I-Putty kanye nezakhiwo ze-plaster zisebenzisa i-MHEC

I-MHEC, noma i-methylhydroxyethylcellulose, iyisengezo samakhemikhali esibalulekile esisetshenziswa kabanzi ezintweni zokwakha. Ikakhulukazi ekugqokeni nasekuqedeni izinto ezifana ne-putty ne-plaster, indima ye-MHEC ibaluleke kakhulu.

1. Ukusebenza kwe-MHEC ku-putty

I-Putty iyimpahla esetshenziselwa ukugcwalisa izindonga ezingalingani noma ezinye izindawo. Kudingeka kube nokusebenza okuhle kokwakhiwa, amandla nokuqina. Ukusetshenziswa kwe-MHEC ku-putty ikakhulukazi kufaka phakathi izici ezilandelayo: 

a. Ukuqina komphumela

I-MHEC ingakhuphula kakhulu i-viscosity ye-putty futhi ithuthukise uketshezi nokwakhiwa kwayo. Lo mphumela wokujiya ungasiza ukulawula ukuvumelana kwe-putty, kwenze kube lula ukufaka nokugcina ukujiya okuhle ezindaweni eziqondile ngaphandle kokugoqa. Ukuqina okufanele nakho kungathuthukisa ukusebenza kwe-anti-sag ye-putty, okwenza ukwakhiwa kube lula.

b. Ukugcinwa kwamanzi

I-MHEC inokugcinwa kwamanzi okuhle, okubalulekile ekusebenzeni kwe-putty. I-Putty ithatha isikhathi esithile ukuze yome futhi iqine ngemva kokufaka isicelo. Uma umswakama ulahleka ngokushesha, kuzokwenza ukuthi ubuso be-putty buqhekeke noma bube yimpuphu. I-MHEC ingenza ifilimu egcina amanzi ku-putty futhi inciphise izinga lokukhuphuka kwamanzi, ngaleyo ndlela iqinisekise ukomiswa okufanayo kwe-putty, ukunciphisa ukwakheka kwemifantu, nokuthuthukisa ikhwalithi yomkhiqizo ophelile.

c. Thuthukisa ukunamathela

I-MHEC ingathuthukisa ukunamathela kwe-putty, ikwenze ukunamathela okwengeziwe kuma-substrates ahlukene. Lokhu kubalulekile ekuzinzeni nasekuqineni kongqimba lwe-putty. Ukunamathela okuhle akukwazi nje ukuvimbela i-putty ekuweni, kodwa futhi kwandise ukumelana nomthelela we-putty futhi kwandise impilo yayo yesevisi.

2. Ukusebenza kwe-MHEC egypsum

I-Gypsum iyimpahla yokwakha evame ukusetshenziswa enokumelana okuhle nomlilo kanye nemiphumela yokuhlobisa. Indima ye-MHEC ku-gypsum ayikwazi ukushaywa indiva. Izici zayo eziyinhloko zimi kanje:

a. Thuthukisa ukusebenza kokucubungula

I-MHEC ithuthukisa izakhiwo zokucubungula ze-plaster, okwenza kube lula ukuxutshwa nokusabalalisa. Ngokulungisa i-viscosity kanye nokuvumelana kwe-gypsum slurry, i-MHEC ingasiza abasebenzi bokwakha balawule kangcono inani nokuqina kwe-gypsum esetshenzisiwe. Lokhu kuzuzisa kakhulu ukuthuthukisa ukusebenza kahle kokwakhiwa kanye nokugcwala komkhiqizo oqediwe.

b. Thuthukisa ukumelana nokuqhekeka

I-Plaster ijwayele ukuncipha imifantu ngesikhathi senqubo yokuqina, engathinta ukubukeka kwayo nokusebenza kwayo. Ukusebenza kokugcinwa kwamanzi kwe-MHEC kunganciphisa ngokuphumelelayo izinga lokukhuphuka kwamanzi ku-gypsum, ukunciphisa ukwakheka kokucindezeleka kwangaphakathi, ngaleyo ndlela kunciphise izigameko zokuqhekeka. Ngaphezu kwalokho, i-MHEC ingathuthukisa ukuguquguquka kwe-plaster, ikwenze imelane nokucindezela kwangaphandle.

c. Thuthukisa ukushelela kwendawo

Ukusetshenziswa kwe-MHEC ku-gypsum kungabuye kuthuthukise ukushelela kwayo kwendawo futhi kwenze ukubukeka kwemikhiqizo ye-gypsum kube kuhle kakhulu. Indawo ebushelelezi ayinayo nje umphumela ongcono wokuhlobisa, kodwa futhi inikeza isisekelo esingcono sokunamathela ngopende, okwenza kube lula izinqubo zokudweba ezilandelayo.

Njengesengezo sezinto zokwakha ezibalulekile, i-MHEC ikhombisa izakhiwo eziningi eziphakeme lapho isetshenziswa ku-putty ne-gypsum. Akukwazi nje ukuthuthukisa ukusebenza kokwakhiwa, ukuthuthukisa ukunamathela nokugcinwa kwamanzi kwezinto, kodwa futhi kuthuthukise kakhulu ukumelana nokuqhekeka kanye nekhwalithi yobuso bomkhiqizo ophelile. Lezi zakhiwo zenze i-MHEC yasetshenziswa kabanzi embonini yezokwakha, yaba yingxenye ebalulekile yezinto ezifana ne-putty ne-plaster. Esikhathini esizayo, ngokuthuthukiswa kobuchwepheshe bokwakha kanye nokuthuthukiswa kwezidingo zokusebenza kwezinto ezibonakalayo, amathemba okufaka isicelo se-MHEC azoba banzi.
