Sidee loo tijaabiyaa budada polymer dib loo kala diri karo RDP?

Habka tijaabada ee guryaha iyo viscosity ee budada polymer redispersible RDP, Worldwide waxaa si weyn loo isticmaalaa in lagu kala firdhiyo polymer budada RDP leh vinyl acetate iyo ethylene kopolymerized emulsion budada ah, ethylene iyo vinyl chloride iyo lauric acid vinyl ester ternary copolymer budada, vinyl acetate iyo ethylene acid budada ah Senior ethylene. si loo kala firdhiyo budada polymer RDP ee suuqa oo dhan, gaar ahaan vinyl acetate iyo budada ethylene copolymer VAC / E, Waxay ku jirtaa booska hogaaminta ee garoonka caalamiga ah waxayna ka dhigan tahay sifooyinka farsamada ee budada polymer dib loo cusboonaysiin karo.

Budada polymer dib loo cusboonaysiin karoRDP waxay leedahay awood dammaanad oo heer sare ah, waxay wanaajisaa dabacsanaanta hoobiye waxayna leedahay waqti dheer oo furan, sii hoobiye caabbinta alkaline heer sare ah, hagaajinta adhesion of adhesion hoobiye, xoog dabacsanaan, biyuhu, caag, xidhashada caabbinta iyo dhismaha, in hoobiye dabacsan anti-crack leeyahay dabacsanaan xoog leh.

Laga soo bilaabo waayo-aragnimada farsamada ee polymer-ka lagu beddelay hoobiye, weli waa xal farsamo oo ka wanaagsan:

1, RDP waa mid ka mid ah polymers-ka loogu isticmaalka badan yahay adduunka.
2, Khibrad codsi oo ballaaran oo ku saabsan dhismaha;

3, buuxin kara shuruudaha guryaha rheological hoobiye (taas oo ah, dhismaha loo baahan yahay);

4, oo leh xabagta monomer-polymer-ka kale waxay leedahay walxo isbedbeddelaya organic hooseeya (VOC) iyo sifooyin gaasta xanaaqa oo hooseeya;

5, oo leh caabbinta uv aad u fiican iyo iska caabin kulayl wanaagsan iyo xasilloonida muddada dheer;

6, oo leh caabbinta saponification sare;

7, oo leh heerkul ballaadhan oo galaas ah (Tg);

8, oo leh xidhid dhammaystiran oo heer sare ah, dabacsanaan iyo sifooyin farsamo;

9, hawl fudud oo la mid ah isku darka kolloid-ka-ilaalinta (alkolada polyvinyl).

Habka lagu ogaanayo xoogga xabagta ee budada polymer dib loo cusboonaysiin karo waxaa lagu gartaa hababka soo socda ee go'aaminta:

1, marka hore qaado budada polymer dib loo cusboonaysiin karo RDP 5g galaas koob cabbir ah, ku dar 10g biyo saafi ah oo walaaq 2min, ka dhig mid isku dhafan;

2. Dhig koobka cabirka isku qasan 3daqiiqo oo mar kale walaaq 2min;

3. Ku dhaji dhammaan xalalka koobka cabbirka saxan quraarad nadiif ah oo siman;

4, geli saxanka dhalada ah sanduuqa tijaabada jilitaanka heerkulka heerkulka hoose ee DW100;

5, ugu dambeyntii lagu meeleeyay 0 ° C xaaladaha jilitaanka deegaanka ee saacadda 1, soo saar saxanka dhalada, tijaabi heerka sameynta filimka, marka loo eego beddelka heerka sameynta filimka ee budada polymer dib loo cusboonaysiin karo ee RDP iyadoo la adeegsanayo xoogga isku xirnaanta caadiga ah.
