Liyini izinga lokushisa elincane le-film-forming (MFT) lama-polymer powders ahlakazeka kabusha?

I-Kima Chemical inganikeza ulwazi oluthile olujwayelekile ku-MFT nokubaluleka kwayo ekusebenzeni kwezimpushana ze-polymer ezihlakazeka kabusha.

I-MFT izinga lokushisa lapho i-polymer dispersion ingakha ifilimu eqhubekayo uma yomisiwe. Kuyipharamitha ebalulekile ekusebenzeni kwezimpushana ze-polymer ezihlakazeka kabusha ngoba zithinta ikhono lempushana ukwenza ifilimu ehlangene futhi eqhubekayo ku-substrate.

I-MFT yezimpushana ze-polymer ezihlakazeka kabusha ziyahlukahluka kuye ngohlobo lwe-polymer, usayizi wezinhlayiyana, kanye nokwakheka kwamakhemikhali. Ngokuvamile, izimpushana ze-polymer ezihlakazeka kabusha zinebanga le-MFT phakathi kuka-0°C kuya ku-10°C. Kodwa-ke, amanye ama-polymers angase abe ne-MFT ephansi njenge--10°C noma ifinyelele ku-20°C.

Ngokuvamile, i-MFT ephansi iyathandeka kuma-polymer powders ahlakazeka kabusha njengoba ivumela ukwakheka kwefilimu engcono emazingeni okushisa aphansi, okungabangela ukunamathela okuthuthukisiwe, ukuguquguquka, nokuqina kokugqoka. Kodwa-ke, i-MFT akufanele ibe phansi kakhulu njengoba ingabangela ukumelana namanzi okumpofu kanye nobuqotho befilimu.

Ekuphetheni, i-MFT ye-polymer powders ehlakazeka kabusha iyipharamitha ebalulekile ethinta ukusebenza kwe-coating. I-MFT ephelele incike ezidingweni ezithile zohlelo lokusebenza kanye nohlobo lwe-polymer esetshenzisiwe.
