Kev Pov Daim Ntawv Thiab Kev Kuaj
Polyvinyl alcohol tau los ntawm qhov ntau tshwj xeeb hauv kev pov daim ntawv vim li qhov zoo hauv kev ua lub voj voos, kev nyob deb thiab kev raug zoo nkawv. Nws txhawm rau zoo dua li qhov zoo hauv kev lag luam (siab siab, zoo siab) tab sis kuj tso cai rau cov daim ntawv muaj qhov zoo hauv kev kho mob (acetalization).
Processing Daim Ntawv
nyob rau hauv kev pov daim ntawv, polyvinyl alcohol yog ib qho khoom siv zoo heev uas pab txhim kho qhov zoo ntawm daim ntawv los ntawm qhov kev ua haujlwm "pov npoo - nyob deb ntawm pigment - roj mus lub zog." Qhov no muaj qhov zoo heev hauv kev zoo, kev sau sai, kev tiv thaiv dej thiab kev saib xyuas dhia siab, thiab tseem yog ib yam uas tsis tuaj yeem kho kom zoo dua rau daim ntawv zoo thiab daim ntawv siv theej xwb.
Cov txog xyoo
Alcohol Polyvinyl hauv kev ncaj ncees tuaj yeem ua raws li qhov kev pab tiv thaiv, sib txuas zoo thiab ua rau yooj yim dua. Nws cov nuj nqo ua haujlwm yog tiv thaiv kho mob, sib txuas zoo thiab ua rau yooj yim dua, thiab nws yog ib qho tsim nyog rau cellulose substrates.
Forming board adhesive
Polyvinyl alcohol yog qhov adhesive nyob rau hauv kev tsim tawm board adhesives los ntawm nws qhov siab bonding strength, kho tau cov water resistance thiab environmental safety. Nws yog qhov zoo rau cov chaw xws li gypsum boards thiab wood chip boards uas xav tau qhov mechanical properties thiab environmental friendliness.

Khaws
- Nyob hauv chav qhuav, muaj huab cua zoo, nrog qhov kub nruab nrab ntawm 5-30°C.
- Khaws deb ntawm qhov chaw kub, khaws deb ntawm qhov qhuav, thiab zam kev pom rau hnub.
- Nws yog qhov tsis pub dhau kom khaws cia ua ke nrog cov tshuaj muaj zog kom tsis txhob muaj adsorption thiab kev puas tsuaj.
