HPMC muburyo bwo kubaka no gusiga irangi

Hydroxypropyl methylcellulose (HPMC mu magambo ahinnye) ni ether yingenzi ivanze, ikaba ari polymer idafite amazi ya elegitoronike, kandi ikoreshwa cyane mubiribwa, ubuvuzi, inganda z’imiti ya buri munsi, gutwikira, reaction ya polymerisation no kubaka nko guhagarika ikwirakwizwa, kubyimba, kwigana, gutuza no gufatira hamwe, nibindi, kandi hariho icyuho kinini kumasoko yimbere mu gihugu.

Kuberako HPMC ifite ibintu byiza cyane nko kubyimba, emulisiyoneri, gukora firime, kurinda colloid, kugumana ubushuhe, gufatira hamwe, kurwanya enzyme no kutagira imbaraga za metabolike, ikoreshwa cyane mubitambaro, reaction ya polymerisation, ibikoresho byubaka, umusaruro wamavuta, imyenda, ibiryo, ubuvuzi, Koresha buri munsi ububumbyi, ibikoresho bya elegitoronike nimbuto zubuhinzi nandi mashami.

Building ibikoresho

Mubikoresho byubwubatsi, HPMC cyangwa MC mubisanzwe byongerwa kuri sima, minisiteri, na minisiteri kugirango bitezimbere ubwubatsi n’amazi meza.

HPMC irashobora gukoreshwa kuri:

1). Ibikoresho bifata kandi bifata ibyuma bya gypsumu;

2). Guhambira amatafari ashingiye kuri sima, amabati n'imfatiro;

3). Amashanyarazi ashingiye kuri plaque;

4). Isima ishingiye kuri sima;

5). Muri formula yo gusiga irangi no gukuraho amarangi.

Inganda

Mu nganda zo gusiga amarangi, HPMC ikoreshwa cyane mu gusiga irangi rya latex hamwe n’ibikoresho byo gusiga irangi ryamazi nkibikoresho bikora firime, kubyimbye, emulifier na stabilisateur.

Guhagarika Polymerisation ya PVC

Umurima ufite ibicuruzwa byinshi bya HPMC mugihugu cyanjye ni guhagarika polymerisation ya vinyl chloride. Muguhagarika polymerisation ya vinyl chloride, sisitemu yo gutatanya igira ingaruka itaziguye kumiterere yibicuruzwa PVC resin no kuyitunganya nibicuruzwa; irashobora kunoza ubushyuhe bwumuriro wa resin no kugenzura ingano yikwirakwizwa (ni ukuvuga guhindura ubwinshi bwa PVC). Umubare wa HPMC uhwanye na 0.025% ~ 0.03% yumusaruro wa PVC.

PVC resin yateguwe na HPMC yo mu rwego rwo hejuru, usibye kwemeza ko imikorere yujuje ubuziranenge bwigihugu, ifite kandi imiterere myiza yumubiri, ibintu byiza biranga uduce twiza hamwe nimyitwarire myiza ya rheologiya.

Oinganda

Izindi nganda zirimo cyane cyane kwisiga, kubyara amavuta, ibikoresho byo kwisiga, ububumbyi bwo murugo nizindi nganda.

Water soluble

HPMC ni imwe mu mazi ashonga ya polymer, kandi gukemura kwayo kwamazi bifitanye isano nibiri mumatsinda ya mikorerexyl. Iyo ibiri mumatsinda ya mikorerexyl ari muke, birashobora gushonga muri alkali ikomeye kandi idafite aho bihurira na termodinamike. Hamwe no kwiyongera kwa vitamine, irumva cyane kubyimba amazi no gushonga mumazi ya alkali na alkali idakomeye. Iyo ibirimo metoxyl ari> 38C, birashobora gushonga mumazi, kandi birashobora no gushonga muri hydrocarbone ya halogene. Niba aside irigihe yongewe kuri HPMC, HPMC izahita ikwirakwira mumazi idatanga ibintu bya keke bitangirika. Ibi biterwa ahanini nuko aside irike ifite amatsinda ya dihydroxyl mumwanya wa ortho kuri glycogene yatatanye.
