Shuangxin Gohsenol (PVOH·PVA) GH-22
Piav qhia
Saib xyuas
Gohsenol (PVOH·PVA) nrog qhov zoo heev ntawm dej soluble, adhesion, film forming thiab chemical stability. Nws yog qhov dav siv los ntawm cov neeg siv hauv tsev thiab txawv teb chaws hauv binder, ntawv coating agent, emulsifier, suspension agent, fiber, film thiab lwm yam khoom raw industrial thiab txheej txheem agent applications.

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.
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.
Processing Daim Ntawv
Nyog kev tsim kho ntawv, cov polyvinyl alcohol yog ib qho khoom siv zoo heev uas tuaj yeem pab huvav kom zoo dua thiab ua haujlwm zoo dua los ntawm kev ua nrog tib lub zog ntawm "qeeb pov ntawv-kev nyob rau hauv-sib txuas ntawv". Nws muaj peev xwm zoo heev hauv kev huvav, kev sau ntawv, kev tiv thaiv dej thiab kev saib xyuas pob ze, thiab tseem yog ib yam uas tsis muaj leej twg hnav tau hauv kev tsim kho ntawv zoo thiab ntawv ua haujlwm siab.
Kev Ncav Duab Pov
Polyvinyl alcohol raug siv los ntawm ib qho ua pov kom zoo dua kom pov zoo dua thiab kom tsis hnov mob, kom tsawg tus pov breaking hauv kev tsim kho, thiab pab kom zoo dua hauv kev tsim kho lwm yam.
Pob
20 kg/hnab.
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.
