiyo: Wax soo saarka dawooyinka, waxa loo isticmaalaa sidii emulsifier, wakiilka qoynta, solubilizer iyo wakiilka dhiirrigelinta transdermal, oo loo isticmaalo emulsions, kiriimyada, irbadaha, wakiilada faashad, iwm.; warshadaha qurxinta, waxaa loo isticmaalaa in lagu soo saaro kareem, shaambo, iwm.

4. Warshadaha cuntada: Inta badan waxaa loo isticmaalaa sida dareere iyo milmiye si loogu diyaariyo nuxurka la cuni karo, una adeegaya sidii side si ay si siman u kala firdhiso una sii deyso qaybaha udgoonka.

Xaaladda kaydinta

Propylene glycol diacrylate waa in lagu kaydiyaa bakhaar gaar ah oo qabow, engegan, oo hawo fiican leh. Heerkulku waa inuusan dhaafin 30 ° C. Waa in laga ilaaliyaa iftiinka iyo ilaha kulaylka. Weelka wax lagu kaydiyo waa in la xidhaa. Walaxda waa in loo doortaa sida birta ama caag ah. Waa in laga fogeeyaa oksaydhiyeyaasha, asiidhyada xooggan, iyo saldhigyada xooggan. Tirada kaydinta waa in lagu xakameeyaa meel nabdoon si looga fogaado kaydinta xad dhaafka ah.

1. Xakamaynta deegaanka: Iska ilaali heerkulka sare iyo iftiinka qorraxda tooska ah si aad uga hortagto burburka hawada iyo qoyaanka awgeed; Heerkulka deegaanka ee aadka u sarreeya wuxuu keeni karaa kala-goys ama kordhinta khatarta kacsanaanta.

2. Shuruudaha weelka: Isticmaal weel gaar ah oo shaabadaysan (sida birta ama balaastiigga), oo mamnuuc isticmaalka weelasha birta si looga hortago falcelinta kiimikada; weelasha waa in laga ilaaliyo iftiinka lagana hubiyo in si joogto ah loo xidho.

3. Kaydinta go'doominta: Ku kaydi si gooni ah oksaydhiyeyaasha, acids xooggan, iyo saldhigyada xooggan si looga hortago arrimaha ku habboon ee sababi kara burburka ama shilalka badbaadada; waxa lagu talinayaa in la sameeyo meel lagu kaydiyo agabka halista ah.

4. Tallaabooyinka deg-degga ah: Bakhaarku waxa uu ku qalabaysan yahay qalabka dab-damiska (sida dab-bakhtiiyeyaasha xumbo) iyo qalabka degdegga ah ee daadsan (sida agabka adsorption); Haddii ay dhacdo in ay daadiso, isla markiiba ku dabool ciid ama lime engegan oo ururso si aad u tuurto.

Kiimikadayada sida aadka ah loo iibiyo waxaa ka mid ah dareerayaasha warshadaha iyo dhexdhexaadiyeyaasha kiimikaad, sida Taxanaha Alcohol, Taxanaha Ether, Esters, Precursor Series, Acid-Ester Solvents, Bacrimiyeyaasha NPK-Biyaha-Milan, iyo Kiimikada kale ee Warshadaha. Alaabooyinkani waxay ka kooban yihiin sahay deggan, nadiifnimo la isku halayn karo, iyo heerar tayo leh oo joogto ah. Weydiinta waa la soo dhawaynayaa.
