Kev Tshawb Fawb Kom Txaus Siab txog Polyvinyl Alcohol Solubility Characteristics

Daim ntawv no qhia txog cov kev siv ntawm Polyvinyl Alcohol (PVA) thiab nws qhov solubility hauv ntau hom solvents xws li dimethyl, ethylene glycol, thiab ethanol, thiab muab ib qho chaw rau kev txiav txim siab txog peb cov khoom yuav pab tau li cas kom tau raws li ntau hom kev xav tau ntawm cov neeg siv khoom. PVA qhov versatility ua rau nws muaj nuj nqis hauv ntau hom lag luam, thiab yog li ntawd, qhov kev xav tau siab uas peb ua haujlwm raws li qhov xav tau kom tau raws li txhua qhov kev xav tau ntawm cov neeg siv khoom hauv Suav teb. Tsis hais txog cov haujlwm uas peb cov neeg siv khoom nrhiav, peb pab pawg muab txhua hom PVA khoom thaum xav tau hauv cov khoom viscous siab purity nrog cov yam ntxwv solubility ruaj khov.

Siab Zoo Assurance

Qeej ntawm cov tuam txhab loj tshaj plaws uas peb ua haujlwm nrog suav nrog Anhui Wanwei High-tech Materials Co., Ltd. Qhov kev koom tes no ua kom paub tseeb tias cov khoom polyvinyl alcohol yog qhov zoo, muaj peev xwm, thiab cov khoom. Kev tswj hwm zoo ntawm PVA ua kom muaj kev ua raws li cov qauv thoob ntiaj teb, yog li ntawd, kev ntseeg tau rau cov khoom yog siab thaum lawv raug siv hauv cov ntaub, glue, thiab cov khoom ntim vim lawv cov kev ua tau zoo.

## Peb Cov Khoom Polyvinyl Alcohol

Tsis muaj los yog PVA nyob hais tawm noj ntxhais, tau ntawv xovxwm, thiab lub. PVA los yog koj (DH ≥98%) mus qhia los yog 80°C thiab kho, rau txog cov lwm qhov ntsis los yog hais tawm thiab tsis muaj los yog. Nyob hais tawm koj (DH 87-89%) mus qhia los yog hais tawm thiab nyob hais tawm thiab nyob hais tawm thiab nyob hais tawm thiab nyob hais tawm. PVA ntawv xovxwm tebchaw yog qhia los yog tej thiab PVA ntawv xovxwm hauv-MW thiab nyob hais tawm thiab nyob hais tawm thiab nyob hais tawm thiab nyob hais tawm. Tsis muaj los yog yog tau ntawv: cov lwm qhov (≤100 mesh) yog qhia los yog 15-30 minutes, thiab cov lwm qhov tebchaw yog qhia los yog 1-2 hours. Solubility yog peak los yog 60-90°C, thiab modern formulations yog qhia los yog ≤20 minutes. Overheating (≥100°C) yog cause gelation, thiab adding salts or alcohols may decrease solubility. Rau hais tso, PVA 1799 (high DH, high MW) yog qhia los yog 95°C, rau txog cov lwm qhov ntsis los yog hais tawm thiab film casting, whereas PVA 0888 (low DH, low MW) yog qhia los yog 25°C thiab quick-apply adhesives.

Cov Lus Nug Feem Ntau Txog Polyvinyl Alcohol Solubility

Yuav ua li cas rau Polyvinyl Alcohol thaum muab tso rau hauv dej?

Polyvinyl Alcohol feem ntau yuav dissolved yooj yim heev thaum sib tov nrog dej, tshwj xeeb tshaj yog qhov hydrolyzed version. Cov solubility yuav txawv nrog cov hydrolysis thiab molecular hnyav hauv polymer PVA, tab sis hauv general, cov hnyav qis yuav dissolved sai dua li cov hnyav siab. Qhov no cov khoom ua rau PVA zoo rau kev siv hauv cov ntawv thov uas xav tau cov khoom uas muaj dej xws li coatings thiab adhesives.
