Polyurethane varnish - qalab dhameystir casri ah

Horumarinta tiknolojiyada casriga ah ee wax soo saarka ee qalabka dhameysteen u ogolaanaya in ay soo saaraan dhamaan waxyaabaha cusub oo cusub oo tiro ka mid ah sifooyin u gaar ah. novelties noocan oo kale ah waxay khusaysaa xamuurada polyurethane.

Macluumaadkaan waxaa wakiil ka ah xal Halabuurka kala duwan ee isocyanates polyfunctional hydroxyl. xamuurada polyurethane markii foomamka codsatay dushiisa of polymer adag la-dhismeedka saddex geesood ah. Marxaladani waxay dhacdaa ay sabab u tahay falcelinta ee isocyanates la qaybaha hydroxyl (polyesters dhamaystirnayn helay fal-celin ah ee xad-dhaaf ah ee khamriga polyhydric la acid ah dibasic ama la isku mid ah monobasic iyo acids dufan dibasic).

Inta badan loo isticmaalaa oo qayb ahaan hydrolyzed acetates polyvinyl, polyacetals dhamaystirnayn, esters cellulose, iyo ksilolformaldegidnye cusbi phenol-formaldehyde. Ka mid ah isocyanates loo isticmaalo diisocyanate inta badan loo isticmaalo, iyo isku kala duwan oo dhanba. Sidoo kale, waxay isticmaalaan diisocyanate hexamethylene iyo waxyaabaha reaction of diisocyanate xad-dhaaf ah oo la khamriga a polyhydric iyo hydroxyl kooban polyesters. La shaqaynta qalabka waxay u baahan tallaabooyin taxaddar ah oo gaar ah. Sidaa darteed waa ka badan wax ku ool ah si ay u isticmaalaan isocyanates ama "qarsoon" "xidhmey", xeryahooda kuwaas oo si fudud giirte marka kulul. Kooxdan waxaa ka mid ah waxyaabaha reaction of isocyanates la malonic, Ester acetoacetic, ethyleneimine iyo feniluretanom ah. lacquers polyurethane kala diri isticmaalaya esters, ketones, Consort warankiilada, nitroparaffins. Kuwani waxay qalab diluent waa xylene, toluene, hydrocarbon aliphatic.

lacquers polyurethane waxaa laga heli karaa sida hal qayb ama laba-qayb darey. In kiiska labaad si gooni gooni ah xal xeryahooda hydroxyl-ka kooban, ama isku mid ah kuwan xeryahooda iyo xalalka isocyanate diyaariyey hor inta aadan isticmaalin wakiilka this lagu qaso. Noocan oo kale ah diyaar u xamuurada laba qayb waxaa ka 4 ilaa 48 saacadood dhawray. blaastiigga noocan oo kale ah waxaa loo isticmaalaa daahan ee Daaweynta kulul iyo qabow. deggan blaastiigga Unlimited arkaa mid ka-qayb-kulul Asagoo arigtadaa ka dhigay ku salaysan ee loo yaqaan isocyanates "hor istaagay".

varnish polyurethane foomamka a dhalaalaya, blaastiigga laastikada la engegnaantiinna sare, Amda wanaagsan, guryaha dielectric sare iyo iska caabin ah kiimikada. Waxay sii kordheysa loo isticmaalay ilaalinta la taaban karo, biraha, meelaha alwaax iyo waxa loo isticmaalaa rinjiyaynta qalabka dhirta kiimikada, dikhaw iyo turxaan, on shirkadaha cuntada.

polyurethane Available varnish for parquet, alaabta guriga, caag, warqad, maqaar, dhismaha maraakiibta, leyloonka iyo bacyaal. daahan Tani waa mid aad raagaya iyo wax ku ool ah, waxa ay si weyn u kordhiyaa nolosha shelf ee alaabta kala duwan ee. blaastiigga One-ka kooban waxaa inta badan loo isticmaalaa ilaalinta copper, aluminium iyo biraha soo saarka.

biyo polyurethane VARNISH ilaaliya darbiyada iyo saqafka alwaax of caaryada iyo caariyaysi. Waa wax fudud iyo kulaylka u adkaysta. Tani daahan hufan u ogolaanaya si fiican u muujiyo quruxda dabiiciga ah oo qoryo.
