Isingeniso
Ukwakhiwa kwesimanje kudlule kakhulu kunezingxube zesihlabathi nesamente zendabuko. Izinhlelo zodaka oluxutshwe ngosawoti zanamuhla ziyizindlela eziklanywe kahle kakhulu ezenzelwe ukuhlangabezana nezidingo zokusebenza eziqinile ezifana namandla aphezulu okunamathela, ukumelana nokuqhekeka, ukusebenza kahle, ukugcinwa kwamanzi, ukuqina, kanye nokumelana nemvelo.
Ukuze kufezwe lezi zakhiwo, izithasiselo zamakhemikhali zidlala indima ebalulekile. Ngisho noma zisetshenziswa ngobuningi obuncane, izithasiselo zinquma ukusebenza kokugcina kwezinhlelo zodaka ngaphezu kwanoma iyiphi enye ingxenye ngaphandle kwesimende.
Lesi sihloko sihlolaizithasiselo ezinhlanu ezibalulekile ze-mortar, imisebenzi yazo, izindlela zazo, nokuthi kungani zibalulekile ezintweni zokwakha zesimanje.
1. I-Cellulose Ether (HPMC / MHEC / HEC)
Ama-cellulose ethers angumgogodla wobuchwepheshe besimanje be-mortar. Izinhlobo ezivame ukusetshenziswa zifaka:

Ukuthuthukiswa Kokuguquguquka
Kunciphisa ubuthakathaka bezinto ezisekelwe kusimende.
Ukumelana Nokuqhekeka
Kuyasiza ekubambeni ukucindezeleka okubangelwa ukushintsha kwezinga lokushisa kanye nokunyakaza kwesakhiwo.
Ukumelana Namanzi
Kunciphisa ukuvuleka kwamanzi futhi kuthuthukisa ukuqina.
Kungani Kubalulekile
I-RDP iguqula izinhlelo zikasimende eziqinile zibeizimbotshana eziguquguqukayo nezisebenza kahle kakhulukufanelekile ezinhlelweni zesimanje ezifana nalezi:
- Izinamathiseli zethayela
- Izinhlelo ze-EIFS
- Lungisa izimbotshana
3. Ama-Superplasticizer (i-PCE - i-Polycarboxylate Ether)
Ama-Superplasticizer ayizinto zokunciphisa amanzi ezisetshenziswa kakhulu ezinhlelweni zesimanje zesimende.
Imisebenzi Eyinhloko
Ukunciphisa Amanzi
Zinciphisa isidingo samanzi ngenkathi zigcina ukusebenza kahle.
Ukuthuthukiswa Kwamandla
Ukuqukethwe kwamanzi aphansi kuholela emandleni aphezulu okucindezela.
Ukuthuthukiswa Kokugeleza
Zithuthukisa ukugeleza kwamanzi kuma-compounds kanye nama-grout azimele.
Kungani Kubalulekile
Ama-Superplasticizer avumela:
- Udaka olunamandla aphezulu
- Izinhlelo zokuzilinganisa
- Izicelo zekhonkrithi empompayo
Zibaluleke kakhuluizinhlelo zesamente ezisebenza kahle kakhulu, ezingasebenzisi amanzi amaningi.
4. Ama-ejenti Okuqeqesha Ngomoya
Izinto ezifaka umoya zingenisa amabhamuza omoya amancane alawulwayo ku-mortar.
Imisebenzi Eyinhloko
Ukumelana Nokuqandisa–Ukuncibilika
Izikhala zomoya zimunca ingcindezi yokukhula evela emanzini aqandisayo.
Ukusebenza Okuthuthukisiwe
Zenza kube lula ukufaka nokusakaza udaka.
Ubuningi Obuncishisiwe
Ubuningi obuphansi buthuthukisa ukuvikela ukushisa.
Kungani Kubalulekile
Ezindaweni ezibandayo, izinto zokungenisa umoya zibalulekile ku:
- Iplasta yangaphandle
- Izimbozo zokulungisa umgwaqo
- Ukwakhiwa kwesimo sezulu esibandayo
Zithuthuka kakhuluukuqina ngaphansi kwezimo zemvelo ezinzima.
5. Abahlehlisi kanye nabalawuli bokubeka
Ama-retarders alawula izinga lokumuncwa kwesimende.
Izinhlobo ezivamile zifaka:
- I-asidi ye-citric
- I-asidi ye-tartaric
- Amakhemikhali asekelwe ku-phosphate
Imisebenzi Eyinhloko
Ukusetha Ukulawula Isikhathi
Zibambezela izikhathi zokuqala nezokugcina zokusetha.
Isandiso Sokusebenza
Zivumela isikhathi eside sokusebenza ezindaweni ezinkulu zokwakha.
Vimbela Ukuqina Kwangaphambi Kwesikhathi
Kubalulekile ekusetshenzisweni kwesimo sezulu esishisayo.
Kungani Kubalulekile
Ngaphandle kokusetha ukulawula:
- Udaka lungase luqine ngokushesha kakhulu
- Ikhwalithi yohlelo lokusebenza iyancipha
- Ukwanda kwemfucuza
Abahlehlisi babalulekileukulawula izinga lokushisa kanye nokuguquguquka kokwakhiwa.
Imiphumela Yokubambisana Yezithasiselo
Ezinhlelweni zesimanje ze-mortar, izithasiselo azisebenzi ngokuzimela.
Kunalokho, bayasebenzisana:
- I-cellulose ether → ukugcinwa kwamanzi + ukusebenza kahle
- I-RDP → ukuguquguquka + ukunamathela
- I-PCE → ukugeleza + amandla
- Izithambisi zomoya → ukuqina
- Abahlehlisi → ukulawula isikhathi
Ndawonye bakhauhlelo lodaka olusebenza kahle kakhulu olulinganiselayo.
Izindawo Zokusetshenziswa Kodaka Oluguquliwe
Izimbotshana zesimanje ezisekelwe ekungezeni zisetshenziswa ku:
- Izinamathiseli zethayela (izinhlelo ze-C1, C2)
- I-putty yodonga kanye namajazi athambile
- Izinhlanganisela ezizilinganisayo
- Izinhlelo zokuvikela ugesi ze-EIFS
- Lungisa izimbotshana
- Amaplasta asekelwe ku-gypsum
Ukusetshenziswa ngakunye kudinga ibhalansi ehlukile yezithasiselo.
Ukubaluleka Kwezomnotho
Nakuba izithasiselo zimelela iphesenti elincane lezindleko zokwakheka, zinikeza:
- Ukwehluleka kokwakha okunciphile
- Izindleko zokulungisa eziphansi
- Ukusebenza kahle kokufakwa okuphezulu
- Isikhathi sokuphila kwesakhiwo esithuthukisiwe
Bangomunye waboizingxenye ze-ROI eziphakeme kakhulu kumakhemikhali wokwakha.
Imikhuba Yezemvelo
Izithasiselo zanamuhla ziya ngokuya ziba:
- Okusekelwe ku-bio (izinto ezisuselwe ku-cellulose)
- I-VOC ephansi
- Ukukhiqiza okusebenzisa amandla kahle
Ukusimama sekuba yinto ebalulekile ekuthuthukisweni kwezinto ezintsha.
Ukusebenza kodaka lwesimanje kuncike kakhulu ezithasiselweni zamakhemikhali. Izithasiselelo ezinhlanu ezibalulekile—ama-cellulose ether,I-RDP, ama-superplasticizer, ama-air-entraining agents, kanye nabalawuli bokubeka—basebenzisana ukuguqula izingxube zesimende eziyisisekelo zibe izinto zokwakha ezisebenza kahle kakhulu.
Ukuqonda lezi zithasiselo kuvumela abakhiqizi kanye nabakhi ukuthi baklame izitini ezihlangabezana nezidingo zokwakha zesimanje: eziqinile, eziguquguqukayo, ezihlala isikhathi eside, futhi ezisebenza kahle kakhulu.
Njengoba izindinganiso zokwakha ziqhubeka nokukhula, ubuchwepheshe bokwengeza buzohlala buyisisekelo sokusungula izinto ezintsha ezinhlelweni ze-mortar.
