Sidee loo tijaabiyaa budada polymer-ka ee dib loo kala firdhin karo ee RDP?

Habka tijaabada ah ee sifooyinka iyo viscosity-ga budada polymer-ka ee dib loo kala diri karo RDP, Adduunka oo dhan waxaa si weyn loogu isticmaalaa in lagu kala firdhiyo budada polymer-ka RDP oo leh vinyl acetate iyo budada emulsion-ka ee ethylene copolymerized, ethylene iyo vinyl chloride iyo lauric acid vinyl ester ternary copolymer budada, vinyl acetate iyo ethylene iyo senior fatty acid vinyl ester ternary copolymer budada, saddexdan si ay u kala firdhiyaan budada polymer-ka RDP suuqa oo dhan, gaar ahaan vinyl acetate iyo ethylene copolymer budada VAC/E. Waxay ku jirtaa booska hormuudka ka ah goobta caalamiga ah waxayna matalaysaa astaamaha farsamada ee budada polymer-ka ee dib loo kala diri karo RDP.

Budada polymer-ka ee dib loo cusboonaysiin karoRDP waxay leedahay xoog isku xidhnaan oo heer sare ah, waxay hagaajisaa dabacsanaanta hoobiyaha waxayna leedahay waqti furitaan oo dheer, waxay siisaa hoobiye iska caabin alkaline oo heer sare ah, waxay hagaajisaa isku dhejinta hoobiyaha, xoogga dabacsanaanta, biyaha aan biyuhu gelin, balaastignimada, iska caabinta xirashada iyo dhismaha, hoobiyaha ka hortagga dillaaca dabacsan wuxuu leeyahay dabacsanaan xooggan.

Laga soo bilaabo waayo-aragnimada farsamo ee polymer-ka wax laga beddelay hoobiyaha, wali waa xal farsamo oo ka wanaagsan:

1, RDP waa mid ka mid ah polymer-yada ugu isticmaalka badan adduunka.
2, Khibrad ballaaran oo ku saabsan adeegsiga dhismaha;

3, waxay buuxin kartaa shuruudaha sifooyinka rheological-ka ee hoobiyaha (taasi waa, dhismaha loo baahan yahay);

4, oo leh monomer polymer resin kale wuxuu leeyahay walxo firfircoon oo hooseeya (VOC) iyo astaamo gaas oo yar oo cuncun leh;

5, oo leh iska caabin UV oo aad u fiican iyo iska caabin kulayl oo wanaagsan iyo xasillooni muddo dheer ah;

6, oo leh iska caabin sare oo saponification ah;

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

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

9, waxqabad fudud oo la mid ah oo isku-darka ilaalinta kolloid (polyvinyl alcohol).

Habka lagu ogaanayo xoogga dhejiska ee budada polymer-ka ee dib loo kala firdhin karo ee RDP waxaa lagu gartaa hababka go'aaminta ee soo socda:

1, marka hore ku shub budada polymer-ka ee dib loo kala diri karo RDP 5g koob cabbir ah, ku dar 10g oo biyo saafi ah oo walaaq 2 daqiiqo, si siman isugu qas;

2. Koobka cabbirka isku dhafan u deji 3 daqiiqo oo mar kale walaaq 2 daqiiqo;

3. Ku mari dhammaan xalka koobka cabbirka saxan galaas oo siman oo nadiif ah;

4, saxanka galaaska geli sanduuqa tijaabada jawiga heerkulka hooseeya ee DW100;

5, ugu dambeyntii lagu meeleeyay xaaladaha jilitaanka deegaanka ee 0°C muddo 1 saac ah, ka saar saxanka galaaska, tijaabi heerka sameynta filimka, iyadoo loo eegayo beddelka heerka sameynta filimka ee budada polymer-ka ee dib loo kala firdhin karo ee RDP iyadoo la adeegsanayo xoogga isku xirka caadiga ah.
