HPMC kuri EPS Ubushyuhe bwo Kubika Amashanyarazi

HPMC, cyangwa hydroxypropyl methylcellulose, ikoreshwa cyane mugukora EPS (yaguye polystirene) minisiteri yubushyuhe. Iyi minisiteri ikoreshwa muguhuza imbaho ​​za EPS kubutaka butandukanye, nka beto, amatafari, nimbaho.

Imwe mu miterere yingenzi ya HPMC ituma iba ingirakamaro muri minisiteri yubushyuhe bwa EPS nubushobozi bwayo bwo gukora nkibibyimbye na rheologiya. Kwiyongera kwa HPMC kuri minisiteri itezimbere imikorere yayo no gukwirakwira, byoroshye kuyikoresha no gukorana nayo. HPMC kandi itezimbere ubudahwema no gutuza kwa minisiteri, bikagabanya ibyago byo kugabanuka cyangwa gusinzira mugihe cyo gusaba.

Usibye kuba ifite umubyimba, HPMC ikora kandi nk'umushinga uhuza kandi ugakora firime muri minisiteri ya EPS yumuriro. Kwiyongera kwa HPMC kuri minisiteri kunoza kwizirika kuri substrate no kubibaho bya EPS, bigakora umurunga ukomeye kandi uramba. HPMC ikora kandi firime ikingira hejuru ya minisiteri, ifasha kuyirinda ikirere n’isuri.

Iyindi nyungu yo gukoresha HPMC muri EPS yubushyuhe bwumuriro ni uko ishobora gufasha kugabanya kwinjiza amazi muri minisiteri. Ibi ni ngombwa kuko kwinjiza amazi menshi birashobora gutuma imikorere yubushyuhe igabanuka kandi byongera ibyago byo gukura kworoshye.

HPMC nayo ifitiye akamaro ibidukikije. Nibisanzwe, bishobora kuvugururwa, na biodegradable polymer ikomoka kuri selile, ikungahaye cyane mubihingwa. Ntabwo ari uburozi kandi ntabwo irekura ibintu byangiza ibidukikije.

iyongerwaho rya HPMC kuri EPS yumuriro wa minisiteri itanga inyungu nyinshi, zirimo kunoza imikorere, gukomera, no kuramba. HPMC ifasha kandi kurinda minisiteri ikirere n’isuri, kandi irashobora kugabanya kwinjiza amazi. Ninyongera yangiza ibidukikije.
