I-Hemc isetshenziswe egqoke ijazi le-skim

I-Hydroxyyethyl Methyl Cellulose (Hemc) isetshenziswa kakhulu ekwenziweni kwejazi le-skim njengesengezo esemqoka ukuthuthukisa izakhiwo kanye nokwenza umsebenzi. I-Skim Coat, eyaziwa nangokuthi uqeda udaka noma udonga uPretty, ungqimba oluncanyana lwe-cementional impahla esetshenziswe endaweni ukuze ibushelelezi futhi uyilungiselele ukuqeda ukupenda noma ukuqeda okwengeziwe. Nasi isibukezo sokuthi i-hemc isetshenziswa kanjani kwizicelo ze-skim coat:

1. Isingeniso se-Hydroxyyethyl methyl celtule

1.1 Indima ekwenziweni kwejazi le-skim

I-hemc ingezwa ekwenziweni kwejazi le-skim ukuthuthukisa izakhiwo ezahlukahlukene, kufaka phakathi ukugcinwa kwamanzi, ukusebenziseka kanye namandla anamathela. Inikela ekusebenzeni okuphelele kwejazi le-skim ngesikhathi sokwenza ulapha.

1.2 IZINZUZO ZE-SKIM COATS application

• Ukugcinwa kwamanzi: I-Hemc isiza ukugcina amanzi engxube yejazi le-skim, ukuvimbela ukuhwamuka ngokushesha kanye nokuvumela ukusebenza okunwetshiwe.
• Ukusetshenziswa: I-Hemc ithuthukisa ukusebenziseka kwejazi le-skim, okwenza kube lula ukusakaza, bushelelezi futhi kusebenze ezindaweni ezikhona.
• Amandla okunamathela: Ukungezwa kwe-hemc kungathuthukisa amandla anamathela ejazi le-skim, ukukhuthaza ukunamathela okungcono ku-substrate.
• Ukungaguquguquki: I-Hemc inikela ngokuvumelana nejazi le-skim, ukuvimbela izindaba ezifana nokugcwala kanye nokuqinisekisa ukusetshenziswa okufanayo.

2. Imisebenzi ye-hydroxyyethyl methyl cellulose egqoke ijazi le-skim

2.1 Ukugcinwa kwamanzi

I-Hemc i-hydrophilic polymer, okusho ukuthi inobudlelwano obuqinile emanzini. Ngokwakheka kwejazi le-skim, isebenza njenge-ejenti yokugcinwa kwamanzi, iqinisekisa ukuthi ingxube ihlala isebenza isikhathi eside. Lokhu kubaluleke kakhulu kwizicelo ze-skim coat lapho isikhathi esivulekile esivulekile sifiswa khona.

2.2 Kuthuthukisiwe ukusebenza

I-Hemc ithuthukisa ukusebenziseka kwejazi le-skim ngokunikeza ukuvumelana okubushelelezi nokunokhilimu. Lokhu kusebenza okuthuthukile kuvumela ukusakazeka okulula nokusebenzisa ezindaweni ezahlukahlukene, kuqinisekisa ukuqeda okujabulisa kakhulu.

2.3 amandla anamathela

I-Hemc inikela ngamandla anamathela ejazi le-skim, ukukhuthaza ukubopha okungcono phakathi kwe-skim coat ungqimba kanye ne-substrate. Lokhu kubalulekile ekufezekiseni ukuphela okuhlala isikhathi eside futhi okuhlala isikhathi eside ezindongeni noma ophahleni.

2.4 Ukumelana kwe-SAG

Izici ze-Rheological zosizo lwe-hemc ekuvikeleni ukugcwala noma ukuncipha kwejazi le-skim ngesikhathi sohlelo lokusebenza. Lokhu kubalulekile ekufezekiseni ubukhulu obungaguquki futhi ugweme indawo engalingani.

3. Izicelo ku-skim coat

3.1 Ukuqedwa kodonga lwangaphakathi

I-Hemc isetshenziswa kaningi kuma-skim amajazi enzelwe ukuqeda udonga lwangaphakathi. Kuyasiza ukufeza indawo ebushelelezi futhi efanayo, okulungele ukupenda noma ezinye izindlela zokuhlobisa.

3.2 Ukulungisa futhi kuhlanganiswe amakhompiyutha

Ekulungiswayo nokuqopha amakhompiyutha, i-hemc ithuthukisa ukusebenziseka kanye nokunamathela kokuqukethwe, okwenza kusebenze ngokulungisa ukungapheleli kanye nemifantu ezindongeni nophahla.

3.3 Ukuhlobisa Amandla

Ukuqedwa kokuhlobisa, okufana nokugqokwa okuthenjiwe noma okuphekiwe, ingculaza ye-hemc ekugcineni ukuguquguquka okudingayo nokusebenza, okuvumela ukudalwa kwemiphumela ehlukahlukene yokuhlobisa.

4. Ukucatshangelwa kanye nokuqapha

4.1 umthamo kanye ukuhambisana

Umthamo we-hemc ekwenziweni kwejazi le-skim kufanele alawulwe ngokucophelela ukuze afinyelele izakhiwo ezifunwayo ngaphandle kokuthinta ezinye izici. Ukuvumelana nezinye izengezo nezinto zokwakha nakho kubalulekile.

4.2 Umthelela Wezemvelo

Ukucatshangelwa kufanele kunikezwe umthelela wezemvelo wezithasiselo zokwakha, kufaka phakathi i-hemc. Izinketho ezizinzile futhi ezinobungane ziya ngokuya zibaluleke kakhulu embonini yezokwakha nokwakha.

4.3 Imininingwane Yomkhiqizo

Imikhiqizo ye-Hemc ingahluka ngokucaciswa, futhi kubalulekile ukukhetha ibanga elifanele ngokususelwa kwizidingo ezithile zohlelo lokusebenza lweChim Coup.

5. Isiphetho

Ngokwesimo se-skim coats, i-hydroxyyethyl methyl cellulose iyisengezo esibalulekile esithuthukisa ukugcinwa kwamanzi, ukusebenziseka, amandla anamathela, kanye nokungaguquguquki. Ama-skim amajazi ahlelwe nge-hemc ahlinzeke ngokuqedwa okubushelelezi, okuhlala isikhathi eside, kanye nokuqedwa okujabulisa ngobuhle ezindongeni ezingaphakathi nophahla. Ukucatshangelwa ngokucophelela kwemithamo, ukuhambisana, kanye nezici zezemvelo kuqinisekisa ukuthi i-hemc yandisa izinzuzo zayo izinhlelo ezihlukile ze-skim coat.
