HPMC (ni ukuvuga hydroxypropyl methylcellulose) ni ikintu cy'ingenzi mu gukora amavuta ya tile. Itezimbere gufatana, gukora no kugumana amazi ya tile. Muri iyi ngingo, tuzaguha ubuyobozi bwuzuye bwo gukoresha HPMC muri tile adhesive progaramu.
1. Intangiriro kuri HPMC
HPMC ni selile itari ionic ether yabonetse muguhindura selile naturel. Igikorwa cyo gukora kirimo kuvura selile hamwe na alkali kugirango uyishonge, hanyuma wongereho methyl chloride na oxyde ya propylene kugirango uyihindure. Igisubizo ni ifu yera cyangwa idafite umweru byoroshye gushonga mumazi.
2. Ibiranga HPMC
HPMC ni polymer ihindagurika cyane hamwe nibintu byinshi byingenzi. Bimwe mubyingenzi byingenzi birimo:
- Kubika amazi meza
- gufatira hejuru
- Kunoza imashini
- Kunoza imiti igabanya ubukana
- Kongera imbaraga zo kurwanya kunyerera
- kugenda neza
- Kunoza amasaha yo gufungura
3. Ibyiza bya HPMC mugukoresha tile
Iyo ikoreshejwe mumashanyarazi ya tile, HPMC itanga ibyiza byinshi harimo:
- Kubika neza amazi kugirango ibikorwa bya tile bifatanye neza ahantu hatose
- Kunoza imitungo ifatika kugirango tile ifate neza
- Kunoza imashini zituma byoroha gukoreshwa kandi bikagabanya imbaraga zisabwa kugirango ugere ku buso bunoze
- Kugabanya kugabanuka no kugabanuka, kuzamura ubwiza bwimiterere ya tile
- Itezimbere ubudahwema bwa tile, biteza imbere kandi neza
- Kongera imbaraga zo kunyerera kugirango umutekano wiyongere hejuru ya tile
4. Gukoresha HPMC muri Tile Adhesive Porogaramu
HPMC ikoreshwa nkibibyimbye, bifata, bigumana amazi hamwe na rheologiya ihindura mugukoresha tile. Mubisanzwe wongeyeho 0.5% - 2,0% (w / w) yumvange yose yumye. Hano haribice bimwe byingenzi byo gukoresha HPMC.
4.1 Kubika amazi
Amatafari ya tile agomba gusigara adahwitse kugirango uyashire afite umwanya uhagije wo gutunganya tile. Imikoreshereze ya HPMC itanga amazi meza kandi ikabuza gufatira gukama vuba. Bisobanura kandi ko ibifatika bidakenera guhindurwa, bishobora kuganisha kumikorere idahuye.
4.2 Kunoza gukomera
Ibikoresho bifata HPMC byongera cyane imbaraga zububiko bwa tile. Ifasha kwemeza ko tile iguma mumutekano neza, ndetse no mumihanda minini cyangwa ahantu hatose.
4.3 Imashini
HPMC itezimbere imikorere yimigozi ya tile, byoroshye kuyikoresha no kugera kubutaka bworoshye. Bituma ibifata byoroha guhuza, bigabanya imbaraga zisabwa kugirango usunike hejuru.
4.4 Kugabanya kugabanuka no kugabanuka
Igihe kirenze, ifata ya tile irashobora kugabanuka cyangwa kugabanuka, bikavamo kurangiza bitagaragara kandi bidafite umutekano. Gukoresha HPMC bigabanya cyane kugabanuka no kugabanuka, byemeza kurangiza kimwe kandi cyiza.
4.5 Kunoza kunyerera
Kunyerera no kugwa ni akaga gakomeye hejuru ya tile, cyane cyane iyo itose. Kwiyongera kunyerera kwa HPMC bituma ibyuma bifata neza bikoreshwa neza kandi bigabanya ibyago byo kunyerera no kugwa.
5. Nigute ushobora gukoresha HPMC muri Tile Adhesive Porogaramu
HPMC isanzwe yongerwaho ku gipimo cya 0.5% - 2.0% (w / w) ivangwa ryumye. Igomba kubanza kuvangwa na sima ya Portland, umucanga nandi mafu yumye nibindi byongerwaho mbere yo kongeramo amazi. Hasi nintambwe zigira uruhare mugukoresha HPMC muri tile ifata porogaramu.
- Ongeramo ifu yumye kuvanga ibikoresho.
- Ongeramo HPMC kuvanga ifu
- Kangura ifu ivanze kugeza HPMC igabanijwe neza.
- Buhoro buhoro ongeramo amazi muruvange mugihe uzunguruka buri gihe kugirango wirinde kubyimba.
- Komeza guhina kugeza igihe ivanze ryoroshye kandi rifite umurongo umwe.
6. Umwanzuro
HPMC ni ikintu cy'ingenzi mu gukora ibiti bifata amatafari, bitanga inyungu z'agaciro nko kongera imbaraga, kunoza imikorere, no kugabanya kugabanuka no kugabanuka. Gukoresha HPMC muri tile yometseho bisaba kuvanga neza na dosiye kubisubizo byiza.
Kubwibyo, turasaba cyane gukoresha HPMC mugukora amatafari ya tile kugirango twishimire ibyiza byayo kandi tunoze ubwiza bwubuso bwuzuye.
