Nigute ushobora kugerageza ifu ya polymer isubirwamo RDP?

Uburyo bwo kwipimisha kumitungo no kwiyegereza ifu ya polymer isubirwamo RDP, Kwisi yose ikoreshwa cyane mugukwirakwiza ifu ya polymer RDP hamwe na vinyl acetate na Ethylene copolymerized ifu ya emulsion, Ethylene na vinyl chloride na acide lauric vinyl ester ternary copolymer ifu, vinyl acetate na etylene hamwe namavuta menshi. aside vinyl ester ternary copolymer ifu, izi eshatu zo gukwirakwiza ifu ya polymer RDP muri isoko yose yiganje cyane cyane vinyl acetate na Ethylene copolymer ifu ya VAC / E, Ifite umwanya wambere mumwanya wisi kandi igaragaza ibimenyetso bya tekiniki biranga ifu ya polymer RDP.

Ifu ya polymer isubirwamoRDP ifite imbaraga zidasanzwe zububiko, itezimbere ubworoherane bwa minisiteri kandi ifite igihe kinini cyo gufungura, guha minisiteri irwanya alkaline nziza, kunoza imiterere ya minisiteri, imbaraga zoroshye, izirinda amazi, plastike, kwambara no kubaka, muri minisiteri irwanya anti-crack ifite ihinduka ryoroshye.

Uhereye kuburambe bwa tekinike ya polymer yahinduwe na minisiteri, biracyari igisubizo cyiza cya tekiniki:

1, RDP nimwe muma polymers akoreshwa cyane kwisi.
2, Uburambe bwagutse bwo gusaba mubijyanye nubwubatsi;

3, irashobora kuzuza ibisabwa mumitungo ya rheologiya (ni ukuvuga kubaka bikenewe);

4, hamwe nizindi monomer polymer resin ifite ibintu bihindagurika bihindagurika (VOC) nibiranga gaze nkeya;

5, hamwe nibyiza birwanya uv hamwe nubushyuhe bwiza hamwe nigihe kirekire;

6, hamwe na saponification yo hejuru;

7, hamwe n'ubushyuhe bwagutse bw'ikirahure (Tg);

8, hamwe nibyiza cyane guhuza byuzuye, guhinduka hamwe nubukanishi;

9, byoroshye kandi bisa nibikorwa byo gukingira colloid (alcool polyvinyl).

Uburyo bwo gutahura imbaraga zifatika zifata ifu ya polymer RDP irangwa nuburyo bukurikira bwo kugena:

1, banza ufate ifu ya polymer isubirwamo RDP 5g mugikombe gipima ikirahure, ongeramo 10g amazi meza hanyuma ukangure kuri 2min, ubivange neza;

2. Shiraho igikombe kivanze cyo gupima kuri 3min hanyuma wongere ukangure kuri 2min;

3. Siga igisubizo cyose mugikombe cyo gupima ku isahani isukuye itambitse;

4, shyira isahani yikirahure muri DW100 ubushyuhe buke bwibidukikije bigereranywa;

5, amaherezo ashyirwa muri 0 ° C muburyo bwo kwigana ibidukikije kumasaha 1, fata isahani yikirahure, ugerageze igipimo cyo gukora firime, ukurikije igipimo cyo gukora firime ihinduranya ifu ya polymer isubirwamo RDP ukoresheje imbaraga zisanzwe zihuza.
