ethula
I-Dry-mix mortar iyingxube kasimende, isihlabathi, nezinye izithasiselo ezisetshenziselwa ukunamathisela amathayela, ukuvala izikhala, kanye nezindawo ezibushelelezi.Inhlanganisela efanele yezithako ibalulekile ekwenzeni udaka olusebenza kahle kakhulu olunesibopho esihle kakhulu, amandla nokuqina.Ngakho-ke abakhiqizi basebenzisa i-hydroxypropyl methylcellulose (HPMC) njengesithako esibalulekile ekwakhiweni kodaka lwengxube eyomile.I-HPMC iyi-polymer etholakala ku-cellulose encibilika emanzini futhi isetshenziswa kabanzi embonini yezokwakha ngenxa yezakhiwo zayo ezihlukile ze-rheological.
Ukuhlolwa kwebanga le-HPMC
Kunezinhlobonhlobo zamabanga e-HPMC emakethe, ngalinye linezindawo ezihlukile namandla athinta ukusebenza komkhiqizo wokugcina.Ngakho-ke, abakhiqizi be-dry-mix mortar badinga ukuhlola amamaki e-HPMC ahlukahlukene ukuze bakhethe elifaneleka kakhulu ekwakhiweni komkhiqizo wabo.
Okulandelayo yizibaluli ezibalulekile abakhiqizi abazihlolayo lapho behlola amamaki e-HPMC ekwakhekeni kodaka lwengxube eyomile:
1. Ukugcinwa kwamanzi
Ukugcinwa kwamanzi yikhono le-HPMC lokubamba amanzi futhi livimbele ukuhwamuka ngesikhathi senqubo yokwelapha.Ukugcina izinga le-hydration yodaka lwakho nokuqinisekisa ukuthi lwelapheka kahle kubalulekile, ikakhulukazi ezindaweni ezishisayo nezomile.Umthamo ophezulu wokubamba amanzi kubangela izikhathi ezinde zokuphulukisa, okuholela ekukhiqizeni okuphansi.Ngakho-ke abakhiqizi bafuna ukuthola ibhalansi efanele phakathi kokugcinwa kwamanzi kanye nesikhathi sokwelapha lapho bekhetha amabanga e-HPMC.
2. Amandla aqina
Ukuqina komthamo we-HPMC isilinganiso samandla ayo okwandisa i-viscosity yodaka.Izithombo ze-viscosity eziphezulu zinezakhiwo ezingcono zokuhlanganisa kanye nezibopho, ezizenza zibe zilungele izinhlelo zokusebenza zokwakha.Kodwa-ke, ukuqina ngokweqile kungabangela ukuthi umkhiqizo ugoqe, okwenza ukuxuba nokusabalalisa kube nzima.Ngakho-ke abakhiqizi badinga ukuhlola amamaki e-HPMC kabanzi ukuze baqinisekise amandla amakhulu okujiya ane-viscosity elinganiselwe kanye nokusebenziseka kalula.
3. Hlela isikhathi
Isikhathi sokumiswa kwezisindo zengxube eyomile siyisici esibalulekile esithinta ukukhiqiza kanye nekhwalithi yomkhiqizo wokugcina.Izikhathi zokusetha ezinde ziholela ekukhiqizeni okuphansi, izindleko eziphezulu zabasebenzi, kanye nokuncipha kokwaneliseka kwamakhasimende.Ngakho-ke, abakhiqizi badinga ukukhetha ibanga le-HPMC elizonikeza isikhathi esingcono kakhulu sokusetha ngenkathi beqinisekisa ukuthi umkhiqizo welaphekile ngendlela efanele.
4. Ukwakhiwa kwefilimu
Isakhiwo sokwenza ifilimu ikhono le-HPMC ukwenza ungqimba oluvikelayo phezu kodaka olulashiwe.Lolu ungqimba lunikeza isivikelo ezintweni ezihlukahlukene zemvelo ezifana nomoya, imvula nomswakama futhi lusiza ekwandiseni ukuphila komkhiqizo wokugcina.Ngakho-ke abakhiqizi bahlose ukukhetha amamaki e-HPMC ahlinzeka ngokwakhiwa kwefilimu ephezulu enemiphumela engemihle emincane njengokufiphala, ukushintsha kombala noma ukuxebuka.
5. Ukuhambisana nezinye izinamathiselo
Ama-dry-mix mortars asebenzisa inhlanganisela yezibophezelo ukuze afinyelele ukusebenza okuphezulu.Kodwa-ke, akuwona wonke ama-adhesives ahambisana ne-HPMC, okungaholela ekunciphiseni ukubumbana, ukunamathela namandla esibopho.Ngakho-ke, abakhiqizi bavivinya amamaki e-HPMC kakhulu ukuze banqume ukuhambisana kwawo nezinye izinto ezinamathelayo futhi bakhethe leyo enikeza imiphumela engcono kakhulu.
I-HPMC iyisithako esiyinhloko ekwakhiweni kodaka lwengxube eyomile, okuthinta ukusebenza kwayo nokuqina.Ngakho-ke, abakhiqizi badinga ukuhlola amamaki e-HPMC ahlukahlukene ukuze bakhethe elilodwa elinikeza ukugcinwa kwamanzi okungcono kakhulu, amandla okuqina, isikhathi sokusetha, ukwakheka kwefilimu, nokuhambisana nezinye izinto zokunamathela.Ukuhlola amamaki e-HPMC kuyisinyathelo esibalulekile ekudaleni udaka lwengxube eyomile olusebenza kahle oluletha ukusebenza okuhlala isikhathi eside, ukwaneliseka kwamakhasimende kanye nenzuzo eyengeziwe.Ngenhlanganisela efanele yamabanga nezithako ze-HPMC, ama-dry-mix mortars anganikeza amandla ebhondi amahle kakhulu, ukuqina kanye nokusebenziseka kalula, okuwenza alungele izinhlelo zokusebenza ezihlukahlukene zokwakha.
