Kungani sidinga ukuzilinganisa?

Embonini yesimanje yokwakha kanye nophahla, ukuthola indawo ebushelelezi ngokuphelele, eqondile akuseyona into yokunethezeka—kuyisidingo. Njengoba izinhlelo zophahla ziba zithuthuke kakhulu futhi amazinga okuklama eqhubeka ekhuphuka, izindlela zendabuko zokulinganisa izilinganiso ngokuvamile azanele ukuhlangabezana nokulindelwe kwanamuhla. Yilapho-keizinhlanganisela ezizilinganisayongena emsebenzini.

Izinto zokwakha ezizilinganisayo zishintshe kakhulu ukulungiswa kwephansi ngokunikeza izixazululo zokuzilinganisa ezisheshayo, ezisebenzayo, nezinembile kakhulu. Zisekelwa yizinto ezintsha ezivela kubaholi bamakhemikhali bomhlaba wonke njengeSika AG, BASF SE, kanye neMapei SpA, le mikhiqizo manje isetshenziswa kabanzi kumaphrojekthi okwakha ezindawo zokuhlala, ezentengiselwano, kanye nezimboni.

Lesi sihloko sinikeza umbono ophelele wesitayela sezindabaukuthi yiziphi izinhlanganisela ezizilinganisayo, ukuthi zisebenza kanjani, nokuthi kungani zibalulekile ekwakheni kwanamuhla.

1. Iyini Inhlanganisela Ezimele?

Inhlanganisela ezilinganisayo iyi-izinto ezisekelwe kusimende noma ze-gypsumYakhelwe ukugeleza kalula futhi isakazeke endaweni ethile, yakha ungqimba olubushelelezi, oluyisicaba, nolulinganayo ngaphandle kwesidingo sokuqedela ngesandla okubanzi. Ngokungafani nodaka lwendabuko, oludinga abasebenzi abanekhono ukuze kufinyelelwe indawo elinganayo, ama-compounds azilinganisayo asebenzisa ukugeleza kwawo kanye namandla adonsela phansi ukuze ahlale ngokulinganayo.

Ukwakheka Okuyisisekelo

Inhlanganisela ejwayelekile yokuzilinganisa ihlanganisa:

• Isibophezeli sikasimende noma se-gypsum
• Izithako ezincane (njengesihlabathi noma i-calcium carbonate)
• Impuphu ye-polymer ephinde ihlakazeke (I-RDP)
• Ama-ether e-cellulose (isb.,I-HPMC)
• Ama-Superplasticizer
• Ama-defoamer kanye nama-stabilizer

Ingxenye ngayinye idlala indima ethile ekuqinisekiseni ukugeleza, ukuzinza, kanye namandla okugcina.

Isimiso Sokusebenza

Uma ixutshwe namanzi, inhlanganisela yakha i-i-slurry ewuketshezi kakhuluNgenxa yezithasiselo ezithuthukisiwe, lokhu:

• Igeleza kalula ngaphesheya kwe-substrate
• Igcwalisa izindawo eziphansi kanye nokungapheleli
• Izinga ngokwalo ngaphandle kokungenelela ngesandla

Ngemva kokusetshenziswa, kuyaqina kube indawo ebushelelezi nehlala isikhathi eside, ilungele ukumbozwa phansi.

2. Kungani Sidinga Ama-Compounds Azilinganisayo?

2.1 Ukuqinisekisa Ubuso Obuyisicaba Nobubushelelezi

Izinto zokwakha phansi zesimanje ezifana namathayili, i-vinyl, i-laminate, kanye ne-epoxy coatings zidingai-substrate esezingeni elifaneleNgisho nokungahambi kahle okuncane kungabangela:

• Izindawo ezingalingani
• Ukunamathela okubi
• Ukugqoka ngaphambi kwesikhathi

Ama-compounds azimele aqeda lezi zinkinga ngokudala isisekelo esifanayo.

2.2 Ukuthuthukisa Ukusebenza Kwephansi Nokuqina Kwalo

Ubuso obuqondile buqinisekisa:

• Ukusatshalaliswa komthwalo okungcono
• Ukucindezeleka okuncishisiwe ezintweni zokwakha phansi
• Impilo yesevisi ende

Ngaphandle kokulungiswa kahle, izinhlelo zokubeka phansi zivame ukuqhekeka, ukuphakanyiswa, kanye nokwehluleka.

2.3 Ukwandisa Ukusebenza Kahle Kokwakha

Izindlela zendabuko zokulinganisa yilezi:

• Kudinga abasebenzi abaningi
• Kuthatha isikhathi
• Kuxhomeke kubasebenzi abanamakhono

Ama-compounds azimele anikeza:

• Isicelo esisheshayo
• Izindleko zabasebenzi ezincishisiwe
• Imiphumela ehambisanayo

Lokhu kuthuthukisa kakhulu ukusebenza kahle kokwakhiwa.

2.4 Ukuhambisana Nezinhlelo Zokwakha Zanamuhla

Ama-compounds azimele abalulekile ku:

• Izinhlelo zokufudumeza ezingaphansi komhlaba
• Amathayili amakhulu
• Uphansi lwezimboni

Zinikeza ukunemba okudingekayo kubuchwepheshe bezakhiwo obuthuthukisiwe.

3. Izakhiwo Eziyinhloko Zama-Compounds Azilinganisayo

3.1 Ukugeleza Okuphezulu

Ikhono lokugeleza nokusabalala ngokulinganayo yilona sici esiyinhloko. Ama-superplasticizer athuthukisiwe aqinisekisa ukusetshenziswa okubushelelezi ngaphandle kokuhlukanisa.

3.2 Ubuso Obuziphilisayo

Amaphutha amancane ebusweni alungiswa ngokuzenzakalelayo ngesikhathi sokugeleza, okuholela ekuqedeni okubushelelezi.

3.3 Ukuthuthukiswa Okusheshayo Nokuthuthuka Kwamandla

Izinhlobo eziningi zinikeza izikhathi zokomisa ngokushesha, okuvumela:

• Ukufakwa okusheshayo kwezimbozo zaphansi
• Izikhathi zephrojekthi ezincishisiwe

3.4 Ukunamathela Okuqinile

Ukuguqulwa kwe-polymer kuthuthukisa ukubopha ne-substrates, okuqinisekisa ukuqina kwesikhathi eside.

3.5 Ukuqina Kobukhulu

Ukuncipha okuphansi kunciphisa ingozi yokuqhekeka nokuguquka.

4. Indima Yezithasiselo Eziyinhloko Kumakhemikhali Azilinganisayo

I-Cellulose Ether (I-HPMC)

Ihlinzeka:

• Ukugcinwa kwamanzi
• Ukulawula ukuthambekela

• Ukulungiswa kwezinga

7. Izinzuzo Kunezindlela Zendabuko

Uma kuqhathaniswa nokulinganisa ngesandla:

• Ukunemba okuphezulu
• Ukufakwa okusheshayo
• Izidingo zomsebenzi eziphansi
• Ikhwalithi engcono yobuso

Lezi zinzuzo zenza ukwakheka kwe-self-leveling kube yisinqumo esithandwayo ekwakheni kwesimanje.

8. Izinselele kanye Nokucatshangelwa

Naphezu kwezinzuzo zazo, ukusetshenziswa okufanele kubalulekile:

• Isilinganiso samanzi esifanele
• Ukulungiswa okufanele kwe-substrate
• Izimo zemvelo ezilawulwayo

Ukwehluleka ukulandela iziqondiso kungathinta ukusebenza kahle.

9. Izitayela Zemakethe Nokuthuthukiswa Kwemboni

Imakethe yomhlaba wonke yamakhemikhali azimele ikhula ngokushesha, iqhutshwa yi:

• Ukufudukela emadolobheni
• Isidingo sephansi elisezingeni eliphezulu
• Ukwamukelwa kwezinhlelo zodaka oluxutshwe okomile

Izinkampani ezifana neSika AG kanye neMapei SpA zihamba phambili ekusunguleni izinto ezintsha kulo mkhakha.

10. Umbono Wesikhathi Esizayo

Intuthuko yesikhathi esizayo ihlanganisa:

• Izakhi ezinobungani nemvelo
• Izinhlelo zokulungisa ezisheshayo
• Izinto ezihlakaniphile ezinokusebenza okuthuthukisiwe

Isidingo samakhemikhali azilinganisayo sizoqhubeka sikhula njengoba amazinga okwakha ethuthuka.
