Habka tijaabi viscosity ee budada cinjirka ee dib loo cusboonaysiin karo

Waqtigan xaadirka ah, budada cinjirka ee sida aadka ah loo isticmaalo ee aduunka waxaa ka mid ah budada vinyl acetate iyo ethylene copolymer budada, ethylene, vinyl chloride iyo vinyl laurate ternary copolymer budada, vinyl acetate, ethylene iyo dufan sare oo vinyl ester ternary copolymer budada ah. Budada, saddexdan budada polymer dib loo cusboonaysiin karo ayaa xukuma suuqa oo dhan, gaar ahaan vinyl acetate iyo budada ethylene copolymer VAC / E, taas oo ku jirta booska hogaaminta ee garoonka caalamiga ah waxayna u taagan tahay astaamaha farsamada ee budada polymer dib loo cusboonaysiin karo. Weli xalka farsamada ugu fiican marka loo eego khibradda farsamada ee polymers-ka lagu dabaqay wax ka beddelka hoobiye:

1. Waa mid ka mid ah polymers-ka loogu isticmaalka badan yahay adduunka;

2. Waayo-aragnimada codsiga ee goobta dhismaha ayaa ah tan ugu badan;

3. Waxay buuxin kartaa sifooyinka rheological ee loo baahan yahay hoobiye (taas oo ah, dhismaha loo baahan yahay);

4. Xabagta polymer-ka ee leh monomers kale waxay leedahay sifooyin walxo aan isbeddelin oo hooseeya (VOC) iyo gaas cuncun hooseeya;

5. Waxay leedahay sifooyinka caabbinta UV ee aadka u fiican, caabbinta kulaylka wanaagsan iyo xasilloonida muddada dheer;

6. Iska caabbinta sare ee saponification;

7. Waxay leedahay heerkulka kala-guurka muraayadda ugu ballaaran (Tg);

8. Waxay leedahay isku xidhid dhammaystiran oo heer sare ah, dabacsanaan iyo sifooyin farsamo;

9. Waaya-aragnimada ugu dheer ee wax-soo-saarka kiimikaad ee sida loo soo saaro alaab tayo leh oo deggan iyo waayo-aragnimada ilaalinta xasilloonida kaydinta;

10. Aad bay u fududahay in lagu daro kolloid-ka ilaaliya (alkolada polyvinyl) oo leh waxqabad sare.

Habka lagu ogaanayo xoogga isku xidhka ee budada cinjirka ee dib loo cusboonaysiin karo waxaa lagu gartaa in habka go'aaminta uu yahay sida soo socota:

1. Marka hore, qaado 5g oo budada cinjirka ah oo dib loo cusboonaysiin karo oo ku rid koob cabbir ah, ku dar 10g oo biyo saafi ah oo walaaq 2 daqiiqo si aad si siman isugu walaaqdo;

2. Kadibna koobka cabbirka isku qasan ha istaago 3 daqiiqo, ka dibna walaaq mar kale 2 daqiiqo;

3. Ka dibna mari dhammaan xalalka koobka cabbirka saxan quraarad nadiif ah oo si siman loo dhigay;

4. Geli saxanka dhalada ah qolka tijaabada jilitaanka heerkulka heerkulka hooseeya ee DW100;

5. Ugu dambeyntii, ku rid xaaladda jilitaanka deegaanka ee 0 ° C 1 saac, soo saar saxanka dhalada, tijaabi heerka sameynta filimka, oo xisaabi xoogga isku xirnaanta caadiga ah ee budada cinjirka ee dib loo cusboonaysiin karo ee la isticmaalayo iyadoo loo eegayo heerka sameynta filimka .
