Uburyo bwo gushyira mu byiciro no gusenya HPMC

1. Gushyira mu byiciro:

HPMCishobora kugabanywamo ubwoko bw'ingufu zihita n'ubwoko bw'ingufu zishyushye. Ibikoresho by'ingufu zihita zikwirakwira vuba mu mazi akonje hanyuma zikabura mu mazi. Muri iki gihe, amazi nta mvubura aba afite, kuko HPMC ikwirakwira gusa mu mazi kandi nta gushonga nyakuri iba ifite. Nyuma y'iminota 2, mvubura y'amazi yariyongereye buhoro buhoro kugira ngo ikore colloid ibonerana kandi idafite ishingiro. Ibikoresho bishyushya, iyo bihuye n'amazi akonje, bishobora gukwirakwira vuba mu mazi ashyushye bikabura mu mazi ashyushye. Iyo ubushyuhe bugabanutse ku bushyuhe runaka, mvubura ihita igaragara buhoro buhoro kugeza igihe colloid ibonerana kandi idafite ishingiro ikozwe. Ubwoko bw'ingufu zishyushye bushobora gukoreshwa gusa mu ifu ya putty na mortier. Muri kole y'amazi n'irangi, ibintu bihuza bibaho kandi ntibishobora gukoreshwa. Ubwoko bw'ingufu zihita bukoreshwa mu buryo bwinshi. Bushobora gukoreshwa mu ifu ya putty na mortier, ndetse no mu kole y'amazi n'irangi, nta binyuranyo na kimwe.

2. Uburyo bwo gusenya:

Uburyo bwo gushonga amazi ashyushye: Kubera ko HPMC idashonga mu mazi ashyushye, HPMC ishobora gushonga mu mazi ashyushye mu ntangiriro, hanyuma igashonga vuba mu gihe cyo gukonjesha. Uburyo bubiri busanzwe busobanurwa butya: 1), shyira ingano ikenewe mu gikoresho cy'amazi ashyushye hanyuma ushyushye kugeza kuri dogere selisiyusi 70. Hydroxypropyl methylcellulose yongewemo buhoro buhoro uvanga buhoro buhoro, mu ntangiriro HPMC yarerembaga hejuru y'amazi, hanyuma buhoro buhoro ikora ururenda, rukonjeshwa uvanga. 2), ongeramo ingano ikenewe ya 1/3 cyangwa 2/3 by'amazi mu gikoresho, hanyuma ushyushye kugeza kuri dogere selisiyusi 70, ukurikije uburyo bwa 1), suka HPMC, tegura ururenda rw'amazi ashyushye; hanyuma ongeramo ingano isigaye y'amazi akonje mu mazi ashyushye. Mu rurenda, uruvange rwarakonjeshejwe nyuma yo kuvanga.

Uburyo bwo kuvanga ifu: Vanga ifu ya HPMC n'ibindi bintu byinshi birimo ifu, uvange neza ukoresheje icyuma gishongesha, hanyuma wongeremo amazi kugira ngo ishonge, hanyuma HPMC ishobora gushonga muri iki gihe idateranye, kuko buri mfuruka nto ifite HPMC nke gusa. Ifu izashonga ako kanya ihuye n'amazi. ——Ubu buryo bukoreshwa n'abakora ifu ya putty na mortier. [Hydroxypropyl methylcellulose (HPMC)ikoreshwa nk'ikintu gikomeza ubukonje no kubika amazi mu ifu ya putty]
