Hydroxypropyl MethylCellulose (HPMC) ikora
CAS: 9004-65-3
Hydroxypropyl MethylCellulose (HPMC) cyangwahypromelloseni amazi ya methyl selulose ether, akoreshwa cyane mubwubatsi, imiti, ibiryo, kwisiga, ibikoresho byo kwisiga, amarangi, nkibyimbye, emulisiferi, firime-yahoze, ihuza, ikwirakwiza, colloide ikingira. Turashobora gutanga icyiciro gisanzwe HPMC, twe irashobora kandi gutanga HPMC yahinduwe ukurikije ibyo abakiriya bakeneye. Nyuma yo guhindurwa no kuvura hejuru, dushobora kubona ibicuruzwa bikwirakwizwa mumazi vuba, bikongerera igihe cyo gufungura, anti-sagging, nibindi.

Porogaramu zisanzwe za HPMC:
Amatafari
Ret Kubungabunga amazi meza: igihe kinini cyo gufungura bizatuma tiling ikora neza.
Kunoza kwifata no kurwanya kunyerera: cyane cyane kumatafari aremereye.
Work Gukora neza: amavuta na plastike ya plaster biremewe, minisiteri irashobora gukoreshwa byoroshye kandi byihuse.
Isima ya sima / Yumye ivanze
● Byoroshye kuvanga amata bitewe no gukonjesha amazi akonje: kwibumbira hamwe birashobora kwirindwa byoroshye, nibyiza kumatafari aremereye.
Ret Kubungabunga amazi meza: kwirinda gutakaza amazi kuri substrate, amazi akwiye abikwa muruvange rutanga igihe kirekire.
● Kongera amazi akenewe: kongera igihe cyo gufungura, kwagura agace ka spry no gushiraho ubukungu.
Gukwirakwiza byoroshye no kunanirwa kugabanuka bitewe no kunoza imiterere.
Urukuta
Ret Kubika amazi: amazi menshi cyane.
● Kurwanya kugabanuka: mugihe ukwirakwiza ikote ryinshi rishobora kwirindwa.
Kongera umusaruro wa minisiteri: ukurikije uburemere bwuruvange rwumye hamwe nuburyo bukwiye, HPMC irashobora kongera ubwinshi bwa minisiteri.
Sisitemu yo hanze no kurangiza sisitemu (EIFS)
● Kunoza neza.
Ubushobozi bwiza bwo guhanagura kubuyobozi bwa EPS na substrate.
Kugabanya kwinjira mu kirere no gufata amazi.
Kwishyira hejuru
Kurinda amazi no gutembera kw'ibintu.
● Nta ngaruka ziterwa no gutembera neza
HPMC, mugihe ibiranga kubika amazi byongera imikorere yo kurangiza hejuru.
Kuzuza Crack
Work Gukora neza: ubunini bukwiye hamwe na plastike.
Ret Kubungabunga amazi bituma akazi kamara igihe kirekire.
Res Kurwanya Sag: kunoza ubushobozi bwo guhuza minisiteri.
