Mu nganda zubwubatsi, tile ifata ibikoresho byingenzi byubaka kandi bigakoreshwa cyane mugushira inkuta n'amagorofa. Tile ifata neza ko amabati afatanye neza, atanga ituze nigihe kirekire. Ariko, ibice birashobora kugaragara mugihe cyo gukoresha ibifatika, bidakugiraho ingaruka gusa ahubwo birashobora no kugabanya gushikama k'uburebure. Kugirango ugabanye ibibaho, HPMC (HydroxyPropyl Methylcellsellse) yakoreshejwe nkaho yongeyeho mugihe cyo kwishora mumyaka yashize. Ifite uruhare runini mugutezimbere imikorere yo gukora no kuzamura indwara ya crack.
1. Igitekerezo cyibanze cya HPMC
HPMC, cyangwa hydroxyPropyl methylcellse, ni uruganda rukora amazi ya polymer rwakozwe na fibre karemano (nkibiti cyangwa ipamba). Ifite amazi meza, ahisha, kubyimba no gukora firime. HPMC ikoreshwa cyane mumirima yubwubatsi, imiti, ibiryo no kwisiga, cyane cyane munganda bwubwubatsi, aho bikoreshwa nkuwabyimbye hamwe na minite.
2. Kurema muri Tile
Mugihe cyo gutwika ubumwe, ibice mubyiciro bya tile mubisanzwe biterwa nibintu bikurikira:
Guhumeka cyane ubushuhe: Niba ubuhemu bwahise buhita bwihuse mugihe cyimikorere ikomeye yo kugendera, birashobora gutera ibifatika byumye no gucamo. Cyane cyane mu bidukikije byumye cyangwa ibidukikije bihumeka, imyumvire ishingiye ku ingwate ibura ubuhemu vuba kandi ikunda gucamo.
Impinduka zubushyuhe: Impinduka zihuse mubushyuhe zirashobora gutera kwaguka no kugabanuka kwa substrate na tile. Niba ibifatika bidashobora guhuza nimpinduka, guca ibicana.
Subiramo ibintu bitari byiza: Itandukaniro mu bucucike, ubushuhe, kugorora, n'ibindi ku buso butandukanye budahagije cyangwa butaringaniye.
Ibibazo byiza bifite ireme: Umubare udakwiye mubisobanuro, wongeyeho imbaraga cyangwa ibindi bigize, cyangwa ibyo bigizeho bidakwiye bizatera ibifatika mugihe gito, bityo bitera uduce.
3. Uruhare rwa HPMC mu kugabanya ibice
Nkibyimbye byingenzi na binder, uruhare rwa HPMC muri tile ashimishijwe cyane cyane mubice bikurikira:
3.1 Kongera Adhesion
HPMC itezimbere guhindurana ibihangano, bityo bikamura amarangamutima hagati yimyizerere nubuso bwifatizo, kandi burashobora gukumira neza ko kumenagura no gucika intege. Amazi meza yoroheje kandi afite ubushishozi bushobora kwemeza ko umurego ushobora guhuzwa cyane kuri tile hamwe nubuso bwibanze mugihe cyo gukoresha.
3.2 Kunoza Kurwanya Kurwanya
Ongeraho HPMC kuri tile ingirakamaro irashobora kunoza cyane kurwanya. Imiterere ya HPMC ikubiyemo umubare munini wamatsinda ya hydroxyl na ether, bikaba bishobora kunoza neza plakiyeli kandi bikaba bishobora kugabanya ibice biterwa nubushyuhe buhinduka cyangwa guhangayikishwa no guhangayikishwa nubutaka mugihe gikomeye. Byongeye kandi, HPMC irashobora kandi kunoza ihohoterwa rishingiye ku gahato, gahoro gahoro gake y'amazi, kandi gabanya imigabane iterwa no kugabanuka kw'ibihangano bya sima.
3.3 Kunoza imikorere yubwubatsi
HPMC ifite ingaruka nziza cyane, gukora tile byoroshye gukora mugihe cyo kubaka. Mugihe cyo kubaka, HPMC irashobora gutera imbere amazi no kugarura ibintu, yongera kugumana amazi, kandi bigabanye amazi yihuta mugihe cyo kubaka. Ibi ntibifasha gusa kwagura igihe cyo kugihindura, ariko narwo twirinda gushiraho ibice biterwa nibikorwa bidakwiye.
3.4 Kunoza kurwanya ikirere
HPMC ifite uburwayi buhebuje no kurwanya ikirere. Nyuma yo kongeraho HPMC ku bushobozi bwo kumeneka, ubushobozi bwo kumenyekana bwo kurwanya imirasire ya ultraviolet iratera imbere, ishobora kurwanya neza ingaruka mbi z'ibidukikije byo hanze ku mikorere yacyo no kugabanya ibice byatewe n'ibidukikije.
3.5 Kongera kurwanya amazi
HPMC ifite ingaruka zikomeye kumazi kumazi, ishobora kunoza neza ibihangange byamazi no gukumira ibihangano byihuta. Mugutezimbere imikorere yumwanya, hpmc irashobora gukumira neza ubushuhe kwinjira mu rufatiro cyangwa ibifatika, bityo bikagabanya ibice no gukuramo ibibazo biterwa n'ubushuhe.
4. Imanza zihariye
Mubikorwa bifatika, HPMC ikoreshwa nkimwe mubyongeweho mugushiraho ibihangano. Benshi mu bizwi cyane bazwi cyane abakora bazahindura umubare nubwoko bwa HPMC yongeyeho ukurikije ibyo uturere dutandukanye hamwe nibidukikije byo kubaka kugirango babone ingaruka nziza zo kurwanya.
Mu bihe bimwe byumye cyangwa ahantu hatandukanye nubushyuhe bunini bwumutungo, kongeramo HPMC burashobora kunoza neza ibifatika byo kurwanya no gutandukana k'ubushyuhe. Mu bihe bitoshye, kugumana amazi ya HPMC no kurwanya umutekano birashobora kwirinda neza ibibazo biterwa n'amazi arenze cyangwa guhumeka nabi.
Nkibibazo byingenzi muri tile anegura, HPMC irashobora kunoza neza imikorere yingirakamaro, cyane cyane mubijyanye no kurwanya igikona. Ifasha kugabanya ibyago byo gucengera muri tile ashimishijwe no kuzamura ingufu, ibitana, imikorere yo kubaka, imikorere yo kubaka, no kurwanya ikirere. Kubwibyo, mubyakozwe no kubaka ubumwe, ikoreshwa rya HPMC ni igisubizo cyiza, gitanga ingwate ikomeye yo kunoza ireme ry'imiterere no kubungabunga ubuziranenge.
