Ukuthuthukisa Ukusebenza Kwe-Putty ne-Gypsum Ukusebenzisa i-MHEC

Ukwenziwa ngcono kwe-putty ne-gypsum powder ngokufaka i-methylhydroxyethylcellulose (MHEC). I-MHEC iyi-polymer esekelwe ku-cellulose esetshenziswa kakhulu ezintweni zokwakha ngenxa yokugcinwa kwamanzi, ukuqina kanye nezakhiwo ze-rheological. Lolu cwaningo luphenye umphumela we-MHEC ezicini zokusebenza ezibalulekile ze-putty ne-stucco, okuhlanganisa ukusebenza, ukunamathela kanye nesikhathi sokusetha. Okutholakele kusiza ukuthuthukisa ikhwalithi isiyonke kanye nokutholakala kwalezi zinto zokwakha ezibalulekile.

ethula:

1.1 Isendlalelo:

I-putty ne-stucco yizingxenye ezibalulekile ekwakhiweni, ezihlinzeka ngezindawo ezibushelelezi, ezimboza ukungapheleli, nokuthuthukisa ubuhle besakhiwo. Izakhiwo zalezi zinto, njengokucutshungulwa nokunamathela, zibalulekile ekusetshenzisweni kwazo ngempumelelo. I-Methylhydroxyethylcellulose (MHEC) idonse ukunaka kwamandla ayo okuthuthukisa ukusebenza kwezinto zokwakha.

1.2 Izinjongo:

Inhloso eyinhloko kwakuwukufunda umphumela we-MHEC ezindaweni ze-putty ne-gypsum powder. Izinjongo ezithile zihlanganisa ukuhlola ukucutshungulwa, amandla ebhondi, kanye nokusetha isikhathi sokuthuthukisa ukwakhiwa kwalezi zinto zokusebenza.

Ukubuyekeza incwadi:

2.1 I-MHEC ezintweni zokwakha:

Ucwaningo lwangaphambilini luye lwagqamisa ukuguquguquka kwezinto ezihlukahlukene ze-MHEC ekuthuthukiseni ukusebenza kwezinto ezihlukahlukene zokwakha, okuhlanganisa udaka olusekelwe kusimende kanye nemikhiqizo eyenziwe nge-gypsum. Ukubuyekezwa kwezincwadi kuhlola izindlela i-MHEC ethinta ngayo ukusebenza, ukugcinwa kwamanzi, nokunamathela.

2.2 Amaresiphi we-putty ne-plaster:

Ukuqonda izithako kanye nezidingo ze-putty ne-gypsum powder kubalulekile ekwenzeni ingxube ephumelelayo. Lesi sigaba sibuyekeza ukwakheka kwendabuko futhi sikhombe izindawo okufanele zithuthukiswe ekusebenzeni nasekusimameni.

indlela:

3.1 Ukukhetha okubalulekile:

Ukukhetha ngokucophelela izinto zokusetshenziswa, okuhlanganisa i-putty ne-gypsum powder kanye ne-MHEC, kubalulekile ekufinyeleleni imiphumela oyifunayo. Ucwaningo luveza ukucaciswa kwezinto ezisetshenziswayo kanye nesizathu sokukhethwa kwazo.

3.2 Idizayini yokuhlola:

Uhlelo lokuhlola oluhlelekile lwasungulwa ukuze kuhlaziywe umphumela wokugxilisa okuhlukile kwe-MHEC kuzakhiwo ze-putty ne-stucco. Amapharamitha angukhiye afana nokusebenza, amandla ebhondi kanye nesikhathi sokusetha kukalwa kusetshenziswa izindlela zokuhlola ezijwayelekile.

Imiphumela nengxoxo:

4.1 Ukwakhiwa:

Umthelela we-MHEC ekusebenzeni kwe-putty ne-stucco uhlolwa ngokuhlolwa okufana nokuhlolwa kwebhentshi lokugeleza kanye nokuhlolwa kokuwohloka. Imiphumela yahlaziywa ukuze kutholwe ukugxilwa kwe-MHEC okuphelele okulinganisa ukucutshungulwa okuthuthukisiwe ngaphandle kokuyekethisa ezinye izakhiwo.

4.2 Amandla okunamathela:

Amandla ebhondi e-putty ne-stucco abalulekile ekutheni ahlangana kanjani nama-substrates ahlukahlukene. Ukuhlolwa kokukhipha kanye nokulinganisa amandla ebhondi kwenziwa ukuze kuhlolwe umphumela we-MHEC ekunamatheleni.

4.3 Setha isikhathi:

Isikhathi sokusetha siyipharamitha ebalulekile ethinta ukusetshenziswa nokomisa kwe-putty ne-stucco. Lolu cwaningo luphenye ukuthi ukugxilisa okuhlukene kwe-MHEC kusithinta kanjani isikhathi sokusetha nokuthi ingabe likhona yini ibanga elifanele elifanele ukusetshenziswa okusebenzayo.

Ekuphetheni:

Lolu cwaningo lunikeza ukuqonda okubalulekile ekusetshenzisweni kahle kwama-putty nama-gypsum powders kusetshenziswa i-MHEC. Ngokuhlaziywa okuhlelekile kwemiphumela ye-MHEC ekusebenzeni, amandla ebhondi kanye nesikhathi sokusetha, ucwaningo luhlonze ukubunjwa okuphelele ukuze kuthuthukiswe ukusebenza okuphelele. Lokhu okutholakele kungasiza ukuthuthukisa izinto zokwakha ezithuthukisiwe ngokusebenza okuthuthukisiwe nokuzinza.

Indlela yesikhathi esizayo:

Ucwaningo lwesikhathi esizayo lungase luhlole ukuqina kwesikhathi eside kanye nesimo sezulu se-MHEC-modified putty and stuccoes. Ukwengeza, izifundo zokuba nokwenzeka kwezomnotho kanye nokwanda kokwakheka okuthuthukisiwe zingase zisekele ukusetshenziswa okungokoqobo kwalezi zinto embonini yezokwakha.
