Tsis lawm
Alcohol Polyvinyl tau ua rau muaj "kev nthuav dav" hauv cov roj ntxuav los ntawm 4 qhov: film-forming reinforcement, interface bonding, kev lag luam thiab kev kho tshuaj nrog. Qhov tseeb ntawm nws yog qhov zoo ua ke ntawm kev ceev thiab kev ua kom zoo (ua kom zoo dua qhov ua kom tsis txawv thiab sib txuas), kev ua kom haum (xav txog ob peb yam xaus thiab kev ua kom sov), thiab kev tiv thaiv kho mob thiab kev ua kom yooj yim (tsis lom neeg, ua kom raug, thiab khawm emulsion). Cov lej yuav tsum tau pom nrog lub sijhawm.
Daim Ua Rau Ntawv Hlau
Polyvinyl alcohol yog siv los tsim daim ua rau ntawv hlau, uas yuav hlau huv rau hauv dej thiab kho kom zoo rau qhov chaw nyob.
Vaj Tse Siv Lub Raj Thav Duab Siab
Polyvinyl alcohol ua tus kheej loj hauv vaj tse siv lub raj thav duab siab thiab muaj peev xwm ua kom zoo dua rau qhov sov thiab txhim kho qhov kev sib dhos ntawm lub raj hlau thiab cov ntsiab lus, ua kom qhov kev ua haujlwm tso cai thiab kho kom tsawg qhov kev txwv rau qhov chaw nyob.
Tsim Ntawv
Nyob rau hauv kev tsim ntawv, polyvinyl alcohol tau menjadi ib yam khoom siv rau kev ua kom zoo dua rau ntawv los ntawm qhov kev ua haujlwm ob peb hom ntawm "kev ua kom sov-sov ua daim ntawv hlau-kev ua kom zoo ntawm kev ntxig", qhov tseeb yog nws qhov ua kom zoo ntawm qhov sov, kev tiv thaiv dej thiab kev sau rau ntawv, thiab nws lub cev zoo, tsis muaj neeg ua rau lom neeg thiab ua kom hlau huv los ntawm kev hlau huv.
Cov pob
20 kg/ib, 25 kg/ib.
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.
