HPMC, izwi kandi nka hydroxypropyl methylcellulose, ni inyongera ikoreshwa mu nganda zitandukanye. Mu nganda zubaka, HPMC ikoreshwa cyane mubikoresho bishingiye kuri sima nka poro ya putty, gypsum, na sima ya sima. HPMC igira uruhare runini mugutezimbere imikorere yifu yifu itanga imikorere myiza, imbaraga zifatika hamwe nuburyo bwo kubika amazi. Ariko, iyo HPMC ikoreshejwe ifu yuzuye, ibintu byitwa "kubira". Muri iki kiganiro, turasesengura ibitera ibisebe tunaganira ku buryo bwo kubikumira.
Ibibyimba ni iki kandi kuki bibaho?
Ibibyimba ni ibintu byo guhumeka ikirere cyangwa ibisebe hejuru yifu yifu nyuma yo kubaka. Ibi birashobora guhita bibaho nyuma yo gusaba cyangwa nyuma yigihe runaka, bitewe nimpamvu yabyo. Ibibyimba bishobora guterwa nimpamvu nyinshi zirimo gutegura nabi substrate, gukoreshwa mubihe bidukikije cyangwa gukoresha ibikoresho bidahuye. Impamvu zitera ifuro rya HPMC nifu ya putty nizi zikurikira:
1. Kudahuza hagati ya HPMC nizindi nyongeramusaruro: HPMC ikoreshwa kenshi ifatanije nizindi nyongeramusaruro nka superplasticizers, retarders, hamwe nibintu byinjira mu kirere. Ariko, niba izo nyongeramusaruro zidahuye nizindi, ifuro rishobora kuvamo. Ibi bibaho kubera ko inyongeramusaruro zibangamira ubushobozi bwa buri wese bwo gukora imirimo yagenewe, bikavamo imvange idahwitse hamwe no kudahuza neza na substrate.
2. Kuvanga bidahagije: Iyo HPMC ivanze nifu ya putty, kuvanga neza nibyingenzi. Kuvanga bidahagije birashobora gutuma HPMC ifatanyiriza hamwe igakora ibirwa bivanze. Ibi birwa bitera ahantu hafite intege nke hejuru yifu ya putty, ishobora gutera ibisebe.
3. Kubika amazi: HPMC izwiho kubika amazi, nibyiza kubifu. Ariko niba ifu ya putty ibonye ubuhehere bwinshi, bizatera ibisebe. Ubusanzwe bibaho iyo ifu ya putty ikoreshwa mugihe cy'ubushyuhe bwinshi cyangwa hejuru yubutaka butarakize neza.
4. Tekinike yo gusaba nabi: Tekinike yo gukoresha nabi irashobora no gutera ibisebe. Kurugero, niba putty ikoreshwa cyane, irashobora gutega imifuka yumuyaga munsi yubuso. Ibibyuka byo mu kirere birashobora kwaguka bigatera ifuro. Mu buryo nk'ubwo, niba putty ishyizwe mubikorwa byihuse cyangwa nimbaraga nyinshi, bizashiraho umubano udakomeye hamwe na substrate, nayo ishobora gutera ibisebe.
Uburyo bwo kwirinda ibicurane
Kwirinda ifuro mugihe ukoresheje HPMC nifu ya putty bisaba kwitondera neza ibikoresho, tekiniki nibidukikije birimo. Dore zimwe mu nama zo kwirinda ibisebe:
1. Hitamo inyongeramusaruro zihuye: Mugihe ukoresheje HPMC, ni ngombwa guhitamo inyongeramusaruro zihuye nizindi. Ibi bifasha kwemeza ko imvange ihamye kandi ko buri nyongeramusaruro ikora imirimo yagenewe itabangamiye izindi.
2. Kangura neza: HPMC igomba kuvangwa byuzuye nifu ya putty kugirango irebe ko ikwirakwizwa. Ibi bifasha kwirinda ibibyimba nibibanza bidakomeye hejuru yifu yifu.
3. Kugenzura ubuhehere: Kugenzura ubuhehere ningirakamaro mugihe ukoresheje HPMC nifu yifu. Menya neza ko ifu ya putty idahura nubushuhe bukabije mugihe cyo kubaka, kandi wirinde kubaka mugihe cy'ubushyuhe bwinshi cyangwa ahantu hatose. Nibiba ngombwa, koresha dehumidifier kugirango ugabanye ubuhehere buri mu kirere.
4. Koresha uburyo bukwiye bwo gusaba: Tekinike yo gusaba neza nayo izafasha kwirinda ibisebe. Koresha ifu ya putty muburyo buto, ndetse no murwego hanyuma ubishyire kuri substrate hamwe na trowel cyangwa ibindi bikwiye gushyirwa mubikorwa. Irinde gushyiramo ifu yuzuye cyane, vuba cyane cyangwa n'imbaraga nyinshi.
5. Reba substrate: Substrate ikoreshwaho ifu ya putty nayo igira ingaruka kumpanuka. Menya neza ko substrate yakize neza, isukuye kandi iteguwe mbere yo gushiraho ifu yuzuye. Nibiba ngombwa, primer irashobora gukoreshwa mugutezimbere umubano hagati ya substrate nifu ya putty.
Mu gusoza, kubyimba birashobora kuba ikibazo kibabaza kandi kitagaragara mugihe ukorana na HPMC nifu ya putty. Ariko, iki kibazo kirashobora gukumirwa hitawe kubikoresho, tekiniki nibidukikije birimo. Muguhitamo inyongeramusaruro zihuye, kuvanga neza, kugenzura ubuhehere, ukoresheje tekinoroji ikwiye yo gukoresha, kandi urebye substrate, urashobora kwemeza kurangiza neza, kubusa bitarangiye buri gihe. Nkumushinga wambere wa HPMC, twiyemeje gutanga ibicuruzwa byiza byujuje ibyifuzo byabakiriya bacu. Turizera ko iyi ngingo yafashijwe mugusobanukirwa impamvu HPMC na putty powder ifuro nuburyo bwo kuyirinda.
