Ihe kpatara eji eji hydroxypropyl methylcellulose eme ihe n'ọtụtụ ebe

A na-eji Hydroxypropyl methylcellulose eme ihe ugbu a n'akụkụ niile nke ndụ. Kedu ụdị akụrụngwa ọ bụ?

Site n'echiche anụ ahụ, hydroxypropyl methylcellulose bụ ether cellulose na-abụghị ionic, ntụ ntụ na-acha ọcha, na enweghị ụtọ. N'ime ụlọ ọrụ ihe owuwu, enwere ike iji ya dị ka ihe na-ejigide mmiri na retarder maka ciment mortar iji mee ka ngwa ngwa na-agbapụta.

Ndị a bụ ụfọdụ njirimara hydroxypropyl methylcellulose:

1. Site na nkwụsi ike ya dị mma, emulsion na mmiri-soluble resin coatings nwere ike iji dị ka emulsifiers, stabilizers na thickeners, wdg, nke mere ka mkpuchi na-eyi na-eguzogide ọgwụ na nrapado, na-ekwe ka kwụsie ike PH uru.

2. O nwere njide mmiri. Ọrụ bụ isi nke hydroxypropyl methylcellulose putty powder bụ na m nwere ike idowe mmiri ma rụọ ọrụ nke mmanu na nrapado. Ọ na-eme ka nkwụsi ike na-ebelata na akpụkpọ onwe ya ka ọ ghara igbochi ihe na-eme ntụ ntụ.

3. Ọ nwere ezi dispersibility na sịntetik resins. Dị ka ihe na-echebe gị n'ụlọnga, hydroxypropyl methylcellulose nwere ike ịrụ ọrụ dị mkpa n'igbochi mkpokọta nke polymer ahụ na imeziwanye nkwụsi ike nke resin urughuru dispersion.

Na mgbakwunye na ihe ndị a, hydroxypropyl methylcellulose, nakwa dị ka ezigbo ndim, adhesion siri ike, ihe owuwu na àgwà ndị ọzọ, a pụrụ ịhụ na arụmọrụ ya dị ezigbo mma. N'ihi ọrụ ndị a, a na-eji hydroxypropyl methylcellulose eme ihe n'ọtụtụ ụlọ ọrụ, dị ka ụlọ ọrụ ihe owuwu, ụlọ ọrụ mkpuchi, wdg, na hydroxypropyl methylcellulose dị mkpa.
