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 ballaaran loo isticmaalaa in lagu kala firdhiyo polymer budada RDP leh vinyl acetate iyo ethylene kopolymerized emulsion budada, ethylene iyo vinyl chloride iyo lauric acid vinyl ester ternary copolymer budada, vinyl acetate iyo ethylene iyo dufan acid vinyl ester ternary copolymer budada ah, saddexdan 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 furitaan ah, sii hoobiye iska caabin wanaagsan oo alkaline ah, wanaajiso xabagta hoobiyeyaasha, xoogga dabacsanaanta, biyuhu, caagnimada, xidhashada caabbinta iyo dhismaha, hoobiye dabacsan ee ka hortagga dildilaaca waxay leedahay dabacsanaan xoogan.

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 ballaadhan 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 aan degganayn oo dabiici ah (VOC) iyo sifooyin gaas cuncun oo hooseeya;

5, oo leh iska caabin uv heer sare ah iyo iska caabin kulayl oo 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 cabbiraadda 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 hooseeya 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.
